Abstract
Abstract There is disclosed a disc brake system, especially for motor vehicles, in which a housing supporting the brake disc is connected with the wheel hub and the brake shoes are mounted to be axially displacable relative to the wheel axle. According to an important aspect of the invention, the brake disc is detachably secured to the marginal edge or portion of the housing, which preferably possesses a substantially bell-shaped configuration, and the support for the brake shoes surrounds the wheel axle in the form of a sliding sleeve.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
A disc brake system for a wheel having a wheel rim and a wheel axle, especially for motor vehicles, comprising cooperating brake disc means and a pair of movable brake shoe means, housing means, means for fixedly connecting said housing means with the wheel rim of the wheel to be braked, said housing means having an outer surface including a marginal edge portion for the attachment of said brake disc means for revolving movement between said pair of brake shoe means, means for detachably securing said brake disc means at its peripheral region with said marginal edge portion of said housing means, a substantially cylindrical guide sleeve fixedly carried directly by said wheel axle, a one-piece slideable support means surrounding said guide sleeve in spaced sliding relationship with respect thereto for mounting said pair of brake shoe means for axial displacement relative to said guide sleeve, means for securing said slideable support means for the pair of brake shoe means so as to be nonrotatable relative to said guide sleeve, said guide sleeve, said one-piece slideable support means and said brake disC means all being mounted within said wheel rim.
Claim 2
Dependent Claim
190 words
A disc brake system for a wheel having a wheel rim and a wheel axle, especially for motor vehicles, comprising cooperating brake disc means and a pair of movable brake shoe means, housing means, means for fixedly connecting said housing means with the wheel rim of the wheel to be braked, said housing means having an outer surface including a marginal edge portion for the attachment of said brake disc means for revolving movement between said pair of brake shoe means, means for detachably securing said brake disc means at its peripheral region with said marginal edge portion of said housing means, a substantially cylindrical guide sleeve fixedly carried directly by said wheel axle, a one-piece slideable support means surrounding said guide sleeve in spaced sliding relationship with respect thereto for mounting said pair of brake shoe means for axial displacement relative to said guide sleeve, means for securing said slideable support means for the pair of brake shoe means so as to be nonrotatable relative to said guide sleeve, said guide sleeve, said one-piece slideable support means and said brake disC means all being mounted within said wheel rim.
Claim 3
Dependent Claim
176 words
A disc brake system for a wheel having a wheel hub and a wheel axle, especially for motor vehicles, comprising cooperating brake disc means and a pair of brake shoe means, housing means connected with the wheel hub of the wheel to be braked, said housing means having an outer surface including a marginal edge portion provided thereat with spaced recesses defining therebetween column means for the attachment of said brake disc means for revolving movement between said pair of brake shoe means, means for detachably securing said brake disc means at its peripheral region with said column means of said housing means, support means for mounting said pair of brake shoe means for axial displacement relative to the wheel axle, said support means enclosing said wheel axle and a substantially cylindrical guide sleeve and defining a one-piece sliding sleeve member, a guide sleeve provided for said wheel axle within said one-piece sliding sleeve member, a key-keyway guide arrangement for nonrotatably securing said support means for said pair of brake shoe means at said guide sleeve.
Claim 4
Dependent Claim
176 words
A disc brake system for a wheel having a wheel hub and a wheel axle, especially for motor vehicles, comprising cooperating brake disc means and a pair of brake shoe means, housing means connected with the wheel hub of the wheel to be braked, said housing means having an outer surface including a marginal edge portion provided thereat with spaced recesses defining therebetween column means for the attachment of said brake disc means for revolving movement between said pair of brake shoe means, means for detachably securing said brake disc means at its peripheral region with said column means of said housing means, support means for mounting said pair of brake shoe means for axial displacement relative to the wheel axle, said support means enclosing said wheel axle and a substantially cylindrical guide sleeve and defining a one-piece sliding sleeve member, a guide sleeve provided for said wheel axle within said one-piece sliding sleeve member, a key-keyway guide arrangement for nonrotatably securing said support means for said pair of brake shoe means at said guide sleeve.
Claim 5
Dependent Claim

Claim 8
Dependent Claim
28 words
A disc brake system as defined in claim 5, wherein the other of said brake shoe means is mounted to be axially displaceable at said brake shoe-support means.
Claim 9
Dependent Claim
32 words
A disc brake system as defined in claim 6, further including means for displacing said one axially displaceable brake shoe means, and a dust-free housing in which said displacing means is mounted.
