Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. see figure 1 , figure 2 with image 3 , two symmetrical lateral stabilizers 3 are installed between the vehicle frame 1 and the unsprung part 2. The structure of the lateral stabilizer is: the cylinder 4 is cylindrical and adopts a casting machining structure. The external dimensions of the cylinder 4 and the internal structure size can be obtained from the actual tonnage and installation space of the vehicle; the rod barrel 5 is cylindrical and adopts a casting machining structure, and the structure and quantity arrangement of the seal ring 6 at the head of the rod barrel can be calculated according to the actual tonnage of the vehicle. Design, the structural size of the rod barrel can be obtained according to the structural size of the cylinder barrel and the actual installation space; the floating piston 7 is cylindrical and adopts a castin...

Abstract

The invention discloses a transverse stabilizing device with the transverse stable stiffness changing along with a roll angle in the wheel hopping process. The device aims to solve the problems that when the traditional transverse stabilizing device is suspended and hops, a geometric structure affects suspension and hopping, and the operation stability is poor. The transverse stabilizing device comprises a cylinder barrel (4) and a rod barrel (5) which are mutually sleeved together, wherein the cylinder barrel (4) is connected with a vehicle frame (1) through a spherical joint bearing (9); and the rod barrel (5) is connected with a lower spring part (2) through the spherical joint bearing (9). The transverse stabilizing device has the benefits that the cylinder barrel (4) and the rod barrel (5) can perform relative displacement in the wheel hopping process to drive a floating piston (7) to perform relative displacement, so as to lead to the compression and the stretching of gas in the cylinder barrel (4) and the rod barrel (5); when the rolling amplitude is larger, the rolling stiffness of the transverse stabilizing device is increased to ensure a smaller roll angle; when the rolling amplitude is smaller, the rolling stiffness of the transverse stabilizing device is reduced to ensure the adhesion of a tire onto the ground, so that the vehicle has good rideability; and the transverse stable stiffness of the transverse stabilizing device can also be adjusted through adjusting the pressure intensity of filled gas.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, in particular to a lateral stabilizing device for automobiles. Background technique [0002] Now the commonly used stabilizer bars on dump trucks are rigid rods, one side is connected to the frame through a joint bearing, and the other side is connected to the unsprung part through a joint bearing. This structure causes the vehicle to move when the suspension jumps up and down. Determined by the geometry, resulting in an asymmetric motion of the vehicle. More importantly, the stiffness of rigid rods is constant. If the stiffness is small, the vehicle’s anti-rolling ability will be low, and the rods will be easily deformed, posing a safety hazard. Insufficient grip and abnormal wear of the tires make the handling of the vehicle poor. Contents of the invention [0003] The object of the present invention is to propose a lateral stabilizing device whose lateral stabilizing stiffness chang...
