Description
Technical field
The invention belongs to gearbox detection fields, particularly relate to a kind of shift performance bench test tooling.
Background technique
In the development process of the product of gearbox, also take an examination while considering that gearbox shifting function is reliable, durable
Consider the excellent degree of gearbox shifting performance, the rapid time is short, shift shock is with small vibration, noise is small such as shifted gears.And current platform
Gearbox shifting function and performance are verified on frame, take gearbox mount scheme is substantially equal are as follows: the hair of gearbox become face and
Rack input motor directly connects firmly.The installation of its advantage is reliable, stablizes, the revolving speed and torque and gearbox of the input of Yi Shixian motor
Input shaft is concentric.But therefore gearbox is caused to connect firmly quality but also gearbox is connected firmly with gantry motor (even) and its floor
It is excessive, to cause during being unable to test analysis gearbox shifting because axial shifting power, input shaft rotating speed are synchronized mutation etc.
FCL transient vibration excitation/noise, so that judging work to the shift performance test of engine bench test generates significant impact.
There are two types of installation condition when front gear box is in bench test is usual:
The first is that input and output motor is connected with the bottom plate of rack using bolt and pressing plate on test-bed, then
Become face by the hair that bolt connects firmly gearbox and rack inputs motor.The vibration pasted when test by transmission housing external surface
Acceleration transducer or sound Mike acquire vibration/noise amplitude and frequency, to judge the correlated performance of shift process.
Second is that the hair change face that gearbox is connected firmly by bolt and rack input motor, is then by main component
The support frame of liquid/gas pressure, stiffness spring etc. realizes " being flexible coupling " of input motor+transmission assembly and rack bottom plate.When test
The vibration acceleration sensor pasted by transmission housing external surface or sound Mike acquire vibration/noise amplitude and frequency
Rate, to judge the correlated performance of shift process.
First method makes that gearbox and rack input motor and rack floor connects firmly, so as to connect firmly quality remote for gearbox
Much larger than gearbox quality itself, thus the abnormal vibrations (noise) generated during being unable to test out gearbox shifting.
Second method gearbox and rack input motor to connect firmly, so as to connect firmly quality excessive for gearbox, thus nothing
Method/can not obviously test out the abnormal vibrations (noise) generated during gearbox shifting.In addition, this method needs root when designing
According to motor+FCL assembly spatial design placement location, to guarantee the static equilibrium state under dynamic of motor+FCL assembly.Cause
This designs different brackets according to different Fulcruns, and no matter bracket selects hydraulic, air pressure or high muscle degree coefficient spring
Which kind of it is flexible coupling Deng, components needed for a whole set of bracket are more, and the key of related hydraulic, air pressure and high muscle degree spring
Parts machining difficulty is big.
