Description

TECHNICAL FIELD

[0001] The utility model relates to a house car technical field especially relates to a house car prevents rocking torsion beam axle structure. BACKGROUND

[0002] With the improvement of people's living standards and the increase of travel experience requirements, the house car market is expanding, and the house car is easily affected by side wind, uneven road surface and vehicle driving state change and other factors to produce rocking due to its own high gravity center and large vehicle body size during driving;

[0003] The torsion beam axle system of the current trailer house car is fixed by extrusion of the core shaft, rubber rod and outer sleeve tube, and when the trailer house car load changes or the vehicle body jumps, rotation extrusion rubber is generated to start the damping effect. Because the rubber is a soft connection, the wheel not only jumps in the Z direction, but also swings in the X and Y directions, which can cause the vehicle body to be unstable and the tire to be unevenly worn. Because the core shaft is only fixed by extrusion of the rubber, the core shaft can be loose and come out when the rubber fails and ages, which can cause travel safety hazards and other problems. UTILITY MODEL CONTENTS

[0006] Furthermore, a through-type fixing hole is symmetrically arranged below the outer side wall of the swing arm.

[0007] Furthermore, an outer sleeve tube is arranged on the outer side of the core shaft, and the outer sleeve tube is fixedly connected with the bearing flange seat.

[0008] Furthermore, a bearing seat is arranged on the outer side of the bearing body on the right side of the core shaft.

[0009] Beneficial effects: the core shaft in the utility model adopts four rubber bars covered by four arc grooves, is uniformly stressed, bears better, has longer service life, the core shaft adopts solid core shaft and has stronger rigidity, the both ends of the core shaft adopt deep groove ball bearings to better support left and right, ensure that the core shaft will not produce displacement in X, Y, Z directions, ensure that the wheel will not be deflected, solve the "eight" type problem caused by tire eccentric wear, make the vehicle travel more stable and safe, reduce the possibility of death swing, at the same time, the bearing body adopts bearing flange seat, so that the device is convenient to install, compact structure, convenient structure, small occupied space, low energy consumption and low cost of single machine.
