Embodiment Construction

[0024] exist figure 1 shows a pre-punched flat blank 9 having an outer annular first area region 10 and an inner annular second area region 11 adjoining the first area region, thus overall having a smooth outer edge ring.

[0025] In this case, the outer area region 10 is designed to form a figure 2 The outer tooth portion 3 with the roof-like slope 4 and the indicator protrusions 6, 7, 8 seen in the figure are arranged on the outer circumference of the conical ring body 2 of the outer synchronous ring 1, as can be obtained by figure 2 See in detail.

[0026] as in figure 2 It can be seen in the figure that the roof slope 4 is a radial surface which is inclined in the axial direction and points in the direction of the axial end of the ring body 2 which is not formed with the external toothing 3 (according to figure 2 The axial end on the right side of the ).

[0027] as in figure 2 As shown in , the ring body 2 can be provided with a diffusion sintered coating 5 a...

Abstract

#CMT# # / CMT# The method involves pre-stamping a flat blank (9), covering an outer annular surface area (10) of a ring body, and sintering an inner annular surface area (11) of the ring body to form a sintered coating. Another sintered inner surface area is formed into a conical shape, where an external gearing is pre-stamped and index tabs are bent. #CMT#USE : # / CMT# Method for producing an external synchronizer ring. #CMT#ADVANTAGE : # / CMT# The method involves pre-stamping a flat blank, covering an outer annular surface area of a ring body, and sintering an inner annular surface area of the ring body to form a sintered coating, and hence increases technical quality of external synchronizer ring. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a perspective view of a flat blank. 9 : Flat blank 10 : Outer annular surface area 11 : Inner annular surface area.

Description

technical field [0001] The invention relates to a method for producing an outer synchronizer ring. Background technique [0002] Outer synchronizer rings provided with friction coatings or friction surfaces are usually sintered, forged or deformed from sheet metal. In a subsequent processing step, the friction surface is processed and / or a metallic, organic or carbon-containing friction coating is introduced in a materially or form-fitting manner. The introduction of metallic friction surfaces by means of galvanic or thermal methods is likewise known. [0003] An example of a cohesive connection for a sintered friction coating and a friction surface in an outer synchronizer ring is disclosed in WO 2006 / 004343. [0004] Bonding the friction coating foil to the frustoconical base body is a complex process. In particular, the fastening and dimensionally stable pressing of the coating roll or the layered section within the conical ring can be achieved with relatively little e...
