Abstract

The invention relates to a multi-function four-wheel drive transfer case. The multi-function four-wheel drive transfer case comprises a case body assembly, an input shaft assembly, a middle shaft assembly, a four-wheel drive shaft assembly, a high-low gear fork shifting assembly and a driving gear fork shifting assembly. An input shaft duplicate gear of the input shaft assembly consists of an input shaft high-speed gear and an input shaft low-speed gear, and the input shaft high-speed gear and the input shaft low-speed gear can separately mesh with a middle shaft high-speed gear and a middle shaft low-speed gear. A rear axle combining sleeve and a front axle combining sleeve of the four-drive axle assembly mesh with a rear axle and a front axle separately, a driving gear front shifting fork and a driving gear rear shifting fork can separately drive the front axle combining sleeve and the rear axle combining sleeve to move in the axial direction of the front axle and the rear axle, thefront axle combining sleeve and the rear axle combining sleeve can mesh with a four-wheel drive driven gear in a sleeving connection mode, and the four-wheel drive driven gear meshes with a middle shaft transmission gear. The multi-function four-wheel drive transfer case can realize the rear wheel drive of a transport vehicle provided with the multi-function four-wheel drive transfer case when driving on a good road surface, the front wheel drive is adopted when driving on a non-hard road surface, and the four-wheel drive is adopted when climbing on low speed or crawling.

Description

technical field [0001] The invention belongs to the technical field of transfer case, in particular to a multifunctional four-wheel drive transfer case. Background technique [0002] There are three main types of car drive: front-wheel drive, rear-wheel drive, and four-wheel drive. Four-wheel drive systems currently used in passenger cars mainly include part-time four-wheel drive, timely four-wheel drive and full-time four-wheel drive. Among them, since the part-time four-wheel drive system does not have an inter-axle differential, the driver needs to choose a four-wheel drive or two-wheel drive solution according to the road conditions. Improper selection can easily lead to internal power flow consumption of the drive system. Timely four-wheel drive can overcome the shortcomings of time-sharing four-wheel drive. Its principle is to use computer technology to judge road conditions and automatically select two-wheel drive or four-wheel drive. This system is usually used in h...
