Abstract
The utility model discloses an engine reverse gear apparatus, a spindle and a countershaft are respectively provided with a start gear, a first gearshift gear, a second gearshift gear, a third gearshift gear, a fourth gearshift gear and a reverse gear. The utility model is characterized in that: the reverse intermediate gear (7) with a pressure plate (6) is arranged between a spindle reverse gear (8) and a countershaft reverse gear (9), so the reverse intermediate gear (7) is meshed with the spindle reverse gear (8) and the countershaft reverse gear (9). The utility model arranges a reversing drive gear inside an engine crankshaft box, and a motorcycle can be freely reversed through the reverse gears on the spindle and the countershaft; a set of speed shifting and steering mechanism which is arranged outside the engine primarily is canceled, so the structure is simple, the cost is low, and the countershaft spline can not be damaged, safe and convenient use is provided.
Description
(1). technical field
The utility model belongs to engine art, particularly a kind of reverse gear apparatus that is used for motorcycle engine.
(2). background technique
At present, discharge capacity normally increases a cover speed change and a steering equipment, its complex structure, cost height in the motor outside at the reverse gear mechanism of the motorcycle engine of 125ml.Because this mechanism is installed in the motor outside, and normally adopts driven off by shaft mode.When motorcycle need reverse gear, the reverse gear mechanism that is installed in the motor outside was asynchronous with the countershaft running, causes the motor spline to cut flat, and reduces the working life of motor.
(3). summary of the invention
The purpose of this utility model provides a kind of motor reverse gear apparatus.It is simple in structure, reverses gear conveniently, can prolong the working life of motor.
For reaching above-mentioned purpose, the utility model is equipped with main shaft starter receiver, main shaft first gear, main shaft second gear, main shaft three retaining gears, main shaft four retaining gear and main shaft reverse gears on main shaft, countershaft reverse gear, countershaft four retaining gears, countershaft three retaining gears, countershaft second gear, countershaft first gear and countershaft starter receiver are installed on countershaft, it is characterized in that the third wheel that reverses gear that has pressing plate is installed between main shaft reverse gear and countershaft reverse gear, make reverse gear third wheel and main shaft reverse gear and the engagement of countershaft reverse gear.
Reversed gear and bearing was installed in the tooth.
The utility model can make motorcycle reverse gear freely because a commutation driving gear directly is installed in engine crankcase by the reverse gear on the major-minor axle.The utility model increases by a cover speed change and a steering equipment owing to cancelled the former motor outside that is installed in, and therefore simple in structure, cost is low, and can not damage the countershaft spline, and is safe in utilization, convenient.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is a structure diagram of the present utility model.
(5). embodiment
Referring to Fig. 1.Main shaft starter receiver 1, main shaft first gear 2, main shaft second gear 3, main shaft three retaining gears 4, main shaft four retaining gear 5 and main shaft reverse gears 8 are installed on main shaft 16, countershaft reverse gear 9, countershaft four retaining gears 10, countershaft three retaining gears 11, countershaft second gear 12, countershaft first gear 13 and countershaft starter receiver 14 are installed on countershaft 15.The third wheel 7 that reverses gear that has pressing plate 6 is installed between main shaft reverse gear 8 and countershaft reverse gear 9, is made reverse gear third wheel 7 and main shaft reverse gear 8 and 9 engagements of countershaft reverse gear.Reversing gear is equipped with bearing 15 in the tooth 7, fixes with collar.To cross wheel shaft 17 and pass bearing 18 center holes, and be installed in crossing in the axle hole of left crankcase, pressing plate 6 is fixed on the left crankcase, and the two ends of main shaft 16 and countershaft 15 are fixed on the crankcase of the left and right sides.
Main shaft starter receiver 1, main shaft second gear 3, main shaft four retaining gears 5, the third wheel 7 that reverses gear, countershaft reverse gear 9, countershaft three retaining gears 11, countershaft first gear 13 and countershaft starter receiver 14 do not rotate with axle in this device; Main shaft first gear 2, main shaft three retaining gears 4, main shaft reverse gear 8, countershaft four retaining gears 10 and countershaft second gear 12 rotate with the rotation of axle.
When the motorcycle of operation need reverse gear, during engine operation, main shaft 16 starter receivers 1 and countershaft starter receiver 14, main shaft first gear 2 and countershaft first gear 13, main shaft second gear 3 and 12 engagements of countershaft second gear, main shaft three retaining gears 4 and 11 engagements of countershaft three retaining gears.Driving shaft drives 8 rotations of main shaft reverse gear simultaneously, main shaft reverse gear 8 drives the tooth 7 that reversed gear and rotates, the tooth 7 that reversed gear drives countershaft reverse gear 9 and rotates, and countershaft reverse gear 9 drives countershaft four retaining gears 10 and rotates, and countershaft four retaining gears 10 drive countershaft 15 backward rotation.Countershaft 15 reverse outputting powers reverse gear motorcycle.After motorcycle reverses gear, make major and minor axle associated gear enter the selection gear engaged by its gearshift.
Claims (2)
