Long-Haul Freight Transportation Scenario

Industry Background

The global long-haul freight transportation market exceeds US$4 trillion. Truck engines need to operate continuously for over 100,000 kilometers, requiring extremely high fatigue strength and thermal stability of components. Traditional components often experience problems such as thermal fatigue cracking and bearing wear.

Dingjia Solution

Our heavy-duty truck crankshafts utilize bainite isothermal quenching technology, increasing fatigue strength by 50%. The connecting rod assembly features a bionic streamlined design, improving oil flow efficiency by 20% and heat dissipation performance by 15%. All products are compatible with heavy-duty trucks such as Volvo FH and Scania R series.

Product Advantages

• Crankshaft journal surface roughness reaches Ra0.2, reducing friction loss by 18%

• Connecting rod bearings use a three-layer composite material, increasing load capacity by 30%

• Carbon fiber air filter box reduces intake resistance by 25%, extending filter element life by 2 times

Customer Feedback

“After using Dingjia's crankshaft components, our truck fleet's fuel consumption per 100 kilometers decreased by 1.2L, annual maintenance costs decreased by 40%, and the 45-day delivery cycle perfectly matches our spare parts turnover needs.” – Operations Director of a large European logistics company
