Methods and systems for a vehicle transmission are provided herein. The vehicle transmission includes an input interface configured to mechanically couple to a motive power source. The vehicle transmission further includes a first disconnect device releasably mechanically coupling a first output to a first drive axle and a second disconnect device releasably mechanically coupling a second output to a second drive axle.

A braking device for an in-wheel motor may include: a stator; a rotor configured to rotate when power is applied to the stator; a disk interlocked with the rotor; a bracket coupled to the stator and a knuckle; and a caliper mounted on the bracket, and configured to press the disk.

The invention relates to a disk brake system for a vehicle, with single-sided pressure application, comprising a brake disk (1) comprising a hub portion (1.1) and a friction ring (1.2), a friction surface (1.3) of the friction ring (1.2) extending between an inner circumferential edge (1.4) and an outer circumferential edge (1.5) of the friction ring (1.2), a housing (2) with at least one piston (3, 3′, 3″) for actuating a first brake pad (4), the first brake pad (4) being configured to be pressed against the friction surface (1.3) of the friction ring (1.2) for braking, the disk brake system being devoid of an opposing brake pad opposite to the first brake pad (4). The invention also relates to a vehicle comprising at least one brake system of this type.

A hydraulic braking device includes an engaging base, a hydraulic brake, and a locking device. The hydraulic brake is provided on the engaging base. The locking device is adapted to fix the engaging base on a suspension fork of a bicycle, and includes a bolt and a handle, wherein the bolt passes through the engaging base to be screwed into a tapped hole of the suspension fork. The handle has a cam-shaped head pivotally connected to the bolt, and is pivotable between a first position and a second position. When the handle is located at the first position, the head presses against the engaging base to fix the engaging base on the suspension fork. When the handle is located at the second position, the engaging base is no longer being pressed against by the head, whereby the engaging base is movable relative to the suspension fork.

A piston housing may comprise: a main annular ring defining a main bore; a torque takeout annular ring defining a torque takeout bore; a torque takeout arm extending from the main annular ring to the torque takeout annular ring and defining an aperture therethrough; and a structural rib disposed within the aperture and extending from the main annular ring to the torque takeout annular ring.

A disc brake boot and a disc brake including the same are provided. The disc brake boot includes: a main body formed with a hollow that runs lengthwise through which a guide rod passes and is coupled; a first outer projection that is formed on an outer side of the main body in such a way as to protrude a set distance from one edge of the main body, along the perimeter of the main body; and a second outer projection that is formed on the outer side of the main body in such a way as to protrude a set distance along the perimeter of the main body, spaced apart from the first outer projection.

A braking system having an electromechanical braking function may include a compound caliper device including a motor and configured to press a pair of brake pads against a brake disk, a hydraulic pressure producer including a master hydraulic line receiving oil from a master cylinder, a master valve configured to open and close the master hydraulic line, a caliper hydraulic line connected to the compound caliper device, and a hydraulic pump configured to increase hydraulic pressure supplied to the compound caliper device, and a brake controller to control the motor and the hydraulic pressure producer, in which the brake controller is configured to close the master valve and decrease clamping force of the brake pads applied by the motor when a conversion condition for converting a parking brake stage into a primary brake stage is satisfied.

A power booster includes a conversion device, a power boosting component, a power boosting friction block, a friction part, a power boosting support, a sliding device. The conversion device is fixed to the power boosting component, the power boosting friction block is fixed to the power boosting component, the power boosting friction block and the friction part contact with each other after being pressed, the power boosting component is movably connected to the power boosting support, the friction part is movably connected to the power boosting support, the sliding device is connected to the power boosting component and the power boosting support. The power booster introduces the controlling force from the inlet, and amplifies the controlling force. The amplified controlling force is output by the power boosting component to push the part that needs to be controlled.

A deaeration valve (1) for a hydraulic coupling, such as a hydraulic coupling for distributing torque in a vehicle, said valve (1) comprising a valve member (3) and a valve housing (2), the valve housing (2) supporting the valve member (3) for reciprocal movement between two closed end positions.
