Generally speaking, after the disc hydraulic brake plunger receives the brake fluid pressure effect, promote rack-mount braking plate and move to brake disc, brake disc is received the surface friction drag of braking plate in the other direction, forces brake disc to stop the rotation, and stops fully until automobile.When hydraulic coupling is cancelled, piston return backward under the effect of rectangular loop, piston are applied to that thrust on the braking plate disappears, surface friction drag disappears the automobile brake off.Since then, the be hit by a bullet effect of reed of working state is that braking plate plays guiding, support and brakes cushioning effect when on spring sheet, sliding in automobile brake and recovery process.But because in the driving braking process, work under bad environment, impurity such as often water stain, dust with pH value; After automobile was parked for a long time, the brake disc corrosion was after starting the braking automobile function once more; Because rusty stain and impurity cause brake disc and braking plate to defend and can not be separated from fully; After piston thrust disappeared, braking plate can not be retreated, and formed the tray phenomenon.Simultaneously, the brake structural of existing technology also can make piston in the return process, because the power that brake disc forms in rotary course forces brake disc that friction plate is had certain power of dishing out, and causes the braking plate return inhomogeneous, forms the eccentric wear phenomenon.
Summary of the invention
The purpose of the utility model is exactly will provide a kind of and be installed in the break, make break that the brake spring device of stroke eccentric wear and tray phenomenon can not take place.
For realizing above-mentioned purpose; The brake spring device that the utility model designed comprises the spring matrix, and two ends respectively are provided with a spring hook pawl on the said spring matrix; The spring hook pawl is folding shape structure, and the circular arc baffle plate of said spring hook pawl one end is connected with the spring matrix.
Further, the folding shape structure position of said spring hook pawl is the wide circular arc of R shape, like this can proof strength, and avoid stress to concentrate again.
Further, the termination of the other end of said spring hook pawl is little arc structure; There is dome the lower end of said little arc structure.This uses this structure after making that braking plate weares and teares, and alarm when automobile brake and releasing on the braking plate and spring sheet slide steadily, the noise free appearance.
Again further, between wide circular arc and termination, having leniently, the circular arc place is the gradual structure of dwindling to the termination; Said termination with gradual dwindle be between the structure folding shape be connected.This makes total excessively even, thereby can guarantee that again the elastic force of spring is enough when practicing thrift section bar.
Compared with prior art; The advantage of the utility model is: the spring hook pawl that respectively establish at spring matrix two ends, be installed on the alarm of inside and outside braking plate of break, and can guarantee that the equilibrium of forces that is applied to inside and outside braking plate distributes; Thereby not having the eccentric wear phenomenon takes place; And when its return was bad, the elastic force that applied spring colludes after the pawl compressive strain forced braking plate to force return, also the tray phenomenon can not take place.Simultaneously; Utilize the circular arc baffle plate of spring hook pawl one end to be connected with the spring matrix, fixedly the inside and outside shift length of braking plate has prevented that braking plate is under the elastic force of spring hook pawl; Be close to piston end surface and caliper body arc transition; Thereby after the braking plate wearing and tearing, prevent that the automobile brake displacement is bigger, cause braking force not enough.
