A front tow extended saddle configured for mounting a vehicle to a towing vehicle and a method of towing a vehicle using the front tow extended saddle are provided. The front tow extended saddle includes front, middle, and rear portions, with the front and rear portions extending along different planes. A protective cover extends along the front tow extended saddle and is supported above the wheels of the towing vehicle.

Example apparatuses and techniques are disclosed for towing tracked vehicles at high speeds without various deficiencies and for allowing a vehicle to be configured to extend supplemental wheels from a storage configuration into a ground support configuration in which the vehicle is able to make use of the supplemental wheels for additional ground support.

A trailer coupler system can include one or more skid plates made from extruded aluminum, one or more support tubes attached to the skid plates, a plurality of struts having a first end attached to the one or more skid plates, a ball housing attached to a second end of at least two of the plurality of struts, a first towball positioned within the ball housing, an adapter sleeve attached to the ball housing, a support plate extending from a support tube or skid plate to the adapter sleeve, an adapter having a kingpin coupler for coupling to a kingpin of a trailer, and a towball coupler for directly coupling with the first towball.

An apparatus and system for: combining independent driving vehicles into a single assembly for condensed, efficient, variable capacity transportation on common routes; and for separating into independent vehicles for flexibility on diverse routes. Connection logistics are exchanged locally via line of sight optical channel. Retractable coupling and mated coupling on opposing ends of the vehicles provide multiple degrees of freedom (DOF) to accommodate misalignment during initial dynamic engagement, and lock as rigidly coupled assembly with zero DOF. Mating vehicles' doors open during transit, permitting inter-vehicle movement and consolidation of passengers en route to urban locales, and release of empty vehicles. On return, independent vehicles combine to dense passenger vehicles from urban locales for redistribution of passengers in individual vehicles that later separate for diverse destinations. Slaved vehicle systems allow one vehicle to control coupled vehicles' systems of retractable suspension, coordinated steering, power sharing. Utility vehicles couple to assembly for service.

The recreational vehicle trailer chassis includes two main frame rails running front to back with a series of perpendicular connecting main cross-members to form a structural configuration increasing the torsional rigidity of the frame. The main floor and support framing has a front and rear living area generally divided by the direction of structural trusses. Above the rear and middle main frame rails is the rear and middle floor framing formed with a plurality of frame members. Between the rear and middle main frame rails and below the rear and middle main floor support framing are structural web beam trusses perpendicular to the main frame rails along with vertical support columns that connect the lower main frame to the rear and middle living area floor framing further increasing structural torsional rigidity. Above the forward main frame rails and vertical support columns is the front floor framing with a plurality of frame members along with structural web beam trusses running parallel with the forward living area floor. Outward from the main frame rails and vertical floor support columns is the front to back side saddle framing to allow access to the basement area internally and externally. The furthermost forward floor framing sections are where the hitch structure and hitch are located.

A trailer system for providing transportability for a cavity cleaning and coating system may include a frame, a bed that is attached to the frame, a pair of ground engaging elements that are attached to the frame, and a lifting and reclining assembly that is attached to the frame that is configured to raise and lower the cavity cleaning system into position over a cavity.

An automatic guided vehicles (AGV) can include: motors, wheels, motor controllers, and batteries coupled to an elongated frame. The two wheels can be mounted on opposite sides of the elongated frame. The wheels can be coupled to motors which can be controlled by motor controllers. The motors and motor controllers can be attached to the frame and a connector flange can be mounted on a center portion of the AGV frame. Linkages are used to couple a plurality of AGVs together. In a two AGV embodiment, the AGVs can be mounted to a front portion and a rear portion on a centerline of a platform. In a four AGV embodiment, front width, rear width, left length, and right length linkages can form a parallelogram with AGVs couple to each of the four corners of the parallelogram.

Methods and apparatus are disclosed for a load-sensing hitch utilizing a system of strain gauges. An example apparatus includes a hitch including a first support including a first end, a second end, and a mid-portion located between the first end and the second end, the mid-portion having a cross-sectional area smaller than the cross-sectional area of the first end or the cross-sectional area of the second end, a strain gauge located at the mid-portion of the first support, a frame attachment to couple the hitch to a frame of a vehicle, the support coupled to the frame attachment, and a load manager to determine a load condition based on sensor data from the strain gauge.

A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.

A tow bar assembly for mounting to a vehicle, the tow bar assembly including a main beam configured to support a hitch receiver, the main beam comprising a bracket engaging portion at or near each end, a pair of brackets configured to securely mount to the vehicle, each bracket including a beam engaging portion, and a pair of fastening means for securing respective brackets at or near respective ends of the main beam, wherein each bracket and its respective beam bar engaging portion is configured to cooperatively interengage with a respective bracket engaging portion so as to locate and orient the bracket with respect to the main beam.
