So a two-piece propeller shaft … In present work an attempt has been to estimate deflection, stresses under subjected loads & 30. Another end of the shaft is connected to the differential gear shaft. Universal joint b. Knee joint c. Slip joint Ans: a. The drive shaft (also called propeller shaft or prop shaft) is a component of the drive train in a vehicle, with the purpose of delivering torque from the transmission to the differential, which then transmits this torque to the wheels in order to move the vehicle. d = 53.19 mm. If G = 80 GN/m 2, what is the angle of twist in a length of 20 diameters? Find the maximum shearing stress in a propeller shaft 40 cm external, and 20 cm internal diameter, when subjected to a torque of 450 kNm. A propeller shaft is used to transmit torque from a transmission to a differential gear set in a four-wheel drive (4WD) vehicle or a front-engine, rear-drive (FR) vehicle. X in. In this four wheel drive vehicle, the second drive shaft is situated between a transfer gear box and the front axle. The bending depends upon rotational speed & length of propeller shaft. • The Propeller shaft with a slip joint is called telescopic propeller shaft • A slip joint consists of external splines on the end of one shaft and matching internal splines on the matching shaft (RNC) 16.8 be the distance of B from the left-hand support." Propeller Shaft | Function , types , Components and Requirement. 1. Abstract—The propeller shaft is the very important component in a vehicle, forward and reverse motion of the vehicle can be done by the shaft. Module II Transmission System Presented By Anoop P Dept. Shaft: • Shaft transmits power from Gearbox to Differential be the eccentricity, or deflection, at any point B in the shaft." This shaft is known as a propeller shaft, the overall objective is to design and weight of optimization be the weight of the shaft per inch length." A propeller shaft is used to transmit torque from a transmission to a differential gear set in a four-wheel drive (4WD) vehicle or a front-engine, rear-drive (FR) vehicle. Design of Braking Systems: Internal expanding shoe brake, friction lining material, drum brake arrangements, disc brake arrangement. 1: Torque tube type propeller shaft. It is known that one of the principal stresses equals 41 MPa in tension.
