Lotus Clutch Fitting

The clutch in your Lotus connects and disconnects the engine from the gearbox (transmission) allowing smooth gearchange and control of the Lotus engine power.

A clutch plate (driven plate) is coated on both sides with a hard wearing high friction material. This is situated between the engine flywheel and a spring loaded pressure plate. The spring/pressure can be released by depressing the clutch pedal.

While driving, the whole clutch assembly can be turning at very high speeds. To allow a non rotating clutch pedal to control the rotating clutch assembly a clutch release bearing uses a fork acting on a thrust face

Lotus Clutch - Controlling Engine Torque

The clutch has to transmit the engine power to the wheels allowing the vehicle to move. The torque of the engine is transferred by the Lotus clutch system relying entirely on the contact friction between 2 faces. A slipping clutch occurs when the friction is too low (often due to clutch wear) or engine torque is too high (during rapid acceleration)

Controlling Power Transmission via The Clutch - Clutch Slip

The torque capacity (how much power can be transmitted without slipping) depends upon:

  • The Coefficient of Friction of the engaging Clutch Faces
  • Diameter of the Clutch Plate
  • The Pressure or Spring Loading

In order to use greater engine torque in high performance vehicles a multi-face clutch may be used compared to the single plate clutch system adopted on most Lotus cars.

How a Car Clutch Works with Normal Manual Driving

A car clutch is engaged/disengaged using the left most "clutch" pedal.
The clutch pedal is depressed to disengage the engine from the gearbox and drive train while changing gears. Once the gear is selected, the clutch pedal is released and the engine is once-again linked via the drive train
The clutch operation can be actuated by:

  • A Mechanical Linkage
    The clutch pedal is connected directly to the clutch assembly via a mechanical linkage such as cable or chain.
  • A Hydraulic Clutch
    Depressing the clutch pedal increases pressure in a hydraulic piston coupled to the clutch pedal. The increased pressure is transferred to a secondary piston that operates a lever to engage-disengage the clutch plates
  • An electronic clutch - Clutch by Wire
    Sensors detect the position of the clutch pedal electronically and interpret the position using an Electronic Control Unit (ECU) that computes the best way to operate the clutch based upon information relayed from other sensors indicating driving speed, engine speed and so on. The ECU relays information to a servo unit to actuate clutch operation.
