Definitions
- the invention relates to a piston for a hydraulic brake, which is made in forming processes of a metallic starting material, in particular of a flat sheet, and is designed as a unilaterally open pot with a longitudinal axis, a wall and a bottom, and on an open end is limited by an edge with an axial abutment surface which can be applied to a brake pad.
- Such a piston is known from WO 01/02745 Al. It is a cold-formed piston, which is preferably produced by deep-drawing process. This is designed relatively thin compared to cast piston, the starting material, the wall and the bottom have the same low wall thickness. So that the soil does not deform when subjected to a pressurized pressure medium, it is convexly curved with respect to a piston outer side, whereby the load causes compressive stresses in the soil. This stabilizing, constructive design of the floor results in a large dead space between the piston and an associated brake cylinder. Furthermore, the forces acting on the ground are transmitted into the wall of the piston, whereby in a transition region between the bottom and the wall, increased stresses arise. To compensate for the material at this point is folded several times. It turns out to be disadvantageous that the Folding of the material is particularly complex with respect to the design and costly, especially in relation to the production tool, is.
- a method for producing a piston for a hydraulic brake comprising the following steps: punching a disc-shaped, round blank from a starting material of a certain thickness, in particular from a piece of sheet metal, forming the blank in a pot-like hollow cylinder by means of a die and a punch and molding of the cup-shaped hollow cylinder for forming the bottom with a certain wall thickness and a cylindrical wall with a certain wall thickness.
- the wall thickness of the piston relative to the starting material is greatly reduced by the performed forming process, especially in the transition from the bottom and wall.
- a relatively thick starting material must be selected, resulting in increased manufacturing costs.
- the bottom has a substantially planar outer surface, a wall thickness of the bottom is greater than a minimum wall thickness the wall is, and at a transition area between the floor and wall, a wall thickness of the wall to the ground continuously increases and so the wall merges with a slope in the ground.
- the flat outer surface does not create any dead space in the brake cylinder, which reduces the amount of fluid in the hydraulic actuation circuit, which substantially improves the rigidity and dynamics of the actuation circuit.
- the advantageous design features protect the soil under pressure from deformation and cause a favorable transfer of the tensile and bending stress of the soil in compressive stresses in the wall of the piston.
- the slope has the effect that the mechanical stresses of the soil can be uniformly derived over a larger cross-section in the wall, whereby a concentration of the stresses is avoided.
- An advantageous further development of the invention includes that a length of the slope projected on the longitudinal axis is smaller than twice the wall thickness of the floor. This geometric restriction causes on the one hand a favorablepsbowung is achieved in the piston, so that an excessive increase in weight of the piston is avoided by an unnecessary material thickening of the wall.
- the slope is inclined relative to the longitudinal axis of the piston with an angle CC large 1 ° degree.
- a rounding is provided between the slope and the bottom.
- These Measure serves the stress-oriented design of the piston. It has a particularly advantageous effect if the rounding is at least partially formed as a recess in the material of the soil, so that at this point a wall thickness of the soil is reduced.
- the reduction of the wall thickness of the floor in the transition between slope and floor ensures that tensile forces close to the surface are distributed over the entire component cross-section of the floor, whereby the slope is relieved.
- the manufacturing costs are reduced by the wall thickness of the soil increases by the forming processes by more than 1.1 times the thickness of the starting material. As a result, a starting material with a small thickness can be used. Furthermore, the starting material may be relatively soft, since the bottom undergoes work-hardening by the forming processes, which is more than 1.3 times greater than the strength of the starting material. Both features lead to lower manufacturing costs and tooling costs.
- the contact surface of the edge is larger than a cross-sectional area at the thinnest point of the wall.
- a method of manufacturing a piston includes the following steps: Forming a disc-shaped, round blank into a cup-shaped hollow cylinder with a longitudinal axis, wherein an end face of the hollow cylinder is closed by a convexly curved bottom,
- the increase in the wall thickness of the soil is achieved by the compression of the soil in an advantageous manner, without the entire hollow cylinder is substantially involved.
- the soil and the transition region from the soil into the wall experience a work hardening by forming.
- the thickness of the starting material can be reduced, whereby the waste of raw material precipitates less, thus reducing the manufacturing cost.
- This method is particularly favorable if, by means of one or more ironing forming steps, an edge region of the compressed bottom merges into the wall, thereby producing a thickening of the wall in the transition region.
- Fig. 2 is an enlarged detail of the piston of Fig. 1 and
- an inventive piston 1 is shown in longitudinal section. This about a longitudinal axis 2 rotationally symmetrical executed piston 1 is designed as a pot open on one side with a wall 3 and a bottom 4, wherein it is bounded on an open end by an edge 5 with an axial bearing surface A, which can be applied to a brake pad, not shown ,
- the edge 5 is integrally formed on the wall 3, wherein the contact surface A is greater than a cross-sectional area Q at the weakest point of the wall 3.
- a circumferential groove 6 is rolled, which in installed state for receiving a sealing ring, not shown, is used.
- the length L of the slope projected on the longitudinal axis 2 is less than twice the wall thickness S_b of the floor 4 and is optimally of the order of the wall thickness S_b of the floor 4.
- a rounding 13 is provided between the slope 12 and the floor 4, which is partially formed as a recess 14 in the material of the bottom 4. This impact on the piston head has the consequence that at this point of the bottom 4, in contrast to the wall thickness S_b, reduced wall thickness S_r is present.
- the rounding 13 is provided with a radius R, wherein this radius R is smaller than the wall thickness S_b of the bottom 4. But it is also conceivable to make the transition from the slope into the ground without recess and with a variable radius.
- the wall thickness of the base preferably increases by about 1.1 to 1.6 times the thickness s 0 of the Starting material to, and the soil solidifies about 1.3 times relative to the starting material.
- the soil may also have a higher strength after forming, in particular 1.3 to 2.5 times the starting material.
- Such a piston 1 is used in hydraulic brake systems, wherein it is mounted axially displaceably in a bore of a brake caliper, and the piston head in the bore with a hydraulic fluid can be acted upon.
- the piston shifts when pressurized and pushes a brake pad against a brake disc. This causes a normal force between the brake disc and brake pad, as well as a frictional force.
- FIGS. 3a-f The preparation of the present piston by means of transformations, in particular cold forming.
- a starting material which is preferably sheet metal and which is usually present in rolled strips.
- a disc-shaped blank 16 is punched.
- the thickness S 0 of the blank 16 is equal to the thickness of the starting material.
- a cup-shaped hollow cylinder 15 having an outer diameter D1 is formed from the disk-shaped blank 16, which is closed on one end side by a convexly curved, hemispherical-like bottom 4 '.
- the wall thickness S w of the hollow cylinder 15 is substantially equal to the thickness S 0 of the blank 16, and the outer diameter Dl greater than the outer diameter D2 of the finished piston 1.
- Fig. 3b In Fig. 3c, 3d and 3e is shown schematically how the deformation and thickening of the convex, hemispherical bottom 4 'takes place. This is achieved by upsetting the bottom 4 '. In this way, material accumulation occurs in the floor area.
- the piston 1 has its final, planar shape with the outside diameter D2, the wall thickness S w of the wall 3 and The wall thickness S b of the leveled ground 4. By suitable additional forming steps is also possible to reduce the wall thickness of the S w, and thus adapt the wall to the requirements of the piston.
