Description
One, technical field
The utility model relates to a kind of motorcycle engine speed change gear, particularly a kind of motorcycle engine self-locking gear reversing device.
Two, background technique
Motorcycle mainly is that three-wheel or four-wheeled motorcycle engine are provided with gear reversing device, and gear reversing device has improved the operating characteristics of motorcycle.But, if, when motorcycle engine is equipped with gear reversing device, the reverse gear locking safety device is not set, so, just might serious equipment, personal safety accident take place because of misoperation.Such as, when motorcycle moves ahead, change because of misoperation and to cause reverse gear, motor is violently shaken and damages.In order to prevent this class security incident, in the prior art, generally adopt a kind of manually operated type reverse gear locking safety device.Its locking framework is realized by manual drag-line and resilient member.When motorcycle moved ahead, under the effect of resilient member, reverse gear was locked by device.When changing the reverse gear position, by manual drag-line (or other leverages) the reverse gear limit stoper is opened earlier, just can change to reverse gear position then, this device can be avoided the generation of security incident effectively.But, this manual lock fixed pattern gear reversing device part that also comes with some shortcomings, subject matter is mechanism's complexity, operation inconvenience, reliability is not so good, in addition, manual drag-line via hole must be set on the crankcase, manually the sealing of drag-line via hole is relatively more difficult, thereby, can cause the engine crankcase inner engine oil to leak.
Three, model utility content
In order to overcome the deficiencies in the prior art, this practical purpose provides the built-in self-locking gear reversing device of a kind of motorcycle engine, and this gear reversing device is simple in structure, easy to operate, safe and reliable, and can overcome the problem that manual drag-line via hole machine oil leaks.
A kind of motorcycle engine self-locking gear reversing device, comprise main shaft 1, countershaft 2, speed-changing drum 3, engagement cover 4, reverse gear driving wheel 5, reverse gear driven 6, reverse idler gear 7, reverse gear driving wheel 5 is sleeved on the main shaft 1, engagement cover 4 also is sleeved on the main shaft 1 by spline, can endwisely slip, reverse gear driven 6 is fixedly on the countershaft 2, reverse idler gear 7 is installed on the casing by idler shaft, it is characterized in that a kind of motorcycle engine self-locking gear reversing device also comprises butterfly spring 8, spacing ratchet 9, axial direction positioning device 10, butterfly spring 8, spacing ratchet 9 is sleeved on the countershaft 2, and by axial direction positioning device 10 both is pressed against on the end face of the shaft shoulder or gear.Speed-changing drum 3 cylindricals are provided with the cam path and the restraining groove 11 that reverses gear, and when engagement cover 4 slides to the interior colored groove of reverse gear driving wheel 5, reverse gear driving wheel 5 is fixedly connected with main shaft 1, at this moment reverse gear driving wheel 5 will drive countershafts 2 counterrotatings by reverse idler gear 7.Otherwise, when engagement cover 4 slides to opposite side, reverse gear driving wheel 5 just can only be in main shaft 1 idle running and can not transferring power, when motorcycle moves ahead, because the elastic force effect of butterfly spring 8, can produce certain friction torque, spacing ratchet 9 is rotated with countershaft 2, after spacing ratchet 9 is run into the cylindrical of speed-changing drum 3, spacing ratchet 9 no longer rotates with countershaft 2, but is pressed on the periphery of speed-changing drum 3, at this moment, if when making other gear speed change, spacing ratchet 9 is made slide relative with speed-changing drum 3, and when speed-changing drum 3 forwarded neutral position to, spacing ratchet 9 inserted in the restraining groove 11 at speed-changing drum 1 cylindrical place under the effect of frictional force automatically, thereby the restriction speed-changing drum continues to reach the purpose of auto lock towards the rotation of reverse gear position direction.
The utility model compared with prior art has following characteristics: 1, when motorcycle moves ahead, automatically lock reverse gear, and need not manual operation; 2, saved manual drag-line, simple in structure; 3, owing to there is not a drag-line via hole, can the Yin Lasuo via seal not bad, and the engine motor oil that the causes problem that leaks.
