Abstract

The invention provides an independent hydraulic drive system of an automobile. The independent hydraulic drive system of the automobile comprises a power system, an energy storage system, an actuating mechanism, a brake system and a control system. The power system comprises an engine, a clutch connected with the engine, and a motor connected with the clutch. The energy storage system comprises a storage battery pack and an energy accumulator, and the storage battery pack can be used for driving the motor to rotate. The actuating mechanism comprises a variable pump capable of being driven by the motor, and the variable pump drives another motor to rotate so that wheels can be driven to rotate. The brake system comprises a brake valve set and brakes coaxial with the wheels. The control system comprises a controller, a rotation speed sensor, a steering sensor, a pressure sensor, a gear shift switch and a brake pedal. The controller can control the engine to output kinetic energy to the outside, or control the engine to stop and make the storage battery drive the motor to rotate so that kinetic energy can be output to the outside. The independent hydraulic drive system of the automobile can achieve infrared silence of the automobile, automobile speed regulation in an ultra-large range, automatic gear shifting and energy recycling.

Description

technical field [0001] The invention relates to a hydraulic independent drive system, in particular to a hydraulic independent drive system for vehicles. Background technique [0002] Multi-wheel independent drive is widely used in the field of automobiles and robots, such as construction machinery, tanks, off-road vehicles, fire robots, explosion-proof robots, etc. According to literature review, vehicle independent drive system mainly includes pure electric drive and hydrostatic drive in terms of principle and structure. Among them, pure electric drive is mainly used in light and small vehicles traveling at high speed due to the characteristics of high wheel integration, difficult maintenance, and low power. Hydrostatic drive will be widely used in the future automotive field due to its small structure, wide speed range, convenient electronic control, and easy realization of constant torque or constant power adjustment. [0003] There are some relevant disclosures in the...
