As the country's cars and the saturation of the road network is changing the car park of the country by a specialization by type of transport, and on the road conditions. For example, cars are designed for long-distance traffic on roads with a firm and level surface, may not have a large margin of safety parts and assemblies, while the cars used for quarrying and transportation of building materials, which are constantly changing speed and direction of motion frequent braking and gear, should have a large margin of safety. Depending on the operating conditions, and are made in the design of the factors determining the basic nomenclature of the family car, can be created cars that differ in dry mass and weight in running order.
Increase the payload to the maximum of axial loads only by reducing the dry weight can be achieved with the application of lighter and stronger (or more expensive) materials and improving road conditions.
If the car is not based, specialized cars, the cars can be designed as a general-purpose lightweight construction with wheel 4X2 and 6X4, which will be widely used for local transportation during continuous operation on roads with improved surface even on flat terrain in the temperate climate zone.
For these conditions can have cars Daycab not have options specific to the north and south car performances. For these vehicles requires less engine power than those used for the long haul in any terrain. This is explained by the fact that in the local traffic (city and suburban area with a shoulder about 50 km) car does not need to develop high speeds (they are almost not possible to implement). |
