Suspension motion charging arrangement

A vehicle suspension arrangement, comprising:

• a mounting member configured to mount to a vehicle frame assembly;
• a trailing arm having a first end pivotably coupled to the mounting member and a second end;
• an axle assembly coupled to the second end of the trailing arm such that the second end of the trailing arm travels in a vertical direction between a raised position and a lowered position as the axle assembly moves in a vertical direction;
• an air spring arrangement biasing the second end of the trailing arm from the vehicle frame assembly;
• and
• a charging arrangement having a first portion operably coupled with the second end of the trailing arm such the first portion is fixed for vertical movement with the second end of the trailing arm, and a second portion that is operably coupled with the vehicle frame assembly such that the second portion is fixed for vertical movement with the vehicle frame assembly, wherein the charging arrangement is configured to generate an electrical charge when the first portion of the charging arrangement moves relative to the second portion of the charging arrangement.
