Abstract
A railway vehicle controller apparatus having a housing in which a rotatable shaft having a first portion positioned within the housing and a second portion extending out of the housing is provided. A control mechanism is connected to the second portion of such rotatable shaft. Such control mechanism is operable by an operator of such railway vehicle. A detection unit is positioned within the housing to detect a rotational position of the rotatable shaft. The detection unit includes a unit to provide an electrical signal indicative of such rotational position of the rotatable shaft. Such a signal is used as an acceleration or deceleration command. A control resistance mechanism engages the rotatable shaft to provide a controlled resistance to rotation of such rotatable shaft.
Claims15
A railway vehicle controller apparatus, said controller apparatus comprising:
- (a) a housing;
- (b) a rotatable shaft having a first portion positioned within said housing and having a second portion extending out of said housing;
- (c) a control mechanism connected to said second portion of said rotatable shaft which is operated by an operator of such railway vehicle, said control mechanism includes a star wheel portion and a roller portion, said star wheel portion has a substantially uniform surface which in combination with said roller portion defines a plurality of step positions of said controller apparatus, said star wheel portion further includes at least one groove portion to clarify at least one position of said controller apparatus;
- (d) at least one detection means positioned within said housing for detecting a rotational position of said rotatable shaft, said detection means including a means for providing an electrical signal indicative of said rotation position of said rotatable shaft, said electrical signal being usable as one of an acceleration and deceleration command signal;
- and
- (e) a control resistance means engageable with said rotatable shaft for providing a controlled resistance to rotation of said rotatable shaft.
