The invention relates to a steering gear (1) for a steer-by-wire steering device for a vehicle and with a steering rod (4), wherein the steering rod (4) is connected to an electric drive (2) by means of a transmission device (3). In order to be able to better detect the forces acting on the steering rod (4), the steering gear (1) is characterized in that a bearing device (12) is arranged between the steering rod housing (11) and a steering rod portion (13) of the steering rod (4), wherein the bearing device (12) is fixedly attached or held on the steering rod housing (11), and the steering rod portion (13) and the bearing device (12) engage with one another in such a way that a rotational movement of the steering rod (4) is blocked and a translational displacement of the steering rod (4) in the axial direction of the central longitudinal axis (5) of the steering rod (4) is allowed, wherein a sensor device (29) for determining a torque of the steering rod (4) about the central longitudinal axis (5) of the steering rod (4) is arranged in the region of the bearing device (12).
A steering gear for a steer-by-wire steering device and with a steering rod (4), wherein the steering rod (4) is connected to an electric drive (2) by means of a transmission device (3), and the transmission device (3) is designed to convert a rotational movement of the electric drive (2) into a translational movement of the steering rod (4) in the axial direction of a central longitudinal axis (5) of the steering rod (4), and with a steering rod housing (11) in which the steering rod (4) is partially arranged, wherein a bearing device (12) is arranged between the steering rod housing (11) and a steering rod portion (13) of the steering rod (4), wherein the bearing device (12) is fixedly attached or held on the steering rod housing (11), and the steering rod portion (13) and the bearing device (12) engage in one another in such a way that a rotational movement of the steering rod (4) is blocked and a translational displacement of the steering rod (4) in the axial direction of the central longitudinal axis (5) of the steering rod (4) is allowed, wherein a sensor device (29) for determining a force and/or a torque of the steering rod (4) about the central longitudinal axis (5) of the steering rod (4) is arranged in the region of the bearing device (12).
