Abstract: A test stand (100) for testing properties of an electrically drivable axle module (10) for a motor vehicle has at least one loading unit and at least one test object support (110) with a mechanical interface (120) for clamping the axle module (10), an electric interface (141) for energizing the axle module (10), a sensor interface (143) for contacting sensors of the axle module (10), and a fluid interface (142) for supplying fluid to the axle module (10). The mechanical interface (120) is designed as an interchangeable test object receiving area (120) onto which the axle module (10) is deposited over defined contact points (11).

Abstract: The invention relates to a method for marking a vehicle tyre (20) and a corresponding marking station. In one example, the vehicle tyre is supplied (100) to a marking station (10), the vehicle tyre (20) is aligned and centred (102, 103) in the marking station (10), marking is performed (108) in the marking station in accordance with characteristics of the vehicle tyre (20), and marking is performed (108) using one marking device (12) from a multiplicity of different marking devices (12). The method according to the invention is distinguished by the fact that the marking device (12) for marking the vehicle tyre (20) is positioned (107) at the vehicle tyre (20) by means of a robot arm (11).

Abstract: The invention relates to a test stand (100) for a powertrain of a motor vehicle (20). The test stand includes at least one loading motor (110) with a motor housing (111) and a motor shaft (112), at least one torque sensor (120), and at least one static module (130), wherein the motor shaft (112) is designed to be drivingly connected to a hub (21) of the motor vehicle (20) and wherein the torque sensor (120) is designed to detect a torque produced by the loading motor (110). The test stand (100) according to the invention is distinguished in that the at least one torque sensor (120) is arranged on the motor housing (111) in such manner that it blocks a rotation movement of the motor housing (111) relative to a substrate (119) and supports the torque via the motor housing (111) on the substrate (119).

Abstract: A revolving drum arrangement (2) for a tire testing rig (1) has a drum body (5) and a friction wheel drive (6), wherein on its outer circumference (9) the drum body (5) has a running surface (9) for making contact with a vehicle tire (4) and is arranged to rotate about its running axle. The friction wheel drive (6) is designed to drive the drum body (5) when it is in contact with the drum body (5). The revolving drum arrangement (2) according to the invention is distinguished in that the friction wheel drive (6) is arranged on a friction wheel carriage (10) that is designed to move the friction wheel drive (6) along an infeed direction so that the friction wheel drive (6) can be brought into contact with the drum body (5). A corresponding tire testing rig (1) and method are also disclosed.

Abstract: A test stand for a powertrain of a motor vehicle includes at least one loading motor with a motor housing and a motor shaft, at least one load sensor, and at least one positioning module. The motor shaft is configured to be drivingly connected to a hub of the motor vehicle and the load sensor is configured to detect a load transmitted from the motor shaft to the hub. An axial side of the motor housing facing toward the hub is connected rotationally fixed to the at least one positioning module. The motor shaft can be hollow, where a shaft inserted through the hollow shaft can be connected rotationally fixed directly or indirectly to the hub. The load sensor is on an axial side of the motor housing facing away from the hub, and the hollow shaft can be drivingly connected to the shaft by way of the load sensor.
