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

Dongfeng Xiaokang C31 introduce

The Dongfeng Xiaokang C31 is a practical micro truck model that combines strong load-bearing capacity and excellent power. "Big Power, Big Load" is also the promotional slogan tailored by Dongfeng Xiaokang. In terms of appearance, the Dongfeng Xiaokang C31 has strong originality, with a rounded front face design and two chrome plated front air grilles that perfectly match the headlights, full of affinity; In terms of body size, the Dongfeng Xiaokang C31 has obvious advantages compared to competing models, with an external length, width, and height of 4730mm, 1655mm, and 1960mm respectively, and a wheelbase of 3050mm. In addition, the C31 eliminates the second row seat space, and its cargo box length, width, and height can reach 2900mm, 1540mm, and 370mm. The ultra long cargo box size can also meet the demand for loading more and longer items; In terms of power, the Dongfeng Xiaokang C31 is equipped with two types of engines: the "DK12-05" 1.2-liter naturally aspirated engine and the "DK15-06" 1.5-liter naturally aspirated engine. The 1.5-liter engine has a maximum power of 86 kW and a maximum torque of 147.5 Nm. When paired with a 5-speed manual transmission, the comprehensive fuel consumption per 100 kilometers is only 7.5L. Its excellent fuel efficiency and strong power performance also highlight the practicality advantages of the Xiaokang C31
