The present teachings provide for an actuator system including a support; a drive system connected to the support; a shift fork operatively connected to the drive system and configured to move a distance defining a stroke length between a disengaged position and an engaged position, the shift fork having a cam follower; a cam assembly operatively connected with the drive system to move between a neutral position, and a shifted position, with a plurality of intermediate positions between the neutral and shifted positions, the shift fork being in the disengaged position when the cam assembly is in the neutral position, the cam assembly including: a cam having an aperture defining an interior surface; a hub housing disposed within the aperture of the cam and connected to the drive system; and a biasing member disposed within the aperture and preloaded between an interior surface of the aperture and the hub housing.

Actuator system

The present teachings provide for a system comprising a gearbox including a gear assembly, the gearbox having an outer surface, the outer surface with a pair of apertures; and an actuator. The actuator including a support with a pair of lugs, with each lug having an opening; an drive system connected to the support; a shift fork including a pair of arms, the shift fork in communication with the drive system and configured to move a distance defining a stroke length between a disengaged position and an engaged position; and an actuation assembly operatively connected with the drive system to move the shift fork between a neutral position, and a shifted position, with a plurality of intermediate positions between the neutral and shifted positions. The actuator is mounted onto the outer surface of the gearbox, with the pair of lugs extending into the pair of apertures of the gearbox, and at least a portion of the shift fork extends extending through the lugs into and below the outer surface of the gearbox. The portion of the shift fork within the gearbox engages a gear assembly within the gearbox.

External actuator system

The invention relates to a linear actuator () for an automobile transmission comprising an electric motor () for moving a transmission control member () between a plurality of shift positions, a spring () for driving the transmission control member () to an end position of the shift range in case of electric power failure, and a worm screw () to drive a displaceable worm wheel () with a pinion () meshing with a displaceable gear rack (). The transmission control member () is displaceably coupled to the worm wheel (). The gear rack () is blocked by an electrically activated lock against linear displacement with the spring () in a compressed state such that upon interruption of power supply to the lock the gear rack () is released and linearly displaced by the spring () thereby shifting the transmission control element () to its end position.

Linear actuator with safety mechanism

A shifter assembly including a shift lever pivotally mounted to a housing, a shift lever, a first pivot mechanism, a gimbal ring, and a second pivot mechanism. The lever is movable in a first gate along a first plurality of paths, a second gate along a second plurality of paths, and a bridge gate between the first and second gates. The first pivot mechanism is mounted to the lever to permit movement about a first pivot axis within one of the gates. The gimbal has an aperture and is disposed about and coupled to the lever. The second pivot mechanism is mounted to the gimbal to permit movement about a second pivot axis within another one of the gates. The axes are spaced from each other. The gimbal has receivers recessed from the inner surface with the first pivot mechanism engaging the receivers to couple the lever to the gimbal.

Shifter assembly having a pivot mechanism

A compact and efficient rotary shift actuator for a shift-by-wire transmission includes a motor having a motor shaft that is rotatable about a motor axis, an output head arranged towards a second end of an output lever and adapted for connection with a shift shaft of a transmission, and a gear train for transferring torque from the motor shaft to the output head. The gear train comprises a first shaft rotatable about a first axis, a second shaft rotatable about a second axis, and the output lever pivotable about a lever axis. The gear train further includes a worm gear for transmitting torque from the first shaft to the second shaft.

Rotary shift actuator for a shift-by-wire transmission

A linear actuator assembly () having an inner sleeve () which moves in a first direction or in an opposite second direction relative to a fixed outer sleeve () between a fully extended position and a fully retracted position. The linear actuator assembly () includes a stop mechanism () limiting the movement of the inner sleeve () relative to the outer sleeve () in the extended position, the stop mechanism () having a first portion () associated with said outer sleeve () and a second portion () associated with said inner sleeve () with the first () and second () portions abutting each other when said inner sleeve () is in the extended position to define a hard stop.

Linear actuator assembly

A linear actuator assembly () having an inner sleeve () which moves in a first direction or in an opposite second direction relative to a fixed outer sleeve () between a fully extended position and a fully retracted position. The linear actuator assembly () also has an emitter () and a sensor () positioned near the emitter () that detect changes in an emitted signal resulting from the movement of the inner sleeve () relative to the outer sleeve () along a longitudinal axis and a controller () electrically coupled to the sensor () to determine the axial position of the inner sleeve () relative to the outer sleeve () along the longitudinal axis.
