Bar 16 front end, it is achieved fix the multiple spot connecting fork 17, improves the stability installed, realizes both linkages after installation.
The push rod 16 stable sliding in installing pipe 15 is realized by the two-point locating of fairlead a20 and fairlead b21.
With reference to Fig. 7, in driving cavity 1, install and be additionally provided with a dust cover 25, dust cover 25 between pipe 15 and push rod 16
And installing and can realize installing by jump ring between pipe 15, the other end is set on push rod 16, is preferably provided with on push rod 16 simultaneously
There is a stopper slot 26, be same as connecting and fixing one end of dust cover 25, it is to avoid dust cover 25 is with being intended to sliding on push rod 16.Dust cover
The setting of 25 effectively prevent the foreign bodies such as the dust in the external world and enters into driving from fairlead group in the gap installing pipe 15 inwall
In cavity 1, improve stability and the service life of equipment.
With reference to Fig. 6, lower house 5, diaphragm 7 are fixed by clip 27 with being connected between lid 4, are connected lid 4, diaphragm 7 and upper casing
Fixedly mount again by clip 27 between body 6.
Brake chamber duty: when driving states, is passed through compressed air by trachea 13 in air storing cavity 14, compression
Air push diaphragm 7, after the elastic force of the spring 10 in overcoming driving cavity 1, diaphragm 7 advances push rod 16, the company on push rod 16
Connecing fork 17 promotion and adjust arm realization braking, time at compressed air row, push rod 16 gradually resets, and stops braking.
When driving states enters into parked state, air is drained by the trachea 13 in parking cavity 2, simultaneously spring 10 chamber
Indoor spring 10 resets, and is moved toward push rod 16 direction by the diaphragm 7 on parking cavity 2, and diaphragm 7 promotes push rod 11, push rod 11
Promote the diaphragm 7 in driving cavity 1, final promotion push rod 16, it is achieved the braking to automobile.
When parked state enters into driving states, pressurization in parking cavity 2, the diaphragm 7 in parking cavity 2 is extruded
Resetting, spring 10 continues to be compressed, simultaneously because the spring 10 in driving cavity 1 resets and resetted by diaphragm 7, push rod 11 is by fight back
In situ, push rod 16 contact braking.
More multioperation is the most all known, repeats no more.
Embodiment two, a kind of automobile brake chamber, with reference to Fig. 8, compared with embodiment one, difference is, installs pipe
The front end of 15 is adpting flange 28, and being simultaneously directed to overlap b21 is a screwed hole, is connected by threaded with being connected fork 17.
Specific embodiment is only that it is not to restriction of the present utility model, this area to explanation of the present utility model
The present embodiment can be made after reading this specification by technical staff as required does not has the amendment of creative contribution, but only
All to be protected by Patent Law in right of the present utility model.
