Description
Technical field
The present invention relates to the tablet anti-force type automobile brake verifying benches in Automobile Braking Force Detecting field.
Background technology
Now society development in, for automotive safety, environmental protection, it is energy saving be development of automobile technology three big themes, automobile into
It is during the detection of the security performance of automobile and its important before row dispatches from the factory, automobile in the process of moving, technology status and performance
It gradually degenerates with the increase of operating range, it may appear that braking ability declines, and economy is deteriorated, and what security reliability reduced asks
Topic, these problems seriously affect the performance of the security performance and economic benefit of automobile, therefore the braking forces measuring of automobile is shown
It obtains particularly important.
There are two types of existing automobile brake verifying benches, the first is drum reaction type automobile brake verifying bench, it by
The drum apparatus of carrying, the main motor for driving roller rotation and reducing gear, braking force measuring system etc., measuring principle is：
When vehicle is braked, the wheel being on drum apparatus can be to the power in the one despining direction of roller being rotating, the reaction
Power can reflect the size of brake force.Drum reaction type automobile brake verifying bench has the following problems：Due to automobile forum
With 2.5km/h linear velocities and two curved face contacts of two carrying rollers, automobile brake detection indicating value stepping and automobile axle load, rolling
Cylinder, which slides attachment coefficient, relation, also with the air pressure of the diameter, tire of tire, diameter of cylinder, centre of the drum away from, main driven roller
The Form and position error of difference in height and roller has much relations, that is to say, that and the impacted factor of braking forces measuring indicating value is more, and with
The actual operating mode of vehicle is not inconsistent, therefore is difficult the braking ability for accurately measuring automobile.
It is for second tablet anti-force type automobile brake verifying bench, " the motor as disclosed in Chinese patent CN101476957B
The plate type braking force measuring apparatus of automobile of driving ", the driving mechanism including antiskid plate and the back-and-forth motion of Anti-slip regulation plate,
Braking force measuring apparatus further includes force cell.During inspection, the pressure wheel of automobile is fixed automobile on antiskid plate,
Driving mechanism Anti-slip regulation plate level moves, and after antiskid plate drives vehicle wheel rotation, wheel braking, force cell measures antiskid plate
The reaction force being subject to embodies the brake force of wheel, uses flat support, for traditional cylinder support, closer to vapour
The actual travel road conditions of vehicle, but current flat automobile brake verifying bench there is problems：Anti-skidding tablet is facing forward
Drive vehicle wheel rotation is realized in translation, and due to needing speed when examining, this results in anti-skidding tablet to be also required to this in 5 ~ 10km/h
The speed of sample, anti-skidding tablet need very big shift motion that could meet examination requirements, cause entire verifying bench and anti-skidding flat
Plate is all very big, takes up a large area and cost is higher.
The content of the invention
It is of the prior art to solve it is an object of the invention to provide a kind of tablet anti-force type automobile brake verifying bench
