。(Prior Art) Traditionally, camshafts used in vehicles have been two-piece camshafts made of Satsuma wood called Tokoura chill cams. In addition, recently, a newly developed sintered cam has been put into practical use, in which the details and cam parts are separately manufactured and joined together.

その製造方法を提供しようとするものである。(Problems to be Solved by the Invention) However, the monolithic structure of cast iron made by the conventional method has a large amount of i, which is problematic in terms of weight reduction. Although it is possible, there is a problem in that it increases the processing cost and is disadvantageous in terms of cost. That is, in general, those with one-piece structure are disadvantageous in terms of installation because they are constructed by □□□, and those with separate structure are
There is a problem in that the high temperature at the time of bonding rises to 0 heat, resulting in large thermal distortion, which increases the finishing machining allowance, resulting in an increase in processing costs. In addition, conventionally, if the shaft part and the cam part were separated, it would be possible to make them function as an integral part.
1) It has become common knowledge that HA leaks, and this was an area that we did not dare to touch. Despite the segmented structure, 'n1
It is an object of the present invention to provide an assembled camshaft for a vehicle and a method for manufacturing the same, which has high frequency characteristics and has virtually no disadvantages in terms of cost or the like.

The shim member has a cam portion fr: an implanted key fixed to the circumferential surface through the opening of the shim member, and the front i-picture portion is divided by a plane including the shaft portion of the cam shaft portion f. One semi-cylindrical cam half body and the other cam half body having a radially bulging nose part directly perpendicular to the plane form an fX structure, and the cam half body having the nose part On the inner surface of the body and the circumferential surface for fixing the cam part, a key for the front 111 self-implantation 7- is provided, and the implant is inserted into the eye valley key monument through the opening S of the shim member. In addition to inserting the locking key, the front 6-way valley halves are fixed and integrated at their abutting parts. To form a separate cam part on the part, first, a key groove is formed on the circumferential surface for fixing the cam part of the cam shaft part VCe, and then a shim having an opening is formed on the circumferential surface. Destructuring the member so that the opening matches the keyway on the circumferential surface,
Subsequently, on the outer surface of the shim member, one semi-cylindrical cam half body constituting a cam portion, the other cam half body having a nose portion on the outer surface and a keyway on the inner surface, and the whole cam half body are attached. The implanted key is fitted between the key groove of the split body and the key groove of the circumferential surface, and after being fitted, the Φ parts of both parts are welded under full pressure to be integrated. This is a characteristic feature.

and an inner surface of the cam half body having a nose portion;
A key is provided opposite to the circumferential surface for fixing the cam part, and a padded key is fitted into each key groove. The combination of the valley key groove and the implanted key makes it possible to easily position the cam part and to ensure sufficient rotational torque at the armpit. Moreover, a shim member is interposed between the cam part fixing circumferential surface and the cam part. By using this shim member, the force connecting the cam half body having the nose portion can be alleviated, and vibration and noise can be reduced. Further, the semi-cylindrical cam half body and the cam half body having a nose portion are fixed and integrated at their abutting portions. By this integration, the position and dimensions of the cam portion can be determined, and a camshaft that is integrated with a high degree of sheathness can be obtained. Historically, since the cam portion is formed on the camshaft portion made of a hollow pipe, the cam portion has a large effect on movement, can be reproduced by cargo, can be manufactured at low cost, and is a filler in terms of cost.

。The manufacturing of such assembled camshafts for vehicles is
A key groove is formed in the circumferential surface for the cam 5I2ij provided on the camshaft made of a hollow pipe, and then a shim member having an opening is attached to the circumferential surface so that the opening is aligned with the key on the circumferential surface. A cam portion is then formed on the outer surface of the cam member. One semi-cylindrical cam half body and the other cam half body having a nose portion on its outer surface and a keyway on its inner surface are connected between the keyway of the cam half body and the keyway of the circumferential surface. This is possible by inserting the implanted key and, after being fitted, welding the abutting portions of the two under pressure to integrate them.

きる。In the invention of an assembled camshaft for a vehicle, there is provided a circumferential surface for fixing a cam part provided on a cam shaft part made of a hollow pipe, and a shim having an opening interposed between the circumferential surface and the cam part. 5 material and an implanted key that fixes the cam part to the circumferential surface through the opening of the shim member, and the cam part is divided by a plane including the axis of the cam shaft part. , one cam half body having a semi-cylindrical shape and the other cam half body having a nose portion bulging in a radial direction perpendicular to the plane, and an inner surface of the cam half body having the nose portion; and the circumferential surface for fixing the cam part, respectively, with the key direction of the implanted key facing each other, and the implanted key is inserted into the valley key groove through the opening of the shim member, Since each of the cam halves is configured to be solidified and integrated at their abutting portions, the combination of each keyway and the embedded key allows for easy positioning of the cam portion, as well as rotational torque. can be sufficiently guaranteed in part i. Furthermore, the shim member can reduce the strength of the cam half body having the nose mt and reduce the vibration and noise. Furthermore, since the shim part is extremely thin, it will not cause any actual damage to the cam part before it is lifted. Further, by fixing and integrating each cam half body at the abutting portion, the positional dimensions of the cam portion can be determined, and a camshaft that is integrated with high accuracy can be obtained.

する車輛用組立カムシャフト。(1) A circumferential surface for fixing a cam part provided on a camshaft made of a hollow pipe, a shim member having an opening interposed between the circumferential surface and the cam part, and a shim member having an opening. an implanted key for fixing the cam part to the circumferential surface through the opening, and the cam part is divided by a plane including the axis of the cam shaft part.
The cam half body is composed of one semi-cylindrical cam half body and the other cam half body having a nose portion bulging in a radial direction perpendicular to the plane, and the inner surface of the cam half body having the nose portion. and the circumferential surface for fixing the cam part, respectively, providing key grooves of the implantable key in opposition to each other, and inserting the implantable key into each key groove through the opening of the shim member, An assembled camshaft for a vehicle, characterized in that each of the cam half bodies is fixed and integrated at their abutting portions.

組立カムシャフトの製造方法。(2) When forming a separate cam part on the camshaft made of a hollow pipe, first, a keyway is formed on the circumferential surface for fixing the cam part provided on the camshaft, and then a keyway is formed on the circumferential surface for fixing the cam part. , a shim member having an opening is attached so that the opening matches the keyway of the circumferential surface, and one semi-cylindrical cam constituting the cam portion is attached to the outer surface of the shim member. The half body and the other cam half body having a nose portion on the outer surface and a keyway on the inner surface are fitted with an embedded key across the keyway of the cam half body and the keyway on the circumferential surface. A method for producing an assembled camshaft for a vehicle, which comprises: fitting the camshaft together, and then welding the abutting portions of the two together under pressure to integrate the two.
