The middle part is provided with bolt hole II at least 3；
The bottom is ∩ shapes, and ∩ shapes bottom both ends, which are provided with, is used for the pin-and-hole be hinged with plate spring lifting lug, preceding spring.
Preferably, the top is vertical | shape, | the both ends of shape are respectively provided with 1 bolt hole I, and are set between 2 bolt hole I
There is I-beam reinforcement.
Preferably, the middle part is L-shaped, provided with the 5 bolt hole IIs vertical in the horizontal direction with the bolt hole I,
The bolt hole II includes 3 stay bolt holes and 2 lag bolt holes, and the rectangular Triangle-Profile in 3 stay bolt holes is described
2 lag bolt hole positions are outside the right angled triangle.Further, between the stay bolt hole, stay bolt hole and bottom
Between with box reinforcement connect；2 lag bolts are connected with the stiffener plate extended laterally.
Preferably, the pin-and-hole of bottom 2 trend is parallel with the bolt hole II, and the bottom is additionally provided with longitudinally reinforced
Muscle, the span of ∩ shapes are more than the thickness at middle part.
Preferably, bolt hole I and bolt hole the II oral areas are equipped with boss.
After above technical scheme, the multifunction board spring bracket has the advantages that：
1. the transition for providing leaf spring and vehicle frame connects, the transmission of longitudinal force, vertical force and torque is realized, is ensured
The normally travel of automobile；
2. playing a part of one to form a connecting link, the connects bearing of leaf spring is served not only as, while also serves as steering room back suspension
The connects bearing put, it occupies little space, and bulk strength is reliable, solves the risk of old stent failure.
3. the utility model only with vehicle frame side fastening, is connected so as to avoid with vehicle frame lower aerofoil, vehicle frame company is enhanced
The structural strength at place is connect, farthest reduces the stress concentration at vehicle frame.
4. the utility model is compact-sized, integral arrangement space is small；It is convenient to assemble, convenient disassembly, is easy to safeguard.
5. the utility model is designed reasonably, delicate structure, and cost of manufacture is greatly reduced than before, is adapted to the marketization large quantities of
Amount production.
