A hub directly driven by a motor and used for a heavy-duty chassis dynamometer includes a hub body, wherein a mounting surface is arranged on an inner circumference of the hub body and is disposed around a transmission shaft coaxial with the hub body, the transmission shaft is sleeved with a driving assembly, and bearing assemblies are disposed on two sides of the driving assembly in an axial direction respectively; a plurality of axial mounting plates are disposed on an outer circumference of the driving assembly, and tension sensor assemblies are connected to the axial mounting plates located outside the hub body and are mounted on the support frame; and an end, away from the mounting surface, of the transmission shaft, is sleeved with an end flange plate, and a plurality of brake assemblies are disposed on the end flange plate and are mounted on the support frame.

A brake system and a method of performing a release operation with the brake system. The brake system comprises a sliding caliper body and a fixed caliper body. The fixed caliper body has a stop formed therein and accommodates a spindle nut that mates with the stop in a release operation. The brake system comprises a spindle that drives the spindle nut in a second direction during the release operation. Continued translation of the spindle after mating of the spindle nut with the stop drives the sliding caliper body in a first direction opposing the second direction.

A brake assembly includes a brake disc in rotational engagement with a wheel of a vehicle, a brake pad which frictionally engages the brake disc in a dynamic braking operation and a parking brake operation, a dynamic actuator adapted to bring the brake pad and brake disc into the frictional engagement in the dynamic braking operation, and a parking brake actuator associated with the dynamic actuator such that, in the parking brake operation, the frictional engagement of the brake disc and brake pad is maintained.

A caliper body for a disc brake having at least one thrust housing. The housing has a housing bottom wall and a housing lead-in edge portion. The housing lead-in edge portion has at least one housing edge surface. At least either a first elongated element caliper inner side or a second elongated element caliper inner side has at least one groove bottom wall and groove sides which delimit at least one groove. The at least one groove bottom wall is axially outer with respect to the housing edge surface.

A method of making a brake assembly. The method may include providing a brake pad carrier, an air operated brake actuator suitable for attaching to the brake pad carrier, and a hydraulically operated brake actuator suitable for attaching to the brake pad carrier, and attaching one of the air operated brake actuator and hydraulically operated brake actuator to the brake pad carrier to provide a brake assembly.

A disc brake caliper has a caliper body and a pair of pads and, in each side portion of the caliper body, a distal piston and a proximal piston, having radially distanced and aligned pressure centers.

A land vehicle includes a frame structure, a plurality of wheels supported by the frame structure, and a body supported by the frame structure. 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 body includes a first sidewall arranged on one side of the vehicle and a second sidewall arranged on another side of the vehicle opposite the first sidewall.

Land vehicles and methods of operating land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and a brake system. The frame structure includes a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction. The plurality of wheels are supported by the frame structure. Each of plurality of wheels is sized to permit direct integration of an electric motor therein.

A disc brake caliper includes an outer body, an inner body, and joining parts connecting the inner body and the outer body with each other at both end portions in a circumferential direction of a rotor so as to form an opening part. An inward end edge of both end edges in the circumferential direction of at least one of the joining parts, which defines an end part of the opening part in the circumferential direction, is inclined relative to an axial direction of the rotor towards a central part in the circumferential direction of the outer body from the inner body side to the outer body side, so that a length of the opening part in the circumferential direction is shortened from the inner body side to the outer body side.

A brake caliper assembly that includes a caliper body and a support member. The caliper body includes an inboard wall; an outboard wall; and a transverse wall connecting the inboard wall and the outboard wall. The support member is adapted to connect the brake caliper assembly to a vehicle. The support member is connected to the inboard wall at more than two support connections.
