Publication number: 20040069085Abstract: A vibration-proof structure for a gear transmission device includes a wave washer for pressing a gear of a gear transmission device that can move in an axial direction between opposed first and second fixed walls toward the first fixed wall. The wave washer is interposed between the gear and the second fixed wall. A cylindrical portion surrounding the wave washer is provided between one of the opposed end faces of the gear and the second fixed wall, and the cylindrical portion is in contact with the other end face to regulate an increase in the bending amount of the wave washer of a predetermined value. When the gear of the gear transmission device experiences vibration, the excessive bending of the wave washer for absorbing the vibration is restrained so that the wave washer can always exhibit a normal buffering function.Type: ApplicationFiled: August 25, 2003Publication date: April 15, 2004Inventors: Kenichiro Nakamura, Satoshi Fujikawa, Akira Sonobata, Shunsuke Iwai

Patent number: 4920828Abstract: A transmission is equipped with a planetary gear type transmission unit disposed between an input member and an output member within a casing. The transmission unit is comprised of a sun gear, a ring gear and a plurality of planet gears carried by a carrier coupled with the output member. The planet gears are in mesh with the sun gear and the ring gear. The input and output members are coupled with each other by bypassing the gears of the transmission unit in direct drive or via these gears in reduction ratio drive. The transmission is further provided with a first change-over member in mesh with the input member for selectively connecting the input member with the carrier in direct drive or with the sun gear in reduction ratio drive and a second change-over member secured to the first change-over member for engaging the ring gear with the casing in reduction ratio drive or disengaging the former from the latter in direct drive.Type: GrantFiled: February 7, 1989Date of Patent: May 1, 1990Assignee: Mazda Motor CorporationInventors: Osamu Kameda, Satoshi Fujikawa, Toshiharu Shinmoto

Patent number: 4846010Abstract: A transfer case operation mode shifting apparatus is actuated by an electric actuator including an electric motor and a differential power transmitting mechanism which transmits a driving power for axially moving a differential gear shift member to shift a center-differential gear assembly between a four-wheel and a two-wheel drive mode of operation. The driving power transmitted by the differential power transmitting mechanism and acting on the differential gear shift means is smaller when shifting the center-differential gear assembly from the four-wheel to the two-wheel drive mode of operation than when shifting back the center-differential gear assembly from the two-wheel to the four-wheel drive mode of operation.Type: GrantFiled: July 29, 1988Date of Patent: July 11, 1989Assignee: Mazda Motor CorporationInventors: Satoshi Fujikawa, Hideshi Hiruta
