Description

Technical Field

[0001] The utility model relates to the technical field of four-wheel drive transfer cases, in particular to a heavy-duty four-wheel drive transfer case with a hand brake specially used for a gourd harvester of agricultural equipment. Background Art

[0002] Because the gourd harvester has a compact structure and is difficult to arrange, most of the gourd harvesters in China are harvesting in Xinjiang, where the working environment is harsh and the operation time is long. The gourd harvesters themselves are heavy agricultural machinery, and after starting to work, the vehicle is heavy at the back and light at the front (there is a large grain silo at the rear end), which places great demands on the four-wheel drive east-west distribution output. Most of the ordinary four-wheel drive transfer cases on the market can no longer meet the rigid use requirements of gourd harvesters in Xinjiang.

[0003] In order to better meet the requirements of parking on a slope, the existing transfer cases generally come with a hand brake system. However, the existing heavy-duty agricultural machinery four-wheel drive transfer cases have the disadvantage of insufficient power distribution. For the case of a special heavy-duty four-wheel drive transfer case with a hand brake, the internal transmission gear modulus is large, which leads to a messy distribution of the internal transmission shaft and a complex overall structure, which makes it inconvenient to regularly inspect and maintain the transfer case transmission shaft in the later stage. Utility Model Content
