Technical field
The utility model relates to a kind of wheel box test unit, particularly a kind of gearbox gear-shift process testing device.
Background technology
In known public technology, test method to the hydraulic mechanical transmission box gearshift procedure is: under constant test input speed, load inertia load at gear box output end, the variation of measuring wheel box output torque just can calculate the shifting shock degree of wheel box.Oily temperature to torque converter in entire test has strict requirement, test method for oil supply system and wheel box integral type, the oily temperature of torque converter can only heat up by loading, if change inertia load again after heating up, the oily temperature of torque converter just is difficult to maintain in the required test temperature scope.
The utility model content
The purpose of this utility model is that a kind of control of being convenient to oil temperature in the process of the test will be provided, and improves the gearbox gear-shift process testing device of test efficiency.
The technical scheme that its technical matters that solves the utility model adopts is: this test unit comprises interchange loading motor (1), input torque speed probe (2), torque converter transmission assembly (3), output torque rotary speed sensor (4), six grades of many grades of casees (5), exchange loading motor (6) and shift control handle (7), exchange loading motor (1), input torque speed probe (2), torque converter transmission assembly (3), output torque rotary speed sensor (4), six grades of many grades of casees (5) with exchange loading motor (6) and be linked in sequence, on torque converter transmission assembly (3), be connected with shift control handle (7).
Beneficial effect, owing to adopted such scheme, tested gear box output end connects many gears mechanical gear box and loading equipemtn, utilize loading equipemtn that wheel box is heated up, gearshift procedure institute heat requirement load is utilized the moment of inertia of loading equipemtn self and many gears mechanical gear box to be complementary and is obtained, utilize the moment of inertia of loading equipemtn self and the inertia loading systems such as inertia load replacement inertial flywheel group that many gears mechanical gear box is complementary and obtains, saved the time of changing and debugging inertia load in the process of the test, be convenient to the control of oil temperature in the process of the test, improve test efficiency, reached the purpose of this utility model.
Description of drawings
Fig. 1 is the structural drawing of the utility model hydraulic mechanical transmission box testing experiment stand.
Among the figure, 1, exchange loading motor; 2, input torque speed probe; 3, torque converter transmission assembly; 4, output torque rotary speed sensor; 5, six grades of many grades of casees; 6, exchange loading motor; 7, shift control handle.
Embodiment
Embodiment 1: this test unit comprises and exchanges loading motor 1, input torque speed probe 2, torque converter transmission assembly 3, output torque rotary speed sensor 4, six grades of many grades of casees 5, exchanges loading motor 6 and shift control handles 7, exchange loading motor 1, input torque speed probe 2, torque converter transmission assembly 3, output torque rotary speed sensor 4, six grades of many grades of casees 5 and exchange loading motor 6 and be linked in sequence, on torque converter transmission assembly 3, be connected with shift control handle 7.
Among Fig. 1, the hydraulic mechanical transmission box test-bed, wherein power source and loading equipemtn are the ac variable frequency speed regulation motor, rotating speed of motor and torque can be carried out permanent rotating speed and permanent torque adjustment by frequency conversion equipment, for output characteristics and the loading equipemtn that makes tested wheel box is complementary, series connection gear mechanical gear box more than between tested wheel box and loading equipemtn.The starting characteristics test system, increase the torque of loading equipemtn gradually, the working oil temperature of tested wheel box raises gradually, when reaching the test temperature of test request, conventional test methodologies will be removed many gears mechanical gear box and loading equipemtn, change inertia loading systems such as inertial flywheel group, improved procedure of the present utility model is: utilize one of them gear of self moment of inertia of loading motor and many gears mechanical gear box to be complementary and obtain one and the immediate inertia load of test demand moment of inertia, in process of the test, loading motor is in halted state.
