Problems solved by technology

Excavators driven by internal combustion engines have problems such as high fuel consumption and environmental pollution; while excavators driven by a single electric power have poor maneuverability and cannot work without external power grids or power outages. However, the existing excavator technology with electromechanical and hydraulic drive functions has high manufacturing cost, rapid temperature rise of hydraulic drive, and many faults. The operating range is small, and the movement is inconvenient, etc.

Abstract

The invention relates to a hybrid excavator provided with a transfer case mechanism. In order to solve the problem that a single-power excavator has high oil consumption cost, causes environmental pollution because of waste discharge, has poor maneuvering flexibility and cannot run without a power grid, the invention provides a hybrid driving device to drive the excavator to run. The invention adopts a technical scheme that: an engine (1) and a motor (2) are arranged on the excavator, wherein an interlocking device (3) is arranged at the output end of the engine (1); an interlocking clutch (4) is arranged at the output end of the motor (2); both the interlocking device (3) and the interlocking clutch (4) are connected with a transfer case (6); a gear clutch yoke (5) capable of inputting power of the engine (1) and the motor (2) into a hybrid excavator body respectively is arranged on the transfer case (6); an oil pump (7) is arranged at the output end of the transfer case (6); and the output end of the oil pump (7) is connected with a hydraulic system (8).

Description

technical field [0001] The invention relates to a hybrid excavator equipped with a transfer case mechanism. Background technique [0002] At present, the driving force of known excavators is an internal combustion engine or an electric motor, respectively. Excavators driven by internal combustion engines have problems such as high fuel consumption and environmental pollution; while excavators driven by a single electric power have poor maneuverability and cannot work without external power grids or power outages. However, the existing excavator technology with electromechanical and hydraulic drive functions has high manufacturing cost, rapid temperature rise of hydraulic drive, and many faults. The operating range is small, and the movement is inconvenient. Contents of the invention [0003] In order to overcome the above-mentioned problems existing in the existing excavator technology, the present invention provides a hybrid driving device to drive the excavator to run,...
