Abstract
Abstract In a fluid-operated vehicle brake assembly of the type wherein space considerations prevent the brake actuator from being assembled directly on to the brake torque plate and therefore require the brake actuator to be mounted on some form of extension arm or equivalent member which enables it to be positioned remotely from the torque plate, the invention provides a brake actuator mounting on a bracket rigidly connected to a vehicle axle assembly and a self-aligning tubular member acting between the bracket and the torque plate to contain the forces acting between them during a braking operation, the tubular member also acting as a housing for an actuator rod extending from the actuator and for a brake expander rod extending from a brake expander mounted on the torque plate the two rods being coupled together within the tubular member for enabling brakeactuating forces to be transmitted from the brake actuator to the brake expander.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A fluid-operated vehicle brake assembly comprising a vehicle brake including a fixed torque plate located on a vehicle axle assembly, a bracket member rigidly connected to said axle assembly, a tubular member extending between said bracket and said torque plate, a self-aligning bearing at each end of said tubular member to render said tubular member self-aligning between said bracket and torque plaTe, a seat member for receiving and locating the bearing at one end of said tubular member, said seat member being fixed to said torque plate, a seat on said bracket for the bearing at the other end of said tubular members, an actuator rod extending from said actuator through said bracket and and into one end of the tubular member, and a brake expander rod passing through said torque plate into the other end of said tubular member and being coupled to said actuator rod within said tubular member, said tubular member acting between said seats to contain the forces acting between said bracket and said torque plate during a braking operation.
Claim 2
Dependent Claim
174 words
A fluid-operated vehicle brake assembly comprising a vehicle brake including a fixed torque plate located on a vehicle axle assembly, a bracket member rigidly connected to said axle assembly, a tubular member extending between said bracket and said torque plate, a self-aligning bearing at each end of said tubular member to render said tubular member self-aligning between said bracket and torque plaTe, a seat member for receiving and locating the bearing at one end of said tubular member, said seat member being fixed to said torque plate, a seat on said bracket for the bearing at the other end of said tubular members, an actuator rod extending from said actuator through said bracket and and into one end of the tubular member, and a brake expander rod passing through said torque plate into the other end of said tubular member and being coupled to said actuator rod within said tubular member, said tubular member acting between said seats to contain the forces acting between said bracket and said torque plate during a braking operation.
Claim 3
Dependent Claim
44 words
A brake assembly as set forth in claim 1, wherein one of the self-aligning bearings on the tubular member is a separate bearing member located on said tubular member, the other bearing being integrally formed on said tubular member at the respective end thereof.
Claim 4
Dependent Claim
65 words
A brake assembly as set forth in claim 1, further comprising a sleeve portion on said bracket member, said sleeve portion being rigidly mounted over an axle tube of said axle assembly, and a generally radially directed arm extending from said sleeve and formed with the seat for the self-aligning bearing at said other end of said tubular member, said seat having a part-spherical configuration.
Claim 5
Dependent Claim
22 words
A brake assembly as set forth in claim 2, wherein said separate bearing member is in threaded engagement with said tubular member.
Claim 6
Dependent Claim
29 words
A brake assembly as set forth in claim 2, wherein said separate bearing member additionally serves to secure the adjoining end of the tubular member within the bracket member.
Claim 7
Dependent Claim
51 words
A brake assembly as set forth in claim 3, wherein said arm is formed with a part-spherical depression defining said part-spherical seat and the adjoining end of said tubular member passes through said arm to engage the self-aligning bearing at said adjoining end of said tubular member with said part-spherical seat.
Claim 8
Dependent Claim
74 words
A brake assembly as set forth in claim 3, said seat member being apertured to receive the end of the tubular member remote from the bracket member, said remote end of said tubular member being opened out to define said bearing and said bearing having a part-spherical configuration; and wherein said seat member is internally shaped to define a part-spherical seat surface complementary to said bearing and circumscribing the aperture in said seat member.
Claim 9
Dependent Claim
65 words
A brake assembly as set forth in claim 3, wherein the bearing located at the end of the tubular member adjoining the bracket in a separate bearing member and the radial arm of said bracket is centrally thickened, the thickened portion of said arm being formed with a bearing seat, said separate bearing member having an end complementary to and retained in said bearing seat.
Claim 10
Dependent Claim
46 words
A brake assembly as set forth in claim 8, wherein a convex bearing formed at the end of the tubular member remote from said separate bearing member is retained in a complementary seat of said seat member by a threaded ring engaged in said seat member.
