Definitions
- the invention relates to a valve spring plate for supporting the spring forces of closing springs acting on gas exchange valves in the valve actuation of internal combustion engines, with a reinforcing part made of a low-strength material and an annular, between the reinforcing part and the closing spring arranged supporting part made of high-strength material, according to the preamble of claim 1 ,
- valve spring plate is shown, for example, in utility model DE 93 00 820 U1, in which the reinforcing part is made of fiber-reinforced plastic and the supporting part is made of an annular steel sheet.
- the support part is positively integrated into the reinforcement part.
- valve spring plate of the generic type (DE 41 20 892 A1)
- the reinforcing part is made of aluminum and the annular support part is also made of sheet steel to reduce its weight.
- the supporting part is caulked to the reinforcing part to produce a positive connection.
- the object of the invention is to propose a valve spring plate of the generic type which, with undiminished reliable function, is simpler in terms of production technology and therefore more suitable for large-scale production.
- the support part be held on the reinforcement part only by friction.
- this frictional engagement in later engine operation does not impair the reliable functioning of the valve actuation, even in the event of high valve accelerations.
- the support disk advantageously also provides radial support and stiffening of the valve spring plate.
- radial forces - starting from the gas exchange valve - can be at least partially absorbed or compensated for by means of the support disk. Adequate frictional engagement is achieved if the support part is held on a hub section of the reinforcement part with a radially inner ring section. This results in a particularly simple pre-assembly of the valve spring plate, in that the two parts are to be pushed one above the other in the axial direction.
- the support part can be of an L-shaped cross section, the radially inner ring section of which rests with a slight press fit on the hub section of the reinforcement part.
- This concept is particularly advantageous in the production of the support part from sheet steel using the deep-drawing process, the inner ring section providing a reliable frictional connection to the reinforcing part even with only a slight press fit.
- a slightly conical design of the radially inner ring section relative to the hub section of the reinforcing part (approx. 1 to 3 degrees) can compensate for any manufacturing tolerances that may occur or ensure an adequate press fit at least at local points of the connection.
- the attached schematic drawing shows a valve spring plate for a valve train of an internal combustion engine with a reinforcement part and a support part, in a longitudinal section along the valve center axis.
- the rotationally symmetrical valve spring plate 10 shown is composed of an annular reinforcement part 12 made of an aluminum alloy and an annular support part 14 made from sheet steel by deep-drawing.
- the valve spring plate 10 serves in a valve drive (not shown) for actuating gas exchange valves of an internal combustion engine in a known manner as a connecting part between the lift valve and a closing spring, the closing spring being supported on the radially extending ring section 14a.
- the valve wedges holding the valve stem are inserted into the conical recess 12a of the reinforcing part 12 when the valve train is installed.
- the support ring 14 has an L-shaped cross section, the radially inner, axially extending ring section 14b of which is held on the outer circumference of the hub section 12b with a friction fit or with a slight press fit.
- Said ring section 14b similar to the recess 12a, can be made slightly conical relative to the hub section 12b in order to ensure a sufficient frictional fit or press fit at least locally with reduced manufacturing tolerances.
- the support ring 14 can also be designed only in the form of a disk and its inner recess, which then encompasses the hub section 12b, press-fit against the hub section 12b.
