Central power output and rear power output device of tractor

Abstract

The invention discloses a central power output and rear power output device of a tractor, which is controlled by adopting a hydraulic controlled type power output clutch, has reasonable design and simple and direct structure and comprises a power input shaft, a power output clutch, a hydraulic control valve, a rear axle shell, a power transmission shaft, a transmission gear set, a rear power output shaft, a central power output shaft and a rear power output shift operating device. The hydraulic controlled power output clutch is adopted to eliminate the inertia force generated when a driven farm machinery is separated, and the power output clutch is internally provided with a special braking component, so once the power output clutch is separated, the braking element can come into play so as to enable the power output shaft to rapidly stop rotation, thus preventing the power output shaft from being damaged while lifting. Therefore, the central power output and rear power output device can meet the structural requirement on the tractor to be matched with various farm machinery, favorably solves the key technology of central power output of the tractor and improves the complete machine performance and application scope of the tractor.

Description

technical field [0001] The invention belongs to the field of tractors, and relates to a tractor mid-mounted power output and rear-mounted power output device. Background technique [0002] At present, the wheeled tractor products developed by our country have greatly improved in the matching and application of agricultural machinery, especially the rear power output device has basically tended to perfection. With the rapid development of agricultural mechanization, the types of operations are gradually increasing. A large number of modern operation methods such as single operation and compound operation require more and more types of agricultural machinery and tools for tractors, and the supporting methods tend to be diversified. In addition to the commonly used rear suspension and rear power take-off, there are also a large number of work tools that require various power output devices such as front suspension, front power take-off, mid-mounted suspension, and mid-mounted ...

AI Technical Summary

Problems solved by technology

Compared with the advanced technology of foreign tractors, the research and application of domestic tractors in the mid-mounted power output is still relatively lagging behind. The structure of small and medium power tractors in the existing technology is relatively compact, and the input shaft of the front drive axle is arranged under the rear axle housing, which is not enough. In addition, the rear power output shaft of many small and medium power tractors has only one fixed speed, which limits the types of supporting agricultural machinery and reduces the performance and application range of the tractor.
