Hunter Engineering Others Driver Download 1. A plate brake tester for testing braking characteristics of brakes of a vehicle having brakes comprising:

at least a first pair of weight bearing plates and a second pair of weight bearing plates, each weight bearing plate being suitably sized to receive thereon at least one wheel/tire assembly of a vehicle as a vehicle is driven over the plates, the plates of each pair being substantially parallel to each other, said first pair of weight bearing plates being spaced from the second pair of weight bearing plates a predetermined distance along a predetermined direction of travel, said predetermined distance being approximately thirty feet;

sensors for sensing, for each plate, a brake force applied by a brake associated with the wheel/tire assembly passing over said plate and for sensing the dynamic weight of the wheel/tire assembly on each plate during braking; and

control circuitry operatively connected to the sensors for determining from the brake force and the sensed dynamic weight braking characteristics of the brakes of the vehicle under test.

2. The plate brake tester as set forth in claim 1 wherein the sensors include at least one load cell for each plate.

3. The plate brake tester as set forth in claim 1 wherein the length of said plates, measured along the direction of travel, is approximately 36'.

4. The plate brake tester as set forth in claim 1 wherein each weight bearing plate has a width, measured perpendicularly to the direction of travel, which exceeds the length of said plate.

5. The plate brake tester as set forth in claim 4 wherein said width is approximately 48'.

6. The plate brake tester as set forth in claim 1 wherein the plates are all disposed on a test lane, further including means for signalling to an operator to drive a vehicle onto the test lane.

7. The plate brake tester as set forth in claim 6 wherein the signalling means is manually controlled.

8. The plate brake tester as set forth in claim 6 further including visual means for signalling the operator to apply the brakes of the vehicle.

9. The plate brake tester as set forth in claim 8 wherein the visual means are operable in response to detection of the presence of the vehicle at a predetermined position along the test lane.

10. The plate brake tester as set forth in claim 6 wherein the vehicle is a multi-axle truck and the test lane is sufficiently long to allow the truck to decelerate from approximately 30 mph to a stop, the plates being disposed along the test lane such that the truck is decelerating as each wheel/tire assembly passes over at least some of the plates.

11. A method of testing braking characteristics of brakes of a vehicle having brakes, comprising the steps of:

driving a vehicle down a test lane in which are disposed first and second pairs of weight bearing plates, said first and second pairs of weight bearing plates being separated along the test lane a predetermined distance which is substantially greater than twenty feet;

applying brakes of the vehicle to decelerate the vehicle as wheels of the vehicle are passing over the weight bearing plates;

sensing a brake force applied by the brakes and the dynamic weight of the vehicle by sensors associated with said weight bearing plates; and

determining braking characteristics of the brakes of the vehicle under test from the brake force and the dynamic weight.



12. A method of testing braking characteristics of brakes of a vehicle having brakes, comprising the steps of:

driving a vehicle down a test lane in which are disposed first and second pairs of weight bearing plates, said first and second pairs of weight bearing plates being separated along the test lane a predetermined distance which is substantially greater than the nominal diameter of the vehicle wheels;

applying brakes of the vehicle to decelerate the vehicle as wheels of the vehicle are passing over the weight bearing plates;

sensing a brake force applied by the brakes and the dynamic weight of the vehicle by sensors associated with said weight bearing plates; and

determining braking characteristics of the brakes of the vehicle under test from the brake force and the dynamic weight;

wherein the first and second pairs of weight bearing plates are separated along the test lane a distance of approximately thirty feet.
