US 2006/0230861 A1 · Neutral switch system for transmission

Abstract

A vehicle transmission includes a plurality of shift shafts that cooperate with a cornmon neutral switch to control when range shifts occur. In one example, the plurality of shift shafts includes a first shift shaft, a second shift shaft, and a third shift shaft that is positioned between the first and second shift shafts. A plunger actuates the neutral switch in response to movement of the third shift shaft along an axis. A first switch pin is positioned between the first shift shaft and the plunger and a second switch pin is positioned between the second shift shaft and the plunger. The first and second switch pins move the plunger to actuate the neutral switch in response to axial movement of a respective one of the first and second shift shafts. Thus, each of the first, second, and third shifts shafts can actuate a single neutral switch by cooperating with a common plunger.

Dependent claims

A vehicle transmission comprising:

a transmission housing;
a plurality of shift shafts disposed within said transmission housing with each shift shaft being movable along an axis;
a plunger adapted for independent actuation by each of said plurality of shift shafts;
and
a neutral switch cooperating with each of said plurality of shift shafts to control range shifts in response to actuation by said plunger.

2 more elements

A vehicle transmission comprising:

a neutral switch;
a plunger for selectively activating said neutral switch;
first and second switch pins cooperating with said plunger;
a first shift shaft movable along a first axis and cooperating with said first switch pin;
a second shift shaft movable along a second axis and cooperating with said second switch pin;
and
a third shift shaft movable along a third axis and cooperating with said plunger wherein movement of at least one of said first, said second, and said third shift shafts along a respective one of said first, said second, and said third axes actuates said neutral switch.
