Abstract
A slack adjuster assembly for use in a heavy-duty vehicle drum brake system, the slack adjuster assembly comprising a slack adjuster, an inboard sealing assembly, and a sensor arrangement. The slack adjuster is mounted on an inboard end of a camshaft of the drum brake system. The inboard sealing assembly sealingly engages with an inboard side of the slack adjuster. The sensor arrangement measures rotation of the camshaft and is at least partially disposed within the inboard sealing assembly to protect the sensor arrangement from impact damage, water, chemicals, and debris.
Claims21
A slack adjuster assembly for use in a heavy-duty vehicle drum brake system, the slack adjuster assembly comprising:
- a slack adjuster mounted on an inboard end of a camshaft of said drum brake system;
- an inboard sealing assembly sealingly engaged with the exterior surface of an inboard side of a body of said slack adjuster;
- a sensor arrangement for measuring the rotation of said camshaft, said sensor arrangement being at least partially disposed within said inboard sealing assembly;
- whereby said inboard sealing assembly protects said sensor arrangement from impact damage, water, chemicals, and debris.
A slack adjuster assembly for use in a heavy-duty vehicle drum brake system, the slack adjuster assembly comprising:
- a slack adjuster mounted on an inboard end of a camshaft of said drum brake system;
- an inboard sealing assembly sealingly engaged with the exterior surface of an inboard side of a body of said slack adjuster, said inboard sealing assembly having a cover and a seal, said seal being at least partially disposed within said cover to protect the seal from impacts, said cover engaging with said inboard side of said slack adjuster;
