Abstract
A clutch for selectively coupling a motor and a motor vehicle drive train includes a housing having two pressure chambers, a shift sleeve, an actuating cap arranged for moving the shift sleeve, a piston, an idler gear and a mechanical engaging element. The piston is arranged in the housing between the two pressure chambers in a pressure-dependent, axially movable manner and is connected to the actuating cap. The mechanical engaging element is arranged between an axially movable component and an axially fixed component to engage the shift sleeve in two different axial positions. The axially movable component may be the shift sleeve or the piston, and the axially fixed component may be the housing or the idler gear.
Claims11
A clutch for coupling and decoupling a motor from a motor vehicle drive train, comprising a piston which is arranged in a housing between two pressure chambers in a pressure-dependent axially moveable manner, wherein the piston is connected to an actuating cap which is designed for contacting or moving a shift sleeve, wherein at least one mechanical engaging element is designed and arranged between an axially moveable component and an axially fixed component such that the shift sleeve can be engaged in two different axial positions, and wherein the at least one mechanical engaging element is arranged in a spring-loaded manner in a seat in the axially fixed component in order to selectively engage in a latching manner in two grooves in the axially moveable component.
A clutch for selectively coupling a motor and a motor vehicle drive train, comprising:
- a housing comprising two pressure chambers;
- a shift sleeve;
- an actuating cap arranged for moving the shift sleeve;
- a piston arranged in the housing between the two pressure chambers in a pressure-dependent, axially movable manner and connected to the actuating cap;
- and
- an idler gear;
- a mechanical engaging element arranged between an axially movable component and an axially fixed component to engage the shift sleeve in two different axial positions, wherein:
- the axially movable component is the shift sleeve or the piston;
- the axially fixed component is the housing or the idler gear;
- and
- the mechanical engaging element is a sphere or a ball.
