Problems solved by technology

[0004] The existing transfer case that can realize full-time four-wheel drive is relatively complicated in structure, takes up a lot of space, and the assembly volume allocated to the vehicle power system has been greatly reduced. Therefore, it is difficult to realize the miniaturization of the vehicle and meet the needs of consumers for small Demand for four-wheel drive vehicles with full-time four-wheel drive

Embodiment Construction

[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] First of all, it needs to be explained that coaxiality is a kind of positioning tolerance. Specifically, it refers to the degree of deviation between two axes that are required to be on the same straight line on the part. The smaller the deviation, the higher the coaxiality.

[0042] Such as figure 1 and Figure 5 As shown, a vehicle transfer case provided by the first aspect of the present invention includes an input shaft 1 connected to the output end of the transmission, a first output shaft 2 connected to the rear axle, and a second output shaft connected to the front axle 3. The housing 4 and the clutch 5, wherein the input shaft 1 is provided with...

Abstract

The invention relates to a vehicle power distribution system, in particular to a vehicle transfer case which comprises an input shaft (1), a first output shaft (2) connected with a rear axle and a second output shaft (3) connected with a front axle. The compound planetary gear mechanism comprises a planet carrier, a first sun gear, a first planet gear set, a second sun gear, a second planet gear set, a first gear ring and a second gear ring, and the planet carrier can be selectively connected with the second sun gear through a clutch (5) so that torque of a front axle and torque of a rear axle can be distributed according to a fixed design proportion or distributed according to needs; the first gear ring is configured to be selectively connected with the shell (4) and the planet carrier so that torque of at least two gear transmission ratios can be output to the front axle and the rear axle through different combinations of the gear pairs. In addition, the invention further relates to a power assembly comprising the vehicle transfer case and a vehicle. The vehicle transfer case is compact in structure and small in size.

Description

technical field [0001] The invention relates to a vehicle power distribution system, in particular to a vehicle transfer case, and also to a power assembly and a vehicle. Background technique [0002] As consumers have higher and higher requirements for car handling performance and off-road performance, the four-wheel drive technology of vehicles has been developed rapidly. [0003] At present, most of the high-end models that pursue power use the four-wheel drive system of the front and rear drive, especially the full-time four-wheel drive system, so that the power output by the transmission is distributed to the front axle and the rear axle according to the required ratio from time to time through the transfer case. The four wheels and the ground have driving force, which greatly increases the dynamic performance of the vehicle, and the structural parameters of the transfer box directly affect the dynamics and safety of the transmission system, which is a key component of ...
