In 2022, tractor lightweight is the focus of reducing fuel consumption and improving endurance, and it is also to reduce the weight of the vehicle under the premise of ensuring the strength and safety performance of the vehicle, which will become an important technical development direction for the vehicle and parts market in the future. As a result, the Dayun V7 came into being, not only youthful and beautiful in appearance, but also in the field of lightweight also led to new technological innovations.
First of all, the car chassis is a combination of four parts: transmission system, driving system, steering system and braking system, and carries 70% of the weight of the body, while chassis lightweight is an important area of vehicle lightweight;
Secondly, as one of the core components of the car, the lightweight chassis helps to reduce the weight under the spring, thereby improving acceleration, handling and comfort;
The chassis system mainly reduces the weight of the chassis through the integrated design of parts, reduces the type of parts and the application of new materials, and realizes the weight reduction of the chassis; the following is its prominent point:
1. Integrated design of middle beam and thrust rod support
The integrated beam assembly adopts QT800-5 high-strength ductile iron integral casting, which combines the traditional thrust rod support and beam assembly into one, and reduces the weight by more than 60kg compared to the traditional stamped beam assembly, so as to maximize the weight reduction of the chassis
2. Integrated design of lower pocket beam
The leaf spring rear bracket and the hood beam are designed from the split structure into an integrated structure, which greatly saves the space for the layout of the whole vehicle on the one hand, and improves the torsional stiffness of the frame on the other hand.
3. Integrated design of front leaf spring bracket and pipe beam
The leaf spring bracket and pipe beam assembly are designed from the split structure into an integrated machine structure, which can reduce the weight by 15kg.
4. Application of new materials with high strength leaf springs
The leaf spring is made of high-strength spring steel SDS1500 material, tensile strength ≥ 1600MPa, yield strength ≥ 1400MPa, and 6000km enhanced pavement verification at the national test site, which is equivalent to the user's reliable driving of 300,000km on secondary and above roads (safety guarantee).
Choosing V 7 is equivalent to seizing the market opportunity, the appearance is youthful, the whole vehicle is light, safe and reliable, the handling is comfortable, and the heavy trucks in this era should look like it has, which is the heavy truck imagined by the card friends.
Big Luck V 7, V Come Can 7!
