Problems solved by technology

[0003] The function of the gearbox is to realize the transformation of the transmission ratio under the condition that the power output of the engine remains unchanged, so as to meet the requirements of power and economy under different road conditions; Therefore, gearboxes are mostly used in fuel vehicles, but most of the gearboxes on existing trucks are connected to the engine on the body, and transmit power to the wheels through a series of transmission mechanisms, resulting in a faster response speed of the wheels. Slow and intermediate processes consume more energy, and are less economical in the conditions of large-angle climbing and smooth driving

Description

technical field [0001] The invention relates to the technical field of hub driving devices, in particular to a three-speed hub driving device and a method for using the same. Background technique [0002] The small-tooth-difference gear transmission is an improvement of the ordinary planetary gear transmission. It is combined by a pair of internal meshing gear sets with a small difference in the number of teeth through eccentricity. Compared with the ordinary planetary gear transmission, this form is simple in structure and high in quality. Lightweight, small size, stable transmission, low noise, large transmission torque, can achieve a large transmission ratio, the input and output shafts can be on the same axis, or not on the same axis. [0003] The function of the gearbox is to realize the transformation of the transmission ratio under the condition that the power output of the engine remains unchanged, so as to meet the requirements of power and economy under different r...
