Abstract
The invention provides a kind of brake shoe iron, belong to automobile brake component technical field.Comprise web and wing plate, wing plate is connected with the arc-shaped circumference of web, and described wing plate is arch; Also comprise locating alarming boss, described locating alarming boss is positioned on the surface of contact of wing plate and friction plate.By arranging locating alarming boss, make the location of friction plate more accurate, also possessed wear warning of friction plate function simultaneously, not only can reduce in production process because friction plate locates the reject rate being forbidden to cause, also simplify the frock clamping of binding equipment, reduce manufacture cost, improve product quality stability.This technology can be widely used in automobile drum brake.
Description
Technical field
The present invention relates to the component on a kind of drum brake of automobile brake, specifically, particularly relate to a kind of brake shoe iron.
Background technique
In Motor Vehicle Braking Procedure, drum brake is to provide the vitals of braking force, and brake shoe is a vital part in drum brake, and in general, brake shoe to be bondd by glue by brake shoe iron and friction plate or rivet forms.
Although existing drum brake structure is very ripe, for many years, there is the deficiency of following two aspects in application:
One, brake shoe iron there is no friction plate positioning device.Accurately cannot locate when shoes not having positioning device brake shoe iron and friction plate can be caused to bond, cause the initial angle conformity of friction plate poor, thus affect the conformity of brake efficiency.Initial angle when even if current each brake shoe manufacturer takes a lot of means to go control friction plate bonding, such as at position punching press mark line that shoes wing plate friction plate initial angle is corresponding, then mark line is judged when friction plate and brake shoe iron bond by workman's naked eyes, have erroneous judgement unavoidably like this, produce error; Targeted by mark line even if workman bonds during friction plate, at binding bake process, under the seizing force effect at bundling belt of the front friction plate of drying adhesive, also inconsistent phenomenon may occur, cause friction plate initial angle to depart from.Some producer utilizes some high-end technologies in addition, such as on the fixture of friction plate binding bonding with brake shoe iron, load onto alignment sensor, to solve the object of friction plate location, but this solution makes frock clamping complicated, manufacture cost and device maintenance cost increase greatly, and the problem that misplaces may occur under the seizing force effect of the front friction plate that cannot solve equally at drying adhesive at bundling belt.
Two, drum brake brake shoe does not have wear warning of friction plate function.After not having wear warning of friction plate function that the friction plate of user's in use brake shoe may be caused to wear and tear completely, shoes metal and brake drum metal are just perceiveed after directly contacting rear generation brake noise, now braking force can lose more than 80%, there are major safety risks.
Summary of the invention
For the problems referred to above, the invention provides a kind of brake shoe iron, this brake shoe iron not only can meet all functions of existing brake shoe iron, and friction plate can be made to locate, solve the problem that friction plate may occur to misplace, meanwhile, also there is the function of wear warning of friction plate.
The present invention is realized by following technological means: a kind of brake shoe iron, comprises web and wing plate, and wing plate is connected with the arc-shaped circumference of web, and described wing plate is arch; Also comprise locating alarming boss, described locating alarming boss is positioned on the surface of contact of wing plate and friction plate.
When friction plate and brake shoe iron bond, corresponding locating alarming boss is aimed in friction plate one end, in binding bake process, friction plate only can within the scope of the maximum allowance of locating alarming lug boss position minute movement, thus solve the inaccurate and binding bake process friction plate of friction plate initial position and easily to slide problem of misalignment.
The present invention also can do following improvement:
Described locating alarming boss is stamped to form by wing plate, without the need to additional process, does not increase manufacture cost.
Described locating alarming boss height is 0.5-5 millimeter, and the height of this locating alarming boss and the friction plate (4) of designing requirement allow the thickness limit of wearing and tearing, therefore can design according to actual needs.
During use, when friction disc wear is to thickness limit (i.e. the height of locating alarming boss) of designing requirement, locating alarming boss just can directly contact with brake drum the shriek sending metal direct friction, thus reminds driver's friction plate to arrive wear limit.
The preferred 1-2 millimeter of described locating alarming boss height.
Described locating alarming boss is at least two, is distributed on the position of wing plate requirement, is namely positioned at around friction plate, the position of limiting friction sheet.
Described locating alarming boss preferably 4,2 is one group, and wherein one group is positioned at (angle namely arriving center line is α) on the initial angle α of brake shoe, and another group is positioned at the cornerite β end (angle namely arriving center line is alpha+beta) of brake shoe.
Described locating alarming boss forms continuous print strip projected parts around friction plate.Friction plate is limited to completely in space that this projection surrounds.
Compared with prior art, the beneficial effect that the present invention has is:
1) a kind of brake shoe iron of the present invention, by arranging locating alarming boss, not only can meet the functional requirement of conventional brake shoes, and it is more accurate than current friction plate general orientation type location, because location is forbidden the product scrapped almost can arrive zero in production process, the frock clamping simultaneously bundling equipment can simplify greatly, and manufacture cost reduces greatly, and constant product quality improves greatly.
2) a kind of brake shoe iron of the present invention, has also possessed wear warning of friction plate function, reminds driver's more renewal of facing renewal on time, avoids friction disc wear to cause the traffic accident caused by misfunctioning of brake to the limit, protect personal safety and the property safety of driver.
3) a kind of brake shoe iron of the present invention, the design of its locating alarming boss, principle is reliable, and technique is simple, does not increase extra manufacturing process, has very strong actual operation.
