A spindle for a wheel end assembly includes a first end of the spindle receiving the wheel of a vehicle on a first side of in the wheel end assembly, and a second end of the spindle defining a flange and receiving the axle of a vehicle is disclosed. The flange includes a socket joint that receives the axle on the second side of the wheel end assembly. Mounting members extend distally from the second side a first distance to secure the spindle to the wheel end assembly via the flange. The socket joint of the spindle extends from the second side of the wheel end assembly a second distance from the second side. The second distance is greater than the first distance. A third distance represents degree of overlap of the axle by a ratio with respect to the outer diameter of the axle ranging from 8% to 20%.

An axle system includes an axle stub, a first connecting section and a second connecting section, wherein the axle stub is embodied on its outer side so as to be essentially rotationally symmetrical about a stub axis and has two ducts which extend parallel to the stub axis in certain regions, wherein the connecting sections lie in a connecting plane which is oriented orthogonally with respect to the stub axis, wherein the axle stub has an attachment region for securing a brake carrier which extends parallel to the connecting plane.

A non-driven axle for a vehicle or a trailer is provided. The non-driven axle includes a first arm portion, a second arm portion, and a central portion. The first arm portion is for rotatably mounting a first wheel hub. The second arm portion is for rotatably mounting a second wheel hub. The second arm portion is on an axial end of the central portion opposite the first arm portion. The central portion is between the first arm portion and the second arm portion and may be substantially U-shaped or substantially ring-shaped. The substantially U-shaped central portion includes a main portion and a radially inner portion. The substantially ring-shaped central portion includes a main portion and an inner portion. The non-driven axle reduces a weight of a vehicle or trailer while capable of being lifted without interfering with an operation of a drive axle.

A replacement spindle that can be easily removed for service or replacement. The spindle may have a threaded projection corresponding to a threaded bushing, which may be secured within an axle tube. The spindle may be screwed into place for use, then unscrewed for service or replacement.

An internally threaded axle tube and spindle assembly, where the spindle can be easily removed for service or replacement. The spindle may have a threaded projection corresponding to the internal threads in the axle tube. The spindle may be screwed into place for use, then unscrewed for service or replacement.

Detachable adjustable-width motor assemblies. Some embodiments may be configured for retrofitting between two legs of a golf cart. Some embodiments may comprise a motor housing having a first motor disposed within the motor housing, a first drive shaft, and a second motor disposed within the motor housing having a second drive shaft. The assembly may further comprise a first housing mount configured to be connected to the first wheel leg and a second housing mount configured to be connected to the second wheel leg. The first housing mount and/or the second housing mount may be concentrically and/or slideably engaged with the motor housing and configured to adjust the width of the motor assembly. The first drive shaft may be configured to engage with and transmit torque to the first wheel and the second drive shaft may be configured to engage with and transmit torque to the second wheel.

A suspension for a wheeled vehicle include an axle with a mid-section and an end comprising an upper portion and a lower portion defining a space therebetween, a leaf spring having forward and rear ends attached to vehicle structure and a mid-section retained in the space and secured between the upper and lower portions, and a closure element attached to the axle end and at least partially closing an outboard end of the space. The upper and lower axle portions may be formed integrally with the axle mid-section or may be a separately-formed component secured to the axle. The space tapers from a greater vertical dimension at the outboard end thereof to a smaller vertical dimension at an inboard end thereof, and the leaf spring mid-section is wedged into the space. An intermediate element is disposed between the mid-section and at least one of the upper and lower axle portions.
