Abstract
The utility model relates to a brake assembly, in particular to a lubricating brake adjusting arm, which comprises an adjusting arm shell and a worm shaft assembly, wherein the worm shaft assembly is arranged in the shell, and comprises a worm shaft, a worm and a locking sleeve, the worm and the locking sleeve are sleeved on the worm shaft in sequence, a steel bowl is arranged in the locking sleeve, a lubricating oil inlet hole is formed in the locking sleeve, and the lubricating oil inlet hole is arranged corresponding to the steel bowl. According to the above structure, the lubricating oil inlet hole is added in the locking sleeve, and the effect of lubricating the steel bowl is achieved in the manner that grease is added from a nozzle to reach the lubricating oil inlet hole, so that steel balls in the steel bowl are prevented from deforming, and the service life of the lubricating brake adjusting arm is prolonged.
Description
Technical field
The utility model relates to a kind of brake assemblies, especially a kind of lubricated braking adjusting-arm.
Background technique
The function of braking adjusting-arm should be the gap increasing amount that accurately record causes due to the friction facing wearing and tearing, and accurately braking gap is adjusted to normal operating range.Angle stroke during braking, the angle stroke of adjusting arm during braking can be divided into three parts:
1, gap angle, corresponding to the normal clearance of brake drum and friction facing;
2, excess gap angle, corresponding to the gap increased because of the friction facing wearing and tearing;
3, elastic angle, the elasticity caused corresponding to by brake drum, friction facing and brake cylinder and braking system power transmission the time.
When adjusting automatically, gap should avoid the elastic angle in the stroke of angle as far as possible.If do not distinguish excess gap angle and elastic angle, compensated at any time without exception, will cause adjustment excessive, so that cause " dawdling " even " locking ".When the automatic adjusting arm working procedure starts to brake, adjust arm drive camshaft and turn over gap angle and excess gap angle, and the wearing and tearing that accurately record produces.Now the cam angle stroke is in interstitial area, and the characteristics of interstitial area are that braking moment changes not quite.While continuing brake, the cam angle stroke enters the elastic deformation area, and braking moment sharply rises, until car stops.Unclamp pedal, the brake backhaul, braking moment descends, and the cam angle stroke is got back to interstitial area.Automatic adjusting arm is according to the excess gap of when brake record, and internal adjustment mechanism drives camshaft by worm gear and turns over several angle, thereby completes once adjustment.
But prior art, lubricant oil advances less than the lock sleeve the inside, easily causes the lock sleeve inner spring life-span to shorten, and causes brake failure.
Summary of the invention
The purpose of this utility model is, a kind of lubricated braking adjusting-arm that extends the braking adjusting-arm life-span is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of lubricated braking adjusting-arm, comprise and adjust arm housing, worm shaft assembly, the worm shaft assembly is arranged in housing, the worm shaft assembly comprises worm shaft, worm screw, lock sleeve, worm screw, lock sleeve are set on worm shaft successively, be provided with the steel bowl in lock sleeve, be provided with lubricated oil inlet hole on lock sleeve, lubricated oil inlet hole setting corresponding to the steel bowl.
Of the present utility modelly further be set to: be provided with oil nozzle adjusting the arm housing bottom, oil nozzle is provided with guard shield.
Of the present utility modelly further be set to: also comprise screw gate, return spring, worm shaft is provided with the spring chamber of an opening, return spring is placed in spring chamber, screw gate is fixed on the opening of spring chamber, one end withstands return spring, offer two holes on the sidewall of spring chamber, place small ball in hole.
Of the present utility modelly further be set to: be provided with a big steel ball between return spring and screw gate, big steel ball one end withstands return spring, and the other end withstands screw gate one end.
Of the present utility modelly further be set to: be provided with a worm screw chamber adjusting on arm housing, the worm shaft assembly coordinates with the grafting of worm screw chamber.
Said structure has increased lubricated oil inlet hole in lock sleeve, by oil nozzle, adds butter to arrive lubricated essential oil hole, plays the effect of lubricated steel bowl, and the steel ball in the steel bowl just obtains ensureing and can't be out of shape so, increases the service life.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is the present embodiment;
