Abstract

The utility model relates to a reversing device for a planetary gear. The utility model is characterized in that a stationary shaft is a hollow shaft, a restoring spring is arranged in the stationary shaft, the tail end of the spring and the end head of the stationary shaft are provided with inner deflector rods, and the middle part of the stationary shaft is provided with a chute; the chute is sheathed with a spline sliding bush, and a teasing pin on the spline sliding bush falls into the chute of the stationary shaft. A planetary shaft sleeve is arranged on the spline sliding bush. A driven bevel gear and a drive bevel gear are connected with a driven sprocket and a drive sprocket through a drive plate. A spline positioning sleeve is arranged between a drive gear and the spline sliding bush, and is fixed on the stationary shaft. The device adopts a built-in structure, and mud is not easy to enter. The utility model has the advantages of compact structure, convenient use and labor saving, and the structure of an original car is not changed when the utility model is arranged.

Description

The planetary wheel reversing arrangement

The utility model relates to a kind of reversing gear, especially the planetary wheel reversing arrangement.

At present, the three-wheel vehicle of public use and simple and easy car all do not have reversing gear mostly on the market, use very inconvenient.Chinese patent 97210025.3 discloses " a kind of motor tricycle reversing arrangement ", though this device can be realized reversing, be exposed structure because its adopts, thereby silt easily immerse in the power-transfer clutch, cause power-transfer clutch work dumb, out-of-control phenomenon often occurs.In addition, this patent in the outer setting of driving device outrigger, make structure complicated, cost height not only, volume is big, and need change primary car structure when being installed on the car, therefore, installs also inconvenient.

The purpose of this utility model provides a kind of planetary wheel reversing arrangement that need not change primary car structure, by built-in epicyclic gear transmission, solves the reversing problem of three-wheel vehicle and uses installation question.

Concrete scheme of the present utility model is: comprise dead axle, driven sprocket, driven wheel of differential, left shell, planet axis, right casing, satellite gear, drive bevel gear, drive sprocket, it is characterized in that: dead axle is a hollow shaft, retracing spring is housed in dead axle, at spring tail end and dead axle termination interior driving lever is housed, middle part at dead axle has chute, at chute place suit spline sleeve, the finger on the spline sleeve falls in the chute of dead axle; Planet axis is sleeved on the spline sleeve; Driven wheel of differential is connected with drive sprocket with driven sprocket through dial with drive bevel gear; Arranged outside at drive sprocket has the spline piece; The spline locating bush is arranged between driving gear and spline sleeve, and the spline locating bush is fixed on the dead axle.

Adopt the such scheme compact conformation, volume is little, and is easy for installation, need not change primary car structure, handling ease, and cost is low, and the planet reversing arrangement adopts totally enclosed, and mud can't enter less, and is safe in utilization and convenient.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

From above-mentioned accompanying drawing as can be known: the utility model is by dead axle 1, driven sprocket 2, dial 3, driven wheel of differential 4, left side shell 5, planet axis 6, right casing 7, satellite gear 8, drive bevel gear 9, drive sprocket 10, dial 11, spline piece 12, retracing spring 13, interior driving lever 14, spline locating bush 15, finger 16, spline sleeve 17, bearing 18 is formed, architectural feature of the present utility model is: dead axle 1 is a hollow shaft, retracing spring 13 is housed in dead axle 1, driving lever 14 in be equipped with spring 13 tail ends and dead axle 1 termination, 10 ones 3 have chute in dead axle 1, at chute place suit spline sleeve 17, the finger 16 on the spline sleeve 17 falls in the chute of dead axle 1; Planet axis 7 is sleeved on the spline sleeve 17; Driven wheel of differential 4 is connected with drive sprocket 10 with driven sprocket 2 through dial 3 or 11 with drive bevel gear 9; Arranged outside at drive sprocket 10 has spline piece 12; In drive bevel gear 9 and 17 of spline sleeves spline locating bush 15 is arranged, spline locating bush 15 is fixed on the dead axle 1.

As shown in Figure 1: on the internal diameter of driven wheel of differential 4, have spline.

As shown in Figure 2: two of planet axis 7 is installed in the through hole of left shell 5 and right casing 7 handing-over places formations.

The utility model is performed such work: when just changeing, spline sleeve 17 is moved to the left under the promotion of retracing spring 13 and finger 16 with driven wheel of differential 4 internal diameter splines and meshes; When drive sprocket 10 rotations, driven wheel of differential 4 becomes a rigid body with driven sprocket 2 and left and right sides shell 5 and 7 and can't rotate arbitrarily under spline sleeve 17 effect, this moment, drive sprocket 10 was equivalent to turning wheel, drive sprocket 10 rotate drive left and right sides shells 5 and 7, planet axis 6, satellite gear 8, driven wheel of differential 4, dial 3 and 11 and driven sprocket 2 rotate in the same way in the lump, thereby realize just changeing.When needing counter-rotating, only need interior driving lever 14 is spurred to the right, spline sleeve 17 moves right under finger 16 effects,

spline sleeve

17 and 15 engagements of spline locating bush; When drive sprocket 10 forward rotation, drive bevel gear 9 drives satellite gear 8 and rotates, and satellite gear 8 drives driven wheel of differential 4 contrarotations, and driven wheel of differential 4 drives driven sprocket 2 backward rotation, thereby realizes counter-rotating.
