Definitions
- the invention relates to a roller tappet for internal combustion engines according to the preamble of claim 1.
- a Roller tappet is known from JP 7-208121 A.
- the invention deals with the problem, a weight-saving Storage of the role in the ram main body too to reach.
- This problem is in generic roller tappets solved by the characterizing features of the claim 1.
- Advantageous developments are the subject of Dependent claims.
- a roller tappet 1 has a tappet body with a Shank 5, the roller tappet 1 in a motor housing 4th leads, on.
- the ram main body consists of fiber-reinforced Plastic.
- In the plunger base is an axis. 6 stored, the one - dashed lines indicated in the drawing - role 2 carries.
- At the ram main body are total four elastically deformable or yielding webs 7 integrally formed, in which the axis 6 is clipped.
- a metallic component 9 through Injection molding with cast in, giving the power of a push rod 3 receives and on the axis 6 on the role of the second transfers.
- the axis 6 has an angle of about 130 ° Contact with the metallic component 9, which together with the ram main body and the integrally formed on this webs 7 serves as a bearing for the axle.
- the metallic component 9 has in its lower region a spherical recess for receiving the push rod. 3 and in its upper part two bearing webs for the axle storage on. In Fig. 2 below the webs 7 is the Dividing line between metallic component and plastic existing area of the plunger base recognizable.
