What is the automatic transmission of senya s80?

Senya S80 automatic transmission is a 4-speed automatic transmission.

Like M80, Xinya S80 has two engines, 1.3L/ 1.5, both of which originated from the technology provided by Daihatsu and FAW during the cooperation period. The specifications are good, and the DVVT dual variable valve timing (equivalent to Toyota's VTT-i technology). 1.5L engine has a maximum power of 80kW/6000rpm and a maximum torque of 14 1Nm/4400rpm, which is the leading level in the same displacement.

1, working principle of automatic transmission

The automatic transmission automatically shifts up and down according to factors such as vehicle speed, engine speed and power load, which is convenient to use and does not require the driver to operate the clutch to shift gears. Especially when driving on busy urban roads, automatic transmission shows good convenience.

Automatic transmission is much more complicated than manual transmission, and there are many differences, but the biggest difference lies in manipulation. The manual transmission is controlled by the driver, and the upshift or downshift is manually operated, while the automatic transmission is automatically controlled by the machine and shifted by the hydraulic control device.

2. Composition of automatic transmission

The core control device of automatic transmission is hydraulic control device, which consists of oil pump, valve body, clutch, brake and liquid channel connecting all these components. The key component is the valve body, so it is the control center of the automatic transmission.

The function of the valve body is to control the oil pressure output by the oil pump to each actuator according to the load of the engine and chassis transmission system (throttle opening and output shaft speed), thus controlling the hydraulic torque converter, controlling the combination and separation of each clutch and brake, and realizing automatic gear shifting.

On the whole, the automatic gearbox of this car is still very good. This gearbox is powerful and has no sense of frustration when shifting gears. The most important thing is that the failure rate of this gearbox is very low.
