  • Method and means for testing CV driveaxles
    Patent number: 5576496
    Abstract: A test unit is provided for operatively testing CV driveaxles. The test unit has a drive spindle connected to a motor, and a pivotable brake spindle connected to a brake. An axle under test is connected with spindle adaptors to the drive and brake spindles. During a test, the axle under test is rotated by the motor, the brake is engaged to load the axle, and the brake spindle is pivoted to flex at least the outboard CV joints. The test unit is easily adaptable for testing different axles by using spindle adaptors. An accelerometer on the bearing block of the brake spindle detects vibration generated by the axle under test.
