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

Volkswagen Weilan New Energy introduce

In terms of interior design, both Volvo from Scandinavia and Volkswagen from Germany are based on simplicity. The Volvo V60 is designed with a simple yet luxurious feel, while the Volkswagen NIO maintains Volkswagen's stable T-shaped layout. It is worth mentioning that the biggest highlight of the all-new B8 in terms of interior design comes from the integrated front air outlet design, which is not a big change, but very clever. In terms of seats, The sports seat configuration of the Volvo V60 is obviously higher, with electric adjustment for both the driver and passenger seats, as well as seat memory function for the driver's seat. In contrast, the Volkswagen NIO has more options for seat adjustment. The electric backrest adjustment for the driver's seat allows for manual adjustment of the front and rear height of the seat. In addition, the front seats also have manually adjustable leg rests and headrests that can be adjusted up and down in four ways, although the configuration is not as good as the V60, However, it can provide a more comfortable sitting position. As a station wagon, storage space is equally important. In this regard, both models have their own advantages. Firstly, in terms of storage compartment settings, the Volkswagen Weilan has a more diverse storage compartment compared to the Volvo V60; In addition, in terms of practicality, the Volkswagen NIO also has advantages. Taking the storage compartment next to the rear door as an example, the Volkswagen NIO can easily accommodate two bottles of mineral water, while the V60 looks somewhat impractical; However, the advantages of V60 come from the design of some storage compartments, such as the layered design of the glove box and the multiple folding designs of the rear center armrest, which enhance the practicality of these two parts through design
