Abstract

For use in a motor vehicle for hindering (that is, reducing or completely preventing) lateral movement of the vehicle body relative to an axle of the vehicle by means of two members each connected to the vehicle body and to the axle, the members consist of an opposed pair of hydraulic piston and cylinder arrangements each disposed at an angle of less than 90* relative to the respective outboard portion of the axle, and there are respective hydraulic connections between the cylinder space behind the piston in each of the arrangements and the cylinder space in front of the piston in the other of the arrangements, such that in operation mutual pressure buildup in the cylinder spaces of the arrangements is effective to hinder lateral movements of the vehicle body relative to the axle, but the hydraulic piston and cylinder arrangements do not appreciably impede vertical movements of the vehicle body.

Claims

1. A device for hindering lateral movement of a motor vehicle body relative to an axle of the vehicle, comprising an opposed pair of hydraulic piston and cylinder arrangements each of which is connected to the vehicle body and to the axle and is disposed at an angle of less than 90* relative to the outboard portion of the axle, and respective hydraulic connections between the cylinder space behind the piston in each of the arrangements and the cylinder space in front of the piston in the other of the arrangements, such that in operation mutual pressure build up in the cylinder spaces of the arrangements is effective to hinder lateral movements of the vehicle body relative to the axle, but the hydraulic piston and cylinder arrangements do not appreciably impede vertical movements of the vehicle body.

2. A device for hindering lateral movement of a motor vehicle body relative to an axle of the vehicle, comprising an opposed pair of hydraulic piston and cylinder arrangements which are arranged symmetrically with respect to the longitudinal central plane of the vehicle and which are connected to respective points on the vehicle body and to a common point on a differential housing of the axle and are each disposed at an angle of less than 90* relative to the outboard portion of the axle, and respective hydraulic connections between the cylinder space behind the piston in each of the arrangements and the cylinder space in front of the piston in the other of the arrangements, such that in operation mutual pressure build up in the cylinder spaces of the arrangements is effective to hinder lateral movements of the vehicle body relative to the axle, but the hydraulic piston and cylinder arrangements do not appreciably impede vertical movements of the vehicle body.

3. A device for hindering lateral movement of a motor vehicle body relative to an axle of the vehicle, comprising an opposed pair of hydraulic piston and cylinder arrangements which are arranged symmetrically with respect to the longitudinal center plane of the vehicle and each of which is hingedly connected to the vehicle body and to the axle and is disposed at an angle of less than 45* relative to the outboard portion of the axle, and respective hydraulic connections between the cylinder space behind the piston in each of the arrangements and the cylinder space in front of the piston in the other of the arrangements, such that in operation mutual pressure build up in the cylinder spaces of the arrangements is effective to hinder lateral movements of the vehicle body relative to the axle, but the hydraulic piston and cylinder arrangements do not appreciably impede vertical movements of the vehicle body.

4. A device for hindering lateral movement of a motor vehicle body relative to an axle of the vehicle, comprising an opposed pair of hydraulic piston and cylinder arrangements which are arranged symmetrically with respect to the longitudinal center plane of the vehicle and are hingedly connected to respective points on the vehicle body and to a common point on the axle and are each disposed substantially parallel to the axle, and respective hydraulic connections between the cylinder space behind the piston in each of the arrangements and the cylinder space in front of the piston in the other of the arrangements, such that in operation mutual pressure build up in the cylinder spaces of the arrangements is effective to hinder lateral movements of the vehicle body relative to the axle, but the hydraulic piston and cylinder arrangements do not appreciably impede vertical movements of the vehicle body.

5. A motor vehicle comprising a body, a pair of steerable front wheels, a pair of rear wheels carried by outboard portions of a rigid rear axle that includes a differential housing, a pair of links which are rigidly connected at their rear ends to the rear axle and are hingedly connected at their front ends to the body, a pair of coil springs interposed between the rear axle and the body, and a device for hindering lateral movement of the body relative to the rear axle, the said device comprising an opposed pair of hydraulic piston and cylinder arrangements each of which is hingedly connected to respective points on the body and to a common point on the differential housing, and is disposed at an angle of less than 90* relative to the respective outboard portion of the axle, and respective hydraulic connections between the cylinder space behind the piston in each of the arrangements and the cylinder space in front of the piston in the other of the arrangements, such that in operation mutual pressure build up in the cylinder spaces of the arrangements is effective to hinder lateral movements of the vehicle body relative to the axle, but the hydraulic piston and cylinder arrangements do not appreciably impede vertical movements of the vehicle body.
