Tractor power high gear, power reversing and crawling gear combined transmission

Abstract

The tractor power high gear, power reversing and crawling gear combined transmission device is composed of two parts, a power shifting reversing device and a crawling gear device arranged in the box. One end of the power shifting reversing device is connected with the engine, and the other end is connected with the creeping gear One end of the gear device is connected, the other end of the crawling gear device is connected with the gearbox, and the input of the power shift reversing device is connected with the power output shaft; it can realize the functions of high and low power shifting, power reversing and crawling gear at the same time, and the transmission route is clear , compact structure, strong versatility of components. 48 forward gears and 24 reverse gears can be achieved through the combination of power shift reversing device, crawler gear device and gearbox 12-speed, the gear shifting is simple, the operation is convenient, the transmission is efficient, and the speed range is wide, which improves the tractor operation. adaptability and ease of operation.

Description

technical field [0001] The invention belongs to the technical field of tractors, in particular to a combined transmission device of a tractor power high gear, power reversing and crawling gear. Background technique [0002] Tractor power shifting and power reversing technology can realize shifting or reversing without cutting off the power, the operation is light and fast, and it has been widely used in European and American tractors. The power high and low gear (Hi-Lo) technology is only used for load switching between two gears, with simple structure and convenient control. It has been applied on tractors of many domestic manufacturers and has been well received by users. With the implementation of my country's rural revitalization strategy, the planting area of ​​economic crops has continued to expand. Special operations such as ditching, yam and medicinal material planting require tractors to have crawling speed, which has led to the rapid development of tractors with cr...
