Problems solved by technology

[0012]However, the conventional lower arm cannot limit the installation direction of the vertical bushing (30), even if the type of vehicle or suspension system is the same, it is installed at the vertical connection end (13 ) of the vertical bushing (30) will also be oriented differently depending on the operating environment, resulting in a problem with spring characteristics that vary from vehicle to vehicle
[0013] When inserting the vertical bushing (30) into the bushing hole (17) of the vertical connection end (13) for installation, in order to control the direction of the vertical bushing (30) , the direction can be controlled by the clamp, and the vertical bushing (30) is installed, which leads to an increase in cost

Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0027] like Figure 4 , Figure 5 As shown, the lower arm 10 includes three ends: a horizontal connecting end 11 , a vertical connecting end 13 and a ball joint end 15 . Horizontal bushing 20 (also known as 'A bushing') is installed in the horizontal connection end 11, and it is connected with the bracket 1 (such as figure 1 shown) for connection; vertical bushing 30 (also known as 'geometric bushing' or 'G bushing') is installed in vertical connection end 13, which also connects with bracket 1; ball joint 40 is installed in ball joint end 15, it is connected with the steering knuckle of the wheel.

[0028] The above-mentioned vertica...

Abstract

The invention relates to a vehicle lower arm. A vertical linear is inserted into a linear hole at the vertical connection end of the lower arm to mount, a projection rib formed on an outer tube is rightly mounted in a fixation groove formed on the linear hole. Combining the character of a pre-determined lower arm spring based on the vehicle model or kind of a suspension system, while mounting, the direction of the vertical linear is automatically limited, thus the character of the lower arm spring is always kept constant for the vehicle model or same vehicle model with same kind of suspensionsystem. In addition, while mounting, it is not necessary to independently use a clamper and the vertical linear is also easily mounted, therefore the cost is saved, the assembling time is shortened and the production is also increased.

Description

technical field [0001] The present invention relates to a lower arm of an automobile. When a vertical bush is mounted on the lower arm, the assembly direction of the vertical bush can be restricted depending on the vehicle type or the type of suspension system. Background technique [0002] Car suspension system (suspension) is a device that can improve ride comfort and driving stability. Its main function is to ease the impact of uneven road surfaces on the frame. [0003] There is a lower arm (10) that is used to connect the vehicle body and the wheel in the above-mentioned suspension system, and the lower arm (10) has the function of supporting, and it includes three ends, such as figure 1 shown. [0004] That is, the lower arm (10) includes three ends: a horizontal connection end (11), a vertical connection end (13) and a ball joint end (15). Horizontal bushing 20 (also known as "A bushing") is installed in the horizontal connection end (11), which is connected to the ...
