The invention discloses a wheel centering device and a centering method for vehicle testing, comprising a dynamometer, a positioning mechanism and a controller, the dynamometer and the positioning mechanism are respectively electrically connected to the controller; the dynamometer There are four dynamometers, and the relative positions of the four dynamometers match the relative positions of the four wheels of the vehicle respectively; the central axis of the hub of the dynamometer is located below the ground, and the top of the hub is located above the ground; the positioning mechanism is provided with 4, and the 4 positioning mechanisms are respectively located outside the rotating hubs of the 4 dynamometers; the positioning mechanism includes a laser transceiver assembly and a shading assembly, and the laser transceiver assembly is installed on the rotating hub The outer side of the hub is located on the central axis of the rotating hub, and the shading assembly is installed at the center of the vehicle hub. Compared with the prior art, the centering device of the present invention has simpler structure and more accurate positioning.
Description
technical field [0001] The invention belongs to the technical field of vehicle testing, in particular to a wheel centering device and a centering method for vehicle testing. Background technique [0002] In the process of vehicle performance testing, a chassis dynamometer is often used, and a vehicle centering mechanism is arranged on the chassis dynamometer, which is mainly used to adjust the driving wheel of the vehicle to be tested to the center position of the rotating hub. The vehicle centering mechanism on the existing chassis dynamometer is usually equipped with four sets of ball screw lifts and four frequency conversion motors connected to them symmetrically on both sides of the dynamometer upper frame. The end of each set of ball screw lifts Connect a centering roller, start four frequency conversion motors, and each motor drives its corresponding ball screw lifter to make the corresponding centering roller roll, thereby driving the tires of the vehicle to be tested...
