Suspension device for vehicles

A suspension device for vehicles, the suspension device comprising:

• a damper disposed between a wheel of a vehicle and a vehicle body of the vehicle and configured to extend and retract between the wheel and the vehicle body;
• a shaft configured to pivotably support an end of the damper;
• a bush including a cylindrical elastic member fitted onto an outer circumference of the shaft and interposed between the shaft and the damper;
• a pair of left and right trailing arms extending in a longitudinal direction of the vehicle;
• and
• a bracket connected to one of the pair of left and right trailing arms,
• wherein
• the bush is mounted to the bracket such that an axis of the bush is disposed along a line of intersection between an imaginary first plane and an imaginary second plane, or along a line parallel to the line of intersection, the first plane being orthogonal to an axis of the damper when a stroke position of the wheel is a first position relative to the vehicle body in a vertical direction of the vehicle body, the second plane being orthogonal to the axis of the damper when the stroke position of the wheel is a second position different from the first position,
• the first position is close to a bump side relative to a predetermined reference position,
• the first position is a position at a time when two people having a certain weight are seated in front seats of the vehicle stopping on a horizontal road surface,
• the second position is close to a rebound side relative to the predetermined reference position, and
• the second position is a position in which the damper is most extended.

• a bracket connected to one of the pair of left and right trailing arms, wherein
• the bush is mounted to the bracket with the axis of the bush inclined in the vehicle width direction, in the vertical direction of the vehicle body, and in a longitudinal direction of the vehicle such that the axis of the bush is disposed along a line of intersection between an imaginary first plane and an imaginary second plane, or along a line parallel to the line of intersection, the first plane being orthogonal to an axis of the damper when a stroke position of the wheel is a first position relative to the vehicle body in a vertical direction of the vehicle body, and the second plane being orthogonal to the axis of the damper when the stroke position of the wheel is a second position different from the first position.
