A1 Cardone constant-velocity axle Joints is the drive axles on your car that contains two CV Joints. There are two different types of CV Joints and they are used on the axle inyour Acura TL. At the inboard end, where the axle shaft only moves up and down with the movement of the suspension, a Tripod Joint is used. This has a three pointed yoke attached to the axle shaft, which has barrel shaped rollers on the ends. These fit into a cup with three matching grooves, attached to the differential. Since there is only significant movement in one axis, this simple arrangement works well. The outboard end of the constant-velocity axle shaft, a slightly different unit is used. The end of the constant-velocity axle is splined which fits into the outer Joint and is typically held in place by a clip. The cage is spherical but with ends open, and it typically has six openings around the perimeter.The rubber boots covering the Joints fail from age or are torn by road debris, letting the grease out and dirt and water in.If a damaged boot caught early, simply replacing the constant- velocity axle Joint boot and repacking the constant-velocity axle Joint with fresh grease may fix the problem. If you continue driving with the broken boot the constant-velocity Joint or a whole drive shaft will need to be replaced. In the worst case the constant- velocity axle Joint may completely come apart. Approximately 300 million constant-velocity axle Joints are sold throughout the world every year, comprising a market of over $6 billion. Torvec's spherical gearing was invented for use in there own pumps and motors, in doing so, they found an alternative use as an automotive constant-velocity Axle Joint.This Torvec constant-velocity Joint, which uses spherical gears, is interchangeable with existing constavt-velocity Axle Joints, and has lower weight and manufacturing cost than current constant-velocity Axle Joints.The Torvec constant-velocity Joint enjoys world-wide patent protection. Improvements continue to be pursued.
