Magnetventiilile läheb 2 juhet - üks on miinus, teine pluss (see + juhe käib läbi tempi anduri).
Skeem:
Seal külljes on ka veel survelüliti, mis ei reguleeri ventiili tööd, vaid kui surve läheb liiga suureks, siis saadab ta uuesti ringlusele.
Tsiteeri:
The pressure switch (arrowed), is screwed into the rear of the control valve block, controls the hydraulic system pressure between control valve and transfer box.
No sellesmõttes jah takisti, et kui vahekastis õli liiga kuum, siis temp andur ei ühenda juhtmeid ära, vaid tekib suur takistus. See andur on ju ühekordne, seega ei ole võimalust, et ta viskaks lampi maanteel järelt ära.
Tsiteeri:
Connect a multimeter, set to the Ohms scale (x1), and measure the resistance across the plug towards the temperature sensor. The reading should be short circuit. If open circuit investigate, and if the wiring is intact the sensor has probably been operated through overheating of the TXB. This is a one shot sensor and once operated has to be replaced. (approx. £62).
ABS annab jah rataste pöörlemiskiiruse infot ajule. Seega ventiilile tuleb ajust signaal (see + juhe, mis läbi nr 19 kaitsme läbi käib ning läbi temp anduri läheb). Selle lükkab nt pidurdamisel ju tagant ära.
Tsiteeri:
With the engine running, the solenoid valve (3) is operated all the time and 4WD is engaged. The only exception is when the brakes are applied at speeds above 25 km/h (16 MPH). When the brakes are released the solenoid re-operates and 4WD is re-engaged, regardless of speed.
See 100% jutt tundub jah kahtlane. Aga põhimõte sama.
Tsiteeri:
The Viscous Coupling is the section of the transfer box that determines how much of the driving force goes to the rear axle and how much is sent to the front wheels i.e. this unit is the sole operator of the power split in the Cavalier or Calibra 4WD system.
Tsiteeri:
Under normal conditions, the drive is split so that 75% of the power is driven to the front wheels and 25% is driven to the rear wheels. The secret of the Viscous Coupling is based in the silicone fluid it contains.
When driving normally, the difference in RPM (rotational speed) of the front wheels and the rear wheels is minimal. That is they are travelling at virtually identical speeds. This also means that the internal discs and the external discs are also turning at the same speed as these are connected to the corresponding axles.
If the speed of one set of wheels were to be more than the other, for example the front wheels lose grip so spin faster than the rear, then the difference in speeds of the corresponding disc's in the Viscous Coupling will also increase proportionally. In this case the inner discs would spin faster than the rest as these are connected to the front wheels.
This difference in speed of the discs means that the silicone fluid can no longer flow freely between the plates. This would cause a "cutting" action within the silicone fluid as it is sliced between the slits of the interior discs and the holes of the exterior discs resulting in the silicone fluid heating up instantly.
The properties of the silicone fluid are such that as the temperature increases so does the viscosity or thickness of the fluid. This results in the previously freely spinning plates to become increasingly locked together allowing more of the power to be transferred to the rear axle via the external discs.
