Embodiment Construction

[0023] Next, the peripheral structure of the suspension frame according to the embodiment of the present invention will be described. In addition, this embodiment will be described using the vehicle body front portion of a front-engine front-wheel drive (FF) type vehicle.

[0024] refer to figure 1A pair of side frames 2 constituting a frame of the vehicle body are provided on the vehicle body front portion 1 , and the pair of side frames 2 are arranged along the vehicle front-rear direction and at a distance from each other in the vehicle width direction. A pair of lower arms 3 constituting a suspension mechanism are provided in the vehicle body front portion 1 , and the lower arms 3 are arranged below the side frame 2 . In addition, a suspension frame 4 is disposed between the pair of side frames 2 . Although not particularly shown, drive mechanisms such as an engine and a transmission are arranged on the front side of the suspension frame 4 , and side frames 2 are arrange...

Abstract

The structure has side parts (2) arranged on sides of a driving mechanism of a motor vehicle. A torque rod (5) connects the driving mechanism and a suspension frame (4), where the frame has front and rear arms. The front arms run outwardly from ends of a middle connection body to a vehicle breadth direction, and the rear arms are arranged behind the front arms. The front and rear arms are fastened to the side parts, and an end of the rod is connected to the body. The front arms or the rear arms are formed in an arcuate shape such that the body lies at a distal end in a plan view.

Description

technical field [0001] The present invention relates to a peripheral structure of a suspension frame arranged between a pair of left and right side frames in the vehicle width direction. Background technique [0002] In a vehicle such as an automobile, a pair of side frames are provided at a distance from each other in the vehicle width direction as members constituting the frame of the vehicle body. Around each pair of side frames, a lower arm is provided as a part constituting the suspension mechanism, and when the vehicle is running, load and vibration are input from the wheels to the vehicle body through the lower arm. Such loads and vibrations include, for example, loads and vibrations in the vehicle width direction when the vehicle is turning, loads and vibrations in the front and rear directions of the vehicle when the vehicle is braking and accelerating, and loads and vibrations in the vertical direction caused by unevenness of the road surface. Vibration, loads and...
