Embodiment Construction

[0023] figure 1 A schematic diagram of a planetary gear train 1 is shown as an example of using the teaching according to the invention, wherein the planetary gear carrier is denoted by 2 . The planet carrier 2 is connected in a rotationally fixed manner to a shaft 3 and is provided with planet 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 planetary gear carrier 2 is provided with a first friction plate body 7 . These components can be coupled to one another via the second disk body 8 connected to the sun gear 5 . By means of the third disk body 9 connected to the sun gear 5 , the sun gear can be braked via the fourth disk body 10 fixed to the housing.

Abstract

A planet carrier ( 2 ) for a gearbox is provided, especially for an automatic transmission or a power-shift gearbox. The planet carrier ( 2 ) includes at least one planet gear ( 4 ) that is in constant contact with a sun gear and an internal geared wheel. The planet carrier ( 2 ) is formed from two parts and includes a single piece flange part ( 11 ) and a single piece cup body ( 12 ) formed in a step-type manner. The two components are rotationally symmetrical or approximately rotationally symmetrical, and are arranged with one at least partially inside the other. The internal diameter of the external part is adapted to the internal diameter of the internal part in an overlapping area. The two components are connected together at contact points. The components are positioned in a precise manner in relation to each other in the axial, radial and peripheral directions based on the construction. The individual components can be produced in a simple and economical manner through deep drawing.

Description

technical field [0001] The present invention relates to a planetary gear carrier for a transmission, especially for an automatic transmission or a power shift transmission, wherein planetary gears are mounted on pins, the planetary gears being aligned with the center line of the planetary gear carrier Shaft set sun gear meshing with ring gear. In addition, the planetary carrier is provided with 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 the 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 gea...
