A locking system including a lock washer, a nut, and a retainer which together act to secure a wheel hub to a spindle. The lock washer has a tab which extends through the nut and the retainer, and which wraps around and back over the retainer in order to axially and rotationally secure the retainer. The tab has an initial position that corresponds to an unlocked position and a distal end of the tab extends beyond the hub in the initial position far enough to prevent an end cap from being placed over the tab when the tab is in the initial position. As such, installation of the end cap is not possible until the tab is bent into a locked condition.

A semi-trailer wheel restraint system having at least one bearing or swivel, or a combination of bearing(s) and swivel(s), and one or more cable sections and one or more hub cab attachments for receipt into one or more wheel assemblies and through a hollow core of the trailer's axle. During a wheel bearing failure, the wheel restraint system keeps the loose wheel assembly near the end of the axle by anchoring it to the opposite-end's hub cap, thereby preventing a run-away wheel assembly and providing an operator of the truck an opportunity to safely stop the rig.

A driving wheel comprises an axle, a wheel body, and a driving assembly. The wheel body is of a hollow structure and is rotatably arranged on the axle. The driving assembly comprises a shell, a motor, and a transmission mechanism. The shell is fixedly arranged on the axle and located in the wheel body, and the motor is fixedly arranged in the shell and connected to the wheel body by the transmission mechanism. An output shaft of the motor is arranged perpendicular to the axle, which can reduce the space occupied by the motor and improve space utilization.

A running gear assembly for a vehicle includes an inner flange, an optional brake member assembly, and a unit hub. The inner flange may be connected to either an axle or an independent suspension member. The brake member assemblywhen presentmay be any type of brake member assembly commonly used for vehicles, includingbut not limited toelectrically, hydraulically, or mechanically actuated drum brakes and hydraulically actuated disc brakes. The unit hub allows the wheel and tire assembly to connect to the vehicle without the need for a spindle.

The present disclosure provides a composite powered wheel set, a train, a wheel-rail system and a train control method. The composite powered wheel set comprises two booster wheels and two support wheels mounted on a driving axle. The booster wheels are fixedly mounted on two ends of the driving axle, the support wheels are mounted on the driving axle via bearings, the moving axle is connected to a first transmission device, which is connected to a first power mechanism, and the driving axle is further connected to a train bogie via a connecting device. Booster wheels and booster rails are provided to improve anti-skid performance, so the train will not skid when running on a steep slope or under a heavy traction load. Restrictions on the railway slope, train traction load, and train speed are eliminated to a great extent, and the application scope of the wheel rails is expanded.
