Description

FIELD OF TECHNOLOGY

The utility model relates to vehicle suspensions, in particular to hydraulic suspensions of trackless vehicles - trailers, trucks and cars.

BACKGROUND

Known hydropneumatic suspension disclosed in SU 1791167 A1, publ. 01/30/1993 for a vehicle containing a hydraulic cylinder, the cavities of which are formed by a piston connected to the suspension arm and filled with liquid, are connected to a pressure source, a pneumatic spring, divided by a diaphragm into a pneumatic chamber, connected through a valve to a gas pressure source, and a hydraulic chamber connected by a valve with a hydraulic cylinder, a block of pressure sensors, a pump installation, a tank with a working fluid.

The disadvantage of this suspension is the design complexity.

The closest technical solution is the hydraulic suspension disclosed in SU 990551 A1, publ. 01/23/1983 The hydraulic suspension of the vehicle contains hydraulically interconnected hydraulic cylinders, each of which is mounted between the support and the body of the vehicle, and a hydraulic control system including a roll sensor, a differential pressure sensor and hydraulic pumps.

The disadvantages of such suspensions include the impossibility of the simultaneous summation of all disturbing forces in a single regulatory body and the exclusion of the effects of efforts on the car frame.

DISCLOSURE OF USEFUL MODEL

The objective of the claimed utility model is to create a suspension of a simple, compact design with high elastic characteristics, with great adjustment of clearance and lifting force.

The technical result of the claimed utility model is to improve operational properties by creating the possibility of a controlled change in clearance.

The specified technical result is achieved due to the fact that the hydraulic suspension of the vehicle’s wheel contains upper and lower movable levers pivotally mounted with a suspension strut, and with a vehicle supporting frame, a hydraulic cylinder pivotally mounted with an upper movable lever and with a vehicle supporting frame.

The upper movable lever of the hydraulic suspension is made with an eye.

BRIEF DESCRIPTION OF THE DRAWINGS

The utility model will be more clear from the description, which is not restrictive and is given with reference to the accompanying drawings, which depict:

FIG. 1 - Hydraulic suspension of a single-axle trailer.

FIG. 2 - Hydraulic suspension of a biaxial trailer.

1 - lower movable lever; 2 - upper movable lever; 3 - depreciation rack; 4 - a hydraulic cylinder; 5 - high pressure hoses; 6 - hydroelectric power station; 7 - battery; 8 - control panel; 9 - an eye; 10 - supporting frame; 11 - the body.

IMPLEMENTATION OF A USEFUL MODEL

The hydraulic suspension of the vehicle’s wheel contains the upper (1) and lower (2) movable levers pivotally mounted to the suspension strut (3) and to the bottom of the vehicle’s support frame (10), a hydraulic cylinder (4) pivotally mounted to the upper (2) movable lever and with the upper part of the supporting frame (10) of the vehicle.

The upper (2) movable lever of the hydraulic suspension is made with an eye (9), which provides rigid fastening of the hydraulic suspension with a bolt to the supporting frame (10) in order to relieve pressure from the hydraulic cylinder (4) during long-term transportation of the vehicle.

The cushioning strut (3) contains a reinforced spring, which provides an increase in the chest suspension, which ensures an increase in the value of the vibrations (which the suspension can extinguish) of the carrier frame arising from the action of the road.

Adjustment of vehicle clearance is as follows.

Using the control panel (8), a command is sent to the hydroelectric power station (6) located in the vehicle body (11) to create pressure in the hydraulic cylinder, as a result, the working fluid pressure is created on the hydraulic cylinder rod (4) due to the fact that the working fluid from hydroelectric power stations (6) through high pressure hoses enters the hydraulic cylinder (4). The resulting pressure of the working fluid on the hydraulic cylinder rod (4) lowers the upper (1) and lower (2) movable levers pivotally due to the extension of the rod from the hydraulic cylinder (4), resulting in increased vehicle clearance. A command is sent from the control panel to the hydroelectric power station (6) to relieve pressure from the hydraulic cylinder (4), as a result of which the hydraulic cylinder returns to its original position and the vehicle’s ground clearance is reduced. Creating a different pressure in the hydraulic cylinder allows you to get a different value of the clearance of the vehicle. The operation of the hydraulic cylinder (4) is carried out using a battery (7) located in the body (11) of the vehicle.

The overall suspension design is designed so that all components are accessible and maintainable.

Thus, the claimed design provides the suspension of a compact design, to increase operational properties (the duration of operation of the suspension, the possibility of increasing clearance) and the elastic characteristics (vibration values that are damped by the suspension) of the vehicle suspension.

A utility model has been disclosed above with reference to a specific embodiment. For specialists, other embodiments of the utility model that do not change its essence, as disclosed in the present description, may be obvious. Accordingly, a utility model should be considered limited in scope only below by the following claims.

Claims (2)

1. Hydraulic suspension of a vehicle wheel, comprising upper and lower movable levers pivotally mounted with a suspension strut and with a vehicle carrier frame, a hydraulic cylinder articulated with an upper movable lever and with a vehicle carrier frame. 2. The hydraulic suspension according to claim 1, characterized in that the upper movable arm is made with an eye.
