Embodiment Construction
[0020] A truck tail beam for a full trailer, including a tail beam, the improvement is that: the tail beam is composed of an upper beam 1 and a lower beam 2; the upper beam 1 is a plate-shaped structure with an L-shaped cross section ; The lower beam 2 is a plate-shaped structure with an L-shaped cross section; the upper beam 1 and the lower beam 2 are stacked together to form a U-shaped plate-shaped structure; the upper beam 1 and the lower beam 2 overlap A towing connection hole 7 is provided at the position, and the towing connection hole 7 is a through hole, and the towing connection hole 7 runs through the overlapping portion of the upper beam 1 and the lower beam 2 .
[0021] Further, an outer reinforcing plate 3 is provided on the outer surface of the overlapping portion of the upper beam 1 and the lower beam 2. The outer reinforcing plate 3 is a plate-like structure with a U-shaped cross section. The outer reinforcing plate 3 connects the upper beam 1 It is clamped wit...

The invention relates to a truck tail beam used for overall pulling, and the truck tail beam comprises a tail beam, wherein the tail beam is composed of an upper beam and a lower beam, the upper beam is of a platy structure body with an L-shaped cross section; the lower beam is of a platy structure body with an L-shaped cross section; the upper beam and the lower beam are stacked up together to form a platy structure body with a U-shaped cross section; the overlapped part of the upper beam and the lower beam is provided with a pulling connecting hole, the pulling connecting hole is a through hole, and the pulling connecting hole penetrates through the overlapped part of the upper beam and the lower beam. The truck tail beam used for overall pulling provided by the invention has the beneficial technical effects that the manufacturing difficulty and production cost of the tail beam are reduced and the structural strength of the tail beam is improved.
Description
technical field [0001] The invention relates to a frame structure of a heavy-duty vehicle, in particular to a rear beam of a truck used for a full trailer. Background technique [0002] In the prior art, the rear part of the frame of a heavy-duty vehicle used as a tractor is provided with a tail beam, which is used to mount a trailer; the existing tail beam structure is a single-layer integral "U"-shaped sheet metal structure, This structure requires a large forming mold to be manufactured, and the processing investment is high, and the bearing capacity is low. Contents of the invention [0003] Aiming at the problems in the background technology, the present invention proposes a tail beam for a full-trailer truck, including a tail beam, and its improvement is that: the tail beam is composed of an upper beam and a lower beam; the upper beam is a cross-section An L-shaped plate structure; the lower beam is an L-shaped plate structure; the upper beam and the lower b...
