10.4. A five-step mechanical transmission

Standardly Mondeo transfers the capacity of the engine to driving wheels by means of "manually" switched five-speed transmission (МТХ-75). МТХ-75-коробка transfers is «the old acquaintance» from fund of units Ford: it, for example, use as well powerful variants Focus. Mondeo 2001 «switches and thoroughly modified variant МТХ-75 operates», certainly. It, for example, possesses.

    New external side scenes of a gear change, Target shaft of other design – the small gear wheel here is a strong component of a shaft, The case of a transmission co-ordinated with the new engine.

As before, transmission МТХ-75 works as a design from two shaft: the M letter designates "manual", Т – a transmission, Х – a forward drive, and number 75 characterises distance in millimetres between conducting and conducted shaft.

At neutral position any of driving wheels does not contact to leading or conducted shaft: any twisting moment it is not transferred to differential. Only one conic roller bearing has leading and conducted shaft from the parties of coupling and a transmission at corresponding halves of the case of a transmission. The small gear wheel of a conducted shaft is in constant gearing with a cylindrical cogwheel of differential is a detail of a conducted shaft. Transfer gear wheels – 1/3 transfer and муфта the synchronizer – 1/3 transfer settle down on the leader to a shaft. Gearing for transfers 1, 2 and reverse motion are details of a conducted shaft. Transfer gear wheels 1/2/5 and reverse motion settle down on conducted to a shaft. Gearing for 3 and 4 transfers, and also a small gear wheel of a leading shaft are details of a conducted shaft. Transfers 1–3 have double synchronisation. It consists of an internal synchronising ring, конусного rings, an external synchronising ring and the synchronizer case. The transfer wheel has конусной no surface: synchronisation is carried out by means of synchronising rings and connected by kinematic short circuit with a transfer wheel конусным a ring. Besides, also reverse motion is synchronised also.

Double synchronisation the standard for first three transfers

1 — the Transfer gear wheel,
2 — the Internal synchronising ring,
3 — Konusnoe a ring,

4 — the External synchronising ring,
5 — a synchronizer Body.

Transmission repair – at doubts a variant for мастерско

According to various variants of engines of transmission Mondeo work with different transfer numbers. According to practice, an automobile life of boxes МТХ-75 long enough. If you have considered that at you an exception of this rule it is better to go to a specialised workshop as the special tool there is used and the corresponding competence and experience are thus necessary. If is not present, here there are no bases for false shame: many workshops send transmissions subject to repair, as a rule, to their manufacturers for audit at stands or at once replace them with exchange units.

Modern design of a transmission: mechanical box МТХ-75

1 — Carter of coupling,
2 — the Leading shaft,
3 — Transmission,
4 — the Conducted shaft,

5 — the Intermediate gear wheel of reverse motion,
6 — the Case of a transmission,
7 — External switching.


So the mechanical transmission functions

Capacity of the engine is transferred through coupling to a leading shaft (an entrance shaft) mechanical transmission. On it to a shaft five gear wheels with slanting teeths (plus one gear wheel for reverse motion) settle down. All transfer gear wheels have the suitable partner on conducted to a shaft, and they are in constant contact among themselves.

Gear wheels and shaft

Until, while gear wheels will not contact with the partner, they rotate freely. As soon as the transfer joins, corresponding pair of gear wheels incorporates with each other in power short circuit. The lever of a gear change by means of тросовых draughts, "balance weights" and bars operates on a gear change plug. It connects transfer wheels power short circuit with each other by means of the mobile plug. That both wheels in the course of switching quickly and silently have found each other, synchronising rings lead this "couple" to identical frequencies of rotation: they "brake" for this purpose in a starting cone faster gear wheel until profiles of a teeth of transfer wheels will not enter into silent contact and not заскользят one in other.

Separate transfers

First three transfers translate frequency of rotation of the engine in slower. Since the fourth transfer driving wheels rotate already "faster" than the engine. Experts speak here about long transferring transmission which осознанно supports a stable twisting moment in new engines Ford. On the fifth transfer the difference between frequencies of rotation of the engine and a drive increases even more: it spares the engine, «without tightening a loop on his neck», and reduces, mainly on long distances, the fuel expense. On all forward transfers the backlash is formed by two cogwheels. Only the reverse gear uses three gear wheels. The third gear wheel named also intermediate, rotates on own to a shaft, it becomes active when for a backing it is necessary for conducted shaft to change a rotation direction.

Short way: a power stream in the first transfer.

1 — the Leading shaft,
2 — the Conducted shaft,
3 — the Small gear wheel of a conducted shaft,
4 — the Transfer gear wheel,
5 — the Synchronizer,
6 — Gearing

Change of a direction of rotation: the intermediate wheel does it possible.

1 — the Leading shaft,
2 — the Conducted shaft,
3 — the Small gear wheel of a conducted shaft,
4 — the Synchronizer, 5th transfer and a backing,
5 — the Transfer gear wheel of a backing,
6 — the Intermediate gear wheel of a backing,
7 — reverse motion Gearing.
