An energy dampening drawbar for use with receiver hitches and specialty types of hitches is described as including an elongated hollow shank having slots on opposite sides. A first cushion block is located within the shank and has a portion of the first cushion block adjacent one surface of a pin block. The pin block has a hole that aligns with a portion of the two slots. A second cushion block is located within the shank adjacent another surface of the pin block. A first restraint prevents longitudinal travel within the shank by the first cushion block. A second restraint prevents longitudinal travel within the shank by the second cushion block. A plate is attached to one end of the shank to provide a surface for attaching a trailer coupling.

Le dispositif de blocage comporte un orifice pouvant s'aligner partiellement avec les fentes. Un deuxième bloc amortisseur, placé à l'intérieur du tube, est contigu à une autre des surfaces du dispositif de blocage. Un premier dispositif de retenue empêche le déplacement longitudinal du premier bloc amortisseur à l'intérieur du tube.
