The AMG SPEEDSHIFT PLUS 7G-TRONIC facilitates an optimum conversion of output into tractive power
by the automatic transmission with barely any perceptible shift times for extremely sporty power transmission.
The new drive boasts a spontaneous response to accelerator pedal commands, high tractive power
(400 Nm max.
The control speed is a result of power balance between downhill gravity tractive power
and total vehicle retarding power.
In most tractors, approximately 60% to 65% of the power generated by the engine is transformed, effectively, into tractive power
A 70% efficiency is assumed for capturing RB energy and later returning that energy to the wheels for tractive power
The Zetros is equipped with a two-stage transfer gearbox withan off-road gear ration of 1:1.69, increasing tractive power
under the most extreme conditions by almost 70%.
A West Midland firm which is already reaping the benefits of doing business in Brazil is Staffordshire company Tractive Power
, which specialises in battery-powered electric vehicles designed to push, pull and manoeuvre loads of up to 50 tonnes.
It features a 1.1 kW hydrogen fuel cell that feeds batteries of 4.3kWh capacity to provide tractive power
. This inventive solution impressed the judges last year but failed to win.
The Mercedes 9G-TR0NIC transmission--a nine-speed that features a torque converter with an efficiency of converting engine power to tractive power
of 92%, which is an improvement over the circa 2003's 7G-TRONIC's of 85%--required the development of some sophisticated metalcutting in order to be built.
Shortly after its independence, Zimbabwe received more than $41 million (in two tranches in 1981 and 1982) so that its parastatal, National Railways of Zimbabwe could increase tractive power
by acquiring new locomotives.
The battery pack provides electrical energy to the motor which in turn generates tractive power
. Besides, the engine operates on a constant speed, constant load mode, maximising engine efficiency irrespective of large variation in vehicle speed and frequent stops and starts.
