Abstract:
An actuating device for an operating element such as a clutch (4) in the power train between the engine (2) and the driven wheels (12) of a motor vehicle consists of a parallel arrangement of at least two actuators (25a, 25b) that are controlled by an electronic control device (31) so that they can work simultaneously or one after the other, or with a partial time overlap where one starts to work after an initial current surge to the other has subsided.
Abstract:
The power train of a motor vehicle employs an automated transmission and an automated clutch between the transmission and the combustion engine. The clutch is automatically disengaged prior to, and is automatically reengaged after, each selection of a particular gear of the transmission. A common first actuator (such as a reversible stepping motor) is employed to select the condition of the clutch and to select various gears, and a second actuator is used to effect actual shifting of the transmission into or from a selected gear. The connection between the first actuator and a clutch operating member comprises a reciprocable or rotary first cam, and the connection between the first actuator and a gear selecting member comprises a preferably rotary second cam which receives motion from the first cam.
Abstract:
A control unit for a friction clutch or another torque transmitting system and/or for a transmission system in a motor vehicle employs an actor having an electric motor arranged to drive a single-stage or multi-stage transmission which, in turn, transmits motion to one or more mobile parts of the torque transmitting and/or transmission system by way of one or more output elements of the actor. The motor receives signals from one or more sensors and/or from the electronic circuitry in the vehicle and/or from a memory. At least one coil spring and/or another energy storing element is or can be provided to guarantee that the torque transmitting system assumes a predetermined (e.g., disengaged) condition and/or that the transmission system is in a predetermined gear ratio when the actor is not in use to change the magnitude of torque being (or to be) transmitted by the torque transmitting system and/or the ratio of the transmission system.
Abstract:
The invention relates to a gear actuator for a motor vehicle transmission design, that has several ratio steps for forming gears, whereby the gear actuator has a gear-shift shaft that is mounted so that it can rotate for the shifting of gears and that is mounted so that it can slide axially for the selection of gears and whereby the gear actuator also has a shift gate, whereby the shift gate also has a fixed mounted first shift gate part that is especially a shaft or an axle, as well as a second shift gate part that is mounted so that it can move axially and move in rotation or swivel, which is especially a disk or plate and is coupled with the gear-shift shaft and whereby the first shift gate part has several axially spaced recesses, into which the second shift gate part can be swiveled depending on its axial position.
