What are the technical indicators of automobile production?

The main technical parameters of this car are:

I. Dimensional parameters

Length, width, height, wheelbase, wheel track, front suspension, rear suspension, minimum ground clearance, approach angle, departure angle, turning diameter, passage circle and swing value.

The Limits of Overall Dimensions, Axle Weight and Mass of Road Vehicles (GB 1589-2004) and Technical Conditions for Motor Vehicle Operation Safety (GB7258-2004) both stipulate the limit dimensions of road vehicles in China: the length of trucks, buses and double-axle buses is not more than12m, the width is not more than 2.5m and the height is not more than 2.5m..

Second, the quality parameters

1, axial load

Axle load refers to the vertical load of each axle to the ground when the car is fully loaded.

The national standard "Limits of Overall Dimensions, Axle Weight and Mass of Road Vehicles" (GB 1589-2004) and the national standard "Technical Conditions for Motor Vehicle Operation Safety" (GB7258-2004) stipulate that the maximum allowable axle weight of two-axle trucks shall not exceed10t; The maximum allowable axle load of passenger cars and trucks with more than three axles (including three axles) shall not exceed 10t.

2, the total mass of the car

The total mass of a car refers to the sum of its own mass when it is fully loaded and the loaded mass when it is fully loaded with passengers (including drivers) and goods according to regulations, also known as fully loaded mass.

Namely: total mass = self mass (kerb mass)+payload mass.

3. Load quality

Vehicle load mass refers to the rated load mass allowed when driving on hard and good roads.

When the car is driving on a gravel road, the load should be reduced (about 75% ~ 80% of the good road).

The loading quality of off-road vehicles refers to the loading quality of off-road driving or dirt road driving.

The load capacity of a car is expressed by the number of seats.

The capacity of urban buses is equal to the number of seats and includes the number of standing passengers (generally, the area of each bus is not less than 0. 125m2), and the area of buses in other cities is not less than 0. 15m2. The loading quality of coach and tourist bus is equal to the number of seats.
