The Basics of the Car Transmission

 

The most basic knowledge of the car transmission includes knowing the parts that comprise it. It is comprised of the Main shaft, Blue gears, Small gears, and the Torque converter. The following article will explain the different parts of the car transmission and their functions. If you are unsure of any part, you can seek assistance from a mechanic. If you’re not comfortable doing any repair work yourself, hire a professional to do it for you.

Main shaft

The main shaft of a car transmission is the primary part of a vehicle’s drive train. This component extends from the front to the rear of a vehicle and is sometimes called the output shaft. The input shaft supports the front of the main shaft, which rotates at different speeds and provides the torque needed to move a car. Unlike most other car parts, the main shaft is splined, which allows the gears to move.

The main shaft of a car transmission is the gear box’s central piece, and it is the center of the vehicle’s drivetrain. Designed to transfer torque, the shaft’s gear box and other components transfer the load to the transmission. Using ASME code, transmission shafts are designed to meet specific strength requirements. As with other mechanical components, the ASME code applies equations for shafting to determine the stress and load characteristics of the drive train. For example, the shafts should be designed to resist heavy shock loads, and they should also incorporate additional stress reduction and blending radii.
Blue gears

The car’s transmission has three gears: red, blue and reverse. Each gear is linked to the next in the chain. When the gears shift, they engage different forks and collars. The reverse gear, which is always turned the opposite direction to the others, would never engage while the car was moving forward. As a result, the gears would make a noise and the car would not move forward.

When a vehicle shifts gears, the gear selector fork slides the blue gear to a new position. It makes contact with the collar, which has a corresponding hollow. The collar and blue gear then spin together and lock together. A small motion of the stick shift engages a different gear. However, this doesn’t work in all cars. Unlike the stick shift in a manual transmission, dual-clutch automatic transmissions have many advantages over manual transmissions.
Small gears

The car transmission uses a combination of large and small gears. The large gear is connected to the transmission shaft by a belt, and both rotate at the same speed and deliver power. The ratio between the two gears is called gear ratio, and is measured by the number of teeth on each gear. A gear with 60 teeth would be connected to a gear with 20 teeth, and vice versa. The ratio between the two gears is 3:1.

A small gear selector can be located on the instrument panel, allowing you to shift gears manually. To select a gear, you push it forward. For a large gear selector, you push it left and move it forward. When the selector reaches the position “P”, the transmission is mechanically locked. You can start the vehicle in this gear, but you must stop stationary in order to engage it. In some cases, you can manually shift gears by pressing the small gear selector on the car dashboard.
Torque converter

A torque converter for car transmission works by multiplying engine torque. It has several components, including a turbine with specially curved vanes and an impeller. The turbine is connected to the input shaft of the transmission. The torque converter assembly also contains a stator, also called a reactor. Its purpose is to increase the torque of the car when it is driving. To do this, the fluid flowing through the impeller passes through a turbine and hits its blades. The turbine then spins and moves the car.

Historically, cars used manual transmissions, but now nearly all automobiles have automatic transmissions. Manual transmissions provided better fuel economy and range, but they were considered less efficient. In the early years of the automobile industry, torque converters were referred to as “slushboxes” because they didn’t work well and made the car transmission irrelevant. But with the development of hybridization, electrification, and autonomous driving systems, the demand for car transmissions will only increase.

Idler gear

In the car transmission system, the idler gear is the primary component for the smooth and efficient running of the car. The angular velocity and acceleration of the engine are perturbed when the idler gear impacts the active gear, and the idler gear experiences similar effects with respect to the first gear speed condition. The basic sound pressure level is the lbasic value of the idler gear. Its equivalent displacements gradually approach those of an active gear, with the number of impacts increasing, the lbasic value is decreased.

Idler gears are used to transmit rotation between two shafts that are far apart in the transmission. The bigger the gear, the larger the space it will occupy. The mass and rotational inertia of the gear are proportional to their radius, and the more the gears are, the more torque they will transmit. Another form of transmission is through toothed belts or chains, which are also capable of transmitting torque over great distances.

Reverse gear

In most cars, you can engage the reverse gear with a single click, while in manual transmission cars, you need to be a bit more adventurous to reverse. In fact, it can cause significant damage to the transmission if you fail to reverse the vehicle at the right time. Here’s what you should watch for:

First, make sure that your vehicle’s gearbox has a reverse gear. Reverse gears are locked to the output shaft by a lockout ring. This means that if you attempt to shift into reverse while moving forward, you will have to use the parking brake. In manual transmission cars, a lockout ring may be damaged, preventing you from shifting into reverse while the car is moving forward. When this happens, you may not be able to shift into reverse.
