It is dynamic, meanwhile, adjustable spring starts further to be compressed, and the synchronous belt moment is in exceptionally straight state, and third gear passes through the second axis band
Dynamic second gear, third gear, first bevel gear and second bevel gear rotation；First bevel gear drives simultaneously with second bevel gear
Corresponding third hand tap gear rotation, the direction of rotation of two third hand tap gears are opposite；Two third hand tap gears pass through third axis band
Dynamic corresponding 4th gear rotation, the direction of rotation of two the 4th gears are opposite；Since two the 4th gear installation sites are opposite
And direction of rotation is on the contrary, V-type guide block is bottom-up together to be started to do so two the 4th gears are driven by corresponding spur rack
It moves back and forth, while restoration spring starts to be compressed.Arc brake piece, brake block rack and two the 7th gears are together with V-type
Guide block radially moves back and forth from inside to outside along brake disc；Arc brake piece is along the radial motion process from inside to outside of brake disc, arc
Shape brake block increases the torque of brake disc；6th gear is moved upwards along wedge-shaped tooth socket inclined-plane, while two the 7th gears
It is moved to arc brake piece along the second slide opening；Two the 7th gear compressing arc brake piece deformations so that two the 7th gears
Between the cambered surface of arc brake piece tend to tighten, reduce the contact area of arc brake piece and brake disc, reduce arc brake
Piece is to the pressure of brake disc, and the torque that brake disc is subject to is held essentially constant, to avoid damage of the change in torque to brake disc；
For arc brake piece along during brake disc radial direction ecto-entad returns, arc brake piece reduces the torque of brake disc；Guide rail
Mechanism drives auxiliary body to be moved downward along wedge-shaped tooth socket inclined-plane, while arc brake piece recoverable force makes two the 7th gears
It supports or opposes along the second slide opening and is moved from arc brake piece direction；Two the 7th gears are withdrawn, the arc between two the 7th gears
Brake block deformation gradually restores；Arc brake piece and the contact area of brake disc gradually increase, and arc brake piece is to brake disc
Pressure gradually increases, and the torque that brake disc is subject to is held essentially constant, to avoid damage of the change in torque to brake disc；Whole
During a, brake block rack drives arc brake piece to reciprocatingly slide in the first slide opening under the action of second gear；Work as branch
Support body pushes arc brake piece to contact generation friction with brake disc, and skidding starts；Skidding continues, and hydraulic column passes through branch
Support body continues to press on arc brake piece and is moved to brake disc direction, until automobile stops, skidding terminates.It braked entirely
Cheng Zhong, arc brake piece are axially moved to brake disc not only along rotation shaft of wheel, reciprocatingly slide also along the first slide opening, while with
V-type guide block pumps；The radiating rate of arc brake piece and brake disc can be improved in this way, while mitigating arc brake
The degree of wear of piece and brake disc；The torque that the reciprocating motion of two the 7th gears makes brake disc be born in brake process is basic
It remains unchanged, avoids change in torque to damage caused by brake disc.
At the end of skidding, hydraulic pump is stopped；Hydraulic column drives arc brake piece and brake by supporter
Disk detaches, and returns to initial position；Restoration spring pushes T-type sliding block to return to initial position, while arc brake piece is restored and pushed away
Entire two the 7th gears are moved to withdraw；T-type sliding block passes sequentially through V-type guide block, supporting block drives entire 6th gear to return to initially
Position, skidding terminate.
Relative to traditional brake technique, the present invention further ensures the validity and travel safety of skidding,
Arc brake piece and the service life of brake disc are extended, reduces arc brake piece and brake disc replaces the frequency；Auxiliary body
The reciprocating motion torque that makes brake disc be born in brake process it is identical always, avoid change in torque to caused by brake disc
Damage, to reduce brake system cost；The configuration of the present invention is simple has preferable using effect.
