General trends in commercial vehicle development |
 |
|
|
|
The decisive factors determining developments
in the commercial vehicles sector are
Engine power
Engine torque
Engine speed
Axle transmission ratios
Weights
Sound insulation
Environmental protection
|


|
In all vehicle categories and weight classes
engine power and torque are being increased.
Engine speeds are reduced accordingly.
|


|
|
Since noise levels have to be lowered, fuel consumption
reduced and efficiency optimized, the
trend is towards slow-running engines and
power trains with the lowest possible number of
gear selections. Axle-ratios are also decreasing.
|


|
Over the recent years vehicle unladen
weights have decreased across the board,
permitting higher maximum pay loads. In
addition, new legislation has permitted
higher axle loads and higher total loads of
tractor/trailer rigs.
|
Keeping pace with these trends, we have tailored
the design and dimensioning of the new Compact 2000
cardan shaft series to the specific requirements of the market.
