Provided is a running device including a frame (11) and a first wheel part (15) and a second wheel part (35) arranged with an appropriate distance therebetween along a running direction (R). The first wheel part (15) includes a first left support arm (17) and a first right support arm (26) arranged on the frame (11) in a manner to be swingable within a plane extending along the running direction (R). The second wheel part (35) includes a second support arm (36) arranged on the frame (11) in a manner to be swingable within a plane perpendicular to the running direction (R). The first left support arm (17) has first left wheels (19, 21) respectively on both sides thereof, and the first right support arm (26) has first right wheels (28, 30) respectively on both sides thereof. The second support arm (36) has a second left wheel (38) and a second right wheel (40) respectively on both sides thereof.

A frame, in particular of a universal carrier, which includes a chassis of the frame, a left axle with two portal suspensions at the ends of the left axle, a right axle with two portal suspensions at the ends of the right axle, and the double-sided stabilizing lever. The double-sided stabilizing lever is pivotally mounted on the chassis of the frame in the transverse direction. The axles are pivotally mounted on the chassis of the frame in the longitudinal direction. The double-sided stabilizing lever is connected to the left axle and the right axle and is arranged between them transversely.

The Lateral Trailer Suspension Support Device system is a suspension support that locks the axles of a trailer into the frame of the trailer, similar to a track bar on a truck. It is a lateral trailer suspension support device for reducing lateral loading of a trailer body having a wheeled axle comprising a frame rail connectively attached to said trailer body, a rigid member having a frame connection end having a first flexible joint connectively attached to said frame rail and an axle connection end having a second flexible joint connectively attached to said wheeled axle. It prevents and decreases lateral loading on all types of trailers. It can be used on single, tandem, and triple axle trailers.

A tandem wheel assembly for a work vehicle includes a tandem wheel housing, a center drive member rotatably disposed within the housing, first and second wheel end assemblies, a coupler between each wheel end drive member and the center drive member, and a brake assembly. Each wheel end assembly includes an input shaft, a wheel end drive member mounted thereon, a wheel end gear train coupled to the input shaft, an output shaft coupled to the wheel end gear train, and a wheel end hub coupled to the output shaft for supporting one of the wheels. The brake assembly is coupled to the tandem wheel housing and to the input shaft or the output shaft of at least one of the first wheel end assembly or the second wheel end assembly and reduces the amount of backlash.

Various systems and techniques for providing enhancements to bogie-equipped vehicles are described and discussed. Such systems and techniques include, for example, actively driven bogie differentials, elevated obstacle mounting techniques, worm-drive steering, parking modes using toe-in or toe-out wheel steering, speed-sensitive steering mode selection, and various other enhancements and techniques.

A pivotable wheel mount assembly may include a mounting bracket and a swing arm coupled to the mounting bracket. The swing arm may be movably coupled to the mounting bracket or the trailer and to a wheel and/or suspension so as to enable the wheel to be rotated from a downward or operational position to a horizontal or stowed position. The assembly may include an actuator support bracket coupled to the mounting bracket and an actuator that provides mechanical assistance moving the wheels between positions. One or more locking mechanisms may be provided to secure the assembly in either the operational position, the stowed position, or both.

An arrangement and method are provided for enabling rotation movement between a tandem or caterpillar axle and a body of a vehicle. This type of vehicle includes at least one body part that is provided with a tandem or caterpillar axle. At least one body part includes a main body and an auxiliary body connected to it to rotate around the longitudinal axis of the vehicle or an essentially parallel axis thereto. The tandem or caterpillar axle is connected substantially rigidly to the main body, and the body part has at least one actuator for controlling the rotation movement between the main body and auxiliary body. In this way, changes in the position and motion status of the auxiliary body, especially in relation to the rotation around the longitudinal axis of the vehicle, are arranged to cause in the actuator a pushing or pulling motion that steers the auxiliary body to a rotation movement for the purpose of arranging the auxiliary body to a substantially horizontal position.

A couplable automotive road vehicle includes two front wheels, a chassis having a front part and a rear part, an articulated connection device, and front and rear couplings. A wheel cylinder is defined as the cylindrical geometric shape surrounding the two front wheels when the wheels are not turned. The front part of the chassis includes a chassis beam disposed behind the front wheels, outside the wheel cylinder. The front coupling includes a yaw rigid coupling module mounted on the chassis beam between the two front wheels. The vehicle includes, for each front wheel, a suspension arm mounted on the chassis beam and extending around the wheel cylinder, above same, and a tie rod for controlling the steering device, located above the wheel cylinder.
