  • Patent number: 10828935
    Abstract: A tractor or trailer axle replacement spindle and seal ring assembly includes a spindle with an elongate cylindrical body having bearing surfaces and threads. The seal ring is a shorter annular component having a circular opening sized to achieve an interference fit with the spindle. A portion of the exterior surface of the spindle and the interior surface of the ring seal includes complementary regions having a small, constant and equal taper. Preferably, at each end of the tapered regions of the spindle and the seal ring resides an annulus or cylindrical region of constant diameter. The spindle may also include a shoulder or flange at or adjacent its end opposite the threads which positively axially locates the seal ring thereon. When the two components are to be assembled, the seal ring is heated to several hundred degrees Fahrenheit and slid onto the spindle until the complementary tapered regions align.

  • Patent number: 10821776
    Abstract: An arrangement of wheels for a bi-directional vehicle may decrease the drag coefficient for the vehicle regardless of a direction of travel of the vehicle. A pair of wheels, each wheel of the pair having a configuration of fins to promote a desired aerodynamic effect, when located at a leading end of the vehicle promotes airflow laterally outboard of the vehicle body. In contrast, the same pair of wheels, when located at a trailing end of the vehicle promotes airflow laterally inboard of the vehicle body.

  • Patent number: 10814670
    Abstract: A low-speed vehicle wheel assembly includes a rim, at least three spokes, connectors, a central bearing seat, and bearings. Outer ends of the spokes are fixedly connected to an inner side wall of the rim through the connectors, respectively. Inner ends of the spokes are fixedly connected to an outer wall of the central bearing seat. The bearings are fitted in bearing holes of the central bearing seat, respectively. Because the rim and the central bearing seat are independent components, each component can be made with an independent mold and assembled according to the diameter of the wheel. The cost of the mold is lower, and the components are more versatile.

  • Patent number: 10814671
    Abstract: A tensile element connection, comprising first and second bracing elements and a tensile element having a first portion connected to the first bracing element and a second portion opposed to the first portion and connected to the second bracing element, and an applied tensile load along the tensile element. The tensile element includes a preformed rod that is comprised of reinforcement fibers in a matrix. At a temporarily elevated temperature greater than the service temperature, a localized region of the matrix is in a softened state of increased deformability such that a localized region of the rod is deformed under pressure to include a laterally outwardly projecting engagement surface. The tensile element is comprised of said rod with the engagement surface formed therein and is connected to one of the first and second bracing elements by means of an overlie engagement at the engagement surface to restrain the tension load.

  • Patent number: 10787211
    Abstract: Provided is a crawler pad with improved durability for preventing foreign materials from coming through between crawler pads, greatly improving the strength of steel cores and improving the integrity of a pad body and a steel core. In the prior one, the typical crawler pad had a problem that its life time keeps shortened because foreign materials such as sands, etc. penetrate through into the space between neighboring crawler pads, and the rubber-made pad body was damaged. Foreign material prevention stops are formed on with protruded from the front and back surfaces of the ground contact part, and function to firstly prevent foreign material from coming into space between two neighboring pad bodies, and overlap inclines are formed on the front and the back lower surfaces of the pad body respectively with inclined downwards so as to be overlapped with those of neighboring another pad body and thereby to form an overlap region and secondly prevent foreign material from coming into.
