And the height of vehicle can be adjusted according to the instruction of graduated scale, convenient for the adjusting of height of car.
The operating condition of the utility model generally comprises following three kinds: (1) operating condition one: when normal setting height, group of stretching at this time
The clamping section 662 of part 60 is locked, and length is constant, and telescopic component 60 is fixedly connected with air bag bearing beam 160, is jumped with vehicle bridge 120
It moves and control arm 20 is driven to swing, cause the intake valve of altitude valve 240 or vent valve to be opened, to be filled, be put to air bag 220
Gas guarantees that height of car is in position initially set always；Operating condition two: road conditions preferably or get rid of extension demand and need to reduce vehicle
When height, the clamping section 662 of telescopic component 60 is unclamped, shorten corresponding length by graduated scale and is locked again, control arm is driven
20 swing, and the vent valve of altitude valve 240 is caused to be opened, and air bag 220 is deflated, and height of car is down to corresponding position, is reached again
Equilibrium state；Operating condition three: when needing to increase height of car, the clamping section of release telescopic component 60 similar with operating condition two is operated
662, corresponding length is extended by graduated scale and is locked again, is driven control arm 20 to swing, is caused altitude valve inlet open, gas
Capsule inflation, height of car rise to corresponding position, reach equilibrium state again.
In conclusion the utility model proposes air suspension machinery control mechanism, in tradition machinery formula altitude valve control
It is improved on the basis of mechanism processed, key is to have used telescopic component or extension type longitudinal tie, by adjusting longitudinal tie
Length manually adjusts the function of height of car to realize.The mechanical control mechanism is simple and reliable, convenient working, without increasing volume
Outer leveling valve or other electric control elements, it is at low cost, there is broader use space.
