Stabilizer bar device of automobile

Abstract

The invention provides a stabilizer bar device of an automobile, and belongs to the technical field of automobiles. The stabilizer bar device solves the problems that an existing stabilizer bar device of the automobile is low in transmission efficiency and high in energy loss. The stabilizer bar device comprises a stabilizer bar body, a stabilizer bar support and a stabilizer bar lining, the stabilizer bar body is installed on an auxiliary frame through the stabilizer bar lining and the stabilizer bar support, the stabilizer bar body is a straight bar, the two ends of the stabilizer bar body directly face lower swing arm assemblies at the two ends of the auxiliary frame in position, bevel gears I are arranged at the two ends of the stabilizer bar body, the bevel gears I and the stabilizer bar body are positioned axially and circumferentially, the positions, corresponding to the two ends of the stabilizer bar body, of the lower swing arm assemblies are provided with connecting sleeves, the connecting sleeves are horizontally arranged and are perpendicular to the stabilizer bar body, each connecting sleeve is provided with a bevel gear II capable of being meshed with the bevel gear I at the corresponding position, and the bevel gears II and the connecting sleeves are positioned axially and circumferentially. The stabilizer bar device of the automobile is high in force transmission efficiency and good in balancing performance.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a stabilizer bar device for automobiles. Background technique [0002] The car stabilizer bar device is set between the sub-frame and the suspension of the car to balance the car body and prevent the car body from excessive lateral roll when turning. like figure 1 As shown, the common automobile stabilizer bar device uses the stabilizer bar connecting rod 4 to connect the stabilizer bar body 1 with the strut assembly. The stabilizer bar bushing 2 and the stabilizer bar bracket 3 are installed on the subframe. [0003] The shape of the existing stabilizer bar body is "U" shape, for example, a kind of car suspension stabilizer bar structure disclosed in Chinese patent [Patent No. Symmetrical curved shape, the end of which is provided with a stabilizer bar joint, the middle section is the middle straight part of the stabilizer bar, through which the middle straight part of the s...

AI Technical Summary

Problems solved by technology

[0004] The structure of the above-mentioned stabilizer bar has a curved part, and parts around the wheel end need to be avoided, resulting in a complex structure of the stabilizer bar body and increased production costs

There is a force arm in the curved part of the stabilizer bar body (for example, the attached figure 1 L in the middle), in the force transmission process generated by the wheel jump, the force transmission efficiency is reduced due to the principle of leverage; and the stabilizer bar body may be bent and deformed due to the force of the curved part, resulting in energy loss. These problems will affect the stabilizer bar Negatively affected by the balance effect of the device
