Audi 0B5 DCT clutch assembly for export — TRANSFENG Mingfeng stock

Specifications

Transmission type
Seven-speed dual-clutch gearbox — full synchromesh, seven-speed transmission, electro-hydraulically controlled (Audi eSelf Study Program 950143)
Designations
Manufacturer: DL501-7Q · Service: 0B5 · Distribution: S tronic (Audi eSelf Study Program 950143)
Layout
Two sub-gearboxes. Clutch K1 drives input shaft 1 for the odd-numbered gears; clutch K2 drives the hollow input shaft 2 for the even-numbered gears and reverse. Both sub-gearboxes feed a common output shaft.
Power path
Drive goes from the drive plate to the dual-mass flywheel and then to the hydraulically controlled dual clutch. Output goes straight to the centre differential — roughly 60% of torque to the rear axle and roughly 40% to the spur pinion for the front axle.
quattro centre differential
Crown-gear limited-slip centre differential: the asymmetric basic torque split comes from the approximately 40:60 crown-gear tooth ratio (approximately 40% front and 60% rear)
Dynamic torque split
Torque vectoring works with the crown-gear differential and can vary the split instantly — up to 70% of torque to the front axle and up to 85% to the rear. It cannot be deactivated by the driver.
Output connection
Splined output shaft: the prop shaft slides into position and is secured by an integral spring sleeve and locking clamp — approximately 1.3 lb (0.6 kg) lighter than a flanged connection and faster to assemble and service
Lubrication
Two circuits: ATF for the clutch and transmission control (with a pressure filter) and a separate manual gearbox oil (MTF) for the gear set and mechanicals. MTF temperature is monitored by the transmission control unit.
Parking lock
Electro-hydraulic parking lock with a mechanical emergency release
Shift quality
Overlapping gearshift with engine torque intervention: the gear change is completed within a few hundredths of a second with no interruption in tractive power
Final drive options referenced with the unit
0BC (standard rear axle final drive) and 0BF (sport differential) — on 0BC vehicles torque vectoring acts on the front and rear axles, on 0BF vehicles on the front axle only

Common applications

  • Audi models with the longitudinal quattro driveline — the 0B5 is Audi's longitudinal wet-clutch S tronic (Audi eSelf Study Program 950143)
  • Audi S and RS models — Audi's own Self Study Program describes the design characteristics and strength of the 0B5 as well suited to many S and RS Audi models
  • Vehicles with the crown-gear centre differential and torque vectoring — final drive 0BC (standard) or 0BF (sport differential)

Fitment is listed for reference only — always confirm by transmission code or by sending us two or three photos of the unit before ordering.
