Abstract

A multi-link type suspension system includes a knuckle for rotatably supporting an axle, an upper arm extending laterally of the vehicle body to connect the knuckle with the vehicle body above the axle, a leading arm extending outwardly and forwardly of the vehicle body from a rear inside position of the vehicle body to connect the knuckle with the vehicle body above the axle, a lower arm extending laterally of the vehicle body to connect the knuckle with the vehicle body below the axle, a trailing arm extending outwardly and rearwardly of the vehicle body from a front inside position of the vehicle body to connect the knuckle with the vehicle body below the axle, and a control arm extending laterally of the vehicle body to connect the knuckle with the vehicle body in rear of the axle. The longitudinal distance from an outer end of the control arm to an outer end of the leading arm is set larger than a longitudinal distance from an outer end of the upper arm to the outer end of the leading arm, and a longitudinal distance from the outer end of the control arm to an outer end of the trailing arm is set larger than a longitudinal distance from an outer end of the lower arm to the outer end of the trailing arm. Thus, it is possible to produce a toe-in during braking to enhance the steering stability.

Claims8

Dependent claims

A multi-link type suspension system, comprising:

a knuckle for rotatably supporting an axle,
five arms for connecting the knuckle to a vehicle body for vertical movement, and
a damper for buffering the vertical movement of the knuckle,
said five arms including an upper arm extending substantially parallel to the axle to connect the knuckle with the vehicle body above the axle, a leading arm extending outwardly and forwardly of the vehicle body from a rear inside position of the vehicle body to connect the knuckle with the vehicle body above the axle, a lower arm extending laterally of the vehicle body to connect the knuckle with the vehicle body below the axle, a trailing arm extending outwardly and rearwardly of the vehicle body from a front inside position of the vehicle body to connect the knuckle with the vehicle body below the axle, and a control arm extending laterally of the vehicle body to connect the knuckle with the vehicle body in a rear of the axle, a longitudinal distance from an outer end of the control arm to an outer end of the leading arm being set larger than a longitudinal distance from an outer end of the upper arm to the outer end of the leading arm, and a longitudinal distance from the outer end of the control arm to an outer end of the trailing arm being set larger than a longitudinal distance from an outer end of the lower arm to the outer end of the trailing arm wherein the system as arranged provides a toe-in to an associated wheel when a longitudinal load is applied to the outer ends of the upper and leading arms.

1 more element

A multi-link suspension system, comprising;

a knuckle for rotatably supporting an axle,
a first suspension mechanism including a pair of arms which support a longitudinal force of the knuckle above the axle and define an upper point of a king pin axis of a wheel,
a second suspension mechanism including a pair of arms which support a longitudinal force of the knuckle below the axle and define a lower point of the king pin axis of the wheel, and
a control arm extending laterally of the vehicle body to connect the vehicle body and the knuckle,
said knuckle being provided with a mounting portion extending rearwardly from the knuckle to rotatably connect an outer end of said control arm in order to convert a longitudinal force applied to said first suspension mechanism and a longitudinal force applied to said second suspension mechanism into a force for offsetting the knuckle inwardly of the vehicle body during braking of the wheel,
wherein said first suspension system includes an upper arm extending substantially parallel to the axle to connect the knuckle with the vehicle body above the axle, and a leading arm extending outwardly and forwardly of the vehicle body from a rear inside position of the vehicle body to connect the knuckle with the vehicle body above the axle to thereby provide a toe-in to an associated wheel when a longitudinal load is applied to the outer ends of the upper and leading arms, and
wherein a resilient bushing is provided at least at one of a connection of the leading arm with the knuckle and a connection of the leading arm with the vehicle body, said resilient bushing having a modulus of elasticity which is high in a direction of tension of the leading arm and low in a direction of compression of the leading arm.
