An assembling structure for vehicle carrying device is provided, including: a tubular member, having an axial direction, configured to be inserted within a trailer hitch of a vehicle, a wall of the tubular member having a through hole; a first abutting member, being movable along the axial direction and disposed in the tubular member; an expansion mechanism, including a second abutting member movably disposed on the first abutting member, the second abutting member being located within the through hole and urgeable to move by the first abutting member; an actuating member, being connected with the first abutting member, configured to be externally operable to drive the first abutting member to move axially and urge the second abutting member to move radially.

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 hitch vibration dampener assembly and method of use thereof including a tow mount member including a base portion with a vibration dampener pad affixed to the back surface such that coupling of the tow mount member by locked engagement of at least one elongated pin successively received through paired side holes disposed in flanges of a hitch platform channel compresses vibration dampener pad upon the back panel of the hitch platform to thereby reduce the movement between the tow mount member and hitch assembly.

A hitch system for automatically coupling a hitch accessory that has an attachment bar assembly with a hitch receiver. The attachment bar assembly includes a housing bar that is tubular, with a pin-hole through the housing bar. A pin-lever is pivotably mounted in the housing bar and includes a pin configured to retract into the housing bar and to extend out of the pin-hole. A ramp-component is disposed in the housing bar and is engageable with the pin-lever. An actuator selectively moves the ramp-component to retract the pin into the housing bar and to extend the pin out of the housing bar, by selectively enabling pivoting of the pin-lever.

A hitch vibration dampener assembly and method of use thereof including a tow mount member including a base portion with a vibration dampener pad affixed to the back surface such that coupling of the tow mount member by locked engagement of at least one elongated pin successively received through paired side holes disposed in flanges of a hitch platform channel compresses a vibration dampener material upon the back panel of the hitch platform to thereby reduce the movement between the tow mount member and hitch assembly.

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.

An anti-rattle hitch device is described. A rotating barrel pin is positioned proximate to the normal accessory port of receiving hitch housing. The pin cooperates with resilient bushings that are engineered to compress in overload situations, while urging the accessory drawbar flush against the upper, inner facing of the housing when the device is engaged under normal conditions. The resulting apparatus prevents unwanted rattling and play of the hitch and accessory without the need for loose or removable parts.

This invention discloses a simple system of components that can be retrofitted to all standard receiver type hitches. It implements the very common round collet wedging principle to the square receiver tube using wedge shaped components to fill the gap between the receiver tube and the draw bar. The wedging action can be applied thru various combinations of differing components shapes. This invention does not modify the existing receiver or ball mount. The system can be adjusted to accommodate for changes after initial installation and previous wear. The wedging action provides forces to center the draw bar inside the receiver tube as well as lock it in place, resisting up/down, left/right, fore/aft movements. There are two basic configurations based on the method of attachment to the existing receiver. The wedge positioning action is the same for both.

The subject invention, a collet receiver hitch, has a receiver tube with collet features, and a collet collar to eliminate the problem movement of the draw bar/mount inside the receiver. The first part is a collet receiver tube with an open end for accepting the ball mount shank. The second part is an outside collet collar. The outside collet collar is drawn onto the collet receiver tube, thereby causing the wedging action that, in turn, centers and holds the mount shank. The hitch pin is still required, and its use does not impair the subject invention.

The present disclosure provides a bracket connecting structure. The bracket connecting structure includes a bracket mounting piece, a mounting tube connected with the bracket mounting piece, and a locking assembly arranged on the mounting tube. The locking assembly includes a locking piece, a driving piece and a driving fitting piece which are arranged in the mounting tube. The locking piece is arranged in the mounting tube in rotating connection with the mounting tube. The driving fitting piece is rotatably connected with the locking piece. The driving piece runs through the mounting tube and is adaptively connected with the driving fitting piece.
