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.
