Abstract

The invention discloses a transmission gear selecting and shifting control device driven by single motor. The device comprises a gear selecting and shifting shaft, a driving motor, a planet gear speedreducing device and a limiting and detecting device, wherein the driving motor is connected with the planet gear speed reducing device; the planet gear speed reducing device is connected with the gear selecting and shifting shaft; the limiting and detecting device is arranged on the gear selecting and shifting shaft; the planet gear speed reducing device comprises a gear ring, and a planet gear mechanism and a power locking mechanism arranged on the gear ring; the gear ring is connected with the gear selecting and shifting shaft; the planet gear mechanism is connected with the driving motor and the gear selecting and shifting shaft; and the limiting and detecting device comprises a limiting mechanism, and an all-gear position signal detecting module arranged on the limiting mechanism. Thedevice adopts single-motor structure and the planet gear mechanism to achieve two functions of gear selection and gear shifting through single power inputting and the functions of speed reduction andtorque increment, is compact in overall structure and lower in cost, and can be widely applied to the transmission gear selection and shifting.

Description

technical field [0001] The invention relates to a technique in the field of gear selection and shifting of a transmission, in particular to a gear selection and shifting control device for a transmission driven by a single motor. Background technique [0002] Due to its high efficiency, low cost and short development cycle, the automatic mechanical transmission (AMT) has gradually gained the attention of the automotive industry. The shifting device of AMT is its key core technology. Under the development trend of electrification, the shifting device of electric drive mode is more and more widely used. Contents of the invention [0003] The present invention aims at the defect that the function of the prior art is relatively single, and proposes a single-motor-driven transmission selection and shifting control device, which adopts a single-motor structure and a planetary gear mechanism, and realizes a single power input to complete two functions of gear selection and shifti...
