Compared with the prior art, the small-size four-wheel drive stepless speed change loader of the invention has the characteristics of reasonable design, simple structure, easy use and the like, thereby effectively simplifying operations and improving work efficiency.

Description

technical field [0001] The invention relates to a loader, in particular to a small four-wheel drive continuously variable speed loader. Background technique [0002] Currently in the small load market, the economical loader with the largest production and sales volume has the overall structure: a reverse six-bar working device, a bent front and rear frame, a single-cylinder engine, a modified tractor 6+1 gearbox, and a four-wheel drive. The power transmission route of the walking system is: single-cylinder engine flywheel → driving pulley → driven pulley → gearbox input shaft → gearbox output shaft → front and rear axle half shaft output. This design scheme has been verified by the market for a long time, and basically meets the general use requirements. However, there are three major defects in this transmission method. One is that the working efficiency is low and the engine power cannot be fully utilized; the other is that frequent gear changes are required, which is inc...
