METHOD OF APPROXIMATE DETERMINATION OF AVERAGE TEMPERATURE OF BRAKING DEVICE STRUCTURAL MEMBER AND DEVICE INTENDED FOR ITS REALIZATION Russian patent published in 1998 - IPC

FIELD: check of car braking devices. SUBSTANCE: thermal deformation h_sth of structural member (for example of brake drum) is determined by values of measured formation h_s and elastic deformation h_sel calculated with due regard for structural member material dependent from temperature of modulus of elasticity E. Average temperature sought for is determined by value h_sth from dependence of deformation from temperature obtained preliminarily under conditions of brake pressure absence. Device intended for realization of given method has structural member deformation sensor which can be made as sensor of angle of turn of brake drum cam and pressure sensor in brake system. Sensors are connected to microprocessor computing unit. EFFECT: more efficient checking. 7 cl, 1 dwg
