The outside is welded with a fixed bracket, and the top of the left bracket is welded with a water tank left installation bracket.

The right bracket and the left bracket are symmetrical structures, including a right vehicle frame connecting bracket, a crossbeam right connecting bracket, a fixing bracket and a water tank right mounting bracket.

The left bracket and the right bracket are respectively assembled on the front end of the left vehicle frame and the front end of the right vehicle frame through the left vehicle frame connecting bracket and the right vehicle frame connecting bracket.

The front crossbeam assembly includes a front crossbeam and a crossbeam that are welded as one, connecting plates are welded at both ends, and a reinforcing bracket is welded between the crossbeam and the connecting plate. bracket and right bracket connection.

Reinforcing ribs are welded on the outer sides of the bends of the left vehicle frame connecting bracket and the left crossbeam connecting bracket, as well as the right vehicle frame connecting bracket and the crossbeam right connecting bracket.

The left frame connecting bracket of the left bracket and the left crossbeam connecting bracket, the right frame connecting bracket and the crossbeam right connecting bracket of the right bracket are all integrated structures made of steel plate stamping and bending.

Beneficial effects: the left bracket and the right bracket of the utility model adopt a bending stamping structure with increased width and a welded beam structure, which increases the space at the front end of the frame and facilitates the assembly of the water tank. Fracture, and avoid cracks or even fractures due to long-term stress, while reducing the weight of the front cross beam connection device assembly of the frame, improving the safety of the front cross beam connection device, and reducing costs.
