Abstract
The utility model discloses a gear shift booster belongs to pneumatic power assisting device's technical field. The gear shifting booster comprises a double-acting cylinder (1) and a direction control valve (2), wherein air holes (11) and (12) of two chambers of the double-acting cylinder (1) are respectively connected with a first air outlet (21) and a second air outlet (22) of the direction control valve (2) through a pipe (3), an air inlet (23) of the direction control valve (2) is connected with a compressed air source, a piston rod (4) of the double-acting cylinder (1) is linked with a gear shifting rod of a gearbox, and a valve rod (5) of the direction control valve (2) is linked with a gear shifting hand rod. The gear shifting hand lever operates the direction control valve through a valve rod linked with the gear shifting hand lever to control the air inlet direction of the double-acting air cylinder, a compressed air source enters the double-acting air cylinder to push the piston rod to move, and the piston rod pushes and pulls the gear shifting rod of the gear box to complete gear shifting operation so as to play a role in gear shifting assistance. The utility model discloses simple structure, convenient assembling, the maintenance is simple and easy.
Description
Technical field
The utility model belongs to the technical field of air assisted device, specifically is meant the gear shift servo-unit that a kind of big-and-middle-sized gear automobile gear-box gear-shifting is used.
Background technology
At present, chaufeur needs could realize with bigger strength the shift operation of change speed gear box when driving big-and-middle-sized automobile.For alleviating the burden of chaufeur, between gear shift hand lever and gearbox gear-shift bar, be equiped with the gear shift servo-unit, to play the power-assisted effect.The control cock of the power-assisted cylinder of existing gear shift servo-unit and control airintake direction combines, and has complex structure, manufacturing cost height, shortcomings such as inconvenient maintenance.
The utility model content
The purpose of this utility model is to provide gear shift servo-unit a kind of simple in structure, easy to maintenance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: double-acting cylinder and directional control valve, the pore of two chambers of double-acting cylinder is connected with second air extractor duct with first air extractor duct of directional control valve respectively by pipe, the admission port and the compressed gas source of directional control valve join, the piston rod of described double-acting cylinder and the interlock of gearbox gear-shift bar, the valve rod of described directional control valve and the interlock of gear shift hand lever.
Owing to adopted above-mentioned structure, the gear shift hand lever by with the valve rod direction of operating control cock of its interlock, the airintake direction of control double-acting cylinder, compressed gas source enters in the double-acting cylinder, promote piston rod movement, piston rod push-and-pull gearbox gear-shift bar is to finish gear-change operation, to play the effect of gear shift power-assisted.Control cock of the present utility model and cylinder are divided into two independent sectors, and it is simple in structure, and is easy to assembly, easy to repair.
Description of drawings
Fig. 1 is the constructional drawing of gear shift servo-unit.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail, but does not constitute any restriction of the present utility model.
As shown in Figure 1, gear shift servo-unit described in the utility model, comprise double-acting cylinder 1 and directional control valve 2, the pore 11,12 of two chambers of double-acting cylinder 1 is connected with second air extractor duct 22 with first air extractor duct 21 of directional control valve 2 respectively by pipe 3, the admission port 23 and the compressed gas source of directional control valve 2 join, described directional control valve 2 is a two-position five-way valve, also has two exhausr ports 24,25.The piston rod 4 of described double-acting cylinder 1 and the interlock of gearbox gear-shift bar, the valve rod 5 of described directional control valve 2 and the interlock of gear shift hand lever.
When valve rod 5 pushed away forward, first air extractor duct 21 was communicated with exhausr port 24 with admission port 23, second air extractor duct 22, and pressurized air enters in the chamber of cylinder 4 rear ends, and the gas of front end chamber is discharged from exhausr port 24 simultaneously, piston advances forward, and piston rod 4 travels forward.When valve rod 5 pulled back, first air extractor duct 21 was communicated with admission port 23 with exhausr port 25, second air extractor duct 22, and pressurized air enters in the chamber of cylinder 4 front ends, and the gas of rear end chamber is discharged from exhausr port 25 simultaneously, and piston moves backward, and piston rod 4 moves backward.
The gear shift hand lever by with the valve rod 5 direction of operating control cock 2 of its interlock, the airintake direction of control double-acting cylinder 1, to promote piston rod 4 motions, piston rod 4 push-and-pull gearbox gear-shift bars are to finish gear-change operation, to play the effect of gear shift power-assisted.Control cock of the present utility model and cylinder are divided into two independent sectors, and it is simple in structure, and is easy to assembly, easy to repair.
Claims (2)
1. gear shift servo-unit, it is characterized in that: comprise double-acting cylinder (1) and directional control valve (2), the pore (11) of two chambers of double-acting cylinder (1), (12) are connected with second air extractor duct (22) with first air extractor duct (21) of directional control valve (2) respectively by pipe (3), the admission port (23) of directional control valve (2) joins with compressed gas source, the piston rod (4) of described double-acting cylinder (1) and the interlock of gearbox gear-shift bar, the valve rod (5) of described directional control valve (2) and the interlock of gear shift hand lever.
