Abstract
The utility model relates to a coaxial reverse gear gearbox for motor tricycles. The utility model is characterized in that an output splined shaft which is a hollow shaft is free sheathed on an input splined shaft in the same axial line; an input splined gear 4 and an output splined gear 5 are respectively in key connection with the intput splined shaft and the output splined shaft, the input splined gear 4 and the output splined gear 5 are respectively provided with a convex claw, wherein, the output splined gear 5 is driven by a shifting fork to move left and right on an output shaft to complete disembodiment and achieve forward and reverse rotation control; a wide gear idle 11 is respectively engaged with the input splined gear and a B gear idle, and an A gear idle 7 is engaged with the output splined gear 5. The utility model has the advantages that all gear idles are in free run when the utility model is in a forward gear state, the mechanical abrasion is lowered, and the service life of the utility model is raised.
Description
The utility model relates to the reverse gear case of motor-tricycle, specifically is a kind of coaxial reverse gear case of motor tricycle that secondary chain-drive, the frictional loss in the time of reducing mechanical drive are arranged.
In the prior art, when the reverse gear case of motor-tricycle is operated in the same way, need to bear frictional loss at full capacity and to be not less than 4% power transmission loss through secondary gear pair, four gear clusters.Efficient is low, and be restricted service life.
The purpose of this utility model is: provides a kind of and only realizes rotating control at same axle two ends, and when being operated in the same way, the input and output shaft through-coupling, all gear idle running, efficient 100%, and do not have the coaxial reverse gear case of worn-down motor tricycle.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, it is the coaxial reverse gear case of a kind of motor tricycle, comprise casing, input castellated shaft, output spline, input spline gear and output spline gear, by shift fork, gap bridge spline I axle, the keyed jointing gap bridge A gear and the gap bridge B gear thereon of gear shift operation bar control, gap bridge spline II axle, keyed jointing gap bridge wide gear thereon; It is characterized in that: output spline is a hollow shaft, is enclosed within on the input castellated shaft in the same axis sky; Input spline gear and output spline gear respectively with input castellated shaft and output spline keyed jointing, respectively have dog on input spline gear and the output spline gear, wherein export spline gear and drive sway on output shaft, finish and import the interlocking of dog of castellated shaft or disengaging and realize rotating control by shift fork; The gap bridge wide gear respectively with input spline gear and gap bridge B gear mesh, gap bridge A gear and the engagement of output spline gear.
Said structure of the present utility model is further specified by accompanying drawing.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a structure side view of the present utility model;
Accompanying drawing is the A-A echelon sectional view of accompanying drawing 1.
Referring to accompanying drawing: the coaxial reverse gear case of the motor tricycle among the figure, comprise casing 1, input castellated shaft 2, output spline 3, input spline gear 4 and output spline gear 5, by shift fork 6, gap bridge spline I axle 8, the keyed jointing gap bridge A gear 7 and the gap bridge B gear 9 thereon of gear shift operation bar control, gap bridge spline II axle 10, keyed jointing gap bridge wide gear 11 thereon; It is characterized in that: output spline is a hollow shaft, is enclosed within on the input castellated shaft in the same axis sky; Input spline gear 4 and output spline gear 5 respectively with input castellated shaft and output spline keyed jointing, respectively have dog on input spline gear 4 and the output spline gear 5, wherein export spline gear 5 and drive sway on output shaft, finish disengaging and realization rotating control by shift fork; Gap bridge wide gear 11 respectively with input spline gear and gap bridge B gear mesh, gap bridge A gear 7 and 5 engagements of output spline gear.
The working process of said structure is such: when shift fork drive that the output spline gear is moved to the left and the time, during with the interlocking of the dog of input castellated shaft, form the direct forward transmission of input and output shaft, at this moment, the idle running of other gear.When shift fork moves to right, dog is thrown off, tooth portion embeds gap bridge A gear 7 tooth portion engaged transmission simultaneously, the a left side half tooth portion engaged transmission of the gap bridge wide gear 11 because the gap bridge B gear 9 that keyed jointing is positioned at gap bridge spline I axle 8 left ends and keyed jointing are positioned to pass a bridge on the II axle 10,7 of gap bridge A gears and output spline gear engaged transmission, thus acquisition is through the reverse drive power of tertiary gear auxiliary driving between output spline and output spline.
The utility model is owing to the advantage that described structure has is: just keep off duty when device is in The time, all carrier gear idle running has reduced mechanical wear, has improved the service life of device.
