Abstract

The invention relates to suspension design. The present vehicle suspension comprises a quadrangular frame. Each corner portion of the frame has a wheel block kinematically attached thereto so as to form two pairs of wheels—a front pair and a rear pair. On each side of the frame, longitudinal and transverse coupling cables are fastened for movement therealong inside housings. Each wheel block consists of a body that is simultaneously connected to two coupling cables. Movably mounted on the body are parallel horizontal arms, the first of which is fastened to the body by its middle portion. A knuckle with the hub of a wheel is attached to an end of the first arm and to another end of the second arm, and two coupling cable dampers are attached to the other end of the first arm. The housings of the cables are attached to the body of the corresponding wheel block. The free end of each cable is enclosed in a damper. Mounted on the cable end portions that freely project from the housings in front of a damper are spring stabilizers of the position of the wheel of the wheel block. Each coupling cable is provided with a linear actuator. The result is an increase in the stability and smoothness of movement of a vehicle.

Claims

1. A vehicle suspension comprising a quadrangular frame with a wheel block kinematically attached to each corner section thereof, thus forming two pairs of wheels—

front and rear ones, wherein the longitudinal and transverse coupling cables in housings, respectively, are attached to the sides of the frame so that they can move along the sides of the frame, each wheel block consists of a body connected with two coupling cables simultaneously, parallel horizontal arms are movably mounted on said body, the first arm is attached to the body with its middle part, a knuckle with a wheel hub is attached to one end of the first arm and other end of the second arm, two coupling cable dampers are attached to another end of the first arm, coupling cable housings are attached on the body of the corresponding wheel block, a free end of each cable is fixed in a damper, spring stabilizers of wheel position are put on end sections of cables protruding from the housings in front of the damper, and each coupling cable has a linear actuator, the casing of said linear actuator being rigidly attached to the body of the wheel block so that to allow changes in the relative position of the coupling cables housings and the body.

2. The vehicle suspension according to claim 1 wherein the suspension is supplemented with a U-shaped vertical frame, where its free ends are rigidly attached to the bodies of one pair of wheel blocks, while the U-shaped frame is pivotally connected to a handrail, kinematically coupled with blockers preventing wheel block arms movement.
