Description

This invention relates to vehicle wheel suspensions, in particular, to steering wheel suspensions.

The purpose of the invention is to extend the functionality of the suspension.

The drawing shows the suspension, the overall appearance.

The suspension of the steerable vehicle wheel includes a housing 1 with a cover 2 mounted on the frame 3 of the vehicle. A piston 4 with internal 5 and external 6 rods is installed in the cavity of the housing. In the bottom of the housing there is a hole 7 for supplying fluid (compressed air or liquid under pressure) from the control system (not shown). A lid 8 is mounted on the lid 2 of the housing 1. The inner rod 5 is hollow, has splined grooves 9 and is interconnected with relative possibility with the splined shaft 10. The splined shaft 10 is located inside the glass and rigidly fastened to the shaft 11 of the hydraulic motor 12 installed on the outer end of the cup 8. In the cavity of the housing 1, under the cover 2, there is a bearing 13, which allows the inner rod 5 to rotate around the axis, and the bearing washer 14, is pressed against the bearing 13 by means of a conical spring 15 located between the piston 4 and the support plate 14. The outer rod 6 is connected to a fork 16, in the cheeks 17 of which a wheel 19 is mounted on bearings 18. On the outside of one of the cheeks 17 a hydraulic motor 20 is located 20. The shaft 21 of the hydraulic motor 20 is rigidly connected to the axis 22 of the wheel 19. The hydraulic motor 20 serves as an autonomous rotation of the wheel 19. The hydraulic motor 12 serves to autonomously rotate the wheel 19 in the horizontal plane.

Self-propelled vehicle is equipped with a control system that provides synchronous or autonomous movement of the wheels 19. When the wheel 19 hits the sloping

A coil spring 15. The inner rod 5 thus freely slides along the splined shaft 10. The amount of compression of the spring 15 is determined by the height of the obstacle to be overcome. When the wheel 19 is removed from the obstacle, the piston 4 is lowered together with shtochki 5 and 6, connected by a fork 16 with a wheel 19, which occurs under the action of the force of the spring 15.

To overcome the vertical obstacle, pressurized fluid is delivered through the opening 7 into the body 1 under the piston 4. Porschen 4 together with rods 5 and 6 and respectively with the wheel 19 moves upward, compressing the spring 15. The rod 5 moves along the spline shaft 10. The movement of the piston is designed to overcome obstacles that are higher than the diameter of the wheel 19.

In each particular case, the flow of fluid under the gap 4 is carried out until the moment when the wheel 19 can be freely transferred over the obstacle, after which the fluid through the opening 7 in the housing 1 returns to the distribution system. Porshchen 4 together with the rods 5 and 6 is moved down by the action of the spring 15 until the wheel 19 is lowered onto the supporting surface.

To change the direction of movement of the vehicle, the wheels 19 are turned either with the vehicle moving or with the vehicle stationary. The rotation of the wheels 19 occurs when the hydraulic motor 12 is disconnected from the control system (not shown). From the shaft 11 of the motor 12, the rotation is transmitted to the slider shaft 10. Through the slit joint, the inner brush 5 is rotated together with the piston 4, the outer brush 6, the fork 16 and the wheel 19. When the wheels 19 are turned at the required angle, the hydraulic motor 12 is turned off. In order to increase vehicle throughput, the wheels are forced to rotate 19. The hydraulic motor 20 is activated from the control system. The rotation of the motor shaft 21 is transmitted to the axis 22 of the wheel 19.
