Title: Forward/backward changeover device for continuously variable transmission
Inventor: SAKAI YASUTO
IPC: B60W10/10
Filed: 1986-09-12
Abstract: PURPOSE:To prevent the slipping of a belt, in a two-position changeover of a forward/backward changeover part, by providing a returning means by which the forward/backward changeover part is returned to the neutral position when an engine is stopped and line pressure is caused to disappear. CONSTITUTION:A forward/backward changeover part 3 is actuated by a changeover part 120 and a hydraulic servo 130 of a hydraulic actuator 116. In the forward/backward changeover part 3 a returning means 170 by which it is returned to the neutral position is provided, and the end of a returning lever 171 being rockably supported is lockedly engaged with a sleeve 29, and further springs 172, 173 are energized.
