Abstract
The invention relates to an elastic sandwich brake shoe device, which consists of a friction block, a heat-insulating ceramic layer, a vulcanized rubber layer and a shoe seat, wherein the heat-insulating ceramic layer is formed on the upper part of the friction block; the vulcanized rubber layer is formed on the upper part of the heat-insulating ceramic layer; and the shoe seat is arranged on the upper part of the vulcanized rubber layer. Compared with the prior art, the invention has the advantages that: braking can be performed continuously, and longer service life and higher safety are achieved; a synthetic material is taken as the friction block, so that friction noise caused by contact with a track can be lowered; meanwhile, high-frequency vibration of friction can be absorbed effectively by the rubber layer, so that the friction noise is further lowered; and furthermore, unevenness of a braking friction pair caused by various reasons is compensated greatly.
Description
Technical field
The invention belongs to the track traffic equipment technical field, especially relate to a kind of elasticity sandwich brake block device.
Background technique
As the employed brake block of conventional rails vehicular traffic; The general mode that adopts tread brake or disc braking; Because of the brake shoe friction area little; Most of heat load is born by wheel or brake disc; Heat is unfavorable for quick dissipation; When car such as tread brake; The wheel tread temperature increases rapidly; When arriving to a certain degree; Will make tread wear; Crackle or peel off has both influenced and has also influenced traffic safety working life, as adopting the mode of disc braking; Heat is unfavorable for dissipating fast and being accumulated in brake disc equally; Wheel shaft; On the bearing, be inappropriate for vehicle length and implement braking continuously apart from descending.What the brake block of general small-sized rail vehicle adopted is plane or watt shape structure that cast iron or other materials are processed; In the car brakeing process; Car braking noise is big, be prone to produce spark, brake shoe is nonelastic; Fragile when moving on the line; Working life is short, and corresponding friction pair is not had self-control and adaptive capacity.
Therefore in the time of will considering rail vehicle length apart from descending higher safety in operation is arranged, when guaranteeing to implement car brakeing continuously, also will guarantee the Security of higher riding comfort and contained equipment.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of elasticity sandwich brake block device that can implement to brake and have higher working life and Security continuously to be provided.
The object of the invention can be realized through following technological scheme:
A kind of elasticity sandwich brake block device; It is characterized in that; This device is made up of brake pad, thermal insulation ceramics layer, vulcanized rubber layer and brake shoe seat; Described thermal insulation ceramics layer is located at the top of brake pad; Described vulcanized rubber layer is located at the top of thermal insulation ceramics layer, and described brake shoe seat is located at the top of vulcanized rubber layer.
The length of described brake pad is 100～300mm, and width is 50～150mm.
Described thermal insulation ceramics layer is a net formula thermal insulation ceramics layer, and length is identical with brake pad with width, and thickness is 15～30mm.
Described vulcanized rubber layer is provided with 2～4 rows along its length, and broad ways is provided with 1～2 row, and the length of vulcanized rubber layer is identical with brake pad with width, and thickness is 20～50mm.

The brake shoe seat that described brake shoe seat is a heat radiating fin structure, this brake shoe seat are provided with two strong points with the linkage structure interface.
The resiliently deformable of described elasticity sandwich brake block device is 0～15mm.
Compared with prior art; The present invention adopts composite as brake pad; Friction noise when the ability reduction contacts with track; Can absorb the dither of friction simultaneously effectively through rubber layer; Further reduced friction noise, simultaneously to brake friction pair because the injustice that causes of a variety of causes has very strong compensating action.Because the heat that produces during friction concentrates between brake pad and the track; Brake pad and thermal insulation ceramics can be effectively with between heat obstruct and composite brake shoe and the tracks; Make among heat energy is melt into atmosphere fast along track; Protected vehicle arrangement preferably; Be applicable to that length apart from down hill braking, provides higher vehicle operating Security.Adopt the vehicle of this brake shoe structure, can adapt to the needs of sightseeing, chemical industry, oil, forest, colliery vehicle better.
