Description
Technical field
The utility model belongs to heavy duty transmission the field of test technology, and in particular to one kind is in heavy duty transmission test macro
Driving head assembly.
Background technique
Heavy duty transmission test macro includes driving head assembly and loading system.Driving head assembly is usually by driving motor, biography
Dynamic case, sensor and shaft coupling composition.Due to sensor and shaft coupling unreasonable allocation, cause driving head assembly length excessive,
And sensor service life is short.
Utility model content
The utility model is intended to provide a kind of heavy duty transmission Test driver head assembly, protects sensor, makes overall structure more
Be it is compact, avoid the too long occupied space of driving head assembly length.
For this purpose, the technology employed by the present utility model is a kind of heavy duty transmission Test driver head assembly, including driving
Head pedestal, and variable frequency drive motors, transmission shaft, deceleration liter torsion biography of the installed in series in order on driving head pedestal from front to back
Dynamic case, system dynamic input test mechanism and transmission shaft support base, system dynamic input test mechanism include from front to back
Sequentially coaxially concatenated drum-shaped tooth type shaft coupling, sensor, drum-shaped tooth type shaft coupling.
Described slow down rises the second output that torsion transmission case is further equipped with a 1:1 transmission ratio as a preferred embodiment of the above solution,
End, and the second output terminal head and first output end be located at slow down rise turn round transmission case the same side, second output terminal head with
Input end coaxial arrangement.The second output terminal head for increasing a 1:1 transmission ratio on transmission case is turned round for high iron teeth slowing down to rise
Box high speed test, expands the scope of application of driving head assembly.
Further preferably, the power of the variable frequency drive motors is 710KW.
The utility model has the beneficial effects that
(1), sensor can twist in heavy duty transmission test process, cannot bend, and concentricity requirement is high,
Flexible drum-shaped tooth type shaft coupling is installed in the two sides of sensor, and front and rear, left and right itself can occur, swing up and down, thus right
Sensor is effectively protected；
(2), driving head assembly integrated installation is on driving head pedestal, convenient for management and maintenance；
(3), drum-shaped tooth type shaft coupling is installed using in driver two sides, keeps overall structure more compact, avoids driving head
The too long occupied space of assembly length, so as to the scope of application of expanding test platform.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged diagram of system dynamic input test mechanism.
Fig. 3 is the state that the utility model is used for the test of heavy-duty car tandem axle.
Fig. 4 is that deceleration rises the second output terminal head for turning round one 1:1 transmission ratio of increase on transmission case for high-speed rail gear-box height
The state of speed test.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1, a kind of heavy duty transmission Test driver head assembly, successively goes here and there by driving head pedestal 1, and from front to back
Join the variable frequency drive motors 2 being mounted on driving head pedestal 1, transmission shaft 5, slow down to rise and turn round transmission case 3, system dynamic input test
Mechanism 4, transmission shaft support base 6 form.Wherein, system dynamic input test mechanism 4 is by sequentially coaxially concatenated drum from front to back
Shape gear coupling 7, sensor 8, drum-shaped tooth type shaft coupling 7 form.
Preferably, slow down to rise and turn round transmission case 3 and be further equipped with the second output terminal head 3b of a 1:1 transmission ratio, this is second defeated
The output of end 3b and first end 3a is located at the same side for slowing down and rising and turning round transmission case 3, second output terminal head 3b and input end out
3c coaxial arrangement.The second output terminal head 3b for increasing a 1:1 transmission ratio on transmission case is turned round slowing down to rise, is used for high-speed rail gear-box
9 high-speed test (HST), the scope of application of expanding test platform, as shown in Figure 4.
In addition, the power of variable frequency drive motors 2 is 710KW.
Fig. 3 show state of the heavy duty transmission Test driver head assembly for the test of heavy-duty car tandem axle, by one
Driving head assembly A, four loading head assembly B compositions.Driving head assembly A is used to simulate the power-driven system of heavy-duty car, adds
Carrier head assembly B is used to simulate the tire of heavy-duty car, and four loading head assembly B respectively correspond jackshaft 10, four on rear axle 11
Tire.System dynamic input test mechanism 4 is inputted for test macro power.
