Compared with prior art, the comprehensive control castor of damping provided by the invention can be realized the comprehensive control of brake wheel and brake direction
System, it is assumed that original state locating for wheel is relaxation state when operation wheel, and wheel braking process is specifically: firmly stirring vehicle
Brake bar is taken turns, the first pivot pin is driven to rotate on gear stand, and then drives the gear rotation on the first pivot pin, gear rotation
The rack gear of engagement is driven to move up, and then the opening link block with carry-over bar lower end moves up, opening link block, which moves up, drives the second axis
Pin moves up, and then first connecting rod is driven to rotate upwards around third pivot pin, and the 4th pivot pin is rotated down around third pivot pin, the 4th pivot pin
It drives second connecting rod to move down, and then the 5th pivot pin of the fixed grafting in second connecting rod lower end is driven to move down, the 5th pivot pin moves down
On the one hand third connecting rod is driven to rotate down around the 6th pivot pin, the rotation of the 6th pivot pin drives the torsion being fixedly attached on the 6th pivot pin
Spring rotation, on the other hand torsional spring will be moved down in the state that tightens, the 5th pivot pin at this time drives pawl spring to move down around the 7th pivot pin,
The 7th pivot pin is mobile to wheel direction in horizontal bar hole simultaneously, and then pawl spring is driven to realize to wheel direction is mobile to vehicle
Wheel braking；Wheel loosens process: loosen wheel braking pull rod, torsional spring reset drive third connecting rod around the 6th pivot pin to
Upper rotation, third connecting rod drive the 5th pivot pin to move up, and then drive pawl spring to move up around the 5th pivot pin, while the 7th axis
Pin is mobile to separate wheel direction in horizontal bar hole, and then pawl spring is driven to loosen vehicle to far from the mobile realization in wheel direction
Wheel, while the 5th pivot pin moves up and also will drive second connecting rod and the 4th pivot pin moves up, by the 4th pivot pin to moving up
It is dynamic that first connecting rod and the second pivot pin is driven to rotate down around third pivot pin, and then opening link block is driven to move down, by opening
Mouth link block band carry-over bar moves down, and rack gear, which moves down, rotates band moving gear, and gear rotation will drive the first pivot pin to turn
