Abstract:
The invention relates to a load torque lock (100) having a brake element (40) in particular designed as a torsional spring and frictionally interacting with a brake body (36) for locking a torque, and having a drive wheel preferably rotatably supported on an axle (17) and coupled to at least one pusher (20) interacting with the drive wheel (18) for transmitting a torque from a drive motor (12), wherein the pusher (20) comprises at least one contact region (32) to the brake element (40) by means of which a torque to be locked can be introduced into the braking body (36) by means of the brake element (40). According to the invention, the pusher (20) is made of a first pusher element (24) and a second pusher element (30) designed as a separate component, such that the first or second pusher element (24, 30) comprises at least one pusher dog (26) engaging in a penetration (27) in the drive wheel (18), such that both pusher elements (24, 30) are disposed on different sides of the drive wheel (18), with the exception of the at least one pusher dog (26).
Abstract:
A decoupler assembly with a torsional damping system and a torque limiter. The torsional damping system has a torsion spring that facilitates transfer of rotary power into a hub. The torque limiter is wrapped about the torsion spring and radially expands with the torsion spring as a magnitude of the rotary power transmitted through the torsion spring increases. Contact between the torque limiter and another structure in the decoupler assembly halts radial expansion of the torsion spring.
Abstract:
In a force transmission system with a wrapping spring-type wraparound element and with a frictional surface assigned to the wraparound element, a switching device is provided for switching the wraparound element between two switching states is provided. In the first switching state, the wraparound element is operatively connected in a force-transmitting manner to the frictional surface. In the second switching state, it is operatively connected thereto in a non-force-transmitting manner. In the second switching state, the wraparound element is fully lifted off the frictional surface. The force transmission system is suitable in particular for a drive system of an adjusting element of a motor vehicle.
Abstract:
An anti-pinch system of a vehicle closure includes a detection system for detecting pinching and a clutch to disconnect the vehicle closure from a closure driving mechanism following detection of pinching by the detection system. The closure drive mechanism can be disengaged to prevent an increase in pinching during the time required to reverse the movement of the closure driving mechanism.
Abstract:
A decoupler assembly for transferring rotary movement between an engine driven shaft and a serpentine belt. The decoupler includes a hub configured to be assembled to the shaft. The hub has a helical first slot formed therein. A pulley is rotatably coupled to the hub. A carrier is mounted on the hub and includes a helical second slot formed therein, as well as an anti-ramp up boss formed thereon. A thrust plate is fixed to the hub and has a slot formed therein. A torsion spring is compressed between a hub end retained in the helical first slot and a carrier end retained in the helical second slot for transferring torque between the hub and carrier. The anti-ramp up boss travels within the slot formed in the thrust plate for limiting rotation between the carrier and thrust plate and preventing rotation of the torsion spring relative to the hub and carrier.
Abstract:
A dual rack and pinion system is provided for a window lift mechanism. The window lift mechanism includes improved window brackets for simple mounting to a window. A modular frame design is provided to improve assembly of the window lift mechanism into the door of a vehicle. An improved assembly method is provided for the dual rack and pinion system. The system is also provided with a smart motor and incorporates resilient shock absorbers in the dual rack and pinion gear train to allow more time for the smart motor to detect and react to an obstruction in the window. The window lift mechanism includes a support bracket mounted to the window and a motor supported on a support bracket, wherein the support bracket permits axial and rotational movement of the window relative to the support bracket.
Abstract:
A motor drive system includes a motor having a rotary motor output shaft, a driven component, and a flexible coupling connecting the motor output shaft to the driven component. The flexible coupling is a helix formed of a first wound wire. The helix has a helix unbonded free length that is less than about two times a helix outer diameter. The approach is particularly suitable for miniature motors and their driven components, wherein the motor output shaft has a shaft diameter of less than about 3 millimeters and the helix outer diameter is less than about 3 millimeters.
Abstract:
A braking system for a vehicle manual window-lifting mechanism prevents a window from dropping as a consequence of vibrations and minimizes angular play in a crank shaft. The system includes a helical spring that assists the crank shaft and that has a geometry modified from its conventional design. An included angle between the radial side pieces at which the winding ends terminate is an acute angle. One of the side pieces is coupled inside a radial hollow of the crank-driven shaft itself. The other side piece is located between the crank shaft and the drum, which rotate relative to each other. As a result, instead of the usual 40null or 45null of free play, the invention allows a maximum free play of only 10null to 15null in the crank shaft.
Abstract:
A window lift mechanism for raising and lowering a window in a vehicle door includes a support bracket mounted to the window and a motor supported on the support bracket, wherein the support bracket permits the axial and rotational movement of the window relative to the support bracket. A pair of parallel, vertical racks are mounted to the door and are positioned immediately adjacent to the window. A worm gear is driven by a worm with a lead angle greater than seven degrees coupled to a motor. A clutch mechanism is utilized to prevent back drive of the worm/worm gear system. The worm gear is operatively coupled to a pinion gear with resilient shock absorbers that are provided with notched surfaces to accommodate for compression of the resilient material with an enclosed space.
Abstract:
A clutch is arranged between a rotatable shaft and a worm shaft in a motor. The clutch includes a driving-side rotator connected to the rotatable shaft, a driven-side rotator connected to the worm shaft, a spring support and a coil spring arranged in the spring support. When the driving-side rotator is rotated upon energization of the motor, the coil spring is wound by the driving-side rotator to reduce an outer diameter of the coil spring, so that the rotation of the driving-side rotator is transmitted to the driven-side rotator and the worm shaft. When the driven-side rotator is rotated by an external mechanical force, the coil spring is unwound by the driven-side rotator to increase the outer diameter of the coil spring, so that a frictional force between the spring support and the coil spring is increased to restrain rotation of the driven-side rotator.
