A carrying rack connecting device is provided, including: an insertion assembly, configured to be connected with a hitch; an urging mechanism, including a pin, a driving member and at least one urging member, the pin configured to pin the insertion assembly and the hitch, the driving member being connected to the insertion assembly and movable between a release position and an urging position, the driving member including an urging portion, the at least one urging member being swingably connected to the insertion assembly and including an urged portion, the urged portion and the urging portion partially overlapping, wherein when the driving member moves from the release position toward the urging position, the urging portion urges the urged portion to move the at least one urging member to swing outward so that the at least one urging member is urgingly abutted against the hitch.

The present disclosure belongs to a towing device with a damping function. The towing device includes a towing main body and a towing assembly mounted on the towing main body; the towing main body includes a towing cantilever and a vertical adjustment arm arranged at an end part of the towing cantilever; one end of the towing cantilever is connected to the vertical adjustment arm, and the other end is provided with several fixing holes; the towing cantilever is fixed, through fixing pins, on a fixed seat pre-arranged at a rear end of a towing vehicle; a cushion is sleeved on the towing cantilever. The cushion fills a gap between the tightening screw and the fixed seat, and an activity space where the fixing pins are threaded into the fixing holes is also greatly narrowed; the axial movement of the towing cantilever after the mounting is restrained.

A vibration minimization towing hitch includes a shank attachable into the receiver tube the towing vehicle, and a separately formed head, such as for supporting a tow ball. The head is pivotable through a partial range of motion relative to the head, such as allowing the tow ball to pivot up to 7° downward or up to 3° upward. One or more compressible inserts are disposed in a pocket between the shank and the head, for resisting the limited pivotal motion of the head relative to the shank. A user performs a part of the assembly using two insertable pins or bolts, with insertion of the second pin compressing a compressible bumper which is separate from the insert(s).

A silencer assembly for trailer hitches and a method of use thereof. The silencer assembly includes a sheet of material that is durable, abrasion-resistant, wear-resistant, ultra-violet light resistant, and sound dampening. An adhesive is applied to a bottom surface of the sheet which is then placed on a portion of the drawbar that is selectively receivable in a bore of receiver tube of the trailer hitch. The adhesive fixedly secures the sheet to the drawbar. The drawbar is inserted into the receiver bore. The sheet occupies part of a gap defined between an exterior surface of the drawbar and an interior surface of the receiver tube reducing relative movement between the drawbar and the receiver tube, and thereby reducing rattling noises. An additional sheet of material and one or more shims may be used to further reduce the gap between the drawbar and receiver tube, and thereby further reduce rattling.

A hitch assembly comprising a receiver having an opening for receiving a hitch member, an anti-rattle member secured with respect to the receiver, and a hitch member comprising a hitch body configured to be received by the receiver, and an engagement portion, wherein when the hitch body is received by the receiver, the engagement portion bears against the anti-rattle member causing at least a portion of the anti-rattle member to resiliently deform in a manner that a reaction force from the resilient deformation causes the hitch body to bear against the receiver.

A multiple hitch assembly and method of use thereof including a hitch platform having a channel member and multiple hitch member having a block base. A dampening member may be affixed such that coupling of the multiple hitch member by locked engagement of received through holes of the block base and paired side holes disposed in flanges of the channel member compresses the dampening member upon the recessed column of the hitch platform to absorb and thus attenuate the load and associated torque imparted by movement and rub between the hitch platform and multiple hitch member to thereby reduce associated rattle noise, and vibration.

A hitch tightening pin system is designed to attach a draw bar to a hitch receiver tube and prevent relative motion between the draw bar and receiver tube. The pin system has an elongate tapered shoulder bolt that has a larger and smaller outer diameter with a tapered surface extending between the larger and smaller outer diameter. The system includes an expansion sleeve that has arcuate portions. The expansion sleeve can slide onto the smaller outer diameter with the arcuate portions facing the tapered surface. A nut tightens to move the arcuate portions radially outwardly to apply force to the inside surface of a draw bar. The application of force causes the draw bar to be held tightly to the receiver tube and reduce or eliminate looseness or rattling during use.

The present invention relates to a hitch receiver alignment system having a first opening extending through and arranged upon a surface of the hitch receiver, a piston, a cylinder having a second opening adjoined to the hitch receiver, and a cylinder head having a third opening that is adapted to receive an alignment member that is manually adjusted by a user to contact the piston. As the user manually adjusts the alignment member, the piston consequentially is moved within a first opening extending through the hitch receiver. With the hitch being locked within the hitch receiver by a hitch pin, as the piston contacts the hitch within the hitch receiver the hitch is rotated about the hitch pin and a gap between the hitch and the hitch receiver is eliminated.

An improved anti rattle hitch pin assembly for a trailer hitch assembly enables a threaded member to be inserted into the shank receiver, and allows for an easy alignment of a threaded device to the side hole of the shank receiver. The anti-rattle hitch pin assembly includes an arc-shaped retainer wire, a threaded receiver pin, a threaded member, and an optionally lockable member. The threaded member can be easily moved to the alignment position once the internal components of the hitch pin assembly including the retainer wire has been inserted inside the shank receiver tube.
