Abstract
The utility model discloses an electronic control auxiliary brake system comprising a main brake valve, a relay valve and a brake compartment, wherein gas output by a gas source is divided into two paths; one path is connected with the gas inlet end of the main brake valve through a first gas pipe, and the other path is connected with the gas inlet of the relay valve through a second gas pipe; the gas outlet end of the main brake valve is connected with the control port of the relay valve through a first gas outlet pipe; the gas outlet port of the relay valve is connected with the brake compartment through a second gas outlet pipe. The electronic control auxiliary brake system is characterized in that another path of the gas output by the gas source is connected with the gas inlet hole of an electromagnetic valve through a third gas pipe; the gas outlet hole of the electromagnetic valve is connected with the control port of the relay valve through a third gas outlet pipe; and the electromagnetic valve and a power supply switch are connected in series with each other and are connected with a power supply. The electronic control auxiliary brake system has the beneficial effects that: as the electromagnetic valve is connected in parallel between the main brake valve and the relay valve and gas in and out of the electromagnetic valve is controlled by switching on and off the electromagnetic valve, the overall brake performance is improved, and the overall auxiliary brake effect is realized.
Description
Technical field
The utility model relates to a kind of electric-control auxiliary brake system, belongs to the car load brake field.
Background technology
The used brake system of present most of automobile is a split brake system.Though the split brake system safety performance is than higher, the another one system is interference-free when one of them system breaks down.If but service braking system breaks down, though emergency brake system can play the emergency brake effect, but replaced not the action effect of service braking system fully, having must be dangerous.
Summary of the invention
In order to overcome the deficiency of above split brake system technology, the utility model provides a kind of electric-control auxiliary brake system that can improve car load service brake performance.
To achieve these goals, the utility model adopts following technical scheme:
A kind of electric-control auxiliary brake system comprises braking main valve, relay valve and braking locellus, the gas of source of the gas output; First tracheae of wherein leading up to connects braking main valve inlet end; Another road connects the relay valve admission port through second tracheae, and braking main valve outlet side first freeing pipe connects relay valve control mouth, and the relay valve air extractor duct connects the braking locellus through second freeing pipe; It is characterized in that: the gas of source of the gas output; The 3rd tracheae of leading up in addition connects an electromagnetic valve induction opening, and the electromagnetic valve air gate connects relay valve control mouth through the 3rd freeing pipe, and electromagnetic valve is connected each other with source switch and linked to each other with power supply.
Among the utility model embodiment, electromagnetic valve is a two position three-way valve.
The beneficial effect of the utility model:
Whether parallelly connected electromagnetic valve between braking main valve, the relay valve passes in and out gas UNICOM by electromagnetic valve break-make electric control electromagnetic valve, has improved braking performance of vehicle, has realized the effect of car load auxiliary braking.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details, following explanation only is exemplary, does not limit the protection domain of the utility model.
With reference to accompanying drawing 1, a kind of electric-control auxiliary brake system comprises braking main valve 1, relay valve 2 and braking locellus 3; The gas of source of the gas output, first tracheae 6 of wherein leading up to connects braking main valve 1 inlet end, and another road connects relay valve 2 admission ports through second tracheae 10; Braking main valve 1 outlet side first freeing pipe 7 connects relay valve 2 control mouths; Relay valve 2 air extractor ducts connect braking locellus 3 through second freeing pipe 9, the gas of source of the gas output, and the 3rd tracheae 11 of leading up in addition connects an electromagnetic valve 4 induction openings; Electromagnetic valve 4 air gates connect relay valve 2 control mouths through the 3rd freeing pipe 8, and electromagnetic valve 4 is connected each other with source switch 5 and linked to each other with power supply.When first freeing pipe 6 or braking main valve 1 when breaking down, can turn on the power switch 5, realize braking functions through the 3rd freeing pipe 11 control relay valves 2.
In the practice, electromagnetic valve 4 is a two position three-way valve.
The utility model control principle is: under normal circumstances; Source switch 5 breaks off; Braking main valve 1 works, and pressurized air realizes the running braking function of car load via first tracheae, 6-the first freeing pipe, 7-the second tracheae, 10-the second freeing pipe 9-braking locellus 3; When braking main valve 1 lost efficacy; Can turn on the power switch 5 this moment; Make the 3rd tracheae 11 and 11 conductings of the 3rd tracheae, pressurized air is via the 3rd tracheae 11-the three freeing pipe 8-relay valve 2 control mouthful-second freeing pipe 9-braking locellus 3, thus realization car load running braking function.
The utility model electric-control auxiliary brake system has improved braking performance of vehicle.
