ABSTRACT:
A vehicle axle straightening system for straightening a bent and twisted vehicle axle includes members engaging the axle to hold certain portions while forces are applied to the axle at portions spaced therefrom to bend and twist the axle to return same to its original orientation, the system particularly includes a pair of axle engaging assemblies each extending between and having opposite end portions thereof attached to respective anchors mounted in a floor and each assembly having a top member engageable with an upper surface of the vehicle axle thereby resisting upward movement of the respective engaged portion of the vehicle axle in response to an upwardly directed force by a force applying device extending between the floor and a selected portion of the vehicle axle and spaced from the axle engaging assemblies. The floor anchor for heavy truck axles has anchor sleeves or pots spaced along and secured to structural members which are in spaced parallel opposed relation and plates or webs connecting the opposed sleeves all set in a thick concrete floor. The vehicle axle straightening system includes an elongated bar positioned substantially normal to the vehicle axle and having a wrench portion at one end thereof engageable with the vehicle axle and adapted to twist same in response to a force applied to another end of the elongated member while the connections to the anchors hold down the axle. The vehicle axle straightening system includes a lever member having one end portion engageable with the upper surface of the vehicle axle and adapted to apply a downwardly directed force thereto in response to an upwardly directed force applied to another end portion of the lever member for moving same about a fulcrum in engagement with a lower surface of the vehicle axle.
