Abstract
The invention discloses a parking baseplate assembly of a drum-in-disc type parking brake, which comprises a baseplate body, a dust cover and a pulling-rope conduit arranged on the baseplate body, and the baseplate body, the dust cover and the pull conduit are made from engineering plastics or carbon fibers. Because the parts are made from the engineering plastics or the carbon fibers with high temperature resistance, corrosion protection, good weatherability and flame resistance to substitute metal materials used in the prior art, the cost of the materials and machining is lower; the weight of the parts is decreased; the problem of easy corrosion of the metal materials is solved while effectively meeting the requirements for the functions and the performance of the baseplate assembly of the drum-in-disc type parking brake; the process for producing the parts is simpler than the processes for pressing, welding and riveting the metal materials, and the like; the production cycle is shortened effectively; and the production efficiency is enhanced. Moreover, the parking baseplate assembly also has the effects on reducing noise and improving weatherability, and greatly enhances the stability of the braking performance of the parking brake.
Description
Technical field
The present invention relates to the braking during standstill parts of vehicle, drum-type Parking Brake parking baseplate assembly in particularly a kind of dish.
Background technology
Parking Brake typically refers to the hand-operated brake that power actuated vehicle is installed, and is called for short parking brake, is used for stablize vehicle after vehicle comes to a complete stop, when avoiding vehicle to stop on the road surface, slope owing to the slide car causes the accident.
In the prior art, the parking baseplate assembly of drum brake mechanism in the dish of vehicle mainly is to be made of parking baseplate, dust boot, stay cord guide plate, usually, they are by combining through welding or riveting process after the metallic plate punching moulding, carrying out the finish coatings anti-rust treatment at last again.Because parking baseplate assembly is that sheet metal component combines, and causes it to have following deficiency: punch forming and welding (riveted joint) complex process, cause process period long, production efficiency is low; Corrosion easily takes place in metal piece, makes the parking baseplate assembly antirust ability low; In addition, material and technology have determined that also drum brake mechanism in use easily produces abnormal sound in the dish, and productive costs is higher.
Therefore, need to explore the parking baseplate assembly of drum brake mechanism in a kind of dish, under the impregnable situation of performance, make its production technology obtain simplifying, the production cycle shortens, and production efficiency improves, productive costs reduces, and antirust ability improves, and makes it in use be difficult for producing abnormal sound.
Summary of the invention
In view of this, the invention provides drum-type Parking Brake parking baseplate assembly in a kind of dish, adopt the certain material manufacturing, to improve production efficiency, the antirust ability of parking baseplate assembly, and reduce its productive costs, simultaneously, make it in use be difficult for producing abnormal sound.
Drum-type Parking Brake parking baseplate assembly in the dish of the present invention comprises base plate plate body, dust boot and is arranged at stay cord conduit on the base plate plate body that described base plate plate body, dust boot and stay cord conduit are made by engineering plastics or carbon fibre.
Further, described base plate plate body, dust boot and stay cord conduit are made one;
Further, described base plate plate body upper edge is the uniform boss that is used to support brake shoe brake cheek that is provided with circumferentially, and described boss surface coating spray metal forms hardened layer;
Further, the fluted formation reinforced rib of punch forming on the described dust boot.
The beneficial effect of the invention: drum-type Parking Brake parking baseplate assembly in the dish of the present invention, comprise the base plate plate body, dust boot and the stay cord conduit that is arranged on the base plate plate body, described base plate plate body, dust boot and stay cord conduit are made by engineering plastics or carbon fibre, because each part has adopted high temperature resistant, corrosion prevention, good weatherability, and engineering plastics or carbon rope fiber with flame resistance replace metallic material used in the prior art, material and tooling cost are lower, parts weight saving, when effectively satisfying the function and performance requriements of drum-type Parking Brake parking baseplate assembly in the dish, solved the problem that metallic material is easy to corrosion, the technology of finished parts is with respect to the punching press of metallic material, technologies such as welding and riveted joint are also simpler, effectively shortened the production cycle, improved production efficiency, simultaneously, also play the effect of noise reduction and raising weather resisting property, improved the stability of drg performance of parking brake greatly.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A section drawing of Fig. 1.
The specific embodiment
Fig. 1 is a structural representation of the present invention, Fig. 2 is the A-A section drawing of Fig. 1, as shown in the figure: drum-type Parking Brake parking baseplate assembly in the dish of present embodiment, comprise base plate plate body 1, dust boot 2 and the stay cord conduit 3 that is arranged on the base plate plate body 1, described base plate plate body 1, dust boot 2 and stay cord conduit 3 are made by engineering plastics, because engineering plastics are high temperature resistant, corrosion prevention, good weatherability, and has flame resistance, with respect to metallic material used in the prior art, material and tooling cost are lower, parts weight saving, when effectively satisfying the function and performance requriements of drum brake mechanism in the dish, solved the problem that metallic material is easy to corrosion, the technology of finished parts is with respect to the punching press of metallic material, technologies such as welding and riveted joint are also simpler, effectively shorten the production cycle, improved production efficiency.Certainly, the similar carbon fibre of employing and engineering plastics performance and character replaces metallic material used in the prior art, can realize purpose of the present invention equally.
In the present embodiment, described base plate plate body 1, dust boot 2 and stay cord conduit 3 are made one, and production technology is simplified, and the integral type parking baseplate also helps reducing abnormal sound with respect to the compound type parking baseplate.
In the present embodiment, described base plate plate body 1 upper edge is circumferentially uniform to be provided with 6 boss 1a that are used to support brake shoe brake cheek, and coating spray metal, described boss 1a surface forms hardened layer, and boss surface hardness is improved, be damaged when avoiding boss to cooperate, improve the stability of performance of parking brake with brake shoe brake cheek.
In the present embodiment, the fluted 2a of punch forming forms reinforced rib on the described dust boot 2, to improve the intensity of dust boot.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
