Abstract

The invention discloses a two-gear four-wheel-drive transfer case system and a vehicle. The two-gear four-wheel-drive transfer case system comprises a driving wheel, two driven wheels, a first-gear clutch, a second-gear clutch, a first-gear driving gear and a second-gear driving gear, wherein pushing pieces are arranged on the two side faces of the driving wheel in the axial direction. The two driven wheels are respectively arranged on two sides of the driving wheel. Arc-shaped grooves are formed in the driven wheels, the pushing pieces are matched in the arc-shaped grooves, at least part of the groove bottoms of the arc-shaped grooves have gradients, and the directions of the gradients of the groove bottoms of the arc-shaped grooves in the two driven wheels are opposite. The first-gear clutch and the second-gear clutch are arranged on the sides, away from the driving wheel, of the two driven wheels correspondingly. The first-gear driving gear is connected with the first-gear clutch and matched with the first-gear driven gear, the second-gear driving gear is connected with the second-gear clutch and matched with the second-gear driven gear, and when the clutches are compressed, the corresponding driving gear can transmit torque to the corresponding driven gear. The driving wheel rotates forwards and backwards to extrude the driven wheels on the different sides respectively, then the clutch on the side is extruded, switching of the first gear and the second gear is achieved, the structure is simple, switching is convenient and fast, and cost is lower.

Description

technical field [0001] The invention relates to the technical field of transfer gears, in particular to a two-speed four-wheel drive transfer gear system and a vehicle. Background technique [0002] The four-wheel drive system is widely used in high-performance passenger cars. The transfer case is the core component of the four-wheel drive system and the basic component to realize the splitting of torque and power. The transfer case used in the four-wheel drive system is mostly a single-gear configuration. In order to increase the torque transmission range of the transfer case, the transfer case is designed as a two-speed structure. Most of the existing two-speed and clutch execution separation, this scheme has complex structure, great difficulty in processing and control, and high cost. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The object of the present invention is to provide a two-speed four-wheel dr...
