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

Ralink introduce

The Lexus is a compact sedan designed specifically for Chinese consumers based on the Toyota MC platform. It made its debut on April 18, 2014 and was officially launched in the summer of 2014. The Lexus is based on the 11th generation Corolla American version of Toyota's A-class cars. The American version, with a sharp appearance and excellent quality, has been popular in North America for many years and has long ranked first in the A-class car market in terms of sales. The Lexus inherits the champion gene of this model, With a very high quality foundation, the exterior design of the American version of the Lexus comes from the North American Raptor White Headed Sea Eagles, and the Lexus also inherits its sharp style in exterior design. This sharp appearance gives the Lexus a high degree of recognition, creating a breathtaking visual experience. The all-new Lexus is a product created on the GA-C platform under the TNGA architecture. In addition to changes in appearance, the interior, chassis handling, and safety have also been enhanced, All aspects of intelligence have been upgraded. At the 2019 Shanghai Auto Show, the all-new generation of Guangzhou Toyota's Lexus officially began pre-sales and was officially launched in Wuzhen on the evening of May 20th [3] The new car currently offers a total of 10 models equipped with two types of power: a 1.2T turbocharged engine and a 1.8L hybrid system, with a price range of 115800 to 152800 yuan
