Abstract

A suspension apparatus for a vehicle adapted to decline the body and/or the wheels toward the turning center side according to the steering operation when the vehicle makes a turn. In this suspension apparatus, the end portion of a suspension spring at the vehicle body side or the end portion of an upper arm at the vehicle body side are secured to a movable member associated with a steering operation member for movement. In the vehicle equipped with this suspension apparatus, driver can enjoy the similar steering sense or feeling as a motorcycle.

Claims

1. A suspension apparatus for a vehicle provided between a pair of right and left wheels of the vehicle and the vehicle body characterized in that one end portion of a suspension spring at a vehicle body side is secured to a movable member associated with a steering operation member for movement, the other end portion of the suspension spring is connected to a suspension arm, a lever member pivotally connected to the vehicle body is connected to said movable member, and a tie rod is connected to said lever member, so that when the vehicle makes a turn, the vehicle body is caused to decline toward the turning center side according to the steering operation.

2. A suspension apparatus as claimed in claim 1, wherein a connecting point between said lever member and said movable member is movable along a predetermined slot in said lever member.

3. A suspension apparatus as claimed in claim 1, wherein a connecting point between said lever member and said vehicle body is movable along a predetermined slot in said lever member.

4. A suspension apparatus as claimed in claim 1, wherein said suspension spring is connected at its other end to a lower suspension arm, said movable member is connected to one arm portion of said lever member, an upper suspension arm is connected to the other arm portion of said lever member, and a tie rod is connected to a portion of said lever member pivotally connected to the vehicle body.

5. A suspension apparatus for a vehicle provided between a pair of right and left wheels of the vehicle and the vehicle body, the vehicle further including a steering operation member and a movable member associated with the steering operation member for movement laterally of the vehicle body upon turning of the steering operation member, said apparatus comprising on each side of said vehicle body:

a lower suspension arm pivotally connected to the vehicle body and the respective wheel,

a suspension spring connected between the movable member and said lower suspension arm,

a lever member pivotally connected to the vehicle body and connected to the movable member, and

a tie rod connected to a portion of said lever member and the respective wheel;

whereby when the vehicle makes a turn, the vehicle body is caused to decline toward a turning center side according to the steering operation.

6. A suspension apparatus as claimed in claim 5, wherein said lever member has a slot in one portion thereof and said movable member includes a pin engaged in said slot and movable therealong.

7. A suspension apparatus as claimed in claim 6, wherein said lever member has a mid-portion and two arm positions, said slot being in one arm portion and said tie rod being pivotally connected to the other arm portion.

8. A suspension apparatus as claimed in claim 10, wherein said lever member has a mid-portion and two arm portions, said lower member being pivotally connected to the body member at one arm portion, said slot being in said mid-portion, and said tie rod being pivotally connected to the other arm portion.

9. A suspension apparatus as claimed in claim 5, wherein said lever member has a slot in one end portion thereof and the vehicle body includes a pin engaged in said slot and movable therealong.

10. A suspension apparatus as claimed in claim 5 wherein said lever member includes a mid-portion and two arm portions, said lever member being pivotally connected to the vehicle body at said mid-portion, said tie rod being connected to said lever member at said mid-portion, and said movable member is connected to one of said arm portions of said lever member;

said apparatus further comprising at each side of the vehicle body;

an upper suspension arm connected to the respective wheel and to the other of said arm portions of the respective lever member.

11. A suspension apparatus as claimed in claim 10 wherein said one arm portion of said lever member has a slot therein and said movable member includes a pin engaged in said slot and movable therealong.
