Abstract: The latch assembly of a fifth wheel hitch plate comprises a latch member movable between lock and unlocked positions, a plunger member movable between engaged and unengaged positions, an actuator movable between coupled and uncoupled positions, a locking member movable between first and second positions, and a biasing member that biases the locking member from the disengaged position to the engaged position, wherein the latch member abuts the locking member as the latch member is moved from the unlocked position to the locked position, thereby moving the locking member from the first position to the second position.

Abstract: A hitch coupler includes a frame having vertically spaced apart plates extending outwardly therefrom. Each plate includes a pin receiving aperture adapted to receive a pin member therethrough. The pin member is moveable between extended and retracted positions. The pin member includes a pin housing having a vertical guide slot disposed thereon. A lock mechanism is pivotally coupled to the frame member and includes a locking flange which is adapted to engage the guide slot when the pin member is in the extended position. The lock mechanism is biased towards a lock position such that the locking flange of the lock mechanism is adapted to automatically engage the guide slot disposed on the pin housing of the pin member when the guide slot is aligned with the locking flange of the lock mechanism. In the locked position, the locking mechanism acts to retain the pin member in the extended position.

Abstract: A vehicle suspension system includes a mounting bracket adapted to be secured to a vehicle frame, a trailing arm member pivotably coupled to the first mounting bracket, an axle member adjustable between a first pinion angle and a second pinion angle, an axle mounting assembly securing the axle member to the trailing arm member and including an upwardly disposed, curved abutment surface, and a stop member adapted to be operably coupled to a vehicle frame, the stop member including a downwardly disposed, curved abutment surface adapted to abut the abutment surface of the axle mounting assembly, thereby limiting travel of the trailing arm with respect to the vehicle frame to a constant value when the axle member is at both the first pinion angle and the second pinion angle.

Abstract: A drawbar assembly includes a mounting member adapted to couple to a vehicle and that includes a body portion having a first passage, an eye portion extending outwardly from the mounting body portion, wherein the eye portion includes a top surface, a bottom surface and a second passage extending therethrough adapted to receive a pintle hook therein, and a wedge member slidably received within the first passage of the body portion. The wedge member is slidably movable between a first portion, wherein the wedge member is withdrawn into the first passage of the body portion, and a second position, where the wedge member extends into the second passage of the eye portion. The wedge member is located between the top surface and the bottom surface of the eye portion, and does not extend above the top surface or the bottom surface.

Abstract: A fifth wheel hitch mounting assembly for mounting a fifth wheel hitch plate to a vehicle frame assembly includes a first and second frame members each having substantially vertically extending mounting portions each having an inwardly facing surface, comprises a first support member adapted to couple to the inwardly facing surface of the mounting portion of the first frame member, a second support member adapted to couple to the inwardly facing surface of the mounting portion of the second frame member, a cross member extending between and coupled to the first support member and the second support member, a first mounting member coupled with a first support member and including an inwardly exposed aperture adapted to receive a mounting pin therein for pivotally coupling a fifth wheel hitch plate to the first mounting bracket, and a second mounting member coupled to the second support member and including an inwardly exposed aperture adapted to receive a mounting pin therein for pivotally coupling the fifth w

Abstract: A fifth wheel hitch plate support assembly includes a rack member adapted to be mounted to a vehicle frame member, a mounting member slidably engaging the rack member and selectively repositionable along a length of the rack member, wherein the mounting member is adapted to pivotably support a fifth wheel hitch plate therefrom, a bracket member separated from the mounting member and slidably engaging the rack member, and a stop assembly operably supported by the bracket member and adapted to abut the fifth wheel hitch plate to limit a pivoting movement of the fifth wheel hitch plate with respect to the mounting member.
