Abstract

A brake transmission shift interlock (BTSI) assembly is provided. The BTSI assembly may include an armature assembly and a flux collector. The armature assembly may include an armature component, a shaft, and a pin. The armature component may include a central through-hole defining a central axis and include a first end defining a first angle surface. The shaft may be disposed within the central through-hole and the pin mounted to the shaft. The flux collector may be mounted to the shaft and includes a second end defining a second angle surface. The armature component and the flux collector may be arranged with one another such that a first plane defined by the first angle surface is substantially parallel to a second plane defined by the second angle surface.

First claim

What is claimed is:

1 . A brake transmission shift interlock assembly comprising:
an armature assembly including an armature component, a shaft, and a pin, the armature component including a central through-hole defining a central axis and including a first end defining a first angle surface, the shaft disposed within the central through-hole, the pin mounted to the shaft; and a flux collector mounted to the shaft, the flux collector including a second end defining a second angle surface, the armature component and the flux collector being arranged with one another such that a first plane defined by the first angle surface is substantially parallel to a second plane defined by the second angle surface.

2 . The assembly of claim 1 further comprising a damper element disposed upon the shaft, the damper element and the pin are arranged with the shaft such that the damper element contacts the flux collector and constrains shaft movement along the central axis in a direction toward the pin.

3 . The assembly of claim 1 further comprising:
a spring arranged with the armature assembly to bias movement of the armature component, the shaft, and/or the pin in a first direction along the central axis; and
a switch assembly that creates a magnetic field when power is received, the flux collector being arranged with the switch assembly such that the flux collector operates as a magnet responsive to creation of the magnetic field, and the flux collector and the spring being arranged with one another such that the flux collector pulls the pin toward the flux collector when a force resulting from the magnetic field is greater than a force of the spring.

4 . The assembly of claim 1 , wherein the flux collector further includes a base, the second angle surface being spaced from the base a length substantially equal to 4.9 mm.

5 . The assembly of claim 1 further comprising a damper element, the armature assembly and the flux collector being disposed within a housing defining an internal surface, the damper element and the flux collector being arranged with one another such that the damper element constrains movement of the shaft between a base portion of the flux collector and the internal surface of the housing.

6 . The assembly of claim 1 , wherein the first plane defined by the first angle surface and the central axis define an angle substantially equal to fifteen degrees.

7 . The assembly of claim 1 , wherein the armature component and the flux collector are each arranged with the shaft such that the first angle surface and the central axis define a first angle between one another substantially equal to between ten and twenty degrees and such that the second angle surface and the central axis define a second angle between one another substantially equal to between ten and twenty degrees.

8 . A steering assembly comprising:
an armature assembly including an armature component, a shaft, and a pin, the armature component including a central through-hole defining a central axis and including a first end defining a first angle surface, the shaft disposed within the central through-hole and the pin mounted to the shaft; a flux collector mounted to the shaft and disposed thereabout, the flux collector including a second end defining a second angle surface; a spring arranged with the armature assembly to bias movement of the armature component, the shaft, and/or the pin in a first direction along the central axis; and a switch assembly that creates a magnetic field when power is received, the flux collector being arranged with the switch assembly such that the flux collector operates as a magnet responsive to creation of the magnetic field, and the flux collector and the spring being arranged with one another such that the flux collector pulls the pin toward the flux collector when a force resulting from the magnetic field is greater than a force of the spring.

9 . The assembly of claim 8 further comprising a damper element disposed about a first end of the shaft, the damper element and the flux collector being arranged with one another such that the damper element constrains lateral movement of the shaft in a first direction along the central axis.

10 . The assembly of claim 9 further comprising a housing and a bushing, the armature assembly and the flux collector being disposed within the housing and the housing defines an internal surface, the bushing being disposed about a first end of the shaft, the bushing, the internal surface, and the flux collector being arranged with one another such that the bushing constrains movement of the shaft between a base portion of the flux collector and the internal surface of the housing. in a first direction along the central axis.

11 . The assembly of claim 8 , wherein the flux collector further includes a base, the second angle surface being spaced from the base a length substantially equal to 4.9 millimeters.

12 . The assembly of claim 8 , wherein the armature component and the flux collector are arranged with one another such that a first plane defined by the first angle surface is substantially parallel to a second plane defined by the second angle surface.

13 . The assembly of claim 8 , wherein the armature component and the flux collector are each arranged with the shaft such that the first angle surface and the central axis define a first angle between one another substantially equal to between ten and twenty degrees and such that the second angle surface and the central axis define a second angle between one another substantially equal to between ten and twenty degrees.

14 . The assembly of claim 13 , wherein the armature component and the flux collector are each further arranged with the shaft such that the first angle surface and the central axis define a first angle between one another substantially equal to fifteen degrees and such that the second angle surface and the central axis define a second angle between one another substantially equal to fifteen degrees.

15 . A steering assembly comprising:
an armature assembly including an armature component, a shaft, and a pin, the armature component including a central through-hole defining a central axis and including a first end defining a first angle surface, the shaft disposed within the central through-hole, the pin mounted to the shaft to operate as a stopper; and a flux collector disposed about the shaft, the flux collector including a second end defining a second angle surface, the armature component and the flux collector are each arranged with the shaft such that the first angle surface and the central axis define a first angle between one another substantially equal to between ten and twenty degrees and such that the second angle surface and the central axis define a second angle between one another substantially equal to between ten and twenty degrees.

16 . The assembly of claim 15 , wherein the armature assembly and the flux collector are arranged with one another such that the first angle surface defines a plane substantially parallel to another plane defined by the second angle surface.

17 . The assembly of claim 15 further comprising a damper element disposed about a first end of the shaft, the damper element and the flux collector being arranged with one another such that the damper element constrains movement of the shaft in a first direction.

18 . The assembly of claim 17 further comprising a bushing disposed about a first end of the shaft, the armature assembly and the flux collector being disposed within a housing defining an i
