  • Patent number: 10035512
    Abstract: The present invention is capable of suppressing gear shift shocks or delays in acceleration with no interruption of driving force and reducing the weight. Disclosed is a transmission which is provided with multiple stage shift gears so arranged to shift a number of dog clutches to shift a gear to the upper stage of the multiple stage shift gears, and is characterized in that a guide part is provided to a shift operation section and the dog clutches on each of the sages so as to move the lower dog clutch in a neutral direction by a coasting torque acting on the lower stage by a shift rotation of the upper stage to release a meshing engagement when meshing engagements of the lower and upper dog clutches are simultaneously performed by an operation of the shift operation section.

  • Patent number: 7318360
    Abstract: A handling mechanism of a gearshift which enable to shift endlessly into neutral, first-speed, second-speed, third-speed, fourth-speed, fifth-speed, neutral, first-speed, second-speed, third-speed, fourth-speed, fifth-speed for example can be used for the wire-typed and lot-typed transmission. The gearshift handling mechanism can be shifted endlessly and mechanically into neutral, first-speed, second-speed, third-speed, fourth-speed, fifth-speed, neutral, first-speed, second-speed, third-speed, fourth-speed, fifth-speed for example via the operation lever which is moved in the forward-backward direction.

  • Publication number: 20030047020
    Abstract: A handling mechanism of a gearshift comprises a gearshift provided at a shift fork of an handling mechanism of a manual transmission, projecting from a box of the handling mechanism slightly; a moving mechanism for the gearshift allowing it to move along a H-shaped line substantially, having a mechanism for right-left removing cam allowing to move to the right and left directions and a forward-backward removing link allowing to move forward and backward directions; an handling mechanism allowing the gearshift to shift into reverse, neutral, first-speed, second-speed, third-speed and fourth-speed in order due to allow to operate the link and moving cam mechanism by operating a shift lever to the forward and backward directions, so that the gears can be certainly changed in a shift up, a shift down, a neutral, or the reverse due to only sufficient operation by an operation lever to the forward-backward direction. Moreover, the gear can be changed certainly when it becomes familiar with.
