Abstract

The invention relates to the technical field of engineering machines, and discloses a hydraulic driving system, a base plate and a mechanical traveling device. The hydraulic driving system comprises a multi-power system, a power composite oil path and traveling units, wherein the multi-power system comprises a plurality of power sources and a driving oil pump group which is connected with each power source, and the driving oil pump groups are used for converting power provided by a power system into hydraulic driving force; the power composite oil path is used for compounding the hydraulic driving force of the driving oil pump groups which are connected with the power sources to a main oil path; and the traveling units are connected with the power composite oil path and are driven to travel by the hydraulic driving force. According to the hydraulic driving system, power of the multi-power system is converted into the hydraulic driving force, and each traveling unit is driven to move by utilizing the hydraulic driving force, so that each traveling unit can be driven to travel; and the integral driving system is stable in motion, simple in layout of an integral pipeline and convenient to operate, and infinitely variable speed is realized.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hydraulic drive system, a chassis installed with the hydraulic drive system and a mechanical traveling device with the chassis. Background technique [0002] At present, many mechanical traveling devices are mechanically driven by engines, and the engines and their mechanical driving devices are arranged on the chassis of the mechanical traveling devices. [0003] At present, most of the chassis of large-tonnage special-purpose engineering vehicles produced by domestic and foreign automobile companies use a single engine as the power source, and the transmission system adopts mechanical transmission. [0004] A single engine is used as the power source, and the mechanically driven chassis will be driven by multi-stage gears and shifting mechanisms, which will make the chassis with the transmission system heavy, and the braking and steering control systems will be...
