Abstract

Provided is a suspension device in which a load axis of a spring is significantly inclined with respect to a center axis of an absorber. The suspension device includes a support section formed between an end portion of the spring on a spring seat side and a mount, for realizing a “full contact state” during assembly and a “partial contact state” after assembly. With this, it is possible to provide the suspension device in which the assembly is facilitated and the load axis of the spring is significantly inclined with respect to the center axis of the absorber.

First claim

The invention claimed is:

1. A vehicle suspension device, comprising:
an absorber;
an outer cylinder having the absorber built therein;
a coil spring having a load axis which is inclined with respect to a center axis of the absorber and a center axis that is arranges coaxially with the center axis of the absorber, the coil spring comprising a spring portion that functions as a spring and end turn portions formed at both ends of the springs, the end turn portions being flat portions that do not function as a spring;
a spring seat on which the coil spring is mounted, the spring seat being provided on an outer circumference of the outer cylinder; and
an upper support for holding the coil spring between the upper support and the spring seat; wherein:
the spring seat is provided with a support member,
the support member being configured to support the spring portion while being in abutting contact with the spring seat and the spring portion during assembly,
the support member is not in abutting contact with the spring portion and does not support the spring portion with respect to the spring seat during a usage state after the assembly.

2. A vehicle suspension device according to claim 1 , wherein:
the support member comprises:
a mount interposed between the end turn portions and the spring seat; and
a projection portion formed on the support member, and
the spring seat has a hole formed therein so as to be opposed to the projection portion.

3. A vehicle suspension device according to claim 1 ,
wherein the support member has a projection portion formed thereon, and
wherein the spring seat has a hole formed therein so as to be opposed to the projection portion.

4. A vehicle suspension device according to claim 1 , wherein the support member comprises a plastically deformable member.

5. A vehicle suspension device according to claim 1 ,
wherein a number of turns of one of the end turn portions of the coil spring on the spring seat side is less than one, and
wherein the support member is formed between the spring seat and a part of the spring portion corresponding to a region, in which the one of the end turn portions on the spring seat side is absent, when the coil spring is viewed from the spring seat side along a center axis of the coil spring.
