Abstract
The CV joint removal tool's clamps surround an axle proximal to the CV joint to be separated from the axle. The tool clamps onto the axle and applies a constant axial force to separate the two CV joint components via the push plate and push rods. Removal of the entire axle assembly is negated, saving parts cost and labor costs. The tool does not require complete drive axle removal, as do other devices attempting the same function. The CV joint removal tool pushes the CV joint and the axle apart, further differentiating from previous methods and devices. The tool utilizes Newton's law of equal and opposite reactions. The key challenge that the CV joint removal tool overcomes is that when CV joints are installed, neither end of the drive axle is accessible.
Claims14
A CV joint removal tool comprising, in combination:
- a pair of parallelepiped like shaped and sized clamps comprising a top clamp and a bottom clamp, each clamp having a top spaced apart from a bottom, a width, and two spaced apart sides;
- a v-shaped groove disposed centrally in the bottom of the top clamp;
- a pair of spaced apart orifices disposed in the top clamp, the orifices passing from top to bottom;
- a pair of spaced apart cylindrical extensions disposed proximal to the top clamp groove;
- a smooth bore passed through the top clamp and longitudinally through each extension;
- a threaded orifice passed through the width of the top clamp, the threaded orifice disposed slightly above one extension;
- a v-shaped groove centrally disposed in the top of the bottom clamp, the v-shaped groove disposed in each of the bottom of the top clamp and the top of the bottom clamp having a first side and a second side disposed at a right angle to the first side, wherein the v-shaped grooves collectively forming a diamond between the top clamp and the bottom clamp upon attachment of the top clamp and the bottom clamp to each other;
- a pair of orifices disposed in the bottom clamp, each orifice passed from top to bottom of the bottom clamp, the bottom clamp orifices selectively aligned with the top clamp orifices;
- a plurality of clamp bolts with nuts selectively fastening the top clamp to the bottom clamp;
- whereby the top clamp and bottom clamps surround an existing axle;
- an extension extended from the bottom clamp directly below the bottom clamp groove;
- a smooth bore passed through the width of the bottom clamp and longitudinally through the extension;
- a threaded orifice disposed through the bottom clamp slightly lateral to the extension;
- a parallelepiped push plate having a like shape and size to the assembled clamps;
- a slot disposed from proximal to the center through to an exterior of the push plate;
- a rounded slot end disposed within the slot;
- whereby the push plate may be substantially centrally and selectively disposed around the existing axle;
- a pair of spaced apart foramen disposed through the push plate, the foramen substantially in alignment with the threaded orifices of the assembled clamps;
- a trio of push rods removably passed through the clamp bores and abutted against the push plate;
- a plurality of removal bolts, one of each removal bolt selectively passed through one of each of the foramen of the push plate and into one of each of the threaded orifices of the clamps;
- whereby a tightening of the removal bolts forces the push rods deeper into the bores.
