Description
Technical field
Technical field of automobile detection is the utility model is related to, is a kind of guiding dress of flat board brake test bench specifically
Put.
Background technology
When examining car using flat board brake test bench, automobile is travelled with certain speed, when 4 wheels all reach platen, brake.
Vehicle drives upper platen also to travel forward, dynamometry is provided between upper platen and underframe horizontal direction because inertia moves forward
Sensor, upper platen travels forward so that force cell deforms, and measures the active force forward of upper platen.According to upper platen
Force analysis, in the horizontal direction, wheel act on the power of upper platen（That is, power-braking that upper platen is acted on wheel
Power）It is exactly the power of upper platen effect on a sensor.Upper platen allows for moving forward and backward in the horizontal direction（Displacement is very
It is few, it can mainly cause force cell deformation）, can not laterally there is movement.
Flat board brake test bench guiding mechanism uses roller or bearing guide frame, roller or bearing be arranged on roller mount or
