Definitions
- This invention relates to a constant velocity joint for use in a motor vehicle. More particularly, this invention relates to an encapsulated spring for the constant velocity joint.
- Constant velocity joints have been used in the transportation industry for years.
- Plunge joints have a movable center of rotation and are somewhat limited in their angular capability (20°-25°). These joints are usually found at the differential end of front wheel drive vehicles. The angular and plunging capabilities accommodate suspension movement, engine movement and center line changes induced by the geometry of the suspension system during suspension movements.
- a typical front wheel drive vehicle has a plunge joint connected to a fixed joint by an interconnecting shaft
- This combination of joints is referred to as a halfshaft
- a similar configuration of halfshaft can be found on most rear wheel drive vehicles with independent rear wheel suspension. The only difference in a rear wheel drive vehicle is that the wheels do not normally accommodate steering.
- it is possible to use two plunge joints for each halfshaft When using two plunge joints, a mechanism is necessary to position the interconnecting shaft with respect to the two plunge joints. Generally, this is accomplished by providing centering springs between the interconnecting shaft and the plunge joints.
- propshafts which rotate at engine speed, are used to carry the power from the transmission or transfer case to the front or rear differentials.
- the engine speed is normally greater than the wheel speed due to differential and transmission gear ratios.
- Propshafts also utilize constant velocity joints to provide the required angular and plunge travel When two plunge joints are used in a propshaft arrangement the arrangement requires a mechanism to center the interconnecting shaft The mechanism is similar to those used in independent rear wheel drives. As mentioned above, centering springs may be used to accomplish the centering.
- a centering spring includes a coil spring located in a pocket of the plunge joint outer race. One end of the coil spring rests against the bottom of the pocket and the other end is attached to a metal cup. The metal cup bears against the interconnecting shaft.
- An identical configuration is used in the joint at the opposite end of the halfshaft or propshaft The interconnecting shaft is free to float between the two plunge joints, however, it will always be positioned by the reaction of the two centering springs to a position which equalizes the preload on both springs.
- the present invention provides the art with an encapsulated spring for use in a constant velocity joint.
- the encapsulated spring of the present invention provides more rigidity to the system. Thus centrifugal force has less effect on the system during the balancing operations.
- the present invention also provides a centering spring which is less likely to disengage during joint operation.
- Figure 1 is a side elevation view partially in cross section of a constant velocity jointed propshaft assembly including an encapsulated spring in accordance with the present invention.
- Figure 2 is a side elevation view partially in cross section of the encapsulated spring assembly in accordance with the present invention.
- Figure 3 is an enlarged cross section view of a first cylindrical housing portion as in Figure 2.
- Figure 4 is an end elevation view of the first cylindrical housing portion shown in Figure 3.
- Figure 5 is an enlarged cross section view of a second cylindrical housing portion as in Figure 2.
- Figure 6 is an end elevation view of the second cylindrical housing portion shown in Figure 5.
- a constant velocity jointed propshaft assembly is shown in Figure 1 and is designated by reference numeral 10.
- the constant velocity joint shown for illustration purposes is of the double offset design. Those skilled in the art can take the invention herein described and apply it to other types of constant velocity joints.
- the propshaft assembly 10 has a pair of constant velocity joints 20 connected by an interconnecting shaft 22.
- Each constant velocity joint includes an inner race 24, a cage 26, a plurality of balls 28, and an outer race 30.
- An encapsulated spring assembly 34 is maintained in each joint 20.
- the outer race 30 has an inner wall surface 31 which defines an inner cylindrical chamber 32.
- a retaining groove 33 is machined into the inner wall surface 31 to maintain the encapsulated spring assembly in the joint as will be explained herein.
- the encapsulated spring assembly 34 is located in chamber 32 and bears against the outer race surface 36 and the interconnecting shaft surface 38.
- the encapsulated spring assembly 34 includes a first cylindrical housing portion 40, a second cylindrical housing portion 42 and a coil spring 44.
- the first cylindrical housing portion 40 has a cylindrical outer wall 46 defining an internal cavity 48.
- a flange 50 extends radially inward from the housing outer wall 46 to define a circular aperture 52.
- the aperture 52 enables the second housing portion 42 and coil spring 44 to pass through.
- the flange 50 provides a stop for the second housing portion 42 to prohibit further axial movement of the second housing portion 42 through the aperture 52.
- a plurality of slots 54 and a plurality of tabs 56 are stamped out of wall 46.
- the tabs 56 extend radially outward from the wall 46 at an angle less than 90° with respect to the wall 46 as shown in Figures 3 and 4.
- the angular tabs 56 cooperate with the retaining groove 33 to maintain the spring assembly 34 within the chamber 32.
- the tabs 56 are flexed inwardly to pass into the chamber 32 and rebound into the groove 33 to retain the housing as seen in Figure 1.
- the second cylindrical housing 42 has a cylindrical outer wall 62 defining an internal cavity 64.
- a flange 66 extends radially outward from one end of the housing wall 62.
- the other end of the housing wall 62 is closed and has a partial spherical surface 68 as seen in
- the coil spring 44 is designed to be slightly longer than both the housing portions
