发明名称 Shift fork for a gearbox of a motor vehicle and method for manufacturing the shift fork
摘要 Gearshift fork (1) has gear stages, fork ridges (2) from which two sides (3a, 3b) are produced, drag bearing receivers (5a, 5b) for a bearing pin in the region of the fork ridges, and an operating lever for operating the gearshift fork extending from the region of the ridges. The fork ridges, sides, drag bearing receivers and operating lever are made from a one-piece steel sheet. An Independent claim is also included for a process for the production of the gearshift fork. Preferred Features: Both fork sides and the operating lever form parts bending from the fork ridges. Both fork sides and the operating lever run in three different planes (E1, E2, E3) extending vertically toward the pivoting axis (A) of the gearshift fork.
