Abstract
A pair of upright arms are connected at their lower ends to an anchoring beam that lies on the floor after the truck is driven onto a ramp. The front truck axle is positioned below the top ends of the upright arms, which are then joined by a pressure distributor located above the axle to form an upright arm assembly. A hydraulic ram presses upwardly against the axle, which is restrained by the pressure distributors, thereby bending the axle to align the wheels. A system of countersunk apertures and mating conical frustrum fittings and bushings distribute the resulting forces more evenly throughout the apparatus, thereby preventing bending of the upright arms.
Claims20
A wheel alignment apparatus for bending front axles comprising:
- a. at least one upright arm assembly;
- b. an anchoring beam;
- c. means for connecting said upright arm assembly to said anchoring beam;
- and
- d. means for distributing forces through said upright arm assembly more evenly than a cylindrical fastening system.
A wheel alignment apparatus for bending front axles comprising:
- a. at least one upright arm assembly, said upright arm assembly further comprising a pair of upright arms, each said upright arm further comprising an inner face and an outer face and an upper end and a lower end, an anchoring beam aperture adjacent to said lower end and countersunk into said inner face and a plurality of spaced pressure distributor member mounting apertures adjacent to said upper end and countersunk into said inner face and a pressure distributor between said upright arms adjacent to said upper end of said upright arms, said pressure distributor further comprising a first conical frustrum portion and a second conical frustrum portion, each received in one said pressure distributor member mounting apertures in each of said two upright arms;
- and
- b. an anchoring beam having a plurality of spaced mounting apertures to which said upright arm is connected;
- and
- c. means for applying force to an axle, said force applying means being supported by said anchoring beam.
A wheel alignment apparatus for bending front axles comprising:
- a. at least one upright arm assembly, said upright arm assembly further comprising a pair of upright arms, each said upright arm further comprising an inner face and an outer face and an upper end and a lower end, an anchoring beam aperture adjacent to said lower end and countersunk into said inner face and a plurality of spaced pressure distributor member mounting apertures adjacent to said upper end and countersunk into said inner face;
- and a pressure distributor between said upright arms adjacent to said upper end of said upright arms, said pressure distributor further comprising a first conical frustrum portion and a second conical frustrum portion, each received in one said pressure distributor member mounting apertures in each of said two upright arms and each flanking a central cylindrical portion and a aperture through said pressure distributor along the longitudinal axis of said pressure distributor;
- b. an anchoring beam having a plurality of spaced mounting apertures to which each said upright arm is connected, each said mounting apertures having a countersunk opening on each of two opposed faces of said anchoring beam;
- c. a bushing between each said upright arm and said anchoring beam;
- and
- d. a hydraulic ram supported by a top surface of said anchoring beam.
