Problems solved by technology

These two factors lead to poor shock absorption effect of plane bearings
[0006] Second, the axial dimension is large
[0009] However, the above-mentioned sliding bearing is similar to the plane bearing, consisting of three parts, the upper and lower races and the sliding body, and the number of parts is large, resulting in complicated assembly and high cost

Embodiment 1

[0034] This embodiment provides a kind of sliding bearing for automobile suspension, refer to image 3 and combine Figure 4-5 As shown, it includes a first seat ring 100 and a second seat ring 200 arranged coaxially, the first seat ring 100 is used for connecting the vehicle frame (not shown), and has a first surface 101 facing the second seat ring 200, The second seat ring 200 is used to connect the shock absorber (not shown), and has a second surface 201 facing the first seat ring 100, the first seat ring 100 and the second seat ring 200 have a certain distance in the axial direction, There is a gap between the first surface 101 and the second surface 201 . Both the first seat ring 100 and the second seat ring 200 are composite structures composed of steel bars embedded in polymer materials. The steel bars are used to strengthen the support rigidity of the sliding bearing. The polymer material can be self-lubricating polymer .

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that, referring to Figure 7 A plurality of grooves 211 are provided on the concave surface of the second raceway 210 , the plurality of grooves 211 are distributed at intervals along the circumference of the second raceway 210 , and the grooves 211 run through the second raceway 210 along the radial direction. The groove 211 has two functions, one is to accommodate lubricating oil, improve the degree of lubrication between the two raceways, and reduce dry friction; the other is to accommodate debris generated by friction between the two raceways, preventing the two The raceway surface is worn by debris.

[0050] In other embodiments, such as Figure 8 As shown, a groove 211 may also be provided on the convex first raceway, and the arrangement method is the same as that of this embodiment. It should be noted that the groove 211 can only be set on one of the first raceway 110 and the second raceway 210, but can...

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 is that, referring to Figure 9 , in the sliding bearing of this embodiment, the annular contact portion between the first raceway 110 and the second raceway 210 is a surface contact, and the contact surface between the first raceway 110 and the second raceway 210 is a plane.

[0053] Wherein the size of the contact surface in the radial direction is not greater than one-twentieth of the diameter of the convex surface of the first raceway 110 .

[0054] In this embodiment, the convex surface of the first raceway 110 and the concave surface of the second raceway 210 are formed by combining two sections of arc surfaces and a section of plane perpendicular to the axial direction of the bearing, wherein the plane is located between the two sections of arc surfaces, and the first The raceway 110 and the second raceway 210 are in contact through respective planes.

[0055] In other embodiments, the contact surface of th...

Abstract

The invention relates to a vehicle suspension sliding bearing, which comprises: a first housing washer and a second housing washer, wherein the first housing washer and the second housing washer are coaxially arranged, the first housing washer is provided with a first surface facing the second housing washer, the second housing washer is provided with a second surface facing the first housing washer, and a gap is arranged between the first surface and the second surface; and an annular first race arranged on the first surface and an annular second race arranged on the second surface, wherein one of the first race and the second race is a convex race, the other race is a concave race, the convex race and the concave race are coaxial with the bearing, the concave race is positioned inside the concave race and partially contact the concave race, the convex race and the concave race form at least an annular contact position, the annular contact position is linear contact or surface contact and is coaxial with the bearing, and the convex race and the concave race are respectively and fixedly arranged on the first housing washer and the second housing washer to replace the sliding sheet in the existing sliding bearing, such that the members of the whole sliding bearing are reduced so as to simplify the assembly and reduce the cost.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a sliding bearing used for automobile suspensions, especially MacPherson suspensions. Background technique [0002] McPherson suspension is currently the most widely used independent suspension in the front axle suspension of automobiles. Its biggest feature is the combination of shock absorbers and springs as a shock absorber. [0003] Such as figure 1 As shown, the MacPherson suspension generally includes a shock absorber 10 and a plane bearing 20 (also called a thrust ball bearing) connected to the top of the shock absorber 10, wherein the shock absorber 10 includes a shock absorber 11 and is sleeved on the shock absorber. The spring 12 outside the device 11, the plane bearing 20 includes an upper race 21, a lower race 22 and a rolling element 23 arranged between the upper and lower races, wherein the upper race 21 is connected with the vehicle body (not shown), and the lower The sea...
