Description

A heavy-duty vehicle frame beam assembly

technical field

The utility model relates to a heavy-duty vehicle frame crossbeam assembly, which belongs to the technical field of heavy-duty vehicle components.

Background technique

When repairing the transmission of a heavy-duty vehicle, the transmission needs to be hoisted, so the beam above the transmission needs to be easily disassembled. The crossbeam assembly generally includes a crossbeam body and a crossbeam connecting plate, the two are riveted, and then assembled on the frame longitudinal beam by bolts and rivets. Therefore, the crossbeam assembly of this structural form is not easy to disassemble. In order to facilitate the lifting of the transmission, when designing the frame, the crossbeam assembly above the transmission was moved back to avoid the transmission, which resulted in low torsional stiffness in the middle and front part of the frame (near the transmission), which caused poor driving conditions of the vehicle. At the same time, the longitudinal beam and the front beam of the vehicle frame assembly are prone to deformation or fracture, which is the weak point in the prior art.

Contents of the invention

The technical problem to be solved by the utility model is to provide a heavy-duty vehicle frame beam assembly that is easy to disassemble in view of the deficiencies in the prior art.

This solution is achieved through the following technical measures: the heavy-duty vehicle frame beam assembly includes a beam body and a beam connecting plate fixedly connected to both ends of the beam body, the beam connecting plate is fixedly connected to the beam body through a transition support, The middle part of the inner side of the beam connecting plate is provided with a slope-shaped boss, and the transition support is provided with a U-shaped notch matching the shape of the slope-shaped boss, and the transition support is connected to the slope-shaped convex of the cross-beam connecting plate through the U-shaped notch. The platform is fixedly connected, and the other end of the transition support is fixedly connected with the beam body through a connecting piece.

The above-mentioned transition support is a groove-shaped steel plate stamping part, and a sleeve is arranged in the middle to cooperate with its two sides, and the strength of the transition beam is strengthened through the sleeve.

The above-mentioned beam body is a groove-shaped steel stamping part with flanging, and the transition support and the beam body are respectively provided with through holes corresponding to the position of the sleeve, so that the connecting bolts pass through the through holes to connect the beam body, transition support and sleeve. The cylinders are connected together.

The connecting piece includes a connecting bolt matched with the through hole and the sleeve, and a nut matched with the connected bolt.

The above-mentioned transition support is welded with the beam connecting plate.

A wiring hole is arranged in the middle of the above-mentioned slope-shaped boss, and the wiring hole is convenient for passing through the brake pipeline and the wire harness of the whole vehicle.

A small hole is provided below the slope-shaped boss on the connecting plate of the crossbeam to facilitate the outflow of rainwater.

The beneficial effects of the utility model:

(1) The transition support is fixedly connected to the beam body through the connecting piece, which is easy to disassemble.

(2) The end of the transition support with a U-shaped notch is welded on the slope-shaped boss of the beam connecting plate. When the frame is twisted and deformed, the transition support and the cross-beam connecting plate bear shear force, and the slope-shaped boss The slope part bears most of the shear force, so the overall torsional strength of the beam is improved, and the weld is not easy to crack.
