transmission housing introduce

Transmission housing: The transmission housing and cover are used to install the transmission mechanism, shifting device, and some control mechanisms, while storing lubricating oil. In order to reduce the weight of the car, for sedans, the transmission housing and cover are often made of aluminum alloy or magnesium alloy. The transmission housing and cover of medium and heavy vehicles are generally made of cast iron to ensure their strength requirements. The material of the transmission housing is gray cast iron, commonly used as HT200. The transmission housing is the basic component, Used for installing and supporting all parts of the gearbox and storing lubricating oil. It has precise boring holes for installing bearings. The gearbox bears variable loads, so the housing should have sufficient stiffness, with reinforced inner walls and complex shapes, mostly made of castings (made of gray cast iron, commonly HT200). For ease of installation, the transmission and control parts are often made into split sections, and the box cover is connected to the housing by bolts and reliably positioned. There are oil filling and drainage ports, and oil level inspection dipstick ports on the housing, Heat dissipation should also be considered)

Common faults of automatic transmissions include:

Common faults of automatic transmissions include: 1. Oil leakage: Oil seeps out from the gearbox housing or oil pan due to aging seals, poor sealing, and poor manufacturing processes, resulting in sand holes in the housing; 2. Engine shutdown when shifting into D or R gear: The engine shutdown when shifting into D or R gear may be due to damage to the locking solenoid valve; 3. Locked gear: The input and output signals of the gearbox are incorrect or the circuit components themselves have poor wiring; 4. No response when shifting: Shift into D or R gear, then release the brake and the vehicle will not move. This situation is often caused by damage to the input shaft or reverse clutch; 5. During driving, the vehicle may experience gear shifting shock and jerking, which may be caused by dirty transmission oil, resulting in valve body jamming; 6. Transmission slippage and weak acceleration: When the car is driving, there is a sound of the engine idling due to the acceleration of the fuel gate. This phenomenon is mostly caused by burnt clutch plates

audi a6 introduce

The Audi A6L is a series of cars developed by FAW Volkswagen Audi based on the new A6 in Germany. It is a successor to the A6 and was launched on June 16, 2005 In June 2012, Audi's new generation A6L was launched, equipped with 35 TFSI power, and its appearance seemed a bit like the all-new A4L version. On January 23, 2014, the new generation A6L was launched, priced at 38300-742600 yuan, which is almost no different from the 2012 model. For a long time, the official image of Audi A6 has been deeply rooted in people's hearts, and even in Europe and America, A6 has also been favored by government agencies and business people. The 09 A6L has made some modifications in terms of appearance, The biggest change is the addition of LED daytime running lights to the headlights, and the use of LED tail lights with a new arrow shaped design. In March 2012, the younger generation of Audi A6L was launched in China
