The utility model has favorable reverse running performance, and the foot pedal manipulation is flexible and convenient; the utility model adopts sealing engine oil lubrication and a rolling bearing, and therefore, the utility model has the advantages of high drive efficiency, long service life and convenient installation.
Description
The utility model relates to a kind of reverse gear mechanism, especially motor tricycle external reverse gear mechanism.
At present, the motor tricycle of domestic most of manufacturer production manufacturings can only advance and travel, can not reverse travel.This defective makes the development of motor tricycle and prospect be hindered and influence, and in use, the overslaugh order of traffic appears in regular meeting, and problem such as cause the accident.Though there are some motor tricycle gear reversing devices to come out, complex structure, unstable properties, what all adopt is grease lubrication, and is hand shift, therefore uses inconvenient.
The purpose of this utility model provides a kind of motor tricycle external reverse gear mechanism, improves the in-use performance and the maneuvering performance of the motor-driven reverse travel of motor tricycle.
Concrete scheme of the present utility model is: comprise drive sprocket, bearing, driven sprocket, main shaft, nut, regulating control, it is characterized in that: mandrel is housed in main shaft, and an end of mandrel is connected with backguy, and the other end links to each other with spline gear by finger; The external end head of backguy is connected with reverse lever; Spline gear is an inside spline wheel gear, and it and drive chain wheel seat are slidingly connected, and a side of spline gear has dog, this dog be sleeved on main shaft on transmission gear on groove corresponding; Casing is hung on the cramp bar, and cramp bar is hung on the supporting base; In casing, gear is housed through bearing.
Adopt such scheme to have the reverse travel function, foot-operated reversing, manoeuvrable, dependable performance; Since adopt leakproofness oil lubricating and antifriction-bearing box, the driving efficiency height, long service life, easy for installation.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is integral structure figure of the present utility model;
Fig. 2 is the structural representation of reverse gear base portion (box inner structure) among Fig. 1;
Fig. 3 is Fig. 2 middle gear transmission scheme drawing;
Fig. 4 is that the K of Fig. 1 is to figure.
As shown in Figure 1 and Figure 2: the utility model mainly is made up of backguy 1, mandrel 2, bearing 3, drive sprocket 4, bearing 5, transmission gear 6, spline gear 7, driven sprocket 8, bearing 9, finger 10, bearing 11, main shaft 12, gear 13 and 14, casing 15, nut 16, regulating control 17, nut 18, nut 19, regulating control 20, nut 21, cramp bar 22, supporting base 23, reverse lever 24, drive chain wheel seat 25.This
The architectural feature of utility model is: mandrel 2 is housed in main shaft 12, and an end of mandrel 2 is connected with backguy 1, and the other end links to each other with spline gear 7 by finger 10; The external end head of backguy 1 is connected with reverse lever 24; Spline gear 7 is the male splines gear, and it and drive chain wheel seat 25 are slidingly connected, and a side of spline gear 7 has dog, this dog be sleeved on main shaft 12 on transmission gear 6 on groove corresponding; Casing 15 is hung on the cramp bar 22, and cramp bar 22 is hung on the supporting base 23; In casing 15, gear 13 and 14 are housed through axle (II, III).
Also can further learn from Fig. 2: transmission gear 6 is sleeved on the main shaft 12 through bearing 11, and its end connects with driven sprocket 8, simultaneously, and transmission gear 6 and gear 13 engagements.
As shown in Figures 2 and 3: spline gear 7 release the drive gears 6 backs and gear 14 engagements, gear 14 and gear 13 engagements.Spline gear 7 is slidingly connected with drive chain wheel seat 25, and the endoporus of drive chain wheel seat 25 is internal splined holes.
The utility model is performed such work: earlier the utility model is installed on the motor bike, wherein main shaft 12 two ends are fixed on the former frame of motorcycle by nut 16,18,19,21, casing 15 hangs to be wanted on the cramp bar 22, cramp bar 22 is hung on the supporting base 23, connect with vehicle frame by supporting base 23, and can be by adjusting casing 15 positions such as regulating controls 17,20.Reverse lever 24 is socketed on the former car stretcher.Start the engine the utility model enters work.Drive path is as follows:
1. advance (forward) travel: drive sprocket 4 drives spline gears 7 and rotates, and spline gear 7 combines as a whole with transmission gear 6 and driven sprocket 8, and rotation direction is identical, just finishes and changes.At this moment, gear 13 and 14 idle running.
2. reversing (oppositely) is travelled: foot-operated reverse lever 24, backguy 1 and mandrel 2 break away from spline gear 7 and transmission gear 6, gear 7 and gear 14 engagements, and its drive path is: 4-7-14-13-6-8, drive sprocket 4 is opposite with driven sprocket 8 rotation directions, realizes reversing.
