Abstract
The utility model relates to a reverse gear device for forward motor tricycles. The utility model is characterized in that a main shaft is a hollow shaft, the inner of the main shaft is provided with a resetting spring and a draw rod, one end of the draw rod is connected with an external spline sleeve through a sleeve pin, the other end of the draw rod is connected with a cam sleeve through a draw pin, and the cam sleeve contacts a cam inclined plane; one end of a center short shaft of a gear idle is fixed on a cover casing, the other end of the center short shaft is arranged on a center sleeve, and the center sleeve is sheathed on the external of the external spline sleeve; the left end surface of the external spline sleeve is a claw-shaped clutch, and the left end surface of the external spline sleeve corresponds the claw shape of a clutch sleeve which is sheathed between a left bevel gear and the main shaft. The utility model has the advantages of compact structure, flexible drive, easy fabrication, low cost and convenient operation.
Description
The utility model relates to a kind of reverse gear apparatus, especially the motor tricycle gear reversing device.
At present, the positive three-wheel vehicle of selling on the market does not have gear reversing device, motor bike in the turnover garage, give way or when reversing end for end, people's go-cart of must getting off just can be finished, thereby uses extremely inconvenient.In order to overcome inconvenient this defective of moveing backward, the gear reversing device of existing motor bike comes out now, but still there is such or such shortcoming in these gear reversing devices, as: volume is big, manufacturing is difficult, cost is high, service life is short etc.
The purpose of this utility model provides a kind of easily manufactured, the motor tricycle gear reversing device that cost is low.
Concrete scheme of the present utility model is: comprise driven sprocket, left angular wheel, carrier gear, right finishing bevel gear cuter, case, drive sprocket, minor axis, bearing, main shaft, key, it is characterized in that: the A. main shaft is a hollow shaft, retracing spring and pull bar are housed in main shaft, one on pull bar is connected with the male splines cover through hollow pin, the other end is connected with the cam cover through drawing pin, and the cam cover contacts with cam ramp; B. one of the central minor axis of carrier gear is fixed on the case, and the other end is installed on the center, and center is sleeved on outside the male splines cover; C. the left side of male splines cover is the curcumbitate power-transfer clutch, and this end face is corresponding with the curcumbitate that is sleeved on left angular wheel and main interaxle clutch cover.
Adopt the such scheme compact conformation, ensuring smooth transmission, easy to manufacture, cost is low, and is easy to operate, long service life.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a front view 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 mainly by driven sprocket 1, clutch cover 2, left angular wheel 3, carrier gear 4, hollow pin 5, center 6, male splines cover 7, right finishing bevel gear cuter 8, case 9, drive sprocket 10, pull bar 11, draw pin 12, cam cover 13, cam handle 14, cam 15, minor axis 16, retracing spring 17, bearing 18, main shaft 19, key 20 to form; Architectural feature of the present utility model is: A. main shaft 19 is hollow shafts, retracing spring 17 and pull bar 11 are housed in main shaft 19,11 1 on pull bar is connected through hollow pin 5 and male splines cover 7, and the other end is connected through drawing pin 12 and cam to overlap 18, and cam overlaps 18 and contacts with cam 15 inclined-planes; B. 16 1 of the central minor axis of carrier gear 4 are fixed on the case 9, and the other end is installed on the center 6, and center 6 is sleeved on outside the male splines cover 7; C. the left side of male splines cover 7 is the curcumbitate power-transfer clutch, and this end face is corresponding with the curcumbitate of the clutch cover 2 that is sleeved on 19 on left angular wheel 1 and main shaft.
Also can find out from Fig. 1: right finishing bevel gear cuter 8 is inside spline wheel gears, and it and male splines cover 7 mesh.
In Fig. 1: center 6 is a kind of inner spline housings, and it and male splines cover 7 mesh.
The utility model is performed such work: when drive sprocket 10 forward rotation, drive sprocket 10 drives right finishing bevel gear cuter 8 just to be changeed, at this moment, male splines cover 7 both meshed with right finishing bevel gear cuter 8, with center 6 engagements, at this moment whole train of gears and case 9 are a steel body, rotate in the same way with drive sprocket 10 again, so driven sprocket 1 is just changeing, motor bike is realized forward rotation.When needing counter-rotating, stir cam handle 14, cam 15 actuating cams cover 13 is moved, at this moment, cam cover 13 drives pull bar 11 and is moved to the left, hollow pin 5 drives male splines cover 7 and slides left, and at this moment, male splines cover 7 breaks away from right finishing bevel gear cuter 8 its end faces and clutch cover 2 engagements, the just commentaries on classics of right finishing bevel gear cuter 8 drives carrier gear 4 and rotates, and drive left angular wheel 3 counter-rotatings, left angular wheel 3 drives moving 1 counter-rotating of driven chains, so the time motor bike finish backward rotation.In the time need not reversing, only need hand to leave cam handle 14, pull bar 11 sets back under the effect of retracing spring 17, and male splines cover 7 meshes with right-hand member gear 8 again, and motor bike just changes again.
