Embodiment Construction

[0029] figure 1 A schematic diagram of a vehicle 100 with an electromechanical steering system 110 according to one embodiment is shown. The vehicle 100 is a motor vehicle, in particular a commercial vehicle, eg a truck or the like. Steering system 110 has a steering column 114 and a steering rocker arm 116 . The steering column 114 is connected to the steering wheel 112 . Steering wheel 112 may also be part of steering system 110 . The steering rocker arm 116 is coupled to a steerable wheel of, for example, one axle of the vehicle 100 by suitable means. Furthermore, the steering system 110 has a steering gear 120 . The steering gear 120 is embodied as an electromechanical steering gear or with an electromechanical drive. The steering column 114 and the steering rocker arm 116 are connected to each other by means of the steering gear 120 or via the steering gear 120 . here, figure 1 Also shown are the input shaft 121 and the segment shaft 122 of the steering gear 120 . ...

Abstract

The invention relates to a steering gear (120) for an electromechanical steering system of a vehicle. The steering gear (120) has an input shaft (122) which can or has been coupled to a steering column of the steering system, a section shaft (121) which can or has been coupled to a steering rocker arm of the steering system, an angle gear (240), a servo gear (250) and an electric motor (230) for driving the servo gear (250). The angle gear (240) is designed as a bevel gear. The input shaft (121) and the electric motor (230) are connected to the servo transmission (250). And the servo transmission device (250) is connected with the angle transmission device (240). The angle transmission device (240) is connected to the section shaft (122). The angle transmission device (240) is designed to transmit a torque from the servo transmission device (250) to the section shaft (122) via two transmission paths.

Description

technical field [0001] The invention relates to a steering gear for an electromechanical steering system of a vehicle and to an electromechanical steering system for a vehicle, in particular a commercial vehicle. Background technique [0002] Servo steering systems that are part of a commercial vehicle steering system can often be implemented as a hydraulic system. Hydraulic systems can be disadvantageous in terms of energy efficiency, in which, in order to provide the steering force, a high volume flow must be pumped through the steering device at all times. Furthermore, functional extensions other than the actual steering functions, such as driver assistance systems, are more complex to implement. Furthermore, due to their separate installation sites between the steering pump and the steering transmission, lines may be required that must be installed, filled and checked during vehicle assembly. SUMMARY OF THE INVENTION [0003] Against this background, the object of th...
