Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and specifically relates to an eccentric bushing front lower control arm. Background Art

[0002] In the latest national standard of our country, "Terms and Definitions for Automobiles and Trailers" (GB / T3730.1—2001), an automobile is defined as follows: a vehicle driven by power, with 4 or more wheels and non-rail-mounted, mainly used for: carrying passengers and / or goods; towing vehicles carrying passengers and / or goods; special purposes.

[0003] An automobile suspension is an elastic connecting component between the frame and the wheels. The suspension is one of the important components of modern automobiles, mainly composed of elastic elements, shock absorbers and guiding mechanisms. Its main functions are to transmit all forces and torques acting on the wheels and the frame, to relieve the impact transmitted from the road surface to the frame, to attenuate the vibration caused thereby, and to ensure the ride comfort and handling stability of the automobile. An automobile suspension control arm bushing is generally composed of an outer sleeve, rubber and an inner sleeve, and the automobile suspension control arm bushing is symmetrically designed with the axis as the center.

[0004] For the existing automobile control arms using the above-mentioned bushings, the amount of nose dive during braking is very large. Nose dive during braking refers to the phenomenon that the front of the vehicle sinks while the rear of the vehicle rises when the vehicle brakes. Nose dive during braking has a great impact on the handling stability, passability and comfort of the vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide an eccentric bushing front lower control arm to solve the problem that for the existing automobile control arms using the above-mentioned bushings, the amount of nose dive during braking is very large. Nose dive during braking refers to the phenomenon that the front of the vehicle sinks while the rear of the vehicle rises when the vehicle brakes. Nose dive during braking has a great impact on the handling stability, passability and comfort of the vehicle as mentioned in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: an eccentric bushing front lower control arm, including an inner sleeve, a rubber sleeve and an outer sleeve. The rubber sleeve is sleeved on the outer wall of the inner sleeve, and the outer sleeve is sleeved on the outer wall of the rubber sleeve. The inner sleeve includes a central axis, an upper shaft and a lower shaft. The upper shaft is fixed at the top of the central axis, and the lower shaft is fixed at the bottom of the central axis. A plurality of retaining plates are arranged at equal intervals in a ring shape at the bottom of the outer wall of the outer sleeve.

[0007] Preferably, the height of the inner sleeve is 60MM.

[0008] Preferably, the inner sleeve is a copper alloy inner sleeve or a stainless steel inner sleeve, and the outer sleeve is a copper alloy outer sleeve or a stainless steel outer sleeve.

[0009] Preferably, the center of the outer wall of the central axis is 3 MM above the center position of the inner cavity of the rubber sleeve.

[0010] Preferably, the height of the outer sleeve is 30 MM.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can reduce the vehicle braking dive amount, improve the handling stability performance, passability and comfort of the vehicle. The center position of the inner sleeve is 3 MM above the center position of the rubber sleeve. By the eccentric setting of the inner sleeve, the vehicle braking dive amount is reduced, and the handling stability performance, passability and comfort of the vehicle are improved.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] The present invention provides an eccentric bushing front lower swing arm, which can reduce the vehicle braking dive amount, improve the handling stability performance, passability and comfort of the vehicle. Please refer to Figure 1 , including an inner sleeve 100, a rubber sleeve 200 and an outer sleeve 300;

[0018] Please refer to Figure 1 and Figure 2 , the inner sleeve 100 has a central axis 110, an upper axis 120 and a lower axis 130. Specifically, the upper axis 120 is provided at the top of the central axis 110, the lower axis 130 is provided at the bottom of the central axis 110. The central axis 110, the upper axis 120 and the lower axis 130 are integrally processed. An installation hole is opened at the top of the upper axis 120, and the installation hole penetrates through the bottom of the central axis 110 and the lower axis 130. The inner sleeve 100 is made of copper alloy or stainless steel, and the height of the inner sleeve 100 is 60 MM;

[0019] Please refer to againFigure 1 The rubber sleeve 200 is covered on the outer wall of the inner sleeve 100. The central position of the inner sleeve 100 is 3 mm above the central position of the rubber sleeve 200. By the eccentric setting of the inner sleeve 100, the vehicle braking dive amount is reduced, and the handling stability, passability and comfort of the vehicle are improved.

[0020] Please refer to Figure 1 and Figure 3 , the outer sleeve 300 has a plurality of baffles 310. Specifically, the plurality of baffles 310 are evenly and equidistantly arranged at the bottom of the outer wall of the outer sleeve 300. After the baffles 310 on the outer wall of the outer sleeve 300 are punched out from the sheet material by a stamping process, the sheet material is then rolled into a tubular shape by a pipe rolling process. Through the rigid springback of the baffles 310, it is snapped into the vehicle body, and the outer sleeve 300 is fixedly installed in the vehicle body through a rigid connection, ensuring the firm installation of the bushing.

[0021] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
