Problems solved by technology

At present, the technology of gear selection and shifting actuators can be divided into three types: pneumatic, hydraulic and electric. The advantage of high control precision, but requires an external oil source system, high cost, complex structure and difficult to arrange; the shift force provided by the motor is small, but it has the advantages of simple structure, precise control, high transmission efficiency, and low production cost. The motor-driven gear selection and shifting actuator is undoubtedly the development trend of AMT technology

Abstract

The invention discloses a motor type gear selecting and shifting actuator assembly, and belongs to the technical field of automatic transmissions. The assembly aims to solve the problems that the gear shifting force provided by motor gear shifting is small and the utilization rate of output torque of existing motor type gear selecting and shifting actuators is low. The assembly mainly comprises a shell, motors, ball screws, sensors, a gear selecting and shifting head and a gear shifting shaft, wherein the two motors are arranged in parallel and drive gear selecting movement and gear shifting movement respectively, and the ball screws are connected to the motors to change rotational motion of the motors into linear motion of the gear selecting and shifting head. According to the assembly, the output torque of the motors can be fully utilized. The assembly has the advantages that the structure is compact, the transmission efficiency is high, the response speed is high and control is accurate.

Description

technical field [0001] The invention belongs to the technical field of automatic transmissions. Background technique [0002] Currently, due to the control requirements of Automatic Mechanical Transmission (AMT) and the performance requirements of the transmission, gear selection actuators are widely used. [0003] The gear selection actuator is an important executive component of the AMT transmission. The transmission control unit (TCU) judges the vehicle status and issues a gear shift command. The gear selection actuator is responsible for receiving the command and executing the gear shift action, and at the same time feeds back the gear information to the TCU. At present, the technology of gear selection and shifting actuators can be divided into three types: pneumatic, hydraulic and electric. The advantage of high control precision, but requires an external oil source system, high cost, complex structure and difficult to arrange; the shift force provided by the motor is...
