Vehicle and its lateral stabilizer

Abstract

A vehicle and a transversely-stabilizing device thereof. The transversely-stabilizing device comprises a front transversely-stabilizing rod (4) and a rear transversely-stabilizing rod (16), and further comprises a first hydraulic cylinder (1), a second hydraulic cylinder (5), a third hydraulic cylinder (9) and a fourth hydraulic cylinder (8). The first hydraulic cylinder (1) and the second hydraulic cylinder (5) are in transmission connection to the left end and the right end of the front transversely-stabilizing rod (4). The third hydraulic cylinder (9) and the fourth hydraulic cylinder (8) are separately in transmission connection to the left end and the right end of the rear transversely-stabilizing rod (16). A rod port of the first hydraulic cylinder (1) is connected to a head port of the fourth hydraulic cylinder (8) through a first channel (11). A head port of the first hydraulic cylinder (1) is connected to a rod port of the fourth hydraulic cylinder (8) through a second oil channel (12). A rod port of the second hydraulic cylinder (5) is connected to a head port of the third hydraulic cylinder (9) through a third oil channel (13). A head port of the second hydraulic cylinder (5) is connected to a rod port of the third hydraulic cylinder (9) through a fourth oil channel (14). An energy accumulator is disposed on each oil channel. The transversely-stabilizing device and the vehicle that uses the transversely-stabilizing device can reduce vehicle roll angle vibration when the vehicle has a relatively small roll angle.

Description

technical field [0001] The invention relates to a vehicle and a lateral stabilizing device thereof. Background technique [0002] Existing vehicles include car body, vehicle axle and front and rear stabilizer bars, and the two ends of the stabilizer bars are hingedly connected with the left and right sides of the car body respectively. Rolling occurs, and the rolling of the vehicle body causes the anti-rolling stiffness of the axle to be twisted, thereby reducing the rolling of the vehicle body. However, during the running of the vehicle, when the vehicle body produces a small roll angle (such as driving at a high speed on a gravel road with small protrusions), at this time, it is expected that the lateral stabilizer device can provide a small anti-roll stiffness, so as to Improve the ride comfort of the vehicle, and when the vehicle is driving on a slippery road, it can improve the grip performance of the vehicle, reduce tire sideslip, improve the handling stability and pa...

AI Technical Summary

Problems solved by technology

However, the torsional stiffness of the traditional stabilizer bar has little to do with the roll angle of the vehicle body. When the vehicle passes on an uneven road, because the stabilizer bar is directly connected to the vehicle body, even if the roll angle of the vehicle body is small, the stabilizer bar also provides a The larger anti-rolling moment causes the car to generate a larger roll angle vibration, which affects the ride comfort
