Abstract
The utility model relates to a sliding shaft keylock gear transmission, which comprises a main speed reduction mechanism, transmission gears, a power output shaft, change-speed gears, a speed-governing ring, a gear-shifting device and the like. A clutch inputs power into the power input shaft so as to realize the primary speed reduction. All the transmission gears on a transmission gear shaft are meshed with the corresponding change-speed gears. When a keylock is in a locking state, the change-speed gears freely rotate relative to the power output shaft and present an idle state. During the speed governing process, the sliding shaft of the keylock is pulled through a gear shifting fork and the change-speed gear used for locking some gear is selected by changing the position of the keylock so as to realize the gear adjustment. During the gear reversing process, the sliding shaft of the keylock is pulled by a speed-governing ring shifting rod so as to ensure that the keylock is popped from a keylock window. The power output shaft and a gear-reversing gear are locked and the power output shaft outputs a reactive torque so as to realize the gear-reversing function. The sliding shaft keylock gear transmission has the advantages of less gear assemblies, reliability in use, simple machining process, light weight and the like and can be widely applied to the field of carrying tools.
Description
Technical field
The present invention relates to a kind of automobile-used gear-shift transmission, the axle key that particularly slides lock gear-shift transmission belongs to the apparatus of transport field.
Background technique
Simply, cheaply, reliably speed changer is the research direction of speed changer always, present speed changer structure comparatively speaking, and is too complicated, makes that the speed changer cost is too high.How to separate invent out the most simply, the most reliably gear arrangement is extremely important problem.In patent " slip axle key lock gear-shift transmission ",, need avoid this shortcoming because the design proposal of covering plate causes pto long.
Summary of the invention
Technical problem to be solved by this invention provides a kind of slip axle key lock gear-shift transmission, can substitute existing step change transmission.Have: simple in structure, cost is extremely low, uses reliable; Gear assembly is few, and is in light weight, and volume is little.
The present invention's scheme that the technical solution problem of axle key lock gear-shift transmission adopted of sliding is: the present invention is made up of main gear reducer structure, driving gear, pto, speed change gear, speed ring, gearshift, gearbox case.
Basic structure is: clutch is connected with main drive gear, and power input shaft is equipped with main drive gear, this gear and final gear engagement, and final gear is connected fixing with driving gearshaft through the gear retainingf key, and be provided with the final gear outer cover.
Elementary deceleration: clutch is connected with power input shaft; Motor is imported power input shaft through clutch with power; Power input shaft drives main drive gear and rotates, this gear and final gear engagement, and final gear is connected with driving gearshaft through the gear retainingf key and fixes; So just realize elementary deceleration, made driving gearshaft be in suitable speed range.In order to protect final gear and reverse gear, and better fixed conveyor gear shaft and main drive gear, the final gear outer cover be provided with.
The formation of speed change gear: in the transmission gear case, driving gearshaft is connected fixing with 8 driving gears through the gear retainingf key, be provided with the gear isolating ring between each driving gear, makes not interfere between driving gear.In the speed-change gear box cavity, pto is equipped with 8 speed change gears, and each retaining driving gear and corresponding speed change gear engagement constitute an independently gear, are provided with the gear isolating ring between each speed change gear, make not interfere between speed change gear.Speed change gear freely rotates on pto.Because all driving gear and corresponding speed change gear mesh; When the key lock was in non-blocking, the rotation of driving gearshaft drove all speed change gears and rotates with different rotating speed, and speed change gear freely rotates with respect to pto; Do not have power output, show as the neutral state.In order to reduce the weight of gear-box, gear all adopts the web gear structure.
The working procedure of slip axle key lock gear-shift transmission: in order to realize speed-regulating function, need be processed with the gear locking slot at speed change gear, and in pto the fitting key lock device.Under the rotation condition, speed change gear can freely rotate.On pto, be provided with nine key lock windows, the key lock can reach pto through key lock window and enter into outward in the speed change gear locking slot, realizes the locking of pto and corresponding reduction gear, plays the effect of gear retainingf key.Realize the locking of pto and a certain retaining driving gear Dynamic Coupling.
The structure of pto: processing key lock is installed hole slot in key lock sliding axle, fitting key lock in dead slot, and two symmetrical key locks are fixedly connected spring stationary axle and spring fixed axle sleeve respectively, lay key lock spring on the fixed axle sleeve, constitute the key lock device.Be processed with key lock shaft slip cavity at pto, key lock sliding axle is inserted into key lock shaft slip cavity and constitutes a complete axle.
Speed regulating mechanism working principle: in the process of speed governing, drag the position that key lock sliding axle changes the key lock, select the speed change gear of a certain gear of locking, so just realize the gear adjustment easily through changing gear.In the process of adjustment gear, key lock sliding axle is inserted in the pto and can rotates thereupon on the one hand, and key lock sliding axle can freely slide in key lock shaft slip cavity again on the other hand, and this function realizes through speed ring.End at key lock sliding axle is equipped with speed ring; Speed ring is made up of speed ring inner ring and speed ring outer ring; The speed ring ball is arranged between the two-layer ring; Have bearing structure, the speed ring inner ring is connected fixing with key lock sliding axle through speed ring inner ring and key lock sliding axle set screw, speed ring outer ring welded and installed speed ring driving lever.Speed ring is covered with speed ring driving lever movement slots outward.The key lock sliding axle that such structure makes the speed ring driving lever to drag and is in rotary state is done axial motion.Concrete gearshift is to realize speed governing through stirring the speed governing shift handle.Rotating shaft of speed governing shift handle and speed governing shift handle support are hinged, and speed governing shift handle lower end is a selector fork, flexibly connect with the speed ring driving lever.When stirring the speed governing shift handle, selector fork is stirred the speed ring driving lever and in speed ring driving lever movement slots, is seesawed, and changes the position of key lock on the key lock sliding axle, realizes the speed governing gearshift.
Gear reversing function: when the non-state that reverses gear is worked, reverse gear idle running.When extension reverses gear, through speed ring driving lever pulling key lock sliding axle, make the key lock from key lock window, eject, pto and reverse gear are locked, and the driving gear that reverses gear counter-rotating drives the pto counter-rotating, and the output countertorque realizes gear reversing function.
Beneficial effect of the present invention and remarkable progress are: realized the gearshift function, have simple in structure, cost is extremely low, use reliable, gear assembly is few, processing technology is simple, in light weight, advantage that volume is little.
