Abstract

The invention discloses a clutch bearing separation assembly, and belongs to the field of automobile accessories. The assembly comprises a shell, a rolling bearing, a protection cover and a lower dustproof sealing ring and further comprises an upper dustproof sealing ring; the rolling bearing is mounted at the step of one end of the shell, and the protection cover is mounted on the shell and covers the rolling bearing; the lower dustproof sealing ring is mounted between a bearing inner ring and the shell; the upper dustproof sealing ring is mounted between the protection cover and the bearing inner ring; and the dustproof sealing ring is fixed through a single side and fixed to the step of the bearing inner ring and protection cover. The assembly can effectively prevent dust from entering a bearing dustproof cover part from the outside to be accumulated, the dust enters the interior of the rolling bearing from the upper portion of the bearing, and therefore the service life of the bearing is effectively prolonged.

Description

A kind of clutch release bearing assembly

Technical field

The invention belongs to auto parts machinery field, particularly a kind of vehicle clutch disengaging bearing assembly.

Background technique

A kind of a kind of vitals controlling engine power and transmission system and be switched on or switched off that clutch is that existing manual-gear vehicle is commonly used, the separation of clutch relies on stacked clutch plate to be separated or to combine with combination and realizes.Clutch be separated or in conjunction with time be in High Rotation Speed state, so being separated with combination between clutch plate is rely on external force to be applied on clutch release bearing, pass to the control unit of clutch plate again, so both ensure that the transmission of power in turn ensure that clutch is in High Rotation Speed state, under clutch release bearing is in High Rotation Speed, there is gap between its bearing inner race bearing outer ring rolling element simultaneously, dust between gland assembly and clutch drived disk assy under fricative dust and rugged environment condition in air all can enter between bearing outer ring bearing inner race and rolling element, bond together owing to entering Bearing inner lubricating grease that is later and Bearing inner containing a large amount of hard material in these dust, between bearing inner race and rolling element, wearing and tearing are formed between bearing outer ring and rolling element, then damaging bearing makes clutch lose efficacy, cause major accident hidden danger in vehicle travel process, people want to have use up a lot of way in order to avoid the generation of this phenomenon, such as install dust cover additional in the end of bearing inner race and outer ring, the methods such as dust-proof seal ring are increased between release bearing housing and bearing inner race.The infringement of dust to bearing can be reduced in a large number, but owing to having space between the upper end of rolling bearing and outer casing, dust accumulates in gap, the upper end of rolling bearing just can be entered into by this space, enter into rolling bearing inside by the inner ring of upper end dust cover and the gap of bearing inner race, the Rapid Damage of bearing can be caused equally.

Summary of the invention

For the above defect that existing clutch release bearing assembly exists, propose a kind of clutch bearing separating assembly, comprise housing, rolling bearing, outer casing, 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 to be arranged on housing and to draw together in it by rolling bearing letter; 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 and monolaterally fixing is namely 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, corresponding thereto be lip limit.

Beneficial effect

Beneficial effect of the present invention is, can effectively prevent dust from entering into bearing dustproof cover partial buildup from outside and entering rolling bearing inside from bearing upper end portion, effectively extends bearing working life.
