  • Patent number: 8689942
    Abstract: The technology is directed to an energy storage and release system that stores energy and enables a repeatable and accurately timed release of energy. A shaft member supports a drive assembly, a locking assembly and a lever member there between. The lever member and locking assembly are attached to the shaft. The drive assembly rotates freely about the shaft and loads energy into a torsion spring in communication with the lever member. The torsion spring connects at one end to the drive assembly and at the other end to the lever member without contacting the shaft member. The locking assembly provides a triggered release mechanism for selective release of stored energy from the torsion spring that accordingly rotates the lever member. The system can automatically reload the torsion spring once a signal is received from any number of events including, when the rotating lever member contacts a stop member or limit sensor that signals the end of travel for the lever member in either rotational directions.

  • Publication number: 20130168482
    Abstract: An innovative and advantageous ratcheting system having a housing, a corresponding ratcheting member, and a primary ratcheting member. Wherein the members provide dependent interlocking behavior between the corresponding ratcheting member and the primary ratcheting member whereby the dependent interlocking behavior takes place on the adjoining surfaces orthogonal to the axis in which the ratcheting mechanism is rotatably mounted. Such interlocking behavior is dependent upon the direction of relative torque between the corresponding ratcheting member and the primary ratcheting member thereby allowing relative rotary motion in the first predetermined direction while preventing relative rotary motion in the second predetermined rotary direction. Further, the interlocking behavior between the corresponding ratcheting member and primary ratcheting member can be disabled whereby relative rotary motion between the ratcheting members can be achieved in the second predetermined rotary direction.

  • Patent number: 7472624
    Abstract: A brake actuating assembly for a vehicle having a brake system is provided. The assembly includes a mounting bracket for mounting the brake actuating assembly to the vehicle, and a pedal arm mounted to the mounting bracket for pivotal movement about a pivot axis. The pedal arm is connectable to the brake system such that movement of the pedal arm in a brake applying direction activates the brake system and movement of the pedal arm in a brake releasing direction de-activates the brake system. An arcuate rack of teeth is connected to the pedal arm, and a pawl that includes a tooth engages the rack. The assembly also includes a spring that has a first end that operatively connected to the pawl, and the second end that is operatively connected to the mounting bracket in an opening that includes a surface extending between a first stop and a second stop.

  • Publication number: 20080127772
    Abstract: A parking lock for a motor vehicle with an automatic or manual automatic transmission includes a parking lock wheel connected with the transmission output, a locking pawl pivotably attached by a parking lock bolt to a transmission housing. The locking pawl engages and disengages the parking lock wheel and has an end communicating with a guiding plate. A locking element is placed between the pawl and plate to prevent the pawl from disengaging the parking lock wheel. A hydraulic damping element, is at least operatively connected with the pawl, such that while disengaging the parking lock, movement of the pivotable end of the locking pawl toward the guiding plate is damped upon release of the parking lock thus preventing any undesired release jolt.

  • Patent number: 6962093
    Abstract: A noise reduction structure is provided for use with a meshing gear assembly, such as in a power take-off unit for selectively providing power to one or more rotatably driven accessories. The meshing gear assembly includes meshing input and output gears that are supported within a housing and are rotatably driven during use. A helical coil wrap spring extends about and is frictionally engaged with a portion of the output gear. A first end of the wrap spring extends outwardly therefrom to form a control tang that extends adjacent to an abutment surface provided on the housing of the power take-off unit. As a result, the wrap spring is prevented from rotating relative to the housing as the output gear is rotatably driven.
