摘要： A sub-frame assembly for use with a vehicle having wheels such as a trailer is provided. The sub-frame assembly comprises two or more frame members, one or more cross members, and two or more stub torsion axle assemblies. Each of the stub torsion axle assemblies have a torsion arm, a spindle extending from the torsion arm for mounting one of the wheels, and a distal end extending from the stub torsion axle assembly for mounting to the frame assembly. The frame assembly may further comprise one or more shim plates for reception between the cross member and the distal end of the stub torsion axle assembly for allowing adjustment of the toe angle of the wheel assembly. In addition, the stub torsion axle assembly may be rotatably mounted to the cross member whereby the camber angle of the wheel assembly may be adjusted.

摘要： A torsion axle arrangement is provided wherein the spindle is mounted to the suspension link by a keyed connection facilitated with a selectively orientable disc then fixed to the suspension link according to a given application. That connection is maintained by a bolt passing through the suspension link and engaging a mating groove in the spindle. The bolt is anchored within the suspension link by a threaded connection internal to the suspension link. The shape of the key can be selected as desired for immediate source identification.
摘要翻译：提供了一种扭转轴装置，其中主轴通过与可选择性定向盘协调的键控连接安装到悬挂连杆，然后根据给定的应用将该主轴固定到悬挂连杆。该连接通过穿过悬挂连杆并且与主轴中的配合凹槽接合的螺栓来维持。螺栓通过悬挂连杆内部的螺纹连接锚固在悬挂连杆内。可以根据需要选择密钥的形状，以便立即进行源识别。

摘要： A multi-axle leaf spring suspension having a compliant equalizer. The leaf springs are mounted one behind the other on each side of the vehicle. Adjacent ends of the leaf springs are pivotally attached to the compliant equalizer. The compliant equalizer is pivotally mounted to a vehicle frame. The compliant equalizer comprises a pair of arms that are pivotally connected to each other in a scissor-like fashion. One end of each arm is pivotally connected to the end of a leaf spring. The other end of each arm is cooperatively arranged to contain and compress a spring member between them. The compliant equalizer reduces the magnitude of shocks that would be other wise transmitted to the suspension and frame by absorbing them through compression of the spring member.
