Embodiment Construction

[0029] figure 1 A schematic diagram of a planetary gear train 1 is shown as an embodiment of a planetary carrier according to the invention, wherein the planetary carrier is denoted by 2 . The planetary carrier 2 is connected in a rotationally fixed manner to a shaft 3 and has planetary gears 4 outside its longitudinal axis. The axes of rotation of the planet gears 4 are parallel to the longitudinal axis of the planet carrier 2 . The sun gear 5 and the ring gear 6 are coaxially and rotatably mounted on the planet gear carrier 2 or the shaft 3 , and the sun gear and the ring gear 6 are continuously meshed with the planet gear 4 . The planet carrier 2 has a first friction plate body 7 . These components can be combined by means of the second friction plate body 8 connected to the sun gear 5 . By means of the third friction disc body 9 connected to the sun gear 5 , the sun gear can be braked via the fourth friction disc body 10 fastened to the housing.

Abstract

A planet carrier ( 2 ) for a gearbox, especially an automatic or power shift gearbox, is provided, including at least one planet gear ( 4 ) which is connected to a sun gear and a rotor wheel. The planet carrier is embodied in two parts and is made in two bodies ( 11, 12 ) which are formed with a step-like shape and which are arranged one within the other. The internal diameter of the axially extending segments of the external body ( 11 ) is adapted to the external diameters of the internal body ( 12 ). The bodies are positioned in a precise manner in relation to each other during construction. The individual components can be produced in a simple manner by shaping the sheet steel in a non-cutting manner.

Description

technical field [0001] The present invention relates to a planetary carrier for a transmission, especially for an automatic transmission or a power shift transmission, wherein the planetary gears are mounted on pins arranged coaxially with the center line of the planetary carrier The sun gear meshes with the ring gear. In addition, the planetary carrier has a lining body for a clutch lining or a brake lining. Background technique [0002] Prior art planetary gear trains are mainly used in automatic transmissions and power shift transmissions. The planetary gear train includes a central sun gear, a ring gear arranged coaxially with the sun gear, and a plurality of planetary gears arranged between the sun gear and the ring gear. The axes of rotation of these planet gears are parallel but aligned with the axes of rotation of the sun gear and the ring gear, wherein the teeth of the planet gears mesh continuously with the teeth of the sun gear or the ring gear. The planetary g...
