摘要： A suspension system for the rear wheels of a motor vehicle includes a pair of leaf springs having their fore and aft ends pivotally mounted to the vehicle frame or body. The leaf springs flexibly support a tubular rear axle member forwardly and downwardly offset from the rear wheel spindles by a pair of left and right one-piece castings. Each casting has an outboard spindle mounting L-shaped angle portion and an inboard forwardly and downwardly offset collar portion joined by a canted bridging portion. The collars each receive one end of the tubular axle member. The casting include a jounce deflection stop-plate for engaging its associated frame bumper. Leaf springs are seated on each casting below the spindle axis and above the tubular axle member reducing the design height of the vehicle. The tubular axle portion and spindles are constrained to move equal distances during upward jounce deflection.
摘要翻译：用于机动车辆的后轮的悬挂系统包括一对板簧，其前端和后端枢转地安装在车架或车身上。板簧通过一对左右一体式铸件弹性地支撑管状后桥构件向前和向下偏离后轮主轴。每个铸件具有外侧主轴安装L形角部分和由倾斜桥接部分连接的内侧向前和向下偏移的轴环部分。套环各自容纳管状轴构件的一端。该铸件包括用于接合其相关联的框架保险杠的翘曲偏转止动板。板簧位于主轴轴心下方的每个铸件上，并且在管状轴构件的上方，减小了车辆的设计高度。在向上弯曲偏转期间，管状轴部分和主轴被限制为移动相等的距离。

摘要： An improved vehicle load sensing mechanism for a brake proportioning system including a suspension spring follower lever. The follower lever is mounted co-axially with a leaf-type spring mounting fastener and utilizes a low-friction sleeved bearing assembly to thereby exactly duplicate pivotal movements of the spring end caused by road irregularities without creating significant force levels between portions of the lever and the end of the spring.

摘要： An improved brake proportioning system, particularly for a vehicle such as a truck, subject to relatively large differences in loading, includes a force responsive proportioning valve inserted between a master brake cylinder and the rear brakes of the vehicle for increasing the rear braking effort relative to the front braking effort as the vehicle load increases. A device which senses the position of the rear spring of the vehicle operably connected to the force input of the proportioning valve by responding to angular movements of the pivotally mounted end portion of the rear leaf spring whereby spring flexure due to changes in vehicle load produce a corresponding input force to the proportioning valve.
摘要翻译：改进的制动比例系统，特别是用于诸如卡车的车辆，承受相对较大的负载差异，包括插入在主制动缸和车辆的后制动器之间的力响应比例阀，以增加相对于车辆负载增加时的前制动力。通过响应于后板簧的可枢转地安装的端部的角运动来感测车辆的后弹簧的位置的装置，其可操作地连接到比例阀的力输入，由此由于车辆负载的变化而产生弹簧挠曲相应的输入力到比例阀。

摘要： An improved braking system, particularly for a vehicle such as a truck, subject to relatively large differences in loading, including a force responsive proportioning valve inserted between a master brake cylinder and the rear brakes for increasing the rear braking effort relative to the front as the load on the vehicle increases. A spring position follower device is operably connected to the force input of the proportioning valve to respond to angular movements of the pivotally mounted end portion of the rear leaf spring whereby an increased input force is transmitted to the proportioning valve as the spring flexes due to vehicle load increases.
