The brake can flexibly select the installation space through the structure design of the four-bar linkage during installation, effectively solve the problems of insufficient installation space and difficult installation of the brake device, enhance the work efficiency of the integral vehicle assembly and maintenance, enable the vehicle integral structure to be compact, reduce the integral vehicle volume, and is suitable for light vehicles of motorcycles and the like.
Description
Technical field
The utility model relates to a kind of motor Brake for vehicle, particularly a kind of four-bar mechanism hydraulic pressure disc brake drg.
Background technology
Drg is the requisite safety device of motor bike, is related to the safe operation of motor bike.Drg is fixedly mounted on the vehicle frame of motor bike, by manpower or other power drivens, finishes brake.The disc brake drg is owing to have sensitivity, be difficult for locking and safety advantage of higher, and the use of disc brake is more and more universal, the commonplace motor bike that is applied to.
The installation of disc brake drg is for reducing car load volume and make the flexible action of brake gear that light-duty vehicles such as important influence, particularly motor bike all be arranged, whether compact normal brake application and the safe operation that all is related to vehicle of the size of volume and structure.
In the prior art, in the back hydraulic pressure disc brake of motor bike, the navigating mate pin is stepped on brake pedal, and back brake rod rotates around fix shaft, gives disc brake total pump piston bar motion and transmission of power, and piston rod promotes piston motion, finishes brake.This drive mechanism must have enough spaces to be used for installing the disc brake master cylinder in the direction that back brake rod resistance arm rotates; And brake rod generally all is installed in the chain stay bottom behind the motor bike, and chain stay is comparatively compact with the vehicle frame applying again, and the installing space condition can't be satisfied, the difficulty that causes drg to install, the work efficiency that reduces the car load assembling or keep in repair.
Therefore, need transform, can select installing space flexibly when mounted, can solve the problem that the brake equipment installing space is not enough and installation is difficult, can improve the work efficiency of car load assembling and maintenance the drive mechanism of drg.
The utility model content
In view of this, the purpose of this utility model provides a kind of four-bar mechanism hydraulic pressure disc brake drg, can select installing space flexibly when mounted, actv. solves the problem that the brake equipment installing space is not enough and installation is difficult, improve the work efficiency of car load assembling and maintenance, since optional installing space, the vehicle compact overall structure, reduce the car load volume, be applicable to light-duty vehicle uses such as motor bike.
Four-bar mechanism hydraulic pressure disc brake drg of the present utility model, comprise disc brake master cylinder, brake rod and drive link, described brake rod is finished brake by the piston rod that drive link drives the disc brake master cylinder, also comprise side link and connecting rod, it is that fulcrum forms lever construction that described brake rod is hinged on the vehicle frame with the hinge-point, the resistance arm of described side link, connecting rod, lever construction and vehicle frame constitute four-bar linkage jointly, and wherein side link and vehicle frame are hinged, and described drive link and four-bar linkage are hinged.
Further, the hinge-point of described side link on vehicle frame is positioned at power arm one side of lever construction fulcrum;
Further, described drive link is hinged on the side link of four-bar linkage;
Further, described four-bar linkage is a quadric linkage, and described vehicle frame is as the quarter butt of quadric linkage;
Further, described disc brake drg is the rear brake of footbrake, and the power point of described brake rod lever construction is set with brake pedal.
The beneficial effects of the utility model are: four-bar mechanism hydraulic pressure disc brake drg of the present utility model, on the brake power drive path of original back, add four-bar linkage, brake power and move through four bar transmission devices and pass to brake gear, by structure design to four-bar mechanism, can select installing space flexibly, actv. solves the problem that the brake equipment installing space is not enough and installation is difficult, improve the work efficiency of car load assembling and maintenance, brake pedal and vehicle frame all belong to the component part of four-bar linkage, brake rod drives the four-bar mechanism motion under the effect of braking force, because optional installing space, the vehicle compact overall structure reduces the car load volume, is applicable to light-duty vehicle uses such as motor bike.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the four-bar mechanism hydraulic pressure disc brake drg of present embodiment is the rear brake of footbrake, comprise fluid pressure type disc brake apparatus, brake rod 1, side link 5, connecting rod 4 and drive link 2, the fluid pressure type disc brake apparatus comprises disc brake master cylinder 3; Drive link 2 is hinged with the piston rod of disc brake master cylinder 3; It is that fulcrum forms lever construction that brake rod 1 is hinged on the vehicle frame with the hinge-point, and the power point of brake rod 1 lever construction is set with brake pedal 13;
The resistance arm 11 and the vehicle frame of side link 5, connecting rod 4, lever construction constitute four-bar linkage jointly, and brake rod 1 drives drive link 2 by four-bar linkage and disc brake master cylinder 3 is finished brake; Present embodiment midplane four-bar mechanism is with the quadric linkage of vehicle frame as quarter butt, the quadric linkage freedom of movement is relatively large, brake gear can be moved more flexibly, improve the reliability of device, adopt vehicle frame as quarter butt, can economy system taking up room on vehicle frame, can select installing space more flexibly, be more convenient for installing; Certainly, can be the four-bar linkage of other structure also, such as rocker mechanism, can both reach the utility model purpose;
The direction of arrow is the direction of transfer of mechanism kinematic and power among the figure, and F tramples braking force for the driver, as shown in the figure: and the work of mechanism urges piston rod, to realize the trailing wheel braking; With the motor bike is example, because the braking force that sends from chaufeur has added four-bar mechanism to the drive path that promotes the motion of disc brake total pump piston, the disc brake master cylinder just can be installed in the front portion of bottom fork axis, generally speaking beam bending bicycle all can have certain space in the chain stay front portion to the engine suspension place, so just efficiently solves the problem of disc brake master cylinder installing space deficiency.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
