There is a maintenance need for every vehicle at some point. Immediate attention is often required to check for wear. Sometimes it is the regular repair that is needed for the proper functioning of the car. It is very important to replace worn and damaged parts to prevent further damage to the car.
If you want to see your vehicle running smoothly, you definitely need auto test products with the latest technologies and services. There are a number of manufacturers of autotest products that meet the highest standards in terms of quality, durability, reliability and safety. These are definitely the drivers of any successful automotive industry, representing the basic characteristics that come to mind of any customer.
A very popular auto test product used is the roller brake tester, widely used to calculate braking efforts and vehicle efficiency. A roller brake tester consists of a chassis with a driven roller system. The other two brake testers are the portable decelerometers and the plate brake testers which have 2 parallel measuring plates.
A Roller Brake Tester (RBT) allows the dynamic evaluation of the braking system of a motor vehicle, in stationary and controlled conditions. Using RBT, the brake force for each wheel, the air pressure in the line and in the wheel chamber, the imbalance in all the axles, test the emergency brakes and the parking brakes, in addition to comparing the force of brake with air or hydraulic pressure, pedal pressure and display. braking force are displayed in due time. RBT also allows to find Ovality and Cracking in drums as well as Warping of disc brakes.
This type of test is performed on a mechanical floor unit that contains electric motors, brake force transducers, two independent sets of three gauge rollers along with additional safety sensors.
Correct Brake Testing helps the technician to determine the performance of the brakes, in addition to effectively and efficiently locating possible failures in the braking system that often go unnoticed.
It is imperative to reduce the rolling resistance of the wheels. Approximately 40% of total fuel consumption is attributed to exceeding rolling resistance and is due to potential component wear. It should be noted that the ideal rolling resistance should be 3-4% of the individual weight of the wheel.
Some of the common problems associated with rolling resistance include:
- Brake pad dragging drum/disc
- Foreign matter rubbing on the wheel
- pressure valve leak
- under inflated tires
- tight bearing
Organizations that primarily use roller gauges include:
- Manufacture of heavy vehicles on production lines
- Manufacture of heavy vehicles under investigation
- Heavy Vehicle Repair Workshops
- Heavy vehicle inspection stations
- Bus and coach companies
- Mining companies
- airlines
- Road Police / Armed Forces
Roller Brake Testing helps to display and measure the following values:
- Crack pressure and threshold
- Braking force at each wheel
- Time lapse / reaction time
- PM Service Line Pressure
- Rolling resistance Px
- Ovality/Disc Depletion
- Cylinder pressure Px
- Balance in %
- axle weight
- Efficiency
- Graphic presentation of test results.
The benefit of performing the roller brake test lies in presenting all the key values at the same time.
