Description

Hang the peripheral construction of vehicle frame
Technical field
The present invention relates to the peripheral construction of the suspension vehicle frame between a kind of side vehicle frame being configured in vehicle-width direction pair of right and left.
Background technology
In the vehicles such as automobile, as the parts forming body framing, be separated with mutually compartment of terrain in the vehicle width direction and be provided with an offside vehicle frame.At offside vehicle frame periphery separately, be provided with underarm as the part forming hitch, when vehicle travels, load and vibration can be imported into car body from wheel via underarm.As such load and vibration, such as, when can list the load of the vehicle-width direction of Ackermann steer angle and vibration, car brakeing and the load of the vehicle fore-and-aft direction in the time of acceleration and vibration, by the load of the concavo-convex above-below direction caused on road surface and vibration, the load be made up of these load and vibrations synthesis composition and vibration etc.In addition, also exist from vehicle fore-and-aft direction or vehicle-width direction the situation of the direct applied load of car body.Such load and vibration become the riding stability that can cause reducing vehicle, and in compartment, produce the major cause of vibration and noise.In order to tackle such problem, improve the rigidity of car body for bearing load and vibration, between an offside vehicle frame and between a pair underarm, suspension has suspension vehicle frame.
As an example with the structure hanging vehicle frame, in patent documentation 1, the supporting member (side member portion) extended to vehicle fore-and-aft direction is configured with in the below of the front side vehicle frame (front side member) of vehicle-width direction pair of right and left, at the underarm installation portion of the leading section and rearward end that are arranged at supporting member respectively, suspension underarm is installed, between a pair supporting member, suspension has the suspension vehicle frame (rack housing) extended with linearity along vehicle-width direction, the both ends hanging the vehicle-width direction of vehicle frame are arranged on the pars intermedia of the vehicle fore-and-aft direction of supporting member.In addition, between the suspension vehicle frame installation portion of the underarm installation portion in the front side of supporting member and supporting member, front side car body installation portion is provided with along vehicle above-below direction, also be provided with from the underarm installation portion of the rear side of supporting member to vehicle-width direction rear side car body installation portion protruding outside, supporting member utilizes front side car body installation portion and rear side car body installation portion to be installed on front side vehicle frame.
Patent documentation 1: Japanese Unexamined Patent Publication 2001-191945 publication
But, in the structure of patent documentation 1, hang vehicle frame just to extend along vehicle-width direction with linearity, be difficult to utilize and hang load and the vibration that vehicle frame sustains vehicle fore-and-aft direction, suspension vehicle frame cannot be utilized to improve the load of car body relative to vehicle fore-and-aft direction and the rigidity of vibration efficiently.
For the relation of the suspension vehicle frame in the structure of patent documentation 1 and front side vehicle frame, the both ends hanging vehicle frame are arranged on the pars intermedia of supporting member, at the front side of supporting member, the front side car body installation portion being configured in the pars intermedia front of supporting member is installed on front side vehicle frame, at the rear side of supporting member, the rear side car body installation portion being configured in the underarm installation portion on rear side of supporting member is installed on front side vehicle frame.In this configuration, when hanging vehicle frame and bearing load and the vibration of vehicle-width direction, the moment rotated centered by the axis extended along the vertical direction can be applied to the front side car body installation portion and rear side car body installation portion laying respectively at front side and rear side relative to the both ends hanging vehicle frame.In addition, when hanging vehicle frame and bearing load and the vibration of above-below direction, can apply to front side car body installation portion and rear side car body installation portion the moment that rotates centered by the axis extended along vehicle-width direction.But, in the structure of patent documentation 1, this moment cannot be sustained fully.Therefore, in the structure of patent documentation 1, be difficult to the load and the vibration that sustain vehicle-width direction, suspension vehicle frame cannot be utilized to improve the load of car body relative to vehicle-width direction and the rigidity of vibration efficiently.
