Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the present invention will be further described by specific embodiment:

[0039] See figure 1 , figure 2 , a power system of a crawler tractor, including an engine, a clutch 1 and an input shaft 2, the clutch 1 is in the form of a pull rod release fork. The power system also includes a power split mechanism, a power output mechanism, and a driving wheel travel mechanism; the power split mechanism includes a power split shaft 3 connected to the input shaft 2, a power output driving gear 31 located on the power split shaft 3, and an HST power input drive. Gear 32; the power output driving gear 31 is a spur gear, and the power output driving gear 31 is provided with two, which are divided into a high-speed gear and a low-speed gear, and the HST power input driving gear 32 is a bevel gear;

[0040] The power output mechanism includes an output shaft 4 that is arranged in sections and is connected to two adjacent stages of t...

Abstract

A power system of a crawler tractor includes an engine, a clutch and an input shaft, as well as a power split mechanism, a power output mechanism and a driving wheel traveling mechanism. The invention has a compact structure and is convenient to use, the structural strength of the output shaft is improved, the concentricity of the bearing position is guaranteed, it is not easy to be damaged, and the transmission efficiency is improved; The gears are arranged; the shock is reduced by the buffer device during steering braking, soft start is realized, and impact damage is avoided; it has the advantages of convenience and simplicity in the disassembly and replacement of components, and greatly reduces the difficulty and cost of maintenance.

Description

technical field [0001] The invention relates to the technical field of tractor power assembly, in particular to a power system of a crawler tractor. Background technique [0002] At present, domestic crawler tractors generally have the problems of unstable power output shaft performance and short service life. In actual work, after long-term use of the output shaft, there will be a large deviation in the concentricity of the bearing on the shaft, and the output shaft will oscillate in a circle while rotating, which will cause a great burden on the shaft and the box, and will frequently occur. Broken shaft or even the box is torn; and the actual test shows that in many cases, even if the concentricity is still relatively standard, the output shaft of the tractor will still be unable to withstand the torque and easily damaged when the tractor is working. Once the output shaft of these tractors is damaged, the entire gearbox must be disassembled to replace it. Factors such as ...
