Description
Technical field
The present invention relates to a kind of gearshift slide bar of vehicle transmission, it is made of flat bar at least, and has at least one and be configured in engaging member on this flat bar, and this engaging member is formed on the flat bar and by the material of making flat bar and forms.
Background technique
Such gearshift slide bar and device thereof have been described in DE 10205033A1.The gearshift slide bar is made of flat bar.Flat bar seldom has foursquare cross section, and its cross section is rectangular usually.The long limit of rectangular cross section is flash normally, and depicts the height of the side of flat bar.The length of side is decided by the flat bar longitudinal length.Minor face is described is spacing between the outer rib of the flat bar side pointed to transverse to vertical pivot, and then describes out the short distance of flat bar edge surface.Edge surface usually perpendicular to or obliquely extend in the side, it is the cutting surface between the outer rib of side, produces when for example becoming flat bar by the sheet metal stamping-out.The outer rib of side thereby be the cutting seamed edge of flat bar.
Edge surface cutting surface in other words protrudes or gos deep into the external boundary of the engaging member the flat bar with pointing to ground from flat bar usually limiting with vertical pivot.The engaging member that protrudes is limited by the planar section of side on the side, and it is configured to speed changer and dials finger-like.After stamping-out, engaging member is inconsistent with the actual extension of flat bar partially, and it branches off or bend from flat bar, therefore at least partly on the side direction away from flat bar.The engaging member that gos deep into flat bar is the recess that points to together with vertical pivot in the flat bar.The example that is used for this engaging member is also to be known as the gearshift pincers of gearshift groove in DE 10205033A1.The engaging member that protrudes is the locking profile of locking device with may the making up of engaging member that is recessed into, and also shows this locking profile in DE 10205033A1, and this locking profile is setovered by spring and stretched in the lock(ing) bolt of latch.To form and meet to stop member or top be other engaging member to the edge that the through hole that refers to is dialled in gearshift to stamping-out in flat bar.
Because aforementioned engaging member and vertical pivot protrude with pointing to ground, so by sheet metal or metal bar stamping-out flat bar the time this engaging member can be set easily.To this, the stamping-out instrument only needs to have the former of the side external frame of the former of cutting edge external frame and engaging member.The engaging member that protrudes the gearshift slide bar from side direction by crooked or as described in starting by being bent to form.But this engaging member only is the position that is placed on away from gearshift slide bar periphery, thereby is not under any circumstance all can realize for the space reason.
More commonly, the engaging member that protrudes is from the side made separately, the mode by for example welding is fixed on the side then, perhaps is installed on the flat bar in other mode.
The heat that produces when welding can make gearshift slide bar generation thermal distortion, and this thermal distortion must be corrected, and therefore, needs extra-pay and/or causes coarse result.Because expense, often adopt flat material manufacturing gearshift slide bar, thereby this flat material preferably by making without the steel that is suitable for welding that quenches.Corresponding therewith, the gearshift slide bar just carries out the part or quenches fully after the welding of being everlasting is finished.In this case, the expense of quenching required can be owing to following former thereby increase, and the slide bar of for example shifting gears becomes too fat to move because of having pre-installed engaging member, thereby needs more space.Correspondingly, gearshift the pass through time of slide bar in quenching unit can increase, and required expense can increase, because the number of packages that can hold in one batch processing is less.
Summary of the invention
Therefore, the objective of the invention is to propose a kind of speed changer that can be produced by convenient and expense cheaply the gearshift slide bar and in gear.
This above-mentioned purpose has realized since getting by the described feature of power claim 1.Being on by flat bar after the part of material of the flat bar that protrudes on standing shape ground is to form the recess that forms that makes on flat bar.This described recess is limited by the material of a following part in one direction: the part that this part has been guaranteed the protrusion on the flat bar is connected with integral type between the material of flat bar.This described recess is arranged on the side at least and opens wide to be used for around the gearshift slide bar towards the periphery of gearshift slide bar on this side.Alternatively, this described recess can be selected both to open wide towards a side and opened wide towards an edge surface simultaneously.
(sky) volume of recess is suitable with the volume of the part of the material that protrudes from flat bar.This part is the material that the mode plasticity extruding from the flat bar by punching out or switching (durchstellen) goes out.Recess is to form by the material that is used to form projection is pushed when punching out and switching.
According to the embodiment of gearshift slide bar of the present invention make functors such as dialling fingers such as stop member, gearshift pincers and gearshift can be easily and thereby expense be integrated into suitably and be used for making the stamping-out process of slide bar of shifting gears.Like this, the gearshift slide bar is made in an operation with the instrument that can carry out stamping-out and punching out or switching or light cross cutting (anstanzen) as much as possible.Under the situation of stamping-out, material is cut off on the edge.Under the situation of punching out, the material of flat bar is extruded from one or more positions of flat bar and accumulates so that form stereo profile in other positions in principle.The material of accumulation is molded into the engaging member of protrusion.Under the situation of switching, thereby the material of the raised area is stretched under the prerequisite of not cutting off its fiber and plastically is out of shape to form for example protuberance of alms bowl shape.Under the situation of light cross cutting, material is cut off (being not to separate fully) partly, and a fraction of material is removed from original position and implemented plastically deformable, and no longer keeps the bonding of projection and flat bar.In addition, it is also contemplated that the mixed form of above-mentioned technology.
The present invention especially make have perpendicular to or engaging members such as dialling such as gearshift of protruding of oblique vertical pivot in flat bar refers to, gearshift pincers or stop member, the manufacturing of the gearshift slide bar of the engaging member that perhaps having is configured to shift gears at least dials finger-like, gearshift tong-like or stop member shape becomes easy.The shape of parts and the validity of position improve.
