Wheeled vehicle with two adjacent rigid axles, each with independent suspension

摘要

A suspension comprising a combination of the following features is proposed for a wheeled vehicle in which two adjacent rigid axles (2, 3) are respectively supported on the vehicle frame (1), each by way of two leaf spring elements (7, 8). The leaf spring elements (7, 8) are arranged inclined at an acute angle @ to the vehicle road contact plane (12), rising towards the rear. The front and rear leaf spring elements (7, 8) on each side of the vehicle partially overlap one another and are connected by their ends in the overlap area to a common support element (10). This is designed as bearing bracket in such a way that it simultaneously serves as the element absorbing the axle lateral forces of both rigid axles (2, 3). Each leaf spring element (7 and 8), viewed in the direction of travel (4), is rigidly connected to a support element (9 and 10) at the front, but otherwise suspended on a short axle beam (14 and 16) so that it overhangs at the rear. Furthermore, the distance (d) from the front bearing point (11) of a front leaf spring element (7) to the middle of the front rigid axle (2) is greater than the distance (f) of the front bearing point (16) of a rear leaf spring element (8) from the middle of the rear rigid axle (3). This results in a robust spring arrangement of very low height on the wheel vehicle, with favourable absorption of lateral forces. <IMAGE>
