A wheel securing axle includes a shaft that includes a first end portion, a second end portion including a thread, and a shaft axis, a washer rotationally supported by the first end portion of the shaft, and a click mechanism arranged between the shaft and the washer.

A wheel-mounting assembly for a utility vehicle includes a chassis and a wheel support assembly mounted to respective outboard ends of first and second telescopic axle assemblies. The first and second telescopic axle assemblies are laterally spaced from one another and are each secured to the chassis. The first and second telescopic axle assemblies each include a respective actuator arranged to control extension and retraction thereof for steering and track-width control.

A vehicle includes a chassis, an axle pivotally coupled to the chassis such that the axle can tilt from side to side relative to the chassis, a tilt-angle sensor configured to detect a tilt angle of the axle relative to the chassis, and steerable hubs carried by the axle. Each hub is configured to rotate about steering axes relative to the axle, and a steering-angle sensor is configured to detect a steering angle of at least one hub relative to the axle. A control system limits a maximum steering angle of the hubs based at least in part on a size of tires or tracks carried by the steerable hubs and the detected tilt angle of the axle. A method includes detecting a tilt angle of the axle relative to the chassis and limiting the maximum steering angle of the hubs.

A vehicle system includes an axle arrangement operably coupling a wheel assembly with a frame. The frame defines a fore-aft axis and a transverse axis extending generally transverse to the fore-aft axis. The axle arrangement includes first and second axle elements adapted for operative connection between the frame and the wheel assembly for extension and retraction along the transverse axis. The first axle element can be operably coupled with the frame and the second axle element can be integrated with the wheel assembly. One or more sensors can be configured to generate vehicle dat. A computing system can be configured to receive an input related to an adjustment to the position of the second axle element relative to the fore-aft axis and generate an adjustment model based at least partially on the input and the vehicle data.
