Description

"Sensor housing device"

[0001] Field of the invention

[0002] The present invention relates to a housing device of a sensor, in particular a position sensor, for a braking feel simulator device for a braking system of the Brake-By- Wire ("BBW") type of vehicles with two or more wheels, actuatable by a driver by means of a brake pedal or lever, and to a braking feel simulator device provided with such a sensor housing device.

[0003] Background art

[0004] In braking systems of the BBW type, there is a decoupling between force and displacement applied to the brake pedal or lever by the driver and the resulting braking force which is applied by the calipers to the vehicle wheels.

[0005] In BBW braking systems, the force and displacement applied by the driver to the brake pedal or lever are transduced into an electrical signal which is processed by a control unit to control the actuation of the braking system calipers.

[0006] Accordingly, it is known to equip the BBW braking systems with a braking feel simulator device connected to the brake pedal or lever and configured to simulate the feel and stiffness of a brake pedal or lever of the conventional hydraulic braking systems, and thus emulate the "stiffness curve” thereof.

[0007] Braking feel simulator devices comprising a master cylinder connected to the brake pedal are known.

[0008] The master cylinder comprises a float, which is moved by the driver's mechanical action on the brake pedal and has the function of pressurizing the hydraulic fluid.

[0009] The hydraulic fluid is contained in a reservoir fluidly connected to the master cylinder by means of a hydraulic connection.

[0010] Moreover, the master cylinder is fluidly connected by means of a further hydraulic connection to an absorber, which is a device generally provided with a plurality of elastic elements arranged in series and in parallel, configured to apply an elastic reaction force in contrast to a brake pedal actuation.

[0011] The inventors also know to equip the braking feel simulator devices with sensors, e.g., position sensors, configured to detect an actuation of the braking feel simulator device, and in particular a movement of the float therein, to which a magnet detectable by the sensor is fixable.

[0012] Such sensors known to the inventors are generally placed inside a specifichousing externally connected to the containment and sliding wall of the float by a plurality of screws screwed between the housing and the float wall, in a direction transverse to the housing and the containment wall.

[0013] However, a connection of this type requires a certain minimum thickness of the containment wall in which to insert and screw the plurality of screws. The need to provide such a minimum thickness prevents the sensor from being placed at a shorter distance from the magnet connected to the float, and thus results in a greater distance, i.e., a larger air gap, between the sensor and the magnet. In order to compensate for this greater distance, an oversizing of the magnet fixed to the float is required to be correctly detectable by the sensor, which results in a greater axial size of the magnet as well as higher costs related to the magnet.

[0014] Moreover, such a connection of the housing to the outer wall of the float results in a larger axial size of the housing and thus of the braking feel simulator device.

[0015] Solution

[0016] It is the object of the present invention to provide a housing device of a sensor for a braking feel simulator device and a braking feel simulator device, such as to obviate at least some of the drawbacks highlighted in the prior art.

[0017] It is a particular object of the present invention to provide a housing device of a sensor for a braking feel simulator device and a braking feel simulator device, which have a small distance between the detector and the detected element.

[0018] It is a further particular object of the present invention to provide a housing device of a sensor for a braking feel simulator device and a braking feel simulator device, which have a small size and low costs with respect to the prior art.

[0019] These and other objects are achieved by a housing device of a sensor for a braking feel simulator device and a braking feel simulator device according to the independent claims.

[0020] The dependent claims relate to preferred and advantageous embodiments of the present invention.
