The clue factors in your daily Works are very demanding, and the service it´s always compromised with the Administration, also the distance between stops, the capacity and the control of costs in you exploitation (engines, coachbuilders, gearboxes, acids corrosion…).
Theones you normally use are ZF (or Iveco) with 6, 8 and 9 speeds. The life or behavior on these gearboxes, can be affected mainly by the following: oil level, the clutch and the gearshift lever. You must take into account that the excess of the stops and starts, can damage or can cause the deterioration in the clutch, and because of that, the performance in the gearboxes and clutches can be severely affected. Other factors like the way of driving, are clearly determined for optimizing their life…that´s why it is good to have settled the drivers scheduled.
These gear boxes work without the clutch pedal, working directly from an electronic device and a pneumatic unit in charge of giving the gear changing the order to the “actuators”, depending on the information received from the different sensors. The actuator, function as the foot and activates the clutch (the same as the one installed in a mechanical box) making possible to change the gears, or that have been programmed or the ones wished. They can also have Intarder or Retarder, together with its cooler. The main brands are ZF, Volvo, Scania and Mercedes Benz.
These gearboxes completely eliminate the action of driving, because their maintenance in more specific, becauise they have to have the correct oil level and keep it in the best condition possible. This is the reason why the oil is for the gear box, what the blood is for the human body, because not only works as a lubricant for the different parts but it also protects them absorbing the energy produced by the contact pressure and the thermic energy produced by friction transforming the energy in the torque converter and the retarder integrated , it also have to have the necessary additives to preserve it from pollution and the loss of properties that might affect the capacity of pressure and loss of thermic energy. The same way the cooler has an important role in the gear box performance. These types of gear boxes require a keypad, a switchboard, a cooler and various sensors who can provide information and an electric installation capable of allowing communication between the electronic components of the bus. The most common used brands are ZF and ALLISON.
A part from the gear box, other components that you have installed and which Autosur knows perfectly well are:
