IPC: F16D65/12
Filed: 1990-11-29
Abstract: PURPOSE:To restrict performance drop in a frictional member caused by thermal degradation and realize the downsizing by arranging a circular arc shape frictional plate carrying out spline engagement with the housing side and a circular shape mating plate carrying out spline engagement with the drum side alternately in the shaft direction. CONSTITUTION:A circular arc shape frictional plate 21 carrying out spline engagement with the housing 13 side and a circular shape mating plate 22 carrying out spline engagement with the drum 12 side are arranged alternately in the axial direction. When heat is generated on the frictional engagement surface due to repetition of frictional engagement, the generated heat is transmitted to the frictional plate 21 and the mating plate 22. By the way, the torque transmitting surface is a circular arc shape, and meanwhile, the mating plate 22 is a circular shape. Accordingly, the mating plate 22 is never engaged with a frictional member except the frictional engagement surface, and thereby, the mating plate 22 is cooled in a part except the frictional engagement surface. Furthermore, the heat transmitted to the frictional plate 21 can be emanated through the mating plate 22 once cooled.
