In the working process, the variable speed pump is driven by the engine to run, and cooling lubricating oil is pumped from the oil tank through the filter. After transmission oil enters a gearbox overflow valve, one part of the transmission oil flows out of a gearbox clutch system for use, the other part of the transmission oil acts on a valve core of the gearbox overflow valve to move, and then enters an oil inlet hole formed in a guide wheel seat along a pipeline inside a torque converter shell, so that the transmission oil enters a pump wheel, a guide wheel and a turbine. The torque converter and the gearbox of loader require to possess higher heat-sinking capability when the summer work, therefore torque converter and gearbox pass through the oil circuit and directly link to each other with the radiator, and transmission oil is whole to participate in the heat dissipation, and this kind of connected mode has caused the loader to work under chilly operating mode, and transmission oil participates in the heat dissipation in real time, causes the oil temperature to hang down excessively, and whole car work efficiency reduces, and has increased the oil consumption.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
Disclosure of Invention
The invention provides the energy-saving device for the transmission system of the loader, aiming at avoiding the defects in the prior art, and the energy-saving device effectively solves the problem that the transmission system of the existing loader is low in efficiency in a low-temperature environment.
The technical scheme adopted by the invention is as follows:
the temperature controller comprises a temperature control valve, a temperature sensor and a control circuit, a first control setting value and a second control setting value are arranged in the temperature controller, the first control setting value is larger than the second control setting value, the temperature control valve comprises an oil inlet, a first oil outlet and a second oil outlet, the oil outlet of the torque converter is connected with the oil inlet of the temperature control valve through a transmission oil path, the first oil outlet of the temperature control valve is connected with the oil inlet of the gearbox through a transmission oil path, the second oil outlet of the temperature control valve is connected with the oil inlet of the radiator through a transmission oil path, and the oil outlet of the radiator is connected with the oil inlet of the gearbox through a transmission oil path.
The first control set value is 95-105 ℃, and the second control set value is 85-90 ℃.
When the ambient temperature detected by the temperature sensor is not lower than a first control set value, the control circuit controls the first oil outlet to be closed and the second oil outlet to be opened, and the flow path of the transmission oil sequentially comprises a torque converter, a temperature control valve, a radiator and a gearbox.
When the ambient temperature detected by the temperature sensor is not higher than a second control set value, the control circuit controls the first oil outlet to be opened and the second oil outlet to be closed, and the flow path of the transmission oil sequentially comprises a torque converter, a temperature control valve and a gearbox.
When the ambient temperature sensed by the temperature sensor does not reach the first control setting or the second control setting, the transmission oil maintains the previous flow path.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
when the ambient temperature is higher and reaches a first control set value, the transmission oil flows out of the second oil outlet of the temperature control valve and enters the radiator, and then enters the gearbox after heat dissipation is finished, so that the oil temperature in the gearbox is ensured to be within a proper temperature range. When the ambient temperature is lower than a second control set value, the transmission oil flows out of the first oil outlet and directly flows back to the gearbox, the transmission oil is not subjected to heat dissipation and only circulates in the transmission oil, and the oil temperature of the transmission oil is ensured to be always at a proper temperature. The invention effectively solves the problem of low efficiency of the transmission system of the loader in a low-temperature environment, can save more than 3% of oil consumption, and has the advantages of simple structure, high reliability and lower manufacturing cost.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, but the present invention is not limited to these examples.
As shown in fig. 1, an energy-saving device for a loader transmission system comprises a torque converter 1, a temperature controller, a radiator 2 and a gearbox 3 which are connected through a transmission oil path. The temperature controller comprises a temperature control valve 4, a temperature sensor and a control circuit, and a first control set value and a second control set value are arranged in the temperature controller. The first control set value is 95 ℃, 100 ℃, 105 ℃ or any value between 95 ℃ and 105 ℃. The second control setpoint is 85 ℃, 87 ℃, 90 ℃ or any value between 85 ℃ and 90 ℃.
The temperature control valve 4 comprises an oil inlet 41, a first oil outlet 42 and a second oil outlet 43, the oil outlet of the torque converter 1 is connected with the oil inlet 41 of the temperature control valve 4 through a transmission oil path, the first oil outlet 42 of the temperature control valve 4 is connected with the oil inlet of the transmission case 3 through a transmission oil path, the second oil outlet 43 of the temperature control valve 4 is connected with the oil inlet of the radiator 2 through a transmission oil path, and the oil outlet of the radiator 2 is connected with the oil inlet of the transmission case 3 through a transmission oil path.
When the ambient temperature detected by the temperature sensor is not lower than a first control set value, the control circuit controls the first oil outlet 42 to be closed and the second oil outlet 43 to be opened, and the flow path of the transmission oil sequentially comprises the torque converter 1, the temperature control valve 4, the radiator 2 and the gearbox 3, namely the transmission oil is required to firstly dissipate heat through the radiator 2 and then flow back to the gearbox 3 after coming out of the torque converter 1, so as to ensure that the oil temperature in the gearbox 3 is within a proper temperature range.
When the ambient temperature detected by the temperature sensor is not higher than a second control set value, the control circuit controls the first oil outlet 42 to be opened and the second oil outlet 43 to be closed, and the flow path of the transmission oil sequentially comprises the torque converter 1, the temperature control valve 4 and the gearbox 3, namely the transmission oil directly flows back to the gearbox 3 without being radiated by the radiator 2, so that the transmission oil is always at a proper temperature, and the problem of low working efficiency of the loader under the working condition of low temperature is effectively solved.
When the ambient temperature sensed by the temperature sensor does not reach the first control setting or the second control setting, the transmission oil maintains the previous flow path. Specifically speaking: when the ambient temperature detected by the temperature sensor reaches the second control set value and then is heated from the second control set value to the first control set value but does not reach the first control set value, the flow path of the transmission oil still maintains the flow path of the transmission oil when the ambient temperature is not higher than the second control set value, namely the flow path of the transmission oil sequentially comprises a torque converter 1, a temperature control valve 4 and a gearbox 3; when the ambient temperature detected by the temperature sensor reaches the first control set value, the temperature is reduced from the first control set value to the second control set value, but the ambient temperature does not reach the second control set value, the flow path of the transmission oil still maintains the flow path of the transmission oil when the ambient temperature is higher than the first control set value, namely the flow path of the transmission oil sequentially comprises the torque converter 1, the temperature control valve 4, the radiator 2 and the gearbox 3.
