FRONT SUSPENSION FOR VEHICLE

Japanese Patent JPS63235110

A

PURPOSE:To reduce flatter and harshness by forming a rear side elastic bush in such a way as to display non-linear spring characteristics having two spring constants and setting a wheel support member and the instantaneous center of driving an overall control arm to the predetermined value. CONSTITUTION:A rear side elastic bush 24 has a hooking piece 66 made of a root part 66a and a tip part 66b comprising a rigid body and an intermediate part 66c comprising a rubber type elastic body, respectively between inner and outer cylinders 52 and 54, thereby forming the non-linear spring characteristics wherein the first spring constant is given for a lateral force equal to or less than the predetermined value and the second spring constant equal to or less than the spring constant of a front side elastic bush 22 is given for the lateral force more than the predetermined value. And the spring constant of the front side bush 22 and the first spring constant of the rear side bush 24 are set so that a wheel support member 10 and the instantaneous center of lengthwise drive for a control arm 12 will be behind the axial line of a tie rod 46. According to the aforesaid constitution, flatter and harshness can be reduced.
