Arrangement for a linear magnet for electronically assisted braking systems

A magnet housing device for a linear position sensor installed on a sliding element in a longitudinal direction the magnet housing device comprising:

• a magnet housing body with a first surface extending along said longitudinal direction and a second surface extending along said longitudinal direction opposite to the first surface;
• and
• a threaded bushing projecting from said second surface in a direction perpendicular to said longitudinal direction;
• wherein
• the threaded bushing comprises an outer bushing surface with a poka-yoke element, and an inner cylindrical opening in a direction perpendicular to said longitudinal direction,
• said inner cylindrical opening having an inner thread configured to receive a fixing screw.

A foot brake, comprising a brake pedal, a piston, a reservoir configured to contain a hydraulic fluid, an absorber comprising a float and configured to apply a reaction force to the brake pedal against an actuation of the brake pedal, a magnetic position sensor installed on said absorber, wherein the magnetic position sensor comprises a magnet housing device fixed, by shape coupling, to a float configured to pressurize the hydraulic fluid,

• wherein:
• the magnet housing device is a for a linear position sensor installed on a sliding element in a longitudinal direction, the magnet housing device comprising:
• a magnet housing body with a first surface extending along said longitudinal direction and a second surface extending along said longitudinal direction opposite to the first surface;
• and
• a threaded bushing projecting from said second surface in a direction perpendicular to said longitudinal direction;
• wherein the threaded bushing comprises an outer bushing surface with a poka-yoke element, and an inner cylindrical opening in a direction perpendicular to said longitudinal direction, said inner cylindrical opening having an inner thread configured to receive a fixing screw;
• said float comprises a recess configured to receive said magnet housing device, said recess including a cavity having a shape and dimensions corresponding to said threaded bushing;
• and
• said shape coupling is configured so that said poka-yoke element does not allow a rotation of said threaded bushing with respect to the float and uniquely identifies mutual position between float and the magnet housing device.
