Abstract: An independent wheel suspension for a two-track vehicle has a wheel carrier, a vibration damper designed and arranged in the manner of a damper strut, and a leaf spring element, which has, in particular, a fiber composite material or is made from a fiber composite material. The leaf spring element is oriented at least approximately in the transverse direction of the vehicle and is designed to provide a suspension function and, together with the vibration damper, to guide a vehicle wheel fastened to the wheel carrier when the independent wheel suspension is installed in a vehicle for functional usage. The leaf spring element is connected, on the wheel carrier end, to the wheel carrier via two rubber bearings, each having a bearing axis and a central bearing point, so as to be rotatable about the respective bearing axis of each rubber bearing and is designed to be connected, on the vehicle body end, to an axle support in a torsion-resistant manner and/or directly to a vehicle body.

Abstract: A leaf spring bearing for supporting a leaf spring against a transportation vehicle body having a body-side coupling portion and at least one elastomer portion for compensating displacements transverse to the supporting direction. A centering apparatus for interlockingly engaging with a vehicle-body-side counter-contour is provided on the coupling portion. The centering apparatus on the coupling portion guides the coupling portion of the leaf spring bearing in the event of deviations from a target contact position on the transportation vehicle body transverse to the supporting direction, toward the target contact position. Also disclosed is a transportation vehicle wheel suspension having the disclosed leaf spring bearing and an assembly method.

Abstract: An electric vehicle includes a suspension and powertrain unit having a vehicle frame module, an electric motor unit carried by the frame module centrally between two wheels and a suspension including, for each wheel, an upper oscillating arm and a lower oscillating arm carrying a respective wheel support. Each wheel support rotatably supports a respective wheel hub connected to the electric motor unit by a respective drive shaft. Brake discs are mounted on two output shafts of the electric motor unit, at a distance from the respective wheels, and are connected by drive shafts to the hubs of the two wheels. Thanks to the absence of brake discs adjacent to the wheel hubs, swivel joints connecting each wheel support to the respective upper and lower arms can be arranged so as to define a steering axis passing through a respective wheel center and thereby having a substantially zero kingpin offset.

Abstract: A front suspension lift kit for a golf cart includes a kingpin sleeve and a kingpin. The kingpin is configured to extend through both the kingpin sleeve and a steering knuckle of the golf cart. A frame spacer is mountable to a frame of the golf cart, and a leaf spring is mountable to the frame spacer. The frame spacer is configured for positioning the leaf spring such that the leaf spring is spaced from the frame of the golf cart when the frame spacer is mounted to the frame of the golf cart and when the leaf spring is mounted to the frame spacer.
