Abstract
A shift drive including an actuating mechanism, a rack, and a gear housing. The actuating mechanism is driven by a driving mechanism. The rack is linked with the actuating mechanism. The rack includes a connection portion connected to the actuating mechanism through a connecting member 301 The gear housing is provided with an induction gear that meshes with the rack. The gear housing includes a track slot includes a take-up release section and a straight rail section, and an end portion of the rack is capable of a recoverable deformation that can slide in or out of the take-up release section and the length of projection of the take-up release section on an extension line in the direction of the length of the straight rail section is less than the length of the track thereof.
Claims20
A shift drive comprising:
- an actuating mechanism capable of being driven by a driving mechanism;
- a rack linked with the actuating mechanism, at least one end of the rack being capable of a recoverable deformation, the rack including a connection portion and the connection portion being connected to the actuating mechanism through a connecting member;
- and
- a gear housing including a track slot that receives the rack therein, the track slot includes a straight rail section and a take-up release section, wherein an end portion of the rack is capable of a recoverable deformation that slides in or out of the take-up release section,
- wherein the take-up release section includes a first curved end being positioned at a first end of the straight rail section of the track slot and a second curved end being positioned at a second end of the straight rail section of the track slot, and
- wherein a length of the straight rail section is set such that the connection portion can only slide freely therein along with the actuating mechanism.
A shift drive comprising:
- an actuating mechanism capable of being driven by a driving mechanism;
- a rack linked with the actuating mechanism, at least one end of the rack being capable of a recoverable deformation, the rack including a connection portion and the connection portion being connected to the actuating mechanism through a connecting member;
- and
- a gear housing including a track slot that receives the rack therein, the track slot includes a straight rail section and a take-up release section, wherein an end portion of the rack is capable of a recoverable deformation that slides in or out of the take-up release section,
- wherein the take-up release section includes a first curved end being positioned at a first end of the straight rail section of the track slot and a second curved end being positioned at a second end of the straight rail section of the track slot, and
- wherein the gear housing is provided thereon with a gear cover adapted thereto, and the gear cover is provided thereon with an elongated opening of which the connecting member extends out.
A shift drive comprising:
- an actuating mechanism capable of being driven by a driving mechanism;
- a rack linked with the actuating mechanism, at least one end of the rack being capable of a recoverable deformation, the rack including a connection portion and the connection portion being connected to the actuating mechanism through a connecting member;
- and
- a gear housing including a track slot that receives the rack therein, the track slot includes a straight rail section and a take-up release section, wherein an end portion of the rack is capable of a recoverable deformation that slides in or out of the take-up release section,
- wherein the take-up release section includes a first curved end being positioned at a first end of the straight rail section of the track slot and a second curved end being positioned at a second end of the straight rail section of the track slot, and
- wherein the driving mechanism comprises a motor, the gear housing is provided with a magnetic field sensing element at a position corresponding to an induction gear, and the magnetic field sensing element and the motor are in signal connection to a central control unit of an automobile.
