Beneficial effect:
The utility model spring energy-storage emergency brake system structure is simple, practical, can realize vehicle and cannot start to walk lower than vehicle during service brake air pressure, simultaneously when the main line of giving vent to anger of automobile air compressor breaks down, can remove braking during standstill easily, carry out trailer.The present invention is applied on passenger vehicle, can obviously promote the safety performance improving passenger vehicle, avoid some unnecessary safety misadventures to occur, also mitigate chaufeur because motor vehicle braking system, without gas, needs to climb to the danger and worries of removing the screw rod split out on spring energy-storage air chamber at the bottom of car.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spring energy-storage emergency brake system.
Detailed description of the invention
As shown in Figure 1; the utility model spring energy-storage emergency brake system, comprises separating switch 1, double-way check valve 2, hand brake valve 3, air receiver for subsequent use 4, four-loop protection valve 5, rear braking during standstill rapid release valve 6, dryer 7, Air compressor 8 and spring energy-storage compressed air brake cylinder 9.
The admission port of this separating switch 1 is connected to air receiver 4 for subsequent use by tracheae, and the air extractor duct of this separating switch 1 is connected to double-way check valve 2 by tracheae.
This double-way check valve 2 is T-shaped structure, and its transverse ends is admission port A, B, and longitudinal one end is air extractor duct C; Wherein, the admission port A of this horizontal one end of double-way check valve 2 is connected to four-loop protection valve 5 by tracheae, and the admission port B of the horizontal other end is connected to the air extractor duct of separating switch 1 by tracheae, and longitudinal one end air extractor duct C is connected to hand brake valve 3 by tracheae.
The admission port of this hand brake valve 3 is connected to the air extractor duct C of double-way check valve 2 by tracheae, the air extractor duct of this hand brake valve 3 is connected to the admission port of rear braking during standstill rapid release valve 6 by tracheae.
The air extractor duct of this air receiver 4 for subsequent use is connected with the admission port of separating switch 1, provides source of the gas to separating switch 1, and meanwhile, the admission port of this air receiver 4 for subsequent use is also connected with check valve 41 and is connected with four-loop protection valve 5 by check valve 41.
This four-loop protection valve 5 has a pair air extractor duct and an admission port, one of them air extractor duct of this four-loop protection valve 5 is connected with the admission port A of double-way check valve 2 by tracheae, another air extractor duct of this four-loop protection valve 5 is connected to the check valve 41 of air receiver 4 for subsequent use by tracheae, gas can only flow to air receiver 4 for subsequent use from four-loop protection valve 5; The admission port of this four-loop protection valve 5 is connected to dryer 7 by tracheae.
This rear braking during standstill rapid release valve 6 has an admission port and a pair air extractor duct, the admission port of this rear braking during standstill rapid release valve 6 is connected with the air extractor duct of hand brake valve 3, and a pair air extractor duct of this rear braking during standstill rapid release valve 6 is connected to a pair spring energy-storage compressed air brake cylinder 9 respectively by tracheae; Wherein, this rear braking during standstill rapid release valve 6 is also connected with by stopping brake light switch 61.
Also be connected with condenser 71 between this dryer 7 and Air compressor 8, the admission port of this condenser 71 is connected by tracheae with the air extractor duct of Air compressor 8.
Of the present utility modelly realize principle:
Separating switch 1 is in normally off, and the air feed of braking during standstill passes through hand brake valve 3 directly to the pipeline air feed between spring energy-storage compressed air brake cylinder 9 by the air extractor duct of four-loop protection valve 5, removes braking during standstill; And when the air pressure in whole gas circuit service brake pipeline is lower than safe air pressure (450KPa), vehicle stops on the way, pull on hand brake valve 3, at this moment the air pressure of whole braking during standstill (hand brake valve 3 to spring energy-storage compressed air brake cylinder 9) and service brake pipeline all will lower than safe air pressure (450KPa).Hand brake valve 3 to spring energy-storage compressed air brake cylinder 9 air pressure is 0, and air pressure protection the pressure: >=500KPa of four-loop protection valve 5, therefore the air pressure of four-loop protection valve 5 to hand brake valve 3 is 500KPa.Now as hand brake valve 3 is unclamped in maloperation, then in the pipeline of four-loop protection valve 5 to spring energy-storage compressed air brake cylinder 9, air pressure is between 100-150KPa, and such air pressure cannot remove braking during standstill.At this moment service brake cisco unity malfunction, braking during standstill can not proper solution remove simultaneously; Driver can be avoided to get on the bus just be open to traffic by actv., meet emergency and to result in an automobile accident the possibility occurred.
The utility model structure design is simple, rationally, can promote the safety of passenger vehicle braking during standstill, realize vehicle when without service brake, vehicle can not play walking vehicle, thus avoids vehicle to occur accident because of maloperation.
