摘　　要：提出一种新型张环式超越离合器,其自锁构件呈环状,与输出构件成低副面接触,与传统的高副式超越离合器相比承载能力有所提高。对该张环式超越离合器自锁及超越条件进行分析,并研究了其自锁条件对滚柱磨损的敏感性,研究表明,在该项性能上该超越离合器优于滚柱式超越离合器。最后对新型张环式超越离合器进行了仿真及实验验证。A new expanding-ring type overrunning clutch was proposed, its self-locking compo- nent was a ring which was in a lower pair face contact with the output members and whose carrying capacity was improved compared with conventional higher pair type overrunning clutchs. The self-loc- king and overrunning conditions were analyzed and the self-locking conditions on the pin roller wear sensitivity were studied. Theoretical study shows that the clutch performance is superior to the pin roller type overrunning clutchs. Finally, the simulation and experimental verification of a new type of tension ring clutch were carried out.
