An air inlet pipe connected with an air pump is arranged on the end surface of the function cylinder, and a control valve controlling pressure inside the function cylinder is arranged on the function cylinder. The pedal is driven to move through the function cylinder instead of manual stamping, so that labor intensity is decreased; meanwhile, the automobile brake pipe exhaust system is simple in structure, low in cost and widely applicable to the brake pipe exhaust field.
Description
Technical field
The utility model relates to a kind of brake pipe exhaust accessory, especially relates to a kind of brake line of automobile exhaust gear.
Background technology
Along with growth in the living standard, automobile has become a part indispensable in life, but when offering convenience to life, has also increased some puzzlements, as there is air in brake hydraulic line, causes brake portion to lose efficacy.For car load, carshop is evacuated brake hydraulic line conventionally, and then high pressure is filled into braking liquid in pipeline, drain all air, but in automobile use procedure, there is air in brake piping, after can not pipeline being evacuated, high pressure is filled pipeline again, what generally adopt is with artificial pedal brake pedal, constantly foot-operated, then pedal is stepped on to least significant end, turned on successively four bolts on brake cylinder, all spray a certain amount of braking liquid, this action repeats 3-4 time, the air in brake piping could be drained like this.And this mode is quite large to people's pin working strength, often step on once braking and all will step on to least significant end, before often turning on the bolt on brake cylinder, all will step on many times, in addition this action also needs repetition 3-4 time, very easily makes pin ache simultaneously.How to change the great repetitive operation of this intensity, easily complete the work of brake line of automobile air-discharging, brake line of automobile air-discharging device is just necessary.
As Chinese Patent Application No. 201220429478.2 discloses the electronic suction means of a kind of brake piping residual air, solve exhaust not thorough, waste time and energy, braking liquid corrosion operating personal and contaminated environment, cause the problems such as waste, it is characterized in that comprising motor, motor output shaft connecting screw rod formula axle, screw axle driven plunger, the external diameter of piston coordinates with the internal diameter of cylinder body, cylinder body is provided with air extractor vent towards one end of motor, sleeve is through the other end of cylinder body, screw axle is by sun and planet gear coupling bush, one end that sleeve is positioned at cylinder body is provided with drain oil, cylinder body is provided with the oil outlet that leads to liquid storage bottle on the cylinder chamber wall at drain oil place.But this cover system cost is relatively high.
Utility model content
The purpose of this utility model is to provide a kind of brake line of automobile exhaust gear with low cost, solves and manually gets rid of the problem that braking inner air tube is time-consuming, require great effort.
The utility model solves the technical scheme that its technical matters adopts: a kind of brake line of automobile exhaust gear, comprise acting cylinder, be arranged on the driven plunger in acting cylinder, driven plunger is fixedly connected with guide rod, the other end of guide rod is provided with the connection structure suitable with brake pedal, on guide rod, cover has recoil press spring, one end of recoil press spring to be pressed on acting cylinder inwall, and the other end is pressed in driven plunger; On the end face of acting cylinder, be also provided with the admission line being connected with air pump, be also provided with the control cock of control action in-cylinder pressure.
For making the stroke of guide rod and the stroke of brake pedal consistent, for fixation cylinder, be also provided with the bearing for acting cylinder is installed, described bearing comprises bearing adapter plate simultaneously, be arranged on the first column and the second column on bearing adapter plate, between acting cylinder and the first column, be provided with rotational pin; On the second column, be provided with the track groove suitable with brake-pedal travel, be provided with locating dowel pin on acting cylinder, locating dowel pin is placed in track groove.
Preferably, described control cock is arranged on acting cylinder.
For obtaining fast the air pressure in acting cylinder, ensure that brake-pedal travel puts in place, on described admission line, be also provided with air-pressure gauge.
The beneficial effects of the utility model: promote guide rod by driven plunger in acting cylinder and drive the rotation pedal travel being fixed together with guide rod, and make driven plunger return by the effect of control cock and pull back spring.Avoid manually repeating to trample brake pedal, the problem that labour intensity is large.Meanwhile, can ensure that each brake pedal is trampled puts in place.Described seat structure is simple, easy for installation, can meet the requirement of pedal arc stroke simultaneously.Whether the stroke that described air-pressure gauge can reflect brake pedal intuitively puts in place, is convenient to observe.
Below with reference to drawings and Examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment, as shown in Figure 1, a kind of brake line of automobile exhaust gear, comprises acting cylinder 1, is arranged on the driven plunger 2 in acting cylinder 1, and driven plunger 2 is fixedly connected with guide rod 3, and the other end of guide rod 3 is provided with the connection structure suitable with brake pedal.On guide rod 3, cover has recoil press spring 4, one end of recoil press spring 4 to be pressed on acting cylinder 1 inwall, and the other end is pressed in driven plunger 2.On the end face of acting cylinder 1, be also provided with the admission line 12 being connected with air pump, on described admission line 12, be also provided with air-pressure gauge 13.On acting cylinder 1, be provided with the control cock 5 of control action cylinder 1 internal pressure.
Fixing and making the stroke of guide rod 3 consistent with brake pedal for convenience of acting cylinder 1, also be provided with the bearing for acting cylinder 1 is installed, described bearing comprises bearing adapter plate 6, be arranged on the first column 7 and the second column 8 on bearing adapter plate 6, between acting cylinder 1 and the first column 7, be provided with rotational pin 9; On the second column 8, be provided with the track groove 10 suitable with brake-pedal travel, be provided with locating dowel pin 11 on acting cylinder 1, locating dowel pin 11 is placed in track groove 10.
The control cock of acting cylinder upper end is closed, export from air pump, by air-pressure gauge, air is pressed into acting cylinder upper end, along with the increase of terminal pressure on acting cylinder, acting cylinder guide rod moves downward together with spring, and brake pedal and acting cylinder guide rod link together, because brake pedal is to do circular motion, therefore acting cylinder rotate untie-sell rotate, simultaneously, locating dowel pin is moved in track groove, meet the requirement of brake pedal circular motion.In the time that brake pedal moves to bottom limit position, stop pressure air and the control cock of acting cylinder upper end is opened, under pull back spring effect, guide rod is got back to rapidly initial position, complete braking procedure 1 time, so repeat repeatedly braking procedure, in the time that brake pedal moves to bottommost, keep inflation pressure, also the bolt on four brake cylinders of automobile is turned on respectively simultaneously, all spray after a certain amount of braking liquid, and tighten respectively the bolt on brake cylinder, repeating like this 3-4 aforesaid operations process could drain brake piping air.
