Abstract

The invention relates to a speed change box operation device for a special vehicle chassis and aims at providing a follow-up type power assisting gear shifting operation device capable of guaranteeing light and convenient gear shifting, guaranteeing clear gears as well and occupying small installing space. The follow-up type power assisting gear shifting operation device comprises a controller (1), a gear shifting flexible shaft (2), a control valve (4), a gear shifting rocker arm (5) and a power assisting air cylinder (6). The controller is connected with a valve element of the control valve through the gear shifting flexible shaft, and the other end of the valve element is hinged to the gear shifting rocker arm. The other end of the gear shifting rocker arm is hinged to a piston rod of the power assisting air cylinder. The gear shifting rocker arm is used for being fixedly connected with a spline shaft of a speed change box. The control valve is provided with an air inlet, two air outlets and two exhaust ports. The two air outlets of the control valve communicate with the two sides of a cylinder barrel of the power assisting air cylinder through pipelines.

Description

technical field [0001] The invention relates to a transmission control device, in particular to a transmission control device used for special vehicle chassis. Background technique [0002] With the development of technology, commercial vehicles are developing in the direction of high mobility and large carrying capacity. There are more and more heavy-duty gearbox applications, and correspondingly higher requirements will be put forward for the gearbox control system: easy shifting, improving the comfort of operation; high stability, ensuring the reliability of the control system; It has a small shift stroke to ensure clear gear positions. At the same time, due to the limited layout space of the whole vehicle, the space occupied by the control system is required to be as small as possible, and the conventional shift lever system will not be able to be arranged. Therefore, need to design a cover that can solve the above-mentioned problem gear shift manipulation device. Co...
