Multiple speed automotive transmission |
摘要 |
A multiple speed transmission producing a gear ratio in response to movement of a gear selector lever and manipulation of a clutch pedal includes three planetary gearsets each including a sun gear, ring gear, carrier rotatably supporting a set of planet pinions in continues meshing engagement with the corresponding sun gear and ring gear, and a brake drum driveably connected to one component of each gearset and adapted for alternate engagement by a brake band. The brake band is biased into engagement with the corresponding brake drum by a spring and is released from that engagement using a clutch pedal. A shift lever moves the band to the gearset that produces the desired gear ratio. Engagement of the brake band with each of the drums holds a component of the gearset against rotation on the transmission housing.
