Automatic transmission of AF 14/20
The block diagram of management of an automatic transmission of AF14/20 with a control system of the Motronic engine
Four-stage automatic transmission with electronic management I eat consists of the hydrotransformer, two epitsiklichesky tooth gearings and hydraulically operated coupling and brakes.
The torque from the engine to a transmission is transferred through a gidrotransfor the motor which carries out function of liquid coupling and operates as automatic coupling, also provides torque transfer at acceleration.
Liquid in an automatic transmission is cooled with a radiator of transmission liquid which is established near a big radiator.
Electric management of switching I eat transfers will involve the mechanism of blocking of gear wheels of the third and fourth transfer and carries out a choice from several modes and подрежимов movements depending on road conditions and at will of the driver.
Gear shifting is made by the electronic control device (ECU) on the basis of information from sensors of temperature of transmission liquid, speed of rotation of entrance and target shaft of a transmission, temperatures of cooling liquid, the provision of a pedal of an accelerator etc. and changes depending on the set mode of movement (see fig. The management block diagram автоматичес which AF14/20 transmission with a control system of the Motronic engine). The ECU block is located behind a ware box or behind the lateral panel of furnish in deepening for feet of the driver.
The ECU block makes management of an automatic transmission of four electromagnetic blocks which, regulating pressure of liquid, a rekey ют transfers (electromagnetic blocks 1 and 2), or operate coupling гидротран a sformator (the electromagnetic block 3), or regulate pressure of liquid depending on the provision of a butterfly valve (the electromagnetic block 4).
For smooth gear shifting, during switching, the ECU block reduces a corner of an advancing of ignition and switches off the conditioner. In the ECU block there is a function of self-diagnostics which in the presence of malfunctions in system includes a control bulb.
At installation of the lever of the selector in situation D use of the following подрежимов is possible."Economic" we will cut joins at engine start. Thus on a combination of devices the control lamp which then is switched off lights up. On it подрежиме the transmission uses all four transfers forward, including accelerating fourth transfer. Gear shifting is made for ensuring smoothness of movement on low turns of the engine. "Sports" we will cut joins after pressing of the button S located in the top part of the lever of the selector. The control lamp on a combination of devices thus lights up. In a mode S электричес Kim is blocked by a way inclusion of the fourth transfer, and gear shifting occurs at higher turns of the engine. For mode switching off "sports" repeatedly press the button or switch off and repeatedly include ignition, or make active self-diagnostics system, or be switched in we will cut "winter".
"Winter" we will cut joins in button pressing with a snowflake symbol, located in the basis of the lever of the selector. Podrezhim "winter" blocks inclusion of the first and second transfer in order that the car could get under way smoothly from a place on the third transfer on the slippery road. For transition to подрежиму "economic" repeatedly press the button or move the selector lever to other situation, or switch off and repeatedly include ignition, or hold a pedal of an accelerator pressed against the stop during more than 2 seconds, or make active self-diagnostics system, or increase speed of the car to 80 km/h.The automatic transmission and the control unit is very difficult units, but at the correct operation service life of a transmission will be long. Repair of an automatic transmission cannot make even on the majority of Opel service stations, however, using the special equipment, it is possible продиагностировать electric system of the control unit.
On models with the XEV X20 engine the upgraded ECU block which prevents mode D switching in a mode 3 for the speed over 194 km/h is established.
