Abstract

A suspension device according to the present disclosure which is equipped with an upper arm, a lower arm, and a leaf spring, wherein: the intermediate section of the leaf spring is housed inside a main cross member among the suspension cross members; the main cross member among the suspension cross members is connected to the side member via a hollow bracket; the hollow bracket has a bracket shock absorber positioned so as to face the lower arm; and the hollow bracket has a reinforcing part which faces the bracket shock absorber.

First claim

The invention claimed is:

1. A suspension device comprising:
an upper arm that is configured to swingably support a knuckle of a wheel and configured to be swingably supported by a side member extending in a vehicle front-rear direction;
a lower arm that is provided to swingably support the knuckle and configured to be swingably supported by a suspension cross member extending in a vehicle width direction; and
a leaf spring that is disposed to extend in the vehicle width direction and has an end portion disposed in the lower arm,
wherein an intermediate part of the leaf spring is accommodated in a main cross member of the suspension cross member,
the main cross member of the suspension cross member connects to the side member via a hollow bracket,
the hollow bracket includes a bracket shock absorber positioned to face the lower arm,
the hollow bracket includes a reinforcing portion facing the bracket shock absorber,
the hollow bracket includes an outer case member and an inner case member, and
each of the outer case member and the inner case member has a connection region with the main cross member on a vertically upper side of the main cross member.

2. The suspension device according to claim 1 ,
wherein a reinforcing rib is arranged inside the hollow bracket as the reinforcing portion.

3. The suspension device according to claim 2 ,
wherein a shock absorbing device is arranged between the lower arm and the side member, and
the upper arm and the shock absorbing device are in a disconnected state with the hollow bracket.

4. The suspension device according to claim 1 ,
wherein a shock absorbing device is disposed between the lower arm and the side member, and
the upper arm and the shock absorbing device are in a disconnected state with the hollow bracket.
