A storage arrangement for lines from a tractor truck to a trailer including at least one of an electrical line, a first pneumatic line and a second pneumatic line includes a housing member configured to be secured to the truck, a first receiver connected to the housing and configured to couple to a select one of the electrical and pneumatic lines and a control arrangement operably coupled to the first receiver such that upon coupling of the select one of the lines with the first receiver the control arrangement allows an operator to unlock a kingpin from a fifth wheel hitch plate assembly, wherein the control arrangement prevents the operator from unlocking the kingpin from the fifth wheel hitch plate assembly prior to the select one of the lines being coupled with the first receiver.

Vehicle coupling lines storage and control arrangement

A kingpin assembly includes a housing having a recess located therein, a kingpin having at least a portion located within the recess of the housing, wherein the kingpin is secured within the recess of the housing, and wherein the kingpin includes an axis extending along a length of the kingpin, and a sensor arrangement configured to sense a force exerted on the kingpin in a first direction that is substantially perpendicular to the longitudinal axis, and a second direction that is substantially perpendicular to the first direction.

Kingpin assembly with rotation sensor arrangement

A kingpin assembly includes a housing having a recess located therein, a kingpin having at least a portion located within the recess of the housing, wherein the kingpin is secured within the recess of the housing, and wherein the kingpin includes an axis extending along a length of the kingpin, and a sensor arrangement configured to sense a force exerted on the kingpin in a first direction that is substantially perpendicular to the longitudinal axis.

A vehicle component actuation arrangement includes a vehicle component movable between a first configuration and a second configuration, an actuator configured to move the vehicle component between the first configuration and the second configuration, and a pneumatic valve arrangement pneumatically coupled to a vehicle air supply line, a vehicle pneumatic source and the actuator, where the valve arrangement is configured to move the vehicle component between the first and second configurations via the actuator when an air pressure is removed from within the vehicle air supply line.

A fifth wheel assembly safety coupling arrangement includes a fifth wheel hitch including a top support surface and a recess configured to receive a kingpin member therein, a locking arrangement moveable between a locked position, wherein the kingpin is prevented from being removed from within the recess by the locking arrangement, and an unlocked position, wherein the kingpin is not prevented from being removed from within the recess by the locking arrangement, and a pneumatic cylinder assembly configured to receive a first pneumatic input from a first air supply exerting a first force on the pneumatic cylinder assembly, and a second pneumatic input from a second air supply exerting a second force on the pneumatic cylinder assembly, wherein the pneumatic cylinder assembly prevents the locking arrangement from moving from the locked position to the unlocked position when the sum of the biasing force and the first force is greater than the second force.

Fifth wheel assembly safety coupling arrangement

A storage arrangement for lines from a tractor truck includes a housing member secured external to a cab of the truck, a receiver connected to the housing and configured to couple to a select one of an electrical line and first and second pneumatic lines, and a control arrangement coupled to the receiver such that upon coupling of one of the lines with the first receiver the control arrangement activates a status indicator that provides the operator with an indication of a coupling status of the select one of the electrical line, the first pneumatic line and the second pneumatic line with the storage arrangement.

A storage arrangement for lines from a tractor truck includes a housing member secured external to a cab of the truck, a receiver connected to the housing and configured to couple to a select one of an electrical line and first and second pneumatic lines, and a control arrangement coupled to the receiver such that upon coupling of one of the lines with the first receiver the control arrangement allows an operator to at least one of release brakes of the truck, release brakes of a trailer, and unlock a kingpin from a fifth wheel hitch plate assembly, wherein the control arrangement prevents the operator from the at least one releasing the brakes of the truck, releasing the brakes of the trailer, and unlocking the kingpin from the fifth wheel hitch plate assembly prior to one of the lines being coupled with the receiver.

A trailer hitch arrangement control system including a trailer sensor for sensing the position of a trailer relative to a trailer hitch assembly, a lock sensor for sensing the position of a locking mechanism, a control valve in fluid communication with a brake assembly of a trailer and operable between closed and open positions, wherein the brake assembly is engaged and disengaged, respectively, and wherein the brake assembly is positively biased toward the engaged position, and a controller coupled to the trailer sensor, the lock sensor and the control valve for determining whether the trailer hitch assembly is properly coupled to the hitch and generating a control signal to the control valve to actuate the control valve from the open position to the closed position when the trailer hitch assembly is improperly coupled to the hitch, such that the brake assembly remains in the engaged position.

Fifth wheel coupler safety control system

A kingpin assembly comprises a housing having a recess located therein, a kingpin having at least a portion located within the recess of the housing, a collar member operably coupled to the kingpin, and a collet member extending about the kingpin and frictionally engaging the housing and the kingpin.

Fifth wheel hitch kingpin assembly

The fifth wheel hitch lube plate of the present invention comprises a perforated support member having a plurality of perforations and a lubricious material molded around the perforated support member such that the lubricious material covers both the top and bottom surfaces of the perforated support member and extends through the perforations formed in the perforated support member. Preferably, the support member is a perforated metal plate and the lubricious material is nylon, graphite, or an ultra-high molecular weight (UHMW) polyethylene material. The problems associated with utilizing nylon (or similar materials) and bonding it to a support plate are overcome by forming the plurality of apertures in the support plate so that a mechanical cohesive bond is formed between the upper and lower surfaces of the support plate, thereby substantially increasing the lube plate strength, and shear strength, while decreasing the likelihood that the lube plate may buckle.

Fifth wheel lube plate having a perforated support member

A kingpin assembly comprises a housing having a recess located therein, a collar member operably coupled to the housing, and an integral single-piece kingpin having at least a portion located within the recess of the housing, wherein the housing and collar cooperate to rotationally secure the kingpin within the recess of the housing, and wherein the kingpin provides a sole rotational support for the kingpin with respect to the housing and the collar.

Rotating fifth wheel hitch kingpin assembly

A fifth wheel hitch assembly includes a hitch plate having a rearward end that defines a throat for receiving a kingpin. First and second structural support ribs extend downwardly from a bottom surface of the hitch plate. A pair of ears extend longitudinally between the first and second support ribs. Each ear includes an aperture adapted to receive a pivot pin to pivotably support the top hitch plate on a supporting structure. Each ear is substantially offset from at least a selected one of the first support rib and the second support rib.
