A vehicle includes: a transmission including an input shaft that receives power inputted from a power source for travel of the vehicle and an output shaft that outputs power to a drive wheel; a manual gear shifting power transmission mechanism that delivers an operation force of a driver as gear shifting power to the transmission; a clutch disposed between the power source for travel of the vehicle and the input shaft; and a controlled clutch actuation power transmission mechanism that delivers power of a clutch actuator as clutch actuation power to the clutch.

The invention relates to an electrohydraulic brake unit (10) for a motor vehicle, comprising a pressure source (36) designed as an actuator (30), at least one brake piston (70, 80), and a brake circuit (38), which connects the pressure source (36) and the at least one brake piston (70, 80) to one another, wherein the pressure source (36), the at least one brake piston (70, 80) and the brake circuit (38) are arranged in a wheel brake. The invention moreover relates to a vehicle having such an electrohydraulic brake unit (10) and a method for activating the electrohydraulic brake unit (10).

An actuator device of a braking device and a clutch may have a pump provided with a single operating device for pressurizing a fluid by a float, and a first delivery circuit and a second delivery circuit fluidly connected to an outlet of the pump. The first delivery circuit may be fluidly connectable to a braking device, the second delivery circuit may be fluidly connectable to a clutch. The actuator device may have a diverter device suitable for fluidly connecting the output of the pump alternately with the first delivery circuit and with the second delivery circuit, so as to alternately actuate the braking device or the clutch.

A system is disclosed for locking and unlocking a rotatable shaft connected to a drive motor. The system includes a fluid actuated lock piston operable to move between locked and unlocked positions to selectively lock the rotatable shaft to a fixed housing.

Example hydraulic brake actuators and related methods are disclosed herein. An example hydraulic brake actuator includes a rotary valve disposed in a bore of a housing. The rotary valve includes a shaft rotatably disposed within a sleeve. The sleeve and the shaft have ports that align at certain rotational positions to create a flow path between the bore and an inner chamber of the shaft. The example hydraulic brake actuator also includes a pump coupled to the shaft to increase and decrease a pressure within the inner chamber of the shaft.

A brake used by a mine hoist, a car, a high-speed train, etc. Gas springs are used to replace belleville springs, and a positive pressure is also always applied to brake pads to both ensure and increase the brake reliability and a positive pressure per unit area. The brake resolves problems such as deformation of the belleville springs, a serious change in an elastic force, sudden cracking and decompression, inconvenient monitoring, and a manufacturing difficulty. A brake head floating structure is used to reduce a requirement on end face runout of a brake disc. An oil-gas linkage plunger pump is used to replace a hydraulic station, which greatly reduces manufacturing costs, and reduces energy consumption.

A brake device is configured to apply a braking force to a rotary body of a human-powered vehicle. The brake device includes a power transfer medium operated braking portion, a first actuator and a second actuator. The first actuator is operatively coupled to the power transfer medium operated braking portion by a power transfer medium. The second actuator is operatively coupled to the first actuator and operated by electric power in accordance with an input to an operating device.

An electrical machine is presented. The electrical machine comprises a rotor, a stator, a housing and a first and a second fluid chamber in fluid communication via at least one fluid passage of the rotor. The rotor upon rotation is adapted to provide a difference in pressure between the first fluid chamber and the second fluid chamber by transfer of fluid there between, whereby a braking torque is exerted on the rotor.
