Axle beam type suspension arrangement for vehicle

摘要

An axle beam suspension arrangement comprises a lateral link assembly which is mounted to a single support point on a vehicle body and two support points on an axle beam of the vehicle. The lateral link assembly consists of a lateral link member connected between a support point on the axle beam and the support point on the vehicle body, an assist link is provided which connects between the second support point on the axle beam and a point on the length of the lateral link, closer to the end at which the lateral link connects to the axle than the end connecting to the vehicle body. The lateral link is connected to the axle beam support point via a bush which is flexible in the axial direction of the lateral link. Thus scuff, or vertical disalignment of the vehicle wheels during bounding and rebounding is prevented while occurrence of rolling may be detected while jack-up forces applied to vehicle wheels are absorbed. The arrangement is further applicable to watt link type suspension arrangements incorporating to lateral links and an intermediate link. According to this arrangement, road unevenness input to the lateral links is absorbed by rotation of the intermediate link.
