Description
Technical field
The utility model relates to technical field of bearings, and especially a kind of vehicle clutch disengaging bearing unit specifically is the pull type clutch release bearing unit with self-aligning function.
Background technique
At present, clutch release bearing is important part on the automobile, breaks down if maintaining is bad, not only can cause economic loss, and dismounting once quite the trouble, need expend a lot of man-hours.So, understand fully the reason that clutch release bearing breaks down, and care and maintenance reasonably in use, to prolonging the life-span of release bearing, raise labour productivity, it is all significant to obtain favorable economic benefit.
Clutch release bearing is installed between the clutch internal speed changer, declutch shaft bearing pine is enclosed within on the atubular extension part of transmission drive gear bearing lid, make the convex shoulder of release bearing prop up withdrawal fork all the time by return spring, and retreat to the rearmost position, with the gap about separator levers maintenance 2.5mm.Because clutch pressure plate, separator levers and engine crankshaft run-in synchronism, and withdrawal fork can only move axially along clutch output shaft, it obviously is not all right directly going to dial separator levers with withdrawal fork, can make separator levers rotate an edge clutch output shaft on one side by release bearing moves axially, thereby it is smooth-going to have guaranteed that clutch can engage, separate softly, reduce wear, prolong the working life of clutch and whole drive unit.
Clutch release bearing should move should be flexible, no sharp-pointed sound or catching phenomenon, and its axial clearance must not surpass 0.60mm, and inner race must not wear and tear above 0.30mm.
If clutch release bearing does not reach above requirement, just be considered as breaking down.
The effect of the radial centrifugal force when release bearing in use is subjected to thrust load, impulsive load and high speed rotating, in addition, because the counter-force of shift fork thrust and separator levers also forms torsional moment not on same straight line.Clutch release bearing works under hard conditions, high speed rotating and bear high-speed friction by phased manner, and temperature is higher, and lubricating condition is relatively poor, no cool condition.
The source of damage of clutch release bearing roughly has following several: 1) the too high generation of operating temperature is overheated, some vehicle free travel is adjusted excessive, make clutch separation not thorough, be in half and engage half point from state, this state causes dry friction and produces a large amount of heat and pass to release bearing, and bearing is heated and reaches certain temperature, butter fusing or dilution trickling, the release bearing temperature is further improved, when temperature acquires a certain degree, just burn out; 2) lack lubricant oil and wear and tear, cause the clutch release bearing oil starvation.Several times to tens times of wear extent after the wear extent of release bearing under unlubricated or few lubrication circumstances is lubricated often.Wearing and tearing increase, and temperature also will improve a lot, and are so just more fragile.Free travel too little or do not have free travel at all between general clutch release bearing and the separator levers, will make separator levers and release bearing be in normal jointing state.Release bearing is easy to generate fatigue ruption more.And the operating time is long more, and the temperature of bearing is also high more, easy more scaling loss, the working life of having reduced release bearing.In addition, whether separator levers is adjusted smoothly, and whether the release bearing return spring is good, and the damage of release bearing is also had a significant impact.
Above-mentioned damage often takes place in existing self-aligning pull type clutch release bearing unit easily, and therefore needing a kind of novel vehicle clutch disengaging bearing unit badly overcomes above-mentioned defective.
