Rear suspension apparatus for motor vehicle

Abstract

A rear suspension apparatus for a motor vehicle having a differential gear case ( 2 ) disposed between rear right- and left-wheels ( 1 R, 1 L), which is of a torsion beam type. In the rear suspension apparatus, a central portion ( 12 a ) of a torsion beam ( 12 ) for rotatably supporting the rear right- and left-hand wheels ( 1 R, 1 L) is curved to run along the configuration of the differential gear case ( 2 ), and is disposed at the rear of the differential gear case ( 2 ). A suspension damper ( 16 ) stretched between the torsion beam ( 12 ) and the vehicle body is disposed to be inclined upwardly and forwardly.

What is claimed is:  
     
         1 . A torsion beam type rear suspension apparatus for a motor vehicle having a differential gear case disposed between rear right- and left-wheels, wherein a central portion of a torsion beam in a width direction of said motor vehicle is bent along a configuration of said differential gear case, and is located at the rear of said differential gear case, and a suspension damper placed between said torsion beam and a body of said motor vehicle is disposed in a state of being inclined upwardly and forwardly.  
     
     
         2 . A torsion beam type rear suspension apparatus for a motor vehicle having a differential gear case disposed between rear right- and left-wheels, wherein a central portion of a torsion beam in a width direction of said motor vehicle is bent along a configuration of said differential gear case, and is located at the rear of said differential gear case, and wherein said differential gear case has a curved section protruding rearwardly, and said central portion of said torsion beam is placed at a lower position than a peak portion of said curved section.  
     
     
         3 . A torsion beam type rear suspension apparatus for a motor vehicle having a differential gear case disposed between rear right- and left-wheels, wherein a central portion of a torsion beam in a width direction of said motor vehicle is bent along a configuration of said differential gear case, and is located at the rear of said differential gear case, and wherein said central portion of said torsion beam is formed to be at a higher position than both end portions thereof in said vehicle width direction.  
     
     
         4 . A torsion beam type rear suspension apparatus for a motor vehicle having a differential gear case disposed between rear right- and left-wheels, wherein said torsion beam is connected to said vehicle body through a lateral link extending in said vehicle width direction, and said lateral link is disposed to be inclined up and down in said vehicle width direction, with its upper end portion being connected to said vehicle body while its lower end portion being connected to said torsion beam.  
     
     
         5 . A torsion beam type rear suspension apparatus for a motor vehicle having a differential gear case disposed between rear right- and left-wheels, wherein an exhaust pipe extending from an engine is bent for bypassing said torsion beam to pass above said torsion beam, and extends to a rear section of said vehicle body, and a portion of said exhaust pipe rearwardly extending from the curved portion is disposed to run from above said torsion beam to below said torsion beam to cross said torsion beam, and is inclined downwardly and rearwardly.  
     
     
         6 . A torsion beam type rear suspension apparatus for a motor vehicle having a differential gear case disposed between rear right- and left-wheels, wherein a central portion of a torsion beam in a width direction of said motor vehicle is bent along a configuration of said differential gear case, and is located at the rear of said differential gear case, and wherein a recessed space formed to a floor panel of said vehicle body and enlarging protrusively and downwardly is placed at the rear of said torsion beam, and the height of a lower end portion of a front wall defining said recessed space is set to exceed the height of an upper end portion of said torsion beam.  
     
     
         7 . A rear suspension apparatus for a motor vehicle as defined in  claim 6 , wherein said front wall extends at least from above said torsion beam to under said torsion beam, and is inclined downwardly and rearwardly.  
     
     
         8 . A rear suspension apparatus for a motor vehicle as defined in  claim 6 , wherein said lateral link is placed between said front wall and said torsion beam.
