A brake device, configured to be installed directly on a driving axle or through a hub, wherein said device includes a first brake disc joined to the axle sharing rotary motion, a first container disc and a second container disc configured to be moved in the axial direction of said axle. The container discs are positioned on each side of the brake disc, such that both are configured to be moved in the axial direction towards the linings of the first brake disc and to exert a pushing pressure thereon, producing the braking of the brake disc and, therefore, of the driving axle whereon it is assembled. Furthermore, the container discs comprise an inner circuit configured to accommodate the passage of a coolant configured to cool them.

A transmission assembly for a brake booster of a vehicle is disclosed. The transmission assembly comprises a rack module having a base section and at least one tooth row section; and at least one transmission arrangement for transmitting a moment, such as a torque. The at least one transmission arrangement is in engagement with the at least one tooth row section of the rack module and has a shaft, a screw wheel carried by the shaft and a cylindrical wheel. The at least one transmission arrangement has at least one relief element, which is arranged effectively in a load path of the at least one transmission arrangement, and brake booster for a vehicle that comprises an electric motor, a push rod and a transmission assembly, which acts between the electric motor and the push rod.

A brake assembly including a first brake piston; a second brake piston; and a parking brake assembly. The parking brake assembly includes a power transfer mechanism and a motor providing power to the power transfer mechanism. During a parking brake apply, the power transfer mechanism provides the power to both the first brake piston and the second brake piston so that both the first brake piston and the second brake piston are moved until a resistance of the second brake piston becomes higher than a resistance of the first brake piston. The power transfer mechanism then transfers the power from the second brake piston to the first brake piston so that the second brake piston ceases to move and additional power is supplied to the first brake piston.

Provided is a brake apparatus for a vehicle including a pair of brake pads that are disposed to face each other on a caliper body and disposed on two sides of a wheel disc, respectively, a first worm shaft part that is connected to a motor part, a first worm wheel part that is engaged with the first worm shaft part and rotates with rotation of the first worm shaft part, a second worm shaft part that is connected to the first worm wheel part and rotates together with the first worm wheel part, a second worm wheel part that is engaged with the second worm shaft part and includes a plurality of second gear teeth, and a linear motion conversion unit that is coupled to the second worm wheel part and converts a rotational motion of the second worm wheel part into a linear motion.

Disclosed is an electronic parking brake system, which is configured to push first and second brake shoes respectively disposed on inner opposite sides of a drum to an inner surface of the drum for braking, including an actuator including a motor configured to rotate forward and reverse to generate a driving force for braking, and a reduction gear unit configured to amplify the driving force transmitted from the motor, and a power converter configured to convert a rotational motion from the actuator into a linear motion to press or release the first and second brake shoes.

The present invention relates to an electronic parking brake and, more specifically, to an electronic parking brake in which an electronic actuator is applied to a drum brake, wherein noise can be reduced when transmitting the driving power of a driving motor, and a rotary shaft of the driving motor and a rotary shaft of a wheel cylinder can be arranged so as to be inclined relative to each other.

A brake adjuster with a housing configured to be coupled to a brake actuator push rod, and a control unit rotatably coupled to the housing. The control unit is configured to be coupled to a reference point of a vehicle and to cause adjustment of the brake as the brake actuator push rod retracts. One of the housing and the control unit has a first indicator and a second indicator, and the other of the housing and the control unit has a third indicator. The third indicator is adjacent the first indicator when the brake actuator push rod is retracted in a brake disengaged position, and the third indicator is adjacent the second indicator when the brake actuator push rod is extended to a brake over-stroke position. The indicators may be any combination of notches, protrusions, marks, or pointers.

A generator for comprising a rotor, an inner shaft, an outer shaft, and an actuation means. The inner shaft is at least partially disposed inside the outer shaft. The inner shaft is coupled to the outer shaft by means of a translatable drive connection. The actuation means is configured to actuate the second shaft towards a retracted position. The translatable drive connection is configured to allow a transfer of torque between the first and second shafts, and enables movement of the second shaft, relative to the first shaft, along its axis of rotation from an extended position to a retracted position, such that an input portion of the second shaft can be at least partially retracted in a retraction direction towards the rotor upon activation of the actuation mechanism. A disconnect mechanism disposed on the second shaft can therefore be disconnected upon retraction of the second shaft.
