Abstract

The invention is applicable to the technical field of transmissions, and provides a gap adjusting mechanism for a gear selecting component of a gearbox. The mechanism comprises a shell and a motor, and a coupler, a lead screw and a sealing block are arranged in the shell; an output shaft of the motor is in transmission connection with the lead screw through the coupler, the lead screw is in threaded connection with a sealing plug block, the sealing plug block is located in a concave hole in the shell, an elastic check ring is further installed between the sealing plug block and the coupler, the sealing plug block is in a circular ring shape, the concave hole is a round hole, external threads are arranged on the peripheral face of the sealing plug block, and internal threads matched with the external threads are arranged in the concave hole. The mechanism reduces the workload in the assembly process, and is beneficial to the batch production of the full-motor-driven transmission.

Description

technical field

[0001] The invention relates to the technical field of transmissions, in particular to a gap adjustment mechanism and a transmission used for gear selection components of a transmission. Background technique

[0002] Electromechanical automatic transmissions are upgraded from traditional manual transmissions, which not only achieve high fuel economy and low emissions, but also inherit the advantages of high efficiency, high reliability, low cost, and simple structure of manual transmissions. The selection and shifting mechanisms in electromechanical automatic transmissions are driven by full motor drive, pneumatic drive mechanism, hydraulic drive mechanism, electro-hydraulic drive mechanism, etc.

[0003] Among them, the all-motor-driven transmission uses the motor as the driving part to perform the gear selection action. The output shaft of the motor drives the connecting screw through the coupling, and the screw nut is screwed on the screw. The motor drives...
