Návrh zkušebního stavu pro měření momentu tření kolových ložisek osobního automobilu

Abstract

The purpose of this study was to learn about an optimalal friction situation of the car so we could run different friction tests of the bearing settings and choose the same type, which has the lowest moment of friction as possible. we an then eliminate losses, which caused the car more consumption and worse emissions. the main part of the test is a friction wheel with the weight of almost half a tonne, which simulates the radial loads from the trolley. there is also, the original hub with double-row ball bearings, still frame, the test and speed sensors and two motors with the power 2.2 kW. It is therefore a profound Indirect Method. The methodology of measurement is precisely explained in Chapter 8.
