  • Patent number: 10903715
    Abstract: An assembly that includes a main housing. A motor is supported in a motor housing that is supported in the main housing. The motor has an output shaft and a locking mechanism. The motor is adapted to generate a first rotational direction torque and a second rotational direction torque. The motor is adapted to transfer the first rotational direction torque and the second rotational direction torque to a destination via the output shaft. The locking mechanism is adapted to prevent the output shaft from back driving in the second rotational direction after the first rotational direction torque has been transferred to the destination. The motor housing is adapted to rotate in the main housing to unlock the locking mechanism so that the second rotational direction torque can be transferred to the destination.

  • Patent number: 10759401
    Abstract: A brake controller for controlling the brakes of a towed vehicle which is pulled by a towing vehicle comprises a sensor assembly which determines the position of the brake pedal of the towing vehicle, and if necessary, compensates for inertia which can affect the output of some sensors. The output of the sensor assembly is transmitted to a processor, which in turn transmits a signal (the strength of which is a function of the pedal position) to brakes of the towed vehicle to activate the brakes of the towed vehicle.

  • Patent number: 10683188
    Abstract: During normal operation of a textile machine, a fiber bundle is supplied to a consolidating means to produce a roving having a protective twist, the roving wound onto a tube with a winding device. The roving downstream of the consolidating means is monitored for whether the roving is being produced by the consolidating means or whether the roving produced by the consolidating means is being wound onto the tube. In no roving is being produced or the roving produced by the consolidating means is not being wound onto the tube, an interruption of the normal operation of the textile machine is initiated and the tube partly loaded with roving by the winding device prior to the interruption is replaced with an empty tube during a tube changing process. The consolidating means is started up and the roving produced thereby is brought into contact with the empty tube. Normal operation is resumed and the roving is wound onto the empty tube.

  • Patent number: 10527411
    Abstract: An electro-magnetic brake which is switched between an operative braking position and an inoperative position by transient pulses of current. It is held passively in the operative and inoperative positions with little or no current. This prevents the generation of heat, which would affect the accuracy of measurements where the brake is used in dimensional measuring equipment. In one form, permanent and semi-permanent magnets are arranged in parallel, and the magnetic polarity of the arrangement is flipped by transient current pulses in a surrounding coil. A capacitor may provide a reservoir of current to activate the brake in the event of a power supply failure.

  • Patent number: 10457263
    Abstract: When detecting a maladjusted brake component on a commercial vehicle, wheel end temperature is determined as a function of resistance measured by a wheel speed sensor at a wheel end. The measured temperature is compared to low and high temperature thresholds defined by a thermal model, as well as to one or more other wheel speed sensor temperatures. If the measured temperature is below the low temperature threshold and substantially different than the one or more other wheel speed sensors, the brake is determined to be under-adjusted and brake force at the under-adjusted brake is increased. If the measured temperature is above the high temperature threshold and substantially different than the one or more other wheel speed sensors, then the brake is determined to be over-adjusted, and brake force is reduced or modulated at the over-adjusted brake to prevent overheating.

  • Patent number: 9387845
    Abstract: Upon a start of a release for releasing a braking state of a parking bake in a process of step 2, a control unit (13) performs hydraulic maintaining control by an ESC (11) in a subsequent step, step 3. As a result, a hydraulic pressure in a cylinder portion (46) increases according to a retraction of a piston (49) of a disk brake (41). If the control unit (13) determines in step 4 that the release of the parking brake has been completed, in step 5, the control unit (13) releases the hydraulic maintaining control by the ESC (11). The hydraulic pressure is temporarily increased in the cylinder portion (46) of the disk brake (41), thereby increasing an elastic deformation amount of a piston seal (56) to succeed in acquiring a sufficient rollback function.

The brake plunger is led through an opening of a closure cover that closes a receiving chamber of the brake caliper. A bellows rests against the brake plunger and, on the other side, against the closure cover to seal the receiving chamber. A secondary seal is retained on the closure cover, which secondary seal is arranged concentrically to the bellows and rests against the brake plunger. The secondary seal is configured to rest slidingly against the brake plunger.
