Definitions

  • the present invention relates to an improvement over a full contact annular disk brake assembly as described in U.S. patent application No. 60/512,848 filed October 22, 2003, which is hereby incorporated by reference. More particularly, the present invention is aimed at enhancing the transfer of the force from the actuator of the disk brake assembly to the brake pads mounted on the axially-movable brake pad supporting plate.
  • One aspect of the improvements is to provide an axially-movable brake pad unit of a full contact annular disk brake assembly for a vehicle.
  • This unit comprises a brake pad supporting plate and a wear compensation plate located at a back side of the support plate and coaxial therewith.
  • the unit comprises an intermediary plate located between the supporting plate and wear compensation plate, the intermediary plate being coaxial with the supporting plate and the wear compensation plate.
  • Another aspect of the improvements is to provide a method of applying a braking force on an axially-movable brake pad supporting plate of a full contact annular disk brake assembly for a vehicle, the brake assembly having a wear compensation plate located at a back side of the support plate.
  • the method comprises applying the braking force on the wear compensation plate; and transmitting the braking force to an intermediary plate located between the supporting plate and wear compensation plate.
  • FIG. 1 is a perspective view of an example of a partial full contact annular disk brake assembly, as improved herein.
  • FIG. 2 is a view similar to FIG. 1 , showing an opposite side thereof.
  • FIG. 3 is a view similar to FIG. 2, showing the brake support plate and the intermediary plate without the wear compensation plate.
  • FIG. 4 is a perspective and partially exploded view of what is shown in FIG. 2.
  • FIG. 5 is a perspective view of the intermediary plate of the brake assembly of FIG. 1 , shown from the side facing the brake support plate.
  • FIG. 6 is an enlarged side view of the intermediary plate shown in FIG. 5.
  • FIG. 7 is an enlarged perspective view of what is shown in FIG. 3.
  • FIG. 1 is a perspective view showing an example of an axially-movable brake pad unit (10) for use in a full contact annular disk brake assembly.
  • This unit (10) is designed to be operatively connected to the housing of the disk brake assembly and does not rotate around the axle of the vehicle.
  • the unit (10) essentially comprises an axially-movable brake pad supporting plate (12) on which are symmetrically mounted a plurality of brake pads (14) at a front side thereof.
  • the supporting plate (12) is preferably provided with a plurality of radiators (16) designed to promote a transfer of heat between the corresponding brake pad (14) and the atmosphere.
  • These brake pads (14) are also designed to be removably connected to the brake pad supporting plate (12).
  • the unit (10) further comprises a wear compensation plate (20) located on the back side of the supporting plate (12).
  • the wear compensation plate (20) is axially- movable with the supporting plate (12) and is mounted adjacent to an actuator (not shown) of the disk brake assembly.
  • This actuator is preferably in the form of an annular actuator using pneumatic air pressure to create the braking force. It is also possible to use a hydraulic actuator, especially if the vehicle is relatively small. The use of another kind of actuator, such as an electric actuator, is possible.
  • the wear compensation plate (20) comprises a plurality of inclined ramps (20a).
  • the relative rotation of the ramps (20a) with reference to corresponding sliding buttons (22) engaged thereon allows increasing the spacing between the brake pad supporting plate (12) and the actuator over time.
  • the rotation is effected by an actuating mechanism engaged to the toothed rack (20b). This compensates for the wear of the brake pads (14).
  • the sliding buttons (22) of the illustrated unit (10) are provided on a separate plate which is set between the wear compensation plate (20) and the brake pad supporting plate (12).
  • This intermediary plate (24) preferably includes two concentric narrow rings (24a, 24b). Using these spaced-apart rings (24a, 24b) is advantageous since it reduces the weight of the intermediary plate (24) and promotes heat dissipation.
  • the rings (24a, 24b) are connected together by pressing sections (24c). Each pressing section (24c) corresponds to one brake pad (14).
  • the sliding buttons (22) are provided at these locations.
  • the sliding buttons (22) have an inclined surface to match that of the corresponding ramps (20a). Yet, the sliding buttons (22) are preferably located right between the two concentric rings (24a, 24b).
  • Each pressing section (24c) is designed so that the force coming from the actuator is applied more evenly at the back side of the corresponding brake pad (14). In use, this force is transferred from the actuator of the brake assembly to the intermediary plate (24) by mean of the wear compensation plate (20). The force coming from the actuator is then transmitted to the braking pads (14) by the intermediary plate (24).
  • FIGS. 5 to 7 show the intermediary plate (24) and its pressing sections (24c) in further details.
  • each pressing section (24c) of the illustrated embodiment is in the form of a substantially H-shaped member generally disposed in a plane slightly laterally offset with reference to the plane in which the concentric rings (24a, 24b) are disposed.
  • Opposite ends of the pressing members (24c), at the back side thereof, may comprise a skid (24d), preferably with two contact points per ring (24a, 24b), designed to equally apply a force at a location in registry with the brake pad (14).
  • the design may otherwise take into account the fact that in use, the tangential speed on the rotor disk is not equal across the surface thereof since the tangential speed varies with the radius.
  • the pressing sections (24c) can be designed to compensate for this physical constraint.
  • pressing sections (24c) are exact shape may vary the natural frequency of the brake assembly.
  • the various physical parameters, such as the width, the thickness or the resiliency of the material, can be chosen to fit the requirements.
  • each flexible pad (30) is mounted between a pressing section (24c) and a location at the back of the supporting plate (12) in registry with a brake pad (14).
  • the flexible pads (30) act like a spring and are designed to be effective when a small braking force is applied by the actuator.
  • the flexible pads (30) will initially absorb some of the force applied by the actuator, resulting in a much better modulation of the braking force under light braking conditions.
  • FIG. 7 is an enlarged view showing how the contact between the pressing sections (24c) and the flexible pad (30) is made in the illustrated embodiment.
  • the design of the brake assembly can be different from what is shown in the drawings. For instance, it is possible to design the brake assembly with a different number of brake pads (14) than what is shown in the illustrated embodiment.
  • the number of ramps (20a) of the wear compensation plate (20) can also be different, including being different from the number of brake pads (14).
  • the intermediary plate (24) can be made of more than two concentric rings (24a, 24b), but it can also be made of a single member.
  • the pressing sections (24c) can have another shape or configuration than what is shown.
  • the sliding buttons (22) can be substituted for equivalent structures, such as rollers or the like.

Abstract

L'invention porte sur un ensemble de freinage à disque annulaire et à contact intégral comprenant une unité de patin de frein pouvant bouger dans le sens axial (10). Cette unité (10) comprend une plaque de support de patin de frein pouvant bouger dans le sens axial (12) et une plaque de compensation d'usure (20) située à l'arrière de la plaque de support (12). Elle comprend aussi une plaque intermédiaire (24) située entre la plaque de support (12) et la plaque de compensation d'usure (20). D'une manière générale, les améliorations apportées à l'ensemble de freinage permettent d'améliorer la répartition de la force sur les patins de frein (14) exercée par l'actionneur de l'ensemble de freinage et traversant la plaque de compensation d'usure (20). Ces améliorations offrent aussi des avantages significatifs aux ingénieurs concernant la modification éventuelle de la fréquence naturelle de l'ensemble de freinage.
