The brake block is made by the composing of at least a friction material, namely, the surface of the brake block consists of more than two friction materials; for example, the surface of the brake block is provided with a material which issuitable for a wet and slippery environment and the other material which is suitable for a dry environment relatively; therefore, the friction materials can be applied to the brake block independently or in combination; due to the unique advantage of each friction material, the invention can be suitable for various driving conditions.
Description
Technical field
The present invention relates to a kind of disk brake block, especially a kind of multiple material disk brake block that merges multiple friction material and the multi-functional use of tool, and the manufacturing process of making this multiple material disk brake block.
Background technique
Disk brake block commonly used is made by single friction material, has relatively limited the function of brake block, and can't positively bring into play its best braking effect; For example, if adopt the brake shoe of metal material entirely, so because of the higher braking effect of its hardness can promote and high temperature resistant, but meeting thereby the shortcoming that produces noise and attack disc; Vice versa, if will suppress noise in the use, then the abrasion effect of brake block will reduce; Perhaps, anti-slip effect is fine under wet and slippery state of rainy day, but is not suitable for using in dry environment, and hence one can see that does not have a kind of single material can be suitable for various travelling states in the service brake sheet at present.
The past industry is all used the fiber material in a large number, its usefulness in refractoriness and abrasion degree is all not high, and the high temperature that friction produces under long-time the use, can be because of disperseing to produce the accumulation of heat phenomenon, cause excess temperature depletion (Fade) that braking effect is run off rapidly, be behind the excess temperature braking efficiency reduce in addition failure phenomenon obvious, therefore then need change based on metal material.
If only then can have preferable thermal conductivity with single metal material, can help the dispersion of heat, and high temperature can not produce vaporization and excess temperature depletion (Fade) failure phenomenon, but the high temperature that will produce because of rubbing passes to and causes the brake oil boiling that brake was lost efficacy on the actuating plunger, therefore also causes the hidden danger on the safety.
Summary of the invention
At the problem that prior art exists, main purpose of the present invention provides the disk brake block of the multiple friction material of a tool, and brake block can be used in various environment.Secondary objective of the present invention provides a kind of disk brake block of tool heat-proof device design, in order to reduce the thermoconvection conduction between brake block and piston extension bar.The 3rd purpose of the present invention provides a kind of combination of brake block material, in order to strengthen the degree of combining closely of brake block.The 4th purpose of the present invention be limited piston with brake disc between the area that contacts, in order to reducing transmission of heat to piston, and the groove that sees through the brake disc surface improves the cross-ventilation of brake block and piston space, reduces the transmission of heat of piston and brake block thus.The 5th purpose of the present invention provide one kind of multiple friction materials in conjunction with flow process, in order to strengthen the degree of combining closely of brake block and brake disc.
For reaching above-mentioned target, multiple material disk brake block of the present invention has been improved the design of often knowing, the present invention compares with the structure effect of often knowing technology:
1, multiple material disk brake block of the present invention, it utilizes the design of the multiple friction material of combination can reach effect multi-functional and that use in various driving situations, it has improved the single friction material of service brake sheet, and it can only be used for the shortcoming of single environment.
2, multiple material disk brake block of the present invention, the structural design of the heat insulation effect of its tool can reach the purpose that effective reduction brake block hot-fluid conducts, and the variable shortcoming that lost efficacy because of brake block is overheated with structure.
The invention provides that a kind of solution is above-mentioned commonly uses structure problem and reach perfect simultaneously and take into account the invention of security purpose.
Brake block of the present invention makes the abrasives of disk brake block reach perfect adaptation on performance, durability, noise, it is at least by compound the making of a kind of friction material, represent that promptly the surface of brake block is made up of the friction material more than two kinds, there is a material to be suitable for wet and slippery environment another kind as the brake block surface and then is suitable for dry environment, therefore these materials can be applied on the brake block separately, unique advantage by utilizing each friction material to provide makes the present invention can be suitable for various brake situation.
