Abstract

Provided is a full-wheel-drive tractor chassis driven by gears. According to the full-wheel-drive tractor chassis driven by the gears, a diesel engine, a front transmission case, front wheels, a steering control device, a trailer adapting piece, a rear transmission case, a trailer and rear wheels are installed on a support; a main shaft, a middle shaft and an auxiliary shaft which are installed in a gearbox are all spline shafts; a side transmission case is installed on the outer side face of the gearbox; one ends of the main shaft, the middle shaft and the auxiliary shaft in the gearbox extend into the side transmission case; the shaft heads of the main shaft, the middle shaft and the auxiliary shaft are provided with a main shaft auxiliary gear, a middle shaft auxiliary gear and an auxiliary shaft auxiliary gear respectively; the rear transmission case installed at the rear end of the gearbox is the rear transmission case below which an output cone gear shaft is located; the output cone gear shaft drives the rear wheels via a universal transmission joint, a rear transmission shaft and a rear axle assembly; due to the fact that the side transmission case is additionally arranged on the side face of the gearbox, a branch, distributed by the side transmission case, of the power transmitted by the gearbox is transmitted to the rear transmission case, the rear transmission case drives the rear transmission shaft through the universal joint, then the rear axle assembly drives the rear wheels to rotate, and the rear wheels and the front wheels rotate synchronously.

Description

technical field

[0001] The invention belongs to the technical field of tractor chassis, and relates to a gear transmission full-drive tractor chassis. Background technique

[0002] In the prior art, the direction control of the Dongfeng 12 walking tractor is controlled by the handrail, and the variant transporter of the Dongfeng 12 walking tractor is controlled by the steering wheel. The gearboxes of the two tractors are of the same type. A front transmission box is installed, and the front transmission box drives the front wheels to rotate, and only has the function of front-wheel drive. The front nose of this type of tractor and the trailer are hinged by the traction frame, which has the advantages of small turning radius, convenient operation and good driving comfort. In actual use, when encountering a slope or complex road surface, when the load is heavy, the tire adhesion is not enough, the front wheel is easy to slip or even tilt, and only has the front wheel drive fu...
