摘要:
A brake system, in particular a dual circuit brake system, for a motor vehicle, includes brakes which can be activated by a brake pedal operatively connected to a brake servo. Each brake engages one wheel. The brake system is designed such that a brake servo is assigned to each brake of at least one brake circuit, and the brake servos can be activated by the brake pedal.

A latching device including a reversibly rotatable drive gear, a reversibly rotatable driven gear meshing with the drive gear, and a cantilever including a latching gear meshing with one of either the drive gear or the driven gear. The cantilever includes an electrically distortable polymeric material configured to distort in response to an applied current to position the latching gear in an intermeshing relationship with both the drive gear and the driven gear, such that the drive gear, driven gear, and latching gear selectively prevent rotational motion of the gear assembly in a predetermined direction. Also, an electromechanical brake assembly including a rotary motor and the latching device, where the gear assembly selectively prevents rotational motion of the rotary motor in a brake-disengaging direction.

A brake structure for a roll-up door includes a brake drum fixed to a transmission shaft of a speed reducer. The brake drum receives a pair of brake shoes in opposite inner sides thereof. The brake shoes are pivotably connected to each other at an end of each brake shoe. A linking resilient member is connected between the free ends of the brake shoes. A brake pad is attached to a surface of each brake shoe facing the inner surface of the brake drum. A controlling lever is disposed at the top of the speed reducer corresponding to the free ends of the brake shoes. One end of the controlling lever is connected to an end of a fixing resilient member. The other end of the fixing resilient member is connected to a moving iron of a first solenoid. A clasping block is connected to the moving iron of the first solenoid. The other end of the controlling lever is connected to a moving iron of a second solenoid. A controlling block is disposed at the controlling lever between the free ends of the brake shoes and in contact to the free ends of the brake shoes. A brake control solenoid is disposed at the top of the speed reducer. The brake control solenoid is connected to a power supply with capacitance character. A moving iron of the brake control solenoid is connected to a connecting rod mechanism. The clasping block is connected to the connecting rod mechanism.

The invention provides an electric brake system and method. The electric brake system includes an electric motor having a portion moveable along a path between a plurality of positions for moving a brake pad and applying a selectable amount of braking force on a brake rotor. One of the plurality of positions is a minimal contact position. The minimal contact position is operable to change among the plurality of positions over time. The electric brake system also includes an electric controller for controlling the electric motor to move the portion along the path between the minimal contact position and at least one other of the plurality of positions for moving the brake pad and for selecting the amount of braking force. The electric brake system also includes at least one sensor for sensing at least one of motor current, motor acceleration, controller voltage, motor speed, motor voltage, and motor temperature, and communicating a sensed condition to the controller. The controller is operable to change the minimal contact position in response to the condition sensed and communicated by the at least one sensor.

The present device relates to an electromechanically operated parking brake for motor vehicles that is designed as a drum brake of the ‘Duo-Servo’ type, including a floatingly supported expanding lock which is operable by an electromechanical actuator arranged on a wheel support member and which acts on two brake shoes. To ensure the floating support of the expanding lock that is formed of a threaded-nut/spindle assembly and to always provide a desired application force, the invention discloses that the threaded nut on its outside circumference has a spur toothing which forms a spiral-toothed gear wheel system along with a spiral-toothed gear wheel driven by the electromechanical actuator.

A control system for a vehicular braking system incorporating a hydrodynamic brake and a friction brake. The control system optimizes the cooperation by the hydrodynamic brake and the friction brake and improves the reliability of operation thereof by producing a control signal corresponding to the desired total braking torque and applying this control signal as an input variable to an open-loop associated with the hydrodynamic brake and to a closed-loop associated with the friction brake with a signal responsive to the instantaneous deceleration being fed back to the input of the closed-loop.
