Description
Technical field
The utility model relates to automobile pneumatic braking system technical field more particularly to a kind of quick systems for double rear bridge vehicles
Dynamic system.
Background technique
As national centering heavy type commercial vehicle operational safety technical requirements are higher and higher, when the response of Pneumatic braking system
Between and its antero posterior axis harmony it is most important.After double for bridge vehicles, due to rear axle apart from main brake valve farther out, driving system
It needs to supply to four brake chambers when dynamic, gas consumption is very big, therefore its braking response time relatively preceding bridge is longer, emergency braking
When vehicle be easy to happen " nodding " phenomenon.Therefore, the braking response time for how shortening rear axle, make front-rear axle brake synchronous, at
For those skilled in the art's urgent problem to be solved.
Based on the above considerations, the utility model devises a kind of fast braking system for double rear bridge vehicles.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of quick system for double rear bridge vehicles
Dynamic system.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model are as follows:
The utility model discloses a kind of fast braking systems for double rear bridge vehicles, including rear axle gas receiver, rear axle
Brake control valve and foot brake valves, the input port of the rear axle brake control valve and rear axle gas receiver are connected by the first pipeline
Logical, two delivery outlets of the rear axle brake control valve pass through the second pipeline respectively and are connected to middle rear axle brake chamber；The foot
One end of brake valve is connected to by third pipeline with rear axle gas receiver, and the other end is connected by the 4th pipeline and rear axle brake control valve
It is logical.
The input port of the rear axle brake control valve and rear axle gas receiver are by two first pipeline connections, and described two pieces the
One end of one pipeline is connected to and parallel with one another with rear axle gas receiver, and the end of two first pipelines passes through fast joint and closes
And it is connected to afterwards with the input port of rear axle brake control valve.
First pipeline is the pipeline that caliber is 16mm.
The end of two second pipelines is connected to the middle part of the 5th pipeline, and the both ends of the 5th pipeline are in
The connection of rear axle brake chamber.
Second pipeline is the pipeline that caliber is 16mm；Third pipeline and the 5th pipeline are the pipeline that caliber is 12mm；
4th pipeline is the pipeline that caliber is 8mm.
The utility model has the beneficial effects that:
1. the utility model is by the control gas source of foot brake valves and the gas supply gas source of rear axle brake control valve from rear axle
Gas receiver directly takes gas, effectively gas source is avoided to shunt；
2. the utility model realizes that Double Data Rate is supplied to brake chamber by two first pipeline parallel connections, effectively shorten double
The response time of rear axle braking, shorten braking distance, improves vehicle security.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 rear axle gas receiver, 2 rear axle brake control valves, 3 foot control valves, 4 first pipelines, 5 second pipelines, 6 thirds
Pipeline, 7 the 4th pipelines, 8 the 5th pipelines.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Referring to Fig. 1.
The utility model discloses a kind of fast braking systems for double rear bridge vehicles, including rear axle gas receiver 1, rear axle
Brake control valve 2 and foot brake valves 3, the input port of the rear axle brake control valve 2 and rear axle gas receiver 1 pass through the first pipeline
4 connections, two delivery outlets of the rear axle brake control valve 2 pass through the second pipeline 5 respectively and are connected to rear axle brake chamber；It is described
One end of foot brake valves 3 is connected to by third pipeline 6 with rear axle gas receiver 1, and the other end is controlled by the 4th pipeline 7 and rear axle braking
Valve 2 processed is connected to, and the control gas source of foot brake valves 3 and the gas supply gas source of rear axle brake control valve 2 directly take from rear axle gas receiver 1
Gas effectively avoids gas source from shunting.
The input port of the rear axle brake control valve 2 is connected to rear axle gas receiver 1 by two first pipelines 4, and described two
One end of the first pipeline of root 4 is connected to and parallel with one another with rear axle gas receiver 1, and the end of two first pipelines 4 passes through quick
Connection-peg is connected to after merging with the input port of rear axle brake control valve 2, and fast joint is that existing F type is quick in the present embodiment
Connection-peg realizes that Double Data Rate is supplied to brake chamber by the way that two first pipelines 4 are in parallel, the sound that double rear axles that effectively shorten are braked
Between seasonable, shorten braking distance, improves vehicle security.
The end of two second pipelines 5 is connected to the middle part of the 5th pipeline 8, the both ends difference of the 5th pipeline 8
It is connected in middle rear axle brake chamber.
First pipeline 4 is the pipeline that caliber is 16mm, and domestic brake system pressure maintains 1MPa or so, and caliber is most
It is 16mm greatly, by the way that the brake piping of maximum caliber is arranged, lifting system pressure improves the Pneumatic braking system response time.
