Definitions
- the invention relates to a light box piston according to the preamble of claim 1 and claim 5.
- Such a piston is known from JP-U 64-25446.
- This piston - which in itself can be described as a light piston - should become even lighter.
- Weight is saved due to the cavities above the pin hubs, which are produced with the aid of arc-shaped quills, without the strength of the hub support being significantly impaired.
- the heat flow for bolt support is influenced.
- the heat dissipation from the piston can be improved by designing the channel as a through-opening through which oil flows.
- the inlet opening created by the quill lies to the side of the pin hubs. Due to the narrower running surface on the counter pressure side, the curved sleeve can be arranged approximately at right angles to the axis of the hub bores (in the view from above).
- the conventional casting machines which only have linear movements of the Kokil- Allow oil parts to be retrofitted with devices for pivoting the quills.
- These are pivotable side trains arranged on a circular path, each of which has an arcuate core part that tapers in cross section.
- the taper is necessary to allow the arched core part to be shaped.
- An angle of approx. 6 can be selected as the bevel for the core part.
- the bevel can be dispensed with, since the salt core can be rinsed out and removed with water, as is also the case with cooling ducts, so it does not have to be pulled out of the cast piston like a quill.
- Fig. 1 the piston according to the invention in a front view, left section
- FIG. 2 shows the piston of FIG. 1 in the sections indicated there
- Fig. 3 shows the piston in longitudinal section at the level of the curved channel.
- a box piston 1 has a running surface 2 on the pressure side, the width of which in the circumferential direction is greater than the width of the counter-pressure side running surface 3.
- Connecting walls 4 and 4 ' run approximately in the pressure-counter-pressure direction between the pin bosses 5 and the running surfaces 2 and 3. Outside the connecting wall 4' and at an angle next to it
- the hub zenite begins on the counter-pressure side with an arc-shaped channel 6 tapering in the direction of the pressure side, which for the most part runs above the pin hub in the pressure-counter-pressure direction.
- the channel 6 can end as a blind hole or be continuous.
