Problems solved by technology

The pure electric drive crawler chassis generally adopts the solution of battery pack plus motor, which has the advantages of fast start, fast response and wide speed regulation range, etc., but at the same time, it also has shortcomings such as insufficient power, short standby time, and long charging time. In the complex terrain environment, pure electric drive still faces the problem of being unable to get out of trouble; pure hydraulic drive usually has a scheme of engine plus hydraulic pump, hydraulic circuit and hydraulic motor. Although this scheme has sufficient power, it has a small speed range and slow response. There is a large amount of flow and pressure loss, resulting in huge energy loss, and at the same time, a large amount of hydraulic energy loss and high-pressure hydraulic environment lead to loss of hydraulic components

Abstract

The invention discloses a novel electro-hydraulic hybrid drive crawler-type chassis, relates to the field of crawler-type chassis, and aims to solve the problems that in the prior art, the speed regulation range is small, the response is slow, the energy loss is large, and the service life of a hydraulic system is shortened. The advantages of fast speed regulation response and sufficient power are taken into consideration, stable walking under complex road conditions is achieved, energy conservation and emission reduction are achieved, electric energy of an electric drive system is provided by a generator, compared with traditional single electric drive, long-time charging is not needed, long-distance work can be achieved, the system pressure of a hydraulic system during work is reduced through power distribution design, and the service life of the hydraulic system is prolonged. The service life of the hydraulic system is greatly prolonged, the hydraulic system adopts a variable pump and closed loop integrated cooling system, overflow loss and throttling loss are reduced, the utilization rate of energy is increased, and the purposes of environmental protection and energy conservation are achieved.

Description

technical field [0001] The invention relates to the field of crawler type chassis, in particular to a novel hydraulic-electric hybrid drive crawler type chassis. Background technique [0002] With the progress of science and technology and the development of the times, the concept of energy saving and emission reduction has been deeply rooted in the hearts of the people, and the current concept of "green environmental protection" has penetrated into all aspects of social life. In recent years, the absolute status of traditional fuel technology has been impacted. Hybrid technology and pure electric technology have emerged. Products with low fuel consumption or even no fuel consumption have gradually increased their market share. More and more industries are also favoring this kind of environmental protection. technology. [0003] As a large agricultural country, my country is striving to develop towards the goal of becoming a powerful agricultural country. Agricultural mech...
