Problems solved by technology

[0002] The transmission gear system of traditional motor vehicles generally includes the transmission gear system in large vehicles such as automobiles. This system is generally equipped with a gearbox for speed change adjustment. The speed change adjustment range is relatively large, but the structure is complicated and the cost is high; The relatively simple gear is traditional. The gears in this gear system are arranged outside the wheels, and a group of large and small gears are used to cooperate to achieve the purpose of speed change. This gear system has a simple structure, but the range of speed change adjustment is small, and often cannot adapt to the speed change of vehicles. Require

Embodiment Construction

[0015] Such as figure 1 As shown, the first embodiment of the motor vehicle transmission gear system of the present invention includes a drive motor 1, a drive gear 2 is arranged on the drive shaft of the drive motor 1, an external gear 5 is arranged around the wheel shaft 4 on the wheel 3, and an external gear 5 is arranged on the wheel 3. 1. An internal gear 6 is arranged on the periphery of the external gear 5, and the drive gear 2 drives the internal gear 6 or the external gear 5, and the internal gear 6 or the external gear 5 drives the wheels to rotate. The outer gear 5 and the wheel 3 are connected and cooperated through the one-way clutch, and the inner gear 6 and the wheel 3 are connected and cooperated through the one-way clutch. 2 directly meshes with internal gear 6 and external gear 5.

[0016] The following briefly describes the operation mode of the motor vehicle transmission gear system in the first embodiment: 1. The driving motor 1 rotates forward (the so-ca...

Abstract

The invention discloses a transmission gear system of a motor vehicle. The system comprises a drive motor; a drive gear is arranged on a drive shaft of the drive motor; an external gear is arranged on a wheel and around an axle; an internal gear is arranged on the wheel and at the periphery of the external gear; the drive gear drives the internal gear or the external gear; and the internal gear or the external gear drives the wheel to rotate. Since the transmission gear system of the motor vehicle is provided with the smaller-diameter external gear and the larger-diameter internal gear, the internal gear and the external gear are arranged on the wheel, and the wheel has larger diameter, so that the internal gear conditionally has the diameter greater than that of the external gear, a larger gear ratio can be generated when the drive gear drives the wheel by the internal gear or the external gear respectively, and the purpose of substantially regulating variable speed is achieved. Moreover, the system, which is provided with the internal gear and the external gear, is simple in structure and low in cost, so that the cost performance of a product is greatly improved.
