摘要： A brake caliper comprises a motor having a shaft, at least one first planetary gear, and at least one second planetary gear. The at least one first planetary gear is rotatably engaged with the shaft and with a piston, and is operatively engaged with a first carrier. The at least one second planetary gear is operatively engaged with the first stage carrier and with a second carrier. A ball screw is engaged with the second stage carrier for rotation therewith, and a ball screw nut is operatively engaged with the ball screw. A parking brake for the caliper is also provided.

摘要： A master cylinder assembly including a boost assembly. The hydraulic master cylinder includes a cylinder defining an elongated bore, a piston slidably positioned in said bore, inlet means in the cylinder for admitting hydraulic fluid into the bore from a reservoir, and an outlet fitting in said cylinder communicating with said bore and operative to convey hydraulic fluid out of the bore for delivery to a brake device in response to linear movement of the piston in the bore. The boost assembly includes an electric motor. A hollow ball nut and screw assembly is operably connected to the motor. A screw of the ball nut and screw assembly is positioned to advance the piston in response to actuation of the motor. An input rod extending through the screw includes a first end positioned to receive a brake input force and a second end positioned to advance the piston independently from the screw. The assembly further includes sensing and control means to sense the brake input force and control the motor responsive to the brake input force.

摘要： A brake apparatus for a vehicle includes a housing including a bore formed therein. A piston is slidably positioned in the bore, the piston and bore defining a fluid chamber therebetween. A screw member is operatively engaged with the piston. The piston and screw member are movable based on fluid pressure in the fluid chamber and movable in a linear direction based on the rotational movement of the screw member.

摘要： A manually operated cable release apparatus, suitable for use in an electrically actuated brake, is provided for a locking mechanism having a shaft that is rotatable about an axis of rotation of the shaft, between a first angular position where the locking mechanism is disengaged, and a second angular position where the locking mechanism is engaged. The cable release apparatus includes a lever having one end thereof fixedly attached to the shaft and extending outward from the shaft for applying a force to the lever, for rotating the shaft back and forth through an angular displacement between the first and second angular positions. A cable is operatively connected to the lever in a manner allowing the shaft to rotate freely back and forth through the angular displacement of the shaft between the first and second angular positions without movement of the cable from a non-engaged position of the cable, and for engaging and applying a tensile force from the cable to the lever for rotating the shaft to the first position from any point in the angular displacement between the first and second angular positions of the shaft.

摘要： A ball screw apparatus includes a cylindrical screw shaft having a spiral groove in an outside peripheral surface, a cylindrical ball nut surrounding the screw shaft and having a spiral groove in an inside peripheral surface, and a plurality of bearing balls rotatably interposed the two spiral grooves, which are aligned and spaced apart such that the bearing balls are free to rotate as the ball nut rotates about and moves along the screw shaft. One or more of the screw shaft and the ball nut may include a spiral wire coil and a coil shape retention device. The opposed peripheral surfaces of adjacent coils of each spiral wire coil form the walls of one of the spiral grooves. Each coil shape retention device prevents the associated spiral wire coil from changing shape when the ball nut moves spirally relative to the screw shaft.

摘要： The problem of reliably locking an electrically actuated park brake is resolved through the use of a jaw-tooth clutch operatively installed between the shaft and the housing of a drive motor, for engaging the brake. The brake may be locked and unlocked by selectively engaging the jaw-tooth clutch either electrically or manually.
