Four-wheel drive transmission and four-wheel drive automobile

Abstract

The invention belongs to the field of transmissions, and discloses a four-wheel drive transmission and a four-wheel drive automobile. The four-wheel drive transmission comprises a power input shaft, atransmission gear pair, a front drive gear pair, a power output shaft, a rear axle power input shaft and a front drive power shaft, and each of the transmission gear pair and the front drive gear pair comprises two meshed gears. One gear of the transmission gear pair sleeves the power input shaft, and the other gear sleeves the power output shaft. One gear of the front drive gear pair sleeves thepower output shaft, and the other gear sleeves the front drive power shaft. The front drive power shaft is connected with a front axle through the transmission shaft, and the power output shaft is connected with the rear axle through the rear axle power input shaft. The front drive gear pair is arranged on the power output shaft, the power outputted by the power output shaft is transmitted to thefront axle through the transmission shaft by means of the front drive gear pair, and the power output shaft is connected with the rear axle through the rear axle power input shaft, so that the four-wheel drive is achieved. According to the present invention, few parts are adopted, an extra box body structure is not needed, the internal space of the transmission is fully utilized, and the cost islow.

Description

technical field [0001] The invention belongs to the field of transmissions, and relates to a four-wheel drive transmission and a four-wheel drive vehicle. Background technique [0002] The driving mode of four-wheel drive can have better off-road and handling performance at any time, and can prolong the service life of tires and improve the comfort of drivers. But at present, the power of the transmission is generally output from the rear end of the transmission to the rear axle. If the front drive is to be realized at the same time, it is generally necessary to add a transfer case. Pass all the way to the front bridge. [0003] However, when adding a transfer case, it is usually necessary to add an extra box body and many other components, resulting in an increase in cost and a tight space for the layout of the entire vehicle. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art that whe...
