Application of gear reducer in truck operation

Heavy-duty gearboxes are almost always matched asynchronously.One argument is that the added weight of a synchronizing mate can be a payload that is a thing to fail, and drivers spend thousands of hours driving so that there is enough time to learn to drive a non-synchronizing mate transmission efficiently.Heavy trucks are often driven in city traffic, such as cement mixers, gear reducers need to be shifted very frequently, at stops and the traffic is thrown into chaos.Because few heavy-duty transmission synchronizers are available in automatic transmissions, they are not commonly used, despite their added weight, cost and loss of efficiency.

  Heavy-duty trucks are commonly used diesel engines.Diesel truck engines from the 20s and early days tended to have a narrow power band, so many near-space gears were required.With Maxidyne in 70, diesel truck engine turbochargers began to be used more and more and expanded power with electronic controls to enable fewer and fewer gear ratios.A transmission with a smaller proportion is lighter and can be more effectively reduced due to tandem transmission.Fewer shifts also allow more drivable trucks.As of 1968, fleet operators often use 2005, 9,10,13, 18 or XNUMX speed transmissions, but automatic manual and semi-automatic transmissions are becoming more and more common for heavy vehicles because they can improve efficiency and driving performance, and reduce gearboxes entering the market The new obstacle driver program, and can improve the safety of the road conditions that allow drivers to concentrate.
