A vehicle system includes a controller. The controller is configured to be communicably coupled to a plurality of actuators of a vehicle that facilitate repositioning a plurality of tractive elements coupled to a chassis of the vehicle. The controller is configured to (i) control the plurality of actuators to selectively reposition each of the plurality of tractive elements through a range of motion to attempt to maintain the chassis level and (ii) drive each of the plurality of actuators toward a mid-stroke position while continuing to attempt to maintain the chassis level and while the vehicle is moving.

A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

A method and apparatus for lowering the height of a wheeled vehicle for cargo height constraints during transportation. The rear leaf spring shackle on each side of the vehicle is connected to a sliding frame mount. In the transport configuration, fasteners are removed from the sliding frame mount, and the mount slides forward, rotating the rear leaf spring shackle from a near vertical to a near horizontal position, effectively lowering the height of the vehicle. To return the vehicle to the ride configuration, a screw jack member is attached to the sliding frame mount and a rear attachment point on the vehicle, pulling the sliding frame mount back, aligning attachment points of the mount with the frame member in the original position. The fasteners are reinstalled to lock the sliding frame mount into the ride configuration.

An axle load monitoring system is disclosed for a load-transporting motor vehicle having two or more primary axles and one or more auxiliary axles wherein the monitoring system detects a noncompliant axle carrying weight condition when the weight of the vehicle acting on any primary axle exceeds a prescribed maximum allowable axle carrying weight assigned to that axle and also when the weight acting on any group of the axles arranged consecutively exceeds a prescribed maximum allowable axle group carrying weight assigned to that axle group. And on such detection, the monitoring system recommends auxiliary axle usage that would result in no maximum allowable axle carrying weight and maximum allowable axle group carrying weight being exceeded provided the current gross vehicle weight does not exceed a prescribed maximum allowable gross vehicle weight determined by all of the axles and the current center of gravity of the vehicle is located within a certain compliance-manageable range. And with the monitoring system also recommending optimal auxiliary axle usage in other situations where full compliance may not be possible for various reasons.

An auxiliary axle suspension system for a motor vehicle is disclosed wherein a pair of hydraulically operated actuators position and force the auxiliary axle to help support the vehicle. And gas springs are provided that allow the actuators to extend and retract over a wide range of hydraulic operating pressure and thereby allow the auxiliary axle to adjust to a wide range of road grade differences between the auxiliary axle wheels and the wheels of the axles that normally support the vehicle without incurring significant gas and hydraulic pressure fluctuation and while isolating shock forces on the auxiliary axle wheels from the vehicle.

A suspension restraint system for an All Terrain Vehicle (ATV) includes a clamp fixed to at least one control arm of a suspension system, the clamp including a post, a rod mount fixed to a frame member, a rod configured to be secured to the rod mount, the rod including a hook, the hook being configured to engage the post of the clamp. The rod is configured to engage said clamp and restrain a movement of the suspension system when the suspension system is in a lowered position relative to the frame member.
摘要:
Generally described, aspects of the disclosed subject matter are directed to managing the configuration of a vehicle. In accordance with one embodiment, a method of modifying the configuration of a vehicle based on the vehicle's location is provided. The method includes receiving, from a remote Satellite Positioning System (“SPS”) device, positioning data that identifies the location of the vehicle. Then, the positioning data is used to identify one or more regulations that are applicable, given the location of the vehicle. Based on collected vehicle readings, a determination is made regarding whether the configuration of the vehicle should be modified. In turn, the method may cause the configuration of the vehicle to be modified to comply with the one or more regulations.

Described herein is a hydraulic suspension system mounted on a vehicle, including a plurality of hydraulic suspension units having a section of the vehicle corresponding thereto, and a hydraulic power means in communication with the plurality of hydraulic suspension units for providing a hydraulic fluid under pressure to actuate the plurality of hydraulic suspension units. The hydraulic suspension system mounted on a vehicle further includes a plurality of hydraulic valve assemblies associated with each of the plurality of hydraulic suspension units, wherein the plurality of hydraulic valve assemblies are in fluid communication between the plurality of hydraulic suspension units and the hydraulic power means, and a control means for controlling each of the hydraulic valve assemblies associated with each of the plurality of hydraulic suspension units.
摘要:
A surface vehicle capable of overcoming obstacles is disclosed in which the vehicle accelerates vertically while having a horizontal velocity. The vehicle has a frame and at least three wheels attached to the frame to which a horizontal propulsion system is coupled. Further, a vertical propulsion system is coupled to the frame and the wheels. The vertical propulsion system is capable of providing a force to such wheels normal to the surface so that the vehicle separates from the surface. The vehicle has an electronic control unit coupled to the vertical propulsion system to automatically control its operation.
