A bicycle derailleur for operating a chain guide. The derailleur has primary actuator that imparts a primary displacement on the chain guide that has at least a component in an axial direction with respect to an assembly of toothed wheels. The derailleur also has secondary actuator that imparts a secondary displacement on the chain guide that has at least a component in a radial direction with respect to the assembly of toothed wheels. The secondary actuator can operate independently of the primary actuator.

An actuator (1) for a component, in particular for a transmission component of a motor vehicle, including a processor (2) which is connected to an electric motor (3) for the closed-loop or open-loop control thereof, a final control element (4) which can be moved by the electric motor (3), wherein at least one (actuator-integrated) vibration sensor (5) is coupled to the processor (2), and the processor (2) is designed to evaluate the signals delivered by the vibration sensor. A method for evaluating vibrations on a transmission component of a motor vehicle is also provided, in which vibrations on the transmission component are detected by a vibration sensor (5) on the actuator and are processed in a processor (2) of an electromotive actuator (1).

A device for the internal actuation of a gearbox includes a main axle mounted such that it can slide through a housing, and has a transverse extension capable of acting on an intermediate arm which is designed to conduct a gearshift fork. The intermediate longitudinal member is mounted translationally with respect to the housing.

An actuator module for a driveline assembly includes, among other things, a cover housing and a fork driving unit supported by the cover housing. The fork driving unit includes a fork driver and a pusher assembly coupled to the fork driver by spaced apart pusher ends. The fork driving unit also includes a drive assembly carried by the pusher assembly to translate the fork driver relative to the cover housing. The fork driving unit further includes a spring that biases the pusher assembly and fork driver to a neutral position.

An engagement device (1) for a transmission (G), the engagement device (1) including a gear shift sleeve (S) arranged between a first idler gear (LR1) associated with a shaft (W) of the transmission (G) and a second idler gear (LR2) arranged coaxially to the shaft (W). By displacing the gear shift sleeve (S) towards the first idler gear (LR1), a rotationally fixed connection between the shaft (W) and the first idler gear (LR1) can be established. By displacing the gear shift sleeve (S) towards the second idler gear (LR2), a rotationally fixed connection between the first idler gear (LR1) and the second idler gear (LR2) can be established. The first idler gear (LR1) includes a plurality of axially projecting extensions (F) which extend through openings (A) formed in the gear shift sleeve (S).

The present disclosure provides a transmission apparatus for an electric vehicle. The transmission apparatus for the electric vehicle includes a synchronization device connected to an input shaft, and a first shift device selectively engaged with the synchronization device to perform a gear shift operation, wherein the first shift device includes a first shift motor configured to receive power from the outside of the transmission apparatus and rotate, a first rotation shaft connected to the first shift motor to rotate about a rotation axis according to forward and reverse rotations of the first shift motor, a first movement block moving forward and backward in conjunction with the first rotation shaft, and a first shift fork connected to the first movement block to move integrally, and the synchronization device selectively operates to shift a gear as the first shift fork moves.

An actuation assembly for use in a drive unit assembly of a vehicle. The actuation assembly includes an actuator shaft that is connected to a shift shaft and a shift fork via a lever member. At least a portion of the lever member is connected to the shift shaft and at least a portion of the lever member is pivotably connected to said actuator shaft. An actuation mechanism drives the actuator shaft linearly to pivot the lever member which in turn rotates the shift shaft and the shift fork.

A shift drum has a recess which controls a fork to move one of two cooperating coaxially arranged gears for transmitting torque in a power train of a vehicle. The recess includes a straight section, which upon rotation of the shift drum does not move the fork either to the left or the right, and at least one ramp which does move the fork in one direction (i.e., to the left or the right). The ramp is more complex than a single line, such as having a first portion at a first right-shift portion ramp angle β and a second portion at a second right-shift portion ramp angle γ, perhaps with the intersection between the first right-shift portion ramp angle β and the second right-shift portion ramp angle γ being at the mid-line defined by the straight section of the recess.

In at least some implementations, a rotary actuator includes a drive assembly including a motor and one or more gears coupled to and rotated by the motor, an output rotated by the drive assembly and a housing. The housing includes a first portion and a second portion coupled to the first portion to define an interior in which at least part of the drive assembly is received. The housing also includes a first motor locating feature that engages the motor and positions the motor within the housing and prevents rotation of the motor, and a first gear locating feature that locates and retains the position of at least one of said one or more gears. The first motor locating feature and first gear locating feature are both integrally formed in the housing.

The invention relates to a linear actuator (1) for an automobile transmission comprising an electric motor (6) for moving a transmission control member (5) between a plurality of shift positions, a spring (15) for driving the transmission control member (5) to an end position of the shift range in case of electric power failure, and a worm screw (7) to drive a displaceable worm wheel (10) with a pinion (11) meshing with a displaceable gear rack (12). The transmission control member (5) is displaceably coupled to the worm wheel (10). The gear rack (2) is blocked by an electrically activated lock against linear displacement with the spring (15) in a compressed state such that upon interruption of power supply to the lock the gear rack (12) is released and linearly displaced by the spring (15) thereby shifting the transmission control element (5) to its end position.
