    • A compact suspension system for a wheeled vehicle and method for its manufacture. The suspension includes a tapered, vertically mounted elongated arm (6,8) having an integral eye (14) at one end. The integral eye (14) rotatably connects the elongated arm (6,8) to the vehicle while the other end connects to an air spring (21) attached to the vehicle. The axle (2) connects to the arm (6,8) near the air spring (21). The arm is tapered between the axle (2) and the integral eye (14) so that the amount of arm material, and thus weight, is reduced. A second arm is placed adjacent to, and parallel with, the first arm to back up the first arm if the first arm fails, or vice versa. A shock absorber (32) is mounted near the axle (2) on the opposite side of the axle (2) as the air spring (21). The method of manufacture includes plasma cutting a blank elongated arm from spring steel, heat-treating the arm, machining to final form, and then shot peening the arm.
    • 一种紧凑的悬挂系统用于轮式车辆和方法,用于其制造。 该悬浮液包括具有在一个端部一体地眼(14)的锥形的,细长的垂直安装的臂(6.8)。 积分眼(14),而另一端连接到在连接到车辆空气弹簧(21)可旋转地连接所述细长臂(6.8)至车辆。 轴(2)连接到所述臂(6.8)的空气弹簧(21)的附近。 该臂轴(2)及积分眼(14)象臂材料,因此重量的量之间逐渐变细,减少。 第二臂被放置在相邻的,并与其它并行,第一臂备份第一臂如果第一失败臂,或反之亦然。 减震器(32)安装在轴(2),作为空气弹簧(21)的相反侧上的轴(2)的附近。 制造的方法包括等离子体由弹簧钢切割空白细长臂,热处理所述差,加工成最终形状,然后喷丸的差。
