提出了一种弧面接触复位止挡重载车钩的创新结构。该联轴器在小偏航角下具有小的横向力，并且偏航角是有限的，以确保在强压缩力下允许的联轴器横向力。组合式接触联轴器的主要结构特点是具有0.06-0.08的适当摩擦系数的横向可动从动件和纵向运动单自由度的滑块。为了验证和仿真该系统的性能，建立了包含4台重载机车和3个细节车钩的多体动力学模型，对紧急制动过程进行了仿真。此外，还进行了车钩横摆不稳定性和轮对横向力试验，研究了相关参数对车钩性能的影响。组合式车钩具有良好的动力学性能，适用于重载列车。
An innovative structure for a heavy haul coupler with an arc surface contact and restoring bumpstop is proposed. This coupler has a small lateral force at a small yaw angle and a limitable yaw angle to ensure an allowable coupler lateral force under intense compressive force. The main structural characteristic of the combined contact coupler is a lateral movable follower with an appropriate friction coefficient of 0.06–0.08 and a slide block with a single freedom of longitudinal movement. In order to verify and simulate the performances, a multi-body dynamics model with four heavy haul locomotives and three detailed couplers was established to simulate the process of emergency braking. In addition, the coupler yaw instability and wheel set lateral forces were tested in order to investigate the effect of relevant parameters on the coupler performances. The combined contact coupler is suitable for heavy haul train for a good dynamic performance.
