Abstract
Monostable shifting mechanism, in which two shifting channels are provided for the shift lever. “Monostable” means that the shifting element or the shift lever has only one stable position. As a function of the actual “operating condition” of the shifting mechanism, certain other operating conditions can be selected by means of the deflection of the shift lever. For this purpose, the shift lever is deflected manually in either one or the other shifting channel and, after the release, automatically returns into the stable starting position from any possible deflected position.
Claims20
A shifting mechanism comprising:
- a shifting element for selecting a plurality of shifting conditions, wherein the shifting conditions include a reversing condition, a neutral condition (N), a drive condition, a step-by-step shifting condition in which manual shifting of forward gears takes place;
- a first shifting channel for the shifting element;
- and
- a second shifting channel for the shifting element, wherein the shifting element has a stable position in the first shifting channel and is deflectable to select any one of the shifting conditions and for the manual shifting of the forward gears, and wherein the stable position in the first shifting channel is the only stable position of the shifting element and, after the shifting element is deflected and released, the shifting element automatically returns to the stable position.
A method of making a shifting mechanism comprising the steps of
- providing a shifting element with a plurality of shifting conditions, wherein the shifting conditions include a reversing condition, a neutral condition, a drive condition, a step-by-step shifting condition in which manual shifting of forward gears takes place;
- providing a first shifting channel for the shifting element;
- providing the shifting element with a single stable position in the first shifting channel;
- providing a second shifting channel for the shifting element;
- making the shifting element deflectable to select any one of the shifting conditions and for the manual shifting of the forward gears;
- and
- providing that after the shifting element is deflected and released, the shifting element automatically returns to the stable position.
