    • The suspension system is of the independent wheel support type incorporating what is known as the twin I-beam construction which is normally applied to front wheels but may be readily applied to rear wheels. An elongate fore and aft frame carries a cross member to which the suspension members are attached. A first axle member is pivoted to an end of the cross member and extends across and beyond the frame to carry a wheel at its free end. A second axle member is pivoted to the other end of the cross member and extends across in the opposite direction close to and generally parallel to the first one. Primary spring means bear down on the axle members near their free ends to take the normal load. An upwardly convex arched leaf spring is provided to take overloads and is located generally parallel to the axle members above them and beneath the cross member. The mid-point of the spring contacts and bears up against the cross member, and each end contacts and bears down against one of the axle members adjacent to their connections to the primary spring means. The auxiliary spring does not interfere with the normal action of the primary spring means.
    • 悬挂系统是独立的车轮支撑型,包括通常应用于前轮但可以容易地应用于后轮的所谓的双I型梁构造。 细长的前后框架承载悬挂构件所附接的横向构件。 第一轴构件枢转到横向构件的端部并且延伸穿过框架并且超过框架以在其自由端处承载车轮。 第二轴构件枢转到横向构件的另一端并且在靠近并且大致平行于第一构件的相反方向上延伸。 主弹簧意味着在自由端附近的轴构件上承受正常负载。 提供向上凸的弓形板簧以承受过载,并且大致平行于它们上方的轴构件并且在横梁下方定位。 弹簧的中点接触并抵靠横向构件,并且每个端部接触并且抵靠与其与主弹簧装置的连接相邻的轴构件中的一个。 辅助弹簧不会干扰主弹簧装置的正常动作。
