Abstract
The invention discloses an automatic preheating system for lubricating oil of a transmission. The automatic preheating system for the lubricating oil of the transmission comprises a gearbox case, wherein an electric heater is arranged in a lubricating oil sump inside the gearbox case; an oil temperature sensor is mounted at the bottom of the gearbox case; a signal output end of the oil temperature sensor is connected with a control end of a temperature control switch; one end of the electric heater is connected with a positive electrode of a power supply through the temperature control switch, and the other end of the electric heater is connected with a negative electrode of the power supply. The automatic preheating system for the lubricating oil of the transmission monitors the oil temperature through the oil temperature sensor; when the oil temperature is lower than a certain set value, the temperature control switch is switched on; the electric heater located in the lubricating oil sump is electrified to work; the temperature of the lubricating oil rapidly rises. After the oil temperature rises to a designated value, and when the viscosity of the lubricating oil reaches a normal range, the temperature control switch is switched off; the electric heater stops heating. The automatic preheating system for the lubricating oil of the transmission can be used as a selective pairing device of the transmission, and is used for automatically preheating the lubricating oil of the transmission when a vehicle is started.
Description
[technical field]
The invention belongs to pre-heating system field, relate to a kind of transmission oil automatic preheating system.
[background technology]
The normal work of variator be unable to do without lubricating oil, when severe cold area or winter driving, the temperature that vehicle is initial
Spending extremely low, the lubricating oil very thickness in variator is possibly even in curdled appearance.If variator is not carried out
Preheating, makes the temperature of lubricating oil raise, and viscosity reaches the lubrication of normal condition, internal gear and other parts
Can be by considerable influence.Meanwhile, lock unit conversion overlong time, synchronous effect is poor, directly influences driving experience.
Finding according to market survey, at present in severe cold area or winter, user less pays close attention to preheating or the employing of variator
The preheating method (as used thermal-flame direct baking) of mistake, is all unfavorable for the normal use of variator.
There is no a variator that can realize lubricating oil self-heating on the market at present.
[summary of the invention]
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of transmission oil is the most pre-
Hot systems.
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions:
A kind of transmission oil automatic preheating system, including gear box casing, the lubrication within gear box casing
Arranging electric heater in oil sump, the bottom of gear box casing is provided with oil temperature sensor, the signal of oil temperature sensor
Outfan is connected with the control end of temperature detect switch (TDS)；Temperature detect switch (TDS) and positive source phase are passed through in one end of electric heater
Even, the other end is connected with power cathode.
The present invention is further improved by:
Described power supply uses car load power supply or external power.
Described electric heater uses electrical heating wire, is installed in the mounting bracket in transmission housing body, and electrical heating
Silk penetrates, passes the part of gear box casing, is connected with gear box casing sealed insulation.
Be provided with between described electric heater and gear box casing for reduce electric heater and gear box casing it
Between resonance buffer unit.
It is provided with low voltage warning lamp on described temperature detect switch (TDS), electric heater can not be driven at input supply voltage
Alarm.
Described oil temperature sensor is seal-installed on case of transmission.
Compared with prior art, the method have the advantages that
Transmission oil low-temperature preheating system of the present invention, mainly by oil temperature sensor, temperature detect switch (TDS), electrical heating
Device forms, and monitors oil temperature by oil temperature sensor, and after oil temperature is less than certain setting value, temperature detect switch (TDS) closes,
The electric heater energising work being positioned in lubricating oil bath, lubricating oil is brought rapidly up.After oil temperature rises to designated value,
When lubricating oil viscosity reaches normal range, temperature detect switch (TDS) disconnects, and electric heater stops heating.The present invention can make
For the matching device of variator, automatically transmission oil is preheated when vehicle launch, improve change
Speed device, for the adaptability of ambient temperature, improves Consumer's Experience.
[accompanying drawing explanation]
Fig. 1 is the overall structure schematic diagram of the present invention.
Wherein: 1-power supply；2-temperature detect switch (TDS)；3-oil temperature sensor；4-electric heater；5-lubricating oil bath；6-
Gear box casing.
[detailed description of the invention]
Below in conjunction with the accompanying drawings the present invention is described in further detail:
Seeing Fig. 1, the present invention includes gear box casing 6, sets in the lubricating oil bath 5 within gear box casing 6
Putting electric heater 4, the bottom of gear box casing 6 is provided with oil temperature sensor 3, no matter the gradient residing for vehicle
Oil temperature can be monitored.The signal output part of oil temperature sensor 3 is connected with the control end of temperature detect switch (TDS) 2；Electrical heating
One end of device 4 is connected with power supply 1 positive pole by temperature detect switch (TDS) 2, and the other end is connected with power supply 1 negative pole.Power supply
1 uses car load power supply or external power.Electric heater 4 uses electrical heating wire, is installed in gear box casing 6
Mounting bracket on, and electrical heating wire penetrates, passes the part of gear box casing 6, close with gear box casing 6
Envelope insulation connects.It is provided with between electric heater 4 and gear box casing 6 for reducing electric heater 4 and speed change
The buffer unit of resonance between tank shell 6；Low voltage warning lamp it is provided with, at input power on temperature detect switch (TDS) 2
Voltage can not drive electric heater alarm.Oil temperature sensor 3 is seal-installed on case of transmission 6.
As it can be seen, oil temperature sensor 3 sends oil temperature signal to temperature detect switch (TDS) 2, after oil temperature is less than setting value,
Temperature detect switch (TDS) 2 closes, and electric heater 4 is energized work, and lubricating oil is brought rapidly up.When oil temperature rises to setting value
After, lubricating oil viscosity reaches normal range, and temperature detect switch (TDS) 2 disconnects, and electric heater 4 stops heating.
Above content is only the technological thought that the present invention is described, it is impossible to limit protection scope of the present invention with this, all
It is the technological thought proposed according to the present invention, any change done on the basis of technical scheme, each fall within this
Within the protection domain of bright claims.
