Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

As shown in fig. 1 to 3, the flanged outer tube bushing provided by the utility model comprises an outer tube 10, an inner tube 12 and a main spring 14 arranged between the outer tube 10 and the inner tube 12, wherein two hollow holes 16 penetrating through the radial direction of the main spring 14 are symmetrically formed in the main spring 14, the horizontal section of each hollow hole 16 is arc-shaped, the area of the sections at two ends of each hollow hole 16 is larger than that of the section in the middle, the main spring 14 is made of rubber, vulcanization treatment is adopted between the main spring 14 and the outer tube 10, the hollow holes 16 are formed in the radial direction of the main spring 14, the rigidity difference in the radial hollow solid direction is easy to adjust, the flange 18 of the outer tube 10 extends outwards, a plurality of bumps 20 are arranged on the upper surface of the flange 18 in an array, a press-fit area 22 is formed between the bumps 20, the main spring 14 is made of rubber and extends to cover the press-fit area 22, the upper surface of the flange 18 of the outer tube 10 is uniformly covered with rubber, the rubber is attached above the edge of the outer tube 10, and the fixing capacity of the flange 18 can be increased when the bushing is stressed when the bushing is mounted, and falling is prevented.

The middle part of the collision block 20 is higher than the two ends of the collision block, the bottom of the end face and the side face of the collision block 20 are provided with convex points 22 for reducing the contact surface, and the convex points 22 on the collision block 20 reduce the contact between the rubber plane and the vehicle body, thereby reducing friction and noise.

The inner tube 12 is made of aluminum, the outer tube 10 is made of iron, and the surface treatment is performed by a low-temperature electrophoresis process. The cost is lower compared with zinc-nickel material.

The flange 18 on the outer tube 10 extends outwards to be 14mm to 16mm, and the flange 18 extends to be long, so that a large press-fit area is ensured, and the auxiliary frame is easier to press.

Embodiment two: the difference from the first embodiment is that a metal sheet is inserted into the hollow hole 16 from both ends thereof.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
