Two-way brake actuator output force measurement calibration device

The invention provides a two-way brake actuator output force measurement calibration device and relates to the field of design of brake actuators. The device comprises a brake actuator, a support sleeve, two ball cap assembles, two S-shaped load cells, four guide strips and a base; the base is of a horizontally placed platy structure; the support sleeve is vertically and fixedly mounted at the center of the upper surface of the base in the axial direction; every two guide strips serve as a group, and the four guide strips are symmetrically mounted on both sides of the support sleeve and fixedly mounted on the upper surface of the base; the two S-shaped load cells are symmetrically disposed on both sides of the support sleeve, and each S-shaped load cell is sandwiched between the two corresponding guide strips in the corresponding guide strip group; the two ball cap assemblies are fixedly mounted on the tops of the two S-type load cells respectively; the brake actuator is mounted on thetop of the support sleev
