Electrohydraulic control system АТ, - the general information, appointment of basic elementsThe structure of electrohydraulic control system АТ includes various gauges and switches, the electronic block of management (TCM), клапанная assemblage and the complete set of electromagnetic switches.
The system exercises administration of gear change АТ, hydrotransformer blocking, муфтой maintenance of a mode of braking with the engine, pressure in the basic highway, муфтой managements of a back drive. In other words, system, analyzing the information arriving from gauges, traces changes of parametres of movement and gives out corresponding commands on six electromagnetic valves: 1, 2, 3, And, In and With.
The gauge of position throttle заслонки (TPS) serves for definition of degree of opening throttle заслонки. On the basis of arriving from TPS information TCM defines the moments of a gear change and hydrotransformer blocking, and also forms pressure in the basic highway.
The gauge of speed VSS 2 is used for management муфтой a drive of back wheels, besides, duplicates functions VSS 1 on a case of an exit of the last out of operation.
The gauge of turns of the engine serves for definition of frequency of rotation of the engine. Signals given out by the gauge are used at management of hydrotransformer blocking.
The gauge-switch of full closing throttle заслонки serves for definition of a mode of full closing throttle заслонки and is used TCM at management of functioning blocking муфты the hydrotransformer and pressure formation in the basic highway.
The switch темпостата (at a corresponding complete set of the car) is intended for inclusion/deenergizing of a control system by speed if that enters into a vehicle complete set.
The manual switch allows to forbid inclusion of 4th transfer at movement on impassability.
The switch of installation of an economic mode of movement is used on in appropriate way the equipped models for switching-off of a back drive.
The mode gauge-switch kickdown notifies TCM on full squeezing of a pedal of gas and necessity of transition to a hill-climbing gear for the purpose of short-term increase of return of the engine, for example at overtaking.
Electromagnetic valves of switching АТ
Electromagnetic valves of switching. Electromagnetic valves of switching 1 and 2 are established in клапанной to assemblage and, depending on character arriving on them from the module of management of a signal, can occupy one or the other fixed positions: It is included (ON) or It is switched off (OFF). The combination of conditions of the given electromagnetic valves defines the transfer chosen in a box. The electromagnetic valve 3 serves for management муфтой braking by the engine, also is a part клапанной of assemblage) and can be in one of two fixed conditions (ON or OFF). The electromagnetic valve And is used at management of pressure in the basic highway, established in клапанной to assemblage, is the managing director оп to the relation to valves of updating and adjustment of pressure by means of given valve TCM forms pressure in the basic highway, most effectively answering to current inquiries of the power unit. The electromagnetic valve In allows TCM to exercise administration of functioning blocking муфты the hydrotransformer.
The electromagnetic valve of management of functioning муфты inclusions of a back drive
The electromagnetic valve With is established in клапанной to assemblage and, on in appropriate way the equipped models, used TCM at management of functioning муфты inclusions of a back drive. The means of given valve TCM exercise administration of functioning of the distributive valve forming pressure in бустере муфты of a back drive.
TCM. On the basis of the analysis of signals arriving from various gauges the block of management of transmission defines traffic conditions of a vehicle and develops corresponding commands on management of transmission switchings.
The indicator a lamp of a mode of functioning of transmission. Control system АТ is allocated by function of an automatic choice of one of two modes of movement: the normal mode used at usual service conditions and a mode of raised selection of capacity of the engine. Last mode is used at movement uphill, and also joins at sharp squeezing of a pedal of gas. Modes of functioning of the indicator are shown in the table presented more low.
