Seat is correspondingly arranged up and down with location-plate.This utility model motor rear axle fictitious load noise measuring platform provides the benefit that, logical
Cross the setting of said structure, can be on streamline, analog detection goes out motor rear axle in the unloaded and situation of load 500 kilograms
Lower will produce the noise of how many decibels, if there is abnormal sound；Concrete function is as follows: stress test stalling current size；It is poor to test
Whether speed device operation process there are abnormal voice or noise；Axiality when the overall back axle of test runs and stability；After test
Low speed and stationarity at a high speed and braking in bridge running；Whether metaboly is had during test back axle load-bearing.
Preferably, described mobile cylinder block is provided with two, and one of them moves cylinder block and is positioned at the surface of location-plate,
Convenient replacement.
Preferably, the outside of one of them testboard riser seat is provided with downward floating seat, described downward floating seat with stop
Axletree connects.In order to adjust the upper-lower position of brake axle, in order to be applicable to detect the motor rear axle fictitious load of different style
Noise.
Preferably, the outside of two described testboard riser seats is provided with bridge wheel movable bearing support.Scalable, the suitability
By force.
Preferably, the outside of two described testboard riser seats is provided with lower bent plate, and described lower bent plate is positioned at bridge wheel and lives
The top of dynamic bearing.
Preferably, described axle being provided with sinker, the upper surface of described sinker is provided with cleek.
Preferably, described sinker is between two described mobile cylinder blocks.
