Embodiment 1

[0040] figure 1 It is a structural diagram of a lubricating oil temperature control system disclosed in the embodiment of the present application.

[0041] Such as figure 1 As shown, the lubricating oil temperature control system disclosed in this embodiment includes an oil temperature measurement device 14 , a processor 20 , and a heat exchange device 30 .

[0042] The oil temperature measuring device 14 is arranged on the gearbox 10 undergoing the endurance test, and is used for measuring the oil temperature of the lubricating oil and outputting the oil temperature value.

[0043] The oil temperature measuring device 14 is composed of a temperature sensor (not shown) and an analog-to-digital conversion circuit (not shown), and the temperature sensor is a thermal resistor or a thermocouple, which is arranged on the casing of the gearbox 10, because the casing of the gearbox is made of metal , is a good conductor of heat, so the temperature of the gearbox shell basically ref...

Embodiment 2

[0061] Figure 4 It is a structural diagram of a lubricating oil temperature control system disclosed in another embodiment of the present application.

[0062] Such as Figure 4 As shown, the lubricating oil temperature control system disclosed in this embodiment adds a heating device 40 on the basis of the previous embodiment.

[0063] The heating device 40 is connected to the processor 20, and the processor 20 is also used to compare the oil temperature value output by the oil temperature measuring device with the second preset oil temperature value, when the oil temperature value is lower than the second preset oil temperature value When the heating signal is output.

[0064] The heating device 40 includes a closed box, and a heater (not shown) is arranged in the box. The heating device is provided with two outlets communicating with the tank, which are respectively connected with the pump oil port 13 of the gearbox and the oil inlet 31 of the heat exchange device 30 th...

Embodiment 3

[0069] Figure 5 It is a structural diagram of a lubricating oil temperature control system disclosed in another embodiment of the present application.

[0070] Such as Figure 5 As shown, the outlet of the heating device 40 in this embodiment communicates with the pump oil port 13 and the observation oil port 12 of the gearbox respectively through pipelines, forming a parallel relationship with the heat exchange device 30 .

[0071] On the pipeline connecting the oil pump port 13 of the gearbox 10 and the oil inlet 31 of the heat exchange device 30, a normally closed first on-off valve T1 is arranged; A normally closed second on-off valve T2 is set on the road, and the processor 20 is also connected to the first on-off valve T1 and the second on-off valve T2 respectively.

[0072] When the processor 20 outputs the cooling signal, the first switch valve T1 is opened, and the lubricating oil can circulate through the heat exchange device 30, and the heat exchange device 30 si...

Abstract

The invention discloses a lubricating oil temperature control system which comprises an oil temperature measuring device, a dealer and a heat exchanging device. The oil temperature measuring device is arranged on a gear box and is used for measuring the oil temperature of lubricating oil and outputting an oil temperature value; the dealer is connected with the oil temperature measuring device and is used for outputting a cooling signal when the oil temperature value is larger than a first preset oil temperature value; an oil inlet and an oil outlet are formed in the heat exchanging device, the oil inlet and an oil pumping opening are communicated through a pipeline, and the oil outlet is communicated with an observing oil port through the pipeline; the heat exchanging device is connected with the dealer and is used for cooling the lubricating oil according to the cooling signal. According to the technical scheme, due to the fact that when the heat exchanging device is operated, the noise is low, judgment of abnormal sound of the gear box by an experimenter is not influenced and due to that fact that water does not need to be sprayed on a gear box shell body, corrosion of the gear box shell body and a test bed is avoided. Therefore, shortages of air blower cooling and water spraying cooling are effectively avoided.

Description

technical field [0001] The present application relates to the technical field of transmission detection, and more specifically, to a lubricating oil temperature control system. Background technique [0002] The gearbox is one of the most important assemblies in the field of automobile transmission. The service life of the gear pairs and shafts inside the gearbox directly affects the performance of the vehicle. Therefore, the gearbox needs to be tested for durability before it leaves the factory. During the durability test of the gearbox, the temperature of the gear lubricating oil has a direct impact on the service life of the gear pair. Therefore, the temperature of the lubricating oil must be strictly controlled during the durability test of the gearbox. [0003] At present, air-cooled or water-cooled methods are usually used to control the transmission oil temperature. The air-cooling method is to blow air directly to the gearbox through the blower to accelerate the heat...
