Definitions
- the present invention relates to a device for connecting a first and a second part, comprising first and second housings with a common axis respectively formed in these first and second parts, and a key inserted axially in the first housing with a relatively small clearance and in the second housing with a relatively large clearance.
- the object of the present invention is precisely to avoid this phenomenon and to eliminate the effects for which it is responsible.
- the device of the invention is essentially characterized in that the second housing and the key adopt at least partially the form of cylinders with non-circular bases each of which has different minimum and maximum diameters, the diameters of the second housing being greater than the corresponding diameters of the key and the maximum diameter thereof being greater than the minimum diameter of the second housing, and in that this device also comprises a holding member, pressing on one of the two parts and exerting on the key an elastic torque of twist around said common axis, tending to align the maximum diameter of the key and the diameter minimum of the second accommodation.
- the holding member is preferably constituted by a spring wire made integral with the key and the yoke respectively at first and second fixing points spaced from each other by a length portion of this wire, and this length portion extends at least partially in a direction different from that of said common axis to be subjected to a bending during a sliding of Tétrier resulting from a braking action, and thus being able to bring the latter back to the end of this action.
- the first fixing point is obtained by the introduction of the spring wire into a transverse bore formed in the key.
- the spring wire is bent at the exit of the transverse bore at an angle such that the sliding of the caliper causes a rotation of the spring wire in the bore, then the spring wire is advantageously supported on the yoke at a point of rotation located , along the length of this wire, between the first and second attachment points, and the second attachment point is located at a distance from the plane formed by said common axis and said point of rotation.
- FIG. 1 is a top view of a sliding caliper disc brake using a device according to the invention
- FIG. 1 is a front view of the brake of Figure 1;
- FIG. 3 is a detailed sectional view taken along line III-III of Figure 1;
- Figure 4 is a view similar to that of Figure 3, made on an enlarged scale and according to a slightly different section plane, and representing a key also slightly different section.
- the disc brake shown in Figures 1 and 2 is of the type comprising a yoke 1 and a stirrup 2 slidingly mounted on this yoke by means of an axial baluster 3.
- a hydraulic brake motor 4 integral with Tétrier 2 is capable of applying to a disc (not shown), integral with a wheel of a vehicle to be braked, two friction members 5 and 6 mounted on the brake by means of respective support plates 5a and 6a.
- the yoke 1 and Tétrier 2 which are capable of rotating relative to each other around the column 3 forming a hinge, are made integral with one another in rotation by means of a key 7 engaged according to an axis 8 in at least one housing 9 of the yoke 1 and a housing 10 of Tétrier 2.
- the object of the invention is in particular to prevent the necessarily large clearance between the key 7 and the housing 10 from becoming, under extreme conditions, a source of noise and a cause of wear.
- the second housing 10 and the key 7 adopt, at least in their mutual vicinity, the form of cylinders with non-circular bases, each of which has different minimum and maximum diameters.
- minimum diameter is understood here to mean, for each element considered (namely the key 7 on the one hand and the housing 10 on the other hand), the minimum distance that these two parallel lines can present while by remaining tangent to the section of this element, associated with the direction that these two lines take when they are at this distance Tune from the other.
- maximum diameter can be extrapolated from the previous one.
- the minimum and maximum diameters of the second housing 10 are respectively greater than the minimum and maximum diameters of the key 7, but the maximum diameter of the latter is greater than the minimum diameter of the second housing 10.
- the key 7 can for example take the form of a cylinder with a circular base modified by two parallel flats 7a and 7b, and the housing 10 can be of essentially rectangular shape and possibly open.
- the device of the invention also comprises a holding member adopting for example the shape of a spring wire 11 inserted in a transverse bore 7c of the key 7, the insertion point constituting a first attachment point 11a for the wire spring 11.
- This wire 11 which rests on the yoke at a second fixing point 11b, has the function of exerting on the key 7 an elastic torque, identified by the arrow C, around Common tax 8, tending to align the maximum diameter DM of the key 7 with the minimum diameter of the second housing, which has the direction of the width of the rectangle that the latter forms.
- 11b extends at least partially in a direction different from that of Tax 8, in order to be able to be subjected to a bending during the sliding of Tétrier 2 under the effect of a braking action, and thus to be able to bring Tétrier to the vicinity at least from its starting position after the end of the braking action.
- the spring wire 11 is for example bent at the outlet of the bore 7c and is further supported ( Figures 1 and 3) on a point of rotation la which is formed by a relief of the yoke 1 and is located, along the length of the wire 11, between the first and second attachment points 11a, 11b.
- the spring wire 11 preferably attacks the second fixing point 11b by means of a loop, so that this second fixing point is located at a distance from the plane passing through Taxe 8 and the point of rotation la , which allows a slight biasing of the spring wire 11 in torsion and increases the capacity of this wire to return the caliper to its position after sliding on the baluster 3.
- the key 7 may advantageously have a more advanced section than that of a segment of a circle and in particular devoid of angular points.
