Abstract

A damper housing includes an upper-wall-plate and an upper-wall-reinforcement-plate. A plurality of collars through which fastening members for attaching a damper are interposed between the upper-wall-plate and the upper-wall-reinforcement-plate. The collars are disposed on a circumference around the damper. An upper section of the damper is fastened and fixed to the upper-wall-reinforcement-plate and the upper-wall-plate by the fastening members. A concave section is formed in at least one of the upper-wall-plate and the upper-wall-reinforcement-plate which are facing each other, the concave section being formed so as to protrude toward the facing upper-wall-plate or the upper-wall-reinforcement-plate. The concave section is disposed between the neighboring collars on the circumference on which the collars are disposed. The upper-wall-plate and the upper-wall-reinforcement-plate are coupled to the facing upper-wall-plate or the upper-wall-reinforcement-plate at the concave section.

First claim

What is claimed is:

1. A damper housing for a vehicle configured to support a load input from a damper of a suspension, the damper housing for a vehicle comprising:
an upper wall plate configured to cover the damper from at least above; and
an upper wall reinforcement plate coupled to the upper wall plate at below the upper wall plate,
wherein a plurality of collars through which fastening members for attaching the damper are inserted are interposed between the upper wall plate and the upper wall reinforcement plate, the plurality of collars being disposed on a circumference about a central axis of the damper,
an upper section of the damper is fastened and fixed to the upper wall reinforcement plate and the upper wall plate by the fastening members inserted through the collars,
a first concave section is provided in at least one of the upper wall plate and the upper wall reinforcement plate which are facing each other, the first concave section being formed on the upper wall plate or the upper wall reinforcement plate so as to protrude toward the facing upper wall plate or the upper wall reinforcement plate and being disposed between the neighboring collars among the circumference on which the collars are disposed, and
the upper wall plate or the upper wall reinforcement plate are coupled to the facing upper wall plate or the upper wall reinforcement plate at the first concave section.

2. The damper housing for a vehicle according to claim 1 , further comprising a lateral member configured to connect the upper wall plate and the upper wall reinforcement plate to an upper member of a side portion of the vehicle at an outer side position of the upper wall plate in a vehicle width direction,
wherein the upper wall plate and the upper wall reinforcement plate are formed in a substantially rectangular shape when seen in a plan view,
a second concave section is provided in at least one of the upper wall plate and the upper wall reinforcement plate which are facing each other, the second concave section being formed on the upper wall plate or the upper wall reinforcement plate so as to protrude toward the facing upper wall plate or the upper wall reinforcement plate and being disposed in a vicinity of a corner section of the upper wall plate or the upper wall reinforcement plate which is located at outer side in the vehicle width direction, and
the lateral member is coupled to at least one of the upper wall plate and the upper wall reinforcement plate at a position adjacent to the second concave section.

3. The damper housing for a vehicle according to claim 1 , further comprising:
a front wall plate configured to cover at least a front of the damper; and
a rear wall plate configured to cover at least a rear of the damper,
wherein the upper wall plate has a substantially flat upper wall main body section configured to support an upper end portion of the damper and an upper wall bent section extending to be bent downward from an end portion of the upper wall main body section,
the front wall plate has a front wall main body section configured to cover the front of the damper and a front wall bent section extending to be bent rearward from an inner end portion of the front wall main body section in the vehicle width direction,
the rear wall plate has a rear wall main body section configured to cover the rear of the damper and a rear wall bent section extending to be bent forward from an inner end portion of the rear wall main body section in the vehicle width direction, and
the front wall plate and the rear wall plate are coupled to each other at the front wall bent section and the rear wall bent section, the upper wall plate being coupled to the front wall plate and the rear wall plate at the upper wall bent section.

4. The damper housing for a vehicle according to claim 3 , wherein the upper wall main body section has a lateral side extending substantially in a vehicle forward/rearward direction at inner side in the vehicle width direction, a front side extending substantially in the vehicle width direction at forward side in the vehicle forward/rearward direction, and a rear side extending substantially in the vehicle width direction at rearward side in the vehicle forward/rearward direction,
the upper wall bent section has a side bent piece extending to be bent downward from the lateral side, a front bent piece extending to be bent downward from the front side, and a rear bent piece extending to be bent downward from the rear side, and adjacent pieces of the side bent piece, the front bent piece and the rear bent piece are formed as an integrated structure, and
suspension support members are attached to sections in the vicinity of a three-face joining section in which the upper wall main body section, the side bent piece and the front bent piece are substantially perpendicular to each other and a three-face joining section in which the upper wall main body section, the side bent piece and the rear bent piece are substantially perpendicular to each other.

5. The damper housing for a vehicle according to claim 4 , comprising a connecting point of a tower bar configured to minimize twisting of left and right damper support sections of the vehicle,
wherein the connecting point is disposed in a vicinity of the three-face joining section of the upper wall main body section.

6. The damper housing for a vehicle according to claim 3 , wherein the upper wall reinforcement plate has an upper wall reinforcement main body section disposed so as to face a lower side of the upper wall main body section, and an upper wall reinforcement bent section extending to be bent downward from an edge of the upper wall reinforcement main body section, and
the upper wall reinforcement bent section is coupled to the upper wall bent section.

7. The damper housing for a vehicle according to claim 6 , further comprising an upper connecting plate that is disposed at least at one of between the upper wall main body section and an upper position of the front wall main body section and between the upper wall main body section and an upper position of the rear wall main body section and that is configured to connect the upper wall plate to the upper member of the side portion of the vehicle,
wherein the upper connecting plate has a coupling flange joined to the upper wall bent section at a position in front of or rear of the upper wall plate,
a suspension support member extending outward from the front wall bent section or the rear wall bent section in the vehicle width direction is interposed between the upper wall bent section and the coupling flange,
the coupling flange has a cutout section, and
the suspension support member is joined to at least one member of the upper wall bent section and the upper wall reinforcement bent section in the cutout section of the coupling flange, and joined to at least the coupling flange among the coupling flange and the upper wall bent section in an area in which the cutout section is not present.

8. The damper housing for a vehicle according to claim 7 , wherein the upper connecting plate has a crank-shaped cross-sectional shape extending substantially in the vehicle width direction.
