Example Embodiment

[0033] Such as Figure 1-4 Shown is an embodiment of a vehicle with a stabilizer bar driving device in the present invention: the vehicle includes a body and a suspension 9, and the suspension 9 is provided with a suspension corresponding to the four wheels of the front, rear, left, and right. 9 is connected to the stabilizer bar 6, the stabilizer bar 6 is U-shaped, arranged horizontally between the wheels on both sides, and the stabilizer bar hanger 7 is connected to the stabilizer bar 6 to push the stabilizer bar 6 to move. A reversing arm 5 is hinged on the other side of the stabilizer bar. The reversing arm 5 is V-shaped, which can change the transmission direction. The reversing arm 5 and the stabilizer rod 7 form a transmission assembly. The reversing arm 5 passes The bearing is rotatably assembled on the suspension 9, and the other end of the reversing arm 5 is connected with a hydraulic cylinder 3 that drives the stabilizer bar 6 to rotate, and the piston rod 8 of the h...

Abstract

The invention relates to the technical field of vehicle safety and provides a vehicle roll control method, a vehicle and a driving device of a stabilizer bar. The vehicle comprises a vehicle body anda suspension, wherein the suspension is provided with a stabilizer bar and a driving device of the stabilizer bar to resist the rolling of the vehicle body. The driving device comprises a driving cylinder and transmission components connected with a piston rod in the driving cylinder. And the driving cylinder is provided with a limiting device that locks the piston rod in the driving cylinder. Thelimiting device with locking position of the piston rod is arranged in the drive cylinder, which can limit the travel of the piston rod and ensure that the piston rod is in a stable working range, thereby ensuring that the stabilizer rod can provide the vehicle body with anti-roll moment and protect the transmission structure from being destroyed. And the stability and safety of the work are guaranteed. The limiting device, which can lock position of the piston rod, increases anti-roll stiffness of the stabilizer bar.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a vehicle roll control method, a vehicle and a drive device for a stabilizer bar. Background technique [0002] Statistics show that rollover accidents account for more than 20% of the vehicle accidents causing casualties in Europe and North America. Rollover accidents only account for 8% to 12% of heavy truck accidents, but the losses caused account for about 60% of all heavy truck accident losses. Various automobile accident surveys show that in single-vehicle collision accidents of light vehicles, 54% of fatal accidents are related to rollover, and rollover accidents, especially those of large passenger cars, pose a serious threat to road traffic safety. In order to suppress the roll of the vehicle and improve the lateral stability of the vehicle, the stabilizer bar system has begun to receive attention and research. [0003] The Chinese utility model patent whose aut...
