摘要： A hitch system includes an upper hitch portion that is configured to couple to a trailer coupler portion and to a vehicle coupler portion to provide multiple degrees of rotational freedom as well as longitudinal coupling for towing the trailer by the vehicle. A weight distributing lower hitch portion couples to the upper hitch portion about a transverse axis. The weight distributing lower hitch portion includes spring bars extending to rearward points on a frame of the trailer between a tongue of the trailer and the axle of the trailer. The upper hitch portion and lower hitch portion are biased away from each other and hence bias the spring bars away from the trailer frame. The spring bars may then be coupled to the trailer frame by using respective levers to transfer weight distribution.

摘要： A trailer hitch device that includes a yoke assembly with a yoke section and a latch section, a latch assembly integral with the latch section with a latch pivot bolt, two latch plates pivotally connected by the latch pivot bolt and a horizontal coupling shaft having two external ends, where the external ends are dimensioned to fit into a vertical opening on the sides of latch section secured by the latch plates. There is also a trailer yoke that the horizontal coupling shaft passes through that can be securely and pivotally connected to the latch assembly by placing the horizontal coupling shaft in the vertical openings of the latch section, rotating the latch plates down over the horizontal coupling shaft and securing the latch plates in position and a longitudinal pivot rivet adjustably disposed on the vehicle side of trailer hitch device.
