Abstract
The utility model discloses a stepless speed changing mechanism for the engines on motorcycles, comprising a crank shaft, a main shaft, a primary clutch component, a main clutch component, a unidirectional overrunning clutch component, a drive gear, a driven gear and a motor gear; wherein, the crank shaft is sleeve jointed with the primary clutch component and comprises a flail block, a friction disk and a center sleeve, the main clutch assembly, the unidirectional overrunning clutch assembly, the middle gear, the drive gear of the primary clutch assembly, the drive gear of the main clutch component and other members; the main shaft is sleeve jointed with the driven gear of the primary clutch component, the driven gear of the main clutch component and other members. The utility model is characterized in that when the speed is less than N2, the torque is transmitted through the rotation of the primary clutch assembly, the drive gear of the primary clutch component and the driven gear of the primary clutch component and others; when the speed is more than N2, the torque is transmitted through the rotation of the main clutch component, the drive gear of the main clutch component and the driven gear of the main clutch component and others. The utility model has the advantages of simple structure, low cost and capable of stepless speed changing.
Description
The utility model relates to a kind of gear of motorcycle engine speed change gear, particularly a kind of stepless variable engine.
In the prior art, motorcycle engine mostly is to realize the change of speed, its structure more complicated, cost height, complicated operation by the loaded down with trivial details speed change gear of a cover.A kind of motorcycle gasoline engine with automatic gear-shifting realization mechanism is arranged, and the patent No. is: ZL99241192.0.This kind automatic gear-shifting mechanism can realize automatic speed regulation, and structure is also fairly simple, but its main clutch is installed on the main shaft, because spindle speed is slower, main clutch bears bigger moment of torsion, and its life-span is subjected to very big influence, so the structure of the gear shift mechanism of this kind motorcycle gasoline engine needs to improve.
The utility model has adopted a kind of than rational structure: at first cancelled speed change gear and pin starting drive, made relatively simple for structure in order to overcome above deficiency; Secondly realize from low speed to high speed by two cover centrifugal clutch assemblies and a cover mono-directional overrun clutch assembly or automatic transition, to realize infinite variable speed purpose from high speed to low speed; Once more, two cover centrifugal clutch assemblies and a cover mono-directional overrun clutch assembly all are installed on the bent axle, make each clutch bear less moment of torsion, help improving its service behaviour and life-saving.The automatic clutch, simple to operate but this scheme can reduce cost is also with the operating function of foot plate bicycle motor.
Be described further below in conjunction with accompanying drawing:
In the time of in certain rotational speed N 1---N2 (N1 is less than N2) scope, intermediate gear (7) on the bent axle (11) drives mono-directional overrun clutch assembly (6) and rotates, mono-directional overrun clutch assembly (6) drives primary clutch assembly (2) and rotates, the piece (5) that gets rid of in the primary clutch assembly (2) compresses friction plate (4) under action of centrifugal force, friction plate (4) drives central sleeve (3) and rotates, central sleeve (3) drives primary clutch driving gear (1) and rotates, primary clutch driving gear (1) drives primary clutch driven gear (12) and rotates, and this gear (12) is again by spindle part (13) transmitting torque.In this speed range, the fast assembly of main clutch hoof (10) can not compress main clutch outer cover (9) because of centrifugal force is too little, thereby can not transmitting torque.
When bent axle (11) when rotating speed is higher than N2, the fast assembly of main clutch hoof (10) compresses main clutch outer cover (9) under centrifugal action, main clutch outer cover (9) drives main clutch driving gear (8) and rotates, drive main clutch driven gear (14) again and rotate, this gear (14) is again by spindle part (13) transmitting torque.In this speed range, because of main clutch velocity ratio i1 less than primary clutch velocity ratio i2, then make spindle speed n1 greater than n2, thereby make mono-directional overrun clutch assembly (6) be in the strong attitude of skidding, primary clutch assembly (2) is transmitting torque no longer.
Claims (2)
1. the stepless speed changing mechanism of a motorcycle engine, by bent axle, main shaft, the primary clutch assembly, the main clutch assembly, mono-directional overrun clutch assembly, driving gear, driven gear and intermediate gear are formed, and it is characterized in that: be set with intermediate gear (7), mono-directional overrun clutch assembly (6), primary clutch assembly (2), the fast assembly of main clutch hoof (10), primary clutch driving gear (1), main clutch driving gear (8) on the bent axle (11); Be set with primary clutch driven gear (12), main clutch driven gear (14) on the spindle part (13); Intermediate gear (7) drives mono-directional overrun clutch assembly (6) and rotates, mono-directional overrun clutch assembly (6) drives primary clutch assembly (2) and rotates, central sleeve (3) drives primary clutch driving gear (1) and rotates, and primary clutch driving gear (1) drives primary clutch driven gear (12) and rotates; The fast assembly of main clutch hoof (10) drives main clutch driving gear (8) and rotates, and main clutch driving gear (8) drives main clutch driven gear (14) and rotates.
2. stepless speed changing mechanism according to claim 1 is characterized in that: described primary clutch assembly (2) is formed by getting rid of piece (5), friction plate (4) and central sleeve (3).
