Description

TECHNICAL AREA

The present teachings generally relate to a caliper that includes a plurality of pistons, and preferably a fixed caliper with opposing pistons that includes a plurality of pistons on each side of a rotor, and more particularly, the plurality of pistons are configured to have a plurality of orbits and both relative to one another radially offset as well as circumferentially offset.

BACKGROUND OF THE INVENTION

Braking systems are used to slow or stop a moving device. Typically, most brake systems are used to slow or stop a vehicle. Some brake systems include a floating caliper that includes pistons on one side that move a brake pad in contact with a rotor, and then slides an opposite side of the caliper to move an opposing brake pad into contact with an opposite side of the rotor. Other brake systems are a stall brake system (opposed brake system) with opposing pistons that simultaneously move brake pads into contact with opposite sides of a rotor without the caliper moving. These stall brakes provide good stopping power and performance, but attempts are made to reduce the weight of these systems while maintaining braking power and performance. Brake systems typically have two or more pistons on each side of a rotor, and the pistons are in line following the curve curvature of the rotor. Attempts have recently been made to stagger the pistons within the respective sides of the caliper.

WO2011 / 121553 which are incorporated herein by reference for all purposes. It would be attractive to have an inboard and outboard side braking system in which each side has bores and pistons that are radially staggered and one or more of the inboard, outboard or both bores are partially radial through one or more cavities covered, completely covered radially or both. What is needed is a brake having an inboard side and an outboard side, each side having holes that are radially staggered and asymmetrically placed on a rear and front of a halving plane (or line). What is needed is a brake having an inboard side and an outboard side, each side having bores surrounded by a collar groove, the collar slots being partially radially covered by one or more cavities, completely radially covered, or both. It would be attractive to have a brake with an inboard side and an outboard side, with each side having bores that are staggered radially so that a center of each bore forms a circumferential path on a rotor to form three or more lanes, each representing a non-overlapping peripheral ring. What is needed is a brake having an inboard side and an outboard side, each side having two or more bores that are radially staggered and partially or completely stacked with one hole partially or completely placed radially above another hole and placed above Bore has a larger diameter than the hole placed below. It would be attractive to have a clip receptacle located within an opening of the caliper that assists in mounting one or more clamps on a bridge of the caliper.

DETAILED DESCRIPTION

The explanations and illustrations provided herein are intended to familiarize other professionals with the teachings, principles, and practical application thereof. Those skilled in the art can adapt and apply the teachings in accordance with the requirements of a particular use in its numerous forms. Accordingly, the specific embodiments of the present teachings set forth are not to be considered as exhaustive or restrictive in the teachings. The scope of the teachings should therefore be determined not with reference to the description above, but should instead be determined with reference to the appended claims, along with the full scope of the equivalents to which such claims are entitled. The disclosure of all articles and references, including patent applications and publications, is incorporated herein by reference. Other combinations are also possible, as will become apparent from the following claims, which are also incorporated herein by reference in this written description.

The present teachings provide a brake assembly. The brake assembly operates by generating a braking force to stop an object, such as a vehicle. However, the brake assembly may be used with a passenger car, a truck, a bus, a train, an airplane, a motorcycle, a lathe, a paper product or fabric spool, amusement rides, turbines, wind turbines, or a combination thereof. Preferably, the brake assembly is used with a vehicle, and more preferably with a passenger car. The brake assembly may include a rotor, a caliper, two or more brake pads, support bracket, no support bracket, or a combination thereof.

The caliper acts to generate a braking force that slows down and / or stops an object, such as a vehicle. The caliper includes a top and a bottom, and the top is placed radially above the bottom. The caliper may be mounted on a fixed object, and the caliper may move relative to the stationary object. For example, during a braking operation, the caliper may slide relative to a joint of a vehicle to generate the braking force so that both sides of a rotor are contacted by opposing brake pads. Preferably, the caliper may be mounted on a stationary object, and the caliper may remain static with respect to the stationary object. For example, opposing pistons may move within the caliper during a braking operation, but the caliper remains static relative to the stationary object or joint. More preferably, the caliper is a fixed caliper with opposing pistons (e.g., OPZ) having bores and pistons on both an inboard and outboard sides that move toward each other to generate a braking force during a braking operation.

The outboard side may be a side of the caliper that is outwardly oriented under a vehicle (e.g., facing a rim of a tire). The inboard side may face the lower of the vehicle. The inboard and outboard sides are opposite sides of the caliper. The inboard and outboard sides may each have a front (or end) and a rear (or end). The front side may be the side of the caliper that the rotor passes first, and the rear side may be the side where the rotor exits (or passes second). The rotor can run between the inboard and outboard sides. The front, rear or both sides may connect the caliper to a vehicle and preferably to a joint. Preferably, the inboard side connects the caliper to the joint by means of one or more mounting holes.

The one or more mounting holes act to firmly connect the caliper within a system. Preferably, the one or more mounting holes connect the caliper to a hinge. The one or more mounting holes may be a through hole that receives a fastener to form a fixed connection with a hinge. The one or more mounting holes may extend parallel to a rotor, perpendicular to a rotor, or at an angle therebetween. The caliper may include two or more mounting holes, and at least one mounting hole is placed near the front, and at least one mounting hole is placed near the back side. The one or more mounting holes may extend through a land, near a land, through an outer land, near an outer land, or a combination thereof.

The caliper may include one or more webs. The webs can act to connect an inboard side with an outboard side. The one or more webs may be placed in a central portion of the caliper. The one or more webs can in the rear area, the front area or be placed both (eg an end bar). The caliper may include one or more webs. Preferably, the caliper includes a plurality of webs (eg, 2, 3, 4, 5, or even 6 webs). The webs extend between the front and the rear over the rotor. The lands extend between the front and the rear such that during braking application, a plane extending through the front and a plane extending through the back remain substantially parallel. The webs may extend directly between the back and the front (eg at an angle of 90 degrees). The webs may extend at an angle from one side to the other. The ridges may extend at an angle of about 25 degrees or more, about 45 degrees or more, or even about 60 degrees or more, relative to the front, back, or both. The lands may extend at an angle of about 90 degrees or less, or about 75 degrees or less. If more than one web is present, the webs can have at least one section which faces away from another web. The webs can be parallel. The webs may have a portion that converges. The webs may extend from an inboard side or an outboard side to a front or a rear side. A bridge may extend from an inboard or outboard side to another bridge. For example, when a first land extends from an inboard side to a front side, a second land may extend from the outboard side into contact with the first land to connect the inboard side to the outboard side. Each of the bars can be discreet along its length. The webs may include a curved section. The ridges may have connection points that lie on a straight line, but the ridges may be curved between the connection points. As they extend between the inboard and outboard sides, the width, thickness or both of the webs can vary. The lands may be widened and widened at a location near the front, the back or both. The webs may be widest, thickest or both at the connection points. The webs may be separated by one or more openings. The webs may be interconnected along their length. The webs may be connected by a connecting web.

The tie bar may act to interconnect the lands at a location between the front and the rear. The tie bar can prevent the bars from moving forwards, backwards or in both directions. The tie bar may create stiffness in the caliper near the plurality of piston bores. The tie bar may be placed on the front, back or both sides. The caliper can be without a tie bar. The tie bar and lands may create a "U" shape, an "X" shape, an "H" shape, or a combination thereof. The connecting web may be a part of a material that extends between two webs and closes an opening between the webs. The tie bar may be placed near the inboard side. Preferably, the connecting bridge is placed near the outboard side. The tie bar may create, extend around, partially extend around, or form a combination of one or more cavities.

The one or more cavities act to dissipate heat, facilitate air movement, remove mass, allow redistribution of mass, or a combination of these. The one or more cavities may be placed near the bores, pistons, or both. The one or more cavities may be an absence of material, a reduction of material, or both. The one or more cavities may promote air movement in predetermined areas. For example, the cavities may promote the movement of air between the bores, the pistons, or both. The cavities can remove material from areas of low stress. The cavities may create turbulence in areas where laminar airflow is typically present. If there are two or more pistons, the cavities between one or more of the bores, partially radially over one or more of the bores, may extend completely radially across one or more of the bores, on a radial path of one or more bores, on a circumferential path of one of the one or multiple holes or a combination of these. If there are a plurality of cavities, at least one cavity (ie, central cavity) is centrally located. The center cavity may be placed between one or more other cavities, may be placed at or near the bisecting line, or may be both. The center cavity may be the cavity that is placed closest to the bisection plane, between the majority of the holes, or both. The one or more cavities may be placed along a rotor effective radius. The one or more cavities may be placed in a same plane (eg, a vertical plane within a front side or a rear side) as one or more of the holes. For example, if the caliper has an upper side and a lower side, then one of the holes is approximately halfway placed between the top and the bottom, the cavity may be placed about halfway between the top and bottom so that a portion of the cavity and the bore are placed within the same plane. The one or more cavities may be placed in a circumferential direction on a line with one or more holes. For example, as the rotor rotates, a point on the rotor passes through a hole and then passes through a cavity. The one or more cavities may be symmetrically placed between the holes. The one or more cavities may be placed asymmetrically between the holes. For example, the cavity may be offset to the front or the rear. The one or more cavities may be placed in a center region of the caliper. The one or more cavities may include a portion that is within the center region and a portion that is offset toward the front side or the rear side. The one or more cavities discussed herein are preferably placed in a central area. The one or more cavities may be placed at the bisection plane or bisecting line. The one or more cavities need not necessarily be placed radially above any holes.

The one or more cavities may be partially placed radially above one or more holes, two or more holes, three or more holes, four or more holes, five or more holes, or even six or more holes. The one or more cavities may be located entirely radially above no bore, one or more holes, two or more holes, three or more holes, four or more holes, five or more holes, or even six or more holes. The one or more cavities may be partially radially placed over one or more holes and placed entirely radially over one or more holes. The one or more cavities may be partially radially placed over two or more holes and placed completely radially over one or more holes. The one or more cavities may be partially radially placed over one or more holes and placed completely radially over two or more holes. The one or more cavities may be partially radially placed over two or more holes and placed completely radially across two or more holes. The one or more cavities may be partially radially disposed over one or more cuff grooves, two or more cuff grooves, three or more cuff grooves, four or more cuff grooves, or even five or more cuff grooves. The one or more cavities may be placed completely radially over one or more cuff grooves, two or more cuff grooves, three or more cuff grooves, four or more cuff grooves, or even five or more cuff grooves. The one or more cavities may extend partially over one or more cuff grooves and partially or fully radially across one or more bores. The one or more cavities may be partially or completely placed over the bores on a rear side or a front side of the caliper relative to a bisector plane. The one or more cavities may extend partially or completely radially through holes in the back and front. The cavity may extend across the front or back over a different number or amount of cavities. For example, the cavity can completely cover a hole on the front side and partially cover two holes on the rear side radially. A bisector (or -line) may extend through the cavity.

A halving line may extend through one or more of the holes, two or more of the holes, or three or more holes. The halving line can not extend through any of the holes. The halving plane, as discussed herein, can separate the caliper into two equal parts. The halving plane may separate the front from a back side or a front section from a rear section. Viewed in a cross-section, the bisection plane may be a bisector line. Thus, as discussed herein, the halving line and the halving plane refer to the same separation, where the halving line refers to a two-dimensional segment and the halving plane refers to a three-dimensional segment. The cavity may be completely placed on a back or a front of the halving plane. The cavities may be asymmetrically placed relative to the bisecting line. The cavities may be symmetrically placed relative to the bisecting line. The halving line may run through the cavity, but the amount of cavity placed on each side of the halving line need not be evenly distributed. For example, 40 percent of a cavity may be placed at a rear of the bisecting plane, and 60 percent may be placed at a front of the bisection plane. The cavity can have almost any shape.

The cavity may be round, square, oval, rhombus, pentagon, octagonal, heptagonal, hexagonal, rhomboid, plusiform, trapezoidal, crescent-shaped, semicircular, elliptical, ovate, four-petalled, arcuate, trapezoidal, parallelogramiform, kite-shaped, heart-shaped, be halfnavettenförmig, cathedral-shaped, D-shaped or a combination of these. The Cavity may have a non-geometric shape. The cavity may be a trough, a through hole, a widening or a combination of these.

A trough may act to represent an absence of material without complete removal of all material. A plurality of troughs may be placed inside the inboard, outboard or both sides. The plurality of troughs may include one or more troughs in the front side area, a rear side area, a center area, or a combination thereof. A well in a center region (i.e., a center well) may be placed between one or more other wells. The inboard, outboard or both may include one or more troughs or even a plurality of troughs. The one or more wells may be placed between one or more through-holes. The one or more wells may be placed on one or both sides of an expansion. A trough can be a thinning of a wall. A trough may extend into a wall without extending through the wall. The one or more wells may have any of the shapes discussed herein for a cavity. The one or more wells may gradually remove material until a vertex (i.e., a location with the least material) is formed. For example, the trough may be bowl-shaped with a decreasing wall thickness when measurements are taken towards the center or vertex of the trough. The cavity may have a recessed area surrounding a through hole. For example, a wall may have a thinning of material, and then at one or more locations within the well, there may be a through hole that extends completely through the wall.

The one or more through holes act to promote air movement, localized mass reduction, heat transfer, caliper stiffness, or a combination thereof. The one or more through holes may extend straight through a wall of the caliper. For example, the walls of the through-hole may form a right angle with one or both surfaces of the inboard or outboard side wall. The walls of the through-hole may be tapered while the through-hole extends through a wall of the caliper. For example, an outer surface of a wall of the caliper may include a through hole having a larger area than an inner surface of a wall of the caliper. The wall of the through-hole may have an angle of about 1 degree or more, about 3 degrees or more, about 5 degrees or more, about 10 degrees or more, or even 12 degrees or more with respect to an inside surface, an outside surface, or both. while the wall of the through-hole extends through a wall of the caliper (eg, an inboard or outboard side wall). The angle of the wall of the through-hole may vary around a boundary of the through-hole. The wall of the through-hole may have an angle of about 45 degrees or less, about 30 degrees or less, or about 20 degrees or less relative to an inner surface, an outer surface, or both, while the through-hole extends through a wall of the caliper. The through-hole may be placed between one or more wells, one or more through-holes, or both. The through holes may be placed on the inboard, outboard or both. The through holes may be placed in a back side area, a front side area, a center area, or a combination thereof. The through holes may be placed opposite a trough. For example, if a trough is placed in the inboard side, the through hole is placed on the outboard side. The one or more through holes may be discrete from an opening. For example, a connecting web can separate an opening and a through hole. However, there may not be a tie bar, and the opening and the through hole may be combined. The opening and the through hole may form an open space near the holes. The opening and the through hole may be connected at the inboard, outboard or both sides. The through-hole and the opening may be connected by one or more widenings.

The one or more widenings may act to expand a cavity, a through-hole, or both beyond an opening. The widenings may increase a width of a through-hole beyond a width of an opening. The flares may create a bulbous portion at one end of an opening. The expansions may be placed in an inboard, outboard, or both. The widenings may connect a through-hole with an opening. The flares may have a wall that may extend at an angle, as discussed herein for the through-hole, the teachings of which are incorporated herein by reference for flares. The expansion may be a distance in which a through hole extends beyond a width of an opening. The widening may be a through hole, an opening or both at a distance of 1 mm or more, 2 mm or more, 3 mm or more, 5 mm or more, or even 1 cm or more. The one or more widenings, through-holes, hollows, cavities or a combination of these may be placed between the outer land at the front end and the outer land at the rear end. The one or more widenings may be placed in a central area between outer bars in the front and the rear.

The one or more outer lands may act to connect ends of the inboard and outboard sides together. The one or more outer lands may be placed in the front area, the rear area or both areas. During a rotation of the rotor, the outer webs may be the first section that passes a point on the rotor in the front area and the last section that passes through the point on the rotor in the rear area. The outer webs may have a shape complementary to the rotor. The outer lands may include all or a portion of one or more mounting holes. The outer lands may include one or more wells, or one or more wells may be placed near the outer lands in a leading end region, a trailing end region, or both. The outer lands may include one or more openings, one or more cavities, or both. The outer webs may be free of openings, cavities or both.

The one or more openings may act to allow air to flow at a location near the bores brake pads, pistons, the rotor or a combination of these in the caliper. The one or more openings may be placed in a central area. The caliper may include one or more openings, two or more openings, three or more openings, or even four or more openings. The caliper may include 3, 4, 5, 6, 7, 8, 9, or even 10 openings. Preferably, the caliper has two or more openings. The one or more openings may be separated by one or more webs. The openings can be placed between a web and an end web or two webs. The openings may extend only over the rotor. The openings may extend from the front to the rear. The one or more openings may stop in front of an inboard, outboard or both wall. The one or more openings may be separated from a cavity by one or more connecting webs. The one or more openings may be widened into an inboard side wall, an outboard side wall, or both by one or more widenings. The one or more openings extend in a straight line from the front to the rear. The one or more openings can reflect the shape and angle of the webs. The angles of the webs may be such that the opening has a geometric shape. For example, if two webs are present and they diverge, the opening may have a trapezoidal shape. The openings may be formed between two substantially parallel webs. The openings may have a shape that is square, round, rectangular, elliptical, kite, parallelogram, rhombus, or a combination thereof. Preferably, the openings have a shape such that at least a portion of an opening extends above a bore.

The one or more bores may act to accommodate a piston so that the piston moves to produce a brake application. The one or more bores may act to align the piston such that the piston moves substantially axially between a brake on and a brake off position. The one or more holes can absorb fluid. For example, the pistons can be moved by means of a hydraulic force that pushes the pistons out of the holes. The one or more holes may receive a portion of a mechanical drive. For example, the pistons may be mechanically moved by a motor connected to a pan / linear drive that moves the pistons out of the bores. The bores may be placed within a wall of the inboard, outboard, or both in a pattern that produces brake application with substantially uniform wear of the brake pads and rotor.

The holes may be placed in a triangular pattern, a square pattern, a "V" pattern, a "W" pattern, an "M" pattern, a star pattern, a trapezoidal pattern, a reverse trapezoidal pattern, or a combination thereof. The pattern can be symmetrical. The pattern of the holes may be chamfered towards the front or the back. For example, the holes may have a "V" pattern, but the "V" may be angled toward the front. The pattern can be asymmetrical. For example, the pattern may be substantially trapezoidal in shape, with an inclination of the trapezoid on the front side different from an inclination of the trapezoid on the rear side. The holes may be offset relative to a bisector plane. For example, the holes may be at a different distance from the bisector so that a group of holes closer to the Halving level as a second group of holes. In another example, the group of holes at the back of the halving line may be spaced from the halving plane greater than the group of holes at the front of the halving line. The holes can be placed at an angle to the bisecting line. The bores may be placed at an angle of about 3 degrees or more, about 5 degrees or more, about 7 degrees or more, about 10 degrees or more, about 15 degrees or more, to the bisecting line, when from a radial line extending from one Center of the rotor extends through a center of the bore, is measured starting. The bores may be placed at an angle of about 45 degrees or less, about 30 degrees or less, about 25 degrees or less, or about 20 degrees or less to the bisecting line when viewed from a radial line extending from a center of the rotor through a center the bore extends, is measured starting. The bores may be placed at an angle spaced from each other. The angle separating lines extending through centers of the bores may be about 1 degree or more, about 2 degrees or more, about 3 degrees or more, about 5 degrees or more, about 10 degrees or more, or about 15 degrees or more , The angle separating lines extending through centers of the bores may be about 45 degrees or less, about 35 degrees or less, about 25 degrees or less, about 20 degrees or less, or about 17 degrees or less. The angle between the holes on the front may be greater than the angle between the holes on the back or vice versa. The one or more holes may be arranged radially one above the other. Extending from an underside of the caliper to an upper surface of the caliper or in a direction extending outwardly from a center of a rotor toward an outer edge of the rotor, a bore may be disposed above another bore. The one or more holes may partially overlap each other radially. For example, if a line is followed from a midpoint of a rotor to the outer edge of the rotor, one section of a hole may overlap another hole. One or more of the holes may be free of radial overlaps by another hole. For example, if there are five holes, two holes at a front of a bisector plane may overlap radially, and two holes at a rear of a bisector plane may overlap radially, and the fifth hole may be placed between the two groups of holes and the fifth hole must not necessarily overlapped by other holes. The two or more holes may be radially staggered. One or more holes may be radially staggered relative to one or more holes or two or more holes if one side includes a plurality of holes. All of two or more holes, three or more holes, or four or more holes can be placed completely radially below a cavity. Neither of two or more holes, three or more holes, or four or more holes must necessarily be placed partially radially or completely radially below the cavity. One or more of three or more bores may be partially placed radially below a cavity. One or more of the three or more holes may be placed completely radially below the cavity. One or more of the three or more holes are not partially or fully radially placed below the cavity. The front, rear, or both bores may be located outside the radial region below a cavity, partially radially below the cavity, entirely radially below the cavity, or a combination thereof. The holes in the front area may be placed outside (ie not below) an area below the cavities, and the holes in the back area may be partially radially or completely radially below the cavity or vice versa. The holes can be evenly distributed between the front area and the rear area. For example, two holes may be in the rear and two holes may be in the front. The holes in the front area may be closer to the cavity than the holes in the back area or vice versa. The holes in the front area and the holes in the rear area may be equidistant from the cavity. The bores may have a pattern such that the bores are partially radially or completely radially located under one or more of the cavities, a central cavity, or both. The holes may have a pattern such that the holes are not placed radially below a cavity. The holes may be placed such that a cavity may be placed between groups of holes. For example, the caliper may include four bores, and a cavity may be placed on a cube between the four bores similar to the five points. The holes can all be the same size (eg diameter). The holes can have different sizes. The holes can have two different sizes. The holes in the front area may be larger than the holes in the rear area or vice versa. The holes closer to the top of the caliper may be larger than the holes placed on the underside of the caliper or vice versa. The hole in the top of the back section may be the largest of all holes. The hole in the top of the front area may be the be the largest of all holes. The one or more holes may be placed between a liquid container and a sealing groove. The one or more bores may include one or more piston interfaces, or the one or more interfaces may be the bore.

The one or more interfaces in a bore may be in contact with the piston. The one or more interfaces may act to axially align the pistons within the bore. The one or more interfaces may act to support the pistons, assist in generating an axial force, or both. The one or more interfaces may be very close to the piston, such that the interfaces hold the pistons in alignment without preventing axial movement of the pistons. The interfaces may have a press fit to the pistons. The interfaces may have a sliding fit to the pistons. The interfaces may be located in a central region of the bore, at one end of the bore, or both. Preferably, each bore includes at least one interface. More preferably, each bore includes two or more interfaces. The interfaces may have different sizes. The interfaces may form an annular ring around a piston. The interfaces may be placed within the bore proximate a collar groove, a seal groove, a liquid container, or a combination thereof. An interface may be placed on each side of a sealing groove. An interface may be placed on one side of the seal groove toward an open side of the groove (i.e., a seal groove interface).

The sealing groove acts to receive a seal that prevents liquid from leaking out of the bore. The sealing groove can form a press fit with the piston. Preferably, the seal in the sealing groove forms a press fit with the piston. The sealing groove may have a cross-sectional distance greater than that of the bore, the interface, the liquid container, or a combination thereof. The sealing groove may include an elastomer or rubber ring (i.e., a gasket) that fits into the groove and prevents hydraulic fluid from escaping with the piston from the bore. The sealing groove can assist in retracting the piston. The seal groove may have a cross-sectional distance (i.e., diameter) equal to or smaller than that of the collar groove. The seal groove and collar groove may be separated by an interface (eg, a seal groove interface).

Each bore may include a collar groove. The sleeve grooves may act to receive a collar that moves with the piston. The sleeve can prevent contaminants from contacting the piston, contaminating the fluid, or both. The collar groove can form a concentric ring around the bore. The collar groove may have a cross-sectional length (eg, a diameter) that is greater than the cross-sectional length of the bore, the seal groove, or both. Each of the sleeve grooves may be partially radially covered, completely radially covered or both by another sleeve groove, bore, cavity or combination thereof. None of the cuff grooves must necessarily be placed radially below the cavity. All of the cuff grooves can be placed completely radially below the cavity. All of the cuff grooves may be partially placed radially below the cavity. One or more of the sleeve grooves may be partially placed radially below or completely radially below the cavity. A plurality of the sleeve grooves may be partially placed radially below or completely radially below the cavity. Each of the sleeve grooves may be partially radially or fully radially located below the cavity, and the associated bore may be located entirely radially below the cavity. Each of the patterns discussed herein for the holes applies to the sleeve grooves as the sleeve grooves extend around the holes. Thus, if the bore has a "W" pattern and a cuff groove is around the bore, then the cuff grooves will also have a "W" pattern. The collar groove has a larger cross-sectional length (eg, diameter) than the bore. The collar groove may have a cross-sectional length that is a factor of about 1.1 or more, 1.2 or more, 1.3 or more, or even about 1.5 or more greater than a cross-sectional length of a bore that accompanies the collar groove will is. The collar groove may have a cross-sectional length that has a factor of about 5 or less, about 4 or less, about 3 or less, or about 2 or less of a cross-sectional length of a bore that is accompanied by the collar groove. Each sleeve groove communicates with a piston and moves with the piston as the piston moves axially into and out of the bore.

The one or more pistons act to produce a brake application. The one or more pistons act to move one or more brake pads into contact with a rotor to produce a brake application. The one or more pistons may be metallic, phenolic or both. The one or more pistons move axially to urge one or more brake pads into a rotor. Opposite pistons may be opposing brake pads in each other move opposite sides of a rotor. The one or more pistons are housed within a bore and pass through a collar groove, a sealing groove, or both when moving between a brake on and a brake off position. The piston may be in contact with a sealing groove as the one or more pistons are moved axially by fluid filling the fluid reservoir and generating a force urging the piston through an open end.

The liquid container acts to hold liquid and then, during a braking application, assists in generating a hydraulic pressure that moves the piston axially. The liquid container may be located behind the bore, and the liquid container may hold liquid that moves the piston axially through the bore. The liquid container may be sufficiently large that when a user activates the brake system, the liquid moves the piston. The liquid container may form a termination end that is placed near the bore. The liquid container, the sealing groove, bore and piston may all be substantially concentric (i.e., all include a common center). The common center may pass a point on the rotor and form a "track" along the rotor.

The rotor acts to rotate with a component and then aids in slowing down or stopping the component. When contacted by one or more brake pads, the rotor is slowed down and / or stopped and aids in slowing down or stopping the component. The rotor has a radial length. The radial length may be measured from an inner circumference (eg, a bottom or an inner diameter) of a friction surface to an outer circumference (eg, an upper surface or an outer diameter) of a friction surface. The radial length may be a radius of the friction surface (i.e., the surface that is contacted by the brake pads that is outside the rotor hood). The rotor may have one or more pressure positions created by each of the pistons. The printing positions may have a center of pressure corresponding to the common center. Each of these centers creates an imaginary path on the rotor.

The tracks act to illustrate a pressure center created by a piston. The tracks act to illustrate the amount of radial length of the friction surface of the rotor used by the braking system. The one or more tracks may all overlap (i.e., form a single ring). The one or more webs may be non-overlapping (i.e., each bore may have its own ring on the rotor). The tracks can all be concentric. The tracks do not necessarily have to be concentric. There may be two or more webs, three or more webs, four or more webs, five or more webs, or even six or more webs. Each hole may have its own imaginary path on the rotor. For example, one lane one, lane two, lane three, lane four, lane five, and lane six may be present. The webs may extend from an inner periphery of the rotor to an outer diameter of the rotor and the space therebetween. Each of the tracks can be circumferential. The tracks can be offset relative to each other. The lanes can be located on the inboard and outboard sides. The inboard and outboard tracks may be mirror images of each other (eg, overlapping). The inboard and outboard tracks may be offset relative to each other. The inboard and outboard tracks may be offset in opposite directions. For example, inboard tracks may be offset toward the front, and the outboard tracks may be offset toward the rear. The webs can have an effective radius.

The effective radius (eg, the effective perimeter radius) may act to indicate the average or mean of all lanes on the rotor. The effective radius may illustrate the radius of each of the tracks as they are averaged together. The effective radius may be placed substantially at a center of the friction surface of the rotor. Preferably, the effective radius may be a center of an effective mass of the rotor, and the tracks may be substantially equally spaced on either side of the effective mass. More preferably, the tracks are equally spaced on opposite sides of the effective mass such that the effective radius of the holes overlaps the effective mass. The effective radius can be placed substantially in a center of mass of the friction surface.

The brake system includes one or more brake pads. Each brake pad includes friction material and a pressure plate. The brake system preferably includes a brake pad on each side of a rotor. The brake system includes two or more brake pads. The brake pads are held by a stop within the brake system. The braking system may include one or more stops or two or more stops. The stops prevent rotational movement (ie, in the direction of rotation of the rotor) of the brake pads during brake application when the brake pads contact the rotor. Preferably Each of the brake pads can be connected by means of a stop pin. A single stop pin may be connected to two or more brake pads. The stops can be an integral part of the caliper. For example, the pads may slide in the vicinity of one or more stops in the caliper, and the stops may assist in holding the pads within the caliper. Preferably, the caliper includes two stops, and each brake pad is inserted between the two stops. The stops may be any surface of the caliper that moves the pads into contact during rotation of the rotor, and the stops prevent movement of the pads in the direction of rotation, transferring a load to the caliper, or both. The stops can be a level wall in the caliper. The stops can be a profiled wall. The stops may be one or more strips from which the brake pads hang down, with which they are in contact, or both. A portion of the brake pads may fit into the stops. The stops can be one or more stop pins that contact the brake pad. The stops and / or stop pins may be placed on an upper side of the brake pad, a lower side of the brake pad, a rear side of the brake pads, a front side of the brake pads or a combination thereof. Each brake pad may be in contact with one or more stop pins or two or more stop pins. The caliper may include stop pins as well as stop surfaces. For example, during brake application, the brake pad may move into contact with the stop pin and then move about the stop pin in contact with a stop wall or surface of the caliper. The one or more stop pins may be connected to the caliper through one or more stop fasteners.

The one or more stop fasteners may receive one or more stop pins. The one or more stop fasteners act to connect a stop pin within the caliper. The stopper attachments may be a through hole in the caliper. The stopper attachments may be a threaded through-hole in the caliper. The stopper attachments may prevent movement of the stopper pins when a force is applied to the brake pads during a braking operation. The stopper pins, stopper mounts or both may carry a load during a forward braking operation, a reverse braking operation or both. The one or more stopper attachments may be a through hole. One of the stopper attachments may be a partial through-hole. The stopper attachments may be placed in the inboard, outboard or both. The stop fasteners, stop pins, stops or a combination thereof may therefore function in conjunction with one or more clip receivers, clamps (eg stop clamps or brake pad clamps) or both.

The one or more clips engage to support a clamp (eg stop clamp or brake pad clamp). The one or more clip receivers act to support a clamp that prevents one or more brake pads from rotating during forward braking, reverse braking, or both into the openings. The one or more clip receivers may be connected to one or more lands, one or more tie bars, one or more outer lands, or a combination thereof. Preferably, the one or more clip receptacles are part of the web. The one or more clip receptacles may extend cantilevered from the bridge. The clip receptacles may have a connection side and a storage side. The storage side can be mounted on the bridge. The connection side can receive the clamp and connect to it. The one or more clip receptacles may extend over an opening. The one or more clip receivers may include one or more hooks, lips, or both that form a secure connection with a clamp. The one or more clip receivers may extend from the forward direction toward the rear. The one or more clip receivers may extend over the rotor. The one or more clip receptacles may extend from one land to another land. The one or more clip receivers may have a constant width, thickness, or both along their length. The one or more clip receptacles may taper away from a bridge as the clips are extended. The thickness of the one or more clip receptacles may decrease as the clip receives extension away from the web. The one or more clip receptacles may have a shape that is square, trapezoidal, triangular, semicircular, rectangular, or a combination thereof. The one or more clip receptacles may connect one or more clips to the caliper, the bridge, or both. The one or more clamps may be out of contact with the brake pads during a forward brake operation (i.e., the rotor is rotating in the forward direction). The one or more clamps may contact the brake pads during a reverse brake operation. The one or more clamps can prevent the brake pads from contacting the lands.

The following figures are not necessarily to scale and are for illustrative purposes only and are not to be interpreted as limiting the claims. For example, in one figure, when discussing a backside bore related to a cavity, these teachings are believed to be extended to a bore on the front face that is related to the cavity. In particular, it is to be understood in the teachings that when a figure shows backside holes that are partially or completely overlapped by a cavity, the positions of the backside holes and the front side holes relative to the cavity can be exchanged so that the front side holes are partially or completely detached from the cavity Cavity are overlapped. Similarly, inferior discussions regarding the inboard side can be applied to the outboard side, and vice versa.
