Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
The structural representation of Fig. 1, the utility model embodiment;
Fig. 2, be the block diagram of the utility model embodiment;
Fig. 3, be the utility model motion conditions scheme drawing.
The specific embodiment
Referring to above-mentioned accompanying drawing as can be known: a kind of shaft drive speed change booster, it is characterized in that: it comprises housing 1 and secured in parallel power input shaft 2 and the power take-off shaft 3 in housing 1, power input shaft 2 upper spline bonded assembly speed change reinforcement driving gears 4 and often connect driving gear 5, at speed change reinforcement driving gear 4 with often connect shifting fork mechanism 10 between the driving gear 5, the automatic-reset spring 6 of the opposite side of the speed change reinforcement driving gear 4 on power input shaft 2; Power take-off shaft 3 upper spline bonded assembly speed change reinforcement driven gears 7 and often connect driven gear 8; The driven gear 8 that often connects that often connects on driving gear 5 and the power take-off shaft 3 on the power input shaft 2 meshes.
Above-mentioned power input shaft 2 and power take-off shaft 3 are in bearing 9 is fixedly attached to housing 1.
Above-mentioned shifting fork mechanism 10 is made up of shift fork 10a, declutch shift shaft 10b, automatic in-position spring 10c, joystick 10d, connecting rod 10e, wherein shift fork 10a places above-mentioned speed change reinforcement driving gear 4 and often connects 5 of driving gears, on the declutch shift shaft 10b that shift fork 10a and automatic in-position spring 10c sky are enclosed within, and be installed in the housing 1, joystick 10d is installed on outside the housing 1, and connecting rod 10e is connected joystick 10d with declutch shift shaft 10b.
Above-mentioned power input shaft 2 is the power take-off shaft of motor cycle engine; Above-mentioned power take-off shaft 3 is connected with the motor bike rear-axle differential through universal-joint 11.
In conjunction with Fig. 1, when the utility model was used for motor cycle engine shaft drive gear reversing device, above-mentioned power input shaft was the spline transmission output shaft of reverse gear again, and above-mentioned takeoff output beam warp universal-joint is connected with the motor bike rear-axle differential.
When power input shaft just changes, power by often connect driving gear pass to be engaged with often connect driven gear, often connecing driven gear drives and its spline bonded assembly power take-off shaft, power take-off shaft is passed to rear-axle differential to power transmission by the affixed universal-joint of spline again, thereby realizes the motor bike advancement function.
When power input shaft reverses, power by often connect driving gear pass to be engaged with often connect driven gear, often connecing driven gear drives and its spline bonded assembly power take-off shaft, power take-off shaft is passed to rear-axle differential to power transmission by the affixed universal-joint of spline again, thereby realizes the motor bike car-backing function.
When often connecing driving gear and often connecing driven gear and be meshed, travel for common; Often connect driving gear and often connect driven gear and separate when shifting fork mechanism makes, when making the speed change reinforcement driven gear engagement of speed change reinforcement driving gear and large speed ratio, large speed ratio speed change reinforcement driven gear with transmission of power on the power take-off shaft, reduced the speed of power take-off shaft, increase the moment of torsion of power take-off shaft, thereby realized reinforcement.
In conjunction with Fig. 2 and Fig. 3 shifting fork mechanism is described: when the needs reinforcement, depressing joystick makes connecting rod drive the motion of shift fork axial arrow H direction with the E point that is connected of declutch shift shaft, the then empty automatic in-position spring that is enclosed within on the declutch shift shaft is moved to the H direction by the motion promotion shift fork of declutch shift shaft, the shift fork drive often connects the driving gear disengaging and often connects driven gear, promotes the engagement of speed change reinforcement driving gear and speed change reinforcement driven gear simultaneously.The point of connection F point of connecting rod in figure and joystick was pressed the attachment point G point horizon following time of E point to joystick and housing, and whole shifting fork mechanism will automatically lock, speed change reinforcement driving gear this moment automatic in-position under the effect of automatic in-position spring; And when not needing reinforcement,, often connect driving gear and promptly can under the effect of automatic-reset spring, automatically reset the joystick reverse operating.
