Analysis of trucks

The power and fuel economy of a truck depend to a large extent on the performance of the engine and the selection of transmission type and parameters, that is, on the degree of reasonable matching of the power transmission system of the truck. Even if an engine has good performance, it cannot give full play to its performance without a properly matched transmission system. A transmission system that can be reasonably matched with the engine can make the engine often work near its ideal working area. However, due to the complexity of the problem and the contradictions and constraints between the power and fuel economy of the truck, the power transmission of the truck The design improvement of the system became a very complex multi-variable optimization problem. After analogy analysis, it was found that the truck had the following problems:
1) The vehicle speed, one of the vehicle's dynamic indicators, is low. In order to improve transportation efficiency, most vehicles choose to drive on the highway, so it must be increased accordingly;
2) If the car is often in a situation where it is necessary to accelerate to overtake, the original car's starting acceleration time and overtaking acceleration time are too long, and the car and the overtaken vehicle are parallel for too long when overtaking, it is easy to cause an accident and make the overtaking process difficult. Very dangerous;
3) The fuel consumption per 100 kilometers of the original vehicle is relatively high when driving in multiple cycles. In order to reduce fuel consumption, the relevant parameters of the transmission system need to be optimized.
