Problems solved by technology
[0004] However, the existing hydraulic active stabilizer bar system has the drawback that the front and rear stabilizer bar torques are the same or restrict each other, so that the vehicle cannot independently distribute the front and rear stabilizer bar torques during driving, especially in high-speed steering and uneven road conditions. There is room for improvement in terms of ride comfort and driving safety

The invention discloses a hydraulic system of active stabilizer bar based on independent binary channels. The hydraulic system includes a front axle oil hydraulic circuit (1) communicated with a front axle oil hydraulic cylinder (101) and a rear axle oil hydraulic circuit (2) communicated with a rear axle oil hydraulic cylinder (102); the front axle oil hydraulic circuit (1) is communicated with a fuel tank (12) through an oil pump (11); the rear axle oil hydraulic circuit (2) is also communicated with the fuel tank (12) through the oil pump (11). The hydraulic system of active stabilizer bar based on independent binary channels can independently assort the front and back stabilizer bar and improve the riding comfort and safety of vehicles.
Description
technical field [0001] The invention belongs to the technical field of automobile hydraulic systems, in particular to an active stabilizer bar hydraulic system based on independent dual channels that independently distributes front and rear stabilizer bar moments. Background technique [0002] The active stabilizer bar can adjust the size of the anti-rolling moment in real time, realize the dynamic change of the vehicle's roll stiffness, adjust the body posture in time during the driving process of the vehicle, and improve the comfort of the ride and the safety of the vehicle. [0003] At present, the common active stabilizer bars mainly include electric motor type and hydraulic type. Because the hydraulic transmission system has the advantages of small size and large output torque, hydraulic active stabilizer bars have been installed on some brands of cars. For example, some models of BMW and Land Rover have installed hydraulic active stabilizer bars. [0004] However, th...
