2.SYMBOLS AND DEFINITIONS (The reference brake symbols shall have the
suffix e) P=normal reaction of road surface on the axle under static conditio
ns C=camshaft input torque Cmax=maximum technically permissible camshaft input torque C0=threshold camshaft input torque, i.e. minimum camshaft torque necessary to produce a measurable brake torque R=tyre rolling radius (dynamic) T=brake force at tyre/road interface M=brake torque = T 7 R z=braking rate P T = RPM s=actuator stroke (working stroke plus free stroke) Sp=effective stroke - the
...[+++]stroke at which the output thrust is 90 % of the average thrust (ThA) ThA=average thrust - the average thrust is determined by integrating the values between one-third and two-thirds of the total stroke (smax) >START OF GRAPHIC>
