Description
Technical field
The utility model relates to a kind of motor spring brake repair room.
Background technology
At present truck, the piston type brake application by spring chamber of generally using in the motorcoach mainly is made up of energy storage cylinder block and coupled centre housing and front case, in cylinder body, be provided with the energy storage piston, the energy storage piston is divided into cylinder body calm the anger chamber and energy storage chamber again, be provided with energy storage spring and stay-bolt in the energy storage chamber, air-breathing and the expiration that the energy storage chamber produces when the energy storage piston up-down is to be communicated with by the braking return cavity in breathing pipe and the front case, centre housing is divided into brake chamber and the chamber of calming the anger with brake repair room, the brake application by spring chamber of this structure, because the braking return cavity contacts with extraneous, straight-through atmosphere, so, at glancing impact, respiration tracheae sucks dust and silt easily, damages cylinder arm and seal ring in the energy storage chamber easily, cause between cylinder and the piston and leak gas, influence braking effect and service life.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design at the existing shortcoming of above-mentioned brake repair room, the brake application by spring chamber of good braking effect.
In order to achieve the above object, the utility model is mainly realized by the following technical solutions.The utility model mainly is made up of the energy storage cylinder block of brake application by spring chamber coupled centre housing and front case, is provided with the energy storage chamber in the energy storage cylinder block, is provided with energy storage spring and stay-bolt in the energy storage chamber, and stay-bolt connects the energy storage piston.The end of stay-bolt is placed in the piston conduit of being located on the energy storage piston, is provided with the brake chamber intake interface and the chamber interface of calming the anger on centre housing, is provided with the braking epithelium between centre housing and the front case, is held tightly fixing by anchor ear.Centre housing is divided into brake chamber and the chamber of calming the anger with air cavity, is provided with the braking return cavity in front case, is provided with braking push-plate and braking push-plate pull back spring in the braking return cavity.The end of described piston conduit is provided with blind nut, and blind nut is provided with seal ring and blind nut air extractor vent, is provided with the conduit air extractor vent on piston conduit, between blind nut and conduit, be provided with blind nut before seal ring behind seal ring and the blind nut.Seal ring behind seal ring and the conduit before between piston conduit and centre housing, being provided with conduit.
The utility model compared with prior art has following tangible advantage and innovation.(1) respiration in energy storage chamber is walked around seal ring by blind nut aperture and conduit aperture, communicate by conduit and brake chamber, brake chamber communicates by brake activation valve and atmosphere at glancing impact not, and brake activation valve has the good dust-proof effect, can guarantee the breathing cleaning in energy storage chamber.(2) removed the breathing pipe of energy storage chamber, be difficult for entering dust, silt in the energy storage chamber, prolonged the service life of energy storage piston greatly, improved the system reliability with the braking return cavity.
The utility model is applicable to truck, motorcoach.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
