Abstract
Disclosed a bidirectional driving disc brake comprises a disc-brake disc and a brake clamper. Wherein, the two sides of jaw of brake clamper have left and right friction plates while one friction plate is inside the clamp arm, and another one is connected to the driving device; a fixed support holder is mounted on the jaw which is on the side of driving device, and its has a projected table for supporting the inner chamber of casing of driving device and sliding matched with said casing; the driving device has three driving discs and one driving shaft while the driving shaft is drawn by the brake tight-wire to rotate the static disc or rotate two movable discs at one time; the discs can realize axial driving via the spiral surface or spiral slots arranged on disc surface and the relative rotation of steel ball; and said two movable discs are individually rigidly connected to the casing of driving device and friction plates. The invention utilizes the bidirectional driving theory of driving disc to make said two friction plates close to the disc at one time in the brake process of disc brake and clamp the disc.
Description
Technical field
The present invention relates to the brake equipment of a kind of bicycle, three-wheel vehicle, light-duty power car, particularly a kind of disc brake with bi-directional drive structure.
Background technology
Disc brake comprises stop sincere caliper and brake disc, in the sincere caliper of stopping actuating device and friction lining is housed, and it is fixedly connected on the vehicle frame relevant position, and the brake disc is fixedly mounted on the wheel hub.At present, in the domestic and international various mechanical type disc brake product, actuating device in its sincere caliper of stopping is owing to be subjected to the spoke of wheel and the too small influence of available space between the disc brake hull, mostly adopt the unidirectional drive structure, drive friction lining by the spiral camber on the driving disk end face and hold the realization braking tightly with the brake disc.Therefore, the outstanding problem of current reflection is: moments two friction lining before brake is not to contact disc simultaneously, but under the driving of unidirectional drive dish, a slice friction lining is pressed in earlier on the disc end face, then under the application force of unidirectional drive dish, the strength that forces disc to produce elastic deformation or overcome the pull back spring that floats in the floating bracket under the application force of disc self rigidity makes caliper displacement vertically, until with just realize braking after the another side friction lining contact.So its brake hull of the mechanical type disc brake of unidirectional drive is long-term work under the effect that is subjected to cooresponding axial force, disc is owing under the effect of for a long time frequent axial force, aggravate the face runout amount of disc, i.e. disc rolling momentum strengthens, friction lining occurs and rub the disc phenomenon, produce and drag moment.People are by bike or during Electrical Bicycle, the consumption that can strengthen manpower or electric energy, in addition, because actuating device glancing impact two friction linings do not contact with disc simultaneously, so two friction plate abrasion degree differences influence the durability of disc brake.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of mechanical type disc brake of realizing bi-directional drive under the effect of mechanical force, thereby has reached desirable braking effect.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of bidirectional drive disc brake, it comprises disc brake dish and brake binder, brake binder is provided with the jaw that holds the disc brake dish, and left and right sides friction plate assembly is equipped with on the jaw both sides, is provided with V-arrangement return leaf spring between two friction plate assemblies, one of them friction plate assembly is contained in the tong arm, another friction plate assembly and actuating device join, and the housing and the tong arm of actuating device are fixed with one, and are characterized in:
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 firm 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 Moving plate 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 driving with rotating 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.
