A socket joint having an offset housing configuration and reduced stud diameter can improve steering performance while being able to mate with standard vehicle components. In one implementation, the joint has an offset configuration along with a spherical bearing, where a central housing axis is radially offset from a central stud axis. With the offset configuration, the size of the stud is smaller than with typical joints. In one embodiment, a ratio of the housed stud diameter to the housing outer diameter is between 1:1.5 and 1:2.72. In some implementations, there is a transition surface between the housed stud portion and an attachment stud portion on the stud. One or more helical oil grooves may be located between the transition surface and a retaining ring groove. The retaining ring groove can be used to situate a retaining ring that holds the stud assembly together.

The invention relates to a connection system for connecting a damper unit of a vehicle inside a wheel suspension of the vehicle, the connection system having: an upper attachment region for attaching the damping unit, at least part of said region surrounding a receiving area for the damping unit and the receiving area extending around a first axis acting as the damping axis of the damping unit; a lower attachment region for coupling to the wheel-side portion of the wheel suspension, said lower attachment region having, in particular, two mutually spaced lower sections with an attachment area therebetween and an intermediate region which connects the upper attachment region to the lower attachment region. The main extension of the intermediate region corresponds to the direction of the first axis and the intermediate region allows the passage of a drive shaft of the vehicle. The connection system is made of an extruded part, the extrusion direction of which is the direction in which the extruded material extends, said material thus forming the intermediate region of the connection system. The invention also relates to a connection system comprising a clamping mechanism.

A vehicle suspension arm includes: a wheel support portion which supports a wheel through a ball joint serving as a joining member; a front side vehicle body installation portion serving as a vehicle body installation portion which is installed in a vehicle body; and a wheel side portion which joins the wheel support portion to the front side vehicle body installation portion. The wheel side portion includes an offset portion, which has a cross-sectional shape with a gravity center being offset upward or downward from a straight line that connects the ball joint to the front side vehicle body installation portion.

A vehicle suspension comprises a frame, a front axle and a rear axle and two L-shaped levers mounted on the frame. The axles are rigid or have independent suspension, or one is rigid and one has independent suspension. Each axle is attached movably to the frame by means of a bearing unit and two reactive tie rods. One end of each of the L-shaped levers is kinematically connected to the corresponding axle while the other ends are interconnected by a connecting tie rod. An increase in the stability of the suspension is achieved.

A suspension damping device installed at a chassis of a mobile robot comprises a vehicle frame, a controlling arm set and a damping device. The vehicle frame is fixed to the chassis and arranged on the ground. One end of the controlling arm set is hinged to the vehicle frame, and the other end of the controlling arm set is hinged to a steering device, so the controlling arm set controls the motion stability of the steering device. One end of the damping device opposite to the ground is hinged to the vehicle frame, and the other end of the damping device faced to the ground is hinged to the steering device. A six-wheeled bionic chassis which comprises a chassis frame, a controller, a sensor, front wheel suspension assemblies, middle wheel suspension assemblies and rear wheel suspension assemblies is also disclosed in the present invention.

A shock absorber device for a motor vehicle includes a spring support, a spring, a damping device configured to exert a damping force, a control unit, an electric motor electrically connected to the control unit and controllable by the control unit through a power supply signal emitted by the control unit, such that the electric motor provides a torque or a force corresponding to the power supply signal, and conversion means configured to control the damping device turning the torque or force outputted into a further force corresponding to the torque or force outputted and exerted by means of the damping device, wherein the control unit is configured to receive a first control signal indicative of a target value for the further force and to provide the power supply signal as a function of the first control signal, such that the power supply signal corresponds to the target value for the further force, the control unit being coupled to the spring support in a fixed position relative to the spring support.

In a vehicle equipped with an electric motor, a suspension device is provided for preventing a change in a behavior of the vehicle during use of regenerative brakes and friction brakes. A suspension device for a vehicle equipped with an electric motor for transmitting a drive force to the wheels via an output transmission shaft includes a suspension arm coupled to a vehicle body side and a wheel side, and which is capable of swinging in a vehicle up-down direction; and a damper which extends approximately perpendicular to a swinging axis in a vehicle body-side mounting portion of the suspension arm in a side view. The swinging axis of the suspension arm and an imaginary line perpendicular to a direction of extension of the damper are approximately parallel to each other in a side view.
