Abstract
The invention provides a compression device of an air booster. The compensation device of the air booster aims to ensure that the force acting on a clutch by a push rod of the air booster is kept within a work range when the hydraulic oil pressure of the air booster is insufficient. According to the compensation device of the air booster, a travel switch is additionally arranged on a pedal of the clutch, the travel switch is connected with a power source, a pressure switch and a warning light through wires, and the pressure switch is additionally arranged on an oil inlet pipe of the air booster. An electromagnet and a compensation push rod are mounted on the outer side of the wall of a working oil cavity of the air booster, the front end of the compensation push rod extends into the working oil cavity of the air booster and is placed on one side of a piston, and the electromagnet is connected with the power source and the warning light through wires. The compensation device of the air booster is simple in structure, convenient to mount, and capable of guaranteeing the normal work of the air booster and giving out an alarm when an oil leakage situation happens.
Description
Technical field
The invention belongs to auto parts machinery field.
Background technique
On medium-heavy automobile, as the vitals of clutch operation, the separation that clutch air booster is clutch provides power, makes clutch pedal spry and light sensitive, reduces the labor intensity of driver.The fine or not direct relation of clutch air booster performance the task performance of clutch and the Security of running.
If hydraulic oil leaked before entering booster working oil chamber, then whole booster very easily lost efficacy, and affected the Security of running.
Summary of the invention
The object of the invention is to ensure when booster hydraulic oil pressure is not enough booster push rod effect trying hard to keep on the clutch be held in operating range within air booster compensation device.
Position limit switch of the present invention is installed at clutch pedal place, and position limit switch is connected with power supply, pressure switch, beacon by wire, and pressure switch is installed at booster oil inlet pipe place; Electromagnet is arranged on outside booster working oil chamber wall with compensation push rod, compensates push rod front end and stretches into booster working oil chamber and be placed in piston side, and electromagnet is by wire and power supply, and beacon is connected.
Structure of the present invention is simple, is convenient to install, and when there is leakage of oil situation, ensureing the normal work of booster and giving the alarm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Position limit switch 4 of the present invention is installed at clutch pedal place, and position limit switch 4 is connected with power supply 5, pressure switch 2, beacon 15 by wire, and pressure switch 2 is installed at booster oil inlet pipe place; Electromagnet 10 is arranged on outside booster working oil chamber wall with compensation push rod 11, compensates push rod 11 front end and stretches into booster working oil chamber and be placed in piston 12 side, and electromagnet 10 is by wire and power supply 5, and beacon 15 is connected.
Below in conjunction with accompanying drawing, the present invention is described in detail:
Clutch booster compensation device of the present invention primarily of pressure relay, position limit switch, electromagnet, the compositions such as push rod.
When car load works, when driver's pin stepping on clutch pedal, hydraulic oil enters booster working oil chamber 6, a part acts on hydraulic piston 3, promote booster push rod 1, another part promotes piston 12, and piston promotes core bar, open poppet valve 14, make pressurized air enter atmospheric pressure cavity 9, air pressure promotes push rod 7, and the hydraulic coupling acting in conjunction of another part oil pocket is on hydraulic piston 3, hydraulic piston promotes booster push rod 1, and controlled clutch is separated.Design compensation device, occurs still can ensureing that booster normally works and warns to driver when leaking at hydraulic oil.
Often drive position limit switch 4 and be installed at clutch pedal place, when driver's foot pedal, switch closes.Position limit switch is by wire and power supply 5, and pressure switch 2 is connected.
Often open pressure switch 2 and be installed at booster oil inlet pipe place, when the hydraulic oil in oil inlet pipe occurs to leak, hydraulic oil pressure declines, and now pressure switch closes.Pressure switch is by wire and position limit switch 2, and beacon 15 is connected.
Electromagnet 10 is arranged on just to piston place outside booster working oil chamber wall with compensation push rod 11, and electromagnet 10 is by wire and power supply 5, and beacon 15 is connected.
Beacon 15 is arranged on operator cabin, and by wire and electromagnet 10, pressure switch 2 is connected.
At driver's foot pedal and hydraulic oil occur leak time whole circuit communication, electromagnet 10 works and promotes to compensate push rod 11, and then open poppet valve 14, pressurized air is made to enter atmospheric pressure cavity 9, now atmospheric pressure passes through power piston 8, push rod 7 and hydraulic coupling acting in conjunction on booster push rod 1, controlled clutch is separated, and ensures the normal work of booster.
When circuit communication, the beacon 15 of operator cabin lights, and informs that driver's hydraulic oil leaks.
