However, it’s not a single clutch but two separate clutches operating independently, controlled by a sophisticated system called mechatronics, which includes valves and sensors.\u003c\/p\u003e\n\u003cp\u003eThe clutches are linked to two shafts:\u003c\/p\u003e\n\u003cp\u003eShaft K1: Handles odd-numbered gears (1, 3, 5, 7).\u003cbr\u003eShaft K2: Handles even-numbered gears (2, 4, 6).\u003cbr\u003eIn neutral gear, the clutches do not transmit torque. When the driver selects first gear and releases the brake pedal, the mechatronics system progressively increases oil pressure on the first clutch (K1) to start the car. Similarly, when shifting to second gear, the system reduces the pressure on K1 and increases the pressure on the second clutch (K2), completing the shift in 400-1000 ms. The oil pressure ensures a smooth transition between gears.\u003c\/p\u003e\n\u003cp\u003eThe Issue with Enhanced Engines and Torque Slip\u003cbr\u003eUnder factory conditions, the gearbox operates with oil pressures between 10 and 12 bar, sufficient for standard torque loads. However, with upgraded engines producing higher torque, the oil pressure is not automatically increased to handle the extra load. This mismatch leads to clutch slip.\u003c\/p\u003e\n\u003cp\u003eWhat is clutch slip?\u003cbr\u003eWhen the engine is running at, for example, 6,000 RPM, but only 5,000 RPM is transmitted to the gearbox, this is slip. Since the clutch operates through friction, slip causes a significant increase in temperature between the friction materials, resulting in overheating, deformation, and ultimately failure.\u003c\/p\u003e\n\u003cp\u003eEven minor slip (2-4%), which the driver may not notice, can wear down the friction materials, clogging filters and valves in the mechatronics system. Over time, this leads to malfunctions and eventual system failure.\u003c\/p\u003e\n\u003cp\u003eFriction and Torque Transfer\u003cbr\u003eFriction is a force that resists motion between two surfaces in contact. There are two types of friction relevant to clutches:\u003c\/p\u003e\n\u003cp\u003eStatic friction: Prevents movement when the clutch is engaged correctly (no slip).\u003cbr\u003eSliding friction: Occurs when there is slippage, leading to undesirable outcomes.\u003cbr\u003eTo prevent clutch slip:\u003c\/p\u003e\n\u003cp\u003eIncrease contact surface area: Achieved by adding more friction and steel plates (+2 pieces).\u003cbr\u003eEnhance the coefficient of friction: Using steel plates with greater roughness improves grip.\u003cbr\u003eBoost oil pressure: For performance applications, raising the oil pressure to 18 bar via a gearbox management remap (mechatronics) is essential.\u003cbr\u003eUpgraded Clutches for Performance\u003cbr\u003eEnhanced clutches address the first two factors by providing a larger surface area and a higher coefficient of friction. Adjusting oil pressure ensures better torque management and durability under high loads.\u003c\/p\u003e\n\u003cp\u003eFor remapping or further guidance on optimizing your DSG gearbox for your needs, feel free to contact our company.\u003c\/p\u003e\n\u003cp\u003e* Tolerance values : 1.7 - 2 mm\u003c\/p\u003e\n\u003cp\u003e** Engineer is responsible to measure the tolerances, clutch pack not covered by warranty.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"RTMG Performance","offers":[{"title":"Default Title","offer_id":50753566900551,"sku":null,"price":880.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/9430\/0999\/files\/CN4L2537.jpg?v=1736268164","url":"https:\/\/jdmpower.it\/products\/upgraded-clutch-pack-for-dsg-dq381-stock-clutches-stage-1-850nm","provider":"JDM Power","version":"1.0","type":"link"}
