Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
For convenience of description, the words "upper", "lower", "left" and "right" in the present application, if any, merely indicate that the device or element referred to in the present application is constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention, since they are merely intended to be oriented in the upper, lower, left and right directions of the drawings themselves, and not to limit the structure, but merely to facilitate the description of the invention and to simplify the description. The description will be further described with reference to the drawings and specific examples.
Referring to FIG. 1, an example loader warm air assist system includes: the device comprises a first temperature control valve 1, a torque converter 2, a first evaporator 3, a transmission oil radiator 4, a gearbox 5, an air outlet 6 and an air supply device 7. Wherein:
the torque converter 2 is connected with an inlet of the first temperature control valve 1, an inlet of the first evaporator 3 is connected with a first outlet of the first temperature control valve 1, and an outlet of the first evaporator 2 is connected with an inlet of the transmission oil radiator 4. And a second outlet of the first temperature control valve 1 and an outlet of the transmission oil radiator 4 are connected with an inlet of the gearbox 5. The torque converter 2 is connected with an oil pump in the gearbox 5 to deliver high-temperature and high-pressure hydraulic oil into the torque converter 2.
When the temperature of the transmission oil in the torque converter 2 is lower than a preset temperature (such as 80 ℃), the transmission oil cannot enter the first evaporator 3 through the first temperature control valve 1, but enters the transmission oil radiator 4 through a bypass and then enters the gearbox 5 to continue circulating until the temperature reaches the preset temperature, and the function is beneficial to enabling the loader to quickly enter a working state in a low-temperature environment, shortening the hot vehicle time, saving energy and improving the working efficiency. Because if the temperature of the transmission oil in the torque converter 2 is lower than the preset temperature, the transmission oil is still allowed to release heat through the first evaporator 3, which leads to slower temperature rise of the transmission oil, the hot vehicle time is longer, and because the temperature of the transmission oil is reduced when the transmission oil passes through the first evaporator 3, and the part of heat is dissipated to the air through the first evaporator 3, which causes energy waste, through the control of the first temperature control valve 1, the heat dissipation through the radiator can be not allowed when the temperature of the transmission oil in the torque converter 2 does not reach the proper working temperature, but the circulation temperature rise is continued, thereby effectively overcoming the problems.
With continued reference to fig. 1, in another embodiment, the loader warm air auxiliary system further includes a second temperature control valve 8, a hydraulic component return line 9, a second evaporator 10, a hydraulic oil radiator 11, and a hydraulic oil tank 12. Wherein: the hydraulic component oil return pipeline 9 is connected with an inlet of a second temperature control valve 8, an inlet of a second evaporator 10 is connected with a first outlet of the second temperature control valve 8, and an outlet of the second evaporator 10 is connected with an inlet of a hydraulic oil radiator 11. And a second outlet of the second temperature control valve 8 and an outlet of the hydraulic oil radiator 11 are both connected with an inlet of a hydraulic oil tank 12. The hydraulic oil tank 12 is connected with an oil inlet of the hydraulic execution element, the hydraulic element oil return pipeline 9 is connected with an oil outlet of the hydraulic execution element, and hydraulic oil provides power for the hydraulic execution element. The second evaporator 10 is arranged in parallel with the first evaporator 3, thereby sharing the air supply device 7 and the air outlet 6.
Similarly, when the temperature of the hydraulic oil return in the hydraulic element return line 9 is low (for example, below 70 ℃), the hydraulic oil return cannot enter the second evaporator 10 through the second temperature control valve 8, but enters the hydraulic oil radiator 11 through the bypass and then enters the hydraulic oil tank 12 for continuous circulation until the temperature reaches a predetermined temperature, which also helps to enable the loader to quickly enter a working state in a low-temperature environment, helps to shorten the hot-car time, save energy, improve working efficiency, and overcome the problems that the heat cannot be effectively utilized, the hot-car time is long, and energy is wasted because the oil directly flows through the radiator after the vehicle is started in the conventional loader transmission oil and hydraulic oil radiating system.
Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
