Operation principle of the present utility model is:Refering to accompanying drawing 7a, in the braking procedure of advance operating mode, in wheelcylinder piston 12
Under the effect of hydraulic coupling F1, the axial movement of inside brake block compresses brake disc, and outer brake block is also pressed in the presence of hydraulic pressure reaction force
Tight brake disc.Simultaneously piston 2 is moved rearwards by along inside brake block, and in wavy surface, as shown in Figure 7b, hydraulic circuit oil pressure slightly has
Raise.In the presence of brake disc torque, inside brake block is moved forward and produces horizontal applied force F2, forward bolt piston to forward bolt piston
It is compacted, acted on by power F3 along pipe interface direction, hydraulic circuit oil pressure raises hydrodynamic force P, and rear end piston is forced out,
Acted on inside brake block by wavy surface, as shown in Figure 7 c, because piston 2 is in axially 45 ° of angles with place face along brake disc,
Understand that inside brake block backboard rear end is acted on by power F4 according to the simplification of power, understand that inside brake block rear end produces by force resolution
Axial reinforcement F6, while horizontal force F5 can promote inside brake block to travel forward again so that forward bolt piston continues to compress, and so follows
Ring, until automobile stagnation of movement or piston movement are to extreme position.After releasing braking, after wheelcylinder piston 12 resets, in the work of force transmission element
With under, the complete return of inside and outside brake block.In sternway operating mode, its operation principle is similar to advance operating mode.
Refering to Fig. 4, during braking, inside brake block promotes piston 2 to move, the sword side of piston packing 3 under rubbing action with
Piston 2 is moved, and makes piston packing 3 produce elastic deformation, is equal to corresponding to the ultimate deformation amount of the sealing ring of threshold friction
The stroke of piston medial slope and pipe interface medial slope.When releasing braking, brake block is axially return, and piston 2 is from wavy surface
Exit, set back.Simultaneously front and back end piston is return under the resilient force of piston packing 3, the complete return of brake block.
In this patent, the number of pistion recess can be with multiple, but will be respectively about inside brake block backboard and brake-caliper support
In front and back the center line of side parallel surface is symmetrical, and no more than the size of contact surface.Simultaneously the diameter of piston is different, piston
The waveform of contact surface has a difference in groove, but other require it is constant.
