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

BAIC Weiwang 407EV New Energy introduce

In terms of appearance, although this car is a pure electric box truck, its appearance tends to be designed in the style of a concept car. Because it does not need to collide with the wind and dissipate heat like an oil burning motor vehicle, the front face of the car only uses a banner style black paint decorative panel, which is integrated with daytime running lights, making the entire truck look full of texture. Although the rear end is relatively square, the rich line design gives the rear end a certain sense of hierarchy, The rectangular tail lights with a vertical bar style are also very stylish, and the lighting effect is stunning. According to the vehicle positioning, the Weiwang 407EV can not only enter through the rear door in crowded streets, but also through the sliding door on the right side. The tail door adopts a 4/6 ratio split design, making it more convenient and flexible to get off and transport goods. The entire trunk volume of the car is 4.5 cubic meters, and the load capacity can reach 810kg
