Technical Field

[0001] The utility model relates to the technical field of tractor frames, in particular to a tractor reinforced frame. Background Art

[0002] A tractor is a large truck or semi-trailer that is towed by tools between the front and the carriage. That is, the front of the vehicle can be detached from the original carriage to tow other carriages, and the carriage can also be detached from the original front and towed by other fronts. The front of the vehicle with driving ability is called a tractor, and the vehicle without traction driving ability at the back is called a trailer. The trailer is towed by the tractor. The connection between the tractor and the trailer is divided into two types: semi-trailer and full-trailer. Among them, the front half of the trailer is placed on the traction saddle on the rear section of the tractor, and the bridge behind the tractor bears part of the weight of the trailer. This is a semi-trailer. Therefore, when the tractor is semi-trailer, a frame is needed to carry the trailer.
