## Abstract

A light-alloy vehicle suspension member integrally made from a light alloy, including a sectional shape formed by an upper wall, a front wall, and a rear wall so as to have an open bottom, the upper wall being substantially horizontal, the front wall and the rear wall being erected in a substantially vertical manner on a front edge and a rear edge of the upper wall respectively, wherein: one end of a torque rod is connected to a center portion, in a vehicle width direction, of the upper wall, another end of the torque rod is connected to an engine; a vertical position of the upper wall substantially corresponds to a vertical center position between the front wall and the rear wall, and substantially corresponds to a height position of the torque rod.

## Claims

### Claim 1

A light alloy vehicle suspension member integrally made from a light alloy, including a sectional shape formed by an upper wall, a front wall, and a rear wall so as to be opened downward, the upper wall being substantially horizontal, and the front wall and the rear wall being erected in a substantially vertical manner on a front edge and a rear edge of the upper wall respectively, wherein:
one end of a torque rod is connected to a center portion, in a vehicle width direction, of the upper wall, and another end of the torque rod is connected to an engine;
a vertical position of the upper wall substantially corresponds to a vertical center position between the front wall and the rear wall, and substantially corresponds to a height position of the torque rod; and
the light alloy vehicle suspension member has a substantially H-shape form in a longitudinal section along a front and rear direction of the vehicle.

### Claim 2 (depends on 1)

The light alloy vehicle suspension member according to claim 1, wherein
a torque rod mounting portion of the upper wall bulges upward from the upper wall, and a housing portion for a mount of the torque rod is formed on a lower part of the torque rod mounting portion.

### Claim 3 (depends on 2)

The light alloy vehicle suspension member according to claim 2, wherein
vertical ribs connecting the front wall and the rear wall, are installed on left and right parts of the torque rod mounting portion respectively,
the vertical ribs are projected substantially vertically from an lower surface of the upper wall, and
the housing portion is configured by the vertical ribs, the front wall, and the rear wall.

### Claim 4 (depends on 3)

The light alloy vehicle suspension member according to claim 3, wherein
diagonal ribs are installed so as to be projected substantially vertically from the lower surface of the upper wall,
the diagonal ribs extend obliquely outward in the vehicle width direction from connecting portions in which the left and right vertical ribs are connected to the front wall and the rear wall, and
triangular spaces which are formed with a triangular shape when seen from an upper direction of the vehicle and are opened downward, are formed on the left and right parts of the torque rod mounting portion respectively by the diagonal ribs, the vertical ribs, and the upper wall.
