The main disadvantage of automatic clutches is the lack of fun in driving a car. So the advantages are more than the disadvantages.
Automatic clutch advantages:
1. After liberating the left foot to install the automatic clutch, you no longer need to step on the clutch. The separation and combination of the clutch is completely controlled by the microcomputer, liberating the left foot, greatly reducing the driving difficulty and achieving easy driving.
2, shifting is easy and free to change gears easily, the vehicle with automatic clutch installed, just shifting can be operated very simple, no need to consider the problem of clutch separation.
3, traffic jams do not have to be afraid to open the manual car, the most troublesome thing is to encounter traffic jams, the car has to go a little bit forward, the clutch should step on one foot. With the automatic clutch installed, the traffic jam is no longer afraid, you can enjoy the fun of the automatic clutch, listen to the CD and let others worry.
4, start, brake does not turn off the automatic clutch has a flameout protection function, will not stall in any gear brakes, parking
5, when you start on the uphill slope, do not pull the car uphill, just pull up the handbrake, add a little throttle, feel the car has the power to move forward, you can release the handbrake
6. The automatic clutch is installed to maintain the fuel-saving characteristics. The clutch is precisely controlled by the microcomputer according to the data such as the speed of the vehicle and the throttle, so it is 5% more fuel efficient than the general manual vehicle.
7. Experience the driving pleasure of the hand-in-one. After the clutch is installed, the manual and automatic can be switched freely. When the automatic clutch system switch is turned off, the clutching mode can be restored, and the driving pleasure of “hand-in-one” can be realized.
8. Electronic trainer function The automatic clutch has LED gear position display and voice prompt function. By calculating the best matching parameters of gear position and vehicle speed during driving, the voice actively prompts the driver to add and subtract gears, just like asking a coach to correct driving. habit. This reduces the wear and fuel consumption caused by the high speed of the car.
Automatic clutch disadvantages:
Intensifying the wear of the clutch friction plate, the electronically controlled clutch has no way to identify and achieve the "half-clutch" commonly used by the manual transmission. If the manual transmission requires low speed, especially the slower speed of the reverse, the owner will step on the clutch pedal. The "semi-combination" of the control clutch friction plate is used to reduce the vehicle speed, but the electronically controlled clutch can only increase the drag resistance to achieve the purpose of deceleration by stepping on the brake when the friction plate is "fully integrated", which is undoubtedly increased. The load on the friction lining increases wear and tear and shortens clutch life.
Automatic clutch, which is controlled by the control unit (ECU), is an important step in shifting the manual transmission: the disconnection and engagement of the clutch can be done automatically and in a timely manner. Automatic clutches have been used in some cars to simplify the driver's handling.
The hydraulic automatic clutch adds an electronic control unit (ECU) and a hydraulic actuator system to the diaphragm clutch that is common under the eyes. The pedal-operated clutch cylinder piston is changed by the switching device to control the electric oil pump to operate the clutch cylinder piston. The Transmission Control Unit (ECU) is integrated with the Engine Control Unit (ECU).
According to sensor feedback information such as accelerator pedal, transmission gear position, transmission input/output shaft speed, engine speed, throttle opening, etc., the optimal engagement time and speed of the clutch are calculated.
The actuator of the automatic clutch is composed of an electric oil pump, a solenoid valve and a clutch cylinder. When the ECU issues a command to drive the electric oil pump, the high-pressure oil generated by the electric oil pump is sent to the clutch cylinder through the solenoid valve. The ECU controls the amount of current of the solenoid valve to control the flow of the oil and the passage of the oil, thereby realizing the movement of the clutch cylinder piston, thereby completing the clutch operation during starting and shifting of the vehicle.
Compared with automatic transmission (AT) and continuously variable transmission (CVT) vehicles, ECUs with automatic clutch devices have advantages in terms of operating economy because their transmissions are also manual transmissions, resulting in lower fuel consumption and manufacturing costs. Below AT and CVT. Of course, the convenience of car handling will also be inferior to AT and CVT, after all, it is equipped with a manual transmission, still need to manually shift gears.
