The Working of the Manual Transmission system

The transmission system ensures optimal performance by using gearwheels of varying diameters. So for each amount of power produced by the engine, there is proper hardware with the right dimensions at place to ensure that it is transmitted to the axle effectively. It can be generally understood as if the torque increases, the diameter of the gear wheel also increases. A closer description of the parts of the transmission system and how they function is as follows.

Gear: As we have seen, gears determine or alter the relation between the speed of the engine and the speed of the axle. In automobiles, the common number of gears used is four or five.

Gear ratio: the ratio between the rates at which the input and output of a set of gears rotate

Clutch: This is a mechanism used to detach the engine from the rotating shaft, by which power relay is discontinued.

Transmission: Transmission is the mechanism by which power is transmitted to the axle. If the clutch is off, there is transmission.

Shift lever: The lever at the driver's disposal which is used to shift between gears according to speeds.

H pattern: A pattern in which the gears are arranged, so that shifting between them is properly channeled.

The initial position in a vehicle is 'neutral'. This is a position in which there is no connection between the engine's rotation and the rotating shaft. To make the vehicle move, the rotating shaft has to be connected to the engine. To make the shift from neutral position to the first gear, the clutch is first used to disengage the engine from the rotating shaft. When the gear is shifted, there area few internal components that come into play.

The gear selector fork: The shift lever directly leads to the gear selector fork. According to the shift, the fork moves the collar between the gear wheels.

The collar: The collar is the physical component hat moves to and fro attaching itself to gearwheels of varying sizes. A collar is used between two gearwheels and so in case of five gears, the number of collars would be three. All the collars are equal in diameter.

The lay shaft: The rotational power from the engine is not directly connected to the gearwheels that is in contact with the collar. The lay shaft is the component which first receives rotation from the engine. An the lay shaft is the component that determines the quality of power relay, by having sizes from small to large.

Gearwheels: As said earlier, the more the torque is, the longer the diameter of the gearwheel is. But technically, it's the lay shaft that fits the description. Since the gearwheels only connect to the lay shaft , their diameters decrease as the torque increases. The speed of rotation however, does not get altered by the size of the gearwheels because, all the collars are of equal size, and connects itself on a particular circumference of the gearwheel. This means that the gear wheel only relays whatever rotational force the lay shaft produces.

The idler-wheel: The reverse gear is n essential aspect in a gearbox, since moving backward is inevitable in a vehicle. But the direction has to be reversed. The rotation from the engine is the same till the lay shaft as in the case of other gears. But the reverse gear has an additional component, called the idler-wheel. It is simply an extra gearwheel introduced in between he lay shaft and the gear wheel. Since any two connected gearwheels will have an opposite spin, the idler-wheel changes the direction just by being present.

Safety Tips for Driving in Rain

Driving in the rain is a scary thing. If it is night then it is even more difficult to drive. Whether it is night or day, it is better to drive slowly when it rains. Because when the roads are wet the traction of the tires decreases. Rain affects the drivers perception that makes it difficult to see through the rain.

  • Steering and control: Keep the steering under control by keeping both the hands firm on the steering. Keep away from distractions like cellphone. They will deviate your concentration from driving. Keep a watch on the sides and back, as it helps you to know the situation around you and or any threats such as falling of trees or power lines.

  • Maintain distance between vehicles: Maintaining distance between vehicle will help prevent accidents. It is better to keep distance from other vehicles, as it will let you see clearly and will give time and space to react.
  • Do not drive through the flood roads. If the flood water enters your car engine, it may damage your engine as well as your car.
  • Check the brakes after you come out from the water. If the brakes are taking time, apply slightly for a few times to get it into normal condition.
  • Take extra care when driving in nights. If you have fog lights turn on when the rain is heavy.
  • When the tires are wet, the traction will decrease, it is better to wait till the tires dry up.
  • Defog your mirrors by cleaning it properly.
  • Stay in the middle line. Water flows and stands on the sides. This will help you avoid slippery conditions.
  • Do not follow the large vehicles like truck and buses. They will spray water on the car and the visibility will decrease.
  • If you are going for a long trip and know about the rainy weather replace your old brittle wipers.
  • Don't drive beyond the visibility especially in nights. Some black colored cars are not properly visible in nights because of rain drops.
  • Don't park your vehicle under trees or power lines.
