Abstract
A motor cycle disc brake arrangement which overcomes at least some of the problems associated with the prior art comprises a disc brake (1) and a fork leg (5) of a motor cycle, which fork leg (5) rotatably carries a wheel, the disc brake (1) being located between the fork leg (5) and wheel so as to co-operate with a braking disc (9) mounted on the wheel. The brake (1) is preferably located symmetrically on the fork (5), thus reducing the moments of force resulting from brake application and keeping the brake (1) out of sight and away from the weather. The brake may be of the single piston, sliding caliper type, or of the opposed pistons, fixed caliper type. <IMAGE>
Description
SPECIFICATION
Improvements relating to disc brakes
The present invention relates to a disc brake arrangement for use on a motor cycle.
Considering the front forks of a motor cycle, which conventionally comprise two generally parallel elongate fork legs between which a wheel is rotatably supported, disc brakes are generally mounted behind or in front (leading or trailing) of the fork leg on one or both fork legs, the or each brake co-operating with a respective annular disc mounted on the wheel.
As the or each brake is offset from the central longitudinal axis of the fork leg to which it is attached, a moment of force results when the brake is applied, tending to twist the fork leg one way or the other. This may lead to premature wear and damage to the caliper, disc and friction pads. Further, as known motor cycle disc brakes are naturally exposed, unlike car brakes, they are continually both open to the detrimental effects of the weather and prone to being tampered with, it having been shown that in certain instances the friction pads on a parked motor cycle have been pushed into a retracted position, leading to a deficiency the next time the brakes were applied. To both protect the disc brake against the weather and to enhance its appearance, it has been known to coat the caliper with a plastics type material. However, this is expensive.
Such disc brake arrangements as described hereabove can appear bulky and awkward, detracting from the general appearance of the motor cycle. This is especially the case when anti-lock and/or anti-dive systems are provided, various bulky components of such systems having necessarily to be also mounted on the front forks of the motor cycle.
The aim of the present invention is to provide a disc brake arrangement which overcomes at least some of the above problems and which does not detrimentally affect the general appearance of the motor cycle on which it is mounted.
According to the present invention, there is provided a disc brake arrangement comprising a disc brake and a fork leg of a motor cycle, which fork leg rotatably carries a wheel, the disc brake being located between the fork leg and wheel so as to co-operate with a braking disc mounted on the wheel.
In one embodiment of the present invention the caliper is a pin sliding caliper comprising a torque taking member which is secured to the fork leg by a number of bolts, and a clamp member which is slidably supported on axial extensions of two of said bolts. Said bolts extend through apertures provided in lateral flanges formed on the leading and trailing sides of the fork leg with respect to the rotation of the braking disc and wheel, so that the caliper is arranged substantially symmetrically with respect to the longitudinal axis of the fork leg, between the fork leg and wheel. The braking disc extends through a slot provided in the torque taking member, friction pads carried by the torque taking member being located one on each side of the braking disc.
The torque taking member thus conveys all pad drag directly to the fork leg when the clamp member is actuated to engage the friction pads with the braking disc: suitable antisqueal shims and anti-rattle springs locating the friction pads in the torque taking member.
In another embodiment of the present invention the brake caliper is of the opposed piston type with the caliper bolted to two lateral flanges formed on the leading and trailing sides of the fork leg with respect to the rotation of the braking disc and wheel, so that the caliper is arranged substantially symmetrically with respect to the longitudinal axis of the fork leg between the fork leg and the wheel.
The caliper straddles the braking disc and carries friction pads which can be engaged with opposite sides of the braking disc by the application of hydraulic pressure within the caliper on said opposed pistons.
In a still further embodiment of the present invention, the brake caliper is of the reaction type with the caliper axially slidably mounted on the axial extensions of two bolts secured to two lateral flanges formed on the leading and trailing sides of the fork leg with respect to the rotation of the braking disc and wheel.
The caliper is thus arranged substantially symmetrically with respect to the longitudinal axis of the fork leg, between the fork leg and the wheel, so as to be slidable on said axial extensions towards and away from the wheel under the action of a hydraulic actuator located in the inboard limb of the caliper. The caliper straddles the braking disc and the outboard limb of the caliper has a recess into which part of the fork leg extends: The Out- board friction pad is keyed to said outboard limb, and the inboard friction pad is slidably carried by the portion of the caliper between said caliper limbs.Thus, when the hydraulic actuator is operated, the inboard limb is pressed against the braking disc, and reaction forces cause the caliper to slide on said axial extensions relative to the inboard friction pad and the braking disc; the outboard friction pad being thus applied to the opposite side of the braking disc by said outboard limb. All pad drag forces are thus transferred to the fork leg via said bolts in this embodiment.
In all of the above-described embodiments the caliper is located generally symmetrically of the fork leg directly between the wheel and the fork leg. Thus the moment of force evi- dent in the prior art leading and trailing caliper arrangements does not occur, or is reduced to thus reduce the likelihood of premature wear or damage. Further, the disc brake can be more securely and rigidly attached to the fork leg by virtue of the brake being located squarely behind the fork leg as opposed to one end region of the caliper being attached to- the fork leg as in the leading and trailing prior art constructions. Additionally, as the caliper is positioned out of the normal line of sight behind the fork leg, the aesthetics of the front fork construction can be enhanced.
The present invention will now be further described, by way of example, with reference to the accompanying drawings, in which: Fig 1 is a side view of one embodiment of a- caliper arrangement constructed according to the present invention;

Fig.8 is a cross-sectional view taken along line B'-B' in Fig.6;; Fig.9 is a cross-sectional view taken along line D'-D' in Fig.6; Fig.10 is a cross-sectional view taken along line C'-C' in Fig.7; Fig.1 1 is a side view of a still further embodiment of the present invention; Fig.12 is a cross-sectional view taken along line A"-A" in Fig.1 1; and Fig.13 is a cross-sectional view taken along line B"-B" in Fig.12.
The embodiment of the present invention illustrated in Figs. 1 to 5 of the accompanying drawings comprises a pin sliding caliper 1 mounted symmetrically of the longitudinal axis 3 of a fork leg 5, between the fork leg 5 and a wheel 7 carried by the fork leg 5.
As best seen in Fig.2,- a pair of pin sliding calipers 1 are mounted, one on each of the fork legs 5 forming the front forks of a motor cycle. Each caliper 1 co-operates with an annular braking disc 9, said braking discs 9 being mounted one in each axial end region of the hub 11 of the wheel 7.
The pin sliding calipers 1 of Figs. 1 to 5, each comprise a -torque taking facility 13 and a clamp member 15, the clamp member 1 5 incorporating a hydraulic actuator 17 for use in applyin-g the brake. The torque taking facility 13 comprises members (see Fig.3) bolted to leading and trailing lateral extensions 19 of the fork leg 5 respectively, by two pairs of bolts 21,23, the bolts of one pair 21 each having axial extensions 25 on which the clamp member 15 is axially slidably mounted. The clamp member 15 is located between said torque taking members 13 and straddles the braking disc 9 which projects through a slot 27 in the torque taking members 13.The clamp member 15 has an outboard limb 29 which engages an outboard friction pad 31, and an inboard limb 33 which houses the hydraulic actuator 17, the piston 35 of the actuator 17 engaging the inboard friction pad 37.
Both friction pads 31,37 are carried by the torque taking members 13 with an anti-rattle/anti-klonk spring 39 biasing the pads 31,37 towards a leading abutment face 41 in which ananti-squeal shim 43 is located. Thus, when the clamp member 15 is actuated all pad drag forces are transferred to the fork legs 5 directly by the torque taking member 13.
In a further embodiment of the present invention, illustrated in Figs. 6 to 10 of the accompanying drawings, parts equivalent to parts of the above-described embodiment will be identified by like reference numerals. In fact, the sole difference between this further embodiment of the present invention and the embodiment of Figs. 1 to 5, is that the embodiment of Figs. 6 to 10 uses an opposed piston type caliper 45 as opposed to a pin sliding caliper.The opposed piston caliper 45 is secured to a leading and trailing lateral extension 19 of the fork leg 5 by bolts 47, the caliper 45 having an inboard limb 49 and an outboard limb 51 which are secured together (see Fig.7) so as to straddle the braking disc 9. Each limb 49,51 houses a hydraulically movable piston 53, said pistons engaging friction pads 55 located one on each side of the braking disc 9. The friction pads 55 are carried by the caliper 45 so that all pad drag forces are transferred to the fork leg directly from the caliper 45. As in the previous embodiment, the prime consideration is the location of the caliper symmetrically of the longitudinal axis of the fork leg 5, between the fork leg 5 and the wheel 7.
In a still further embodiment of the present invention, illustrated in Figs. 11, 12 and 13 of the accompanying drawings, parts equivalent to parts of the above-described embodiments will be identified by like reference numerals.
Considering this still further embodiment, the sole difference from the above embodiments again lies in the use of a different type of brake caliper, though the prime consideration is still the location of the caliper symmetrically of the longitudinal axis of the fork leg 5, between the fork leg 5 and the wheel 7. The caliper 57 in Figs. 11,12 and 13, is of the reaction type, the caliper 57 having an inboard limb 59 which houses a hydraulic actuator 61 and an outboard limb 63 which has a recess 65 on its outer surface into which the fork leg 5 partially extends. The caliper 57 straddles the braking disc 9 and is axially slidably mounted on a pair of axially extended bolts 67 secured to leading and trailing lateral extensions 19 of the fork leg 5.The outboard friction pad 69 is keyed as at 71 to the out board limb 63 of the caliper 57 and the inboard friction pad 73 is slidably carried by the caliper 57-see Fig.13. When operated, the caliper 57 engages the friction pads against the braking disc 9, all pad drag forces being transferred to the fork leg 5 from the caliper 57 via the bolts 67 on which the caliper is slidably mounted.
In each of the above-described embodiments, the caliper is located symmetrically of the fork leg 5, between the fork leg 5 and the wheel 7. Thus the bulky brake caliper is out of sight behind the fork leg 5, thus enabling the aesthetics of the motor cycle front forks to be optimised especially if bulky and awkward anti-lock and/or anti-dive systems are also incorporated. Further, due to the symmetric location of the caliper about the fork leg, any twisting moment is at least reduced and the effect of any such moment is countered by the more rigid attachment of the caliper to the fork leg as compared to prior art leading or trailing cantilever caliper mountings. The possibility of premature wear or damage is therefore reduced.
