The main purpose of car transmission system is to transfer/transmit the toque and the power from the engine to the wheels. The engine of the vehicle is limited to the amount of power which can be produced, because the engine is able to work only within a certain number of revolutions per minute (RPM). There are several types of vehicle transmission systems which are used these days, like: manual, automatic and CVT transmission.
Manual transmission gives allows drivers to manually change gears. The transmission input shaft is connected to the engine crankshaft, transmitting the power through the gears to the output shaft, which in turn is connected to the wheels by the drive shaft. However, it has been stated that cars with manual transmission are more prone to defects. So, finding a reputable transmission service Melbourne workshop is recommended.
Continuously Variable Transmission (CVT) is very simple transmission system which is gaining popularity these days. This system consists of two V shaped pulleys – one is fixed and the other is in two sections. The first of the two sections is fixed and the other is moved by a hydraulic pressure on the shaft. A chain, or a V belt is placed between the pulleys, which with the help of the moving pulley provides the varying gear ratios.
Out of all transmission systems available, automatic transmission is the most popular vehicle transmission system in Australia. You just need to select “drive” within the gear level and by gently pressing the accelerator, the car will run smoothly. In order to achieve this, the automatic transmission combines three different systems: a torque converter, a hydraulic control system and one or two sets of planetary gears.
The torque fluid converter contains three parts:
- The first part is the impeller, which is bottled to the engine crankshaft through the flywheel.
- The second part is attached to the transmission input shaft and has the same shape as the impeller.
- The third part is the stator, placed between the turbine and the impeller. It has one way clutch and vanes, so it can only turn in one direction.
The main difference between the manual and the automatic transmission is that the torque converter in the automatic transmission can multiply the engine power. The transmission input shaft can go faster than the engine speed by using a stator to deflect oil from the impeller in the turbine vanes and back to the impeller vanes. The automatic transmission also uses a planetary gear sets in order to change the gear ratios. This gear set at the centre, has a sun gear, several rotating gears placed on a carrier around the sun gear called planet gear, and an outer ring gear known as the annulus. By holding some gears stationary and rotating the others, the automatic transmission performs different ratios.
Automatic transmission cars are easier to maneuver than the ones with a manual system, simply because the automatic transmission does all the work by changing gears depending on how the car is driven. Regardless of the type of transmission, always take your car to a professional transmission service Melbourne workshop in order to check if everything is running smoothly. As soon as you notice that something is not right, take your car to a reliable transmission service Melbourne workshop for a thorough inspection. A professional transmission service Melbourne technician will best fix the problem. Do not try to repair transmission on your own if you don’t have the skills or knowledge, because you can only make problem worse. Instead, entrust your vehicle to a reputable car repair and transmission service Melbourne shop.
