It’s #TechnicalThursday once again and today we have a jam packed episode. Today we speaking all things Transmissions ✨
Transmissions are machines which provide controlled and variable power and torque within a drivetrain
There are 2 types of transmissions, a Manual and an Automatic transmission
The basic composition of a transmission:
Manual- This transmission needs input from the driver in order to shift gears. These cars usually have three pedals(some drag racing gearboxes that use a hand clutch)
Automatic- this transmission is fully capable of shifting gears without any input from the driver, these cars have no clutch pedal
The basic operation of a manual gearbox: In order to change gear ratios, the clutch pedal must be fully depressed. This disengages the gearbox from the running engine and allows you to change gears manually using the shifter knob. The clutch may then be released engaging the...
Drivetrain and the motor so that the car is back in drive. Manual transmissions are more engaging with the driver and allow you to shift at optimal times depending on situation and the power/drive you need.
Basic operation of an Automatic Transmission: This transmission has a ECU which decides when the optimal time for shifting gears is. The driver does can keep their foot down on the accelerator as the transmission will handle the disengaging of the clutch as well as gear selection
Some automatic transmissions allow for the driver to control when to shift up or down by using paddles behind the wheel or by tapping the gear knob. There are currently many types of automatic gearboxes on the market I’ll give quick descriptions of them all below.
DCT: Dual-Clutch Transmission
This is a semi-automatic gearbox which uses two sets of clutches, one for even gears and one for odd gears usually a very quick shift.
CVT: Continuously Variable Transmission
This is an automatic transmission that can change seamlessly through a continuous range of gear ratios. Unlike other transmissions that provide a limited number of fixed gear ratios. CVT makes use of a belt system to range between ratios.
TCM/TCU: Transmission Control Module/Unit this is an electronic management system used in automatic transmissions. This unit can be tuned to optimise shifts by tuners as well as to decrease shifting times etc..
The world of transmissions really doesn’t end. But I think I’ve covered enough to poke your mind. And explain a couple of things
Thank you for joining us once again✨🙏🏾
