Abstract
This utility model is related to a kind of new power takeoff assay device, it includes motor, variator, power takeoff, oil pump, the power transmission shaft of the motor is coaxially connected with the input shaft of variator, power takeoff driving gear is meshed with transmission countershaft gear, and power takeoff rear end is coaxially connected with oil pump drive shaft by power transmission shaft.The device oil pump instead of motor and load as rear end, and oil pump cost is much smaller than motor, and oil pump is co-axially mounted with power takeoff and is more prone to, and greatly reduce equipment cost and human cost required for test.
Description
Technical field
This utility model is related to a kind of new power takeoff assay device.
Background technology
Due to the fast development in Chinese Business Car market, some power takeoff manufacturers professional in the world, such as：Italian English
Te Papu has also logged on China.Domestic power takeoff is most to be used on dumper, so the requirement to power takeoff is relatively simple.
In Europe, North America, as requirement of the special purpose vehicle to power takeoff is very high, the design of power takeoff manufacturer is more professional, more various.With
The development of time, the power takeoff of China also can be more and more diversified, specialized.
At present, for the test of power takeoff does not have special testing equipment, testing crew generally to be filled with the test of variator
Standby built again repacking.But as a lot of equipment have coaxial requirement, cause equipment movement installation difficulty.
In addition, at present for the test of power takeoff generally adopts front end Motor drive, the mode of rear end motor loading.This
Mode requires that front-end driven motor and rear end loading motor coaxially work.But the position due to power takeoff in actually building is closed
System, causes installation difficulty big, and in process of the test, rear end motor is constantly in working condition, causes the consume of electric energy serious,
And the high cost of motor.
Therefore need badly in the middle of prior art and want a kind of new technical scheme to solve these problems.
Content of the invention
The purpose of this utility model, it is intended to which to build big difficulty, high cost, electric energy loss serious in order to solve existing testing equipment
Etc. technical problem, propose a kind of little difficulty, low cost, energy-conservation and power takeoff closer to practical application built and test and fill
Put.
A kind of power takeoff assay device of this utility model, includes motor, variator, power takeoff, oil pump, the motor
Power transmission shaft is coaxially connected with the input shaft of variator, and power takeoff driving gear is meshed with transmission countershaft gear, power takeoff
Rear end is coaxially connected with oil pump drive shaft by power transmission shaft.
Pressure regulator valve is provided with the petroleum pipeline of the oil pump, and pressure regulator valve is installed above pressure gauge.
This utility model provides a kind of novel test device of power takeoff, and the device oil pump instead of motor as rear
End loading.Oil pump cost is much smaller than motor, and oil pump is co-axially mounted with power takeoff and is more prone to, and greatly reduces needed for test
The equipment cost that wants and human cost.In addition oil pump is without external power supply, it is to avoid the loss of electric energy.This utility model one kind takes
The novel test device of power device, is a kind of energy-conserving and environment-protective and the novel test device closer to practical application.
Description of the drawings
Fig. 1 is a kind of structural representation of power takeoff assay device of this utility model.
Specific embodiment
The embodiment for being given below in conjunction with the accompanying drawings is described in further detail to this utility model.
With reference to Fig. 1, a kind of power takeoff assay device includes motor 1, variator 2, power takeoff 3, oil pump 4, the motor
1 power transmission shaft is coaxially connected with the input shaft of variator 2, and variator 2 is fixedly connected by housing with 3 front end of power takeoff, power taking
Device driving gear is meshed with transmission countershaft gear, and 3 rear end of power takeoff is coaxially connected with 4 drive shaft of oil pump by power transmission shaft
Connect.
Pressure regulator valve 5 is provided with the petroleum pipeline of the oil pump 4, and pressure regulator valve 5 is installed above pressure gauge 6.In figure, 7 are oil
Case.
A kind of working method of the novel test device of power takeoff of this utility model is as follows：
The oil pump 4 of suitable types first according to the moment of torsion of power takeoff 3 to be tested, is selected, after installation and debugging are good, is started
It is powered to motor 1, the power transmission shaft of motor 1 drives variator 2 to rotate, and variator 2 drives power takeoff 3 to rotate, and power takeoff 3 drives oil
Pump 4 is rotated, and starts the cycle over the oil in oil pump.The pressure value for adjusting pressure regulator valve 5 can be shown by pressure gauge 6.Testing crew
By adjusting pressure regulator valve 5, the pressure size of control oil pump 4, to load to power takeoff 3.The model of oil pump 4 can pass through test
The difference of 3 moment of torsion of power takeoff is selecting.
