Embodiment Construction

[0023] Embodiments of the present invention shown in the drawings are described below.

[0024] A cross member 1 extending in the vehicle width direction is connected to a vehicle body (not shown). The left and right ends of the beam 1 are respectively connected to one end of the suspension lower arm 2 and one end of the suspension upper arm 4 through the tower 3 in a pivoting manner. The wheels, not shown, are mounted on a steering knuckle 5 that spans between the two arms 2 and 4 . The shock absorber 6 is connected so as to straddle the suspension lower arm 2 and the tower 3 . According to this embodiment, the wheel support comprises two arms 2 and 4 and a steering knuckle 5 .

[0025] Further, a receiver 8 is mounted on a substantially trapezoidal groove portion 7 on each of the right and left suspension lower arms 2 . Two leaf springs 9 and 10 made of spring steel are stacked and arranged along the cross member 1 so as to extend in the vehicle width direction. The left...

Abstract

A suspension includes: wheel supporting members for supporting wheels, a leaf spring having both end portions each arranged on an upper side of the respective wheel supporting member; a pivot supporting the leaf spring, and receiving pieces interposed between the wheel supporting members and the both end portions of the leaf spring respectively. Each of the wheel supporting members includes a recess portion on which one of the receiving pieces is mounted. Each of the receiving pieces includes an engaging portion for engaging with one of the both end portions of the leaf spring. Each of the receiving pieces includes an elastic member and a first metal plate joined on the elastic member. The elastic member can deform to follow a displacement of a relative position between the leaf spring and one of the wheel supporting members.

Description

[0001] The present invention is related to the subject matter of Japanese Patent Application No. 2002-156541 filed May 30, 2002, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a vehicle suspension, and more particularly to a side-mounted leaf spring type independent suspension for independently suspending wheels on both sides of a vehicle by using leaf springs arranged in a vehicle width direction. Background technique [0003] JP11263109A discloses a general example of a side-mounted leaf spring type independent suspension in which wheels are independently suspended on both sides of the vehicle by using leaf springs arranged along the vehicle width direction. The middle part of the leaf spring is supported, and the two ends of the leaf spring are engaged with the wheel support through the eyelet. Since the above-mentioned conventional suspension has a complicated structure in which both end portio...
