Abstract
The paper presents the results of modeling the developed braking torque of the brake based on the differentiation of brake pads by the moment of activation and the duration of interaction with the disc working surface. The relationship between the transverse movement of the brake pad and the developed braking torque of a drum-and-pad type power device, which is a two-mass oscillatory system (brake pad is a clamping element), is investigated.
Based on bench tests of drum-and-pad type braking devices with a different number of segment brake pads, an increase in power factors and stability indicators for power devices with six clamping elements relative to the serial brake design was proved: the coefficient of stabilization of the braking torque of a power device with six segment pads increased by 9.4 % relative to the serial brake device; the coefficient of vibration of the braking torque of the power device with six segment pads increased by 45.1 % relative to the serial braking device.
