Description

A kind of wedged type truck clutch release bearing

Technical field

It the utility model is related to clutch release bearing technical field, more particularly to a kind of wedged type truck clutch separation Bearing.

Background technology

Clutch release bearing is an important part on automobile, if the bad failure of maintaining, no But economic loss can be caused, and dismounting is once fairly cumbersome, need to expend many man-hours.So understand fully clutch release bearing The reason for breaking down, and reasonably care and maintenance, the service life to extending release bearing, raising work produce in use Rate, it is all significant to obtain preferable economic benefit.In use by axial load, shock loading and rotation at a high speed When radial centrifugal force effect, further, since shift fork thrust and the counter-force of separation lever are not on the same line, are also formed and turned round Torque.Clutch release bearing works under hard conditions, and high-speed rotation and bears high-speed friction by phased manner, and temperature is higher, lubrication Condition is poor, no cooling condition.

The damage of clutch release bearing and the operation of driver and maintenance, adjustment have much relations, and the source of damage is substantially Have following several：

1) operating temperature is excessive produces overheat

Many drivers usually partly step on clutch, some extension shelves rear feet are also placed on clutch pedal in turning or deceleration On；The adjustment of some vehicle free travels is excessive so that clutch separation is not thorough, in partly engaging semi-detached state, this shape State causes dry friction and produces substantial amounts of heat transfer to release bearing, and bearing is heated the temperature for reaching certain, butter fusing or dilute Trickling is released, further improves release bearing temperature, is just burnt out when temperature reaches a certain level.

2) lack lubricating oil and wear

Clutch release bearing is lubricated with butter, and the method that butter adds has two kinds, for 360111 release bearings, The rear cover of bearing should be opened and insert lubricating grease, rear cover is then filled into conjunction again again when safeguarding or when pulling down speed changer； For 788611K release bearings, then digestion in the lubricating grease for be placed on fusing can be pulled down, takes out, can reach after cooling The purpose of lubrication.Driver easily ignores this point in real work, causes clutch release bearing oil starvation.Unlubricated or few The wear extent of release bearing is often several times to tens times of wear extent after lubricating under lubrication circumstances.Abrasion increase, temperature It will improve a lot, it is thus more fragile.

3) free travel is too small or number of load is excessive

As requested, general clutch release bearing is more suitable for 2.5mm with separating the gap between lever, is reflected in Free travel on clutch pedal is 30-40mm, and free travel is too small or does not have free travel at all, it will makes separation lever Normal engagement state is in release bearing.According to fatigue rupture principle, the bearing working time is longer, and damaged condition is more serious；By It is more to carry number, the easier generation fatigue rupture of release bearing.And the working time is longer, the temperature of bearing is also higher, more holds Easy scaling loss, reduces the service life of release bearing.

4) in addition to three of the above reason, whether separation lever is adjusted so as to smooth, and whether release bearing return spring is good, right The damage of release bearing also has a significant impact.

Since the loading capacity of truck is big, inertia bigger, therefore in use to clutch separation in the process of moving The requirement higher of bearing.And assembling is inconvenient to be the problem of truck clutch release bearing is commonplace in assembling process.
