A miniature hinged steering loader drive system

Abstract

The invention discloses a miniature hinged steering loader drive system, comprising a front rim and a rear rim, a front tire mounted on the front rim and a rear tire mounted on the rear rim. The miniature hinged steering loader drive system also comprises an engine and a hydraulic pump connected with a power output end of the engine, wherein the hydraulic pump is connected with a front motor through a front hydraulic oil pipe and is connected with a rear motor through a rear hydraulic oil pipe. The power output end of the front motor is connected with the power input end of a front differential assembly througha front reduction gear set, and the power output end of a rear motor is connected with the power input end of a rear differential assembly through a rear reduction gear set. The power output ends on both sides of the front differential assembly are respectively connected with the front rim through the front half axle. The power output ends on both sides of the rear differential assembly are connected to the rear rim through the rear axle halves. The miniature hinged steering loader drive system combines the mechanical transmission and the hydraulic transmission, reduces the displacement of the hydraulic pump and the motor, simultaneously eliminates the transmission shaft, and has the advantages of simple structure, space saving and high transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission systems, in particular to a miniature articulated steer loader transmission system. Background technique [0002] At present, the miniature articulated steer loader is more and more favored by many small farms, construction sites and breeding places due to its small body and compact structure. At the same time, the requirements for the external dimensions and configuration of its transmission system are relatively high. There are three main types of existing transmission systems suitable for mini loaders: one is mechanical transmission, the power output by the engine is transmitted to the front and rear drive axles through the gearbox and transmission shaft; the other is mechanical-hydraulic hybrid transmission, the power output by the engine It is transmitted to the high and low gear box through the hydraulic pump and motor, and then transmitted to the front and rear drive axles thr...

AI Technical Summary

Problems solved by technology

[0003] However, there are still many problems in the existing transmission system: the mechanical transmission structure is complicated, the required transmission parts are many, and the layout space requirements are large, which cannot meet the requirements of the miniature loader for the small size; the mechanical-hydraulic hybrid transmission is due to the The hydraulic pump and motor are installed on a simple high-low gearbox, which takes up a lot of space. The structure is too compact, which is not convenient for the arrangement of the transmission shaft, and it is not convenient for maintenance and service; the hydrostatic transmission requires a large displacement of the hydraulic pump and motor. When the whole machine is fully loaded and working in a harsh environment, the transmission efficiency is low and the cost is high

Therefore, the existing transmission system still has problems such as low efficiency, large space occupation, and complex structure in actual use.
