ABSTRACT:
A vehicle transmission includes a planetary gearing having two sets of planets, one of which being of the stepped type with different diameters at opposite ends of the planets. Input is by way of the stepped planets and output is transferred by way of the other planets. A planet carrier for the stepped planets carries a sun wheel cooperating with the other planets, and is formed into a clutch housing having first and second compartments. The planet carrier for the other planets is provided with a clutch member, and a brake member, the former of which is adapted for cooperation with the second compartment of the clutch housing, while the other is adapted to engage the stationary casing enclosing the gearing. A ring gear cooperating with the stepped planets carries a clutch member adapted for engagement with the first compartment of the clutch housing. A sun wheel on a lay-shaft engages one of the stepped planets and supports a brake member adapted to engage a stationary portion of the gear casing. The clutch and brake members are selectively engageable for providing three gear steps while driving forward as well as in reverse.
