Description
Technical field
The utility model belongs to wheeled vehicle, agricultural equipment and engineer machinery test apparatus field, relates to a kind of hydrodynamic unit and mechanical transmission component blocking test platform.
Background technology
At present, at home and abroad Chang Yong wheeled vehicle, agricultural equipment and engineer machinery test apparatus field comprise the drive disk assembly testing table of automobile, tractor, engineering machinery etc., mostly by engine, formed by test specimen, torque speed sensor and loader.Transmission test bench structure kind is more, and transmission test bench commonly used roughly is summarised as open type testing table and blocking test platform: the test power of open type testing table all consumes, and the test power of blocking test platform is most of to be recycled.Though the open type testing table is easy to configuration, because of its test power all is converted into heat energy, must be equipped with cooling device, cost is higher, especially carries out high-power transmission test, more should not adopt the open type testing table.Electric blocking test platform in the blocking test platform adopts the AC and DC generator for electricity generation to load, and electricity can feed back to motor, or directly imports electrical network, and the electric energy major part can reclaim.This testing table is applied widely, but the AC and DC power of the assembling unit is more than or equal to by test specimen power.In addition, the regulator control system investment is also bigger.If when test was of little use, the electrical equipment regulator control system was out of order easily.And hydrodynamic unit and mechanical transmission component blocking test platform have been obtained good effect in product testing.
The utility model content
The purpose of this utility model is to provide a kind of functional reliability good, simple in structure, and cost is lower, energy savings, but the hydrodynamic unit of a tractor serves several purposes and mechanical transmission component blocking test platform.
The technical solution of the utility model is: hydrodynamic unit and mechanical transmission component blocking test platform comprise engine, gear case, torque speed sensor, by test specimen, gear governing box, Cardan shaft, loader; Engine is connected with gear case by ring flange, gear case is connected with torque speed sensor by ring flange, torque speed sensor by ring flange be connected by test specimen, be connected by the input shaft of ring flange by test specimen with the gear governing box, the output shaft of gear governing box is connected with loader by Cardan shaft, loader is connected with gear case by ring flange, forms a closed system.
Loader is a slip clutch, and slip clutch is the secondary composition of multiple-piece wet friction.
Can be fluid-flywheel clutch and gearing thereof by test specimen; Also can be fluid torque-converter and wheel box thereof by test specimen.
The utility model adopts the good effect that produces after the technique scheme to be: functional reliability is good, and is simple in structure, and cost is lower, saves the energy more than 60～80%, so testing table engine power only is by about 20% of test specimen power.But a tractor serves several purposes both can have been done hydrodynamic unit (coupling device and torque converter) test simultaneously, also can do the test of various mechanical transmission components.
Description of drawings
Accompanying drawing is the utility model hydrodynamic unit and mechanical transmission component blocking test platform structural representation.
Embodiment:
As shown in drawings, hydrodynamic unit and mechanical transmission component blocking test platform comprise engine 1, gear case 2, torque speed sensor 3, by test specimen 4, gear governing box 5, Cardan shaft 6, loader 7; Engine 1 is connected with gear case 2 by ring flange, gear case 2 is connected with torque speed sensor 3 by ring flange, torque speed sensor 3 by ring flange be connected by test specimen 4, be connected by the input shaft of ring flange by test specimen 4 with gear governing box 5, the output shaft of gear governing box 5 is connected with loader 7 by Cardan shaft 6, loader 7 is connected with gear case 2 by ring flange, forms a closed system.Loader 7 is a slip clutch, and slip clutch is the secondary composition of multiple-piece wet friction.Can be fluid-flywheel clutch and gearing thereof by test specimen 4; Also can be fluid torque-converter and wheel box thereof by test specimen 4.
If by test specimen 4 only is fluid-flywheel clutch, in this case, loader 7 can omit, and the output shaft of gear governing box 5 is connected with gear case 2 by Cardan shaft 6.
Under the duty, after engine 1 starts, input shaft by gear case 2 drives torque speed sensor 3, transmission of power is given by test specimen 4, driven loader 7 by test specimen 4 driven gear governing boxs 5 through Cardan shaft 6, loader 7 is given gear case 2 with transmission of power, finish a power cycle, go round and begin again successively, because the loss of mechanical efficiency in the course of the work, engine 1 needs to replenish the power of institute's loss.
