Novel power matching system of energy-saving road roller

Abstract

The invention relates to a novel power matching system for an energy-saving road roller. The novel power matching system comprises a controller, an electric control diesel engine, a diesel engine rotary speed sensor, a travelling speed control handle, a travelling pump variable electric proportional coil, a travelling motor variable electric proportional coil, a travelling pump pressure sensor, atravelling motor rotary speed sensor, a vibration frequency control knob, a vibration pump variable electric proportional coil, a vibration motor variable electric proportional coil, a vibration pumppressure sensor and a vibration motor rotary speed sensor; and the speed of a whole machine can be automatically adjusted through monitoring operation states of the diesel engine, pumps and motors inthe road roller in real time, so that the total efficiency and energy consumption ratio of the diesel engine, the pumps and the motors are the highest. By adopting the power matching system provided by the invention, instant power generated in a travelling or vibration process of the road roller can be effectively inhibited; meanwhile, the power consumption and noise also can be effectively reduced and the utilization cost is saved.

Description

technical field [0001] The invention belongs to the technical field of road surface construction machinery, and in particular relates to a novel energy-saving road roller power matching system. Background technique [0002] At present, the road machinery industry, such as road rollers, pavers, and milling machines, are all fixed-speed mechanical equipment. Taking the road roller as an example, because of the large walking and vibration inertia, the power required for starting and stopping during the walking or vibration process is relatively large, and when the walking speed or frequency reaches a constant value, the load of the diesel engine is only about 60%, so Starting and stopping the diesel engine without the whole vehicle has high energy consumption and noise, and has no benefit to the construction performance of the whole vehicle, resulting in waste of resources and uncomfortable driving. Contents of the invention [0003] The purpose of the present invention is t...
