Abstract
A multispeed gear transmission having an internal gear driving an output shaft. The internal gear is in constant mesh with a plurality of drive pinions. Each drive pinion is connected to a fluid actuated clutch. The driving members of the clutches are driven by respective gears in constant mesh with each other or with a common input gear. Auxiliary output shafts may be driven by a gear meshed with the internal gear or by one of the drive pinions.
Claims9
A constant mesh gear transmission comprising:
- a housing;
- an input shaft having an input gear mounted thereon;
