Problems solved by technology

However, the mechanical interfaces required for this between the transmission input shaft and the steering spindle and between the transmission input shaft and the transmission output shaft are limited by the complex geometry and the high demands on the material strength of the transmission input shaft. Causes high manufacturing outlay, which likewise leads to high manufacturing costs

Embodiment Construction

[0031] figure 1 A schematic diagram of a steering transmission mechanism for a steering system of a motor vehicle according to a preferred embodiment of the present invention is shown.

[0032] The steering transmission mechanism 1 for a steering system of a motor vehicle has a transmission mechanism input shaft 10 and a transmission mechanism output shaft 12. The transmission mechanism input shaft 10 can be connected to (at the first axial end section 10a) figure 1 (Shown schematically in) the steering spindle 14 is connected. In addition, the transmission mechanism input shaft 10 is connected to the transmission mechanism output shaft 12 at the second axial end section 10b in the assembled state.

[0033] The transmission mechanism input shaft 10 has an external tooth portion 10c continuously configured along the axial direction A. The external tooth portion 10c is configured to transmit the torque applied to the transmission mechanism input shaft 10 by the steering spindle 14 t...

Abstract

The invention relates to a steering transmission mechanism (1) for the steering system of a motor vehicle. The steering transmission mechanism comprises a transmission mechanism input shaft (10) and atransmission mechanism output shaft (12). The transmission mechanism input shaft (10) is connected to a steering main shaft (14) in a first axial end section (10a) and is connected to the transmission mechanism output shaft (12) in a second axial end section (10b). The transmission mechanism input shaft (10) is provided with an external tooth part (10c) that is continuously constructed in the axial direction (A). The external tooth part is configured to transmit the torque applied on the transmission mechanism input shaft (10) by the steering main shaft (14) to the transmission mechanism output shaft (12).

Description

Technical field [0001] The invention relates to a steering transmission mechanism for a steering system of a motor vehicle. Background technique [0002] In particular, electric, hydraulic or electro-hydraulic steering supports for commercial vehicles usually have a transmission mechanism input shaft and a transmission mechanism output shaft. These servo steering mechanisms convert the rotational motion of the steering spindle into linear motion, which can be amplified in an electrical and / or hydraulic manner, for example. In this case, the transmission mechanism input shaft can be connected to the steering spindle at a first axial end section and to the transmission mechanism output shaft at a second axial end section . [0003] In addition, the torsion bar is usually arranged in a cavity constructed in the input shaft of the transmission mechanism, the torsion bar connects the transmission mechanism input shaft with the transmission mechanism output shaft and enables the transm...
