Problems solved by technology

This kind of screw drive assembly has a complex structure, takes up a lot of space, has a lot of vibration, and has a high cost.
Moreover, the shift-by-wire actuator cannot provide real-time feedback on the current position of the shift rocker arm, that is, it cannot recognize the current gear position in real time, and cannot feed back the real-time situation to the GSM (shift control module), and the controller cannot perform real-time control corrections on the drive mechanism , there will be a certain error in the system, and the precise control of the driving mechanism cannot be realized, so that the precise control of the shift actuator cannot be carried out

Embodiment Construction

[0038] Embodiments of the present invention are described in detail below:

[0039] Such as Figure 1 to Figure 5 As shown, a shift actuator includes an actuator housing 100, a drive mechanism 200 disposed in the actuator housing 100, a transmission structure connected to the drive mechanism 200 and connected to the transmission shift shaft 10 , and a position detection mechanism 600 arranged on the actuator housing 100 and connected with the transmission structure. The driving mechanism 200 drives the transmission structure to run, thereby driving the transmission shift shaft 10 connected to the transmission structure to rotate, so as to realize the shifting function. During the shifting process, the rotational position of the shift shaft 10 can be detected in real time by the position detection mechanism 600 to identify the current gear position in real time, and the real-time situation can be fed back to the GSM (shift control module), and the controller can perform real-t...

Abstract

The invention provides a gear shifting executor. The gear shifting executor comprises an executor shell, a driving mechanism, a transmission structure and a position detection mechanism. The driving mechanism is arranged in the executor shell, the transmission structure is connected with the driving mechanism and a gear shifting shaft of a transmission, and the position detection mechanism is arranged on the executor shell and connected with the transmission structure. The transmission structure comprises a synchronous belt transmission mechanism, a worm gear transmission mechanism and a gear transmission mechanism. The synchronous belt transmission mechanism is connected with the driving mechanism, the worm gear transmission mechanism is connected with the synchronous belt transmission mechanism and parallel to the driving mechanism, and the gear transmission mechanism is in close connection with the worm gear transmission mechanism. The gear shifting shaft of the transmission and the position detection mechanism are arranged on two sides of the gear transmission mechanism respectively. The gear shifting executor has advantages of structural compactness, small space occupancy, reliability in operation, low vibration and accuracy in control.

Description

technical field [0001] The invention relates to the technical field of shift control of automatic transmissions of automobiles, in particular to a shift actuator. Background technique [0002] The drive-by-wire operation and control mechanism of automobiles is a direction of future development. The shift-by-wire actuator is a mechanical and electronic integrated mechanism device used to control automatic transmissions for PRNDS (or other types) gear switching. In the traditional technology, the transmission mechanism of the shift actuator is mainly driven by a screw assembly, which converts the rotation of the drive mechanism into a linear motion along the axis of the screw, and then converts the linear motion into the swing of the shift rocker arm through the connecting rod. This screw drive assembly has a complex structure, takes up a lot of space, has a lot of vibration, and has a high cost. Moreover, the shift-by-wire actuator cannot provide real-time feedback on the cu...
