  • Patent number: 10407041
    Abstract: An electric parking brake actuator has a transmission mechanism, which is rotationally drivable by an electric motor and converts rotational movement into an axial movement of an actuating rod that carries an actuating element for the parking brake. The actuating rod normally moves by electric motor displacement via the transmission mechanism from an unblocking position to a blocking position and vice versa. A blocking mechanism serves the purpose of holding the actuating rod in the unblocking position of the actuating rod against the force of a spring element. A blocking disc, which is in drive connection with the transmission mechanism, has a stop surface for a locking device in only one rotational direction of the blocking disc. For secondary alternate operation the stop surface is releasable by the locking device so that the actuating rod is biased by the spring element to the blocking position without electric-motorized assistance.

  • Patent number: 10000220
    Abstract: A brake caliper for a disk brake or to a disk brake with a brake caliper for rail vehicles. A brake caliper has caliper arms at which at the ends brake shoes are mounted and which are pivotally driven against each other by a brake cylinder. The brake caliper or disk brake has the advantage that the brake cylinder and the wear adjusting device are contained in a common housing and that the wear adjusting device acts along the same linear axis of movement as the force which is generated between two carriers which are pivotally connected to the caliper arms and drive the same for pivoting in order to subject the brake shoes to tension against each other.

  • Patent number: 9630508
    Abstract: A vehicle and a method for controlling regenerative braking may utilize the maximum available regenerative braking torque for some time during a braking event. As the vehicle speed and/or powertrain torque decreases, the regenerative braking torque is controlled to deviate from the maximum. The point at which the regenerative braking torque deviates from the maximum is chosen based on the level of vehicle deceleration. The regenerative braking torque is then smoothly blended out until it reaches zero. The regenerative braking torque is brought to zero when the vehicle speed is very low, thereby eliminating the inefficiencies associated with operating a motor at a very low speed.
