Abstract

[Problem] To provide a vehicle suspension arm which can be produced at a low cost and in which the shape of each constituent component can be simplified and the size and weight of the constituent components can be logically reduced. [Solution] When forming the lower arm (2) of a vehicle suspension, an arm main body (10) is configured from a pair of opposing side plates (11), a bottom plate (12) integrally formed with both side plates (11) so as to connect same, and a spring receiving seat member (13) attached to the side plates (11), wherein both side plates (11) are disposed so as to extend within the bottom region (R) of the spring receiving seat member (13).

Description

technical field

[0001] The present invention relates to a suspension arm for a vehicle that simplifies the shapes of components and reasonably reduces the size of the overall structure. Background technique

[0002] There are various types of vehicle suspension arms. For example, there are suspension arms in which an upper arm is connected to the upper part of the steering knuckle on the shaft side, one end of the lower arm is connected to the lower part, and the other ends of these arms are connected to the vehicle body side. A suspension coil spring or a shock absorber (damper) is arranged between the vehicle body and the vehicle body.

[0003] The lower arm has a long arm main body, a connecting portion provided at an end of the arm main body, and a spring receiving member provided at a substantially central portion of the arm main body, and a suspension coil spring is provided on the spring receiving member. , install the lower end of the shock absorber near the knuckle...

Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0030] Such as figure 1 As shown, the suspension of this embodiment has an upper arm 1 and a lower arm 2 . One end of these arms 1 and 2 is connected to the vehicle body side B, and the other end is connected to a knuckle 3 on the shaft A side. In addition, reference sign "W" in a drawing is a wheel, and "4" is an axle.

[0031] Such as figure 1 , 2 As shown, the lower arm 2 has: a long arm body 10; a spring support member 13, which is arranged on the upper part of the arm body 10, and supports the suspension coil spring 8; a connecting part 6 and a connecting part 7, which are arranged on the arm body 10 The two ends of the shaft are connected to the side A of the shaft or the side B of the car body.

[0032] Such as figure 2 , 3 As shown, the arm body 10 is generally open upward and has a U-shaped cross section, and has a pair of facing side plates 11 and a bo...
