Abstract

The great-tonnage low-speed tractor includes chassis with front drive axle, back drive axle, driver cab and engine, the engine is connected via hydraulic torque converter to gear box, the gear box isconnected to front and back drive axles via the transmission shaft, and the chassis includes the front chassis and the back chassis hinged together. The tractor has high low speed stability, good heavy load starting characteristic, smooth gear shift, all-wheel drive, great traction, disc brack suitable for frequency braking, light and flexible steering and small turn radius. It is suitable for iron and steel works and other enterprise to perform low-speed short-distance great-tonnage transportation in narrow space.

Description

Technical field [0001] The invention relates to a wheeled tractor, which belongs to a transportation vehicle. Background technique [0002] At present, ordinary tractors are mainly designed for long-distance and highway transportation, and the transmission system mainly adopts mechanical transmission. [0003] Special transportation in iron and steel enterprises, ports and other factories has the characteristics of large tonnage, low speed, short distance, frequent heavy-load starting, and good road conditions. Under such transportation conditions, the use of ordinary tractors has the following shortcomings: 1. Low speed and poor stability; 2. Frequent heavy-load starting and serious clutch damage; 3. In order to generate large traction, equipped with high-power engines, and serious power waste: 4. .The minimum turning radius is large and requires a larger work site. Summary of the invention [0004] The purpose of the present invention is to develop a large-tonnage low-speed tr...
