Description
Technical field
The utility model relates to the component on the drum brake that a kind of automobile brake uses, and specifically, particularly relates to a kind of braking shoes.
Background technique
In Motor Vehicle Braking Procedure, drum brake provides the vitals of braking force, and brake shoe is a vital part in the drum brake, and in general, brake shoe is formed through glue bonding or rivet by braking shoes and friction plate.
Though existing drum brake structure is very ripe, uses for many years, has the deficiency of following two aspects:
There is not the friction plate positioning device on one of which, the braking shoes.Can't accurately not locate when having positioning device can cause braking shoes and friction plate bonding on the shoes, cause the initial angle conformity of friction plate poor, thereby influence the conformity of brake efficiency.Even if each brake shoe manufacturer takes a lot of means to remove to control the initial angle of friction plate when bonding at present; For example at the corresponding mark line of position punching press of shoes wing plate friction plate initial angle;, friction plate and braking shoes lean on workman's naked eyes to judge mark line when boning then; Unavoidable like this erroneous judgement, the generation error of having; Aimed at mark line even if the workman bonds during friction plate,, before drying adhesive, also inconsistent phenomenon possibly take place under the seizing force effect of friction plate at bundling belt, caused the friction plate initial angle to depart from the binding bake process.Some producer utilizes some high-end technologies in addition; Such as on the anchor clamps of friction plate and the bonding binding of braking shoes, loading onto alignment sensor; To solve the purpose of friction plate location; But this solution makes frock clamping complicated, and manufacture cost and device maintenance cost increase greatly, and can't solve the problem that before drying adhesive, possibly misplace under the seizing force effect of friction plate at bundling belt equally.
Two, the drum brake brake shoe does not have the wear warning of friction plate function.There is not the wear warning of friction plate function may cause the user after in use the friction plate of brake shoe weares and teares fully; The shoes metal directly contacts the back with the brake drum metal and takes place just to perceive behind the brake noise; This moment, braking force can be lost more than 80%, had major safety risks.
The model utility content
To the problems referred to above, the utility model provides a kind of braking shoes, and this braking shoes not only can satisfy all functions of existing braking shoes; And can make the friction plate location; Solve the problem that friction plate possibly misplace, simultaneously, also have the function of wear warning of friction plate.
The utility model is realized through following technological means: a kind of braking shoes, comprise web and wing plate, and wing plate is connected with the arc-shaped circumference of web, and said wing plate is arch; Also comprise the locating alarming boss, said locating alarming boss is positioned on the surface of contact of wing plate and friction plate.
When friction plate bonds with the braking shoes; Aiming at corresponding locating alarming boss to friction plate one end gets final product; In the binding bake process; Friction plate only can be in the maximum allowance scope of locating alarming lug boss position minute movement, thereby solved the inaccurate and binding bake process friction plate of the friction plate initial position problem of misalignment of sliding easily.
The utility model also can be done following improvement:
Said locating alarming boss need not additional process by being stamped to form on the wing plate, does not increase manufacture cost.
Said locating alarming boss height is the 0.5-5 millimeter, and the height of this locating alarming boss is the thickness limit that the friction plate of designing requirement (4) allows wearing and tearing, therefore can design according to actual needs.
During use, when friction disc wear during to the thickness limit (being the height of locating alarming boss) of designing requirement, the locating alarming boss just can directly contact the shriek that sends the metal direct friction with brake drum, thereby reminds driver's friction plate to arrive wear limit.
The preferred 1-2 millimeter of said locating alarming boss height.
Said locating alarming boss is at least two, is distributed on the position of wing plate requirement, promptly is positioned at around the friction plate position of limiting friction sheet.
Preferred 4 of said locating alarming boss, 2 is one group, and wherein one group of initial angle α that is positioned at brake shoe goes up (promptly the angle to center line is α), and another group is positioned at the cornerite β terminal (promptly the angle to center line is an alpha+beta) of brake shoe.
Said locating alarming boss forms continuous strip projected parts around friction plate.Friction plate is limited in the space that this convexity surrounds fully.
Compared with prior art, the beneficial effect that the utlity model has is:
1) a kind of braking shoes of the utility model; Through the locating alarming boss is set, not only can satisfy the functional requirement of conventional brake shoes, and also more accurate than the general orientation type of present friction plate location; The product of being forbidden to scrap because of the location in the production process almost can arrive zero; The frock clamping that bundlees equipment simultaneously can be simplified greatly, and manufacture cost reduces greatly, and constant product quality property improves greatly.
2) a kind of braking shoes of the utility model; Also possessed the wear warning of friction plate function; Remind driver's renewal of facing renewal more on time, avoid friction disc wear to cause the caused traffic accident of misfunctioning of brake, protected driver's personal safety and property safety to the limit.
3) a kind of braking shoes of the utility model, the design of its locating alarming boss, principle is reliable, and technology is simple, does not increase extra manufacturing process, has very strong actual operation.
