Description

The utility model relates to the field of mechanical engineering, namely to devices for air intake into internal combustion engines.

A known system for purifying the air of an internal combustion engine, comprising at least two air purifiers interconnected by a pipe, the pipe connecting the air purifiers from the sides of the exhaust pipes and provided with at least one lateral outlet. In addition, a clogged air filter sensor is installed in the pipe (see patent RU No. 127129, IPC F02M 35/024 (2006.01), published on 04/20/2013).

The air supply system of an internal combustion engine is also known, comprising an air filter with an air intake device and an air duct connecting the air filter to the engine, while an opening is made in the air duct connected by a hose to the nozzle of the resonator chamber, an insert in the form of a pipe protruding in the nozzle of the resonator chamber inside the resonator chamber, in addition, the insert is installed with the possibility of changing the size of its protrusion (patent RU No. 2244847, IPC F02M 35/10, publ. 20.01.2005).

Also known is an air supply system of an internal combustion engine, comprising an air intake, an air filter, an air duct with a throttle device installed therein, means for measuring air flow parameters and a resonator chamber connected thereto, communicating through an inlet with a receiver having separate air supply pipes to the cylinders of the internal engine combustion, while the inlet is located in the receiver area opposite between the first and second from the side of the duct connection of the individual air supply pipes to the cylinders of the internal combustion engine and the remaining individual pipes, the resonator chamber is L-shaped, one longitudinal part of which communicates with the duct through the protruding inside the chamber there is a tubular insert and has a transverse narrowing, and the other transverse part is located above the individual nozzles for supplying air to the cylinders of the internal combustion engine and is docked with a cover docked with another Rons with a receiver (patent RU No. 65979, F02M 35/10 (2006.01), publ. 08/27/2007).

A vertical air intake system is known for use in a motor vehicle that has an engine compartment closed by a hood and a cleaned air inlet, the system at least partially extending outside the engine compartment closed by a hood, supplies purified air to an engine compartment closed by a hood and contains a vertical a nozzle with an air inlet and an air outlet, an air purifier body that receives air from the air outlet and which contains a rough cleaning and air exhaust area and an opening for accessing the rough and exhaust air area, a process hatch covering the opening for access in the air cleaner housing, a filter element placed in the air cleaner housing, as well as an air cleaner housing with a hole for the release of purified air, which serves to supply purified air to the engine compartment closed by the hood. At the same time, the air filtering element contains a filtering structure, an elbow and a sealing element. The filtering structure comprises a block filtering material with a raw air inlet opening and a purified air outlet for flowing through which air moves in a first axial direction, while the cleaned air outlet opening limits the cross-sectional area of the filter structure. The knee has a first end extending from the hole for discharging purified air from the filter structure, a second end flowing through which air moves in a second axial direction, and an air chamber extending from the first end of the knee to the second end of the knee. The air chamber comprises an air deflector for changing the first axial direction of the air to a second axial direction, the second axial direction being different from the first axial direction and the internal volume between the first end of the knee and the second end of the knee. At the second end of the knee, a sealing element of the filter element is installed, which is hermetically connected to the hole for the intake of purified air and limits the cross-sectional area of the sealing element (patent RU No. 2670852, IPC B01D 46/24 (2006.01), F02M 35/024 (2006.01), publ. . 10.25.2018).

Known solutions in most cases have a specific purpose or create sufficiently large dimensions of the air filtration system when assembling in a car, or have a sufficiently large number of complex component components and their elements.

The closest to the claimed technical solution for the combination of essential features is an air intake system containing an air purifier made with inlet and outlet pipes arranged horizontally and equipped with a process hatch on the side, a vertically placed air intake pipe, a pre-cleaner located in front of the air cleaner inlet, brackets fastenings to the car. The air purifier is connected to the inlet pipe with an intake pipe by means of a supply element of the pipeline and a flexible elastic sleeve. At the same time, the brackets for attaching the air cleaner to the car are installed on the upper part of the frame side member, and the air cleaner is fixed to the brackets with its lower part and is located above the car frame. The air intake pipe is fixed in the rear of the cab (patent CN 204532610 U, IPC B01K 13/02, F02M 35/02, F02M 35/10, publ. 05.08.2015).

A disadvantage of the known technical solution is that the air intake system occupies the space between the cabin and the loading platform, which generally reduces the useful cargo space of the car. The known system, although it includes corrugation, but when tipping the cab of a car, it is necessary to disconnect the elements of this system, which reduces its reliability during operation. In addition, the horizontal location of the outlet pipe reduces the reliability of the system, since during the maintenance of the vehicle, foreign objects and dust get on the elements in the direction in the direction of the purified air into the engine.

The task to which the proposed technical solution is directed is to improve the layout capabilities of the air intake device when located on a vehicle with a tipping cab, allowing the cargo platform / van to be located at a minimum distance from the cab, without compromising the efficiency and reliability of the air intake device.

To solve the problem in an air intake device containing an air purifier, made with a horizontally placed inlet pipe and a discharge pipe and provided with a process hatch, a vertically placed air intake pipe, while the air cleaner is connected to the inlet pipe with an air pipe through a pipe supply element and a flexible elastic sleeve, and with its outlet pipe - with a pipe for connecting to a turbocharger of the internal combustion engine by means of angular and straight elastic sleeves, a pre-cleaner located in front of the air cleaner inlet, car mount brackets, an air cleaner and an exhaust air pipe are placed vertically, with the outlet pipe facing up. In a particular case, the outlet pipe of the supply element of the pipeline is made with petals for connection with the supply pipe of the air purifier, the pre-cleaner is made in the form of a pocket-trap and a nipple valve connected to the pocket-trap located in the lower part of the supply element of the pipeline, the nozzles of the air intake pipe and the supply element of the pipeline have limiters and retaining flanges, and the technological hatch is placed with the possibility of opening it downwards, in addition, the pipeline for connecting to the turbocharger may have an air cleaner clogging sensor, a humidity sensor and a pipe for supplying purified air to vehicle systems.

The placement of the air cleaner and the exhaust pipe of the air cleaner vertically, with the exhaust pipe facing upward, made it possible to arrange the air intake device in such a way as to install it in front of and under the cab, and thereby free up the space between the cab and the cargo platform, which in general increases the useful cargo space a car. In addition, the reliability of the device is increased due to the fact that the vertical location of the outlet pipe up and the air purifier during maintenance of the vehicle eliminates the ingress of foreign objects and dust on the elements in the direction along the direction of the cleaned air into the engine, and the placement of the device in front of and under the cab allows tipping the cab to the device to remain integral, there is no need to disconnect its elements.

Thus, the combination of these features allowed to improve the layout capabilities of the air intake device when located on a vehicle with a tipping cab, allowing the cargo platform / van to be located at a minimum distance from the cab, without compromising the efficiency and reliability of the air intake device.

The claimed technical solution is illustrated by the drawings:

FIG. 1 - air intake device, a general view in isometric view;

справа;FIG. 2 - same view

on right;

FIG. 3 - air cleaner, left view;

FIG. 4 - air intake pipe with a protective grill at its entrance.

The air intake device contains a vertically mounted air cleaner 1, equipped with a process hatch 2, a vertically placed air intake pipe 3, an inertial pre-cleaner located in front of the air cleaner 1. The inlet pipe 4 of the air cleaner 1 is placed horizontally, and the outlet 5 is vertically and facing up. In this case, the air purifier 1 is connected by a supply pipe 4 to an air intake pipe 3 by means of a pipe supply element 6 and a flexible elastic sleeve 7, and by its discharge pipe 5 to a pipe 8 for connecting to a turbocharger 9 of an internal combustion engine by means of angular 10 and straight 11 elastic sleeves fixed using a tape clamp. The air cleaner 1 is equipped with a vertically arranged filter element (not shown) that performs the function of fine cleaning. The filter element may comprise a Z-shaped block filter material forming a pleated block filter material. A nipple valve 12 is provided in the lower part of the air cleaner 1 on the access door 2. The access door 2 for servicing the air cleaner 1, having the locking latches 13, opens downward.

The outlet pipe of the supply element 6 of the pipeline is made with petals 14 for connection with the supply pipe 4 of the air cleaner 1 by means of a tape clamp, while the petals, deforming under the action of the clamp, provide both immobility of the connection and tightness. In the supply element 6, the flow is rotated ninety degrees. The element 6 of the pipeline is equipped in the region of the above rotation with an inertial pre-cleaner made in the form of a pocket trap 15 and mounted on the pipe of the element 6 and connected with a pocket catcher 15, a nipple valve 16 for removing moisture and large mechanical particles from the incoming untreated atmospheric air to the inlet air purifier 1.

The air intake pipe 3 is connected to the pipe element 6, by means of a flexible elastic sleeve 7 secured using a tape clamp on the outlet and inlet pipes of the air intake pipe 3 and the pipe element 6, respectively. In this case, the nozzles of the air intake pipe 3 and the supply element 6 have limiters and retaining flanges for reliable connections of the system elements. The air intake pipe 3 is equipped at its inlet with a protective grill 17, which eliminates the ingress of foreign objects and large mechanical particles into the system.

The pipe 8 for connecting to a turbocharger 9 may have an air cleaner clogging sensor, a humidity sensor, and a pipe 18 for supplying purified air to the vehicle systems.

The air cleaner 1 is mounted on the chassis element of the car in front of the front wheel using the bracket 19, while the bracket 19 is fixed to the vertical wall of the frame side member, and the air cleaner 1 to the bracket 19 with its lateral side. The air intake pipe 3 is located in front of the tipping cab 20 below the windshield and is fixed to the cab 20 using the bracket 21. The pipe 8 for connecting to the turbocharger 9 of the internal combustion engine is mounted on the chassis using the bracket 22.

The air intake device operates as follows.

When the engine is running, atmospheric air is drawn into the air intake device through elements 3, 7, 6, where there is a preliminary effect on the air entering the device, namely preliminary separation of air from large mechanical particles and precipitation. Then, fine dust is separated in the air cleaner 1 and partially separated from moisture that has got into it, which is drained through the provided valve 12 in the wall of the air cleaner 1. The dust is deposited on the fine filter element. With clogging of the filter element of the air cleaner 1, the vacuum is significantly increased, which is diagnosed, and information about the state of the air cleaner 1 is displayed at the workplace of the car driver. This also indicates the need for maintenance of the air cleaner 1. When the internal combustion engine stops and there is no vacuum in the device, the nipple valves 16 and 12 open and accumulated mechanical particles and sediments are removed from the valves and, therefore, from the device itself.

To replace the filter element, it is not necessary to tilt the cab 20. It is necessary to open the process hatch 2 and remove the filter element from the air cleaner 1. At the same time, it is necessary, if necessary, to carefully remove the dust deposited on the inner surfaces of the air cleaner 1, excluding its getting to its exit. Moreover, for the maintenance of the device, the available location of the process hatch 2 on the air cleaner 1 is quite convenient.

For other routine maintenance work on the car, sometimes it is necessary to overturn the cab 20, while the separation of the elements of the device does not occur, the flexible elastic sleeve 7 is only bent, which helps to reduce the risk of foreign objects getting into the device during maintenance of the car.

The claimed technical solution allows to improve the layout capabilities of the air intake device when located on a vehicle with a tipping cab, allowing the cargo platform / van to be located at a minimum distance from the cab, without compromising the efficiency and reliability of the air intake device.

The claimed technical solution is possible for implementation on standard technological equipment using previously mastered technologies.
