Lateral stabilizer and vehicle using the same

Abstract

The present invention relates to a transversely-stabilizing device and a vehicle using the transversely-stabilizing device. The transversely-stabilizing device comprises a transversely-stabilizing rod, a left hydraulic cylinder and a right hydraulic cylinder. A piston rod of the left hydraulic cylinder is in transmission connection to the left end of the transversely-stabilizing rod, and a piston rod of the right hydraulic cylinder is in transmission connection to the right end of the transversely-stabilizing rod. A rod port of the right hydraulic cylinder is connected to a head port of the left hydraulic cylinder through a first oil channel, and a head port of the right hydraulic cylinder is connected to a rod port of the left hydraulic cylinder through a second oil channel. A first energy accumulator is disposed on the first oil channel, and a second energy accumulator is disposed on the second oil channel. The present invention provides the transversely-stabilizing device which can reduce vehicle roll angle vibration when the vehicle has a relatively small roll angle and provides the vehicle that uses the transversely-stabilizing device.

Description

technical field [0001] The invention relates to a lateral stabilizing device and a vehicle using the same. Background technique [0002] Existing vehicle comprises car body, vehicle axle and the stabilizer bar that is arranged between car body and vehicle axle, and the two ends of stabilizer bar are hingedly connected with the left and right sides of car body respectively, when vehicle walks on uneven road Or when it is necessary to turn, the vehicle body will roll, and the roll of the vehicle body will cause the anti-rolling stiffness of the axle to be twisted, thereby reducing the roll 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 ro...

Problems solved by technology

However, the torsional stiffness of the traditional stabilizer bar has little to do with the inclination 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 large The anti-rolling moment makes the car produce a large roll angle vibration, which affects the ride comfort
