10.7. Good alternative to a mechanical transmission – automatic box Mondeo in a combination with 2,0-litre engine Duratec-HE

The transmission having designation CD4E represents an electronic automatic 4 step transmission for front-wheel cars. Automatic transmission CD4E works together with coupling for blocking of the hydrotransformer and included pressing of the button by the accelerator. Two connected one after another of some planetary gear wheels realise corresponding transfer relations – three multidisk couplings, one multidisk brake, one brake tape and the roller mechanism of a free wheeling reproduce приводные and brake functions. The privodnoj moment passes the cascade of intermediate gear wheels before it will reach the main transfer.

Switching without rupture of traction force: the planetary mechanism

1 — the Solar gear wheel, 1-/1-transfer,
2 — Drove planetary transfer 1-/2 transfer,
3 — Koronnaja a gear wheel 1-/2 transfer,
4 — the Solar gear wheel, a back course/4 transfer, a solar gear wheel and the case of a solar gear wheel,

5 — Drove planetary transfer, a back course/4 transfer,
6 — Koronnaja a gear wheel, a back course /
4 transfer,
7 8 — Klinovoe gearing

Automatic transmission Mondeo – so is switched a transmission step

Automatic transmission Mondeo under loading changes the transfer relation – as well as all automatic transmissions – without rupture of traction force. As "coupling" the automatic machine puts in action the four-componental converter of a twisting moment with blocking coupling. The converter enters «into game» following components:

    Set of planetary gear wheels, Chain drive, Planetary transfer (the main transfer), Differential of a conic and lateral wheel.

It receives the instructions from the hydraulic mechanism with electronic control.

By means of the switching lever it is possible to operate six functions: P, R, N, D, 2, 1. Besides, the control switch of a transmission opens to you an option for accelerator "repayment". On the second and third transfer driver Mondeo with such box can use besides action of a motor brake.

Position (): In this position in a transmission there is no transfer of force. The lever of a shaft of management of a gear change which is connected to camshafts, presses a parking cam on a parking wheel to a resulted chain wheel. Thanks to it the main transfer is locked and приводные wheels "are blocked". With a view of safety always establish in parked Mondeo a lay brake.

Position (R): In this position you move with the lowered transfer relation back. Action of a motor brake in position R, however, takes place.

Position (N): as well as at position Р, in a transmission there is no transfer of forces. However the main transfer is not blocked by a parking cam – that wheels can rotate. You also can start the Mondeo at position N.

Position (D): in position D (DRIVE) during a normal mode of operation automatically there are all processes of switching (from the first before the fourth transfer) and programs (inclusion and coupling deenergizing, blocking coupling, optimisation of the expense of fuel). The fourth transfer (Overdrive) uses action of a motor brake and can be blocked on the gear change lever the control switch of a transmission. At switched off Overdrive (the TCIL-indicator burns) automatics uses action of a motor brake of the second and third transfer.

Position (2): Position 2 "blocks" 2nd step after automatic or manual switching on the lowest or higher transfer. As soon as you at a stop have preliminary established 2 transfer, you Mondeo gets under way at a step 2 – advantage on slippery roads or in the presence of ice or snow. In position 2 action of a motor brake is given to the second transfer.

Position (1): Position 1 represents the first step. To protect transmission from vyshen th frequencies of rotation, РСМ ignores at from above 48 km/h position 1. Needless to say, in position 1 influence of the motor brake moment also is given – these brakes help to protect the car at movement in mountain district.

Switching on high transfer: For management of switching processes, pressure of switching and coupling of blocking РСМ processes various signals from various gauges and personal commands of the driver.

Switching on low transfer: Under certain conditions the transmission is automatically switched to a low range (without use of the lever of a gear change). There are three categories for automatic switching on low transfers: a mode of compulsory idling, the twisting moment requirement, and also the compelled inclusions of a hill-climbing gear.

Mode of compulsory idling: Switching on low transfers to a mode of compulsory idling occurs in that case when the car in this mode manually carries out braking.

The twisting moment requirement: Switching on low transfers for observance of requirements to a twisting moment is carried out automatically during accelerations at partial loading as soon as the requirement to a twisting moment at this transfer relation will exceed the engine possibilities, the included cylinder of blocking is switched off, occasionally, to take care of additional acceleration.

Hill-climbing gear inclusion (Kickdown): Switching on low transfers for the purpose of the maximum acceleration can be caused full pressing a gas pedal – at speeds below 88 km/h on the second transfer and below 40 km/h Kickdown causes switching on the first transfer.

Principle of functioning of the control switch of a transmission and the indicator: the Accelerator can be switched off by means of the control switch of a transmission. The system again automatically includes the accelerator as soon as the engine is started or joins again the control switch of a transmission. It is visually shown on the lighted up bulb on a guard of devices.

9 — the Expert-coupling,
10 — the Gauge of frequency of rotation of a target shaft (OSS).

Repair of an automatic transmission – any work for the fan

Modern automatic transmissions overtake an appeal to reliability increase. And it it is possible to tell with good reason: as, as practice has shown, their failure, at appropriate operation, can be hardly probable caused unreasonable deterioration. In other words: on machine tools in workshops Ford occurrence of an automatic transmission – very big rarity. Naturally, there are also exceptions of this rule: when such units «badly look after». As a result of it for audit they should come back to factory.
