Abstract

The invention discloses a static pressure transmission system of an eight-wheel vehicle. The static pressure transmission system of the eight-wheel vehicle comprises a stepless speed regulating system, a static pressure transmission synchronous drive system, a static pressure transmission time-share drive system and a brake system. The stepless speed regulating system comprises a main oil way driven by a duplex plunger variable pump, a control oil way driven by an oil compensation pump, a controller and a sensor. The static pressure transmission synchronous drive system comprises a left side splitter and a right side splitter, wherein the left side splitter and the right side splitter are connected with the duplex plunger variable pump. The static pressure transmission time-share drive system comprises a drive switch valve, an oil controlled valve and a cartridge valve. The brake system comprises hydraulic brakes integrated on motors at the two ends. Through the fact that the stepless speed regulating system, the time-share drive system, the synchronous control system and the parking brake system are designed, the static pressure transmission system of the eight-wheel vehicle effectively solves the problems of synchronous control, power matching and stepless speed regulating in the application of the static pressure technology in transmission systems of vehicles.

Description

technical field [0001] The invention belongs to the technical field of vehicle static pressure transmission, and relates to a static pressure transmission system of an eight-wheel vehicle. Background technique [0002] The drive transmission system of existing engineering vehicles mainly includes three types: gear transmission, hydraulic torque conversion transmission and static pressure transmission. Gear transmission has the advantages of simple structure, low cost and high transmission efficiency, but it can only complete step speed regulation, which has the problems of high noise and poor transmission stability; the hydraulic torque converter transmission system has stable and low noise, and can realize stepless The advantage of variable speed, but the transmission efficiency is low. Hydrostatic transmission has the advantages of light weight, compact structure, easy layout, simple control, and stable operation. It can better meet harsh working conditions such as load, ...
