Technical field
The present invention relates to a kind of braking device for vehicle, particularly a kind of four-bar mechanism brake device.
Background technology
Brake equipment is the requisite safety device of vehicle, is related to the safe operation of vehicle.Brake equipment is fixedly mounted on the vehicle frame of vehicle, by manpower or other power drivens, finishes brake.Because light-duty vehicle structure such as motor bike is comparatively compact mostly, will occur not having correct position that the situation of drg is installed, this just needs a kind of power and movement conduction device, by suitable path brake-force transmission that chaufeur provided to drg.
In the prior art, car brakeing is by back brake rod, drive link direct drive brake gear, finishes brake; Back hydraulic pressure disc brake with motor bike is an example, and 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.Fig. 1 is a prior art brake equipment drive mechanism scheme drawing, and as shown in Figure 1: this drive mechanism must have enough spaces to be used for installing the disc brake master cylinder in the direction of the resistance arm rotation of lever construction; 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 brake equipment to install, even the work efficiency that reduces the car load assembling or keep in repair can't be installed.
Therefore, need transform the drive mechanism of brake equipment, can select installing space flexibly when mounted, can effectively solve 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, be suitable for the requirement of vehicle compact overall structure, and safety action is reliable, stable performance.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of four-bar mechanism brake device, 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 brake device of the present invention, comprise brake gear, brake rod and drive link, described brake rod drives brake gear by drive link and finishes brake, 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 brake gear is the fluid pressure type disc brake apparatus, and described fluid pressure type disc brake apparatus comprises the disc brake master cylinder, and the piston rod of described drive link and disc brake master cylinder is hinged;
Further, described four-bar linkage is a quadric linkage, and described vehicle frame is as the quarter butt of quadric linkage;
Further, described brake equipment is the post brake device of footbrake, and the power point of described brake rod lever construction is set with brake pedal.
The invention has the beneficial effects as follows: four-bar mechanism brake device of the present invention, 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, when mounted 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, reduce the car load volume, be applicable to light-duty vehicle uses such as motor bike.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a prior art brake equipment drive mechanism scheme drawing;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Fig. 2 is a structural representation of the present invention, as shown in the figure: four-bar mechanism brake device is the post brake device of footbrake in the present embodiment, comprise brake gear, brake rod 1, side link 5, connecting rod 4 and drive link 2, in the present embodiment, brake gear is the fluid pressure type disc brake apparatus, and 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 goal of the invention;
Side link 5 is hinged with vehicle frame in the four-bar linkage, and hinge-point is positioned at power arm 12 1 sides of lever construction fulcrum, and the bigger problem of longitudinal space that can avoid brake rod to extend forward causing makes whole brake device structure more compact, is convenient to installation and maintenance; Drive link 2 is hinged on the side link 5 of four-bar linkage, certainly, also can be hinged on other position of four-bar linkage, also can realize goal of the invention;
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 technical scheme of the present invention to be described, although the present invention 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 technical scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
