Summary of the invention
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provide a kind of simple in structure, with low cost, retro-speed is fast, retardation efficiency is high and economical with materials reduces the light stamping weldering shoes drum brake of brake noise.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of light stamping weldering shoes drum brake, comprise the air chamber support with air chamber, braking bottom board, two punching weldering shoes, described two punching weldering shoes one end is rotatably connected with braking bottom board by back shaft, air chamber support is fixedly connected with braking bottom board, also comprise the not uniform thickness friction plate fixing with the punching weldering shoes outside, be located at rotatable on the braking bottom board act on the camshaft of two punching weldering shoes the other end and be connected to two punching weldering shoes ends be used for strutting rush the return spring that the weldering shoes resets, described camshaft links to each other with air chamber by adjusting arm.
Above-mentioned light stamping weldering shoes drum brake, described not uniform thickness friction plate is fixing with the punching weldering shoes outside by rivet.
Above-mentioned light stamping weldering shoes drum brake, described air chamber is connected with the adjustment arm by the air-inlet cavity of being located in the air chamber support, and described adjustment arm links to each other with camshaft.
Above-mentioned light stamping weldering shoes drum brake, described neither uniform thickness friction plate all is set to its thickness from the middle structure that reduces gradually to two end part.
Above-mentioned light stamping weldering shoes drum brake, described camshaft is set to S shape structure, and two evagination circular arc part of described S shape structure contact with the end of two punching weldering shoes respectively.
The advantage of the utility model light stamping weldering shoes drum brake is: comprise braking bottom board, punching weldering shoes, not uniform thickness friction plate, back shaft, air chamber support, camshaft, return spring etc., punching weldering shoes is rigidly connected with rivet with uniform thickness friction plate not, shoes is connected by back shaft with base plate, shoes relies on the return spring return, camshaft with the torsion of air chamber turn to shoes thrust, thereby produce braking force.This break retardation efficiency is high, and is lightweight, and the friction plate utilization ratio is high, long service life.This break is applicable to the Light-duty Vehicle of all kinds of employing gas brakings.Adopt punching weldering shoes, intensity is cast shoes and is promoted 30%, and weight saving is more than 20%, and have the not available good plasticity of casting shoes, but the area of contact of Effective Raise friction plate and brake drum, thus braking force improved, reduce brake noise, improve the problems such as vehicle is stopped partially, shake; Adopt not uniform thickness friction plate, compare with existing uniform thickness friction plate, stock utilization improves 40%, improves nearly one times working life; Adopt large S-cam axle, retardation efficiency improves 10%.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure sectional view that the utility model is connected with air chamber support.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
Such as Fig. 1, shown in 2, a kind of light stamping weldering shoes drum brake, comprise the air chamber support 1 with air chamber 11, braking bottom board 2, shoes 3 is welded in rushing of the left and right sides, one end 31 of two punching weldering shoes 3 is rotatably connected with braking bottom board 2 by back shaft 4, air chamber support 1 is fixedly connected with braking bottom board 2, also comprise the not uniform thickness friction plate 5 fixing with the outside of punching weldering shoes 3, be located at rotatable on the braking bottom board 2 act on the camshaft 6 of two punching weldering shoes, 3 the other end 32 and be connected to two punching weldering shoes, 3 ends 32 be used for two strut rush the return spring 7 that weldering shoes 3 resets, camshaft 6 links to each other with air chamber 11, air chamber 11 is connected with adjustment arm 13 by the air-inlet cavity 12 of being located in the air chamber support 1, adjusts arm 13 and links to each other with camshaft 6.Camshaft 6 will from the torsion of air chamber 11, be converted into the thrust to two punching weldering shoes 3, thereby produce braking force.Camshaft 6 is set to S shape structure, and two evagination circular arc part of S shape structure contact with the end 32 of two punching weldering shoes 3 respectively.Arranged outside dust blocking tray 8 at braking bottom board 2.Wherein, uniform thickness friction plate 5 is not fixed by rivet 9 and the outside of punching weldering shoes 3.Neither uniform thickness friction plate 5 all is set to its thickness from the middle structure that reduces gradually to two end part.Camshaft 6 is installed in the hole of braking bottom board 2.
Compare with the traditional braking device, punching weldering break has following advantage:
1, retardation efficiency is high
(1) adopt increasing S-cam axle, the shortening braking response time, retardation efficiency can improve about 5%, and the corner deposit reaches 100 degree, reduces and adjusts arm adjustment number of times, and be that the wear-thickness that improves friction plate is laid a good foundation;
(2) the exclusive pliability of punching weldering shoes can improve the area of contact of friction plate and brake drum, thereby improves retardation efficiency.
2, light-weight design, effectively loss of weight
(1) adopts high-strength steel sheet, in conjunction with advanced punching press, welding procedure, guarantee to rush weldering type shoes and both had enough intensity, the advantages such as lightweight are arranged again, compare manufacturing efficiency with the casting shoes and improve more than 3 times, be particularly suitable for producing in enormous quantities;
(2) around punching weldering shoes structure, optimal design braking bottom board and annex;
COMPREHENSIVE CALCULATING is cast break loss of weight about 20% but rush the weldering break, i.e. single loss of weight 3Kg.
3, adopt not uniform thickness friction plate
There is the shortcoming that the wearing and tearing storage level is little, residual volume is large in traditional uniform thickness friction plate, and stock utilization is about 40%, and customer using cost is high, and has caused the huge wasting of resources and environmental pollution.
After adopting not the uniform thickness friction plate, the friction material of equivalent weight, can prolong 50% working life, and stock utilization improves more than 25%, but decrease user's user cost, social benefit is obvious.
4, anti-vibration is good
The distinctive excellent toughness of punching weldering shoes, noise and vibration in the time of can effectively alleviating braking.Use for a long time proof through a vapour, Yangze river and Huai river, punching weldering break to alleviate lorry persistent ailment-brake is shaken with sideslip positive effect.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
