A vehicle suspension system includes a first trailing arm assembly and a second trailing assembly each including a mounting bracket adapted to be secured to a vehicle frame and a trailing arm member pivotably coupled to the associated mounting bracket and adapted to be operably coupled to an axle member, wherein the trailing arm members each include an aperture extending therein, wherein the aperture has a relatively constant cross-sectional configuration along a depth thereof. The vehicle suspension system further includes a torsional member extending between the first and second trailing arm members and frictionally secured within the apertures thereof, wherein the torsional member has a relatively constant cross-sectional configuration along a length thereof that is received within the apertures of the trailing arms.

A trailer hitch assembly includes a receiver portion including a cylindrically-shaped cavity, a bushing member received within the cavity of the receiver portion, and a hitch member that includes a shaft pivotally received within the bushing member. At least a selected one of the bushing member and the shaft is constructed of a material that substantially eliminates the need for using a separately applied lubricant during use of the trailer hitch assembly. The hitch member also includes a first jaw member, a second jaw member coupled to the first jaw member and operable between open and closed positions, a primary latch coupled with the second jaw member and operable between a locked position preventing opening of the second jaw member, and an unlocked position allowing opening of the second jaw member, and a secondary latch coupled with the primary latch and operable between a locked position preventing unlocking of the primary latch, and an unlocked position, wherein the primary latch may be moved to the unlocked position thereof.

Trailer hitch assembly

A hitch coupler () including an E-shaped frame (), a pin () and a conical spring (). The frame () includes a back plate (), a top plate (), a middle plate () and a bottom plate (). The top (), middle () and the bottom () plates include aligned openings. The pin () extends through the aligned holes () in the top (), middle () and bottom () plates, with the pin () being configured to slide within the aligned openings (). The conical spring () surrounds and engages the pin (). The conical spring () biases a bottom of the pin () through the middle plate () and the bottom plate (). The pin () includes a retainer () that extends through a slot () in the top plate () as the pin () is pulled against the bias of the spring (). The retainer () abuts against a top of the top plate () when the retainer () is located above the top plate (). The retainer () is located between the pin () and the spring ().
