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

Kia K3 new energy hybrid vehicle introduce

The Kia K3 PHEV has been launched at the Chengdu Auto Show, with two models priced at 166800 yuan and 175800 yuan respectively after subsidies. As a pure electric plug-in hybrid model with a range of up to 80 kilometers, the arrival of the Kia K3 PHEV not only expands Kia's new energy product line, but also brings considerable pressure to several competitors. As one of the few compact plug-in hybrid products in the domestic market, the Kia K3 PHEV is a joint venture, The car is not only equipped with a power battery pack with a capacity of 12.9kWh, which enables its pure electric range to reach 80km, but also is equipped with a Kappa 1.6 GDi engine with a thermal efficiency of up to 40%, which is integrated with a long endurance electric drive system, resulting in a comprehensive fuel consumption of as low as 1L/100km. This also means that when the K3 PHEV is in a full fuel and full charge state, the car's range can reach 1080 kilometers
