Abstract
A motion absorbing hitch for dampening forces on a towing vehicle from movement of a trailer assembly towed by the towing vehicle includes a towing attachment assembly coupled to a towing vehicle, a trailer attachment assembly pivotally coupled to the towing attachment assembly and adapted for coupling to a trailer assembly, and a shock absorbing assembly coupled between the towing attachment assembly and the trailer attachment assembly to dampen pivoting between the towing attachment assembly and the trailer attachment assembly.
Claims17
A force dampening hitch assembly comprising:
- a towing attachment assembly, said towing attachment assembly being adapted for coupling to a towing vehicle;
- a trailer attachment assembly pivotally coupled to the towing attachment assembly, said trailer attachment assembly being adapted for coupling to a trailer assembly;
- and
- a shock absorbing assembly coupled between the towing attachment assembly and the trailer attachment assembly to dampen pivoting between the towing attachment assembly and the trailer attachment assembly;
- wherein said towing attachment assembly includes a main portion and a shock attachment arm extending from said main portion, said shock absorbing assembly extending between said shock attachment arm and said trailer attachment assembly;
- wherein said shock attachment arm extends from a proximal end of said main portion back towards a distal end of said towing attachment assembly;
- said shock absorbing assembly including a shock absorber having a first end pivotally coupled to said towing attachment assembly and a second end pivotally attached to said trailer attachment assembly;
- said trailer attachment assembly including a pair of flanges forming a generally L-shaped main section having a first end pivotally coupled to said towing attachment assembly;
- and
- a trailer attachment means extending from a second end of said generally L-shaped main section for coupling to the trailer assembly.
