    • Traction and/or friction testing apparatus is described having inter-engaging, rotating, traction surfaces, the surfaces being independently driven to generate traction or friction forces therebetween. A force measuring means is provided to measure the resulting traction or friction force. The apparatus is characterised in that all forces applying in the traction measurement loop are directly readable, or elastic, thus eliminating internal friction and allowing an accurate indication of the traction or friction force. The apparatus is particularly useful for measuring rolling/sliding traction and friction.
    • 牵引和/或摩擦测试装置被描述为具有相互接合的,旋转的牵引表面,所述表面被独立地驱动以在它们之间产生牵引力或摩擦力。 提供力测量装置以测量所得到的牵引力或摩擦力。 该装置的特征在于,在牵引测量回路中施加的所有力都是直接可读或弹性的,从而消除内部摩擦并允许对牵引力或摩擦力的精确指示。 该装置对于测量滚动/滑动牵引力和摩擦力特别有用。
