Description
Technical field
The invention belongs to auto parts machinery field, particularly a kind of vehicle clutch disengaging bearing assembly.
Background technique
Clutch a kind of vitals that to be a kind of control engine power that existing manual-gear vehicle is conventional be switched on or switched off with transmission system, the separation of clutch with in conjunction be rely on stacked clutch plate to separate or in conjunction with and realization.Clutch separate or in conjunction with time in High Rotation Speed state, so separating between clutch plate with combination is to rely on external force to be applied on clutch release bearing, pass to again the control unit of clutch plate, so not only ensured the transmission of power but also ensured that clutch is in High Rotation Speed state, because clutch release bearing is under High Rotation Speed, between its bearing inner race bearing outer ring rolling element, there is gap simultaneously, between gland assembly and clutch drived disk assy, under fricative dust and rugged environment condition, airborne dust all can enter between bearing outer ring bearing inner race and rolling element, owing to containing in these dust, a large amount of hard material enters bearing inside later and the lubricating grease of bearing inside bonds together, between bearing inner race and rolling element, between bearing outer ring and rolling element, form wearing and tearing, then damaging bearing lost efficacy clutch, cause major accident hidden danger in Vehicle Driving Cycle process, people want to have use up a lot of ways for fear of the generation of this phenomenon, for example install dust cover additional in the end of bearing inner race and outer ring, between release bearing housing and bearing inner race, increase the methods such as dust-proof seal ring.Can reduce in a large number the infringement of dust to bearing, but owing to having space between the upper end of rolling bearing and outer casing, dust accumulates in gap, just can enter into by this space the upper end of rolling bearing, enter into rolling bearing inside by the inner ring of upper end dust cover and the gap of bearing inner race, can cause equally the Rapid Damage of bearing.
Summary of the invention
The above defect existing for existing clutch release bearing assembly, proposes a kind of clutch bearing separating assembly, comprises housing, rolling bearing, outer casing, and bottom dust-proof seal ring, is characterized in that: also comprise top dust-proof seal ring; Rolling bearing is arranged on the step place, one end of housing, and outer casing is arranged on housing and by rolling bearing letter and draws together in it; Bottom dust-proof seal ring is arranged between rolling bearing inner ring and housing; Described top dust-proof seal ring is arranged between outer casing and rolling bearing inner ring or is arranged between rolling bearing inner ring and housing washer, and dust-proof seal ring adopts monolateral fixing being fixed on bearing inner race step or on outer casing or bearing outer ring; Described top dust-proof seal ring is made up of rubber material, has skeleton, You Chun limit, its edge in the middle of it; Described skeleton is made up of metallic material; Described skeleton is arranged on needs fixing one side, and one side is corresponding thereto lip limit.
Beneficial effect
Beneficial effect of the present invention is, can effectively prevent that dust from entering into the accumulation of bearing dustproof cover part and entering rolling bearing inside from bearing upper end portion from outside, effectively extends bearing working life.
