Abstract
The utility model discloses a truck braking system aerifys gas circuit device outward, it is main by tee pipe coupling, check valve with take the quick connector of check valve to constitute, the gas of air compressor output takes the quick connector one end of check valve to be connected with the tee pipe coupling through check valve, four return circuit protective valves of tee pipe coupling input, and the other end is connected with outside air supply, four return circuit protective valves aerify for braking system's gas cylinder. When engine broke down, air compressor stopped the air feed, and the air feed of realizing right braking system is connected to outside air supply through the quick connector with taking the check valve. The utility model discloses a there is sufficient brake force at the vehicle draging the in -process to the effectual possibility of having avoided the traffic accident emergence has improved car driving safety.
Description
Technical field
The utility model belongs to automobile technical field, relates to auto-safety mechanism, particularly relates to a kind of truck brake system and inflates gas path device outward.
Background technology
Along with socioeconomic development, the application of truck is more and more extensive, as more and more prosperous stream carrier vehicle, and slag-soil truck, waste-skip that urban environmental protection requires, the Mixer Truck of urban infrastructure demand, indispensable dumping car in mine etc.Along with the growth of number of truck, the problem in its use procedure also continues to bring out, and as travelled the truck et out of order in way, need drag it to repair plant maintenance, and in its dragging process, there is potential safety hazard, the traffic accident caused due to this reason is very common.Reason is truck brake system is adopt air pressure to control, pneumatic supply is from the air compressor of driven by engine, and once driving engine does not work, pneumatic supply will disappear, air pressure in brake system will lose braking effect after braking operation several times, and now braking during standstill will locking wheel, vehicle cannot be travelled, in order to can vehicle be dragged, just braking during standstill must be removed, and now because service brake was also lost efficacy, though vehicle can drag, but brakeless, because truck quality comparation is large, once drag, self does not brake again, be easy to collide with front truck, cause traffic accident.
Utility model content
The purpose of this utility model is to provide a kind of truck brake system and inflates gas path device outward, solves the problem of braking failure when causing dragging because truck brake system pneumatic supply lost efficacy.
The technical solution of the utility model is: a kind of truck brake system inflates gas path device outward, it is characterized in that: the quick connector primarily of tee connection, check valve and band check valve forms; The gas that air compressor exports is through check valve, tee connection input four-loop protection valve, and quick connector one end of band check valve is connected with tee connection, and the other end is connected with external air source; Four-loop protection valve is to the inflating gas cylinder of brake system.
Beneficial effect: the utility model has the advantage of, provide a kind of truck brake system and inflate gas path device outward, solve the generation of braking failure when causing dragging because truck brake system pneumatic supply lost efficacy, thus actv. avoids the possibility that traffic accident occurs, improve traffic safety when truck drags, and this apparatus structure is simple, be easy to realize, low price.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of gas circuit of truck brake system;
Fig. 2 is outer inflation gas circuit schematic diagram of device of the present utility model.
Detailed description of the invention
For making the purpose of this utility model, content and advantage clearly, below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.
Be illustrated in figure 1 truck brake system air-channel system; pneumatic supply is provided by air compressor; pressurized air drying device, four-loop protection valve are to the inflating gas cylinder of brake system; gas cylinder plays stored-gas and ensures the effect that system pressure is stable in brake system; and gas is distributed to relay valve and braking during standstill and service braking control valve; i.e. hand valve and foot valve, hand valve and foot valve realize inflation and the venting of compressed air brake cylinder by controlling relay valve, realize braking and the releasing of vehicle.
The utility model, based on above-mentioned truck brake system air-channel system, adds a kind of truck brake system and inflates gas path device outward between dryer and four-loop protection valve, and realizing external air source is inflating gas cylinder, thus the object of the system of guarantee air pressure.As shown in Figure 2, the quick connector primarily of tee connection, check valve and band check valve forms this device; The gas that dryer exports is through check valve, tee connection input four-loop protection valve, and quick connector one end of band check valve is connected with tee connection, and the other end is connected with external air source.Wherein the effect of check valve prevents gas acting in opposition in dryer and air compressor, avoids leaking; The effect of tee connection makes outer inflation gas circuit to be connected into brake line; The effect of the quick connector with check valve realizes external air source to be connected with brake line fast, and ensure that brake piping can not leak gas under normal circumstances.
When vehicle motor breaks down, air compressor stops air feed, and external air source is by being connected with the quick connector of band check valve the air feed realizing right brake system.
The utility model achieves has enough braking forces at vehicle in dragging process, thus actv. avoids the possibility that traffic accident occurs, and improves running safety.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
