Abstract
The utility model relates to a backing device for a motor tricycle, which is characterized in that a centre shaft is sheathed with a driven disk through a needle roller bearing. The driven disk is sheathed with a cover plate, a body, a driving disk and a turning sleeve. The turning sleeve is sheathed with an in-out gear. A tension spring is arranged between the in-out gear and a turning disk. The in-out gear is engaged with the driving disk by a pinion which is arranged on the body via a minor shaft. One end of the turning sleeve is engaged with the driving disk or the in-out gear, and the other end is connected with a shifting fork which is sheathed on a guiding shaft sheathed with the tension spring. The utility model has the advantages of compact structure, small size, no need of changing the original structure of the motorcycle and convenient installation and use, and the forward and reverse rotation of the motorcycle can be realized by pulling or loosening a pull wire.
Description
The utility model relates to a kind of reversing gear, especially a kind of positive three-wheel vehicle reversing gear.
The positive three-wheel vehicle of Chu Shouing does not all have reversing gear in the market, in the turnover garage, gives way or when reversing end for end, the people must get off and just can carry out, and uses extremely inconvenient.Chinese patent 97243327.9 discloses a kind of " motor bike external reverse gear unit ", though this gear reversing device can be realized reversing, and complex structure, volume is big, and being installed in needs to change primary car structure on the motor bike, install inconvenient.
The purpose of this utility model provides a kind of positive three-wheel vehicle reversing gear that need not change primary car structure, realizes forward and reverse running by this reversing gear is installed on the vehicle body between the firsts and seconds chain.
Concrete scheme of the present utility model is: be set with clutch plate through needle bearing on axis, be set with cover plate, body, driving disc spacing pressing and turning sleeve on clutch plate; On turning sleeve, be set with interior external gear, between interior external gear and the steering handwheel extension spring arranged; Interior external gear is by the engagement of miniature gears and driving disc spacing pressing, miniature gears through little axle mounting on body; One of turning sleeve and driving disc spacing pressing engagement or inside and outside gear mesh, the other end is connected with shift fork, and shift fork is sleeved on the axis of guide that is with extension spring, and the backguy of shift fork is stretched out originally external.
Adopt the such scheme compact conformation, volume is little, need not change the primary car structure of motor bike, and forward and reverse rotation of motor bike only need spur or loosen backguy and can realize, installation and use are all very convenient.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is integral structure figure of the present utility model, also is a kind of embodiment of the present utility model.
As can be seen from Figure 1: the utility model is made up of body 1, driving disc spacing pressing 2, turning sleeve 3, collar 4, seal ring 5, key 6, needle bearing 7, extension spring 8, interior external gear 9, backguy 10, rubber card pad 11, the axis of guide 12, shift fork 13, axis 14, clutch plate 15, cover plate 16, bearing 17, dust boot 18, little axle 19, miniature gears 20.Architectural feature of the present utility model is: be set with clutch plate 15 through needle bearing 7 on axis 14, be set with cover plate 16, body 1, driving disc spacing pressing 2 and turning sleeve 3 on clutch plate 15; External gear 9 in being set with on turning sleeve 3 has extension spring 8 between interior external gear 9 and the turning sleeve 3; Interior external gear 9 is by miniature gears 20 and driving disc spacing pressing 2 engagements, and miniature gears 20 is installed on the body 1 through little axle 19; 3 one of turning sleeves and driving disc spacing pressing 2 engagements or 9 engagements of interior external gear, the other end is connected with shift fork 13, and shift fork 13 is sleeved on the axis of guide 12 that is with extension spring, and the backguy 10 of shift fork 13 is stretched out outside the body 1; Axial restraint is made by boss on the axis 14 and collar 4 in driving disc spacing pressing 2 and clutch plate 15 both sides.
Also can further find out from Fig. 1: clutch plate 15 is "T"-shaped, and cover plate 16, body 1, driving disc spacing pressing 2 and turning sleeve 3 are sleeved on the center pin of clutch plate 15.Turning sleeve 3 is sleeved on the center pin of clutch plate 15 by key 6.Driving disc spacing pressing 2 is species stage inner geares, its medium and small internal tooth and turning sleeve 3 engagements, big internal tooth and miniature gears 20 engagements.Both sides at driving disc spacing pressing 2 and clutch plate 15 are equipped with dust boot 18.
The utility model is performed such work: earlier axis 14 is installed on the vehicle body of I and II chain junction before the work, driving disc spacing pressing 2 is connected with the drive sprocket of motor bike, and clutch plate 15 is connected with the driven sprocket of motor bike.When pulling backguy 10, shift fork 13 is moved to the left, and drives turning sleeve 3 to moving to left, and this moment, turning sleeve 3 meshed with driving disc spacing pressing 2.When the drive sprocket of motor bike and chain drive driving disc spacing pressing 2 and are just changeing, driving disc spacing pressing 2 drives miniature gears 20 and turning sleeve 3 forward rotation, external gear 9 idle running in miniature gears 20 drives, turning sleeve 3 drives clutch plate 15 forward rotation by key 6, thereby realizes the just commentaries on classics of motor bike.When loosening backguy 10, shift fork 13 moves right under the spring force effect, turning sleeve 3 moves right thereupon, at this moment turning sleeve 3 meshes with interior external gear 9, and when driving disc spacing pressing 2 forward rotation, miniature gears 20 is just changeing, external gear 9 backward rotation in driving, interior external gear 9 drives turning sleeve 3 counter-rotatings, and turning sleeve 3 drives clutch plate 15 counter-rotatings by key 6, thereby realizes the backward rotation of motor bike.
