Honda Hr-v

[INCINERATOR 0]

Колата е с CVT скоротна кутия и по VIN излиза, че е 4х4. При потегляне се чува шум и задницата подскача - по-красноречиво не мога да го опиша Някой казват, че е от скоростната кутия варианти два:1) Приплъзва заради НЕ смяна на маслото на кутията2) Износен "съединител"Други казват, че е от диференциал.Според вас от какво може да е?Някой може ли да ми обясни принципът на действие на 4х4-то му.Благодаря за вниманието.

Никои ли не знае поне начинът на действие на 4х4-то...

Смятам че това изчерпва твоя въпрос - дано разбираш английски! В момента нямам време за превод.

 

Honda

CR-V, HR-V 1996-... - Automatic all wheel drive. Honda's Real Time Four Wheel Drive System. Normally front wheel drive vehicle. Torque transfer to rear axle via multi-plate clutch. Dual pump system is used to apply pressure to the clutch. It also disengages the clutch when braking to allow ABS work smoothly.

How Honda's Dual Pump 4WD works

 

For most of the time, only the HR-V’s front wheels are driven; it’s only when they begin to lose grip that the Dual Pump system starts to send power to the rear wheels. This is achieved by a hydraulic torque-split system, consisting of a conventional front-wheel drive arrangement, complete with transfer case, a propeller shaft running the length of the vehicle and a Dual Pump system integrated with the rear differential. This is the heart of the system and comprises two hydraulic pumps, one driven by the front wheels via the prop shaft, the other by the rear wheels via the rear differential.

During normal levels of grip the front and rear wheels, and their respective pumps, turn at the same speed; hydraulic pressure circulates between the two pumps, but no pressure is generated. If the front wheels begin to lose traction and start to spin faster than those at the rear, the two pumps turn at different rates; hydraulic pressure proportional to the difference in their speeds is generated, which in turn opens a valve body and activates a mechanical, multi-plate clutch.

This clutch then connects the front prop shaft to the rear diff, which feeds precisely the correct amount of torque to the rear wheels to re-establish overall traction. The more the front wheels slip, the greater the torque fed to the rear wheels.

The Dual Pump arrangement weighs less than a conventional four-wheel drive system and demands little maintenance – just a fluid change at 72,000 miles and thereafter every 36,000 miles. Further advantage of this design is that it automatically disengages under braking, thereby allowing the ABS to operate.

Значи проблемът може да е изцяло от 4х4-то. Благодаря за информацията.
