Brake pedal pressure signal sending unit
Abstract
Abstract A HYDRAULIC PRESSURE SIGNAL SENDING UNIT FOR USE WITH AN ASSEMBLY FOR MEASURING THE FORCE APPLIED TO AN AUTOMOBILE BRAKE PEDAL BY THE FOOT OF AN OPERATOR, THE SENDING UNIT BEING DETACHABLY MOUNTABLE UPON A CONVENTIONAL BRAKE PEDAL AND BEING CONNECTED WITH A REMOTE FLUID PRESSURE GAUGE. THE SENDING UNIT IS OPERATED MANUALLY AND IS DESIGNED TO TRANSLATE FOOT PRESSURE INTO HYDRAULIC PRESSURE WHICH IS TRANSMITTED THROUGH A FLEXIBLE HOSE TO THE PRESSURE GAUGE. THE SENDING UNIT INCLUDES A ROLLING DIAPHRAGM MOUNTED IN A HOUSING, AND TO WHICH DIAPHRAGM FOOT PRESSURE IS APPLIED THROUGH A PIVOTED PRESSURE PLATE MOUNTED ON SAID HOUSING AND A TREADLE PIVOTALLY MOUNTED ON SAID PRESSURE PLATE. THE PIVOTAL AXIS OF THE PRESSURE PLATE IS ADJACENT ONE END THEREOF AND PARALLEL WITH THE PIVOTAL AXIS OF THE READLE, WHICH IS ABOUT MIDWAY OF THE LENGTH OF THE PRESSURE PLATE. THIS ARRANGEMENT, COUPLED WITH THE ROLLING DIAPHRAGM MAKES THE SENDING UNIT INSENSITIVE TO THE ANGLE AT WHICH FOOT PRESSURE IS APPLIED.
