摘要:
An intermodal chassis for highway transportation of 53 foot shipping containers having a rear axle positioned under the chassis frame so that the kingpin-to-rear-axle length is no more than 40 feet, and a forward axle positioned under the frame between the gooseneck and the rear axle so that a forward-to-rear-axle length is at least 12 feet. The chassis includes air bag suspension that automatically deflate the air bags when the brakes are locked, preventing damage when loading a container onto the chassis. Other features include self-scaling and load-leveling, and other weight savings include use of smaller sized aluminum wheels.

A load bearing carrier system for carrying additional cargo in the vehicle or on the carrier itself. The support system increases the wheelbase of the vehicle to stabilize the added weight and extended weight out the back of the vehicle at high speeds. The load bearing structure attaches to the tow vehicle at trailer hitches or directly to the frame of the vehicle. The system includes a receiver hitch or a multiple receiver hitch beam attached across the rear of the tow vehicle attached to the tow vehicle frame. The carrier mounting beam has trailer tongues pinned into said receivers and the attached mounting beam of the carrier has vertical beams near each end to mount the springs, air bags, air shocks, load bearing air cylinders or spring enhanced shocks type of suspension, the cargo platform and attached trailer hitch. The mounting beam has pivot beams to mount the spindles, hubs, brakes, wheels and tires. The suspension forces the pivot beams, spindles or axles, hubs, wheels, and tires to the ground lifting the carrier, cargo, cargo deck, truck, and trailer hitch attached to the cargo deck upward in a load bearing manner.

A suspension system can include an air spring, an air reservoir external to the air spring, and a flow control device which variably restricts flow of air between the air spring and the air reservoir. Flow between the air spring and the air reservoir may be permitted in response to compliance of the suspension system, and the air spring can have an internal air volume at least 2½ times as great as a volume of the air reservoir. The flow control device may permit flow between the air spring and the air reservoir in response to a predetermined pressure differential level across the flow control device. Multiple air reservoirs can be internal to an axle, and can be isolated from each other in the axle.

A vehicle suspension assembly includes first and second mounting brackets each adapted to couple to a vehicle frame assembly, first and second trailing arms each having a first end pivotably coupled to the mounting brackets, and a second end located outboard of the first end of the associated trailing arm; an axle member having a first end and a second end; an integrated first mounting arrangement and an integrated second mounting arrangement coupled to the associated ends of the axle member, wherein the mounting arrangements pivotably couple the second end of the associated trailing arm to one of the ends of the axle member, and wherein the mounting arrangements couple one of the ends of the axle member to the spindle assembly.

A vehicle suspension assembly includes an axle member movable between a first position and a second position, mounting brackets adapted to couple to a vehicle frame assembly, trailing arms pivotably coupled to mounting brackets and pivotably coupled to the axle member, a lift arrangement including a pair of diaphragm chambers each having a push plate and a flexible bladder, the push plate of the diaphragm chamber dividing the associated diaphragm chamber into a first compartment and a second compartment, the first compartment of each diaphragm chamber being adjustably pressurized to move the push plate of the associated diaphragm chamber, and at least one push rod defining a single longitudinal axis and connected to each push plate such that pressurization of the diaphragm chambers cause a translational movement of the at least one push rod, thereby causing the axle member to move between the first and second positions.
摘要:
A trailer for a trailer truck, comprising a chassis provided with a central chassis element and at least one axle with independent wheel suspension, which is connected to the chassis, the wheel suspension comprising a first, lower wheel suspension arm that is pivotally connected to the chassis about a first pivot axis that extends substantially in the longitudinal direction of the chassis, a second, higher wheel suspension arm that is pivotally connected to the chassis about a second pivot axis, a steering knuckle connecting the first wheel suspension arm and the second wheel suspension arm, a wheel axle attached to the steering knuckle, on which a wheel is rotatably mounted. The second pivot axis extends substantially in the transverse direction of the chassis, with the second end of the second wheel suspension being spaced from the first end of the second wheel suspension arm, seen in the longitudinal direction of the chassis.
摘要:
A tire management system for a truck or trailer comprising an axle having a first tire mounted thereto, the system comprising an air pressure supply connected to the tire so as to allow sealed communication of pressurized air between the air pressure supply and the first tire, and a first pilot-operated check valve in sealed fluid communication with the air pressure supply and with the first tire, the first pilot-operated check valve being configured to allow air to flow only from the air pressure supply to the first tire when a pilot of the first pilot check valve is not activated, and to allow air to flow between the first tire and the air pressure supply when the pilot of the first pilot-operated check valve is activated.
摘要:
For adjusting the supporting load of a central axle trailer equipped with at least two axles having pneumatic suspensions and a pneumatic suspension system that includes separate pneumatic suspension circuits on the axles with pneumatic suspensions, a method and electronic control device are provided by which the respective quantities of air are separately adjustable. When the current supporting load exceeds a permitted supporting load range, the current supporting load is reduced by separate alteration of the quantity of air in at least one of the pneumatic suspension circuits; and, when the current supporting load is below the permitted supporting load range, the current supporting load is increased by separate alteration of the quantity of air in at least one of the pneumatic suspension circuits.

A suspension system includes a frame mount assembly, a swing arm assembly and an air spring. The trailer includes a rail with top and bottom rail surfaces. The swing arm assembly is pivotally mounted to a pivot about a swing arm pivot axis located above the bottom rail surface when the suspension assembly is mounted to the trailer.
