Abstract
The invention relates to a motorcycle transmission. The motorcycle transmission consists of an input shaft, an intermediate shaft, an output shaft, a gear pair and an operating mechanism. The operation mechanism of the transmission is arranged outside a gearbox casing. The other end of a variable speed drum is provided with a shift locking mechanism. Compared with the conventional motorcycle transmission, the motorcycle transmission of the invention simplifies the internal structure and reduces the production cost.
Description
Technical field
The present invention relates to a kind of speed changer, particularly relate to a kind of motorcycle gear box.
Background technique
At present, the Effector great majority of known motorcycle gear box all are the variable-speed shaft rotations that drives speed changer inside by gear shift pedal or shift, again by extension spring, the motion of gear arm etc. realizes gearshift, but this shift operating device number of parts is more, make mission case internal structure complexity, corresponding cost also increases much, is unfavorable for that the marketization competes.
Summary of the invention
In order to overcome present speed changer structure complexity, the higher deficiency of cost, the invention provides a kind of speed changer, this speed changer adopts a kind of simple external shift control mode, makes whole speed changer internal structure simplify, and cost reduces.
The technical solution adopted for the present invention to solve the technical problems is: this motorcycle gear box, thereby the gear pair and axial the moving of actuation gear that comprise casing, input shaft, jack shaft, output shaft and adorn are respectively thereon realized the speed-changing drum and the shift fork of speed change, its key is: the operating mechanism of this speed changer is arranged in the gearbox casing outside, and be connected with speed-changing drum by rotating disk, be provided with the gear lockable mechanism at the speed-changing drum the other end.
Described operating mechanism comprises operating handle, rotating disk and drag-line, and operating handle is connected with rotating disk A, and rotating disk A, rotating disk B are connected with drag-line B by drag-line A, and speed-changing drum is rotated by two drag-line pulling dial rotation.
Described gear lockable mechanism comprises dials plate, positioning plate combination and Returnning spring; Dial the other end that plate is contained in speed-changing drum, and rotate with speed-changing drum; Roller in the positioning plate combination moves along the external frame of dialling plate, and under the effect of Returnning spring, compress the external frame of dialling plate all the time, when the roller in the positioning plate combination is pressed in group plate groove, just change to a certain gear, continue the pulling shift, as changing to another gear again with upper type.
According to the above-mentioned motorcycle gear box that assembles, its working procedure such as following:
The power of motor passes to transmission input shaft by medium tache, passes to jack shaft by driving gear on the input shaft again, is delivered to output shaft through countershaft-gear again.Be installed with on the inner input shaft of speed changer with input shaft by spline package together can be along axially movable gear of input shaft and the empty gear that is enclosed within on the input shaft, also be installed with on the jack shaft with jack shaft by spline package together can be along axially movable gear of jack shaft and the empty gear that is enclosed within on the jack shaft, gear on the output shaft and the fixed gear on the jack shaft often mesh; One end of speed-changing drum is installed with round turntable, rotating disk spurs by drag-line, during neutral gear, movably free gear engagement on gear and the jack shaft on the input shaft, removable gear engagement on free gear and the jack shaft on the input shaft, removable gear rotates with input shaft on the input shaft at this moment, but jack shaft does not still rotate, the unpowered output of whole speed changer, in the time will hanging up a certain gear, the pulling shift makes cable pull, drag-line just hauls rotating disk and speed-changing drum rotation, thereby the shift fork that the upper end pin is inserted in the speed-changing drum guiding groove moves axially a distance along declutch shift shaft, the shift fork lower end is connected with removable gear, thereby make removable gear vertically the free gear on mobile phase same distance and the same axle link together by ratchet, with this locking position, just realize gear-change operation at the other end gear lockable mechanism of speed-changing drum.
The invention has the beneficial effects as follows, simplify the speed changer internal structure, reduce manufacture cost.
