Abstract
A gear shift mechanism has a displacement device, which can be operated by an actuator, for the axial displacing of a sliding sleeve. The actuator is connected with the displacement device by way of at least one joint. Such an articulated connection between the actuator and the displacement device permits a greater freedom with respect to the spatial arrangement of the actuator and thus a very compact construction.
Claims4
A gear shift mechanism comprising:
- a plurality of actuators, wherein associated with each actuator are;
- a fixed sleeve which is non-rotatably connected with a shaft;
- a sliding sleeve which is non-rotatably and axially displaceably along a longitudinal axis of the sliding sleeve arranged on the fixed sleeve;
- and
- a displacement device for axial displacement of the slide sleeve;
- wherein each actuator operates its displacement device to axially displace its sliding sleeve,
- wherein each actuator is connected by way of at least one joint with its displacement device,
- wherein three shifting channels are provided and wherein one fixed sleeve, one sliding sleeve, one displacement device and one actuator are assigned to each of the three shifting channels, and
- wherein two exterior actuators of the three actuators are arranged diagonally with respect to a longitudinal axis of the assigned sliding sleeve and wherein a center actuator of the three actuators is arranged coaxially with respect to a longitudinal axis of its assigned sliding sleeve and is rigidly connected with its assigned displacement device.
