Popular Types Of Gear Box In Cars In Nigeria
- Manual Transmission Or Gearbox
A lot of cars use a manual transmission, this is because it is less expensive and allows the driver to manage the car as he pleases. A manual gearbox has a driver-operated clutch which, with the aid of a foot pedal and a hand lever with which the driver can alternate the speed and torque coming from the engine. There is also a gear selector or lever, with which the driver can select the gear he/she wants to use.
- Automatic Transmission Or Gearbox
Unlike the manual transmission, the automatic transmission comes designed with an accelerator that the driver can press or depress. Here, the driver does not need to manually shift between gears, the car changes speed and torque automatically. All you need to be concerned about is the general car movement – forward or reverse.
- Continuously Variable Transmission(CVT) Or Gearbox
CVT is a type of automatic transmission, however, its internal design is different from automatic transmission/gearbox vehicles. Normally, an automatic gearbox changes gear ratios by using gears fitted together. However, in CVT, the gears are connected by using pulleys and belts. In order to change gear ratios in a CVT gearbox, happens by shifting the cheek pulleys on the secondary and primary axes. The most important advantage of a CVT gearbox over manual or automatic is that it operates smoothly without delay because you don’t need to shift gears.
- Dual-Clutch Automatic Transmission
Drivers who love dynamic acceleration and enjoy a sense of luxury when driving will prefer cars with dual-clutch acceleration. This is because they can choose to shift gears themselves or allow the gears to shift automatically. a dual-clutch automatic gearbox can be considered as an automatic type that owns two separate clutches.
