TORQUE LIMITER FOR HYBRID VEHICLE

摘要

PURPOSE: A torque limiter for a hybrid vehicle is provided to secure responsiveness in a high-torque area and NVH performance in a low-torque area by phasing the rigidity of a damper spring according to the rotational displacement. CONSTITUTION: A torque limiter for a hybrid vehicle comprises a torsional damper. The torsional damper comprises a plurality of damper spring assemblies(16). A damper spring assembly is arranged in between a drive plate and a driven plate and comprises first and second rigidity damper springs(30,32). The first rigidity damper spring comprises a large diameter coil spring. The second rigidity damper spring comprises a small diameter coil spring. The second rigidity damper spring is formed with a smaller free length than the first rigidity damper to be inserted into the first rigidity damper spring.
