Loading sensing proportioning valve assembly spring tooling

The invention discloses a loading sensing proportioning valve assembly spring tooling, which comprises an installing plate, a support plate and a leaf spring, wherein the installing plate is provided with a first through hole and a connecting plate, the support plate is provided with a second through hole, an attaching plate capable of being tightly attached with the lower surface of a vehicle body bottom plate is arranged on the support plate, the installing plate is fixedly connected with the support plate through the connecting plate, in addition, the installing plate and the support plate are mutually parallel, the space between the installing plate and the support plate is identical to the thickness of a rear axle support frame, the diameter of the first through hole is identical to that of a spring installing screw bolt, the diameter of the second through hole is greater than or equal to the diameter of the spring installing screw bolt, the leaf spring is arranged on the connecting plate in a way of facing the rear axle support frame, and in addition, the axial direction of the leaf spring is vertical to the upper surface of the rear axle support frame. The loading sensing proportioning valve assembly spring tooling disclosed by the invention has the advantages that through the compression of the leaf spring, the tooling is fixedly arranged between the vehicle body bottom plate and the rear axle support frame, and then, the tooling is fixed through the spring installing screw bolt.
