Front-wheel drive car. *The FWD platform is used in many reliable vehicles ,such as a Honda Accord or Toyota Camry. * FWD mean that the two forward vehicles are responsible for moving the car .
Main points. 1-Parts of FWD & how does it work. 2-Advantages . 3-Disadvantages . 4-FWD VS RWD .
*PARTS OF FWD. 1-gear box. it take the motion from the engine and we can modify the received velocity on it 2-differential. it is apart mounted by bolts downward the gear box and take the output motion from the gear box and deliver it to the drive shafts (CV joints). 3-drive shafts. it take the motion from the differential to the two vehicles.
*ADVANTAGES. 1- Front-wheel drive is more speedy than rear wheel drive car because of the mechanical losses reduces due to short distance between the engine and the differential . 2-Economic in using petrol due to the push power is nearby to the engine. 3-It is also lighter than the rear-wheel drive.
*DISADVANTAGES. 1- FWD depends on drive shafts which contain CV joints which allow the vehicles to movein all directionsthat have a lot of defects. 2-Expensive maintenance. 3-Difficulty to direct the car when we start moving with high speed. 4- Unbalanced car because the mass is concentrated at the forward part of the car only .
*FWD VS RWD 1- Load on tires *The biggest benefit to rear wheel drive is that it spreads the loads of the car across all four tires of a car , the rear wheel do the pushing while the front wheels are for the steering duties . * In front wheel drive cars the front tires must perform both functions , the engine acceleration\deceleration forces act on the front wheels that’s beside the steering duties. 2- Better weight balance *Rear wheel drive cars have the engine in the front and the drive components in the rear , but the front drive cars have every thing up front . *So by balancing the front and rear of the car you can improve the handling, acceleration, braking and thus safety of the car .
3-Torque Steer *Front wheel Drive cars have a problem known as Torque Steer. This occurs when the acceleration of the engine effects the cars steering . Since the driveline is connected to the steering wheels the torque of the engine applies force to the front wheels causing the car to pull to the right during acceleration. *Rear Drive cars do not have this problem since the engine is not connected to the steering gear.
