Automotive Products:Propeller Shafts

Functions and Roles

Where the engine and axles are separated from each other, as on four-wheel-drive and rear-wheel-drive vehicles, it is the propeller shaft that serves to transmit the drive force generated by the engine to the axles. The longer the shaft, the more liable it is to bend, and bending is further promoted when rotation is applied causing vibrations and resulting in an increase in noise. For this reason, the propeller shaft has been designed to suppress vibrations arising from a wide range of causes.

Types of Propeller Shafts

Single-piece-type Propeller Shaft

Single-piece-type Propeller Shaft

[Vehicle models]
Used in vehicles with a short distance between the engine and axles, and MR based four-wheel-drive vehicles.

[Characteristics]
The friction welding adopted at the junction contributes to an improvement in the strength, quality, and durability of the junction. A reduction in the number of component parts and in the weight has been achieved.

   
2-piece-type / 3-piece-type Propeller Shaft

2-piece-type / 3-piece-type Propeller Shaft

[Vehicle models]
Used in vehicles with a long distance between the engine and axles, and Front engine front drive base four-wheel-drive vehicles.

[Characteristics]
The division of the propeller shaft into two- or three-parts allows the critical number of revolution to lowered preventing vibration problem from occurring, when the overall length of the shaft increased. The dynamic damper inserted into the pipe reduces the vibration and noise.
