~ TEUESCOPIC TRIPOD UNIVERSAL JOINT
Background of the Invention The im~ention relates to universal joints and, more particularly, to a telescopic tripod ~ univcasal joint.
Tripod constant velocity universal joints have been used by the transportation industry for numerous years. A typical tripod joint is shown in U.S. Patent 4,773,890 issued to Iwasaki et al. on September 27,1988.
This joint consists of an outer race formed with three longitudinal chambers.
A
spider assembly is disposed within each chamber. lounoaled on each of the spider trunnions is a roller. Interposed between each roller and the respective trunnioa is a phuality.of needle roller bearings.
While this joint has ptowea to be an effective design, it has several disadvantages.
One disadvantage is during operation of the tripod joint at an angle, the joint produvea a !5 third order a~dal cyclic vibration known as "shudder". This shudder phenomenon often times is felt by the driver and passengers of the vehicle.
Shudder is caused by sliding rather than rolling of the rollers when the joint is rotating at an angle. While at as angle, the plane of rotation of each roller is skewed relative to its respective outer racx track. This causes a combination of rolling and sliding of the roller on its rapoctive track as the spider moves aadally relative to the outer race.
This sliding action is the main component produang the third order axial cyclic vibration or shudder. As the angle of the joint increases, there is more sliding and therefore a higher axial load is induced.
There are numerous designs which attempt to minimize the axially induced force.
Iwasaki et a1 patent attempts to reducx this induced load by using angular contact on the tracks. This has the effect of lowering the surface area of contact between the roller and the 'i0 93/02296 ~ ~ ~ ~ ~ ~ ~ PCT/US92/05868 _2_ track. While some reduction in load is possible with this joint, it does not significantly reduce the shudder phenomenon.
U.S. Patent No. 4,619,625 issued to Orain on October 28, 1986 illustrates a triplsn joint which separates the components within the joint which are responsible for angular and aranslatmnal movements While this device is able to significantly rtduce or even eliminate the axially induces! forces in the joint, the design of the joint is complicated and expensive.
Various other patents have approached the problem by going to multiple piece roller assemblies is an attempt to reduce the "shudder" phenomenon.
