Abstract

The invention relates to the field of engineering machinery, in particular to a single-motor double-shaft-output electrically-driven crawler-type bulldozer which is composed of a main frame, an engine system, a transfer case, an elastic coupling, an alternating-current power generator connecting disc, an alternating-current power generator, an electrically-driven controller, an alternating-current double-shaft-output driving motor, a rear axle shell, a steering clutch and brake, an end transmission system, a hydraulic system, an electrically-driven cooling system, a crawler traveling system, a cab, a control system and a working device. An electrically-driven system is utilized to replace parts like a clutch, a transmission, a hydraulic torque converter, a universal spindle coupling, a transmission shaft and a rear axle differential which are in mechanical transmission, so that the bulldozer is small in maintenance quantity. In addition, the bulldozer is high in traction performance due to electric drive, capable of realizing stepless speed adjusting, stable in running, safe and reliable in traveling and good in economic effect.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an electrically driven crawler bulldozer with single-motor and two-shaft outputs. Background technique [0002] At present, most of the medium and high-power crawler bulldozers at home and abroad adopt hydraulic-mechanical transmission. Hydraulic-mechanical transmission bulldozers include hydraulic torque converters, coupling assemblies, planetary gear power shift transmissions, central transmission systems, steering clutches and steering brakes, final drives and travel systems, etc. However, due to hydraulic- Mechanically driven bulldozers have high transmission efficiency, high noise, high fuel consumption, frequent driver manipulation and high labor intensity during work. Therefore, they cannot meet the requirements of social and economic development. Contents of the invention [0003] In order to solve the above problems, the present invention provides an electric driv...
