Description

A kind of brake slack adjuster using engagement sleeve antioverloading function

Technical field

It is the utility model is related to a kind of brake slack adjuster for automobile brake, more particularly to a kind of to use gear The brake slack adjuster of clutch antioverloading function is mainly used for brake clearance automatic adjustment, it is ensured that brake clearance is constant, system Dynamic continuous and effective.

Background technology

The operation principle of existing vehicle brake gap automatic regulator is：When brake clearance is excessive, pressure arm pushes, Set rotation is alloted in drive, is alloted and is sleeved on the lower drive self-regulated shaft rotation of unilateral bearing effect, outer shifting block is in ball-and-socket, steel ball and spring Under the action of follow self-regulated shaft to rotate, outer shifting block links screw putter, drives screw putter rotation, generate displacement realize from Dynamic adjustment brake clearance is insufficient, reaches braking effect, when brake clearance meets the requirements, when pressure arm pushes, screw putter without Method generates displacement, to the steel ball between self-regulated shaft and outer shifting block, by overcoming the application pressure of spring, in ball-and-socket also ball-and-socket Between roll, come eliminate pressure arm push generate twisting resistance work as braking to protect adjuster inner components not to be damaged When gap is too small, this just needs to adjust outer shifting block by adjusting mandrel, to drive screw putter to rotate, reaches the braking of requirement Gap.The adjuster of this structure, using unilateral bearing, socket arrangement is rolled between ball-and-socket to realize that overload is protected by steel ball Shield, fixed plate component are molded using injection molding manner.But the defect of such framework is：1, unilateral bearing and allot set between matching Size is closed, control machining tolerance easy tos produce useless part, increases production finished product, dimensional fits are bad, unilateral bearing can be caused to deform Or fall off, increase adjuster hidden danger；2, the undesirable influence steel ball rolling of ball-and-socket, it may appear that steel ball clamping stagnation or abnormal sound；3, solid Fixed board injection molding, the force value or braking number for bearing certain effect can excessively cause molded portion to deform, influence assembly overload The control of protection force value causes adjuster to adjust disabler.

Utility model content

Pass through the retrieval to existing patent document, it has been found that there are no brake slack adjusters to promote braking ability and system Dynamic service life, the relevant report of guarantee driving safety.

Existing poor stop and braking short life are solved the problems, such as this, and the purpose of this utility model is to provide one kind Using the brake slack adjuster of engagement sleeve antioverloading function, existing safety is hidden between eliminating each parts of adjuster Suffer from, promote product service life, thoroughly avoids the synthtic price index such as the short life, the disabler that occur during product use.It protects It is complete to hinder brake overall structure, promotes braking ability and braking service life, guarantee driving safety, to solve in above-mentioned background technology The problem of proposition.
