Situation, the measurement hole number of the utility model are preferably three.
Measuring tool of the utility model using photoelectric sensor as measurement third axis roller linear velocity, working principle
Be: the roller group of roller counter-force type automobile brake inspection bench drives automotive wheel rotation, while automotive wheel drives the rolling of third axis
Cylinder rotation.It is averaged the measured hole of circle distribution since third axis roller is equipped with around third axis centre of the drum's axis, third
The rotation of measured hole can form on the photosensor intermittence and block on axis roller, hide in photosensors record specified time
The number of gear, since the quantity of measured hole on third axis roller is it is known that the revolving speed of third axis roller can be calculated, then by known
The diameter calculation of third axis roller go out the linear velocity of third axis roller, since third axis roller and automotive wheel moment keep phase
State is cut, therefore the linear velocity of third axis roller is numerically equal to the linear velocity of automotive wheel.The above process is in the number
According to being completed in processing unit.
It is further used as preferred embodiment, the third axis roller is equipped with smooth outer surface.Third axis roller
Size is much smaller relative to the size of roller group, and third axis roller is roller to be freely rotated, therefore its surface does not need
It is stained with sand.
Referring to Fig. 2, this is the embodiments of the present invention a2, specifically:
A kind of roller counter-force type automobile brake inspection bench, in addition to include above-mentioned intelligent-induction wheel in place and wheel velocity
Photoelectric induction device, further include motor 4, speed reducer 41 and roller group, the roller group includes master rotor 5 and auxiliary cylinder 6, main
Be aligned setting before and after roller and auxiliary cylinder, the third axis roller is located between master rotor and auxiliary cylinder, the shaft of master rotor and
Speed reducer connection, speed reducer are connected to motor, and the speed reducer is equipped with load cell, and the master rotor passes through with auxiliary cylinder
The kind of drive of sprocket wheel chain 7 synchronizes transmission.
The step of roller counter-force type automobile brake inspection bench measurement automobile braking force, is:
1, automobile drives into roller counter-force type automobile brake inspection bench, automotive wheel in place after, automotive wheel rolls third axis
Cylinder is pressed down on lower position；
2, when photoelectric sensor senses third axis roller, roller counter-force type automobile brake inspection bench just initially enters work
Make state, start roller counter-force type automobile brake inspection bench, the roller group of roller counter-force type automobile brake inspection bench starts to drive
Automotive wheel rotation, while automotive wheel drives the rotation of third axis roller；
3, after depressing automobile brake plate, data processing equipment record does not depress the instantaneous speed of automotive wheel before automobile brake plate
Spend V1, data processing equipment record depresses all instantaneous velocitys of automotive wheel whithin a period of time after automobile brake plate later
VΔ；
4, when calculated slip rateWhen in 15%~20% section, data processing equipment
The braking moment of load cell on speed reducer at this time is recorded, the braking moment is the maximum braking force of automobile, is closed later
Motor, detection terminate.
