A braking assembly for inhibiting rotation of a wheel around a rotation axis is provided. The braking assembly includes a drive gear, an actuator, an electric braking assembly, a mechanical braking assembly including a brake pad, and a brake rotor fixedly coupled to the wheel. The drive gear rotates with the wheel and includes a pinion. The electric braking assembly includes a coil surrounding the rotation axis, and a magnetic disc assembly concentric with the coil and configured to rotate relative to the coil. The magnetic disc assembly includes a plurality of magnets at a perimeter of the disc. The actuator engages the pinion to inhibit rotation of the magnets and generate an electro motive force to inhibit rotation of the wheel. The actuator engages the brake pad to contact the rotor and inhibit rotation between the wheel and the brake pad.

A motor transmission unit for an electronic parking brake device includes a case, a driving member, a board, a rod and a push unit. The case is slidably mounted to a cap of a clamp. The driving member is partially inserted into the case. The board is threadedly mounted to the driving member. The rod is located between inner periphery of the passage and the board. The push unit has a first end thereof contacting the first end face, and a second end of the push unit is inserted in the clamp. A portion of the second end of the push unit contacts a piston. When the driving member is driven, the board moves axially. The board is restricted by the rod and does not rotate. The board pushes the push unit axially which moves the piston to push a lining plate of the clamp to contact a brake disk.

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.

Disclosed herein are a brake actuator and an electromechanical brake using the brake actuator and a control method thereof. The brake actuator provided in a disc brake to press or release a piston and controlled by an electrical signal includes a first actuator including a first power transmission unit configured to transmit power to the piston side; and a second actuator including a second power transmission unit configured to transmit power to the piston side; wherein the first and second power transmission units are arranged coaxially.

A brake system that includes a brake caliper comprising an inboard side and an outboard side, the inboard side of the brake caliper includes one or more brake pistons and the outboard side of the brake caliper comprises one or more brake pistons, and a brake pad comprising a first pad section and a second pad section. During a service brake apply, both of the first pad section and the second pad section are moved against a braking surface to create a clamping force. During a parking brake apply, only one of the first pad section and the second pad section is moved against the braking surface to create a clamping force. The first pad section comprises a friction material having a coefficient of friction that is different than a coefficient of friction of the second pad section.

A motor transmission unit for an electronic parking brake device includes a case, a driving member, a board, a rod and a push unit. The case is slidably mounted to a cap of a clamp. The driving member is partially inserted into the case. The board is threadedly mounted to the driving member. The rod is located between inner periphery of the passage and the board. The push unit has a first end thereof contacting the first end face, and a second end of the push unit is inserted in the clamp. A portion of the second end of the push unit contacts a piston. When the driving member is driven, the board moves axially. The board is restricted by the rod and does not rotate. The board pushes the push unit axially which moves the piston to push a lining plate of the clamp to contact a brake disk.

A brake system for a vehicle such as a bicycle is disclosed. The brake system may comprise an improved master cylinder assembly configured (e.g. manufactured/produced, assembled, etc.) so that a setting and/or adjustment of the brake stroke and/or lever action/actuation can be provided by any one independent mechanism (e.g. without any other adjustment mechanism) or by a combination of adjustment mechanisms (e.g. in a combination with one or more adjustment mechanism); operation of a mechanism for setting and/or adjusting the brake stroke may comprise a feature configured to engage a pushrod (e.g. by direct action on the pushrod or a feature of the pushrod or by indirect action through a link, adjuster, etc. configured to engage the pushrod). The master cylinder assembly may be configured to be set and/or adjusted/tuned within the indicated range to provide an intended performance and/or “feel” for the operator at the brake lever.

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.

The disclosure relates to the technical field of vehicle accessories, and in particular to a brake for a vehicle and a vehicle. The disclosure aims at solving the problems present in existing brakes for a vehicle that oil passages are relatively long, an angle at which each oil passage is arranged is relatively large, debris generated in a machining process remains in the oil passages and then causes blockage of the oil passages, and drilling holes in an inner caliper body and an outer caliper body to form the oil passages further reduces mechanical strength of the inner caliper body and the outer caliper body. For this purpose, the brake for a vehicle according to the disclosure comprises a first caliper body and a second caliper body, wherein the first caliper body is fixedly connected to the second caliper body, the first caliper body and the second caliper body are each provided with a piston chamber, a piston is arranged in each piston chamber, the first caliper body is provided with a first oil passage penetrating through the piston chamber in the first caliper body, the second caliper body is provided with a second oil passage penetrating through the piston chamber in the second caliper body, and the first oil passage fluidly connects with the second oil passage by means of a hard oil pipe. The foregoing arrangement can simplify oil passage pathways in the first caliper body and the second caliper body.
