    • A trailer hitch system may include a scale ball mount for supporting a hitch ball as part of a trailer hitch system, and for measuring the tongue weight of a trailer. The scale ball mount may comprise a trailer hitch ball mount. In an embodiment, the scale ball mount may include a biasing component disposed below a hitch ball, and a displacement gauge for displaying downward displacement of the hitch ball, and a scale reader for indicating the trailer tongue weight corresponding to the downward displacement. In another embodiment, the ball mount may include a plunger configured and dimensioned to contact a drop bar about which the ball mount rotates, the plunger in fluid communication with a dial for displaying a trailer tongue weight.
    • 挂车挂钩系统可包括用于支撑作为挂车挂钩系统的一部分的挂钩球并用于测量拖车的鞋舌重量的标尺球支架。 比例球支架可以包括拖车悬挂球支架。 在一个实施例中,比例球支架可以包括布置在拖车球下方的偏置部件和用于显示拖车球的向下位移的位移计以及用于指示对应于向下位移的拖车舌重的比例尺读取器。 在另一个实施例中,球座可以包括柱塞,该柱塞的构造和尺寸被设置为接触落球杆,落球杆围绕该落球杆旋转,柱塞与用于显示拖车榫舌重量的拨号盘流体连通。

    • Force measurement device for measuring the vertical force component (P) acting on a coupling (1) between a towing vehicle and a towed vehicle. The coupling includes two stiff holder plates (4, 6) and an intermediate sensor means (5) having at least one deflectable or pivotable sensor plate (10). The sensor plate (10) is deflected or pivoted under the action of a vertical force (P) by the holder plates (4, 6) being restrictedly, mutually pivotable, there being spacer means (8a, 8b, 9a, 9b, 9c) which are placed in staggered relationship between the sensor plate (10) and the respective holder plates (4, 6) on each side of the fastening means keeping the holder plates and the intermediate sensor means together. Transducer means are arranged on the deflectable or pivotable sensor plate (10) for sensing the deflection or pivoting and emitting an electrical signal corresponding to the vertical force (P).
    • 用于测量作用在牵引车和牵引车辆之间的联轴器(1)上的垂直力分量(P)的力测量装置。 联接器包括两个刚性保持板(4,6)和具有至少一个可偏转或可枢转的传感器板(10)的中间传感器装置(5)。 传感器板(10)在保持板(4,6)的作用下在垂直力(P)的作用下被限制地相互枢转地偏转或枢转,分隔装置(8a,8b,9a,9b,9c) 它们在传感器板(10)和紧固装置的每一侧上的各个保持板(4,6)之间以交错的关系放置,保持保持板和中间传感器装置在一起。 传感器装置布置在可偏转或可枢转的传感器板(10)上,用于感测偏转或枢转并发射对应于垂直力(P)的电信号。
