Motorcycle dynamometer
First Claim
1. Dynamometer apparatus for measuring the performance of a wheeled vehicle comprising:
- support means on which said vehicle may be supported;
power absorption means mounted on said support means and including first roller means for frictional engagement with at least one wheel of said vehicle;
pressure means included with said power absorption means for producing a fluid pressure in response and proportional to the torque produced at said vehicle wheel;
speed means mounted on said support means and including second roller means for engagement with said vehicle wheel, independently of said first roller means for indicating the surface speed thereof; and
indicator means connected to said pressure means and said speed means for measuring said fluid pressure and said surface speed and including chart means on which horsepower curves are plotted for various speeds and pressure so that the horsepower of said motorcycle can be determined by entering the pressure and speed measured by said indicator means.

Abstract
Dynamometer apparatus for measuring the performance of a wheeled vehicle comprising: a support assembly on which the vehicle may be supported; power absorption apparatus mounted on the support assembly for engagement with at least one wheel of the vehicle; a pump connected to the power absorption apparatus for producing a fluid pressure in response to the torque produced by the vehicle wheel; speed measuring apparatus mounted on the support for engagement with the vehicle wheel to indicate the surface speed thereof; and indicator apparatus connected to the pump and the speed measuring apparatus for correlating fluid pressure and surface speed with the performance of the vehicle.

15. A method of determining horsepower developed by a motorcycle comprising the steps of:
-
placing the driven wheel of the motorcycle between a pair of independently mounted roller members for engagement therewith, one of said roller members being attached to a positive displacement pump; applying the power of the motorcycle to said one roller to operate said pump; sensing the discharge pressure of said pump; sensing the speed of said other roller member; correlating said pump discharge pressure with said speed of said other roller member to calculate the horsepower developed by said motorcycle at said speed. - View Dependent Claims (16, 17, 18)
