Problems solved by technology

Construction machinery driven by an internal combustion engine has problems such as high fuel consumption, waste discharge and environmental pollution; while construction machinery driven by a single electric power has poor maneuverability and cannot work without external power grid or power failure. However, the existing construction machinery technology with electromechanical and hydraulic drive functions adopts mechanical connection, which has high manufacturing cost, rapid temperature rise of hydraulic drive, and many faults. Limited by the length of the cable, there are also shortcomings such as small operating range and inconvenient movement.

Abstract

The invention relates to a driving system for a tandem double-dynamic engineering machine. An engineering machine running by adopting single-dynamic drive has the problems that the oil consumption cost is high, the environment polluted by waste discharge, and the flexibility is poor, and has no external public supply network or cannot work under power cut, and as an adopted connection mode is a mechanical connection mode, the traditional engineering machine technology with an electromechanical dual-hydraulic drive function has the problems that the manufacturing cost is high, temperature rise is fast by adopting hydraulic drive and faults are multiple, and meanwhile, as the power supply mode of the engineering machine is of a towing type, the engineering machine is limited by cable length, and has the defects of being wide in working range and inconvenient to move. In order to overcome the problems and the defects, the invention provides the driving system for the tandem double-dynamic engineering machine, which is used for driving the engineering machine to run. The technical scheme adopted by the invention is that the lower bodywork of the engineering machine is provided with an engine (1); the output end of the engine (1) is provided with a clutch (2); the output end of the clutch (2) is connected with a motor (3); the output end of the motor (3) is provided with an oil pump (4); the output end of the oil pump (4) is connected with a working device (5), and therefore, the goal that the tandem double-dynamic engineering machine is driven to work can be achieved.

Description

technical field [0001] The invention relates to a serial dual-power construction machinery driving system. Background technique [0002] At present, the driving force of known construction machinery is an internal combustion engine or an electric motor. Construction machinery driven by an internal combustion engine has problems such as high fuel consumption and environmental pollution; while construction machinery driven by a single electric power has poor maneuverability and cannot work without external power grid or power failure. However, the existing construction machinery technology with electromechanical and hydraulic drive functions adopts mechanical connection, which has high manufacturing cost, rapid temperature rise of hydraulic drive, and many faults. Limited by the length of the cable, there are also shortcomings such as small operating range and inconvenient movement. Contents of the invention [0003] In order to overcome the above-mentioned problems existi...
