Clutch AWD - Overview

OVERVIEW

The clutch is a conventional type, with a single stage damped driven plate and a spring clutch cover assembly which is hydraulically actuated from the clutch pedal.

The main components of the clutch are the clutch cover assembly (pressure plate), the engine flywheel and the driven plate (friction plate). Together with flywheel and driven plate, the clutch cover forms a friction system and is mounted to the flywheel by bolts in the housing.

Clutch AWD - System Operation and Component Description

System Operation

OPERATION

When the clutch pedal is not being operated, the clutch provides a friction drive between the flywheel and the clutch cover.

The contact force to produce the required friction is provided by diaphragm springs in the clutch cover assembly.

Operation of the clutch pedal produces hydraulic pressure in the clutch master cylinder which is passed via pipes to the slave cylinder. When the slave cylinder is operated, the cylinder piston moves, the pressure on the diaphragm springs is released and the contact plate can pivot on the cams, releasing the pressure on the driven plate. This removes the pressure on the clutch plate friction surface allowing the driven plate to disengage the drive between the engine crankshaft and the transmission.

Component Description

DESCRIPTION

Clutch Cover

Range Rover Evoque. Clutch

  1. Contact plate
  2. Diaphragm spring
  3. Cover
  4. Mounting holes

The clutch cover ensures that the engine torque is transferred via the driven plate to the transmission intake shaft. The contact force required for transferring engine torque is provided by a slotted diaphragm spring. The diaphragm spring allows the driver to apply less pressure on the clutch pedal due to low engaging force. A contact plate provides the friction surface for the driven plate to engage on.

The diaphragm spring is of the compressed type which is actuated by the slave cylinder. When the slave cylinder is operated, the force from the diaphragm spring is transferred through the clutch cover housing into the flywheel it is bolted to, releasing the pressure on the driven plate and disengaging the drive to the transmission.

The clutch cover contact plate is attached to the clutch housing by plate springs. Cams on the contact plate project through the openings in the housing and the outer diaphragm springs are supported on the cams. The contact plate is attached to the housing by bolts and wire rings. When the slave cylinder is operated, the pressure on the diaphragm springs is released and the contact plate can pivot on the cams, releasing the pressure on the driven plate.

Driven Plate

Range Rover Evoque. Clutch

The driven plate is the central connection element in the clutch. In combination with the clutch cover assembly, it separates and links engine and powertrain by connecting the engine crankshaft to the transmission input shaft.

The driven plate is a rigid type friction plate with a compound organic resin friction material. The splined hub is attached to the disc with four springs to damp driveline vibrations. The splined hub mates with corresponding splines on the transmission input shaft.

Dual Mass Flywheel

Range Rover Evoque. Clutch

  1. Crankshaft mounting holes
  2. Ring gear (primary side)
  3. Friction surface (secondary side)

The dual mass flywheel comprises two main components; the primary side which is attached to the engine crankshaft and the secondary side to which the clutch cover assembly is attached.

The primary side has the starter ring gear attached to its outer circumference. The ring gear is used by the starter motor to rotate the engine during engine crank at start up. The primary side is secured to the crankshaft with eight bolts. A dowel in the crankshaft flange ensures that the flywheel is correctly located.

The secondary side has the smooth friction surface on which the driven plate friction material engages. Dowels and threaded fixing holes allow for the correct alignment and attachment of the clutch cover assembly.

The primary and secondary sides are connected with long coil springs. The two sides can rotate against each other, limited by the coil springs, which absorb torque loading on clutch engagement and torsional vibrations from the engine.
