Problems solved by technology

[0003] It is not difficult to see from the above that since the shift fork shaft is provided with a rack structure that meshes with the shift gear, when the transmission selects gears, the meshing of the shift gear with the rack on the shift fork shaft may cause teeth to collide with each other. risk, which may cause the transmission to have a hidden danger of frequent alarms

Abstract

The invention discloses a gear selecting and shifting actuating mechanism and an automatic transmission and relates to the technical field of transmissions, aiming at preventing the situation that gears collide with each other from occurring during gear selection of the transmission. The gear selecting and shifting actuating mechanism comprises a gear selecting motor, a gear selecting shaft, a gear shifting motor, a gear shifting shaft, a gear shifting block, shifting fork shafts and shifting forks, wherein the gear selecting motor is connected with the gear selecting shaft in a driving way, the gear shifting motor is connected with the gear shifting shaft in a driving way, the gear selecting shaft is connected with the gear shifting shaft through a thread pair, the gear shifting block which can rotate along the circumferential direction of the gear shifting shaft is sheathed on the gear shifting shaft, the shifting fork shafts are arranged below the gear shifting block and are arranged at intervals in parallel along the axial direction of the gear shifting shaft, and a shifting fork is fixedly arranged on each shifting fork shaft. When the gear shifting block rotates along the circumferential direction of the gear shifting shaft, one shifting fork shaft is driven to move along the axial direction of the shifting fork shaft. The gear selecting and shifting actuating mechanism is mainly used in automobile transmissions.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a gear selection and shifting actuator and an automatic transmission with the gear selection and shifting mechanism. Background technique [0002] Nowadays, the transmissions of automobiles mainly include manual transmissions and automatic transmissions, among which the key technology of automatic transmissions lies in its actuators for gear selection. Gear selection and shift actuators generally include hydraulic actuators and electromechanical actuators, among which electromechanical gear selection and shift actuators have higher transmission efficiency, less energy loss, and are more conducive to the fuel economy of the vehicle. An electromechanical gear selection and shifting actuator in the prior art includes a gear selection mechanism and a gear shifting mechanism. The gear selection mechanism includes a gear selection motor, a gear selection shaft, and a gear selecti...
