A suspension device for a vehicle, including a spring-absorber unit constituted by a shock absorber and a suspension spring that are formed as one unit, the shock absorber including a cylindrical housing, a piston disposed in the housing, and a piston rod that is connected at a basal portion thereof to the piston and that extends from the housing, the suspension spring being a coil spring through which the shock absorber passes, wherein one end portion of the suspension spring is capable of being supported by the housing of the shock absorber, and the other end portion of the suspension spring is capable of being supported by a distal portion the piston rod of the shock absorber while the suspension spring is receiving a tensile load.

A vehicle suspension device, including: a carrier; a lower arm and an upper arm each of which is pivotally supported at one end portion thereof by a vehicle body, the other end portion of each of the lower arm and the upper arm being connected to the carrier; a rocking lever supported at one end portion thereof by the vehicle body so as to be rockable; a link one end portion of which is connected to the rocking lever and the other end portion of which is connected to one of the lower arm and the upper arm at a position between the one end portion and the other end portion of the one of the lower arm and the upper arm; and a shock absorber pivotally supported at one end portion thereof by the vehicle body, the other end portion thereof being connected to the rocking lever.

An autonomous vehicle and a suspension for the autonomous vehicle are provided. The suspension may include first and second support legs pivotally coupled to a body of the autonomous vehicle at respective pivot points, and extending in opposing directions to contact a surface upon which the autonomous vehicle moves. A biasing element biases the support legs towards the surface. A coupler couples the support legs to cause pivotal movement of one of the support legs to be mirrored in the other support leg. The coupler may cause the support legs to maintain a centerline, which extends equidistantly between the pivot points and through a sensor mounted to an underside of the body, perpendicular to the surface as the support legs pivot during movement of the autonomous vehicle.

The present invention relates to a suspension arrangement for a tracked vehicle. The suspension arrangement includes a road wheel arm having a wheel axle portion for supporting a wheel of the vehicle and a pivot axle portion. The road wheel arm is pivotably journalled at the pivot axle portion to a housing that is fixable to the vehicle body. A torsion bar is connected to the pivot axle portion and a torsion tube is arranged to be connected to the vehicle body, with the torsion bar running through the torsion tube and arranged to be connected to the torsion tube. The modulus of elasticity of the torsion tube material is lower than the modulus of elasticity of the torsion bar material such that the maximum suspension travel is increased.

A traction bar prevents rotation of an axle housing for a vehicle utilizing leaf springs. A traction bar has a rigid rail member having a first end and a second end. The traction bar also has a pivoting shackle member having a proximal end and a distal end. The proximal end of the shackle member is pivotally attached to the vehicle frame or to a vehicle frame bracket attached to the vehicle's frame. The distal end of the shackle member is pivotally attached to the first end of the rigid rail member. An axle bracket is pivotally attached to the second end of the rigid rail member. The three pivots provided with the traction bar provide for normal movement of the suspension without binding. However, upon acceleration or high torque load, the shackle member is thrust into axial alignment with the rigid rail member, stopping forward motion of the rigid rail member.
