Abstract
Disclosed is a gear shifting mechanism of a motorcycle which consists of a foot pedal having a sleeve and an engine gearshift shaft. A section of lever arm is arranged on the foot pedal, the lever arm of the foot pedal is connected with one end of a connection rod by one joint bearing, the other end of the connection rod is connected with a spindle having a splined hole through the other joint bearing, the splined hole of said spindle covers tightly on said engine gearshift shaft; the sleeve of said foot pedal covers on a frame shaft of the motorcycle frame with clearance fits. The utility model can simplifies the design of the girder-bent frame gradually; thus promoting the tendency of simplification on the design of said girder-bent frame; and furthermore devising various styles of fine figured motorcycles according to the market demand isolating from limit descriptions in the background technique. Therefore, different styles and quite fine shapes of motorcycles can be schemed out.
Description
One, technical field
The utility model relates to the gear shift mechanism of motor bike, especially the gear shift mechanism of camber beam vehicle frame motor bike.
Two, background technology
At present, adopting the gear shift mechanism of operated by foot in camber beam vehicle frame motor bike, is directly the axle sleeve on the footrest frame of this gear shift mechanism tightly to be enclosed within on the shift axle of driving engine.This connection mode is fit closely for the motor bike that adopts general vehicle frame.But for the motor bike that adopts the camber beam vehicle frame, with regard to the bad cooresponding problem in the interaxle mutual alignment of shift of axle sleeve that its footrest frame occurred and driving engine.So, not only make the structure of camber beam vehicle frame become very complicated, but also hindered the development prospect (adopting the purpose of camber beam vehicle frame) that adopts the camber beam vehicle frame for designing and manufacturing various different style, profile motor bike very attractive in appearance again.
Three, summary of the invention
The purpose of this utility model is adapted at the gear shift mechanism that uses on the camber beam vehicle frame motor bike for overcoming above-mentioned shortcoming, designing.
Realize the gear shift mechanism of a kind of camber beam vehicle frame motor bike of described purpose, it includes the footrest frame of tape spool cover and driving engine shift axle etc.One section rocker arm is arranged on the described footrest frame, rocker arm by an oscillating bearing, this footrest frame connects with an end of a pipe link, the other end by another oscillating bearing, described pipe link connects with a fork that has splined hole again, and the splined hole of described fork tightly is enclosed within on the described driving engine shift axle.The axle sleeve of described footrest frame is enclosed within on the support shaft on the frame of motorcycle with being free-running fit, and obviously, the described axle sleeve that is enclosed within on its support shaft is blocked by an anti-avulsion mechanism, so that the unlikely slippage of this footrest frame.
The preceence that the technical program is taken to is as follows:
Be not difficult to find out in the scheme that the utility model has adopted one group of simple four-bar mechanism to solve the axle sleeve of aforesaid footrest frame and the interaxle position of the shift correspondence problem of driving engine.But suitably change the length of described pipe link, the also length of described rocker arm of appropriate change and/or fork in case of necessity, just can be the motion of footrest frame and transmission of power shift axle to the driving engine of any position.So, also just can make the design of described camber beam vehicle frame be tending towards oversimplifying; More can be according to the needs in market, restrictedly do not design motor bike various different style, that profile is very attractive in appearance again.
Four, description of drawings
Fig. 1---the utility model front view
The birds-eye view of Fig. 2---Fig. 1
Five, the specific embodiment
A kind of gear shift mechanism of motor bike, it includes the footrest frame 10 of tape spool cover 11 and driving engine shift axle 40 etc.One section rocker arm 12 is arranged on the described footrest frame 10, rocker arm 12 by a hinge 13, this footrest frame 10 connects with an end of a pipe link 20, the other end by another oscillating bearing 33, described pipe link 20 connects with a fork 30 that has splined hole again, and the splined hole of described fork 30 tightly is enclosed within on the described driving engine shift axle 40.This hinge 13, oscillating bearing 33 directly are made in the termination of described rocker arm 12 and fork 30 respectively; Respectively there is an adjusting lock nut 21 at the two ends of described pipe link 20, to be used to finely tune the optimum length with fixed connecting rod 20.The axle sleeve 11 of described footrest frame 10 is enclosed within on the support shaft 50 on the frame of motorcycle with being free-running fit, has one to prevent these footrest frame 10 slippages and block the baffle plate 60 of its axle sleeve 11 in the outer end of support shaft 50.This support shaft 50 can be the axle that for this reason is fixed on specially on its vehicle frame, also can be to utilize the existing foot-rest bracket axle of vehicle frame itself, and present embodiment is to adopt the latter.
