Automobile electronic automatic gear changer

Abstract

The invention provides an automobile electronic automatic gear changer, comprising a support body component, a gear changing arm component, a solenoid valve assembly, an electronic control unit, a gear panel, a handle component, a swing arm and rotating shaft assembly, a manual unlock device and unlock spring and an upper support and sliding pad component. The support body component comprises a support body provided with content cavity, the gear changing arm is arranged in the content cavity, the solenoid valve assembly is arranged at the lower part of the content cavity; the electronic control unit is arranged at the outside of the support body, the upper support is fixed at the upper part of the support body; the gear panel is blocked and connected on the upper support; the handle component is connected on the gear changing arm component; the swing arm and rotating shaft assembly is arranged on the outer sidewall of the support body, the traverse pin at the lower end of the of swingarm is in sliding fit connection with the connecting sleeve on the solenoid valve assembly; and the manual unlock device and unlock spring are arranged on the sidewall of the content cavity of the support body. The electronic automatic gear changer of the invention has the advantages of good hand feel, compact structure, convenient installation position selection and the like.

Description

technical field [0001] The invention belongs to the automobile shifter technology. Background technique [0002] The shifter of the automatic gear car sold on the automobile market now all adopts traditional flexible shaft (cable) or hard shaft mode on the connection with the transmission box and the gear shift transmission output. [0003] The structural characteristics of these two methods are as follows: [0004] 1. Hard shaft connection: A metal hard rod or steel pipe is used to mechanically connect the shifter and the gearbox. This type of structural form has mature technical conditions and mostly appeared on early automatic transmission vehicles. [0005] Advantages: The connection between the shifter and the gearbox is very reliable, there is no loss of efficiency on the output of the shift stroke, the transmission is fast, and the service life is long. The whole mechanism is composed of three parts: the shifter, the control shaft and the reinforcing rod; [0006] ...

AI Technical Summary

Problems solved by technology

[0006] Disadvantages: The installation steps of the shifter are cumbersome, most of the parts are made of metal, the overall volume is large, the weight of the parts is heavy, the manufacturing steps are cumbersome, and the process is complicated; the hand feeling is poor when using; the environment layout design of the whole vehicle is very harsh; It is very difficult to manufacture the cockscomb tooth injection mold when the gear is manufactured, and it is also very difficult to maintain and replace in the later stage

[0009] Disadvantages: Due to the impact of the stroke load efficiency when the flexible shaft is working, the actual output of the shifter's stroke is different from the actual required stroke of the gearbox. The shifter is designed with high work intensity, and the manufacturing mold of the cockscomb teeth is difficult to process; When in use, due to the friction of the flexible shaft itself, the hand feeling of the shifter is average when operating; the efficiency in stroke transmission is low
