3, the active handoff procedures of driving engine inflation pump and electric inflation pump
Inflation pump, also known as air compressor, its function mainly provides enough airline pressure for automobile air brake system, to ensure the safe and reliable of automobile air brake system.It is the device former dynamic mechanical energy being converted to gaseous tension energy, is compressed-air actuated pressure generator.The principle of work of driving engine inflation pump is, driving engine is by two V-belts or gear drive air pump bent axle, thus driven plunger is inflated, and the gas got imports air receiver by pipeline.Electricity inflation pump principle of work utilizes car load power supply to drive cylinder piston work by the running of motor.Driving engine inflation pump and the key distinction of electric inflation pump are that original kinetic energy is different, and driving engine inflation pump is mainly by the mechanical energy that engine operation drives, and electric inflation pump provides electric energy by car load power supply.Both character is identical, and the energy provides source different.
In hybrid power passenger car brake system described in the utility model, comprise engine power, pure electronic and hybrid power three kinds of car load power presentation modes.As can be seen from Figure 1, driving engine inflation pump 1 is connected with air dryer 3 with two inlet ends of electric inflation pump 2 respectively by double-way check valve 18, can be respectively car load and provide braking gas source.As shown in Figure 10, double-way check valve 18 comprises the first inlet end 181, second inlet end 182 and 183 3, outlet side port.When any one inlet end of double-way check valve 18 is opened, its outlet side 183 is just outwards vented.In the process of moving, chaufeur switches the braking gas source of car load from driver zone.
3.1 engine power
Under the surface conditions higher to power demand, main power source cuts out by chaufeur, disconnects the operation of electric inflation pump, makes car load be in fuel engines power driven.Now, car load braking is identical with traditional vehicle braking principle, provides source of the gas by driving engine inflation pump, and guarantee braking performance of vehicle is intact, completes each braking procedures such as front braking, rear braking, hand braking and auxiliary braking.
3.2 is pure electric-powered
When bus driving is at urban pavement, road surface is complicated and changeable, brake frequent not timing, and chaufeur by tail-off, namely selects engine off by full-vehicle control, makes car load be in pure motorized motions state.Now, car load braking is identical with pure electrodynamic braking principle, provides braking gas source by electric inflation pump, and guarantee braking performance of vehicle is intact, completes each braking procedures such as front braking, rear braking, hand braking and auxiliary braking.
3.3 hybrid power
Car load dual power source drives, the same hybrid power passenger car of principle.When driving engine runs into the various emergency situations such as Low oil Fuel, Air compressor damage, the electronic energy provides car load propulsion source.
4, the principle of work of relay valve and differential relay valve
As shown in figure 11, relay valve 11 handles brake response time and releasing braking time in gas circuit for shortening, and plays a part to accelerate and put soon.The principle of work of relay valve 11 is: during automobile normal running, and the pressurized air come from air receiver enters from 111 mouthfuls, and air intake valve 115 is closed, and drain tap 116 is opened, the 112 mouthfuls of logical air be connected with air chamber.When braking, the pressurized air come from brake activation valve enters the inner A chamber of relay valve from 114 mouthfuls, and make the descending closedown drain tap 115 of piston 117, pressurized air transfers to compressed air brake cylinder through 111 mouthfuls from 112 mouthfuls, and air intake valve when reaching balance, drain tap is closed simultaneously.When brake off, A chamber air pressure is zero, and piston 117 rises, and drain tap 116 is opened, and air intake valve 115 is closed, and air chamber air pressure is through 112 mouthfuls, and drain tap and exhausr port 113 enter air rapidly, play and put effect soon.
As shown in figure 12, under driving states, hand brake valve is continuous to A chamber air feed through 124-II mouthful.Piston a and piston b pressurized, close drain tap e, and it are downward to promote valve rod c downwards, open air intake valve d, the pressurized air come from air receiver by 121 mouthfuls is through 122 mouthfuls of outputs, and the spring brake chamber be connected with 122 mouthfuls thus be provided pressurized air, brake application by spring is removed.When service braking system single movement, and when handling main brake, pressurized air enters B chamber through 124-I mouthful, depressed by piston b, due to the antagonistic force in A chamber, C chamber, the work of pressure on differential type relay valve thus arriving B chamber there is no impact, pressurized air continues the brake application by spring part flowing to spring brake chamber, thus brake off, meanwhile, the pressurized air directly from tractor truck brake activation valve makes diaphragm portion again act on.When parking brake system single movement, and when handling hand brake valve, A cavity segment is all emptying.Piston a is not stressed, and the piston b being exposed to C cavity gas storage cylinder air pressure upwards pushes away, and drain tap e opens, and valve rod c rises simultaneously, closes air intake valve d.Like this, spring brake cylinder just according to the position of hand braking handle make gas through 122 mouthfuls, valve rod c and drain tap 123 discharge, thus brake application by spring.When partial brake, drain tap e closes after exhaust, and A chamber, C chamber air pressure balance rising differential type relay valve are in balance position.But when braking completely, admission port d continues to open.When main brake and brake application by spring action simultaneously, and when service brake exhaust and spring brake cylinder action, pressurized air enters B chamber through 124-I mouthful, act on piston b, because C chamber is emptying, piston b moves down, and closes drain tap e open air intake valve d simultaneously by valve rod c, arrive 122 mouthfuls from the pressurized airs of 121 mouthfuls through C chamber, and enter spring brake chamber.The degree that brake application by spring rises by driving brake-pressure is removed, thus avoids the overlap action of two kinds of brakings.122 mouth pressures rise, and during higher than B cavity pressure, C cavity pressure promotes piston b and rises, and air intake valve d closes, and differential type relay valve is in state of equilibrium.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
