Abstract
The utility model relates to a centralization-lubrication parking machine circuit, and belongs to the technical field of automobile parking machine circuits. The centralization-lubrication parking machine circuit may be used for shutting down a centralization lubrication system at a parking state, and controls a centralization lubrication relay through on and off of a parking braking switch, thereby realizing control of the working state of the centralization lubrication relay, adding a function of shutting down when a vehicle is parked or stands on the site while maintaining the original centralization lubrication function of the vehicle, and preventing phenomena of excessive lubrication and lubricating oil overflow of the lubricating system at a whole vehicle parking state.
Description
Technical field
The utility model relates to the parked dynamo-electric road technique of automobile field, is specifically related to a kind of central oiling and stays halt circuit.
Background technology
As shown in Figure 1, existing automatically controlled centralized grease lubricating system pull up circuit is comprised of source switch 1, central oiling controller 3, storage battery 2 and interlock circuit.In Vehicle Driving Cycle process, centralized grease lubricating system is realized the function of timed lubrication in vehicle use procedure by central oiling controller.The working power of central oiling controller is directly provided by storage battery, and parking is shut down and need to be realized by cutting off the electricity supply.
In conjunction with Fig. 1, can find out; because central oiling controller can only could be realized parked machine by cutting off the electricity supply, so which requires chaufeur must close the mode of operation that battery feed main supply switch could stop centralized grease lubricating system after vehicle parking engine off.When vehicle is during in mode of operation that parking and source switch do not disconnect, centralized grease lubricating system still works on, and can cause vehicle excessively lubricated and excessive.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is: how to design a kind of central oiling and stay halt circuit, solve over-lubrication and the excessive problem of lubricating oil under current centralized grease lubricating system car load suspended state.
(2) technical scheme
In order to solve the problems of the technologies described above; the utility model provides a kind of central oiling to stay halt circuit; comprise braking during standstill switch, central oiling relay, central oiling controller; the first pin of the coil of described central oiling relay is connected with one end of braking during standstill switch; the second pin is connected with one end of central oiling controller; the 3rd pin respectively with the other end of braking during standstill switch, and the other end of central oiling controller connects.
Preferably, the other end of described the 3rd pin and braking during standstill switch, and be connected with source switch between the other end of central oiling controller.
Preferably, the other end of described the 3rd pin and braking during standstill switch, and between the other end of central oiling controller, be also connected with battery pack.
(3) beneficial effect
The utility model is the circuit that under a kind of parking state, centralized grease lubricating system is shut down; this circuit is controlled central oiling relay by the break-make of braking during standstill switch; thereby realize the control to central oiling controller mode of operation; thereby the stopping function while increasing vehicle parking or original place standby under the prerequisite that retains former vehicle centralized lubricating function, and then control lubricating system over-lubrication and the excessive phenomenon of lubricating oil under car load suspended state.
Accompanying drawing explanation
Fig. 1 is existing automatically controlled centralized grease lubricating system working circuit diagram;
Fig. 2 is circuit diagram of the present utility model.
The specific embodiment
For making the purpose of this utility model, content and advantage clearer, below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 2, the utility model provides a kind of central oiling to stay halt circuit, comprise braking during standstill switch 4 (being parking brake), central oiling relay 5 (is general relay, comprise coil), central oiling controller 6 (for realize parked machine by cutting off the electricity supply), the first pin 85 of the coil of described central oiling relay 5 is connected with one end of braking during standstill switch 4, the second pin 87a is connected with one end of central oiling controller 6, the 3rd pin 86 respectively with the other end of braking during standstill switch 4, and the other end of central oiling controller 6 connects, the 3rd pin 86 is also connected with four-limbed 30 simultaneously.The other end of described the 3rd pin 86 and braking during standstill switch 4, and between the other end of central oiling controller 3, be connected with source switch 7,12V battery pack 8.Central oiling controller 6 can be used existing chip microcontroller.
The principle of work that this central oiling is stayed halt circuit is the state of central oiling relay 5 judgement vehicle parking switches 4; by controlling the coil cut off of central oiling relay 5; and then make the 6 power-off work of central oiling controller; central oiling quits work, thereby realizes the object that under parking or original place readiness for action, central oiling is shut down.In conjunction with Fig. 2, the as follows of specific works principle described:
1) closed electrical source switch 7, when vehicle parking (mode of operation that source switch does not disconnect), braking during standstill switch 4 opened to (being pull-up parking brake).Now, the first pin 85 and the ground of the coil of central oiling relay 5 are connected, and the 3rd pin 86 and the first pin 85 form path.Coil motion by the contact of central oiling relay 5 by the second pin 87a magnetic to the five pins 87; and then four-limbed 30 and the second pin 87a are disconnected, now, centralized grease lubricating system power supply is cut off; central oiling is shut down, the generation of oil leakage phenomenon while avoiding original place standby.
2), when vehicle launch, braking during standstill switch 4 is disconnected to (unclamping parking brake).Now, the first pin 85 and the ground of the coil of central oiling relay 5 disconnect, and the 3rd pin 86 and the first pin 85 form and open circuit.Coil unclamps, and the four-limbed 30 of central oiling relay 5 and the second pin 87a connect; Now, the power connection of central oiling controller 6, the centralized grease lubricating system state of resuming work.
As can be seen from the above embodiments; the utility model is controlled central oiling relay by the break-make of braking during standstill switch; thereby realize the control to central oiling controller mode of operation; thereby the stopping function while increasing vehicle parking or original place standby under the prerequisite that retains former vehicle centralized lubricating function, and then control lubricating system over-lubrication and the excessive phenomenon of lubricating oil under car load suspended state.Adopt of the present utility model staying after halt circuit; chaufeur only need to be opened the stopping function that braking during standstill switch (being pull-up parking brake) just can be realized vehicle centralized grease lubricating system when parking (power supply does not disconnect), more rationally, science, reliable.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
