Abstract

The invention relates to the field of automotive industry, mainly to especially heavy-duty trucks. When a vehicle is moving, forces arise that create bending moments in the longitudinal vertical plane, as well as torques relative to the longitudinal axes of the frame, which causes spatial distortion of the frame and body. The purpose of the invention is to reduce material consumption due to the reduction of the actual loads. This is achieved due to the presence in the area of the front axle of an additional support for the body, which allows for longitudinal displacement, and in the area of the rear axle of two coaxial articulated supports located on the turntable. In addition, the hinged connection of the frame is made with the possibility of rotation relative to the longitudinal axis, and the cylinder of the tilting mechanism with two ball bearings is installed in the zone of the front axis. The swiveling g platform has a blocking device for turning the body relative to the frame when the body is raised and lowered. 1 h. item f-ly, 2 ill. (L

WITH

The invention relates to the automotive industry, mainly to especially heavy-duty trucks.

The purpose of the invention is to reduce material consumption by reducing the existing loads.

FIG. 1 shows a vehicle, side view; in fig. 2 - the same in terms of.

The spherical hinge 1 of the freight turn of the vehicle passes through points close to the middle of the front and rear axles, which increases the stability of the vehicle when turning and provides constant protection for the driver's cab with the visor of the platform.

When a vehicle is moving on a rough road, the difference in the angular displacements of frame elements 8 and 9 does not cause

the vehicle's body (body) 2 forms of their elastic deformations, which are compensated for on a support that allows them to be pushed through by the hinge 10, which has an additional degree of freedom in the direction of turns around the longitudinal axis. Wherein

Longitudinal movements of a spherical joint 1, for example, on a movable support 3 fixed to axis 4. Rear supports 5

cargo platform (body) does not interfere

the cargo platform (body) through two angular movements of the frame by means of the angular-axis transverse joint 6 is supported on the rotary platform 7.

Front and rear elements 8 and 9 of the frame are interconnected by a hinge 10, which has one degree of freedom in the right; 1 turns around the vertical 20 axis and may have an additional degree of freedom in the direction of turns around the nano axis.

The cylinder of the tilting mechanism 11 is connected in the zone of the front axle with the MeirroM 8 frame and the cargo platform (body) with 2 ball bearings 12.

The locking device of the turntable 7 can be made in various ways, for example, in the form of friction

the displacements of the spherical hinge 1, its longitudinal movements relative to the frame, for example, due to the movements of the support 3, as well as the angular displacements of the turntable 7 and the hinges 6. As a result, the frame elements are not subjected to twisting loads.

When a vehicle is used as a rear dump truck, installing a tipping mechanism 11 with two ball bearings 12 in the area of the front axle of the cylinder 25 reduces bending loads on the frame elements and their articulation when lifting and lowering the loading platform (body). Lateral stability of the cargo truck or in the form of 30 forms (body) and vehicle rigidly connected

with supports 5 protrusions 13 entering the slots of the base of the turntable 7 and so on. II.

Due to the fact that the load platform (body) rests on the frame elements in the zones of the front and rear axle, the loads on the frame elements and their hinge connection are reduced.

Since the load platform (body) rests on three points, it does not undergo steep loads during angular movements.

When the vehicle is rotated, the location of the attachment points of the front and rear supports of the loading platform (body) on the frame and spacing elements is changed.

when raising and lowering the cargo platform (body), it is provided with a device for locking the turntable 7 relative to the frame.

Claims (2)

Claim 1. Articulated vehicle comprising a pivotally articulated frame, front and rear axles with wheels, a loading platform fixed to the frame in the rear axle area with the possibility of rotation in a vertical plane, a platform lifting cylinder, characterized in that, in order to reduce the material Tanks by reducing the effective loads between the frame and the body are installed in the zone between them, while the relative 45 of the front axle of the support frame, and in the rear zone, the location of the attachment points of the supports on the load platform (body) remains unchanged. The inconsistency between the attachment points of the supports of the loading platform (the frame and the load platform (body the call is compensated by the angular displacements of the spherical hinge 1, its longitudinal slit relative to the frame, for example, by the displacements of the support 3, axles - two hinged bearings located on the same transverse axis on the turntable, the frame joint hinge is designed to rotate relative to the longitudinal axis of the vehicle, while the hydraulic cylinder is made with two ball ends at the ends and is mounted to one of them on the frame in the front area axis. 2. The vehicle of claim 1, the moment of turning the vehicle passes through points close to the middle of the front and rear axles, which increases the stability of the vehicle when turning and provides permanent protection for the driver’s cab with the visor of the platform. When a vehicle is moving on a rough road, the difference in the angular displacements of frame elements 8 and 9 does not cause their elastic deformations, which are compensated by the hinge 10, which has an additional degree of freedom in the direction of turns around the longitudinal axis. Wherein cargo platform (body) does not interfere angular displacement .m frame due to the angle the displacements of the spherical hinge 1, its longitudinal movements relative to the frame, for example, due to the movements of the support 3, as well as the angular displacements of the turntable 7 and the hinges 6. As a result, the frame elements are not subjected to twisting loads. When a vehicle is used as a rear-dump truck, the bending loads on the frame elements and their swivel connection when lifting and lowering the loading platform (body) are reduced by installing a tipping mechanism 11 with two ball bearings 12 in the front axle area of the cylinder. Side load stability when raising and lowering the cargo platform (body), it is provided with a device for locking the turntable 7 relative to the frame. Claim 1. Articulated vehicle comprising a pivotally articulated frame, front and rear axles with wheels, a loading platform fixed to the frame in the rear axle area with the possibility of rotation in a vertical plane, a platform lifting cylinder, characterized in that, in order to reduce the material Tanks by reducing the effective loads between the frame and the body are installed in the zone front axle frame support, and in the back front axle frame support, and in the back axles - two hinged bearings located on the same transverse axis on the turntable, the frame joint hinge is designed to rotate relative to the longitudinal axis of the vehicle, while the hydraulic cylinder is made with two ball ends at the ends and is mounted to one of them on the frame in the front area axis. 2. Vehicle under item 1, dated and also due to angular displacement. 55 is characterized by turning the pad company platform 7.
