Embodiment 1

[0045] refer to figure 1 with figure 2 , the embodiment of the present application discloses a pin-through ball pin assembly, including a polyurethane ball pin 1 , a ball shell 2 , an elastic sleeve 3 , a sheath 4 , a sealing cover 5 and an elastic ring 6 .

[0046] refer to figure 2 with image 3, The polyurethane ball pin 1 includes a ball 11 , a cylinder 12 and a shaft hole 13 . The cylinder 12 has a cylindrical structure and has two symmetrically arranged on both sides of the sphere 11 ; the sphere 11 and the two cylinders 12 are coaxially arranged. The shaft hole 13 is arranged coaxially with the polyurethane ball pin 1, and penetrates it along the axial direction of the polyurethane ball pin 1 (that is, the shaft hole 13 respectively penetrates the two cylinders 12 and the ball 11 between them in the axial direction. ); The shaft hole 13 is used to accommodate the pin shaft. During use, the operator passes the pin shaft through the shaft passing hole 13 and fixes ...

Embodiment 2

[0071] A pin-through ball pin assembly disclosed in this embodiment and the polyurethane composite material used in the assembly are basically the same as in Example 1, the difference is that the raw material ratio of the polyurethane composite material is different, specifically: 100kg of polyurethane Elastomer, 10kg of vitrified microspheres, 10kg of glass fiber, 12kg of ultra-high molecular weight polyethylene, 7kg of zirconium boride, 25kg of high wear-resistant carbon black, 1kg of molybdenum disulfide, 1kg of polyethylene glycol fat Ester, 1kg of paraffin, 3kg of diisooctyl terephthalate, 1kg of N-isopropyl-N'-phenyl-p-phenylenediamine, 2kg of dicumyl peroxide, 1.2kg of triene Acryl isocyanurate and 0.1 kg of sulfur.

Embodiment 3

[0073] A pin-through ball pin assembly disclosed in this embodiment and the polyurethane composite material used in the assembly are basically the same as in Example 1, the difference is that the raw material ratio of the polyurethane composite material is different, specifically: 100kg of polyurethane Elastomer, 40kg of vitrified microspheres, 15kg of glass fiber, 6kg of ultra-high molecular weight polyethylene, 12kg of zirconium boride, 15kg of high wear-resistant carbon black, 6kg of molybdenum disulfide, 3kg of polyethylene glycol fat Ester, 5kg of paraffin, 1kg of diisooctyl terephthalate, 0.5kg of N-isopropyl-N'-phenyl-p-phenylenediamine, 3kg of dicumyl peroxide, 1kg of triene Acryl isocyanurate and 0.1 kg of sulfur.

Abstract

This application relates to a pin-through ball pin assembly and the polyurethane composite material used in the assembly. The pin-through ball pin assembly includes a polyurethane ball pin, which includes a sphere, a cylinder and a shaft hole. An annular rib; a spherical shell with a second annular groove on its end; an elastic sleeve; a sheath; and a sealing cover, which includes an annular base plate, an annular flange and a second annular rib, and the three are coaxially arranged; the spherical shell Connected to the outside of the sphere, the elastic sleeve is sleeved outside the spherical shell, and the sheath is sleeved outside the elastic sleeve; the sealing cover is arranged at both ends of the sheath, and the cylinder passes through the inner circle of the annular base plate and is sleeved by the annular flange. The inner ring surface of the annular flange is in close contact with the outer ring surface of the cylinder, and the second annular rib is clamped in the second annular groove. Polyurethane composite materials include polyurethane elastomer, vitrified microspheres, paraffin wax and polyethylene glycol fatty acid ester. The application can effectively reduce the leakage of lubricant from the ball and the shell of the ball.

Description

technical field [0001] The present application relates to the technical field of auto parts, in particular to a pin-through ball pin assembly and the polyurethane composite material used in the assembly. Background technique [0002] The ball pin assembly is an important part in the structure of the car. It has a very important impact on the normal driving and service life of the vehicle. [0003] At present, in the related art, in order to make the sphere of the ball pin rotate more smoothly in the sphere shell, a lubricant, such as molybdenum disulfide, is usually added between the sphere and the inner ring surface of the sphere shell. The rotation of the ball will drive the lubricant to cover the outer ring surface of the ball, and at the same time, the lubricant will leak from the gap between the ball and the shell, thereby contaminating the ball pin assembly or other structures of the car. Even if the sealing ring is added, lubricant will still leak from the gap betwe...
