Abstract
The invention discloses a motorcycle gear shifting transmission device, which comprises a left crankcase cover, a left crankcase body, a right crankcase body, a gear shifting shaft and a gear shifting shaft component, wherein the left crankcase cover is arranged on the left crankcase cover; wherein: a transmission cover is arranged at the extending end of the shift shaft and is detachably connected to the left crankcase body; the supporting points of the shift shaft are arranged on the transmission cover and the left crankcase body, and the shift shaft is rotatably arranged and connected on the transmission cover and the left crankcase body. According to the motorcycle gear shifting transmission device, the transmission cover is arranged at the extending end of the gear shifting shaft, when the gear shifting transmission device is checked and maintained, only the transmission cover needs to be detached, and the right crankcase cover does not need to be detached, so that the number of detached parts is greatly reduced; because the right crankcase cover does not need to be detached, the main sealing surface of the engine is not affected, the sealing is tight, and adverse phenomena such as leakage and the like are basically avoided; the length of the shift shaft is greatly shortened, the processing is convenient and easy, and the manufacturing cost of the shift shaft is reduced.
Description
Technical field
The present invention relates to the power-transmitting unit of motorcycle, especially motorcycle shift transmission device.
Background technique
The effect of the speed changer in the motor-cycle power drive mechanism is speed and the tractive force that changes in the motorcycle driving, to adapt to the needs that travel under the different road conditions; Speed changer mainly is made of the shift transmission device that gear and operating mechanism are formed.Shift transmission device of the prior art as shown in Figure 1, shift transmission device is to be assembled in the space that left crankcase 4, right crankcase 5 and right crankcase cover 6 constituted, and installs with hermetic form; If when barrier or maintenance etc. need be carried out inspection and maintenance to shift transmission device for some reason, just must take right crankcase cover 6 apart, just can touch shift transmission device.But for motor, right crankcase cover 6 often is equipped with oil filter, water pump, pin and starts component such as axle, and is pretty troublesome during dismounting, waste time and energy; If to more than 6 dismounting of right crankcase cover, be easy to cause the poorly sealed reality of motor sealing surface, produce unfavorable phenomenons such as engine oil leakage; Simultaneously, the axle 1 of shift shaft parts is very long, because the machining accuracy of axial workpiece all has very high requirement usually, so the processing of axle 1 needs more man-hour, and reject rate is higher; The strong point of axle 1 is separately positioned on left crankcase 4 and the right crankcase 5, and distance is far away between two strong points, makes the reliability of shift control and flexibility be difficult to guarantee.So the shift transmission device of prior art can not adapt to the needs in market.
Background technique
The present invention is directed to the above-mentioned deficiency of prior art shift transmission device, a kind of simple in structure, easy to maintenance, shift control of dismounting motorcycle shift transmission device flexibly is provided.
Technological scheme of the present invention: motorcycle shift transmission device comprises left crankcase lid, left crankcase, right crankcase, shift shaft and shift shaft parts; It is characterized in that: the external part at shift shaft is provided with gear shift cover, and gear shift cover is detachable to be connected on the left crankcase; The strong point of shift shaft is set on gear shift cover and left crankcase, shift shaft is installed turnably, is connected on gear shift cover and the left crankcase.
Further feature is: in the space of shift shaft component-assembled between gear shift cover, left crankcase.
Motorcycle shift transmission device of the present invention with respect to prior art, has following characteristics:
1, the external part at shift shaft is provided with gear shift cover, when barrier or maintenance etc. need be carried out inspection and maintenance to shift transmission device for some reason, only gear shift cover need be disassembled, and right crankcase cover need not be disassembled, and has significantly reduced the amount of parts of dismounting.
2, owing to do not need right crankcase cover is disassembled, the primary sealing area of motor is had no effect, seal tightly, can not produce unfavorable phenomenons such as seepage substantially.
3, the length of shift shaft shortens greatly, and is easy to process, easy, reduces the manufacture cost of shift shaft.
4, shift control flexibly, conveniently, reliably.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is the shift transmission device structure diagram of prior art;
Fig. 2 is the shifter assemblies structural drawing of the shift transmission device of prior art;
Fig. 3 is a shift transmission device structure diagram of the present invention.
Embodiment
In Fig. 1,2, the 1-shift shaft, 2-left crankcase lid, 3-speed-changing drum assembly, the 4-left crankcase, the 5-right crankcase, the 6-right crankcase cover, 7-star is dialled plate, the combination of 8-check plate, 9-shift fork external member, 10-shifter assemblies;
The shift transmission device of prior art, the assembly of its gear shift transmission system is dialled combination 8 of plate 7, check plate and shifter assemblies 10 etc. as shift shaft 1, star, all is assembled in the space that left crankcase 4, right crankcase 5 and right crankcase cover 6 constituted.Its gear shift principle is: when external force is rotated shift shaft 1, shift shaft 1 is just stirred star and is dialled plate 7, thereby drive with star and dial speed-changing drum assembly 3 rotations that plate 7 is connected, make and move in the gear molded lines groove of shift fork external member 9 on speed-changing drum assembly 3, dial under the acting in conjunction of plate 7 and check plate combination 8 fixation star and realize the gear shift purpose at the gear of needs.As prior art, be not further described at this.
In Fig. 3,15-shift shaft, 16-shift shaft parts, 17-gear shift cover;
Motorcycle shift transmission device of the present invention comprises shift shaft 15, is arranged on the shift shaft parts 16 on the shift shaft 15; Its improvements are: the external part at shift shaft 15 is provided with gear shift cover 17, gear shift cover 17 detachable being connected on the left crankcase lid 2; The strong point of shift shaft 15 is set on gear shift cover 17 and left crankcase 4, shift shaft 15 is installed turnably, is connected on gear shift cover 17 and the left crankcase 4.When needing dismounting, only need gear shift cover 17 is opened, pulled down and get final product.
As we know from the figure, shift shaft parts 16 of the present invention are assembled in the space between gear shift cover 17, the left crankcase 4, shift shaft parts 16 are constant substantially with the Placement of shift shaft 15 and speed-changing drum assembly 3, and action principle is identical, and just its space bit is equipped with a bit and changes.Those skilled in the art does not need to spend performing creative labour and just shift shaft parts 16 and shift shaft 15 and speed-changing drum assembly 3 can be interconnected according to the disclosed content of presents.
