Abstract
The utility model discloses an initiative heat dissipation dish device of stopping relates to brake equipment technical field. It includes brake disc, braking pincers, wheel cylinder, oil pipe, and the toper shower nozzle is installed at the top of braking pincers, and toper shower nozzle intercommunication has air duct, air duct and the pressure steel bottle intercommunication that contains liquid carbon dioxide, install the electromagnetic switch valve on the air duct, the export intercommunication of pressure steel bottle has the relief valve. The utility model discloses utilize the carbon dioxide gas ization cooling of can taking the initiative, be favorable to improving the life of brake disc, stop maintaining good's braking effect of messenger's dish.
Description
Technical field
The utility model relates to braking device technical field.
Background technique
It is disk type brake device that dish is stopped, and cries disc brakes again, as the term suggests be get its shape and gain the name.It is by hydraulic control, and main parts size has brake disc, wheel cylinder, brake calipers, oil pipe etc.
Alloy steel for braking discs manufacture is also fixed on wheel, with vehicle wheel rotation.The base plate that wheel cylinder is fixed on break maintains static.Two friction plates on brake calipers are contained in the both sides of brake disc respectively.The hydraulic pressure that the piston of wheel cylinder transports by oil pipe, promote friction plate and press to brake disc generation friction catch, it just looks like the plate vised with pliers in rotation that action is got up, and forces it to stop the same.
Brake disc is because friction, and generating heat will cause Material Strength to reduce after uniform temperature, affects the life-span of braking effect and brake disc.
Model utility content
Technical problem to be solved in the utility model, be the technical deficiency for above-mentioned existence, provide a kind of dynamic cooling brake disc brake apparatus, it utilizes carbon dioxide gasification can carry out active cooling, be conducive to the working life of improving brake disc, dish stopped and maintains good braking effect.
The technical solution adopted in the utility model is: provide a kind of active heat removal dish brake apparatus, comprise brake disc, brake calipers, wheel cylinder, oil pipe, the top of brake calipers is provided with Conic nozzle, and Conic nozzle is communicated with air pipe, and air pipe is communicated with the pressure steel cylinder filling liquid carbon dioxide; Air pipe is provided with electromagnetic switch valve; The outlet of pressure steel cylinder has Decompression valves.
Further optimization the technical program, the interior muscle of the brake disc of active heat removal dish brake apparatus is helical radiation shape.
Further optimization the technical program, the outer side surface of the brake disc of active heat removal dish brake apparatus is provided with pentagonal line.
The beneficial effects of the utility model are: 1, good cooling effect.Carbon dioxide is directly sprayed onto in chamber, brake disc air channel from Conic nozzle, during liquid carbon dioxide gasification, absorbs amount of heat, can reduce the temperature of brake disc rapidly, and again brake disc can not form liquid film, affects braking effect.2, in helical radiation shape, muscle, when brake disc rotates, produces larger centrifugal force, is conducive to the circulation fast of air, improves the radiating effect of brake disc; 3, pentagonal line can better be cleared up because of dust fricative with brake calipers on brake disc, and is finally fallen apart in air by marking groove, thus avoids the rolling friction because there being dust to produce, and adds the frictional force between brake disc and brake calipers; When the rainy day travels, pentagonal line makes the surface irregularity of brake disc, can effectively avoid Water film lubricating effect, travels the air film that equally can alleviate air and produce, thus improve braking effect at fine day.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Conic nozzle application state schematic diagram;
Fig. 3 is the structural representation of interior muscle.
In figure, 1, brake disc; 2, brake calipers; 3, wheel cylinder; 4, oil pipe; 5, Conic nozzle; 6, air pipe; 7, pressure steel cylinder; 8, electromagnetic switch valve; 9, Decompression valves; 10, interior muscle; 11, pentagonal line.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, active heat removal dish brake apparatus, comprises brake disc 1, brake calipers 2, wheel cylinder 3, oil pipe 4, and the top of brake calipers 2 is provided with Conic nozzle 5, and Conic nozzle 5 is communicated with air pipe 6, and air pipe 6 is communicated with the pressure steel cylinder 7 filling liquid carbon dioxide; Air pipe 6 is provided with electromagnetic switch valve 8; The outlet of pressure steel cylinder 7 has Decompression valves 9; The interior muscle 10 of brake disc 1 is helical radiation shape; The outer side surface of brake disc 1 is provided with pentagonal line 11.
Conic nozzle 5 is positioned at the top of brake calipers 2, the position in corresponding brake disc 1 air channel of spout, when the road conditions down train of driver at frequently braking, open electromagnetic switch valve 8(at the control switch driving indoor location electromagnetic switch valve 8, electromagnetic switch valve 8 directly uses Vehicular direct-current power supply), in Conic nozzle 5, the air channel of brake disc is sprayed at a high speed after liquid carbon dioxide gasification, by the heat absorption of brake disc 1 in the process of liquid carbon dioxide gasification, reduce the temperature of brake disc 1 rapidly.
Be not liquid carbon dioxide in pressure steel cylinder 7, also have the gaseous carbon dioxide of partial gasification, the effect of Decompression valves 9 prevents the pressure in pressure steel cylinder 7 excessive and explosion caused.
In helical radiation shape, muscle 10 is when brake disc 1 rotates, and produces larger centrifugal force, is conducive to the circulation fast of air, improves the radiating effect of brake disc 1; Pentagonal line 11 can better be cleared up because of dust fricative with brake calipers 2 on brake disc 1, and is finally fallen apart in air by marking groove, thus avoids the rolling friction because there being dust to produce, and adds the frictional force between brake disc 1 and brake calipers 2; When the rainy day travels, pentagonal line 11 makes the surface irregularity of brake disc 1, can effectively avoid Water film lubricating effect, travels the air film that equally can alleviate air and produce, thus improve braking effect at fine day.
