5 DESCRIPTION
[0001]. The present invention relates to a caliper for a disc brake, for example for a
motor vehicle, as well as a control system and a motor vehicle comprising such a disc brake
caliper.
[0002]. In particular, in a disc brake, the brake caliper is arranged straddling the
10 peripheral outer margin of a brake disc. The brake caliper usually comprises a body having
two elongated elements, or portions, which are arranged so as to face opposite braking
surfaces of a disc. Clutch pads are provided arranged between each elongated element of the
caliper and the braking surfaces of the brake disc. At least one of the elongated elements of
the caliper body has at least one cylinder adapted to accommodate a hydraulic piston capable
15 of applying a thrust action to the pads, abutting them against the braking surfaces of the disc
to apply a braking action to the vehicle.
[0003]. The brake calipers usually are constrained to a support structure which
remains firmly connected to the vehicle, such as, for example a suspension of a vehicle, more
particularly a fork or swingarm of the suspension of a motor vehicle.
20 [0004]. In a conventional arrangement, one of the two elongated elements has two or
more attachment portions of the caliper body to the support structure, for example by
providing slots or eyelets, for example arranged axially, or through holes, for example
arranged radially, adapted to receive screws for fixing the caliper, which are accommodated
with the ends thereof in threaded holes provided on the caliper support.
25 [0005]. In a conventional caliper body construction, the elongated elements arranged
facing the braking surfaces of the disc are connected together by bridge-like elements
arranged straddling the disc.
[0006]. A caliper body of this type is described in JP2008045737A. Figure 1 of
JP2008045737A shows a caliper body of the floating caliper type, placed straddling a brake
30 disc. This caliper body comprises two elongated elements, the ends of which are mutually
connected by bridges.
[0007]. The caliper comprises various components mounted to the body, such as
pistons, seals, bleed devices and brake fluid feeding pipes.
3
5 [0008]. Conventionally, the caliper body is made of metal, such as, for example
aluminum or aluminum alloy or cast iron. The caliper body can be obtained by casting, but
also by mechanical stock removal machining, as well as forging.
[0009]. Desiring to stop or decelerate the vehicle, the driver applies a force to the
brake pedal, in the case of a motor vehicle. Such a force on the brake pedal applies, through a
10 brake pump, a brake fluid pressure which, through a pipe, is applied to the brake fluid present
in the hydraulic circuit placed inside the caliper body to reach the cylinders where the
pressure is applied to the bottom surface of the bottom of the pistons, thus forcing them to
close against the pads, which in turn abut against the braking surfaces of the disc.
[0010]. The pressure action of the brake fluid is also applied to the bottom wall of the
15 cylinder, thus causing a reaction in the caliper body which deforms it away from the disc
surfaces. This deformation of the caliper body leads to an increase in the piston stroke, and
thus to an increase in the brake pedal stroke.
[0011]. The caliper body also deforms as a function of the torque applied by the action
of the pistons which, by abutting the pads against the braking surfaces of the disc, apply a
20 deformation moment in directions which form torque arms with respect to the fixing points of
the caliper body to the support thereof. These torques also deform the caliper body in a
tangential and radial direction with respect to the disc, as well as in an axial direction.
[0012]. Therefore, the caliper body must have sufficient structural rigidity so as to
ensure that this deformation of the caliper body caused by the braking action is maintained
25 within acceptable values, which in addition to avoiding damage to the braking system, do not
create the feeling of a yielding braking system to the driver, thus resulting in an extra travel
of the lever or pedal of the braking system and creating a "spongy" system feeling. This need
urges having highly rigid structures for the bodies of the calipers, and thus increasing the
overall size and weight thereof.
30 [0013]. On the other hand, since the caliper body is constrained to the vehicle
suspension and arranged straddling the disc, it is one of the unsprung masses intended to be
reduced as much as possible in order to increase vehicle performance.
[0014]. JP2008045737A shows a caliper on which a protective shield is mounted
which carries a recessed LED or LCD monitor for showing the light warnings.
4
5 [0015]. Furthermore, JP2008045737A shows a solution in which there is provided a
light tube which is fastened to both ends of the caliper and extends around the braking surface
externally facing the vehicle.
[0016]. Further examples are given by publications US2009141514A1, US5259483,
US7144142, US2004042227. All these solutions have light sources and also diffusers which
10 are placed or recessed in covers or shields applied to the caliper bodies, or light sources
surrounding the brake disc.
[0017]. Therefore, there remains a strong need to propose the lighting of a wide area
around the brake with at least one individual light source, and in particular, above the caliper
body, away from the brake and from the disc, that is radially externally to the brake so as to
15 illuminate at least a part of the vehicle and not just the brake or wheel alone, when required.
[0018]. Simultaneously, there remains a strong need for this lighting source to be
energy efficient.
[0019]. These and further objects are achieved by a brake caliper as described in claim
1 appended hereto, as well as a motor vehicle according to claim 8 and a lighting system of a
20 disc brake as described in claim 9.
[0020]. Further objects, solutions and advantages are present in the embodiments
