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

Mercedes Benz CLK introduce

The Mercedes Benz CLK is a new model of Mercedes Benz, and the CLK class sports car will be launched with a new face on the basis of the E-Class. Its interior space is more spacious, the wind resistance coefficient is lower, and the power is stronger. The model consists of a roof, electronic stability program, lighting system, head airbag, automatic rollover guard, sports package, and model overview. Due to the extended wheelbase of the 2003 CLK sports car, it is generally longer, wider, and higher than the old version, The cabin space is also wider. The strength of the car body has increased by 40%, and the drag coefficient has been reduced to 0.28cd. The side windows adopt frameless design technology, which can fully retract the doors and side body. The safety configuration of the 2003 CLK mainly includes front and side airbags, side window airbags, pre tension seat belts, and impact force limiting devices. The interior decoration materials can be selected from wood or aluminum according to personal preferences, but all CLK instruments are wrapped in chrome alloy. The rear seats are foldable, This can increase storage space. Other standard devices include wipers with sensing system, headlight assist device, and air conditioning control device. Optional parts include automatic cruise control system, xenon headlights, and voice controlled telephone. In 2010, with the release of the new generation of E-Class sedans, Mercedes Benz launched E-Coupe, which is no longer used in CLK class sports car models
