Problems solved by technology

[0003] The problem with manual transmission components is that the driver has to directly operate the gear lever, which is prone to fatigue and even boredom, and direct operation of the gear lever may cause a car accident
[0014] Yet above-mentioned conventional transmission device also has defective unavoidably
The slope on the preset slope has a fixed profile, making it difficult to vary the shifting
In particular, the cam follower is a protruding part on the outer surface of the shift rail, which requires complicated machining processes, and since this shifting device requires changing the structure of the entire shift rail, it is inconvenient
[0015] In addition, the shift fork needs to be returned using a spring, but it is not easy to return the shift fork to its original position quickly and accurately

Abstract

The invention relates to an electronic transmission device for a gearbox assembly of a four-wheel drive vehicle. The electronic transmission device includes: an engine; a camshaft driven by the engine to rotate; a shift rail component separated from the camshaft by a preset distance and parallel to it; installed on the shift rail component and separated from each other by a certain distance The first and second shift forks; a cam fixed around the camshaft and supported by it, which can selectively act on the first or second shift fork on the shift rail member to achieve shifting.

Description

Technical field: [0001] Generally speaking, the present invention introduces an electronic transmission device for a transmission assembly of a four-wheel drive vehicle, especially an electronic transmission device for a transmission assembly of a four-wheel drive vehicle that uses an engine to control the operation of the transmission to realize automatic transmission. Background technique: [0002] Those skilled in the art know that four-wheel drive vehicle transmission components are divided into manual and electric types. For manual transmissions, the driver can switch between shifting modes through manual operations, while electric transmissions use electronic signals to switch drive modes. In addition, the driver can switch the driving mode of the four-wheel drive vehicle by directly operating the gear lever near the driver's console. [0003] The problem with the manual type transmission assembly is that the driver has to directly operate the gear lever, which is pro...
