Abstract

The invention discloses a chassis hydraulic drive system which comprises an engine and a hydraulic oil tank. The engine is connected with a variable pump through a coupling. The variable pump is connected with an oil supplementing pump and a gear pump in series and is connected with a controller. The controller is provided with an accelerator pedal and a brake pedal. The variable pump is connected with a drive axle. A hydraulic motor is embedded into the drive axle. The drive axle and the hydraulic motor are integrated, the space utilization rate is high, and maintenance of the hydraulic motor is convenient; meanwhile, a chassis is driven hydraulically, the system is safe, reliable, rapid and convenient to use, and the working efficiency is improved to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of hydraulic drive, in particular to a chassis hydraulic drive system. Background technique [0002] At present, for the replacement of external weapons of fighter jets, there is a special special vehicle for replacement. Its main function is to complete the lifting and replacement of external weapons after positioning. and positioning functions, the special vehicles used today cannot meet the requirements, which is mainly reflected in the difficulty of speed control during autonomous walking. , and travel at a stable speed of no more than 3Km / h (including forward and backward), and also meet the lifting requirements, so the existing special vehicles cannot meet the requirements for use. Contents of the invention [0003] The purpose of the present invention is to provide a chassis hydraulic drive system to solve the problem that the amount of special vehicles used for the positioning and replacement of t...
