Abstract

A driven hatch arrangement is provided, particularly a rear hatch arrangement, for a motor vehicle with a hatch and with a hatch drive for opening and/or closing the hatch, with the hatch drive comprising a motor with a motor shaft and a motor pinion and at least one planetary gear with a sun gear, planetary carriers with planetary rolling elements arranged on bearing pins, and an annulus, with the sun wheel of the planetary gear being formed by the motor pinion and a driven shaft being driven via the planetary gear, in which the motor pinion is slid onto the motor shaft.

First claim

We claim:

1. A driven hatch arrangement, comprising a rear hatch arrangement for a motor vehicle with a hatch and with a hatch drive for opening and closing the hatch, with the hatch drive comprising a motor with a motor shaft and a motor pinion and at least one planetary drive with a sun gear, planetary carriers with planetary rolling elements arranged on bearing pins, and an annulus, with the sun gear of the planetary drive being formed by the motor pinion and with a driven shaft being driven by the planetary drive, wherein the motor pinion is slid onto the motor shaft, and wherein the driven shaft is formed in one piece with the planetary carrier including bearing pins for the planetary rolling elements.

2. The driven hatch arrangement of claim 1 , wherein the motor pinion is displaceably arranged in the axial direction of the motor shaft.

3. The driven hatch arrangement of claim 2 , wherein the ability of displacement of the motor pinion in the axial direction of the motor shaft is limited by a stop in the direction towards a housing of the motor and/or in the direction towards the planetary carrier of the planetary gear.

4. The driven hatch arrangement of claim 1 , wherein the motor pinion is a plastic pinion.

5. The driven hatch arrangement of claim 1 , wherein the motor pinion comprises helical gears.

6. The driven hatch arrangement of claim 1 , wherein the driven shaft is formed in one piece including the planetary carrier and the bearing pins for the planetary rolling elements are produced in a molding process and made from plastic or produced by metal injection molding or ceramic injection processes.

7. The driven hatch arrangement of claim 1 , wherein the bearing pins of the planetary carrier projects in the direction towards the motor beyond planetary rolling elements arranged on the bearing pins.

8. The driven hatch arrangement of claim 1 , wherein the motor pinion is secured by a form-fitting connection to at least a section of the motor shaft against a radial distortion in reference to the motor shaft.
