The technical solution of the utility model: a kind of automobile absorber bearing, include bearing upper cover, bearing lower cover, described bearing upper cover, between bearing lower cover, be provided with rolling element, for the retainer of rolling element is installed, described bearing upper cover is provided with circle raceway groove, under bearing, cover and be provided with lower circle raceway groove, described rolling element is positioned at circle raceway groove, in lower circle raceway groove, it is characterized in that: the inner side of described bearing lower cover, outside is respectively equipped with interior sealing lip, outer seal lip, described bearing upper cover is provided with respectively and interior sealing lip, the inner sealing surface that outer seal lip matches, external sealed face, described interior sealing lip, outer seal lip respectively with inner sealing surface, external sealed face is conflicted and is formed the sealing of bearing upper cover and bearing lower cover.
Adopt technique scheme, interior sealing lip by covering under bearing, outer seal lip respectively with bearing upper cover on inner sealing surface, external sealed face conflict to form the sealing of bearing upper cover and bearing lower cover, make like this automobile absorber bearing of this structure, good airproof performance, can prevent well that outside muddy water and dust from entering bearing inside, affect its service behaviour, thereby make its long service life.
Further setting of the present utility model: the lip sheet that described interior sealing lip, outer seal lip includes joint, is wholely set with joint, described interior sealing lip, the joint of outer seal lip are connected with bearing lower cover, and described interior sealing lip, the lip sheet of outer seal lip and inner sealing surface, external sealed face are conflicted.
Adopt above-mentioned further setting, the interior sealing lip of this structure, outer seal lip set-up mode, easy to process, lip sheet is sheet, like this and between joint, there is certain elastic force, thus make good airproof performance between the lip sheet of interior sealing lip, outer seal lip and inner sealing surface, external sealed face.
Of the present utility modelly further arrange again: under described bearing, cover corresponding in the joint, the joint position of outer seal lip of sealing lip be respectively equipped with inner groovy, outer groove, the joint of described interior sealing lip, the joint of outer seal lip are embedded respectively in described inner groovy, outer groove.
Adopt above-mentioned further setting again, interior sealing lip, outer seal lip and the bearing lower cover Placement of this structure, simple in structure, stable connection.
Further setting of the present utility model: described interior sealing lip, the lip sheet of outer seal lip and inner sealing surface, the interference of external sealed face are conflicted.
Adopt above-mentioned further setting, can make the sealability between bearing upper cover and bearing lower cover better, thereby can further prevent that outside muddy water and dust from entering bearing inside, affect its service behaviour.
Further setting more of the present utility model: the lip position of described interior sealing lip, the lip sheet of outer seal lip is coated with lube layer.
Adopt above-mentioned further setting again, setting is lube layer, can reduce the wearing and tearing between the lip sheet of interior sealing lip, outer seal lip and inner sealing surface, external sealed face, thereby make to have reduced bearing frictional torque, and then vehicle steering wheel is turned round more flexibly.
