Types of transmission

Types of transmission and it’s types ::::
Introduction ::
It’s important component of a vehicle it moves the power from the engine to the wheels there are a variety of car transmission some are automatic some are manual transmission as stick shift cars in which the driver required to complete extra steps to operate the vehicles effectively if you have wondered how does a transmission work the process varies depending on the type of transmission but what does a transmission do
What is transmission?
Transmission in a vehicle enables the gear ratio between the drive wheel and engine to adjust the car speed from slowing down and speeding up when a vehicle is stopped the transmission disconnected the engine from the drive wheels so that engine can keep idling when the wheel are not in motion transmission also enables quick acceleration from a stop and enables the engine to run slowly to cut down on wear
Types of transmission ::::
1 Manual transmission
It’s have a clutch pedal and shifter which the driver uses to change the gear manually these type of transmission consist of set of gears along a pair of shafts called the input and output shaft with a manual transmission the driver has to select the proper gear and engage or disengaged the clutch pedal the transmission uses a flywheel pressure plate the clutch to disengaged the engine from transmission the flywheel and pressure plates are connected to the engine the clutch is sandwich between them and is splined to the transmission input shaft the term push in the clutch means to release the pressure plate which disengaged the clutch push in the clutch first
Pros of manual transmission ::::
1 better for off road
2 High torque load usage
3 reliable and easier to service maintain and repair
4 not every one can drive cons of manual transmission
5 maintain and repair
6 lower resale
7 higher learning curve
2 intelligent manual transmission :::
It’s simply and quite accurately put the imt is a clutch less manual transmission it’s just a regular manual gearbox but without a clutch pedal in situation like coming down a slope this is off course without the headache of operating the clutch pedal you don’t need to lift off the accelerator when shifting gears it will help smooth in things if you do and imt cannot shift gear automatically
Advantages of imt :
1 Complete control over what gear your car is in and you don’t have to rely on the software getting it right
2 cost of an imt is also closer to that of a regular manual transmission
Drawbacks of imt :
The gear shift are not as smooth as the system relies on a single clutch that has to be modulated by an actuator
3 automated transmission amt ::
It is mechanically similar to manual transmission except that the sensor and actuators perform the clutch work and shift gear a car with amt doesn’t have a clutch pedal there is only accelerator and brake pedal. Amt uses hydraulics and computer linked with electronics control unit or ecu of the car the gear shift patterns are reprogrammed on this unit and work mainly on the present rpm range once the system guages optimum rpm the ecu engages the actuators which operates the clutch and gearbox
Benefits of amt over manual transmission ::
1 it’s convenience
2 more fuel efficient
3 rely on present rpm level
4 gear automatically change
Working of automatic transmission ::
In this engine connect to torque converter which is then connected to gear system and then to the transmission a torque converter is a vital component of an automatic transmission inside the torque converter there are parts that work in tandem with each other the outermost side has the flywheel which is connected to the engine it rotates the entire structure the rotation makes the pump push our fluid at high speed the fluid makes the turbine rotates the fluid keeps on rotating separated in two section and is kept rotating with the help of stator in the middle the turbine is connected to the shaft which connects to the rest of the system and energy transfers to the gear system

3.Planetary gear system :::::
A star is followed around by the planets and rotates it at respective speeds the gear system is called planetary gear system it consist if gear in the middle called sun – gear and 3 gear around it called planetary gears which are covered by a ring gear the planetary gears are smaller than the sun – gear the speed at which sun gear rotates will be slower than the planetary gear making the ring gear rotates faster than the sun – gear these parts in combination makes an automatic transmission the 1st automatic transmission used in production of cars was the hydromatic old mobile in the 1940s
Pros of automatic transmission :::
1 easy to use
2 comfortable driving
3 expensive to maintain and repair 

4 .CONTINOUSLY VARIABLE TRANSMISSION (CVTs) ::
They  are pulley based transmission that are primarily used in small vehicles with small engines the transmission have been used for years in snow machines and are also become more popular in hybrid vehicles recently the CVTs offers a similar driving experience to an automatic transmission but operates using a completely different mechanism in fact it does not have gears at all instead it uses a system to belts and pulley to produce an infinite range of ratios the computer fitted in these cars decides how to adjust the pulley to creat the optimal ratio for the particular driving situations. This system is consist of cones at each pulley connected by a chain belt the cones can move to increase and decrease the belt diameter to change gear ratios one pulley is connected to engine and other directs power to the wheel the width of these pulley changes based on the needed power as one gets larger as other gets smaller this allows a CVTs to deliver strong and seamless acceleration this allow a cut to deliver strong and seamless acceleration
Pros of CVTs :
1 smoothest ride
2 greatest fuel efficiency
3 faster response
Cons of CVTs ::
1 unusable in off-road conditions
2 no ability of engine breaking
Semi automatic transmission :::
It is a clutch less manual transmission that provides an alternatives to its automatic or manual counterparts this transmission is practically identical to a manual one in a typically manual vehicle the driver steps down on the clutch pedal when they want to change gears the clutch pedal is connected to the transmission through cables and pipes in a semi automatic there is no clutch pedal instead there is computer that uses processors and sensors to automatically depress the clutch when the driver signals by shifting the gear stick the vehicles computer manages engine torque, speed. accelerator pedal position and other function driving a semi automatic car would feel very similar to a manual drive except although semi automatic do have things in common with other typical transmission and they are also very different with their own sets of benefits and drawbacks
6.Pros of Semi automatic transmission ::
1 smooth shifting
2 less in efficiency in shifting
Cons of semi automatic transmission :::
1 expensive to maintain and repairs
7 .Dual clutch transmission :::
There are separate clutches for both odd and even gears which allows for incredibly fast shift these gearboxes can generally operated in a fully automatic mode with paddles on the steering wheel
Working of dual clutch transmission :::
It offer cutting edge performance with lightning fast gear change that a pure manual just cannot match these gear box are found in race car and high sports cars they are quite expensive this disadvantage is magnified by their extreme complexity which lead to more frequent and costly repairs
