  • Patent number: 10449817
    Abstract: A slider suspension system for a heavy-duty vehicle includes a slider assembly with a main member that is movable relative to a primary frame of the heavy-duty vehicle in a first direction along the extent of the main member. The main member has a first portion and a second portion extending transverse to the first portion. A friction reducing slider wear pad is fixed to the main member and interposed between the main member and the primary frame. The friction reducing slider wear pad has a first segment fixed to the first portion of the main member. The friction reducing slider wear pad also has a second segment engaging at least a part of the second portion of the main member to inhibit movement of the friction reducing pad relative to the main member in a second direction transverse to the first direction.

  • Patent number: 10370033
    Abstract: Improvements to a sliding sub-frame for heavy-duty vehicle suspensions include torque boxes, an air slider-pin system, and a heavy-duty shear-off nut. In the prior art, all four sliding pins are linked together with bars so if one sliding pin is stuck they are all stuck. Here, each sliding pin has a dedicated air assist bladder and is independent and can release on its own. That way, if one sliding pin is stuck, it is a much easier job to get it unstuck by moving the vehicle. The torque box relates to stress-relief measures of shear strains at critical fastened (eg., bolted) connections. The shear-off nut has a break-neck flanked between a hex head and collet nut. The clearance between the outside sidewall of the collet nut very nearly fully spans the space between the flats of a hex socket for the hex head, thereby providing light on-axis support.

    Abstract: A trailer including an axle assembly which travels horizontally beneath the trailer, transforming the trailer from a transport position to a loading position. The axle assembly is connected to a tail rod which connects with a tail ramp located at the rear of the trailer. As the axle assembly travels forward, the tail rod is removed from the tail ramp, causing the ramp to tilt down towards the ground away from the trailer bed, allowing a vehicle to be driven up over the ramp and onto the bed of the trailer. A hitch assembly allows the hitch to move in relation to the trailer, preventing damage to a towing vehicle.

  • Patent number: 9272599
    Abstract: A weight distribution system for dynamically controlling and adjusting the weight load on each axle of a vehicle uses a manifold that is fluid flow disposed between a source of pressured air of the vehicle and the air bags of the vehicle. The manifold allows an individual air bag to be inflated or deflated to a desired pressurization depending on either preprogrammed or user input parameters. By individually controlling the air bags, the system allows the setting of the maximum amount of weight to be borne by a given axle so that tires can be removed from that axle without weight overloading the remaining tires. The system also automatically self-levels the chassis of the vehicle and maintains proper ride height of the vehicle using input from a height sensor located on one of the axles.

    Abstract: A self initiated prone progressive crawler facilitates crawling in infants by sensing the infant's intent and assisting movement. The device is designed as a mobility aid to assist an infant in prone locomotion. The infant can be placed in a prone position on a platform and secured with hook and loop straps. The arms and legs are unconstrained and are able to reach the floor comfortably. The self initiated prone progressive crawler is a motorized wheeled platform which has three points of contact with the ground. One point is an industrial trackball, mounted upside down to provide positional and positional derivative data to a controller. It is located roughly under the chest of the infant and is highly sensitive to movement. The other points of contact are two DC torque motors which are controlled by the controller.

    Abstract: In exemplary implementations of this invention, a foldable vehicle has a foldable chassis. The wheelbase (and thus the overall footprint) of the vehicle can be reduced when parking, and can be extended when driving on the open road. In exemplary implementations the ability to shorten and lengthen the wheelbase is achieved by using two 4-bar linkages, activated by one or more linear actuators positioned in parallel. The dual 4-bar linkage and linear actuator(s) can provide: (i) the ability to maintain full maneuverability in the vehicle's folded and unfolded state; (ii) a fail-safe static system, and (iii) a rigid but transformable chassis.

    Abstract: A locking pin mechanism for a transport semi-trailer, the locking pin mechanism is used for locking longitudinally extending members of a frame of a transport semi-trailer together with a trailer body movably arranged on the longitudinally extending members. The locking pin mechanism comprises at least two bolt assemblies and a linkage assembly for driving the at least two bolt assemblies. The bolt assembly comprises a bolt, an inner spring, a sliding sleeve, an outer spring and a bracket. The sliding sleeve at an end away from its sliding sleeve end-plate is connected with the linkage assembly; the linkage assembly can be pulled such that the sliding sleeve of the bolt assembly is compresses the inner and outer springs to force the bolt to be pulled out from a locating hole under an action of an elastic force of the inner spring; and after the linkage assembly is released, the bolt can be inserted into the locating hole under the action of the elastic force of the outer spring.

  • Patent number: 8152200
    Abstract: Heavy equipment trailer and deck extension. The trailer has an elongated main deck with longitudinally extending frame members on opposite sides thereof, and ground engaging wheels toward the rear of the main deck. The extension has longitudinally extending frame members aligned with the frame members of the main deck, and coupling pins extend between the frame members of the main deck and the extension in load supporting relationship, with lock pins preventing longitudinal separation of the main deck and the extension. C-shaped channel members extend along the upper, lower, and outer sides of the extension, past the coupling pins, and along upper, lower, and outer side portions of the frame members of the main deck to hold the frame members in alignment and prevent sagging under load conditions.

  • Patent number: 8028784
    Abstract: A trailer is provided with a bed and a slidably adjustable axle assembly. The bed includes a frame with left and right, inverted U-shaped channels. The axle assembly includes left and right rails upon which the channels are slidably mounted. Pins extend through the channels, but not through the rails, to limit sliding movement of the bed relative to the axle assembly. The pins are inserted into the channels with a twist lock action under spring bias. Lock members are provided to prevent accidental removal of a pin from the channel during travel.

  • Patent number: 7819619
    Abstract: A retractable ramp system mounts a slideable ramp between lateral rail members which extend the length of a truck chassis and a container mounted thereon. The ramp is slideably suspended from a guide rail running parallel to the lateral rail members by means of a carriage component, itself slideably mounted within the guide rail. It is readily and easily extended and retracted by one person. When positioned directly on a truck chassis, the rail system is located above the hydraulic, electrical, and other mechanical systems positioned within the well of the truck chassis, such that the ramp is slideably moveable over these system components without interfering with them or any other part of the truck chassis. The ramp system is conveniently used for loading and off-loading containers which rest on the truck chassis or which are elevated above the chassis.

  • Patent number: RE43943
    Abstract: A variable wheel base vehicle includes a vehicle body having front end rear ends supporting body members one of which is capable of displacement relative to the other. Drive motors mounted to the vehicle body are linked to the body members. A carriage assembly including drive wheels provide support for the vehicle body. An extension assembly responsive to the drive motor is connected to at least one of the body members. Upon actuation of the drive motor, the extension assembly enables one body member to displace relative to the other body member to enable extension and retraction of the vehicle wheel base. Each body member includes at least one wheel of the carriage assembly and, as a result of displacement of one body member relative to the other body member, the displaced body member provides increased counterbalance in the vehicle.
