A land vehicle includes a frame structure, a plurality of wheels, and an impact management system. The frame structure includes an operator cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the operator cage in a longitudinal direction. The frame structure includes a pair of rails that each extends in the longitudinal direction from a first end arranged adjacent a pair of front wheels to a second end arranged adjacent a pair of rear wheels. The plurality of wheels are supported by the frame structure. The plurality of wheels includes the pair of front wheels and the pair of rear wheels. The pair of front wheels are positioned forward of the pair of rear wheels in the longitudinal direction.

There is provided a patient transport apparatus. The apparatus includes a height-adjustable assembly having a longitudinal axis. The apparatus includes a brake cable. The brake cable includes an elongate portion extending along the height-adjustable assembly and includes a slack portion. The apparatus includes a brake cable housing coupled to and axially offset from the height-adjustable assembly. The slack portion of the brake cable is enclosed within a hollow interior of the brake cable housing.

A torque tube for a brake assembly may include a tube portion having a first centerline axis, a conical back-leg portion extending from the tube portion in a radially outward angled orientation relative to the first centerline axis, and a lip portion disposed at a radially outward end of the conical back-leg portion. The lip portion may have added structural material to improve the structural properties of the torque tube to prevent or mitigate damage that would otherwise be caused by friction-induced vibrations.

A suspension for a motor vehicle includes at least one internally hollow suspension arm, so as to define at least one inner cavity, and is characterized by comprising at least one duct extending along the inner cavity between an input hole of the suspension arm and an output hole of the suspension arm, the duct being designed to allow a fluid flow or an electric wiring to go from the input hole to the output hole through the inner cavity.

An impact absorbing mechanism for a wheel is provided. The mechanism has discs that are engaged so that rotation of a first disc causes translational movement of a second disc. A restraining member such as a spring acts against translational movement of the second disc to absorb energy from a head on collision or aggressive braking. Once the mechanism is fully activated, teeth on the first and second discs engage to prevent kick back from the restraining member. In some embodiments, a ratchet mechanism is provided to prevent kick back from the restraining member even when the impact absorbing mechanism is not fully activated.

A mining machine including a bi-directional electrical bus, a power source coupled to the bi-directional electrical bus, a motor coupled to the bi-directional electrical bus, the motor powered by energy available on the bi-directional electrical bus, a kinetic energy storage system coupled to the bi-directional electrical bus and a controller. The controller is configured to communicate with the kinetic energy storage system and the power source. Wherein the controller is configured to operate the kinetic energy storage system as a primary power source for the bi-directional electrical bus and to operate the power source as a secondary power source for the bi-directional electrical bus when the kinetic energy storage system cannot satisfy an energy demand on the bi-directional electrical bus.

A dig system which allows for a vehicle to perform a dig maneuver, without sacrificing drivability. An actuator places the dig system in one of four different modes of operation, where the front wheels are placed in either a first configuration or a second configuration, where the front wheels are positioned at a desired steering angle, and one of the front or rear wheels is braked and prevented from rotating. The transfer case transfers power to one or more of the non-braked wheels, and disconnects from the remaining wheels. One or more of the non-braked wheels are rotated such that the vehicle pivots about an axis which extends through one of the wheels. One of the rear wheels is braked when performing a front dig maneuver, and one of the front wheels is be braked when performing a reverse dig maneuver.
