Technical Field

The invention relates to the field of automobile parts, in particular to a plate spring seat.

Background

The plate spring seat belongs to a part of automobile parts and is mainly used for mounting and fixing a plate spring and an axle. The difference of material hardness between the plate spring and the plate spring seat and between the axle and the plate spring is large, the plate spring is in friction contact for a long time, and the plate spring is twisted to rub the plate spring seat particularly when the road condition is poor and the vehicle turns, so that the abnormal abrasion of the plate spring seat is caused for a long time. The unreasonable design of the plate spring seat can lead the plate spring seat to be unreasonable in stress, and the plate spring seat is cracked from the stress concentration part and can be broken after long-time movement. The connection between the current axle plate spring seat and other parts of an automobile is unstable, and after the automobile is used for a period of time, the connection part is easy to shake or even fall off.

Disclosure of Invention

The invention provides a plate spring seat, and provides an axle plate spring seat which is reasonable in structure and convenient to use, can be combined with automobile parts more reasonably, can be stably connected with connecting pieces on two sides, and prolongs the service life.

The technical purpose of the invention is realized by the following technical scheme: the plate spring seat comprises a square connecting plate, wherein arc-shaped bulges which horizontally protrude outwards are arranged on the same side of a group of opposite sides of the connecting plate respectively, a penetrating bolt connecting hole is formed in the center of each arc-shaped bulge, and a first butt joint part for butt joint of round steel pipes is further arranged on the connecting plate.

Preferably, the first butt joint portion includes an inner protruding strip and an outer protruding strip, the inner protruding strip is a protruding strip extending outward from the surface of the connecting plate between the arc-shaped protrusions on both sides, and the outer protruding strip is a protruding strip extending outward from the surface of the edge of the connecting plate on the side far away from the inner protruding strip.

Preferably, the first butt joint portion further includes a first butt surface, and the first butt surface is an arc-shaped curved surface extending downward from the upper edges of the inner convex strip and the outer convex strip opposite surface and opposite to each other to be connected.

Preferably, the connecting plate is further provided with a second butting part for butting the shock absorber.

Preferably, the second docking portion is located on the reverse side of the connecting plate, and the second docking portion is a protruding strip protruding outwards from two side edges of the connecting plate.

Preferably, a middle groove is further formed in the second docking portion, and the middle groove is a groove recessed inward from a convex surface of the second docking portion.

Preferably, the first contact surface further includes a resistance portion for buffering an impact of the circular steel pipe.

Preferably, the resisting part is a semicircular cylinder with an upward opening, and the resisting part is connected to the surface of the first abutting surface through a spring.

Preferably, the elastic force resisting part comprises double-side protruding plates, plate middle transverse grooves and frame groove rods, the double-side protruding plates are equal-height circular ring surfaces extending upwards from edges of two sides of the first binding surface, the plate middle transverse grooves are straight grooves horizontally and reversely sunken from the surfaces of the middle parts of the double-side protruding plates, the frame groove rods are round rods inserted between the plate middle transverse grooves on two sides, and the frame groove rods are connected to the bottom surfaces of the plate middle transverse grooves through springs.

Preferably, the rotary groove comprises a rotary blocking part, the rotary blocking part comprises a rotary rod and a blocking convex block, the rotary rod is a straight rod reversely extending from the surface of the middle part of the groove rod, and the blocking convex block is an arc-shaped convex plate extending outwards from the edge of the surface of the blocking part close to the two sides.

In conclusion, the invention has the following beneficial effects: the two-side connection member, particularly, the circular steel pipe and the shock absorber can be stably connected.
