Description
Technical field
The utility model is a kind of engine torque extracting machine test unit.
Background technology
In recent years, China's special car fast development increased day by day to the demand of automobile power transmission.Particularly cement stirring conveying vehicle, need the continuous working long period, will select that power is large, power takeoff that can continuous operation.Engine torque extracting machine is conducive to arrangement, and becomes the first-selection of these vehicles.
Concrete mixing and transporting car adopts the engine torque extraction mode, and power takeoff takes out engine power, is converted into hydraulic energy through pump, then is output as rotating speed and moment of torsion through motor, provides power for churn rotates.
16 ~ 20m
3The large-sized concrete agitator truck enjoy the user to favor, engine torque extracting machine need to be exported larger moment of torsion, engine torque extracting machine and applying working condition do not mate and cause engine torque extracting machine serviceable life to shorten, even cause serious quality accident, brought inconvenience for repacking producer and user and cause economically loss.For these situations, checking running is reliable, and the power takeoff device that can continue to export high pulling torque has caused people in the industry's concern.
Summary of the invention
The utility model is for the deficiencies in the prior art, a kind of engine torque extracting machine test unit is provided, the utility model assembling is convenient, reliability is high, can carry out verification experimental verification according to the actual operating mode of power takeoff, has improved the reliability of power takeoff device and associated gear gear train.
The utility model is realized by following technical measures: a kind of engine torque extracting machine test unit, comprise engine, engine torque extracting machine, support, dynamometer machine, transmission shaft, air compressor machine charger, air compressor machine add load control, described engine is rack-mount, air compressor machine gas outlet on described engine is connected with the air compressor machine charger, described engine torque extracting machine is connected with transmission shaft by shaft coupling, described transmission shaft is connected with dynamometer machine, and described engine torque extracting machine and dynamometer machine are arranged on same axis.
Concrete characteristics of the present utility model also have, and above-mentioned shaft coupling is the duplex axial organ.
The beneficial effects of the utility model are: the utility model assembling is convenient, reliability is high, can carry out verification experimental verification according to the actual operating mode of power takeoff, has improved the reliability of power takeoff device and associated gear gear train.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, engine, 2, engine torque extracting machine, 3, transmission shaft, 4, shaft coupling, 5, dynamometer machine, 6, the air compressor machine add load control, 7, the air compressor machine charger, 8, support.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, this programme is set forth.
As accompanying drawing, a kind of engine torque extracting machine test unit, comprise engine 1, engine torque extracting machine 2, support 8, dynamometer machine 5, transmission shaft 3, air compressor machine charger 7, air compressor machine add load control 6, described engine 1 is arranged on support 8, air compressor machine gas outlet on described engine 1 is connected with air compressor machine charger 7, described engine torque extracting machine 2 is connected with transmission shaft 3 by shaft coupling 4, described transmission shaft 3 is connected with dynamometer machine 5, and described engine torque extracting machine 2 is arranged on same axis with dynamometer machine 5.Wherein, shaft coupling 4 is the duplex axial organ.
before adopting this device experiment, need to adopt the installation form of conventional engine to test acquisition to engine boundary Control condition, be that engine is first tested a plurality of operating points of engine on the test-bed of routine, cold rear intake air temperature in the measurement engine, exhaust back pressure, the correlation parameters such as cooling water inflow, and then utilize these correlation parameters to be applied in the technical program, by the air compressor machine add load control, a plurality of operating points are tested, obtain the test boundary condition of engine torque extracting machine, select at last suitable engine torque extracting machine, specifically implement according to utility model.
Consider that trucd mixer drives the variation that load change is mainly manifested in moment of torsion, power takeoff is with different its change in torque of churn operating mode, the control program of test can be compiled and edit operating condition of test according to the operating mode of trucd mixer power takeoff actual motion, and the examination operating mode is returned to different operating modes and tested by reinforced program, working procedure, commutation operation, discharging operation, zero load; Charger with air compressor machine can keep synchronizeing with engine operating condition simultaneously, has jointly realized stand control.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
