A suspension includes a jounce bumper, and a striker. A spring biases the knuckle toward a first position. One of the spring and the jounce bumper is disposed forward of a kingpin axis of the knuckle and the other of the spring and the jounce bumper is disposed rearward of the kingpin axis. When in a first position, the spring is a first spring length. When in a second position, the spring is shorter than in the first position and the jounce bumper contacts the striker. When in a third position, the spring is shorter than in the second position and the jounce bumper is compressed against the striker to be shorter than in the second position. When moving between the second and third positions, the spring and jounce bumper impart moments on the knuckle that approximately balance each other to maintain a desired caster angle.

A jig for assisting attachment and removal of a bolt, the bolt being inserted into a center hole of an inner cylinder included in a carrier bush and bolt holes opposed to each other to fasten a carrier and a lower arm, the bolt holes being provided in the lower arm, the jig having a base held in contact with a bottom surface of the lower arm, a fitting portion provided on the base to position the base with respect to the lower arm, and inner cylinder guides that are penetrable into an inner tip portion of the lower arm, and the inner cylinder guides have support grooves for supporting both ends of the inner cylinder, and a center line of the inner cylinder coincides with a center line of the bolt holes of the lower arm when the support grooves support the inner cylinder.

The invention relates to a single-shell spring control arm formed of sheet metal for a wheel suspension of a motor vehicle, with upwardly directed side limbs connected to one another by a base, with a first end section for connection to a chassis girder, with a second end section for wheel-side connection, with a spring receiving section, which is located between the two end sections and has a spring support surface formed on the base, and with a damper receiving section formed between the spring receiving section and the second end section for connecting a shock absorber. In order to achieve at relatively low component weight and favorable manufacturing costs improved stiffness with respect to high axle loads, the invention provides that a U-shaped constriction is formed between the spring support surface and the damper receiving section, which constriction extends in the base and in the side limbs.

A coilover shock absorber includes a damper element and a coil spring, where the coilover shock absorber includes a first mount for the damper element and a second mount for the damper element, and where the coilover shock absorber includes a first seat for the coil spring and a second seat for the coil spring, where the first mount for the damper element is operatively separate from the first seat for the coil spring, where the second mount for the damper element is operatively separate from the second seat for the coil spring. The resulting inverted coilover shock absorber allows for separate load paths for the damper element and the coil spring to the chassis.

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 towable off-road vehicle is provided with four-wheel independent suspension and an articulating tow bar, wherein an occupant is afforded rollover protection that allows them to be safely towed off road, yet empowering the occupant to follow the towed off-road vehicle with an independent suspension and steering system facilitated by an articulating tow bar for driving in the towing vehicle's tracks, thereby allowing more people to experience the excitement of off-roading first-hand.

Motor vehicle control arm (1) comprising two profiles (2, 3) made from a metallic material, which are arranged at a distance opposite each other, and are connected to at least one plastic element (11) made from a fiber-reinforced plastic, wherein a plastic element (11) is designed in particular as a spring seat, which is designed to accommodate a motor vehicle spring.

Such a motor vehicle control arm (1) is optimized with respect to weight and costs.

A control arm for a wheel suspension of a motor vehicle. The control arm including a base body having a spring seat for receiving a helical spring of the wheel suspension. The control arm having a first end region connected to a spring-loaded component of the motor vehicle and a second end region connected to an unsprung component of the motor vehicle. The base body includes a first partial shell composed of steel and a second partial shell composed of a composite material, the shells undetachably fixedly connected to one another at least in one region of the spring seat.

A vehicle weight measurement device includes a moving body, an attachment body, a stopper ring provided between the moving body and the attachment body, and a rotation prevention part configured to prevent the moving body and the attachment body from rotating relative to each other. The stopper ring includes a fixing part fixed to one of the moving body and the attachment body and a separation and detachment prevention part provided at the other of the moving body and the attachment body and configured to prevent the moving body and the attachment body from separating and detaching, without inhibiting movement of the moving body. The rotation prevention part includes a pin fitted from the moving body to the attachment body.

The present invention relates to an active suspension system allowing the force acting axis of a spring to be controlled, wherein a control means for the force acting axis of a spring is installed either between an upper seat plate and an upper arm, or between a lower seat plate and a lower arm so as to allow the wheel rate and vehicle height to be controlled by varying the force acting axis of the coil spring, and a manipulation unit capable of controlling the operation of the control means for the force acting axis of a spring is installed inside the vehicle. By varying the force acting axis of the coil spring, the present invention can significantly improve the marketability of the suspension system and reliability of the vehicle by varying the ride quality.
