The present invention proposes an integral balance shaft crossbeam, which includes connecting brackets at both ends, thrust rod supports, and a crossbeam functional part in the middle. The weight-reducing cavity and the connecting brackets at both ends are symmetrical structures, and the middle part of the connecting bracket is provided with a weight-reducing groove, and the mouth of the weight-reducing groove is connected by a reinforcing rib. The integral balance shaft crossbeam of the present invention is an integral structure formed by one-time casting, which overcomes the generally poor impact resistance of the existing connected balance shaft crossbeam; on the basis of ensuring performance, the purpose of weight reduction is achieved by setting a weight-reducing structure , each product can reduce weight by 20‑50%.
Description
technical field [0001] The invention relates to commercial vehicle parts, especially an integral balance shaft beam. Background technique [0002] Experiments have shown that if the weight of the vehicle is reduced by 10%, the fuel efficiency can be increased by 6%-8%; when the curb weight is reduced by 100kg, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6L. Reduce the self-weight of heavy trucks, reduce fuel consumption, reduce harmful substance emissions, save weight-based charges, increase load utilization coefficients, and increase transportation profits. After the weight of the car is reduced, the center of gravity of the car body can be lowered, and the driving of the car is more stable and comfortable. Lightweight can reduce rolling resistance, acceleration resistance and climbing resistance, and can also create conditions for realizing high power. [0003] Balance shaft suspension is one of the key components of commercial vehicles, and its light...
