What does a secondary clutch do?

What does a secondary clutch do?

The secondary clutch is mounted to the input shaft of the transmission, transaxle, or the like. In modern CVT systems such as those used in recreational vehicles, the secondary clutch has two functions: as a “slave” to the primary clutch and to provide a torque sensing element.

Which clutch is primary and secondary?

The primary has what is called buttons, these ride against towers that allow the sheave to open and close. The Secondary has what is called a roller, and it rides up and down on the ramp of the secondary clutch.

How do I know if my secondary clutch is bad?

However, the most common symptoms are as follows:

  1. Noise from the clutch.
  2. Engine is hard to crank and bogs down.
  3. Sled loses its power.
  4. Increased fuel consumption.
  5. Poor backshift.
  6. Signs of wear on the clutch.

At what RPM does a snowmobile clutch engage?

Anywhere from 3,500 to 4,500 rpm is acceptable. Any lower than that and the sled is going to bog off the line and any higher than that and the clutch engagement is difficult to manage while trail riding.

Does a CVT gearbox have a clutch?

The CVT gearbox has been used in various different cars, but you’ll usually find it fitted to a small car. In many ways a CVT gearbox is similar to a regular auto. For starters, there is no clutch pedal in a CVT-equipped car, so you can drive it on an automatic-only UK driving licence.

What does a primary clutch spring do?

The job of the primary spring is to keep the clutch from engaging(making the sled move forward) until the motor has reached a specific RPM.

How long does a Rzr clutch last?

We have seen failures happen at 1000 miles, and even have clutches last over 3000-4000 miles. The best thing you can do is install a set of our performance rollers ASAP with the least amount of miles possible. Most will install our clutch kit at the same time which also saves on belt life/clutch wear.

What does primary clutch spring do?

The primary spring also controls peak RPM to an extent. The primary spring controls the downshift in the primary clutch, the force of the spring pushes the moveable out(towards the left side of the sled) when the clutch is downshifting, say when you let off the throttle.

How does the primary and secondary clutch work?

Helixes and secondary springs are calibrated to balance the pull from the belt created by engine torque plus the up shift force generated by the primary clutch at a point where the engine will shift out at a constant rpm. The secondary clutch works off a torque feedback mechanism that senses load at the track through the chain case.

Which is the secondary clutch in a CVT system?

The secondary clutch will always be bolted to the transmission input, as it is the last part of the CVT system. It is also called the driven clutch because it is driven forward by the belt. 3. Belt. The belt is the link between the two clutches.

Which is less contact patch area primary or secondary clutch?

The most important data in figure #1 is that the primary clutch has less contact patch area then the secondary clutch until the 1:1 shift ratio.

What are the total angles of the primary clutch?

(click for…) As we have shown in the past, most primary clutch sheave angles are between 24-28 total degrees depending on the manufacturer. In the secondary clutch total sheave angles as low as 19 degrees have been measured. Why don’t some secondary sheave angles match the primary clutch? There may be good reasons.

What kind of clutch does a golf cart have?

Golf cart clutches or the CVT (Continuously Variable Transmission) is comprised of two different clutches connected together by a thick drive belt. The components are the drive (primary) clutch and the driven (secondary) clutch).

The most important data in figure #1 is that the primary clutch has less contact patch area then the secondary clutch until the 1:1 shift ratio.
