Abstract
An axle cartridge member receives a pair of torsion stub axles at opposite lateral sides thereof. The torsion stub axles include elongated axle housings, which are sandwiched between two parallel plates to align the torsion stub axles with respect to one another. The cartridge member includes a central arch extending between the two torsion stub axles, which can provide additional ground clearance when the axle cartridge member is mounted to a trailer.
Claims20
An axle cartridge member for a receiving a pair of torsion stub axles therein, the axle cartridge member comprising:
- a pair of laterally opposed bases, each base defining a cavity therein for receiving an elongated stub housing of the torsion stub axles;
- a pair of axle mounts, each axle mount coupled to a respective base of the pair of laterally opposed bases and including a lateral opening extending into the cavity defined in the respective base;
- an arch extending between the bases, the arch including a crossbar extending at a height above the bases, wherein the arch includes a portion that extends upward from each of the bases at an angle and meets the crossbar that extends generally horizontally between the portions of the arch;
- and
- at least one trailer mount arranged for coupling the trailer axle cartridge member to a trailer frame.
An axle cartridge assembly, comprising:
- an axle cartridge member including a pair of laterally opposed bases and an arch extending in a lateral direction between the bases, the arch including a crossbar extending at a height above the bases and oriented at an angle relative to the bases;
- a pair of torsion stub axles, each torsion stub axle including an elongated stub housing extending into a cavity defined in a respective base of the pair of laterally opposed bases;
- and
- a plurality of mounting fasteners coupling the pair of torsion stub axles to the axle cartridge member.
A trailer assembly, comprising:
- a trailer frame;
- an axle cartridge member including a pair of laterally opposed bases and an arch extending in a lateral direction between the bases, the arch extending at an angle relative to each base and including a crossbar extending at a height above the bases;
- a pair of torsion stub axles, each torsion stub axle including an elongated stub housing extending into a cavity defined in a respective base of the pair of laterally opposed bases;
- a pair of wheel assemblies, each wheel assembly including a wheel coupled to a respective one of the torsion stub axles;
- and
- a plurality of mounting fasteners coupling the pair of torsion stub axles to the axle cartridge member and coupling the axle cartridge member to the trailer frame.
