Description
Technical field
The present invention relates to the detection device of a kind of automobile, especially relate to a kind of detection device of clutch master cylinder idle stroke with accessory.
Background technique
Clutch master cylinder is connected in the automobile clutch control system, and the pressure oil that it produces passes through line transportation in the filler opening of clutch booster.The idle stroke of clutch master cylinder just is meant when clutch master cylinder is set up the pressure of 0.1MPa, the displacement that piston moves.If idle stroke is too small, on the clutch master cylinder filler opening is blocked soon so, can't build pressure smoothly, if idle stroke is excessive, to build pressure will be very slow to clutch master cylinder so, pedal travel will strengthen, and will feel under the weather during driver's operation.
The method of the detection idle stroke of existing technology generally all is to adopt special-purpose monitor station to test, and it can measure the concrete numerical value of idle stroke accurately.This detection facility cost is high, cost an arm and a leg, and it is long to detect time of cost, moves inconvenience.Therefore be necessary design and invent simple and effective easy-operating device, come to judge fast whether the clutch master cylinder idle stroke is overproof.
Summary of the invention
The present invention seeks to overcome above-mentioned deficiency, provide a kind of simple and reasonable, easy to detect, the detection device of the clutch master cylinder idle stroke that cost is low.
The technological scheme that technical problem adopted that the present invention solves is: a kind of detection device of clutch master cylinder idle stroke, it is characterized in that comprising limit stoper and inflator, and corresponding about limit stoper and inflator; Limit stoper comprises spacing cylinder; Spacing cylinder output terminal be provided with externally threaded push rod head scyewed joint, can adjust the overhang of push rod, be installed with limiting stopper on the push rod; Push rod passes side plate, and limiting stopper can be regulated on push rod in turn; Inflator comprises the inflation cylinder, and the output terminal of inflation cylinder and the head of pneumatic head join.
During use, be placed on clutch master cylinder between push rod and the push rod, the push rod head is just contacted with the piston of clutch master cylinder; And through regulating the overhang of push rod with respect to spacing cylinder, the side of adjustment clutch master cylinder is takeed on the test gap between plane and the side plate, and this test gap is for measuring the lower limit of different clutch master cylinder idle strokes; Open inflator then; Pneumatic head withstands on oil outlet one end of clutch master cylinder, and clutch master cylinder is advanced left and clamps, and this moment is because push rod is motionless; Clutch master cylinder is moved to the left the test gap of setting, the test gap that piston has then advanced relatively and to have set.External then source of the gas is ventilated to clutch master cylinder to the liquid port of clutch master cylinder through pneumatic head, and whether the filler opening that observe the clutch master cylinder of having ventilated this moment has gas leak phenomenon, so just can judge fast that the idle stroke lower limit is overproof; Then through regulating the limiting stopper on the push rod; Make it and side plate between certain test gap arranged; This measures the gap for measuring the upper limit of different clutch master cylinder idle strokes, opens spacing cylinder again, and push rod is advanced to the right; Thereby the piston that promotes clutch master cylinder moves to right, and the limiting stopper that the distance that moves is set before being exactly and that test gap between the side plate.Whether the filler opening that observe the clutch master cylinder of having ventilated this moment has gas leak phenomenon, so just can judge fast that the idle stroke upper limit is overproof.What will explain here a bit is exactly: when find gas leakage in the lower position, idle stroke then is described greater than this lower limit, lower limit is qualified; When do not find gas leakage at upper limit position, idle stroke then is described less than this CLV ceiling limit value, the upper limit is qualified, and this clutch master cylinder idle stroke is qualified, and is not overproof.Otherwise then idle stroke is overproof, and this clutch master cylinder is defective.
As preferably, the present invention also is provided with finder, because the filler opening of general clutch master cylinder is all bigger, is not easy to observe little leakage phenomenon.Above-mentioned limit stoper and the top between inflator are provided with finder, and finder comprises and hold out against cylinder, and the output terminal and the plug head that hold out against cylinder join, and plug is provided with the observation aperture, observes aperture and communicates with the clutch master cylinder filler opening.Accomplish limit stoper and inflator to the clutch master cylinder clamping after; Open and hold out against cylinder; Hold out against the plug on the push rod on the filler opening of clutch master cylinder,, coat leak test agent such as soap solution because of plug is provided with the observation aperture; When pneumatic head during, can be intuitively whether overproof according to observing whether the leak gas idle stroke of judging this clutch master cylinder of aperture to the inflation of the liquid port of clutch master cylinder.
The end face and the side sheet room of spacing cylinder are installed with stud bolt, and stud bolt is rotary with nut and is fastened on the end face of spacing cylinder and the left and right side of side plate respectively; Front at the inflation cylinder is provided with fixed plate, and pneumatic head passes the middle part of fixed plate, is installed with stud bolt between the end face of inflation cylinder and fixed plate, and stud bolt is rotary with nut and is fastened on the end face of inflation cylinder and the left and right side of fixed plate respectively.Usually between spacing cylinder and inflation cylinder, be fixedly connected on left and right side with a fixture.
The invention has the beneficial effects as follows: the present invention waits through spacing cylinder, side plate, limiting stopper and controls the test gap; Measure different clutch master cylinder idle strokes; Whether the idle stroke that can judge this clutch master cylinder fast overproof, and have simple in structure, conveniently moving; With low cost, detect effectively and the advantage of simple operation.
