Power reversing control system

Abstract

The invention discloses a power reversing control system. The power reversing control system comprises a hollow telescopic cylinder type independent motion combined oil cylinder, a multifunctional manual-electric integrated rotary control valve, a clutch pedal, an electric appliance wiring harness, an intermediate relay, a hydraulic source supply system, a filtering device and an enclosure auxiliary part. As for an electro-hydraulic control reversing system for a tractor, numerous complicated operation actions of an operator in the reversing process are carried out in an electro-hydraulic modethrough program calculation and control, so that high sensitivity is achieved, reversing is quick and stable, the system replaces a driver for operation, and the problems of mechanical failures and low efficiency caused by poor coordination, improper operation, misoperation and the like are solved. A control means is provided for intelligent machines through combined usage of mechanical, electricand hydraulic modes, the defect that a current manual operation structure cannot achieve electric control or man-machine combination is overcome, and the remarkable characteristic of the power reversing control system is that the tractor can be upgraded and updated with small cost, and accordingly social resources are obviously saved.

Description

technical field [0001] The invention relates to the technical field of tractor power, in particular to a power reversing control system. Background technique [0002] my country is a large agricultural country with complex farmland. When tractors are operating in the field, they are constrained by the area, geographical shape, and state of the field. Especially when working in the farmland, the tractor turns around frequently. It needs to retreat in time and quickly when it is moving forward. At present, tractors are manually operated. The direction is difficult, the movement is slow, the operation is complicated, and the reversing gear is often damaged due to poor operation coordination. When the tractor switches from forward to reverse, it needs to step on the clutch, brake, reduce the speed to near zero, change gears, release the clutch, release the brake, and increase the accelerator. A series of actions, if electro-hydraulic instead of manual operation, will liberate dri...

Problems solved by technology

[0003] The present invention is dedicated to solving the execution part of gear shifting. Tractors in my country generally use mechanical gear shifting mechanisms. If foreign power shifting structures are adopted, the traditional tractor structure will lose its original characteristics, and high-priced tractors will bring great benefits to the national economy. The focus of our research is how to use the comprehensive characteristics of machinery, electricity, and hydraulics to control traditional tractors, and give full play to the effective strengths and complementary shortcomings of machinery, electricity, and hydraulics.
