A mounting arrangement (1; 101; 201) for mounting a trailer coupling to a tractor vehicle with a chassis that has a pair of rearwardly extending opposite left and right frame side members (9, 11; 109, 111; 209, 211) that includes opposite left and right bearing blocks (5, 7; 105, 107; 205, 207). The opposite left and right bearing blocks (5, 7; 105, 107; 205, 207) each have a support surface and a pivot bearing for being fixed directly or indirectly to the chassis of the tractor vehicle. A coupling saddle plate (3; 103; 203) is pivotally mounted from the opposite pivot bearings of the left and right bearing blocks (5, 7; 105, 107; 205, 207), while a diagonal cross brace (35; 135; 235) is provided between at least one of the left and right bearing blocks and a respective one of the transversely opposite right or left frame side members (9, 11; 109, 111; 209, 211). The diagonal cross brace (35; 135; 235) comprises at least one diagonally extending leg (39, 41; 139, 141) that is adapted to extend laterally inwardly and diagonally downward from at least one of the left and right bearing blocks (5, 7; 105, 107; 205, 207). |

1. Method of mounting a trailer coupling, including the steps of:
providing a tractor vehicle having a chassis with a pair of rearwardly extending opposite left and right frame side members; providing left and right bearing blocks, each having a support surface and a pivot bearing; fixing each of the left and right bearing blocks to the chassis of the tractor vehicle; providing a coupling saddle plate and pivotally mounting the coupling saddle plate from the opposite pivot bearings of the left and right bearing blocks; providing a diagonal cross brace between at least one of the left and right bearing blocks and a respective one of the transversely opposite right or left frame side members; providing the diagonal cross brace with a first diagonal leg, extending laterally inwardly and diagonally downward from the left bearing block and with a second diagonal leg, extending laterally inwardly and diagonally downward from the right bearing block; and providing a chassis traverse between the opposite left and right frame side member, and joining inward ends of the first and second diagonal legs to the chassis traverse. |
