Transfer case assembly directly mounted in rear of gearbox and used for four-wheel drive rear wheel steering peanut harvester

Abstract

The invention relates to a transfer case assembly directly mounted in the rear of a gearbox and used for a four-wheel drive rear wheel steering peanut harvester. The transfer case assembly is characterized in that power is inputted by the gearbox, a gearbox gear is meshed with an idle gear mounted on an idle gear shaft of a transfer case, a first shaft, a second shaft and the idle gear shaft of the transfer case are distributed parallelly, each of the first shaft, the second shaft and the idle gear shaft is mounted on the transfer case through a pair of bearings respectively, a bevel gear shaft is perpendicular to the second shaft and assembled on one side of the transfer case, the idle gear on the idle gear shaft and a shaft gear portion of the first shaft are meshed with each other, a shaft gear on the first shaft and a second shaft driven gear on the second shaft are mutually meshed, a bevel gear wheel on the second shaft is meshed with the bevel gear shaft, the bevel gear wheel transmits power to rear drive axles, a shifting fork head is mounted in a groove of the second shaft driven gear, and whether transmitting power of the gearbox to the rear drive axles or not can be controlled by shifting a clutch arm so as to achieve switching between two-wheel drive and four-wheel drive.

Description

technical field [0001] The invention relates to a transfer case assembly directly installed at the rear of a gearbox for a four-wheel-drive rear-wheel steering peanut harvester, which belongs to the field of machinery. Background technique [0002] At present, the transfer case assembly of the four-wheel drive rear wheel steering peanut harvester developed in the domestic market is installed on the lower part and the right side of the gearbox assembly, and the drive shaft that transmits power to the rear drive axle can only be installed on the gearbox assembly. As a result, the ground clearance of the peanut harvester is small and the passability is poor. In order to improve the adaptability of the peanut harvester, a four-wheel drive rear wheel steering peanut harvester is specially designed with a transfer case assembly installed directly at the rear of the gearbox to increase the ground clearance of the peanut harvester. Contents of the invention [0003] The purpose o...
