Abstract
The utility model discloses a brake piece having high temperature resisting and heat insulating functions. The brake piece is characterized in that a high temperature resisting and heat insulating layer (2) is added on one side of a friction material (3) close to a steel backing plate (1). High temperature produced by a brake system in working is transferred to the steel backing plate through the high temperature resisting and heat insulating layer and then heats brake liquid through a piston, and overhigh temperature is prevented from being produced. The brake piece overcomes the shortcomings including easy high temperature loss, low work efficiency, poor safety performance and the like, has the advantages of being high temperature resisting, long in service life, safe and the like, and greatly improves economic benefit.
Description
Technical field
The utility model relates to the braking equipment of a kind of work (agriculture) industry machinery use, specifically a kind of braking plate (brake block) with work (agriculture) industry machinery use of high temperature resistant heat insulation function.
Background technique
At present, on the market engineering machinery braking plate is comprised of steel backing and liner (friction material).The groundwork of liner is partly friction material.There is following shortcoming in existing engineering machinery braking plate: 1. product performance are unstable: the braking plate material capability that has is poor, and wear rate is large, and noise is also large; Some braking plate performances are fabulous, but price is surprising, and cost is too high; 3. high temperature problem: most of braking plate is in braking system in the frequent or process that works long hours, easily produce high temperature, thereby accelerated the aging and damage of braking equipment, braking ability is descended, appearance braking force weakens even malfunctioning, brings hidden danger for the complete machine job safety.4. cooling problem: for the brake fluid that occurs in engineering machine in working process " high temperature " problem, all generally the cooling of stopping now, affected working efficiency, and individual other adopts the cold water forced cooling, the high and low temperature alternative effect, brake disc will produce " metal fatigue ", the invisible crackle of many naked eyes occurs, and hidden danger easily causes the accident.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that overcomes background technique, has increased a high temperature resistant heat insulation layer, has effectively solved " high temperature problem " that produce in the braking system braking process, has greatly improved working efficiency, has reduced potential safety hazard.
Technical solution adopted in the utility model is: the side at the close steel backing of friction material has increased a high temperature resistant heat insulation layer, and the thermal-protective coating main raw material(s) is Foaming of phenolic resin (particle).The thermal-protective coating formula is: Foaming of phenolic resin (particle) 47%, glass fibre 10%, ceramic fiber 10%, phenol-formaldehyde resin modified 21%, friction powder 10%, grey aluminium oxide 2% etc.After thermal-protective coating was pressed the formula batch mixing, first cold moudling was standby.First add the heat insulation layered material of cold moudling in pressing process, then add the top layer material, by hydraulic press, by technical requirements, hot-press solidifying moulding under certain temperature, time, pressure-acting.Semi-finished product after hot pressing guarantee that through the further solidifying of heat treatment oven the performance of friction material reaches the regulation requirement.Product after heat treatment is slotted according to drawing requirement and technical standard, surface treatment, and the finished product that the outward appearance physical dimension meets standard-required is processed in polishing.The increase of high temperature resistant heat insulation layer, the high temperature that has produced when having prevented braking work is transmitted to steel backing.
Steel Backing Plate of the present utility model is rectangular, and the thickness of high temperature resistant heat insulation layer is 4 millimeters.
The beneficial effects of the utility model are: 1, the utlity model has good effect of heat insulation, the high temperature that when thermal-protective coating has effectively prevented braking, brake disc produces is transmitted to steel backing, and then heat brake fluid by piston, prevented that brake fluid is aging, may make the brake fluid boiling when preventing excess Temperature or produce gas and then destroy braking ability, guarantee the normal reliable operation of engineering machinery, improved working efficiency.2. the utility model thermal-protective coating can effectively reduce the Sealings such as brake calipers because of high temperature ageing, and the material selectable range of Sealing is wider, can reduce costs.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is structure principle chart of the present invention, and it has increased a high temperature resistant heat insulation layer (2) in a side of the close Steel Backing Plate (1) of friction material (3) as shown in the figure, is a groove (4) in the middle of friction material (3).
Working principle of the present utility model is: in braking process, friction material (3) is transmitted to Steel Backing Plate (1) through high temperature resistant heat insulation layer (2), and then heat brake fluid by piston, due to the effect of heat insulation of high temperature resistant heat insulation layer (2), effectively solved " high temperature " problem that occurs in the braking system braking process.
Claims (4)
1. braking plate with high temperature resistant heat insulation function is characterized in that: it has increased a high temperature resistant heat insulation layer (2) at friction material (3) near a side of Steel Backing Plate (1).
2. the braking plate with high temperature resistant heat insulation function according to claim 1 is characterized in that: described Steel Backing Plate (1) is rectangular.
3. the braking plate with high temperature resistant heat insulation function according to claim 1, it is characterized in that: described high temperature resistant heat insulation layer (2) thickness is 4 millimeters.
