Caterpillar band equipment transmission suitable for remote control of gear shifting

Abstract

A caterpillar band equipment transmission suitable for remote control of gear shifting comprises a main transmission assembly, an auxiliary transmission assembly, a proportional steering mechanism, a main speed reducing assembly, a power output transmission assembly, a remote gear shifting assembly and a static hydraulic stepless speed change device. The main transmission assembly, the auxiliary transmission assembly, the proportional steering mechanism, the main speed reducing assembly, the power output transmission assembly and the remote gear shifting assembly are mounted in a box assembly, and the static hydraulic stepless speed change device is mounted outside the box assembly. Power is input through the main transmission assembly, one part of the power is transmitted to the power output transmission assembly and used for driving an external power device, and the other part of the power is transmitted to the proportional steering mechanism through the auxiliary transmission assembly, then transmitted to the main speed reducing assembly after a proportional relation is formed through the combination of the static hydraulic stepless speed change device and the proportional steering mechanism and output to a driving axle to drive caterpillar band equipment to run. Meanwhile, the rotating speed of an outer gear ring of the proportional steering mechanism is adjusted through the static hydraulic stepless speed change device, the steering angle of the caterpillar band equipment and the rotating amplitude of a steering disc form a certain proportional relation, and therefore the steering accuracy and operation stability of the caterpillar band equipment are improved. The remote gear shifting assembly is used for achieving electronic control and remote gear shifting.

Description

technical field [0001] The invention relates to the technical field of crawler equipment power transmission, in particular to a transmission for crawler equipment suitable for remote control of shifting. Background technique [0002] Tracked equipment vehicles (tracked tractors, tracked rotary tillers, tracked combine harvesters, etc.) used in the agricultural field, because these tracked equipment are mainly used for field operations, they rarely drive on the road. When crawler agricultural machinery is working in the field, its working condition is usually very stable, there is no need to switch gears frequently, and even the throttle does not need to be adjusted in time (usually equipped with a hand throttle); Constant gear work, adjust the working conditions through the hand accelerator, do not need to frequently switch gears during operation, but because the driver who operates the crawler agricultural machinery usually has no car driving experience, and is not familiar...
