Yet when using its diameter greater than the hole of drive lug cross section diagonal, shortcoming is that drive lug supports in the wall portion of respective aperture with maximum two seamed edges simultaneously.Thus, exist linear but not the contact of face formula.If things go on like this, this can cause shift gear to wear and tear at the material at place, contact position.In addition, this also causes disabler or destruction.
Summary of the invention
The present invention is based on following task, that is, realized contacting between the receiving portion on the drive lug of synchronizing ring and the corresponding piece improved.
According to the present invention ground, this task solves by the method that is used to make with the synchronizing ring of at least one drive lug, and wherein, this drive lug upwards has two opposed surface of contact week, and wherein, construct the type exterior feature of the bending of surface of contact by the modified method of non-cutting.
At this, drive lug directly is configured on the synchronizing ring, thereby makes this drive lug show as the constituent elements of synchronizing ring.In order to improve wear-resisting property, the surface of contact of drive lug is processed into structure circularly with the method for non-cutting, thereby this surface of contact has crooked type exterior feature on cross section.Drive lug is constructed especially as follows, that is, the type exterior feature of drive lug in the vertical-that is to say perpendicular to cross sectional planes not change, but remain constant.Depend on the conglobate surface of contact of processing, drive lug can lie in the wall portion into the receiving portion of its setting with large size, and thus, the fret wear of receiving portion is reduced.Remodeling to the non-cutting of surface of contact has following advantage with respect to the cutting manufacturing of processing conglobate surface of contact, that is, the remodeling process is simplified, and manufacture cost is lower thus.
Preferably, the type exterior feature of the bending of surface of contact is constructed by the operated pressing tool with two acting surfaces that are recessed into basically.What therefore, be considered as the feasible modified method that is used to construct crooked surface of contact is the method for retrofiting by pressure loading, for example punching press.At this, the remodeling of two surface of contact especially side by side carries out, and that is to say, side by side uses two acting surfaces of operated pressing tool, thereby makes two surface of contact of drive lug only be processed to circle in a forming step.
According to preferred structural scheme, constructed the type exterior feature of projection especially continuously of working surface.For this is realized that the acting surface of operated pressing tool has recessed shape.When operated pressing tool was pressed to two surface of contact of drive lug, surface of contact clung to acting surface in shape, and formed the shape of complementary projection, and wherein, surface of contact has the fillet radius that equates with the radius of acting surface.
According to another preferred structural scheme, the type exterior feature of surface of contact is configured with the linear type section.In this case, only the fringe region of surface of contact is processed to circle, and wherein, the central region of surface of contact is on cross section, and linearly construct on formula ground.
The appropriate structures of the acting surface by operated pressing tool has been finished other shape with multiple curve of surface of contact.For example, constructed the type exterior feature of the surface of contact with section recessed and projection alternately, wherein, fringe region is in view of being processed to circle all the time with nonlinear contact of the wall portion of the receiving portion that is used for drive lug.
Preferably, in the fringe region of drive lug, constructed the thickening part.For making this realize that operated pressing tool has following acting surface, that is, this acting surface is bigger at the surface of contact of the plane of surface of contact internal ratio drive lug.In pressing process, material is forced to squeeze along acting surface at the fringe region of drive lug and opens, thereby makes form thickened section on this position.By this thickened section, surface of contact is enlarged, and thus, wearing and tearing danger is reduced further.
