Abstract
A mechanism that can lock the motorcycle engine reverse gear. Its feature is that the mechanism is made up of lock crust, oil sealing ring, lock-pin, return spring, bulkhead and handle. The return spring and the oil sealing ring are muff coupled in the lock-pin and are located in the lock crust. One end of the lock-pin equipped in the lock crust protrudes out of the lock crust and the other end protrudes through the bulkhead and tightly connects to the inside of the handle. The under-part of the lock crust is threaded coupled with the left crankcase body of the engine. The end that protruding out of the lock crust inserts into the shifting fork annular of the five steps gear on the auxiliary shaft of the engine. The advantages are simple structure, expediently and neatly to be operate.
Description
Technical field
The present invention relates to a kind of motorcycle engine, especially the Reverse of Motorcycle Engine lockable mechanism.
Background technique
Gear reversing device is set on the motorcycle engine, helps improving the operation and the Security of motorcycle.At present, the motorcycle reverse gear is to realize by the gear shift transmission that motor internal speed-changing drum is controlled on main shaft, the countershaft.And speed-changing drum is a kind of cylindrical body that has groove on circumference, its groove has smooth section, the deformation of unevenness section is also arranged, groove that is arranged in speed-changing drum of in-engine shift fork, in the fork slot of an insertion driving gear, when speed-changing drum is rotated, the shift transmission of shift fork sliding zone moving gear in its groove.Existing motorcycle all is the rotation of controlling speed-changing drum by driver's foot pedal, and driver's pin is stepped on once, and the gear increasing or decreasing once.Though operation easily forms driver's misoperation easily like this, usually is to step on two times more, does not just remember clearly and oneself stepped on how many times also do not known to be in what gear actually.Because the gear of Reverse of Motorcycle Engine is in proper order: reverse gear → neutral gear → 1 grade → 2 grades → grade 3 → 4 grades, 4 grades then → 3 grades → 2 grades → 1 grade → neutral gear → reverse gear; Therefore, motorcycle is easy to occur driver's misoperation and makes motor slip into reverse gear from neutral gear in the process of moving, and motor oppositely reverses suddenly, causes engine damage or personal safety accident.If can not rationally control reverse gear opportunity, just have hidden danger.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can prevent the driver when driving, because of misoperation slips into the Reverse of Motorcycle Engine lockable mechanism that reverse gear causes security incident with motor.
Concrete scheme of the present invention is: comprise motor left crankcase, engine countershaft, reverse gear, five grades of gears and be threaded in reverse gear locking device on the left crankcase, its invention main points are: reverse gear locking device is made up of lock housing, oil seal washer, lock pin, return spring, plug, handle, wherein return spring and oil seal washer are sleeved on the lock pin, and be positioned at lock housing, one of the lock pin that is contained in the lock housing stretches out outside the lock housing, and the other end is passed plug and is fastenedly connected in handle; Stretch out the outer lock pin end of lock housing and stretch in the left crankcase, be inserted in the shifting fork annular of five grades of gears.
The present invention utilizes the shifting fork annular of five grades of gears on the former motor, and the lock pin by lockable mechanism inserts to be controlled five grades of gears in the shifting fork annular of five grades of gears and move axially, and drives the reverse gear rotation thereby retrain five grades of gears with the engagement of reverse gear end face; Lock pin inserts the normal rotation that does not influence five grades of gears in the shifting fork annular simultaneously, and this lock pin only moves around annular groove in shifting fork annular.When the needs reverse gear, lock pin is withdrawed from the shifting fork annular of five grades of gears, five grades of gears slide to reverse gear under original shift fork effect smoothly in motor, make motor finish reverse gear work.
The invention has the beneficial effects as follows: can control motor reverse gear opportunity, effectively prevent the driver when driving, cause motor to damage or personal injury accident because misoperation slips into reverse gear with motor.It is simple in structure, and is easy to operate, flexible, does not influence the cruising of motorcycle.
Description of drawings
Fig. 1 is a lockup state structural representation of the present invention;
Fig. 2 is an open mode structural representation of the present invention;
Fig. 3 is the structural drawing of reverse gear locking device 5 among Fig. 1.
Embodiment
Please see Figure 1, Fig. 2, Fig. 3, the present invention is by starting left crankcase 1, engine countershaft 2, reverse gear 3, five grades of gears 4, reverse gear locking device 5 is formed, wherein the motor left crankcase 1, countershaft 2 and be installed in reverse gear 3 on the countershaft 2, five grades of gears 4 are identical with the prior art structure, the lockable mechanism 5 that different are mounted on the engine crankshaft casing 1 is by lock housing 8, oil seal washer 9, lock pin 10, return spring 11, plug 7, handle 6 is formed, wherein return spring 11 and oil seal washer 9 are sleeved on the lock pin 10, and be positioned at lock housing 8,10 1 of lock pins that are contained in 8 li of lock housings stretch out outside the lock housing 8, and the other end is passed plug 7 and is fastenedly connected in handle 6 and (can adopts and be threaded); Stretch out lock housing 8 outer lock pin 10 ends and stretch in the left crankcase 1, insert in the shifting fork annular of five grades of gears 4.
In Fig. 1, Fig. 2, also have other transmission gear shift gear, they are sleeved on the countershaft 2, are positioned at a side of five grades of gears 4, and the opposite side of five grades of gears 4 is reverse gears 3.The rotation of reverse gear 3 is could realize that five grades of gears 4 will slide to reverse gear 3 after being engaged with by five grades of gears 4, needs to finish by being inserted in five grades of stirring of shift fork in gear 4 shifting fork annular, and this shift fork is controlled by speed-changing drum.Shifting fork annular on described speed-changing drum, reverse gear, five grades of gears, other driving gear, the five grades of gears 4 and the shift fork in the motor are prior art, its structure and connecting relation and
Prior art is identical.
Can further see from Fig. 3: described lock housing 8 is that an end is the straight-through tube of bolt arrangement, and this bolt part is threaded with motor left crankcase 1.Described plug 7 fastening lock housing 8 upper ends (can adopt to press-fit, make its interference fit) that are installed in, the internal diameter of this plug 7 are less than the internal diameter of lock housing 8, and handle 6 is placed in plug 7 tops.Described lock pin 10 is provided with two steps, and wherein a step is near the outlet of lock housing 8 lower ends, and the bottom that return spring 11, two steps are positioned at lock pin 10 is installed in another step top; Suit oil seal washer 9 between two steps helps oil seal washer and moves up and down with lock pin 10, has played the oil sealing effect.The external diameter of described step and return spring 11 is greater than the internal diameter of plug 7, and plug 7 just has position-limiting action like this, return spring 11 lock pin top bar and plug 7 between.
The present invention is work like this: under normal conditions, lock pin 10 is stretched in the engine housing 1, insert the shifting fork annular interior (as shown in Figure 1) of five grades of gears 4, prevent that driver's misoperation from slipping into reverse gear 3 with five grades of gears 4 to moving to left, the unexpected reverse rotation of motor is caused the accident.When motorcycle needed reverse gear to travel, the driver must upwards mention handle 6, and lock pin 10 and five grades of gears 4 are broken away from, and five grades of gears 4 on the countershaft can slip in the reverse gear 3 smoothly like this, make motor finish reverse gear operation (as shown in Figure 2).
