Embodiment Construction
[0030] The embodiment of the present invention provides a dual-capacity hydraulic torque converter, which overcomes the problem of poor matching between the engine and the single-capacity hydraulic torque converter in practical applications. A detailed description will be given below in conjunction with the accompanying drawings.
[0031] Such as figure 2 As shown, a dual-capacity hydraulic torque converter in the embodiment of the present invention includes a cover wheel, a turbine 201, a guide wheel 202, a first pump wheel 204, and a second pump wheel 203. The cover wheel is connected to the engine through an input shaft. A pump wheel 204 is fixed on the cover wheel, a clutch 205 is provided between the second pump wheel 203 and the cover wheel, and the second pump wheel 203 is installed on the cover wheel through the clutch 205 . Therefore, in the torque converter, the engine drives the input shaft to rotate, and the cover wheel drives the first pump wheel 204 and the sec...

The invention discloses a dual-capacity hydraulic torque converter which is used for improving output of engine power and increasing operation efficiency of engineering machinery. The dual-capacity hydraulic torque converter comprises a first pump wheel (204), a second pump wheel (203) and a clutch (205), a working device (210), a first oil supply pump (211), a control valve (212), a second oil supply pump (208) and an oil cylinder (206), wherein the first oil pump (211) supplies oil to the working device (210) through an oil pipeline (214) and controls the opening and closing of the control valve (212) according to the pressure of the oil pipeline (214) so as to control oil supply to the oil cylinder (206) and further control the movement of the oil cylinder (206) and clutching of a clutch (205), thus the first pump wheel (204) is finally controlled to rotate freely, and the purposes of automatically selecting the capacity of the hydraulic torque converter by using the pressure of the working device and developing the efficacy of an engine furthest are achieved.
Description
technical field [0001] The invention relates to a hydraulic torque converter, in particular to a dual-capacity hydraulic torque converter. Background technique [0002] As one of the main components of the transmission system, the hydraulic torque converter has excellent characteristics such as automatic adaptability, continuously variable speed, good and stable low-speed performance, vibration reduction and vibration isolation, and no mechanical wear, and is irreplaceable by other transmission components. After a hundred years of development, the application of hydraulic torque converters has continued to expand, ranging from automobiles, engineering machinery, military vehicles to petroleum, chemical, mining, metallurgical machinery and other fields have been widely used. [0003] At present, domestic construction machinery (such as loaders) generally adopts a fully-adjusted engine, matches a hydraulic torque converter with a single capacity, and uses a quantitative workin...
