Problems solved by technology
[0003] The disadvantages of the existing hydraulic transmission test device are: (1) The hydraulic system includes the oil supply system and the load system
Such two large oil circuits make the system structure complicated and increase the design and manufacturing cost
(2) The load devices in the existing fluid-viscous transmission test devices are generally mechanical (disc brakes or magnetic powder brakes), which have the disadvantages of complex structure, high manufacturing cost, and poor simulation conditions. The hydraulic systems of the loading device and the hydroviscous transmission test device are not related to each other, and the resources are not used efficiently

The invention discloses a liquid viscosity transmission tester with a hydraulic load device. The liquid viscosity transmission tester with the hydraulic load device comprises an oil supplying system and a simulation load loading system; an oil supplying system loop is connected with an oil supplying oil path coarse filter, a gear oil pump, an overflow valve, a speed regulating valve, a cooler, a liquid viscosity host, a flowmeter and an oil tank in sequence by a hydraulic pipeline. According to the simulation load loading system, a vane pump is adopted to replace the load device to load; the liquid viscosity host drives the load vane pump to work by the connection of a coupler; a simulation load loading system loop is connected with a load oil path coarse filter, the vane pump, a pilot operated compound relief valve and the oil tank in sequence by a hydraulic pipeline. The liquid viscosity transmission tester with the hydraulic load device is suitable for the test research of a liquid viscosity transmission technology, the system is greatly simplified while the basic demands of the test are met, so the system structure is deeply optimized and the design cost and the manufacturing cost are saved; the load loading system is closer to an actual working condition, so the system is more practical and reliable and has broad use value.
Description
technical field [0001] The invention relates to a fluid-viscous transmission test device, in particular to a fluid-viscosity transmission test device with a hydraulic loading device. technical background [0002] At present, the liquid-viscous speed-regulating clutch has a good energy-saving effect in high-power equipment such as fans, water pumps, and belt conveyors. extensive attention of experts and scholars. The development of hydroviscous clutch technology is inseparable from the hydroviscous transmission test device. Using the hydroviscous transmission test device to study the working characteristics of the oil film between the friction plates of the hydroviscous clutch can help us obtain the basic work of the hydroviscous clutch. data to provide a research basis for its industrialization. [0003] The disadvantages of the existing hydraulic-viscous transmission test device are: (1) The hydraulic system includes an oil supply system and a load system. Due to differe...
