A damping system of a two-track vehicle includes a passive stabilizer having a torsion bar which runs in a vehicle transverse direction and having lever elements which adjoin the torsion bar at the end sides and which are connected to mutually oppositely situated wheel suspension arrangements of an axle of the vehicle. Two actuators are assigned to respective wheels of the wheel suspension arrangements and are mounted on the vehicle body. Each actuator has a drive by way of which a torque can be exerted on that section of the stabilizer which faces toward the respective wheel. Here, the actuators are in the form of electric motors and are designed to dampen vertical vibrations of the respective wheel or of the so-called unsprung mass, and/or vibrations of the vehicle body in a frequency range between 0 Hertz and at least 20 Hertz, through suitable regulation of the drive of the actuators and thus also through active introduction of forces into the system.

Provided is a robotic device including: a body; an electronic computing device housed within the body; and at least two wheel suspension systems coupled with the body including: a first suspension system including: a frame; a rotating arm pivotally coupled to the frame on a first end and coupled to a wheel on a second end; and an extension spring coupled with the rotating arm on a third end and the frame on a fourth end, wherein the extension spring is extended when the wheel is retracted; and a second suspension system including: a base slidingly coupled with the frame; a plurality of vertically positioned extension springs coupled with the frame on a fifth end and the base on a sixth end; at least one set of paired magnets, with at least one magnet affixed to the frame and paired to at least one magnet affixed to the base.

A vehicle includes: N (N is an integer equal to or larger than 3) wheels including a pair of wheels spaced apart from each other in a width direction of the vehicle and a steered wheel turnable to right and left relative to the vehicle body; operation input unit to be operated to input a steering direction of the steered wheel; lean mechanism for leaning the vehicle body in its width direction; and lean control unit for controlling the lean mechanism. Lean control unit controls the lean mechanism so that vehicle body leans toward the steering direction side in response to an input into the operation input unit. Vehicle includes detector for detecting a force that changes a lean angle of the vehicle body. Lean control unit causes the lean mechanism to generate a torque that produces a force in a direction opposite to a force detected by the detector.

Embodiments of the present invention describe a recreational vehicle spindle, including a spindle body having one or more sockets in the spindle body, and an upper attachment mechanism in contact with the spindle body and adapted to attach to a steering component. The spindle also includes a lower attachment mechanism in contact with the spindle body and adapted to attach to a ski or wheel. The one or more sockets are adapted to each receive a ball and stud forming one or more ball joints.

A trailing arm mounting bracket for connecting a trailing arm to a vehicle body includes: a fixing portion fixed to the vehicle body, a first connection plate and a second connection plate each extending from opposite ends of the fixing portion to support opposite ends of a mounting bush of the trailing arm and to which a fastening bolt fastened to the mounting bush is coupled, a first reinforcement portion to connect and reinforce the portions where the first and second connection plates and the fixing portion are connected with a truss structure, and a second reinforcement portion to connect and reinforce the first connection plate and the second connection plate at a position in the front of the mounting bush.

A suspension interconnection assembly for a vehicle adapted to move along a surface of the ground includes an axle housing and a spring seat. The spring seat includes a pocket defined by a U-shaped saddle having a bottom wall that extends between a first leg and a second leg. The first and second legs include claw portions that are adapted to engage an upper portion of the axle housing. Welds secure the first and second claw portions to the axle housing so that areas of the axle housing adjacent the welds are in a state of residual tensile stress based on forming. The position of the welds provides a stress cancelling effect upon application of the load to the axle housing in a direction perpendicular to the surface of the ground.

Strut-Pressed Bar to be installed to the suspension of the car composed of two Moaatmg-Flates cut into round shape with the circular shape hole at the center that is big enough to allow the exposure of the tip of the shock-sbsorber shaft. At the rim, the holes will be drilled at the point that is match to the position of the existing bolt on the top caps of the strut-assembly to be fixed to each other. On top of the Mounting-Plate was welded with the U-shape steel plate with 2 holes drilled at the base of the II and both 2 wings extend through the rim of the mounting plate to round the tip of the shock, absorber-shaft in the middle. The strut-bar made of flat aluminium bar bended into the bird-wing shape or stretch letter M, at both ends were vertically welded with the aluminium plate with 2 holes drilled to be mounted tp the die U-shape on the Mounting-Plates

A variable gauge train control device comprises an inverter, a location detector, and a torque calculator. The inverter collectively controls torques of main electric motors. The location detector detects an entry into a gauge changeover section. The torque calculator, upon detection by the location detector of the entry into the gauge changeover section, suspends idling control that otherwise restricts the torques of the main electric motors and calculates a first torque pattern for making the inverter operate in accordance with the torques of the main electric motors.

A torsion beam of a vehicle torsion beam suspension has a closed cross section. A beam center portion has an inverse substantially v-shaped cross section or a substantially v-shaped cross section. Circumference increasing portions having a longer circumferential length toward the beam ends are disposed at opposite sides of the beam center portion. Each circumference increasing portion has a beam width that is a width in the fore and aft direction of a vehicle body, the beam width gradually increasing toward a beam end, and increasing at a higher rate as a position of the beam width is closer to the beam end.
