Abstract

A subframe structure being supported by a vehicle-body frame and supporting a vehicular power plant through a damping device. The subframe structure includes: a longitudinal member which extends in a front-rear direction of a vehicle and is rigidly fixed to the vehicle-body frame; a lateral member which extends in a vehicle width direction and on which at least one of the damping devices is mounted; a floating mechanism which floatingly supports the lateral member on the longitudinal member through an elastic mechanism; and a suspension arm connected to the longitudinal member.

First claim

What is claimed is:

1. A subframe structure configured to be supported by a vehicle-body frame and to support a vehicular power plant through damping devices, said subframe structure comprising:
a longitudinal member which extends in a front-rear direction of a vehicle and is rigidly fixed to the vehicle-body frame;
a lateral member which extends in a vehicle width direction and on which at least one of the damping devices is mounted;
a floating mechanism which floatingly supports the lateral member on the longitudinal member through an elastic mechanism, and which cooperates with said at least one of the damping devices such that, during operation, phases of elastic resonant vibrations of the longitudinal member and the lateral member are opposite to each other; and
a suspension arm connected to the longitudinal member.

2. The subframe structure according to claim 1 , wherein the lateral member includes a front lateral member which is floatingly mounted on a front portion of the longitudinal member through the floating mechanism.
