Description

A kind of clutch release bearing assembly

Technical field

Belong to auto parts machinery field, particularly the self-aligning separable bearing of clutch assembly of manual gear vehicle application.

Background technique

On current manual-gear vehicle, the power that also extensively adopts clutch to carry out between motor and gearbox disconnects and is communicated with, its working principle is driver's let slip the clutch, actuator drives clutch shifter, apply external force by clutch release bearing to clutch compressing disc, thereby the friction plate that makes clutch is separated from each other or combination, because clutch is rotation status in the time of work, and clutch shifter is rotation status not, so, clutch release bearing total performance is by non-rotary pressure, be applied to a transition apparatus on the clutch compressing disc of rotation, if damaged, the inefficacy of clutch will be caused, cause danger to Vehicle Driving Cycle, current clutch release bearing assembly is mostly by housing, bearing inner race, rolling element, bearing outer ring, be arranged on the sealed at both ends lid of bearing, the compositions such as case, and the lubricated of bearing is to rely on to add lubricating grease from oil filler, lubricating grease immerses in the rolling element and bearing of bearing, between outer ring, lubricating of shape matched bearings, the defect of its existence is, to adopt pressure to inject owing to injecting the method for grease, and the oil quantity injecting can not be controlled, grease can not form circulation, under the High Rotation Speed of bearing, the lubricating grease even sex change of can at high temperature expanding, or grease mixes with dust, form caking, occupy bearing clearance, bearing rotary is obstructed even can not be rotated, and then cause the damage of bearing, clutch release bearing was lost efficacy.

Summary of the invention

For the defect of prior art, the present invention proposes a kind of clutch release bearing assembly, comprises housing, bearing inner race, rolling element, bearing outer ring, bearing seal cover, case, dust guard, is characterized in that: on housing, be provided with grease lubrication system, described grease lubrication system comprises filler opening, oil storage tank, oil spilling mouth; Described oil storage tank is arranged on the face of the disc and shaft neck one side of housing, joins with the lower end surface of bearing, and filler opening is arranged on bottom or the side of oil storage tank, and oil spilling mouth is arranged on bottom or side or the identical surface of the disc and shaft neck direction of oil storage tank; Certain distance is arranged at the bottom of oil spilling mouth and the bottom of oil storage tank, to guarantee having the grease of suitable quantity to exist in oil storage tank.Described oil spilling mouth is arranged on bottom or side or the identical surface of the disc and shaft neck direction of oil storage tank; The described bottom of oil spilling mouth and the distance of the bottom of oil storage tank, be more than or equal to zero, is less than or equal to the height of oil storage tank; The inner ring diameter of oil storage tank large with or equal the external diameter of axle journal, be less than the internal diameter of bearing outer ring, the race diameter of oil storage tank, is greater than the external diameter of bearing inner race, is less than or equal to the external diameter of bearing outer ring; The sectional dimension of described filler opening is less than the width dimensions of oil storage tank, is greater than 3 millimeters, and this is of a size of cross section is circular diameter or polygonal circumscribed circle diameter; The size of described oil spilling mouth is greater than 1 millimeter, is less than or equal to the width dimensions of oil storage tank, and this is of a size of cross section is circular diameter or polygonal circumscribed circle diameter.

Beneficial effect

Beneficial effect of the present invention is: the lubricated formation system that can make clutch release bearing, avoid causing due to the accumulation of grease the damage of bearing, simultaneously because grease is to inject under pressure, due to the new grease injecting and the effect of oil spilling mouth, the grease previously having injected can be discharged, thereby guarantee that the grease of lubricating bearings is fresh clean, guarantee bearing sufficient lubrication, extend bearing working life.
