    摘要： The present invention includes a flexible, resilient composite spring pivotally connected to the vehicle wheel assembly by standard means such as a ball joint and knuckle. The composite spring is formed having a sinusoidal profile with rectangular cross-section preferably spanning transversely between parallel vehicle wheel assemblies. The composite spring is pivotally connected to the parallel vehicle frames by opposing perpendicular brackets welded to an upper and lower portion of the vehicle frame. A rubber bushing is preferably provided within each bracket and is in contact with opposing sides of the composite spring, allowing the spring to pivot between the vehicle frame. The composite spring is preferably formed with carbon and glass fibers. The sinusoidal composite spring blank is preferably molded with a neutral axis extending along the length of the spring at a midpoint of the sinusoidal profile.

    摘要： A stiff torque box is used with frame rail segments to compose a vehicle frame. The stiff torque box is used to cross-link the left hand and right hand sides of a vehicle frame and is made up of an extruded aluminum skeleton which forms a number of internal cavities, as well as connecting tabs. The connecting tabs are used to fix the frame rail segments to the stiff torque box. Implementing stiff torque boxes in vehicle frame construction allows for more rigid vehicle frames with the advantage of additional weight savings. This construction is ideal for aluminum frame, front wheel drive and body on frame vehicles. Because of the characteristics of such a vehicle frame, opportunities arise to implement other weight conservative vehicle components.

    摘要翻译： 一个刚性扭矩箱与框架轨道段一起使用以组成一个车架。 刚性扭矩箱用于交叉车架的左手和右侧，并由形成多个内腔的挤压铝骨架以及连接翼片组成。 连接翼片用于将框架轨道段固定到刚性扭矩箱。 在车架结构中实施刚性转矩箱允许更加刚性的车架，具有额外的重量减轻的优点。 这种结构是铝框架，前轮驱动和车身车身的理想选择。 由于这种车架的特点，出现了实现其它重量保守车辆部件的机会。

    摘要： A vehicle suspension system is provided including a trailing arm which is adapted to be pivotally connected to a frame of the vehicle. A wheel assembly is mounted to a first end of the trailing arm and a torsion element is integrally mounted within the trailing arm. A crank arm is provided having a first end mounted to the torsion element and a second end which is substantially fixed against movement in a vertical direction. As the trailing arm moves in a vertical direction, the crank arm provides torsion to the torsion element which acts as a spring for the vehicle suspension. By substantially mounting the entire suspension system directly below the vehicle frame rails, increased space is available between the wheels for luggage, fuel and spare tire storage. The rear suspension package is substantially reduced in both size and weight.

    摘要翻译： 提供了一种车辆悬架系统，其包括适于枢转地连接到车辆的框架的拖臂。 轮组件安装到拖臂的第一端，并且扭转元件整体地安装在牵引臂内。 设置有一个曲柄臂，其具有一个安装在该扭转元件上的第一端和一个在垂直方向上基本固定的运动的第二端。 当牵引臂沿垂直方向移动时，曲柄臂向作为车辆悬架的弹簧的扭转元件提供扭转。 通过将整个悬架系统基本上安装在车架轨道的正下方，用于行李箱，燃料和备用轮胎存放的轮子之间可以增加空间。 后悬架包装在尺寸和重量上均大大减小。
