Abstract

In a suspension support structure, an upper end of a piston rod of a damper is supported by a vehicle body. The suspension support structure is provided with a base body and a lid body which is press-fitted in the base body. The base body has a peripheral wall extending from a flange joined to the vehicle body, and a bottom formed at the lower end of the peripheral wall and through which the piston rod is inserted. An elastic body and the upper end of the piston rod are supported on the bottom. The lid-body is press-fitted to the inner surface of the peripheral wall such that the lid body covers at least the upper surface of the elastic body while facing the bottom of the base body. When the lid body is attached to the base body is contained below the upper end of the peripheral wall.

First claim

The invention claimed is:

1. A suspension support structure for supporting an upper part of a piston rod of a damper on a vehicle body, said suspension support structure comprising:
a bottomed tubular base member having an open end facing upward, the base member including a flange part extending radially outward from the open end and adapted to be coupled to the vehicle body, a tubular peripheral wall part extending vertically downward from an inner edge of the flange part, and a bottom part provided at a lower end of the peripheral wall part and having a through-hole for allowing passage of the piston rod therethrough;
an elastic member supported on the bottom part of the base member and adapted to be connected to the upper part of the piston rod; and
a bottomed tubular lid member having an open end facing downward, the lid member including a tubular peripheral wall part and a top plate part provided at an upper end of the peripheral wall part of the lid member,
wherein the tubular peripheral wall part of the lid member is press-fitted into the tubular peripheral wall part of the base member to thereby join the base member and the lid member with the elastic member accommodated therebetween, the top plate part of the lid member covering an upper surface of the elastic member, and
wherein the lid member has an upper end located below the inner edge of the flange part of the base member, and the lid member is held out of contact with the vehicle body.

2. The suspension support structure according to claim 1 , wherein the tubular peripheral wall part of the lid member has a piston-rod-axial-direction lower end part brought into abutment with the bottom part of the base member, the lower end part has an elastic-member-contacting inner surface being made flat, and an escape part formed on an outer surface opposed to the peripheral wall part of the base member and spaced from the peripheral wall part of the base member.

3. The suspension support structure according to claim 2 , wherein the base member has a curved part formed at a corner between the peripheral wall part and the bottom part of the base member, and the escape part has a depth larger than a depth of the cover part.

4. The suspension support structure according to claim 3 , wherein, in the piston-rod-axial-direction, part of the vehicle body is positioned in an overlapping relation to the lid member.

5. The suspension support structure according to claim 2 , wherein, in the piston-rod-axial-direction, part of the vehicle body is positioned in an overlapping relation to the lid member.

6. The suspension support structure according to claim 1 , wherein, in the piston-rod-axial-direction, part of the vehicle body is positioned in an overlapping relation to the lid member.

7. A suspension support structure for supporting an upper part of a piston rod of a damper on a vehicle body, and suspension support structure comprising:
a base member having a flange part adapted to be coupled to the vehicle body, a peripheral wall part extending from the flange part, and a bottom part provided at a lower end of the peripheral wall part and allowing passage of the piston rod therethrough, the base member supporting the upper part of the piston rod and an elastic member on the bottom part; and
a lid member configured to be pressed toward the bottom part of the base member in such a manner as to cover at least an upper surface of the elastic member and fitted within the peripheral wall part;
wherein the lid member has a piston-rod-axial-direction lower end part brought into abutment with the bottom part, the lower end port has an elastic-member-contacting inner surface being made flat, and an escape part formed on an outer surface opposed to the peripheral wall part and spaced from the peripheral wall part,
wherein the base member has a curved part formed at a corner between the peripheral wall part and the bottom part thereof, and
wherein the escape part has a depth larger than a depth of the curved part.

8. The suspension support structure according to claim 7 , wherein the elastic member has an outer peripheral surface, and the lid member is press-fitted between the base member and the elastic member in such a manner as not to allow the outer peripheral surface to contact the peripheral wall part.

9. The suspension support structure according to claim 8 , wherein, when the lid member is attached to the base member, an upper end part of the lid member is positioned below an upper end part of the peripheral wall part.

10. The suspension support structure according to claim 7 , wherein, when the lid member is attached to the base member, an upper end part of the lid member is positioned below an upper end part of the peripheral wall part.

11. The suspension support structure according to claim 7 , wherein, in the piston-rod-axial-direction, part of the vehicle body is positioned in an overlapping relation to the lid member.
