Clutch-operation-free gearshift transmission for caterpillar equipment

Abstract

A clutch-operation-free gearshift transmission for caterpillar equipment comprises a main transmission assembly, an auxiliary transmission assembly, a proportional steering mechanism, a main reduction assembly, a power output transmission assembly and a clutch-operation-free gearshift assembly used for realizing direct gearshift only by operating a gear lever, which are all mounted in a box body assembly, as well as a hydrostatic stepless speed variator mounted outside the box body assembly, wherein the hydrostatic stepless speed variator enables the steering angle of the caterpillar equipment and the rotation amplitude of a steering wheel to be in proportional relation through adjusting the rotational speed of an outer gear ring of the proportional steering mechanism, so that the steering accuracy and stability of the caterpillar equipment can be improved. However, by virtue of a chute-type gearshift mechanism and a hydraulic control clutch, the gearshift process is effectively simplified, and a clutch operation function is integrated, so that clutch-operation-free gearshift is realized, and the clutch-operation-free gearshift transmission is suitable for the field of agricultural caterpillar equipment with stable working conditions.

Description

technical field [0001] The invention relates to the technical field of power transmission of crawler equipment, in particular to an operation-free clutch-shift transmission for crawler equipment. Background technique [0002] Tracked equipment mainly includes tracked construction machinery, tracked military machinery, and tracked agricultural machinery. Among them, when tracked agricultural machinery is working in the field, its working conditions are usually very stable, and there is no need to frequently switch gears, and even the throttle is not used. There is no need to adjust in time (usually a hand throttle is installed). For example, when a crawler tractor is performing rotary tillage operations, it generally works in a certain constant gear, and the working conditions are adjusted through the hand throttle, so there is no need to frequently switch gears during operation; however, since the driver who operates the crawler agricultural machinery usually has no car driv...
