In order to solve this technical problem, the utility model provides an engineering vehicle Yuanbao beam assembly, including a connecting bracket, a reinforcing bracket and a channel beam. It is an L-shaped structure, and the two connecting brackets are symmetrically arranged at both ends of the channel beam using bolts and nuts. The bending part of the connecting bracket is welded with a reinforcing bracket; the connecting bracket is provided with a round hole and a mounting hole, and the round hole is used for The installation tool for the Yuanbao beam assembly is put on and removed, and the mounting holes are used for connecting and installing the Yuanbao beam assembly and the combined bracket of the front suspension.

The two sides of the channel beam are downwardly curved beam walls, and the beam walls are provided with a plurality of side lightening holes; the upper bottom of the channel beam is provided with a lower lightening hole.

A round hole and four installation holes are arranged on the connecting bracket.

A reinforcement plate is provided between the two beam walls at the bottom of the channel beam.

The channel beam is a left-right symmetrical structure with both sides bent down.

The Yuanbao beam assembly is connected to the front spring combined bracket through connecting bolts, and the front spring combined bracket is connected to the frame longitudinal beam through connecting bolts.

Beneficial effects: the utility model improves the torsional strength of the vehicle frame, reduces the manufacturing cost of the ingot beam, avoids the use of large molds, is convenient for installation and maintenance, and has low maintenance costs in the later period. The Yuanbao beam assembly has simple processing technology, avoids the use of large molds, is easy to install, and has low maintenance costs. It can improve the torsional strength of the frame and meet the needs.
