Abstract

A skateboard truck assembly that eliminates wheel bite without sacrificing the turning responsiveness thereof. The truck assembly includes a plurality of set screws disposed in the ring-shaped member of the hanger adjacent to the kingpin. The longitudinal axis of the plurality of set screws is generally parallel to the axle and generally perpendicular to the longitudinal axis of the kingpin. The distances between the plurality of set screws and the kingpin, adjustable by the user, determines the amount of wheel bite prevention. When the hanger pivots through an angle and causes a set screw to contact the kingpin, further pivoting of the hanger stops. In a further feature the shaft of the kingpin includes a plurality of flat surfaces adjacent to the plurality of set screws.

Claims (44)

1. A skateboard truck assembly comprising:

a kingpin;

a plurality of bushings;

a plurality of set screws;

a baseplate configured to be secured to the underside of said skateboard, said baseplate including a pivot recess and said baseplate configured to accept said kingpin;

a hanger including

an axle;

a pivot stem projecting from a mid portion of said hanger;

a ring-shaped member projecting from a mid portion of said hanger, said ring-shaped member defining an opening and said ring-shaped member including a plurality of bores substantially parallel to said axle;

wherein

said pivot stem rests in said pivot recess;

said ring-shaped member is sandwiched between said plurality of bushings;

said kingpin is routed through said opening defined by said ring-shaped member, said kingpin is adjacent to said plurality of bores of said ring-shaped member, and said kingpin is accepted by said baseplate; and

said plurality of bores of said ring-shaped member accept said plurality of set screws.

2. The skateboard truck assembly of claim 1 wherein the shaft of said kingpin includes a plurality of flat surfaces adjacent to said plurality of bores of said ring-shaped member.

3. A skateboard truck assembly comprising:

a kingpin;

a plurality of bushings;

a plurality of rigid elements;

a baseplate configured to be secured to the underside of said skateboard, said baseplate including a pivot recess and said baseplate configured to accept said kingpin;

a hanger including

an axle;

a pivot stem projecting from a mid portion of said hanger;

a ring-shaped member projecting from a mid portion of said hanger, said ring-shaped member defining an opening and said ring-shaped member including a plurality of bores substantially parallel to said axle;

wherein

said pivot stem rests in said pivot recess;

said ring-shaped member is sandwiched between said plurality of bushings;

said kingpin is routed through said opening defined by said ring-shaped member, said kingpin is adjacent to said plurality of bores of said ring-shaped member, and said kingpin is accepted by said baseplate; and

said plurality of bores of said ring-shaped member accept said plurality of rigid elements.

4. The skateboard truck assembly of claim 3 wherein the shaft of said kingpin includes a plurality of flat surfaces adjacent to said plurality of bores of said ring-shaped member.

5. A skateboard truck assembly comprising:

a kingpin;

a plurality of bushings;

a plurality of rigid elements;

a baseplate configured to be secured to the underside of said skateboard, said baseplate including a pivot recess and said baseplate configured to accept said kingpin;

a hanger including

an axle;

a pivot stem projecting from a mid portion of said hanger;

a ring-shaped member projecting from a mid portion of said hanger, said ring-shaped member defining an opening and said ring-shaped member including said plurality of rigid elements substantially parallel to said axle;

wherein

said pivot stem rests in said pivot recess;

said ring-shaped member is sandwiched between said plurality of bushings;

said kingpin is routed through said opening defined by said ring-shaped member, said kingpin is adjacent to said plurality of rigid elements, and said kingpin is accepted by said baseplate.

6. The skateboard truck assembly of claim 5 wherein the shaft of said kingpin includes a plurality of flat surfaces adjacent to said plurality of rigid elements.
