Abstract
A shifting arm for transmitting shifting movements is a formed part which is formed without cutting from a thin sheet. It includes a mouth recess in from an edge of the sheet, and stop faces are formed along the edges of the recess and out of the plane of the sheet.
Claims26
A sheet-metal shifting arm for transmitting shifting movements in a transmission, the shifting arm being formed from a thin sheet without cutting the sheet.
A sheet-metal shifting arm for transmitting shifting movements in a transmission, wherein the shifting arm is a formed part which is formed without cutting from a thin sheet, and which has a recess which is open in the shape of a mouth toward one edge of the shifting arm, adapted for engagement of a shifting finger.
A sheet-metal shifting arm for transmitting shifting movements in a transmission, wherein the shifting arm is a flat formed part which is formed from a thin sheet without cutting of the sheet, the formed part having one end in a fork-shape, the one end having two prong-shaped projections and having at least one edge which is formed by an angled section out of the plane of the sheet, each of the projections having a first stop face on the angled section and another opposed stop face on the other of the projections.
A sheet-metal shifting arm for transmitting shifting movements in a transmission, wherein the shifting arm has a bracket-shape and is formed from a thin sheet without cutting of the sheet;
- the shifting arm having a first wall section with a recess opening therein in the shape of a mouth opening toward one edge of the shifting arm, and the opening being adapted for engagement of a shifting finger;
- the recess being at least partially bounded by two opposed stop faces, which are formed without cutting of the sheet;
- the sheet having angled sections out of the plane of the sheet in which the stop faces are formed;
- the sheet including three further wall sections which are angled out of the plane of the sheet and angled out of the first wall section and which projects in the same direction out of the plane, and the first wall section merging integrally into the three further wall sections.
A process for forming a sheet-metal shifting arm for transmitting shifting movements, said process comprising the steps of:
- cold-forming only of sheet metal to obtain necessary accuracies of functional dimensions of said sheet-metal shifting arm;
- and
- hardening at least a portion of said sheet metal,
- said process not including a step of cutting said sheet metal.
