Abstract
A high-pressure flushing vehicle air control speed changing box comprises a box body, wherein a driving shaft and a driven shaft are installed on the box body, a driving gear is arranged on the driving shaft, a driven gear is arranged on the driven shaft, the driven gear and the driving gear are meshed, a meshing sleeve is arranged on the driven shaft, a shifting fork is arranged inside the meshing sleeve, the end portion of the shifting fork is provided with a shifting fork base, and the bottom portion of the shifting fork base is provided with a spring. The high-pressure flushing vehicle air control speed changing box is characterized in that an air cylinder is installed on the box body, and a piston end of the air cylinder is connected with the shifting fork base. The air cylinder is used for controlling gear disengaging and engaging of the speed changing box, automatic controlling is achieved, and therefore the high-pressure flushing vehicle air control speed changing box is simple and convenient to operate, efficiency is greatly improved, control is precise and safety is high.
Description
Technical field
The utility model relates to a kind of gearbox, is specifically related to a kind of high-pressure sewer flushing vehicle gas control gearbox.
Background technique
In the prior art, the gearbox of high-pressure sewer flushing vehicle is installed manual engage a gear mechanism usually, engage a gear needs to carry out under the assistant engine vehicle stop state, operate gear owing to adopt manually mode, sometimes also need rotating drive shaft just can hang up gear, therefore it is very inconvenient to operate, and efficient is low, and dangerous.
Summary of the invention
The purpose of this utility model is defective and the deficiency that overcomes prior art, and a kind of automation, easy and simple to handle, high-pressure sewer flushing vehicle gas control gearbox that efficient is high are provided.
For realizing above purpose, technical solution of the present utility model is: a kind of high-pressure sewer flushing vehicle gas control gearbox, comprise casing, driving shaft and driven shaft are installed on the described casing, described driving shaft is provided with driving gear, described driven shaft is provided with driven gear, described driven gear and driving gear are meshed, described driven shaft is provided with the engagement cover, in the described engagement cover shift fork is installed, the end of described shift fork is provided with the shift fork seat, and the bottom of described shift fork seat is equipped with spring, it is characterized in that: on the described casing cylinder is installed, the piston end of described cylinder is connected with the shift fork seat.
Described casing is provided with bearing, and described bearing is installed in the both sides of driving shaft and driven shaft respectively.
It is indoor that the master cock of described cylinder is positioned at car steering.
Compared with prior art, the beneficial effects of the utility model are:
Adopt cylinder to handle the engage a gear that takes off of gearbox, realized the control automation, it is easy and simple to handle, and efficient improves greatly, and precise control is safe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: casing 1, driving shaft 2, driven shaft 3, driving gear 4, driven gear 5, engagement cover 6, shift fork 7, shift fork seat 8, spring 9, cylinder 10, bearing 11.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail.
Referring to Fig. 1, a kind of high-pressure sewer flushing vehicle gas control gearbox, comprise casing 1, driving shaft 2 and driven shaft 3 are installed on the described casing 1, described driving shaft 2 is provided with driving gear 4, described driven shaft 3 is provided with driven gear 5, described driven gear 5 and driving gear 4 are meshed, described driven shaft 3 is provided with engagement cover 6, in the described engagement cover 6 shift fork 7 is installed, and the end of described shift fork 7 is provided with shift fork seat 8, the bottom of described shift fork seat 8 is equipped with spring 9, on the described casing 1 cylinder 10 is installed, the piston end of described cylinder 10 is connected with shift fork seat 8, and it is indoor that the master cock of described cylinder 10 is positioned at car steering.
Described casing 1 is provided with bearing 11, and described bearing 11 is installed in the both sides of driving shaft 2 and driven shaft 3 respectively.
When needs are put into gear operation, open the master cock in the operator cabin earlier, pressurized air enters in the cylinder 10, and the piston end of cylinder 10 promotes 8 motions of shift fork seat, shift fork seat 8 can drive shift fork 7 and move upward, pry open engagement cover 6, make driven shaft 3 and driven gear 5 separately, finish gear shift operation, after gearshift is finished, cylinder 10 unloads power, and shift fork seat 8 drives shift fork 7 and gets back to original position under the spring-back force effect of spring 9, thereby makes driven shaft 3 and driven gear 5 to combine again.
