<p>PURPOSE: To provide a multiple disc frictional engaging device of which heat capacity absorbing friction heat is improved. CONSTITUTION: A multiple disc frictional engaging device is constituted so that alternately arranged external gear plates 53, 54, 55 and internal gear plates 56, 57 are engaged with each other through friction material 62 so as to transmit torque, the friction material 62 is fixedly secured to the one-sided faces of the core plates 74 of the external gear plates 54 except the external gear plates 53, 55 potitioned on the beginning and the end of arrangement, both side faces of the core plate 76 of the internal gear plate 56 positioned on the beginning of arrangement, and the one-sided faces of the core plates of the remaining internal gear plates 57. Friction heat is absorbed by the external gear plates 53, 55 and the core plates 74, 77 contacted with the friction plates, and the friction heat is released from the back of the external gear plates 53, 55. Hereby, heat capacity of the multiple disc frictional engaging device 50 is improved.</p> |
