Abstract
The utility model discloses a life saving formula automotive spare braking device installed on the automotive rear axle in an automotive transportation system, and the utility model is mainly composed of a transistor lubricant pump, an operating cylinder, an oil return electromagnetic valve, an electronic circuit, etc. The life saving formula automotive spare braking device makes use of the electromagnet controlled by a transistor switch circuit to drive one plunger pump to press the oil into the two operating cylinders connected to the original brake adjustment arm to cause the automotive brake under the condition that the original automotive brake device is out of order. Thus, the traffic accident caused by brake failure can be efficiently avoided.
Description
The utility model discloses a kind of standby brake equipment of a kind of lifesaving formula automobile that is installed on the automobile axle, belong to automobile, transportation class.
For a long time, on large truck and passenger vehicle, its brake portion adopts the pneumatic brake device mostly, and this device braking effect is better, thereby is widely used.But when running into a certain position of brake portion and breaking down, damage as air compressor, the rubber diaphragm of gas piping gas leakage and compressed air brake cylinder breaks etc. and all to cause brake failure easily, and the generation traffic accident brings loss to the people's lives and property.Therefore a lot of scientific and technical personnel in home and abroad have carried out many explorations on this problem.As on some imported autos, installed a cover self-locking device additional.This device can make automobile when engine off, produces brake action automatically, with wheel lockup.But this also has some shortcomings, and is where bad as automobile, must repair in the original place, wants to tow back to factory and goes to drag motionless.In addition, China has produced a large amount of automobiles for these years, because structural restriction, this device is installed in inconvenience additional.Therefore the automobile brake problem remains on the present this level always.The traffic accident that causes because of brake failure happens occasionally.
The purpose of this utility model for existing automobile installs the standby brake equipment of a cover lifesaving formula automobile additional, so that automobile still can be braked effectively, is avoided the generation of accident just.With reference to the accompanying drawings its principle of work is explained in detail.
Accompanying drawing 1 is the structural representation of the standby brake equipment of lifesaving formula automobile;
Accompanying drawing 2 is electronic circuitries of this device.
From accompanying drawing 1, the standby brake equipment of this lifesaving formula automobile, it comprises by a transistor oil pump (5), operating cylinder (17), oil return solenoid valve (12), electronic circuit (25) etc. and forming.
The transistor oil pump of the standby brake equipment of this lifesaving formula automobile is made up of electromagnet (6), plunger pump (4), lever (16), oil sump (20), shell (22) etc.One end of lever (16) is fixed on the shell (22), and the same piston of the other end (2) connects, and the centre is connected with electromagnet (6).Plunger pump (4) is made up of the pump housing (1), piston (2), spring (3), inlet valve (15), delivery valve (13) etc.Plunger pump (4) is communicated with by the same oil sump of inlet valve (15) (20).Oil can be drawn into during work, can pass through again delivery valve (13) with oil pressure to operating cylinder (17).
Said operating cylinder (17) is made up of cylinder body (19), piston (18), and cylinder body (19) is installed on the automobile axle.One end of piston (18) is installed in the hole of cylinder body (19), and the other end connects with the braking adjusting arm on the former car (28).During work, piston (18) can be pushed into the other end by the oil that oil pump (4) comes from an end, can return an original end when not working again.
Said oil return solenoid valve (12) is made up of magnetic coil (9), valve body (11), valve rod (10).One end of valve rod (10) is placed on lower end in the hole of magnetic coil (9), and the other end is placed in valve body (11) hole.Oil return solenoid valve (12) is communicated with delivery valve (13) and oil sump (20) by oil pipe.
Said electronic circuit (25) is made up of devices such as transistor, resistance, electric capacity, relays.Electromagnet (6) is connected on B
1The position, magnetic coil (9) is connected on B
2The position, ten Ec are connected on anode, ground connection termination battery cathode.
Said oil sump (20) is made up of shell (22), dividing plate (24) and liquid oils.Liquid oils is contained in shell (22) bottom, and isolates with top by dividing plate (24).Oil sump (20) is by the same shell of fuel filler pipe (26) (22) external communications.
When automobile driver is found former brake system failure, the timely K switch in the close circuit, make in the circuit by transistor BG
1, BG
2The multi-vibrator starting of oscillation of forming is at BG
2Collecting electrode on produced a series of square wave, and pass through C
3Coupling adds to BG
3Base stage, make BG
3Conducting constantly one ends, and relay J adhesive constantly discharges.Normal battle of the J of relay J
1, also constantly magnet spool (8) to be connected one with ten EC and disconnect, soft iron (7) constantly sucked back is decontroled, and produces crank motion, and by lever (16), it is reciprocating to drive piston (2).During piston (2) upward movement, delivery valve (13) cuts out, and liquid oils is drawn into from inlet valve (15).When moving downward, inlet valve (15) check, oil extrudes from delivery valve (13), goes round and begins again like this, constantly with in the operating cylinder of the oil pressure to two in the oil sump, piston (18) is moved.Braking adjusting arm on the former car is progressively retracted, produce brake action.
After car stops fully, K switch is disconnected, circuit quits work, and plunger pump also quits work, and this is the braking procedure of this device.
Introduce the working process of return oil system below.
Oil return solenoid valve (12) normality is the oil circuit on-state, and promptly the same oil sump of delivery valve (13) (20) is communicated with.Behind the switch connection power supply, magnet coil (the 9) (B in the circuit diagram
2) must be electric, valve rod (10) is picked up, and fuel-return valve is closed, and can guarantee that like this oil that plunger pump extrudes enters operating cylinder (17).After closing K, magnet coil (9) dead electricity, valve rod (10) is rebounded by spring, delivery valve (13) is communicated with oil sump, pressure in the oil circuit disappears, and under the action of the spring in former car compressed air brake cylinder, piston (18) is retracted, oil in the operating cylinder is got back to oil sump (20), brake off state by oil return solenoid valve (12).
The effect of oil return pipe (14) is: when piston (18) moved to the top of oil cylinder (19), in time with oily bypass, protection oil cylinder (19) was not damaged, and plays the position limitation protection effect.
This spare braking device for lifesaving type automobile is only done to use in the situation of former automobile brake system failure, uses when not making conventional operation.
The enforcement of the standby brake equipment of lifesaving formula automobile has changed automobile hopeless situation of chaufeur under the situation of brake system failure, thereby has avoided the generation of this class accident effectively, for vehicle safety travel provides a kind of new guarantee.
