Problems solved by technology

The distance between the point where the main lock shaft connecting the two spherical joints meets the ground and the ground center of the tire is called the friction radius (also called the main lock inclination angle). If the friction radius is too large, the steering load will increase. The problem of increased reaction force on the road surface

Embodiment Construction

[0026] Below, see attached Figure 1 Embodiments of the present invention will be described.

[0027] figure 1 It is an isometric projection showing one embodiment of the suspension structure for vehicles of the present invention.

[0028] figure 1 An exemplary suspension structure 1 for a vehicle is a double wishbone type including an upper arm (upper suspension arm) 10 , a lower arm (lower suspension arm) 20 and a wheel assembly unit 30 .

[0029] upper arm 10 as figure 1 The example shown is roughly U-shaped, and is swingably mounted on the suspension assembly element 120 through the pivot 11 . The suspension assembly element 120 is fixed on the vehicle body frame (ladder side frame) 110 extending in the front-rear direction of the vehicle (vehicle longitudinal direction). The upper arm 10 extends in the left-right direction of the vehicle body from a pivot 11 serving as a swing center.

[0030] lower arm 20 as figure 1 The example shown is roughly A-shaped, and is s...

Abstract

A vehicle suspension structure having: a suspension arm (20) extending in the left-right direction of the vehicle chassis from a pivot shaft (21), which is the center of vibrations; a vehicle-wheel attachment unit (30) which has a vehicle wheel attached thereto and drives the vehicle wheel; and a ball joint (22) connected to the suspension arm (20) and positioned in a location that intersects therotational center line of the vehicle wheel driven by the vehicle-wheel attachment unit (30).

Description

technical field [0001] The present invention relates to a suspension arrangement for a vehicle. Background technique [0002] A wide variety of suspension configurations for vehicles are known. [0003] JP2007-126005A describes a double wishbone front suspension. In the double wishbone type, an upper suspension arm (hereinafter appropriately referred to as an "upper arm") and a lower suspension arm (hereinafter appropriately referred to as a "lower arm") are connected to a steering knuckle (wheel assembly element) via a ball joint. The distance between the point where the main lock shaft connecting the two spherical joints meets the ground and the ground center of the tire is called the friction radius (also called the main lock inclination angle). If the friction radius is too large, the steering load will increase. The problem of increased reaction force on the road surface. [0004] Here, in general, the suspension geometry is designed in such a way that the ball joint...
