An apparatus for testing the brakes, wheel alignment, suspension, transmission, and engine of motorized wheeled vehicles, includes means such as a dynamometer for self-calibration. A platform supports a road vehicle to be tested. Two or four pairs of short high-inertia rollers are revolvably supported adjacent to said platform, and positioned to individually support either the front wheels or the back wheels of the vehicle. The rollers are drivable by a stationary vehicle resting thereon, each pair of high-inertia rollers supporting one vehicle wheel. A floating roller contacts the wheel to detect side forces. Sensor means are connected to the rollers and data processing, display and recording means are connected to the sensors. Speed of the rollers is monitored by an encoder having a resolution of at least 1000 pulses/sec. A preferred embodiment of the apparatus includes electric motors which can be connected to drive the rollers.
A vehicle testing apparatus, said apparatus comprising:
The testing apparatus as claimed in claim 6, wherein said floating roller is suspended to allow limited axial movement in response to side forces acting thereon when in contact with a revolving wheel of a vehicle, said floating roller further comprising a positioning sensor to measure said axial movement.
A vehicle testing method, comprising:
The method of claim 19, comprising positioning a sensor means associated with said one wheel of said vehicle, said sensor means to enable the measuring of said one wheel of said vehicle.
The method of claim 20, comprising providing a data processing means associated with said sensor means, said data processing means to enable testing of said one wheel of said vehicle.
The method of claim 22, wherein said calibrating comprises:
