Embodiment 1

[0046] refer to figure 1 with figure 2 , the embodiment of the present application discloses an intermediate support bearing assembly, which is used in cooperation with an automobile transmission shaft. The intermediate support bearing assembly includes a polyurethane ball head 1, a ball head shell 2, a bearing seat 3 and a support seat 4.

[0047] refer to figure 2 with image 3, The polyurethane ball head 1 has a shaft hole 11 and a shaft sleeve 12 . Wherein, the shaft-through hole 11 passes through the polyurethane ball head 1 in a radial direction, and has openings on opposite sides of the polyurethane ball head 1 . The shaft sleeve 12 is a cylindrical structure with a radial section of a ring, and there are two sets, which are respectively symmetrically arranged at the openings of the shaft passing hole 11 on opposite sides of the polyurethane ball head 1 and extend outward. During use, the power transmission shaft of the automobile is passed through the shaft hole...

Embodiment 2

[0082] An intermediate support bearing assembly disclosed in this embodiment and the polyurethane composite material used for the assembly are basically the same as in Example 1, the difference is that the composition ratio of the polyurethane composite material is different, specifically: polyurethane elastomer 100kg , microcapsule lauryl alcohol 5kg, plant fiber 12kg, polyethylene glycol fatty acid ester 0.5kg, paraffin 1kg, starch 8kg, polytetrafluoroethylene powder 5kg, stearic acid 1kg, molybdenum disulfide 4kg, carbon black 35kg, 0.5kg of plasticizer, 1.5kg of anti-aging agent, 3kg of vulcanizing agent, 1.3kg of vulcanization auxiliary agent and 0.1kg of sulfur.

Embodiment 3

[0084] An intermediate support bearing assembly disclosed in this embodiment and the polyurethane composite material used for the assembly are basically the same as in Example 1, the difference is that the composition ratio of the polyurethane composite material is different, specifically: polyurethane elastomer 100kg , microcapsule lauryl alcohol 8kg, plant fiber 3kg, polyethylene glycol fatty acid ester 2kg, paraffin 5kg, starch 15kg, polytetrafluoroethylene powder 2kg, stearic acid 5kg, molybdenum disulfide 1kg, carbon black 20kg, plasticizer 1.5kg of anti-aging agent, 0.5kg of anti-aging agent, 4kg of vulcanizing agent, 0.8kg of vulcanization auxiliary agent and 0.3kg of sulfur.

Abstract

The application relates to an intermediate support bearing assembly and a polyurethane composite material used for the assembly. The intermediate support bearing assembly includes a polyurethane ball head with a shaft hole; a ball head shell, which is an inner ring surface and a polyurethane ball head outer A cylindrical shell with matching ring surfaces, and first openings are provided at both ends; a bearing seat, which has a hollow cavity that can accommodate a ball head shell, and the hollow cavity is provided with second openings on opposite sides of the bearing seat; and a support seat; the ball head The shell is set outside the polyurethane ball head; at the same time, the ball head shell is set in the hollow cavity, and the two ends of the ball head shell are respectively connected with the hollow cavity wall through the first elastic member; The first opening and the second opening communicate with the outside world. The polyurethane composite material used in this assembly includes polyurethane elastomer, microencapsulated lauryl alcohol, polyethylene glycol fatty acid ester, paraffin and starch. The intermediate support bearing assembly of the present application can adjust and compensate the inclination angle change of the automobile transmission shaft.

Description

technical field [0001] The present application relates to the technical field of auto parts, in particular to an intermediate support bearing assembly and a polyurethane composite material used in the assembly. Background technique [0002] The drive shaft is the part that transmits power in the car and is connected between the gearbox and the rear axle. The intermediate support bearing assembly is installed at the chassis of the vehicle to support the rotation of the transmission shaft and prevent the radial movement of the transmission shaft. [0003] At present, when the whole vehicle is running, the movement of the engine or the deformation of the frame will cause the inclination angle of the transmission shaft of the vehicle to change during the working process, resulting in a decrease in the transmission efficiency of the transmission shaft and affecting its service life. In the related art, the intermediate support bearing assembly is usually fixedly connected to the...
