The Hydraulic Torque Converter In VW Tiguan Tsi For Sale Should Provide Ease To Driver
The automatic change is a transmission system of VW Tiguan tsi for sale should be capable by itself of selecting all gears or relations without the need for the direct intervention of the driver. The change from one relationship to another occurs as a function of both the speed of the vehicle and the speed of the engine so that the driver does not need either clutch pedal or shift lever.
The Accelerator Pedal
The simple act of stepping on the accelerator pedal causes the change in ratio as the engine varies in speed. The result that the driver appreciates is that of a comfortable change that does not produce jerks and that allows him to pay full attention to traffic. Therefore the automatic change not only provides more comfort but also gives the vehicle greater active safety. The fundamental elements that make up most of the current automatic changes are: a hydraulic torque converter that varies and automatically adjusts its output torque, to the torque that the transmission needs; an epicyclic train or a combination of them that establish the different relations of change; a control mechanism that automatically selects the relationships of the epicyclic trains. This control system can be either mechanical, hydraulic, electronic or a combination of them.
Possibility To Choose
Precisely the electronic control is the wonderful innovation available in the current automatic changes giving the driver the possibility to choose between several driving programs by means of a selector lever, nowadays there are control systems that can automatically select the very suitable gear change program for each specific driving situation. Among the data that these systems use for their calculations are, the frequency with which the driver steps on the brake, the slope of the road, the number of curves of the same, etc. Before studying the operation of the automatic gearbox, it is necessary to explain individually, the basic elements that form it. Besides, the hydraulic clutch that later evolved called torque converter, acts as an automatic clutch between the engine and the gearbox that, in these cases, is usually automatic or semi-automatic. This clutch allows the engine to turn at idle (no load) and also transmits the engine torque when the driver accelerates. It is based on the transmission of energy that a centrifugal pump communicates to a turbine through a liquid that is usually mineral oil.
The Hydraulic Clutch
To understand the principle well, we can give the example of two fans placed in front of each other. The wired fan, connected to the network, moves the air and projects it as an impeller or pump on the other fan (non-wired) that is not connected; the latter, when receiving the air, begins to turn like a turbine. So, a buyer of a used car should know before pay the VW Tiguan tsi price; the hydraulic clutches constituted by two rotating crowns (pump and turbine) that have a geometric semitoroid shape and are provided with flat partitions, called vanes. One of them, called a conductor rotor, is connected to the motor shaft by means of screws and constitutes the centrifugal pump; the other, attached to the primary of the gearbox with free rotation on the steering wheel, constitutes the turbine or dragged crown. Both crowns are housed in a waterproof case and are separated by a small space so that friction does not occur in between.
