Problems solved by technology

However, the torsional stiffness of the traditional stabilizer bar has little to do with the roll angle of the car body. When the car passes through an uneven road, because the stabilizer bar is directly connected to the frame, even if the roll angle of the car body is small, the stabilizer bar is still a significant factor for the vehicle. The body provides a large anti-rolling moment, which makes the car produce a large roll angle vibration, which affects the ride comfort

Embodiment Construction

[0022] An example of a car is Figure 1~5 Shown: including vehicle frame 1, vehicle axle 2 and the lateral stabilizing device arranged between the vehicle frame 1 and the vehicle axle 2, the lateral stabilizing device includes a lateral stabilizing bar 4-2 and buffer structures respectively arranged at both ends of the lateral stabilizing bar, The structures of each buffer structure are the same, and now only one of the buffer structures will be described in detail. The buffer structure includes a fixing piece arranged on the vehicle frame and a drive connection with the corresponding end of the stabilizer bar 4-2 through a linkage mechanism. The movable part applies force to the fixed part under the action of the horizontal stabilizer bar, and there is a movable gap between the fixed part and the movable part. Movable parts comprise the rocking arm 5 that axis of rotation extends along left-right direction, and rocking arm rotation is arranged on the rocking arm seat 6-1, and...

Abstract

The invention relates to an automobile and a turning-angle-related rigidity-variable transverse stabilizing device of the automobile. The transverse stabilizing device comprises a transverse stabilizing rod and buffering structures arranged at at least one end of the transverse stabilizing rod. Each buffering structure comprises a fixed piece used for being arranged on a corresponding automobile frame and a movable piece which is in transmission connection with the corresponding end of the transverse stabilizing rod and used for exerting force on the fixed piece under the effect of the transverse stabilizing rod, wherein a movable gap is reserved between the fixed piece and the movable piece or an elastic buffering piece is arranged between the fixed piece and the movable piece. By means of the turning-angle-related rigidity-variable transverse stabilizing device and the automobile with the turning-angle-related rigidity-variable transverse stabilizing device, roll angle vibration of the automobile can be reduced when the automobile frame generates the small roll angle.

Description

technical field [0001] The invention relates to an automobile and a lateral stabilizing device with variable stiffness related to its corner. Background technique [0002] Existing automobile comprises vehicle frame, vehicle axle, is provided with stabilizer bar on the vehicle axle, and the two ends of stabilizer bar are hingedly connected with the left and right sides of vehicle frame respectively, when automobile walks on uneven road or needs to turn, The frame will produce roll, and the roll of the frame will cause the anti-roll stiffness of the axle to be twisted, thereby reducing the roll of the frame. However, when the car is running, when the frame has a small roll angle (such as driving at a high speed on a gravel road with small protrusions), at this time, people expect the lateral stabilizer to provide a small anti-roll stiffness. To improve the ride comfort of the car, and when the car is driving on a slippery road, it can improve the grip performance of the car,...
