Technical Field

[0001] This utility model relates to the field of leaf spring positioning technology, specifically to a novel leaf spring positioning support plate. Background Technology

[0002] Leaf springs are commonly used in wheeled vehicle suspensions. In the most common configuration, the center of the arc provides the location of the axle. Leaf springs are made of long, rounded spring steel with a rectangular cross-section. For very heavy vehicles, leaf springs can be made from multiple leaves stacked together, typically with leaves that gradually shorten.

[0003] According to Chinese Patent CN201920654049.7, a leaf spring positioning device for the bottom of a truck body is disclosed. This application includes a mounting base plate, a slider slidably connected to the lower half of one side of the mounting base plate, a fixing plate provided on the upper half of the mounting base plate, a base provided on the side of the slider facing away from the mounting base plate, a connecting seat provided on the side of the base away from the slider, a positioning plate hinged to the base through the connecting seat, the end of the positioning plate away from the connecting seat rotating and embedding into the fixing plate, and the positioning plate being fixedly connected to the fixing plate by fastening screws, and the slider being fixedly connected to the mounting base plate by fastening screws.

[0028] Example 3;

[0029] like Figure 1-4As shown, the system includes a substrate 1, a baffle 2 on one side of the top of the substrate 1, and a groove 3 on the side of the top of the substrate 1 away from the baffle 2.

[0030] In practical applications, when positioning and supporting the leaf spring, first rotate the pressure plate 6 upwards, then place the leaf spring on the base plate 1, so that the concave part of the leaf spring fits against the convex part of the pressure block 5. Then rotate the pressure plate 6 downwards, so that the pressure plate 6 presses against the leaf spring. At the same time, the pressure plate 6 drives the limiting block 8 to lock onto the convex part of the leaf spring. Then, the operator pushes the slider 4 to move, the slider 4 drives the pressure block 5 to move, and the pressure block 5 drives the leaf spring to move closer to the baffle 2 until the convex part of the leaf spring is pressed against the baffle 2. At the same time, the limiting block 8 moves into the limiting groove 9 on the baffle 2. Then, tighten the locking bolt 12 to fix the slider 4 to the base plate 1, and tighten the locking bolt 24 to limit and fix the limiting block 8 to the baffle 2.
