Types of Gearbox

Today we will speak about the types of gearboxes used in automotive transmission. While ascending hills and starting, even if they are at low velocities, a car needs to get high torque. High torque is not required due to momentum when running at high speeds on highways.  There is therefore a system requirement that can adjust the torque and the speed of the vehicle depending on the road condition or when the driver is required. The gearbox is called this device.

Types of Gearbox:

The gear box is primarily divided into two transmission groups. These are Such

1. Manual Transmission Gearbox:

Different speed ratios or gear ratios are selected manually in this method of transmission. To operate this type of gearbox, special driving skills are needed. This is divided into three types depending on their design.

(A.) Sliding mesh gear box:

It's one of the oldest kind when we think about the gearbox styles. It means that equipment on the main shaft is moved either right or right to match them with appropriate gears on the counter shaft for different speeds. This type of gearbox takes its name from the sliding mesh of the gears. One downside is the fact that this gearbox is controlled with special skill and the risks of wearing and tearing of the gearbox are high.

(B.) Constant mesh gear box:

The type used in this 20th century is one of the famous. This is the transmission, all the gears are always in continuous mesh. Without turning the main shaft, the gears on the principal shaft rotat freely. Two dog clutches consist of a permanent mesh gear box. Such clutches are mounted between the knob and the second and the first and the reverse gear on the main shaft. When the left-hand dog clutch is moved to the left using the gearshift heel, the clutch gear is mixed and the vehicle is driven at high speed. The engine works on the second gear if this clutch slips right and fastens with a second gear. So we can move the dog clutch in the constant mesh box to adjust the equipment ratio. Another type of gearbox is more common as it produces low noise and less wear. This is a sliding mesh.

(C.) Synchromesh gear box:

One big problem is that the main shaft and gear to be meshed at different speeds if the driver engages the dog clutch. When this equipment is used, the dog clutch will wear and tear. A synchromesh gearbox solves this problem. This gear box is similar to the constant mesh gear box, except for the dog's clutch. 

Synchromesh gear units work on the principle that the first two gears to be engaged are positioned in a frictional contact that suits their speed, and is quickly and smoothly mounted. The synchrome acts as the cone clutch in the frictional matrix of the exterior surface of the cones. This form of transmission box is commonly used in automobiles.

2. Automatic Transmission Gear box:

The automatic transmission is unique when we think about transmission. Automatic transmission is known as a transmission in which different speeds are reached automatically. In this type of driver, only the general state of the vehicle, such as forward or reverse, is selected. When the accelerator is pressed or depressed, the selection, time and operation of the equipment for the appropriate gear speed are automatically performed. Automatic transmission doesn't need the gear changer and buckling pedal because the buckle and gear are a single unit.

Generally, automatic transmission is divided into two types:

(A.) Epicyclic gear box:

This kind of gearbox uses no sliding dogs or gears but only a tightening of brake bands on the gear drum produces different gear speeds. It is made up of a ring gear, a ring gear and a carrier's planet gear. Each unit can be kept from rotation with the brake strap in order to obtain differing speeds. The ring gear is enclosed by a brake band and includes teeth on the inner circumference. A stem or lever is used to catch the ring gear and keep its rotation on the brake plate. The sun gear is shifting with the rotation of the engine crankshaft on the clutch shaft. Both the sun gear and the ring gear have the planetary gears in constant mesh and rotatable axles with the carrier frame connected to the driver's shaft.

The spinning sun gear allows the planet's rotary gears to turn when the ring gear is locked by the brake unit. As it can not shift the ring gear. The gears of the world must climb over them. In that position, the ring equipment is used to monitor the planet's gears. It rotates the guided shaft attached to the planet transmitter. When the ring gear is released, the rotation of planetary gears rotating around their axis is free. No planetary movements occur during this position and thus the driven shaft remains stationary. There are a number of such units in the planetary gear box to achieve different speed reductions.

(B.) Hydraulic torque converter:

The electrical transformer is the same hydraulic torque converter. The torque converter's main purpose is to include the driving partner and increase the speed of the driven component. In the converter the pulse on the driving component is bolted, a turbine on the driving component is bolted and stationary guide valves are mounted between these two components. All parts are contained in a single hydraulic liquid housing.

With the driven portion, the impeller rotates and the liquid is centrifugal. A torque on the stationary leading valves exerts this liquid that flows from the rod to the turbine driver, thereby converting the torque and rpm. The torque difference from rotor to turbine depends on the stationary guide valve. This role is the machinery and clutch. This function.
