The jaw place that is positioned at actuating device one side is provided with a fixing support rack, fixing support rack be provided be supported on actuating device housing inner chamber and with the boss of the mutual bearing fit of housing,
Actuating device is provided with the axle drive shaft that three driving disies and a butt head are equipped with rocking arm, middle driving disk is a price fixing, the both sides driving disk is a Moving plate, axle drive shaft drives price fixing and rotates or drive simultaneously the rotation of two Moving plates under the brake cable pulling, helical surface by being arranged on card between two Moving plates and the price fixing or plug helix add that relative rotation of steel ball realize axially driving, and two Moving plates contact with actuating device housing, friction plate assembly rigidity respectively.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, for preventing to relatively rotate between fixing support rack and the housing, be provided with inhibiting device between fixing support rack and the housing, inhibiting device can adopt two bolts to add the structure of retracing spring and slide opening cooperation.
The technical problem to be solved in the present invention can also come by the following technical programs to realize that further axle drive shaft is connected driving with price fixing that the card of two Moving plates is provided with and corresponding helical surface of price fixing card or plug helix, between price fixing and the Moving plate steel ball is housed.
The technical problem to be solved in the present invention can also be come further realization by the following technical programs, and the housing inner face die casting of joining with actuating device has the ball-and-socket that holds steel ball, and then the housing inner face constitutes the Moving plate that cooperates with price fixing, and axle drive shaft is connected driving with price fixing.
The technical problem to be solved in the present invention can also be come further realization by the following technical programs, and the boss of price fixing and fixing support rack is fixed with one, and two Moving plates are connected with axle drive shaft realizes the moment of torsion transmission, and price fixing and axle drive shaft be bearing fit in the axial direction.Axle drive shaft is set to multi-faceted column, and two Moving plates are provided with multiaspect shape hole, and Moving plate can only be done longitudinal travel and not turn on axle drive shaft.Also can adopt spline to cooperate.
When brake, drive drive shaft turns by the pulling cable wire, under the effect of price fixing both ends of the surface spiral slide or spiral chute, promote two Moving plates and produce left and right sides longitudinal travel, a Moving plate drives with housing bonded assembly tong arm and moves inward, the friction plate assembly that then is installed in the tong arm is close to disc, and another Moving plate promotes to be installed in another interior sheet friction plate assembly of housing outwards near disc simultaneously, contacts disc simultaneously and clamps disc until two friction plate assemblies and realize braking.After brake finishes, release handle, under the effect of pull back spring, two friction plate assemblies break away from disc simultaneously, the car cruising.The present invention compared with prior art, it utilize the transmission principle of driving disk bi-directional drive make disc brake in braking procedure two friction linings simultaneously to disc near and clamp disc and realize braking, thoroughly eliminate the axial force that in braking procedure, disc is easily produced distortion, reached desirable braking effect.
