Patent number: 10788125Abstract: A first dog ring and a second dog ring are biased toward each other by means of springs. When the first dog ring and the second dog ring are moved away from each other, bias force produced by the springs is applied to the second dog ring in a direction to draw the second dog ring toward the first dog ring. Accordingly, when the first dog ring is moved away from the second dog ring during shifting, the second dog ring is drawn toward the first dog ring under the bias force, and third engaging teeth of the second dog ring and meshing teeth of a first-speed gear are promptly disengaged from each other.Type: GrantFiled: September 14, 2017Date of Patent: September 29, 2020Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, TOYOTA MOTORSPORT GmbHInventors: Shinichi Takeuchi, Akihiko Ichikawa, Junichi Muraoka, Kotaro Hoshihara, Tomohiro Yoshimura, Jun Yabuta, Klemens Pollmeier, Lars Van Leeuwen, Andree Miller
