Abstract

PURPOSE:To reduce the weight of a propeller shaft and heighten its strength, natural frequency and revolution speed, by combining a tube made of fiber-reinforced plastic, with a splined section provided by the plastic deformation of hollow members. CONSTITUTION:A tube 4 is made of fiber-reinforced plastic. A male and a female splines 6, 5 are manufactured by the plastic deformation of hollow members. The member having the female spline 5 is secured in the tube 4. The male spline 6 is engaged with the female spline 5. A dustproof cover 9 is mounted around the splines. Since the specific gravity of the tube 4 is low, the weight is reduced to heighten the natural frequency. The strength of the tube 4 can be made nearly equal to that of a steel-made one. Since the members having the splines 5, 6 are hollow, the weight is low and the flexural rigidity is high.

軒に適さない等の不具合がアった。Conventionally, the spline part of a propeller shaft was machined into a solid steel shaft for the female type to form the spline, and the spline was machined on the inside of a thick steel tubular member for the female type. It formed a nyoku spline. As a result, the weight of the propeller shaft has increased. For this reason, some types of propeller shafts are made of fiber-reinforced resin for the purpose of reducing their weight, but when used in combination with low-rigidity tubes such as fiber-reinforced resin tubes, the natural vibration of the entire propeller shaft is reduced. Problems arose, such as the number of cars being reduced significantly and making them unsuitable for high speeds.

The object of the present invention is to provide a propeller shaft that has high strength, a high natural frequency, and can rotate at high speed.

An end yoke 3 to which an end 2 is connected, a tube 4 fixed to the end yoke, a female spline part 5 fixed to the tube, and a female spline part 5 slidably fitted into the female spline part. The main parts include a female spline part 6, an end yoke 7 to which the female spline part is fixed, a universal hinge 8 connected to the end yoke, and a dust cover 9.

Since the specific gravity of is about 2, the rigidity is inferior to that of a steel tube, but the weight is reduced to about 1/4, and the natural frequency is very high. Moreover, its strength is at least the same as that of steel.

They are formed by plastic deformation into a spline shape, and are fitted together as shown in the drawings. Therefore, the weight is considerably reduced compared to a solid one, and the n1 bending rigidity is also sufficiently high.

を図ることができる。The present invention employs a combination of the above-mentioned FRP tube and hollow spline part, so it is lightweight and has high strength. Also, since the spline part is particularly light, the reduction in the natural frequency is small and the speed is high. It is possible to provide a rotatable propeller shaft which has a much better f' than the conventional example. This also makes it possible to reduce the weight of the vehicle, improve acceleration/deceleration performance, and reduce fuel consumption.
