curb weight of the car, that we used to say before the “empty weight.” The so-called car’s curb weight refers to vehicles at the factory conditions of complete technical equipment (such as a spare tire, tools, etc. installed in place), the weight of the various oil and water fill up. This is an important design specifications of the car.
1. The relationship between the total mass of the
total vehicle mass (G) is an automobile equipped, in accordance with regulations, weight of goods loaded passengers (including the driver).
to determine the total mass of the car
for the car, curb weight + = total mass of the car driver and the passenger baggage mass + mass
For passenger cars, automobile curb weight = total mass of the driver and passenger baggage quality + quality + + quality accessories
for trucks, total vehicle curb weight = mass of the driver and his assistant quality luggage + quality +
vehicle weight utilization coefficient
this is an important evaluation index (for trucks). It is the ratio of the total mass of the car with the dry weight of the car. The so-called dry weight refers to the empty car at the car without coolant, fuel, oil, spare tire and tools and accessoriesVehicle weight. Obviously, in the case where the same mass of the carrier, the dry weight is smaller, the quality factor by using higher car, the higher the efficiency of its transport. EQ1092F mass utilization factor is about 1.22. With the development of automotive materials and manufacturing technology, design technology, automobile weight use factor has increasing trend. Axle load
car assignment
refers to the mass of the vehicle front axle, the rear axle proportion. The principle of axle load distribution is based on the uniform wear and performance needs major automobile and automobile tires layout pattern determined. In order to make uniform wear of the tire, each tire is generally desirable to load substantially equal when full. For example, a single rear axle 4 × 2 car tires, it is desirable to charge around the axis of the shaft 50 each percentage, and the twin rear axle of the car, the front and rear axle load is desirable axis by 1/3 and 2/3 ratio to allocate. In fact, only approximately satisfy these requirements, e.g., general trucks, front axle load distribution of about 28 to 30 percentage.
2. Compare curb mass loaded
trim
i.e. vehicle equipment quality, also known weight. I.e. no car occupants or cargo, with only a spare tire tool, by weight of filled fuel and cooling water.
Quality loaded
loaded mass, i.e., the total mass loaded, also referred to the total weight. That is when the weight of the fully loaded car include: vehicle weight, people and goods. If your vehicle to pull the goods, it is necessary to consider the total weight and the weight difference is. Load mass
vehicle (carrying capacity)
This is one of the basic parameters of the vehicle. It is related to transportation vehiclesEfficiency, transportation costs, ease of use, product serialization and production equipment, and many other aspects.
to determine the load weight of the car should consider the following factors
① must be compatible with the purposes and conditions of use vehicles;
② various models of the deadweight should be reasonable classification, in order to facilitate serialization of products, GM and standardization.
③ can be used to take into account the extent and size of existing production equipment and production line changes.
