According to the invention, an input terminal of the drive axle adjusts input torque through a variable frequency motor and a frequency converter, and indication values of adjusting are displayed through the torque speed sensor and the torquemeter; the output terminals adjust drive axle load torque through the magnetic powder brake and a controller, and indication values of adjusting are displayed through the torque sensor and the torquemeter.
Description
Technical field
The present invention relates to a kind of load test stand of drive axle, particularly relate to a kind of load test stand of tractor drive axle.
Background technology
At present; The load test method of tractor drive axle; Generally the drive axle output terminal is connected with the low speed end of cylinder gear speed reducer, the drive axle input end is connected with motor, utilizes the speedup of cylinder gear speed reducer reverse drive to be reached for the purpose of drive axle load.Such test method can't directly show load torque, can't carry out adjustable operation to load torque.
Summary of the invention
It is directly perceived, accurately that the object of the invention just provides a kind of load data, uses simple, conveniently, can calculate the drive axle load test stand of drive axle transmission efficiency.
To achieve these goals; The present invention is provided with drive axle on the testing table pedestal; The drive axle input end connects with torque rotary speed sensor and variable-frequency motor through second shaft coupling and first shaft coupling; Torque rotary speed sensor is connected with tachometer torquemeter through lead, and frequency converter is connected with variable-frequency motor through lead, and drive axle two output terminals connect with torque sensor and magnetic powder brake through the 3rd shaft coupling and tetrad axial organ; Magnetic powder brake is connected with controller through lead, and torque sensor is connected with torductor through lead.
Through above setting, the input end of drive axle of the present invention is regulated input torque through variable-frequency motor and frequency converter, and the indicating value of adjusting shows through torque rotary speed sensor and tachometer torquemeter; Output terminal is regulated the drive axle load torque through magnetic powder brake and controller; The indicating value of regulating shows through torque sensor and torductor.
Description of drawings
