Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the present embodiment provides a kind of vehicles to play step gear shifting performance testing device, including speed changer and speed change
The connected transmission shaft 4 of device output shaft 33, the driving motor 1 and number being connected by electromagnetic clutch 2 with transmission input shaft 31
According to Acquisition Processor (not shown) and operation controller (not shown)；Driving motor 1 is to become for simulated engine
Fast device provides power.
Speed changer include derailleur body 32, for realizing speed changer block selecting block selecting manipulator 321 and for realizing
The gear shifting manipulator 322 that speed changer is put into gear；Gear shifting manipulator 322 is equipped with generates the power biography of force value for acquiring to put into gear in the process
Sensor.
Transmission input shaft 31 is equipped with for monitoring the rotating speed coder 311 of 31 revolving speed of transmission input shaft and being used for
The inertia disc 312 of simulated clutch friction plate.
Mass flywheel group 41 is set on transmission shaft 4；Mass flywheel group 41 includes 3 inertia being uniformly mounted on transmission shaft
Flywheel.Mass flywheel group 41 guarantees that 33 revolving speed of transmission output shaft is zero when playing step gear shifting test for providing large inertia.
Electromagnetic clutch 2 is connected by neutral gear position switch 21 with power supply 22；Neutral gear position switch 21 is arranged in speed changer
At 32 neutral gear lamp of ontology.
It puts into gear to leave neutral gear position or pluck gear by moving gear shift manipulator 322 and reaches neutral gear position, open neutral gear position
It closes 21 to be opened or closed, controls the separation and engagement of electromagnetic clutch 2；Specifically:
When gear shifting manipulator 322 is in (plucking gear to return to) neutral gear position, neutral gear position switch 21 is closed, electromagnetic clutch 2
Be powered engagement, and the torque of driving motor 1 is passed to transmission input shaft 31.
When gear shifting manipulator 322 is not in (put into gear and leave) neutral gear position, neutral gear position switch 21 is disconnected, electromagnetic clutch
2 power-off separation, cut off the power transmission of driving motor 1.
