Abstract

A disc brake for automobiles and trucks having a large area for annular contact wherein the vehicle has a wheel with a hub journaled to an axle, the disc brake including a housing mounted to the axle and a disc rotor mounted to the hub of the wheel. The disc rotor is ventilated and has opposed annular friction surfaces. The housing includes a first annular wall with brake linings adapted to engage one of the friction surfaces of the disc rotor. An air operated bellows moves the brake shoe axially towards the rotor.

Description

~ 21 9~206-"DISC BRAKE ASSEMBLY"
The present invention relates to disc brakes and more particularly to improvements in large area contact disc brakes for vehicles.
The disc brake of the present invention is a disc brake of the type described in Canadian Patent Applications No. 2,046,370 filed July 6, 1991 and No. 2,110,996 filed June 22, 1992. These patent appli-cations refer to full annular disc brakes for larger lo vehicles such as trucks. The concept of the full annu-lar disc brake is now proposed for automobiles and light trucks and the present invention relates to a structure of a full annular disc brake for such vehicles.
A construction in accordance with the present invention comprises a disc brake assembly for a vehicle wheel wherein the wheel includes a hub journaled to an axle on the vehicle, the disc brake assembly comprises a housing mounted to the vehicle and at least an annu-lar disc within the housing and means mounting the discto the wheel. The disc has at least a first radial planar friction surface and the housing includes a first brake shoe provided adjacent the first planar friction surface of the disc and movable axially towards and away from the first friction surface of the disc for friction engagement therewith and release thereof. Means are provided for restraining the first brake shoe from rotating with the disc. The housing also includes an annular radial wall parallel to the first brake shoe, and an annular fluid expandable blad-der extends between the first brake shoe and the radial wall, whereby upon expansion of the bladder the first brake shoe moves axially to frictionally engage the friction surface of the disc and upon release of the fluid from the expandable bladder, the first brake shoe 2 21 ~206 is to be disengaged from frictional contact with the first frictional surface of the disc.
The features of the present invention can be utilized for large trucks as well.
Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illustration, preferred embodiments thereof, and in which:
Fig. 1 is an exploded fragmentary perspective view of an embodiment of the disc brake in accordance with the present invention;
Fig. 2 is a fragmentary radial cross-section taken through the assembled disc brake;
Fig. 3 is a radial cross-section similar to Fig. 2 but including further elements; and Figs. 4a and 4b are enlarged fragmentary cross-section taken along the same section as Fig. 3 but showing the elements in a different operative position.
nReferring now to the drawings, a disc brake assembly 10 for an automobile is illustrated having a housing in the form of a shell 12. The housing has a cylindrical wall 14 with a corrugated inner surface 16 having valleys 16a and ribs 16b. The housing 12 includes a radial annular wall 18 provided with an annular brake pad lining 20. The ribs 16b are rela-tively flat and represent valleys on the outer sur-face 17.
The cylindrical wall 14 also includes a radial flange 15. A spider 22 includes an annular cylindrical corrugated wall portion 24 which is adapted to fit within the corrugated surface 16 of the wall 14 and is retained by flange 15. That is the ribs 24a of the corrugated surface 24 which will fit in the val-leys 16a of surface 16 while the valleys 24b will cor-respond to the ribs 16b of the housing wall 14. Thus, the housing 12 will be locked against circumferential - 3 - 21 9q 206 ~, .,;
movements relative to the spider 22. The spider 22 a hub portion 26 which can be bolted to a flange oni~n axle (not shown) of the vehicle. The spider 22 also has a radial planar wall portion 28 and a cylindrical flange 30.
An indented detent 70 is provided in the housing wall 14 in order to lock the housing 12 against axial movement relative to the spider 22. The detent 70 protrudes inwardly to engage the spider 22.
The wall 28 is adapted to receive strain sensor 60. These strain sensor may be the type known under Trademark MULTIDYN and described in U.S. Patent No. 5,522,270 issued June 4, 1996 to THOMSON-CSF. The strain sensor 60 can provide valuable information on the braking efficiencies and the wear of the brake shoes.
The strain sensor 60 extends somewhat tangen-tially to the wall 28 and can, therefore, monitor the torque being applied between the hub 26 and the cylin-drical flange 30 of spider 22. With the information which can be obtained from strain sensor 60, the tem-perature of the brakes can be monitored by means of suitable micro processors. For instance, when the brakes are applied, the pressure is known, and if the heat should increase the torque will be reduced.
Increased temperature of the brakes will normally signal brake deterioration or malfunction.
Other criteria can also be determined logi-cally from the known pressure, and the torque informa-tion provided by the strain sensor 60.
An annular disc rotor 32 includes radial planar friction surfaces 34 and 36 and a cylindrical annular hub 38 having an inner corrugated surface 40 with ribs 40a and valleys 40b. A hub member 42 includes a radial wall portion 44 adapted to be mounted to a vehicle wheel and a cylindrical corrugated wall 46. The wall 46 has ribs 46a and valleys 46b which are adapted to fit within the cylindrical wall inner surface 40 of the disc rotor 32. Thus, the rotor 32 will be locked against relative rotational movements with the hub 42.
Since the hub 42 is mounted onto a vehicle wheel the rotor 32 will rotate with the wheel. The disc rotor 32 is ventilated and therefore has radially extending ventilation passages 48 communicating with openings 49 in housing wall 14.
A brake shoe 50 includes brake linings 52 and a backing plate 54. The brake shoe 50 includes a corru-gated peripheral edge 51 engaging the inner surface 16 of the cylindrical wall 14. Thus, the brake shoe 50 can slide axially but is retained against rotational move-ment. An annular bellows 56 is provided between the wall 28 and the backing plate 54. As described in Cana-dian Patent Application 2,110,996, when fluid such as air is fed into the bellows 56 it will expand, moving the brake shoe 50 axially towards the friction surface 36 of disc rotor 32. The disc rotor 32 can also move radially on the hub 42 and the radial surface 34 will come in frictional contact with the brake linings 20.
Thus, when it is necessary to apply the brakes, the bellows 56 is expanded. However, to release the brakes the air is allowed to exhaust from the bellows 56, thereby releasing the axial pressure on the brake shoe 50, allowing the disc rotor 32 to rotate freely within the housing 12.
Referring now to Figs. 3, 4a and 4b, the rolling seals will be described. The rolling seals 62, which are located, in the present invention, on the outer surface 46 of the hub 42, are formed to the contour of the corrugated surface. As shown in Fig. 3, the pair of rolling seals 62 are precompressed when inserted between the hub 42 and the disc rotor 32.
Retainer ring 63 may be provided to hold seal 62a in place. Seal 62b is retained by lip 65 formed in hub 46.
Retainer ring 63 is formed with convexly curved surface 63b to support seal 63a and control th~e deformation of the seal as will be described. The hub 46 is also formed with convexly curved surface 65b to control seal 62b. When the disc rotor 32 slides on the hub 42, as previously described, the rolling seals 62 will deform in the direction of the path of the rotor 32, as seen in Fig. 4b, ~hen it is pushed by the brake shoe 50. When the brake is released, the rolling seals 62 will return to their idle position, as shown in Fig. 4a, thereby drawing the rotor 32 away from the brake pad 20.
In the same manner, rolling seals 64 and 66, which are located on the flange 30 and housing wall 14 respectively, engage the brake shoe 50, and will act to return the brake shoe 50 away from the friction surface 34 of the disc rotor 32 to eliminate drag of the brakes.
It is noted that the rolling seals 62 could be located on the disc rotor and engaging the hub rather than as set up in the present embodiment.
