Novel electronic gear shifting execution structure

Abstract

The invention relates to the technical field of automobile electronic gear shifting actuators, in particular to a novel electronic gear shifting execution structure. The novel electronic gear shiftingexecution structure comprises a lower shell and an upper shell, a control circuit board and a speed reduction assembly are arranged between the lower shell and the upper shell, the speed reduction assembly comprises a direct-current motor, a first-stage speed reduction gear, a second-stage speed reduction gear, a third-stage speed reduction gear, a fourth-stage speed reduction gear and a gear shifting shaft adapter, the first-stage speed reduction gear is connected with the direct-current motor, the second-stage speed reduction gear is meshed with the first-stage speed reduction gear, the third-stage speed reduction gear is meshed with the second-stage speed reduction gear, the fourth-stage speed reduction gear is meshed with the third-stage speed reduction gear, and the gear shifting shaft adapter is meshed with the fourth-stage speed reduction gear. The purpose of amplifying the torque of the direct-current motor is achieved through speed reduction of the fourth-stage speed reduction gears, and a gearbox is driven to shift gears. The novel electronic gear shifting execution structure has the beneficial effects of compact structural design, small volume, less parts, light productweight and low cost.

Description

technical field [0001] The invention relates to the technical field of electronic shift actuators for automobiles, in particular to a novel electronic shift execution structure. Background technique [0002] In order to save space, reduce weight, improve driving comfort, and the demand for artificial intelligence driving, more and more vehicles use full electronic shift systems to replace traditional mechanical shift systems. The system is mainly composed of electronic shifter, transmission control module and electronic shift execution structure. [0003] At present, most of the shifting execution structures used in automotive electronic shifting mechanisms use machined metal gears, so that the processing and manufacturing costs of parts are high, the number of parts is large, and assembly is difficult, which is not conducive to low-cost mass production; in order to increase the reduction ratio , to increase the output torque, many designs have to use worm gear reduction, w...
