Abstract

The utility model belongs to the field of mechanical operation, and relates to a knuckle bearing of an automobile shock absorber. The knuckle bearing comprises an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, wherein the outer surface of the inner ring is matched with the inner surface of the outer ring in size, and the outer ring is sleeved outside the inner ring. The knuckle bearing is characterized in that multiple pits are arranged on the inner surface of the outer ring and the outer surface of the inner ring; and a lubricant is filled in the gap of the contact surface between the inner ring and the outer ring. In the utility model, dot-matrix open pits are arranged on the outer surface of the inner ring and the inner surface of the outer ring of the knuckle bearing respectively, and a sufficient lubrication effect is realized by filling a solid lubricant to form self-sealing lubrication and further prolong the service life of the automobile shock absorber.

Description

A kind of joint shaft bearing of automobile absorber

Technical field

The utility model belongs to the mechanical work field, is a kind of joint shaft bearing of automobile absorber.

Background technique

Under the conventional lubrication condition, in vehicle traveling process, the joint shaft bearing work of vibration damper, bearing inner race is inner rotation in the outer ring, and fricative oil film reached lubricated purpose after the rubbing surface when relying on non-the friction adhered to lubricant oil.Critical load problem when rubbing surface initially contacted when this lubricating system can only solve mechanical transmission position transmission of power; Variation along with mechanical movement environment terms and conditions; Conventional lubrication method and lubricant medium all can not make rubbing surface at utmost reduce wear; Lubricated effective date can not prolong at double, and the oiling agent storage that friction retains on the interface when taking place can't be guaranteed.

The model utility content

The purpose of the utility model provides a kind of joint shaft bearing of automobile absorber, improves joint shaft bearing and in use is easy to the present situation of wearing and tearing, and prolongs the working life of automobile absorber.

The technological scheme of the utility model is a kind of joint shaft bearing of automobile absorber; It comprises inner ring with outer spherical surface and the outer ring with inner ball surface; The outer surface of inner ring cooperates with the internal surface size of outer ring; The outer ring is sleeved on outside the inner ring, it is characterized in that: the internal surface of outer ring and the outer surface of inner ring have some pits, and the gap of inner ring and outer ring surface of contact is filled with oiling agent.

Described pit is the open pit of dot matrix, and the size of pit is Φ 2.5mm*1mm, and the distance between adjacent two pits is 5mm.

Described oiling agent adopts solid lubricant, and the standard of using of oiling agent is freely overflowed as inner ring and outer ring gap location.

The characteristics of the utility model are to adopt the open pit of dot matrix respectively at the inner ring outer surface of joint shaft bearing and inner surface; And reach the effect of sufficient lubrication through filling solid lubricant; It is lubricated to make it form selfsealings, has prolonged the working life of automobile absorber.

Description of drawings

To combine embodiment that the utility model is further described below.

Fig. 1 is the structural representation of the joint shaft bearing of vehicle shock absorber.

Fig. 2 is a joint shaft bearing outer ring structure schematic representation.

Fig. 3 is a joint shaft bearing inner ring structural representation.

Among the figure: 1, outer ring; 2, inner surface; 3, inner ring; 4, inner ring outer surface; 5, pit.

Embodiment

As shown in Figure 1, outer ring 1 is a hollow structure, has spherical internal surface 2.Inner ring 3 also is the spherical structure of hollow, has spherical outer surface 4.The physical dimension of inner surface 2 and inner ring outer surface 4 matches, and the outside that outer ring 1 is sleeved on inner ring 3 has constituted joint shaft bearing.

Shown in Fig. 2 and 3, the internal surface 2 of outer ring 1 and the outer surface 4 of inner ring 3 are furnished with the open pit 5 of some dot matrixs respectively, and the size of pit is Φ 2.5mm*1mm, and the distance between adjacent two pits is 5mm.

The gap of outer ring 1 and inner ring 3 surface of contact scribbles solid lubricant, and the standard of using of oiling agent is freely overflowed as inner ring and outer ring gap location.

In the automobile running, automobile absorber is started working, and joint shaft bearing is worked thereupon; Inner ring 3 is 1 inner rotation in the outer ring; Because surface of contact has pit and oiling agent, in the gap of inner ring 3 and outer ring 1, formed the film of oiling agent, the free of discontinuities of oiling agent is replenished when guaranteeing 1 friction in inner ring 3 and outer ring; Prolonged the working life of joint shaft bearing, and then strengthened the performance and the working life of automobile absorber.
