WHEEL END WITH MONITORING CAPABILITIES

摘要

An automotive vehicle has road wheels that are coupled to suspension uprights of the vehicle through wheel ends that have the capacity to monitor lateral loads that act on the road wheels at tire patches where the road wheels contact a road surface. Each wheel end offsets displacements that would be produced within the wheel end by vertical loads with displacements that would be produced by moments induced by the vertical loads, so that the remaining displacements within the wheel end reflect essentially lateral loads exerted at the tire patch. The wheel end contains a sensor and a target that the sensor monitors to detect the presence and magnitude of the displacements and hence the magnitude and direction of the lateral force at the tire patch. The sensor may also monitor angular velocity, angular position, and temperature.
