Description
_ 9682/95093 2 1 8 7 4 8 8 BRAKE UNIT FOR AN AUTOMATIC TRANSMISSION SYSTEM
TECHNICAL FIELD
This invention relates to a brake unit for an automatic transmission system. More specificaily, the invention is directed to a brake unit including a brake drum and a brake band in which a friction lining is positioned on the brake drum.
BACKGROUND OF THE INVENTION
Prior art brake bands consist of a steel carrier with a brake lining applied thereon. In order to ensure proper function, the brake drum surface that comes into contact with the lining is made of processed steel or gray cast iron.
In prior art brake units, the brake drum serves to accommodate a multiple disk clutch. Due to the previously described material requirements for ensuring the proper function of the brake band, the brake unit is relatively heavy. This results in performance problems with vehicles in which the brake units have been installed. It also results in relatively expensive and complicated manufacturing processes for the brake units. For these reasons, there is a need for a relatively lightweight brake unit. The present invention satisfies this need.
The present invention is directed to a brake unit in which a friction lining is positioned on a substantially cylindrical brake drum that is comprised of a lightweight metal alloy and the brake band is comprised of steel. Accordingly, the rotating surface of the friction lining cooperates with the steel surface of the brake band to ensure proper function of the brake unit.
The manufacture of the brake drums with a lightweight metal alloy provides certain weight and manufacturing advantages as compared to the prior art casting, forging, pressing, or deep-drawn processes that are carried out on steel blanks or gray cast iron. As previously mentioned, the prior art brake units are relatively expensive and involve time consuming manufacturing processes. The lightweight metal alloy brake drum of the present invention is less difficult to manufacture, and therefore less expensive. Further advantages include a reduction in fuel consumption in the vehicle in which the present invention is installed due to the decrease in weight of the brake unit. The present invention has also been found to reduce noises and vibrations originating with the brake unit. Finally, the present invention provides a unique way of lubricating the brake unit as described below.
SUMMARY OF THE INVENTION
The present invention is directed to a brake unit having a brake drum that includes a generally cylindrical outer surface. A friction lining having a generally cylindrical configuration corresponding to the outer surface of the brake drum is positioned on the outer surface of the brake drum. A brake band having a generally cylindrical interior surface corresponding to the outer surface of the brake drum engages the friction lining.
It is the primary object of the present invention to provide a brake unit having a lightweight brake drum with a friction lining applied thereto and a brake band adjacent the friction lining.
An important object of the present invention is to provide a brake unit wherein the outer surface of the brake drum defines a plurality of bores arranged in a predetermined pattern for allowing flow of a fluid lubricant to the friction lining.
An important object of the present invention is to provide a brake unit having a friction lining that includes a plurality of grooves arranged in a predetermined pattern for channeling flow of a fluid lubricant.
Other objects and advantages of the present invention shall become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.
- - 21 874~8 BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a side view of a brake unit according to the present invention;
Fig. 2 is a cross-sectional view taken through line 2-2 of Fig. 1;
and Fig. 3 is a plan view of a portion of a friction lining according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments and best mode of the present invention will now be described in detail with reference being made to the drawings. The brake unit of the present invention is indicated generally in the drawings by the reference number "10n.
Referring to Fig. 1, the brake unit 10 generally includes a brake drum 12, a friction iining 14 positioned thereon and a brake band 16. As shown in Fig. 2, the brake drum 12 includes a generally cylindrical outer surface 18 and an opposed generally cylindrical inner surface 20. A
plurality of bores 22 is defined by the brake drum 12 between the outer surface 18 and the inner surface 20. The bores 22 are arranged in a predetermined pattern. The bores 22 allow a fluid lubricant, such as automatic transmission fluid (ATF~, to flow from the interior of the brake drum 12 to the outer surface 18. As described below, the bores 22 convey the ATF from the interior of the brake drum 12 to the friction lining 14 in order to ensure proper function of the lining.
Still referring to Fig. 2, the inner surface 20 of the brake drum 12 includes a plurality of inwardly projecting beads 24. The brake unit 10 includes a gear mechanism 26 having a disk pack 28, an end disk 30 and a locking ring 32. The beads 24 engage the locking ring 32. The locking ring 32 and the beads 24 axially limit the possible displacement of the end disk 30 that supports the outer surface 18 of the brake drum 12.
~ 9682/95093 2 ~ 8 7 4 8 8 The end disk 30 supports the outer surface 18 while a load is applied to the brake band 16.
Referring to Fig. 1, the brake drum 12 can be comprised of a variety of shapes, with a conical shape being preferred. The brake drum 12 can be made from a variety of materials, with a lightweight metal alloy being preferred.
Referring to Figs. 1 and 2, the friction lining 14 of the brake unit 10 includes a generally cylindrical configuration corresponding to the outer surface 18 of the brake drum 12. The friction lining 14 is positioned on the entire circumference of the outer surface 18. The friction lining 14 is positioned on the outer surface 18 by the application of a heat source that adheres the lining to the outer surface.
Referring to Fig. 3, the friction lining 14 includes a plurality of grooves 34 arranged in a predetermined pattern. The grooves 34 are in communication with the bores 22 defined by the brake drum 12. When the brake unit 10 is in operation, a fluid lubricant, such as ATF, is conveyed from the interior of the brake drum 12 through the bores 22 to the grooves 34 of the friction lining 14. The predetermined pattern of the grooves 34 allows the ATF to be conveyed to the friction lining 14 in a metered and directional fashion. The conveyance of the ATF allows for the discharge of heat from the brake unit 10 and controls the thermal expansion of the brake drum 12. The different thermal expansions of the lightweight metal brake drum 12 and the gear mechanism 26 situated within the brake drum are controlled by the predetermined pattern of the bores 22 as well as the predetermined pattern of the grooves 34 of the friction lining 14. Therefore, a larger quantity of bores 22 or larger bores 22 and grooves 34 need to be provided toward the end of the brake drum 12. A combination of these measures might also be necessary depending on the types of materials used in the manufacture of the brake drum 12, the friction lining 14 and the brake band 16.
_ 9682/95093 21 137488 An example of a predetermined pattern for the grooves 34 is shown in Fig. 3. The predetermined pattern includes a central groove 36, a perpendicular groove 38 and a diagonal groove 40. In the embodiment shown in Fig. 3, the grooves 38 and 40 originate at the central groove 36 and terminate at first and second projecting parts 42 and 44, respectively. The first and second projecting parts 42 and 44 "close" the grooves 36 and 38 to concentrate the ATF in the central region of the friction lining 14. The first and second projecting parts 42 and 44 are removably connected to the friction lining 14 by a plurality of perforations 46. When the first and second projecting parts 42 and 44 are removed from the friction lining 14, the grooves 38 and 40 become "open" so that ATF can be conveyed from the central portion of the lining to the exterior of the lining.
The friction lining 14 can be made from a variety of materials. It has been found that paper is especially suitable in the present invention.
Referring to Figs.1 and 2, the brake unit 10 includes a brake band 16 having a generally cylindrical interior surface 50 that corresponds to the outer surface 18 of the brake drum 12. The interior surface 50 does not contain any projecting rivets or other projections and is therefore smooth. The interior surface 50 of the brake band 16 engages the friction lining 14 positioned on the outer surface 18 of the brake drum 12. As shown in Fig. 1, the brake band 16 includes a first end 52 and a second end 54. Each of the ends 52 and 54 includes a bracket 56 for receiving, for example, a reaction pin 58 and an apply piston 60, respectively.
The brake band 16 can be made of a variety of materials, with steel being preferred. Examples of suitable brake bands are disclosed in U.S. Patent Nos. 5,078,237 and 5,348,040, the teachings of which are incorporated herein by reference.
The above detailed description of the present invention is given for explanatory purposes. It will be apparent to those skilled in the art that 21 ~7483 numerous changes and modifications can be made without departing from the scope of the invention. Accordingly, the whole of the foregoing description is to be construed in an illustrative and not a limitative sense, the scope of the invention being defined solely by the appended claims.
