An electrical passenger car, the car including: an electrically driven motor; and wheels, where the wheels include a first wheel, a second wheel, a third wheel, and a fourth wheel, where the first wheel and the second wheel have a radius 20 percent larger than the third wheel and the fourth wheel, where the electrical passenger car includes a total weight, where the electrical passenger car includes a center of gravity designed so that greater than 50% of said total weight will be over the first wheel and the second wheel, and where the electrical passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a passenger car having wheels of a smaller radius.

A bogie axle system having a slew bearing assembly that pivotally couples a chain housing to an axle housing. The slew bearing assembly includes a plurality of bearing elements that are received in a bearing groove of a spindle and that are disposed between the spindle and an outer race.

An improvement in a Two Way Automated Communications System (TWACS) requires only three of six previously required vectors to communicate with remote communication equipment (RCE) devices installed in the three phases of a utility's low voltage distribution network for concurrent outbound signal communications over the TWACS. The reduction in vectors allows an outbound injection silicon-controlled rectifier (SCR) array used for such purposes to be greatly simplified and further allows the SCRs in the array to be operated independently, and therefore concurrently.

A suspension for a two-wheeled vehicle includes first and second fork legs. Each fork leg includes a dropout. Each dropout has an opening therethrough. At least a portion of one of the openings is threaded. Each of the dropouts includes a split-damp pinch bearing defining the opening and operable between an open position and a locked position, and a hand operable actuator pivoted to the bearing for operation thereof. The suspension further includes a one-piece axle. The axle is disposed through the openings. The axle has a threaded first end engaged with the threaded portion. The axle has an ergonomic grip formed at a second end. The bearing tightly engages an outer surface of the axle in the locked position, thereby rotationally coupling the axle to the dropout.

The present application includes a system and method for transporting a car seat outside of a vehicle. The system includes a wheel assembly configured to couple to a portion of the car seat. The wheel assembly attaches to existing base attachment portions on the car seat to minimize any need for retrofit operations. The system further includes a mobility handle configured to adjust in length and couple to a portion of the car seat. The mobility handle is designed to allow an individual to guide and control the movement of the car seat on the wheel assembly.

A powertrain includes an axle end assembly rotatable about a wheel axis. A wheel bearing housing rotatably supports an outer axle end of the axle end assembly. A wheel hub is rotatably supported by the wheel bearing housing for rotation about the wheel axis. A hub actuating system is coupled to the wheel bearing housing, and is selectively controllable between an engaged state for rotatably coupling the wheel hub and the outer axle end together, and a disengaged state for de-coupling the wheel hub and the outer axle end. At least one axle bearing interconnects and rotatably supports the outer axle end relative to the actuator housing so that the outer axle end and the wheel hub are axially stacked relative to each other along the wheel axis, and the wheel hub and the outer axle end do not radially overlap each other relative to the wheel axis.

A traveling toy wheel whose simple configuration allows multiple devices to be enjoyed and can further change fine offsets is provided. The traveling toy wheel includes a first rim member to which a tire is mounted and a second rim member which includes a fitting portion into which a wheel hub of a traveling toy is fitted. Fitting holes as fixing portions are provided in one of the first rim member or the second rim member and elastic convex pieces as fixed portions are provided in the other of the first and second rim members. When the elastic convex pieces are fitted in the fitting holes, the first rim member and the second rim member are jointed relatively unmovably. A plurality of fitting holes are arranged at different positions, so that it is possible to easily adjust an offset of the wheel.
