Abstract
ABSTRACT OF THE DISCLOSURE
A disc brake assembly includes a torque member which carries at least one pin for slidably supporting a caliper. The one pin threadably engages the torque member and extends on both sides of the disc. A pair of friction elements are engageable with the disc to retard rotation of the latter. On one side of the disc the one pin slidably engages the caliper, while on the other side of the disc the one pin slidably engages one of the pair of friction elements. The one pin is spaced from the caliper on the other side of the disc where the one pin engages one of the pair of friction elements. The one pin cooperates with a resilient bushing on the caliper to form a sliding connection therebetween and also cooperates with a resilient bushing on the one friction element to form a sliding connection therebetween. A thermo-plastic sleeve is disposed between the resilient bushing on the caliper and the one pin, and the sleeve is disposed remote from the torque member so that when the one pin is connected to the torque member, the sleeve remains in an axial unloaded condition.

Description
This invention re].ates to a disc brake assembly.
This applica-tion is a division of copending ; Canadian Patent Applica-tion 333,993, filed ~ugust 17, 1979.
In general a pin slider disc brake, such as illustrated in U.S. Patents 3,37~,906 and 3,628,639, provides a pair of pins which extend from a torque member to sl.idably carry a caliper. Each pin forms a slidable connection on both sides of the disc with the caliper so that the caliper requires a Pair of coaxi.al openings for receiving each pin.
Consequently, the caliper of the prior art pin slider disc brake inciudes a pair of radially outwardly extending flanges so as to form -the pair of coaxial. openings. As a result the outwardly extending flanges take up space so that the construct.i.on is not compatible wi-th the small space available for many small cars, especially those cars with front wheel drive.
In addi-tion, the pin slider disc brake of the prior art utili~es a resilient ring or grommet to form a sliding connection between the pair of pins and the caliper so that the metal pins sl.idably engage the resilient rings.
The present invention resides in a brake assem~ly having a troque member which slidably supports a caliper and a pair of brake shoes which are movable .into engagement with ~he disc, the torque member releasably carrying at least one pin which slidably supports the caliper. The caliper includes an opening for receiving the one pin, and a sleeve is carried by the one win to form a slidable connection between the one pin and the caliper.
~ n a specific embodimen-t, t-he sleeve is carried by the one pin to form a slidable surface for slidably carrying the caliper relative to the one pin, the one pin cooperating with the -,leeve to dispose the sleeve remo-te -t~
i 1 63~9 rom the torque member so -tha-t when the one pin is connected to the torque member the sleeve remai.ns in an axial unloaded condition.
It is an object of the presen-t invention to provide a pin slider disc brake which is comPactly structured to fit between a small car frame and wheel assembly.
It is an additional ob~ect. oE the present invention to provide a disc brake assembly which accommodates manufacturing tolerances by providing an opening in the outer fric-tion element to receive a pin in a pin slider dis¢ brake.
BRIEF DESCRIPTION OF THE D.R~W:I:NGS
Figure 1 i.s an end view of a disc brake assembly;
Figure 2 is a top view of the disc brake assembly o~ Figure 1 with the portion along line 2-2 of Figure 1 being cu-t away; and Figure 3 is a cross-sec~ional vie~ of Figure 1 taken along line 3-3 of Figure 1.
DETAILED DESCRIPTION
A disc brake assembly 10 includes a tor~ue member 12 which is secured to a non-rotatable portion of a frame 14 via bol.ts 16. The torque member is substantially U-shaped to form a pair of radially extending arms 18 and 20. The arms form bores at 22 and 24 and the left arm 18 includes an axially extending flange 26; however, it is possible to also provide an axially extending flange for the right arm 20. The bore 22 is disposed in the flange 26 to receive a pin 28 while the bore 2~ receives a pin 30. A caliper assembly 32 is slidably carried by the pins and a hydraulic actuator 34 carried by the caliper assembly 32 cooperates with a pair of brake shoes 36 and 38 to urge the latter into fricti.onal engagement with a disc or rotor 40.
Turning to Figure 2, the caliper assembly 32 ~m/~ -2-~ 1 ~3~09 ~ cludes a pair of .radially extendiny flanges a-t 42 and 44 which form openings 46 and 48. Viewing the lef t radial - flange 42, as the right flange 4'1 is constructed similarly, the opening 46 receives a resilien-t bushing 50, such as a rubber grommet, and the pin 28 may op-tionally carry a thermo-plastic sleeve 52 to enhance sliding with the resilien-t bushing 50. The thermo-plastic sleeve 52 extends through an opening on the resilient bushing 50 and cooperates with the latter to form a sliding connection between the pin 10 28 and -the caliper 32.
The pin 28 forms a head 54 and an adjoi.ning recess 56 to receive lhe-the:rmo-plastic sleeve 52. A threaded portion of the pin 28 at 58 is engageable with a threaded portion of the bore 22 at 60. In addition, a second portion 62 of the pin 28 forms a close fit with a second por-tion 6~ of the bore 22. A small clearance between portions 62 and 64 is provided to accommodate manufacturing tolerances upon insertion of the pin 28 i nto the bore 22. A shoulder 55 on the pin 28 is engageable wi th the torque member arm 20 18 when the pin 28 is threadably engaged with the bore at 60. The shoulder 55 separates the recess 56 from -the torque member so that the thermo-plastic sleeve 52 is always spaced f rom the torque member . Therefore, the thermo-plastic sleeve is not subjected to compressive axial loading when the pin is attached to the torque member. As shown in Figure 2, the inner diameter of bushing 50 is greater than the diameter of the shoulder 55 so that the bushing 50 is free to slide on the pin 62 between the head 54 and the torque member arm 18.
The .inner brake shoe 36 includes a backing plate 66 which fits within the opening formed by the U-shaped torque member ' 2. Consequen-tly, braking -torque developed -t ~n/, (,; j ~ 3 -- ~ 1 63209 ~y the inner brake shoe 36 is -transmitted directly -to the torque member 12. Moreover, the inner brake shoe 36 releasably carries a spring 68 to retain the inner brake shoe in abutment with the underside of the caliper assembly via tabs 67 and 69 extending from the backing plate 66 so as to elminate rattle generated by the inner brake shoe. The outer brake shoe 38 also includes a backing plate 70 which is formed with projections 72. The projections extend into apertures 74 which are provided on a radially inwardly ex-tending leg 76 of the caliper assembly 32. The projections extend into apertures 74 which are provided on a radially inwardly extending ]eg 76 of the caliper assembly 32. ~s a result braking torque developed by the outer brake shoe 38 is transmitted to the caliper assembly 32 which in turn transmi.ts braking torque to the axially ex-tending flange 26 via an abutment interface between the caliper assembly and the axially extending flange at 77. Consequently, substantially no braking torque i.s transmitted to the pins 28 and 30, even though the resilient bushings 50, 81, and 84 may be deformed during braking. A pair of radially outwardly extending ears at 78 and 80 on the friction tm/~ 4-i 1 ~3~09 element 38 carry the resilient bushings 81 and 84 within openings 83 and 85 for receiving the pins 28 and 30, respectively. The resilient bushings form a spacing between the pin and the wall of the openings 83 to permit sligh~ movement of the brake shoe 38 without transferring any torque to the pin portion 62. The opening on the bushing 81 or the open-ing on the bushing 84, or both"ray be elliptical to accommodate manu-facturing eccentricities between the pins 28 and 30. The outer brake shoe 38 releasably couples to a spring 82 for retaining the outer brake shoe in atutment with the radially inwardly extending leg 76 of the caliper.
If the disc or rotor 40 is rotating in a reverse direction, such as when a vehicle is backing up, the torque member 12 includes a second abutment interface at 79 with the caliper assembly 32 to absorb braking torque generated through the caliper assembly during braking.
The abutment interface at 77 is partially formed by at least two pro-jections on the axially extending flange 26 while the abutment interface at 79 is formed by only one projection on the arm 20 as more braking torque will be developed during forward rotation of the disc 40 than reverse rotation of the latter.
In accordance with the invention, it is seen, viewing Figure 2, that the caliper assembly 32 forms a single sliding connection with each pin 28 and 30 via the radially extending flanges 42 and 44 and the pins 28 and 30 are spaced from the caliper 32 on the axially outer side of the torque member 12. Consequently, the transverse width A, of the caliper 32 is substantially uniform from the radially extending flanges 42 and 44, but not inclusive thereof, to and including the radially inwardly extending leg 76. In other words, the c21 iper transverse width A i5 less than the transverse` distance between the pins 28 and 30, provided the transverse width A is rrRasured axially outside of the flanges 42 and 4l~.
i ~ 63209 In addition, the ou-ter friction elemen-t 38 includes openings 83 and 85 for receiving the pins 28 and 30. These openings are provided in the radially outwardly extending ears 78 and 80 on the outer friction element, so that the concentricity between the openings 46, 48 and 83, 85 respectively, is maintained in the absence oE openings being required in the caliper assembly leg 76. In contrast thereto, the prior art generally requires two sliding connections between the caliper and each pin so that two openings on the caliper assembly are required to be concentric for receiving the pin.
~s a result, the disc brake assembly of the present invention is believed to be easier to manufacture with respect to accommodating manufacturing tolerances, in comparison to the prior art pin slider disc brakes.
The thermo-plastic sleeve and the resilient bushing cooperates with the thermo-plastic sleeve to Eorm a sliding connection between the caliper and pin -to accommodate axial movement of the caliper as the hydraulic actuator is operated to urge the pair of brake shoes into frictional engagement with the rotor. The disc brake 10 operates in a conventional manner to retard rotation of the rotor.
The arrangement including the bushing in combination with the sleeve is also described and is claimed in applicant's above-identified parent application Serial No. 333,993.
The foregoing description is directed to the left pin 28 and flange 42; however, the right pin 30 may carry a thermo-plastic sleeve which cooperates with a resilient bushing on the flange 44 in the same manner as the sleevç and bushing, 52 and 50, respectively.
Many variations of the present invention are feasible by one skilled in the art and, as such, these varia-tions are intended to fall wi-thin -the scope of the appended claims.

Figure 1 i.s an end view of a disc brake assembly;
Figure 2 is a top view of the disc brake assembly o~ Figure 1 with the portion along line 2-2 of Figure 1 being cu-t away; and Figure 3 is a cross-sec~ional vie~ of Figure 1 taken along line 3-3 of Figure 1.
DETAILED DESCRIPTION
A disc brake assembly 10 includes a tor~ue member 12 which is secured to a non-rotatable portion of a frame 14 via bol.ts 16. The torque member is substantially U-shaped to form a pair of radially extending arms 18 and 20. The arms form bores at 22 and 24 and the left arm 18 includes an axially extending flange 26; however, it is possible to also provide an axially extending flange for the right arm 20. The bore 22 is disposed in the flange 26 to receive a pin 28 while the bore 2~ receives a pin 30. A caliper assembly 32 is slidably carried by the pins and a hydraulic actuator 34 carried by the caliper assembly 32 cooperates with a pair of brake shoes 36 and 38 to urge the latter into fricti.onal engagement with a disc or rotor 40.
Turning to Figure 2, the caliper assembly 32 ~m/~ -2-~ 1 ~3~09 ~ cludes a pair of .radially extendiny flanges a-t 42 and 44 which form openings 46 and 48. Viewing the lef t radial - flange 42, as the right flange 4'1 is constructed similarly, the opening 46 receives a resilien-t bushing 50, such as a rubber grommet, and the pin 28 may op-tionally carry a thermo-plastic sleeve 52 to enhance sliding with the resilien-t bushing 50. The thermo-plastic sleeve 52 extends through an opening on the resilient bushing 50 and cooperates with the latter to form a sliding connection between the pin 10 28 and -the caliper 32.
The pin 28 forms a head 54 and an adjoi.ning recess 56 to receive lhe-the:rmo-plastic sleeve 52. A threaded portion of the pin 28 at 58 is engageable with a threaded portion of the bore 22 at 60. In addition, a second portion 62 of the pin 28 forms a close fit with a second por-tion 6~ of the bore 22. A small clearance between portions 62 and 64 is provided to accommodate manufacturing tolerances upon insertion of the pin 28 i nto the bore 22. A shoulder 55 on the pin 28 is engageable wi th the torque member arm 20 18 when the pin 28 is threadably engaged with the bore at 60. The shoulder 55 separates the recess 56 from -the torque member so that the thermo-plastic sleeve 52 is always spaced f rom the torque member . Therefore, the thermo-plastic sleeve is not subjected to compressive axial loading when the pin is attached to the torque member. As shown in Figure 2, the inner diameter of bushing 50 is greater than the diameter of the shoulder 55 so that the bushing 50 is free to slide on the pin 62 between the head 54 and the torque member arm 18.
The .inner brake shoe 36 includes a backing plate 66 which fits within the opening formed by the U-shaped torque member ' 2. Consequen-tly, braking -torque developed -t ~n/, (,; j ~ 3 -- ~ 1 63209 ~y the inner brake shoe 36 is -transmitted directly -to the torque member 12.

The outer brake shoe 38 also includes a backing plate 70 which is formed with projections 72. The projections extend into apertures 74 which are provided on a radially inwardly ex-tending leg 76 of the caliper assembly 32. The projections extend into apertures 74 which are provided on a radially inwardly extending ]eg 76 of the caliper assembly 32. ~s a result braking torque developed by the outer brake shoe 38 is transmitted to the caliper assembly 32 which in turn transmi.ts braking torque to the axially ex-tending flange 26 via an abutment interface between the caliper assembly and the axially extending flange at 77. Consequently, substantially no braking torque i.s transmitted to the pins 28 and 30, even though the resilient bushings 50, 81, and 84 may be deformed during braking. A pair of radially outwardly extending ears at 78 and 80 on the friction tm/~ 4-i 1 ~3~09 element 38 carry the resilient bushings 81 and 84 within openings 83 and 85 for receiving the pins 28 and 30, respectively. The resilient bushings form a spacing between the pin and the wall of the openings 83 to permit sligh~ movement of the brake shoe 38 without transferring any torque to the pin portion 62. The opening on the bushing 81 or the open-ing on the bushing 84, or both"ray be elliptical to accommodate manu-facturing eccentricities between the pins 28 and 30. The outer brake shoe 38 releasably couples to a spring 82 for retaining the outer brake shoe in atutment with the radially inwardly extending leg 76 of the caliper.
If the disc or rotor 40 is rotating in a reverse direction, such as when a vehicle is backing up, the torque member 12 includes a second abutment interface at 79 with the caliper assembly 32 to absorb braking torque generated through the caliper assembly during braking.
The abutment interface at 77 is partially formed by at least two pro-jections on the axially extending flange 26 while the abutment interface at 79 is formed by only one projection on the arm 20 as more braking torque will be developed during forward rotation of the disc 40 than reverse rotation of the latter.

Consequently, the transverse width A, of the caliper 32 is substantially uniform from the radially extending flanges 42 and 44, but not inclusive thereof, to and including the radially inwardly extending leg 76. In other words, the c21 iper transverse width A i5 less than the transverse` distance between the pins 28 and 30, provided the transverse width A is rrRasured axially outside of the flanges 42 and 4l~.

These openings are provided in the radially outwardly extending ears 78 and 80 on the outer friction element, so that the concentricity between the openings 46, 48 and 83, 85 respectively, is maintained in the absence oE openings being required in the caliper assembly leg 76.
