Put a straight edge from the belt on the drive pulley to. You also have to check the belt deflection. It results in a network of inner materials in the form of rigid cords that bond to the tread and greatly reinforce the tire carcass. Once the pulley is off take the belt off the driven pulley then you can reinstall the new belt. Rubber companies in Akron came together and quickly shifted their production and development efforts to synthetic rubber and manufactured enough to supply the U.S. Their construction consists of two steel belt layers and two or more layers of nylon under the tread. When the belt moves, it creates a V-shape in the tire tread. Belted tires are good in the sense that they promote a strong structure. This will cause excessive slip and loss of steerability on the front of the vehicle and less braking on the rear.ĭuring a launch the rears will think they are going slower than they really are so they will slip more. Belt shift in tires is caused by the belt’s movement from the wheel’s circumference to the spoke spacing. This will make the front wheels brake harder to try to get to this incorrect speed and will make the rear wheels brake less because they think are going slower than than they really are. Now, that reference speed is constantly recalculated every 12.5ms and is used during all abs, traction and stability events.ĭuring a stop the incorrect reference speed will tell the vehicle it is going slower than it really is. Now same thing in modified car with rear tires 10% larger This one calculation is critical to all these systems. First, on our list, we have the Allen Sports Deluxe 2-Bike Rack. This is a rather complex calculation and also uses othe vehicle sensors besides wheel speeds. So, if you do happen to have a spare tire attached to the back of your vehicle, check out our best spare tire bike racks. Tire of a car replaced with Donut Spare Tire The tire of the vehicle can flat out due to many unexpected reasons, a puncture being the most common one. This reference speed is calculated by using all 4 wheel speeds The calculation also knows which wheels are driven and which wheels are non driven. A donut spare tire, also commonly known as temporary used spare tires (TUSTs) or space-saver tires are small, compact, and lightweight tires designed for temporary use in case you get a flat tire. That is used as a reference point to controll how much slower (during an abs stop) or how much faster (during a traction control launch) the wheels are going than the actual vehicle speed. I have worked on development and validation for ABS, Traction Control and Stability since before they were available equipment on most cars (AKA the 80s)Īll of these systems work by looking at all 4 wheel speeds to try to determine how fast the vehicle is going. ![]()
