| 摘要 |
The invention relates to a transmission drive device (10) comprising a shaft (14; 14a) which is arranged in a housing (12) in a longitudinally movable manner in the direction of the shaft axis (26) and comprising a shaft end (15; 15a) which is formed on an end face and which is supported at least indirectly on the housing (12) via at least one starting element (30). Either the shaft end (15) or the starting element (30) has a rounded design at least in some regions, a bearing point (31) being formed between the starting element (30) and the shaft end (15; 15a), and the starting element (30) being coupled to a damping element (32; 32a to 32d) which allows a movement of the starting element (30) in the event of an axial application of force (FA, FA1, FA2) by means of the shaft (14; 14a). According to the invention, the starting element (30) and/or the damping element (32; 32a to 32d) is/are designed and/or arranged such that the distance (r) of the bearing point (31) to the longitudinal axis (26) of the shaft (14; 14a) increases as the axial application of force (FA, FA1, FA2) increases at least starting from a specified level of the application of force (FA, FA1, FA2). |
