Abstract:
1. A vertical acceleration compensator for sensing vertical movement of a vehicle wheel relative to a vehicle frame and coupled in fluid communication with a brake fluid reservoir and a fluid-actuated brake mechanism for said vehicle wheel comprising: a first compensation member defining a hollow cavity therewithin coupled in flow communication with said fluid-actuated brake mechanism, a second compensation member that occupies a variable volume brake fluid portion of said hollow cavity, and a movable member coupled to both said vehicle frame and said vehicle wheel and responsive to vertical movement of said vehicle wheel relative to said vehicle frame to reciprocally move one of said first and second compensation members relative to the other of said compensation members to contract said variable volume brake fluid portion of said hollow cavity occupied by said second compensation member when said vehicle wheel moves vertically upwardly relative to said vehicle frame and to expand said variable volume brake fluid portion of said hollow cavity occupied by said second compensation member when said vehicle wheel moves vertically downwardly relative to said vehicle frame.
