Abstract
The invention discloses a hydraulic transmission mechanism of a motorcycle rear disc brake, comprising a pushing bar, wherein one end of the pushing bar is connected with a main hydraulic pump. The hydraulic transmission mechanism is characterized in that the main hydraulic pump is connected with and located on a motorcycle frame by a small support plate and is slightly inclined rightwards along a vertical line, the other end of the pushing rod is articulated with one end of a rear braking pedal, and a middle left part of the rear braking pedal is articulated with a support shaft located on the motorcycle frame; and one end of a return spring is connected with the upper side of the middle left part of the rear baking pedal while the other end of the return spring is connected with a hanging bolt of an engine. The invention saves the manufacture cost, and also effectively avoids the influences on braking effect and the situation of turning over because of accumulation error caused by too many force transferring components; because the installation position of the main hydraulic pump is changed, the interference of a disc brake main pump and a motorcycle body can be avoided effectively, and the assembly and the debugging are simple, convenient and fast, and can be finished within 3 minutes; in addition, the braking process can be directly regulated without dismounting a flat fork and other parts.
Description
Technical field
The present invention relates to the brake for motorcycle parts, be specifically related to disc brake hydraulic gear behind a kind of motor bike.
Background technology
The disc brake hydraulic gear is the force transmission mechanism that the moment of torsion that rear brake pedal in the braking procedure produces is delivered to drg behind the motor bike.The disc brake hydraulic gear comprises hydraulic pressure main pump, first push rod, lever, second push rod, rear brake pedal and pull back spring behind the existing motor bike; The hydraulic pressure main pump is located by connecting on the vehicle frame and with horizon by stay bearing plate and is inclined upwardly slightly, the fulcrum of lever and the front end of chain stay are hinged on the vehicle frame together, one end of first push rod is connected with the hydraulic pressure main pump, the other end is connected with an end of lever, the other end of lever is connected with an end of second push rod, and the other end of second push rod is connected with the end that the location dumpling is connected on the rear brake pedal on the vehicle frame.At glancing impact, the moment of torsion that rear brake pedal produces needs just can be delivered to the hydraulic pressure main pump through second push rod, lever and first push rod, because the power transmission line of first push rod and the line of centers of hydraulic pressure main pump be in-line not, the intermediate link of power transmission is more in addition, causes occurring the braking weakness and step on the situation of turning over taking place in braking procedure.In addition, also there is following defective: the one, high especially to the requirement of strength of stay bearing plate that the hydraulic pressure main pump is installed, because in brake process, rear brake pedal produces sizable moment of torsion, and the stay bearing plate that the hydraulic pressure main pump is installed is easy to distortion; The 2nd, the hydraulic pressure main pump is easily interfered with body of motor cycle, causes assembling that the hydraulic pressure main pump is extruded and occurrence positions changes, and rigging position changes the back and directly influences the normal result of use of hydraulic pressure main pump, and it is very difficult to assemble right body; The 3rd, assembling and burn in period need spend about 10 minutes, if need debugging brake stroke, also need pull down bottom fork assembly and just can regulate.Therefore, need carry out substantial improvement to the installation site and the structure of disc brake hydraulic gear behind the existing motor bike.
Summary of the invention
The purpose of this invention is to provide disc brake hydraulic pressure transfer mechanism behind a kind of motor bike, it is simple for structure, in braking procedure stay bearing plate be not easy to be out of shape, the position stability of hydraulic pressure main pump, can not only avoid back disc brake hydraulic pressure main pump and car body to interfere, and assemble and debug easy, quick.
Disc brake hydraulic pressure transfer mechanism behind a kind of motor bike of the present invention, comprise hydraulic pressure main pump, an end and hydraulic pressure main pump bonded assembly push rod, it is characterized in that: described hydraulic pressure main pump is located by connecting on the vehicle frame by a little stay bearing plate, and be tilted to the right slightly along vertical curve, one end dumpling of the other end of push rod and rear brake pedal connects, and the middle left part of rear brake pedal connects with the support shaft dumpling that is positioned on the vehicle frame; One end of one pull back spring is connected with the upside of the middle left part of rear brake pedal, the other end and engine suspension bolted connection, after its return spring plays in this structure and stepping on brake pedal, can allow to allow the rapid return of brake pedal behind operator's releasing of brake pedal.
Disc brake hydraulic pressure transfer mechanism behind described a kind of motor bike, the oil inlet of its described hydraulic pressure main pump 3 is connected with hydraulic oil pipe 2, oil outlet hydraulic-brake hose 1 connects.
The present invention compares with prior art and has the following advantages:
(1) two transoms between hydraulic pressure main pump and the rear brake pedal have been cancelled, not only saved manufacturing cost, and the push rod of hydraulic pressure main pump directly is connected with the rear brake pedal, thus avoided effectively that Force transmission parts is more cumulative errors to be occurred and influence braking effect and stepping on and turn over phenomenon and take place:
(2) owing to changed the installation site of hydraulic pressure main pump, not only actv. has been avoided the phenomenon that disc brake main pump and car body are interfered;
And make assembling and debug easyly, quick, only need within 3 minutes, can finish, and need not tear chain stay open and other parts just can directly be regulated the stroke that brakes.
Description of drawings
Fig. 1 is the scheme drawing of disc brake hydraulic gear behind the existing motor bike;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Referring to disc brake hydraulic pressure transfer mechanism behind a kind of motor bike shown in Figure 2, comprise an end and hydraulic pressure main pump 3 bonded assembly push rods 5, described hydraulic pressure main pump is located by connecting on the vehicle frame by a ramuscule fagging 14, and be tilted to the right slightly along vertical curve, one end dumpling of the other end of push rod 5 and rear brake pedal 10 connects, and the middle left part of rear brake pedal connects with support shaft 9 dumplings that are positioned on the vehicle frame; One end of one pull back spring 11 is connected with the upside of the middle left part of rear brake pedal 10, the other end and engine suspension bolted connection, after its return spring plays in this structure and stepping on brake pedal, can allow to allow the rapid return of brake pedal behind operator's releasing of brake pedal; The oil inlet of hydraulic pressure main pump 3 is connected with hydraulic oil pipe 2, oil outlet hydraulic-brake hose 1 connects.
Referring to Fig. 1, the present invention compares with disc brake hydraulic gear behind the existing motor bike, lever 6, second push rod 8 and 12 3 parts of pull back spring stay bearing plate have not only been reduced, reduced big stay bearing plate 4, made an appointment with manufacturing cost, and assembling and debugging the time does not need to pull down bottom fork assembly 13 and bottom fork axis 7 can be regulated, shortened the time of assembling and debugging greatly.
