[0023] Reference Figures 1-3 This utility model provides an embodiment of a heavy-duty vehicle suspension leaf spring that is easy to install. It includes a leaf spring body 1, a fixing block 2 fixedly connected to the bottom side of the leaf spring body 1, an L-shaped fixing bracket 6 fixedly connected to the bottom side of the fixing block 2, and a pin 10 fixedly connected to the rear top of the L-shaped fixing bracket 7. Pins 12 are fixedly connected to the bottom ends of the L-shaped fixing bracket 6 and the L-shaped fixing bracket 7 on adjacent sides. Positioning grooves are provided on the bottom ends of the L-shaped fixing bracket 6 and the L-shaped fixing bracket 7 on opposite sides. Pins 12 are disposed inside the positioning grooves. Insertion points are formed on the outer walls of the pins 12, the L-shaped fixing bracket 6, and the L-shaped fixing bracket 7. The slot, the inside of the insertion slot is provided with an insertion shaft 11 for fixing between L-shaped fixing bracket 1 6 and L-shaped fixing bracket 2 7. The cover plate 8 is rotatably connected to the outer wall of L-shaped fixing bracket 1 6 and L-shaped fixing bracket 2 7. The outer wall of the cover plate 8 is fixedly connected with a semi-circular locking block 13. The outer walls of the two semi-circular locking blocks 13 are threadedly connected with a lock shell 9. The insertion shaft 10 is located inside the top of L-shaped fixing bracket 1 6. The outer wall of the fixing block 2 is fixedly connected with a connecting shaft 4. The outer wall of the steel leaf spring body 1 is fixedly connected with a connecting block 3. The top of the connecting shaft 4 is threadedly connected with a nut 5. The outer wall of the connecting shaft 4 is located on the inner circumference of the connecting block 3. The nut 5 is located on the top side of the connecting block 3.

[0024] Specifically, first, the connecting block 3 is fitted onto the outer wall of the connecting shaft 4, thereby arranging and installing multiple leaf springs on the outer wall of the connecting shaft 4. Then, the connecting block 3 is fixed to the connecting shaft 4 with the nut 5, completing the installation of the fixing block 2 and the connecting block 3. When one of the leaf springs is damaged, the nut 5 can be rotated directly to detach it from the connecting shaft 4. Then, the damaged leaf spring can be removed from the outer wall of the connecting shaft 4, replaced with a new leaf spring, and the nut 5 and connecting shaft 4 can be tightened to replace the damaged leaf spring. When installing the leaf spring body 1 on the axle, the L-shaped fixing bracket 1 6 and the fixing block 2 are fitted onto the axle. Then, the L-shaped fixing bracket 2 7 is inserted into the top of the L-shaped fixing bracket 1 6 through the insert shaft 1 10. Then, the insert shaft 2 12 on the outer wall of the L-shaped fixing bracket 1 6 and the L-shaped fixing bracket 2 7 are inserted into the positioning grooves of the L-shaped fixing bracket 1 6 and the L-shaped fixing bracket 2 7, thereby securing the L-shaped fixing bracket 2 7 to the outer wall of the axle. When L-shaped fixing bracket 16 and L-shaped fixing bracket 27 are fitted together, insert the plug shaft 11 into the plug groove on the outer wall of plug shaft 212, L-shaped fixing bracket 16 and L-shaped fixing bracket 27 to fix L-shaped fixing bracket 16 and L-shaped fixing bracket 27. Then rotate the cover plate 8 to cover the outer wall of plug shaft 11, and then thread the lock shell 9 onto the outer wall of the two semi-circular locking blocks 13 to fix plug shaft 11 between L-shaped fixing bracket 16 and L-shaped fixing bracket 27. Finally, the installation of leaf spring body 1 and axle is achieved, avoiding the impact on the installation efficiency of leaf spring body 1 due to the use of a large number of U-bolts.

[0026] Specifically, the leaf spring body 1 can be mounted on the frame by means of the lug, and the cover plate 8 can prevent the plug shaft 11 from detaching from the L-shaped fixing bracket 6 and the L-shaped fixing bracket 7.

[0027] Working principle: By fitting the connecting block 3 onto the outer wall of the connecting shaft 4, multiple leaf springs are arranged and installed on the outer wall of the connecting shaft 4. The connecting block 3 and the connecting shaft 4 are then fixed together using the nut 5, thus achieving the installation between the fixing block 2 and the connecting block 3. When one of the leaf springs is damaged, it can be directly removed from the connecting shaft 4 by rotating the nut 5, and the damaged leaf spring can be removed from the outer wall of the connecting shaft 4 and replaced with a new leaf spring. When the leaf spring body 1 needs to be installed on the axle, it can be installed by fitting the L-shaped fixing bracket 6 and the fixing block 2 onto the axle, and then... The L-shaped fixing bracket 7 is inserted into the top of the L-shaped fixing bracket 6 via the insertion shaft 10. Then, the insertion shafts 12 on the outer walls of the L-shaped fixing bracket 6 and the L-shaped fixing bracket 7 are inserted into the positioning grooves of the L-shaped fixing bracket 6 and the L-shaped fixing bracket 7, thereby securing the L-shaped fixing bracket 7 to the outer wall of the axle. The insertion shaft 11 is then inserted into the insertion grooves on the outer walls of the insertion shaft 12, the L-shaped fixing bracket 6 and the L-shaped fixing bracket 7. The cover plate 8 is then placed on the outer wall of the insertion shaft 11. Finally, the outer walls of the two semi-circular locking blocks 13 are threaded onto the lock housing 9, thus completing the installation between the leaf spring body 1 and the axle.
