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 steering apparatus for an agricultural vehicle includes a vehicle axle suspended in an oscillating or resilient manner, steerable wheels located on the vehicle axle, and an actuating apparatus for influencing a steering angle which is adjustable on the steerable wheels. A device actively limits an oscillating angle or deflection path arising on the vehicle axle. Moreover, the device operably activates a control unit according to a full steering angle to be anticipated on the steerable wheels as a result of travel.

A suspension assembly for a vehicle may include a wheel support structure operably coupling a wheel to the suspension assembly, a bolt-in spring seat bracket operably coupled to the wheel support structure, and a spring supported by the bolt-in spring seat bracket and disposed between a chassis of the vehicle and the bolt-in spring bracket. The bolt-in spring seat bracket may be adjustable to change a ride height of the vehicle.

A system for suspending an automobile using an air rear suspension is provided. The system may include an automobile having a body, a front axle, and a rear axle; a linkage bar connected to said body and to said rear axle, wherein said connections allow for relative movement between said body and said rear axle; a cantilever bar having a first cantilever end and a second cantilever end; a damper; and an air spring, wherein said cantilever bar is connected to each of said rear axle and said body at said first cantilever end, wherein said cantilever bar is connected to each of said damper and said air spring at said second cantilever end, wherein said damper and said air spring are each connected to said body, and wherein said linkage bar and said cantilever bar are each configured to move in response to movement of said rear axle relative to said body.

The present invention relates to a novel robot drive train that is robust, and low cost. The drive train is capable of ascending obstacles greater than the height of its wheels, protects the robot against shocks/vibration, and is highly maneuverable, such as able to execute a zero-point turn. To control the bogie in a variety of scenarios, a novel mechanism is used to selectively limit the articulation range of the bogie and/or programmatically apply a preload to the bogie axle.

A vehicle includes a platform, a first axle beam attached to a front end of the platform at a first pivot, and a second axle beam attached to a rear end of the platform at a second pivot. The first axle beam is rotatable independently of the platform. The second axle beam is rotatable independently of the platform. The vehicle includes a plurality of first wheels fixed to the first axle beam and configured to move the platform. The vehicle includes a plurality of second wheels fixed to the second axle beam and configured to move the platform. The vehicle includes a link attached to one side of the platform at a third pivot. The link is movable about the third pivot independently of the beams to constrain movement of the platform in response to articulation of the first axle beam and/or the second axle beam.

Disclosed are various embodiments, aspects and features an oscillating track system that includes an oscillating track lock subsystem. The oscillating track system may include a track operable to rotate around a housing structure that is configured to receive an axle. While in operation, i.e. while the track is being rotated around the housing, the oscillating track system may be able to oscillate about the axle and, in doing so, incline or decline to accommodate undulating terrain. Advantageously, when stopped, the degree to which the oscillating track system has oscillated around the axle may be locked in place via an oscillating track lock subsystem comprised within the oscillating track system, thereby providing stability to the heavy equipment that includes the oscillating track system.

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.

Disclosed are an adaptive chassis and a robot. The chassis includes: a support (110), a first wheel (101) and a second wheel (102) arranged at two sides of a first end of the support (110), a first suspension seat (120) arranged at a bottom side of a second end of the support (110), a first rotating shaft (121) arranged on the first suspension seat (120), a first crossbeam (130) connected with the first rotating shaft (121) and being capable of rotating around the first rotating shaft (121), and a third wheel (103) and a fourth wheel (104) arranged on two ends of the first crossbeam (130). An axis of the first rotating shaft (121) is consistent with a moving direction of the chassis. When a state of a supporting surface changes and one of the third wheel (103) and the fourth wheel (104) gets out of contact with the supporting surface, the out-of-contact one of the third wheel (103) and the fourth wheel (104) can rotate around the first rotating shaft (121) by means of the first crossbeam (130) to make contact with the supporting surface.
