Control device for reverse gear self-locking

Abstract

The self-locking back gear control device includes one right box, one gear shifting drum, one gear shifting positioning board on the gear shifting drum and with limiting salient point or notch, one gear shifting shaft assembly and one stopper assembly to control the position of the gear shifting positioning board. The right box has hinged back gear rocking arm and back gear operation mechanism to control the back gear rocking arm, and the back gear rocking arm has one end matching the limiting salient point or notch and the other end connected to the right box through one limiting spring. The present invention can avoid malfunction, and has the advantages of simple structure, convenient operation, high safety and reliability, low cost and other advantages.

Description

technical field [0001] The invention relates to a reverse gear control device in a motor vehicle engine transmission system, in particular to a reverse gear self-locking control device in an all-terrain beach car and a go-kart engine transmission system. Background technique [0002] At present, in addition to the specially designed CVT engine, the reverse gear control device in the all-terrain ATV and go-kart engine transmission system of the prior art generally has two structural forms, namely an external type and a built-in reverse gear control device; The gear control device is to install the reverse gear assembly and its control device outside the engine, and the inside of the engine will not be changed. Although the reverse gear operation of this device is reliable, the structure is complex, there are many parts, the cost is high, and it affects the appearance of the whole machine; When the vertical engine is used as the power system of the all-terrain ATV or go-kart e...

Problems solved by technology

[0002] At present, in addition to the specially designed CVT engine, the reverse gear control device in the all-terrain ATV and go-kart engine transmission system of the prior art generally has two structural forms, namely an external type and a built-in reverse gear control device; The gear control device is to install the reverse gear assembly and its control device outside the engine, and the inside of the engine will not be changed. Although the reverse gear operation of this device is reliable, the structure is complex, there are many parts, the cost is high, and it affects the appearance of the whole machine; When the vertical engine is used as the power system of the all-terrain ATV or go-kart engine, the built-in reverse gear control device is to add a reverse gear to the cycle shift device. The structure of the device is simple and easy to operate, but it is easy to operate Misoperation occurs, for example, when moving forward, due to a misoperation that causes the gear to be shifted too quickly and then shifted to the reverse gear, the engine will be damaged by a violent impact, thereby affecting the safety of the machine and the operator

For this reason, many scientific research institutions, manufacturers and people of insight have continuously carried out development and research on the above-mentioned problems, but there is no better improvement method so far.
