Embodiment Construction

[0045] Below, refer to Figure 1 to Figure 6 , the suspension arm member S according to the embodiment of the present invention will be described.

[0046] also, figure 1 The shown suspension arm member S has its orientation changed depending on the installation state and installation position on the vehicle to be installed. Therefore, for the sake of convenience, on the suspension arm member S, the support rod 1 is arranged in the longitudinal direction, and the depth direction of the weight-reducing portion 10 formed on the support rod 1 is taken as the front-rear direction, and the support The short-side direction of the weight-reducing part 10 of the rod 1 will be described as the up-down direction, and the sides where the connecting parts 2 and 2 are disposed will be described as the left and right sides.

[0047]

[0048] First, before describing the suspension arm member S according to the embodiment of the present invention, a suspension (illustration omitted) appl...

Abstract

A suspension arm member includes a connecting portion configured to connect plural members of a suspension, and a support bar extending and provided with the connecting portion at each end. The support bar is made of a resin material and includes plural lightening hole portions each formed in a shape of a recessed portion. The lightening hole portions include plural front upper lightening hole portions (11) formed in a front upper portion of the support bar, plural front lower lightening hole portions formed in a front lower portion of the support bar, plural rear upper lightening hole portions formed in a rear upper portion of the support bar, and plural rear lower lightening hole portions formed in a rear lower portion of the support bar.

Description

technical field [0001] The present invention relates to a suspension arm member for connecting a plurality of components in a suspension mounted on a vehicle. Background technique [0002] Conventionally, in a suspension mounted on a vehicle, members are connected to each other via a suspension arm member so as to be able to swing vertically or the like. Examples of suspension arm members include a suspension arm mounted on a vehicle body or a wheel axle via a ball joint, a stabilizer link connecting a stabilizer bar and a stabilizer, and the like. Since strength and rigidity are required for such a suspension arm member, iron suspension arm members are generally used. Since the support rod of a normal stabilizer link is made of steel, it is heavy compared with a resin-made member or an aluminum member. [0003] In recent years, in the automotive field, due to the sharp rise in crude oil and gasoline prices, there has been a growing demand for improved fuel economy. In ord...
