摘要：针对斜撑式超越离合器高速楔合容易产生故障的实际情况，对其楔合动态过程进行研究。工作过程中，斜撑式超越离合器内部楔块之间、楔块与内外环间以及各部件同保持架间存在碰撞。首先基于Hertz接触理论，求解了碰撞刚度，为明确各参数对高速斜撑超越离合器动态响应的影响程度，建立了包括楔合延迟时间、冲击力矩、最大转速差等在内的评价指标。同时，将高速斜撑超越离合器的楔合动态过程进行划分，以研究几何参数对不同响应阶段的影响。最后，开展了楔块与内环的摩擦条件、弹簧力、碰撞刚度、阻尼和负载等对高速斜撑超越离合器楔合动态响应的研究。结果表明，不同参数对所定义的评价指标的影响程度不同，极端情况下可导致楔合失败。该研究可为工程实践提供一定的理论参考和指导。

Abstract：Aiming at the actual situation that the high-speed wedging of the oblique overrunning clutch is prone to failures, this paper studies the dynamic process of its wedging. During the working process, there are collisions between the internal wedges, between the wedges and the inner and outer rings, and between the components and the cage. Firstly, the collision stiffness is solved based on the Hertz contact theory. Then the evaluation indexes are established, including the wedging delay time, impact torque, maximum speed difference, etc., to determine the degree of influence of the dynamic response of the overrunning clutch. At the same time, the wedging dynamic process of the high-speed overrunning clutch is divided to study the influence of the geometric parameters on different response stages. Finally, the friction conditions between the wedge and the inner ring, spring force, collision stiffness, damping and load are studied on the dynamic response of the high-speed oblique overrunning clutch. The results show that different parameters have different degrees of influence on the defined evaluation indicators, which can lead to wedging failure in extreme cases.
Key words：high-speed oblique overrunning clutch；wedging process；dynamic response
