Description
Technical field
Improved the present invention relates to light truck and the design of microcaloire brake fluid system vacuum booster unit, directly affect vehicle brakes performance, specially a kind of novel hydraulic brakes.
Background technology
Many lorries all mitigate the power that driver is used to brake using energy assisted braking system, and booster has two kinds of conventional patterns, and one kind is vacuum booster, and another is hydraulic booster.
It is most extensive that vacuum booster is applied, and vacuum booster needs the air under vacuum and atmospheric pressure when working.Booster will correctly work, it is necessary to have enough vacuum and air to import.Most of boosters, which import air, identical method, imports the vacuum that vacuum can be supplied by engine suction manifold or backing vacuum pump is produced and provides.Backing vacuum pump is the pump driven by transmission belt, cam or motor.
The vacuum of engine suction manifold supply, typically all one vacuum hose is directly connected on vacuum booster from inlet manifold, and one vacuum valve of band is used for preventing booster from losing vacuum on flexible pipe.The problem of this system is that the increase and decrease of manifold vacuum becomes with engine acceleration or deceleration, such as under two kinds of the long gentle slope operating mode under traffic jam or vehicle, clutch and brake pedal can continuously be stepped on, vacuum in its system is the process of a dynamic change, it can cause brake booster vacuum not enough, the power-assisted of generation is small, can not meet the requirement continuously braked, final feed back on brake is that brake force is inadequate, and vehicle braking is weak.It is many to also use vacuum can system as the vehicle in booster power-assisted source with manifold vacuum in the recent period, but be due to seal bad, easy gas leakage；Or the flexible pipe of connection is most easily inhaled flat, influences booster performance.
The content of the invention
The present invention under long two kinds of operating modes in gentle slope, can continuously step on clutch and brake pedal for commercial car under traffic jam or vehicle, meet the requirement continuously braked, specially a kind of novel hydraulic brakes.
The technical scheme is that, a kind of novel hydraulic brakes, including engine, engine is set after vehicle frame water tank, and engine is provided with engine suction manifold vacuum port, it is characterised in that：A vacuum tank 5 is provided with crossbeam before vehicle frame water tank, engine suction manifold vacuum port 1 is connected by vacuum nylon tube 1 and vacuum tank 5, vacuum tank 5 is connected by vacuum nylon tube 28 and the total pump assembly 9 of vacuum booster band again, and the vacuum booster vacuum inlet 10 of the wherein total pump assembly 9 of vacuum booster band is the connector with vacuum nylon tube 28.
Further improve is：The vacuum nylon tube 1 that engine suction manifold vacuum port 1 and vacuum tank 5 are connected is provided with check valve 3.
Further improve is：Vacuum nylon tube 1 and the nylon tube that vacuum nylon tube 28 is φ 10mm, two nylon tube two are all 12mm mouthfuls of then lineds of reducing φ, are directly sleeved on engine suction manifold mouthful 1 and vacuum booster air inlet 10.
Further improve is：Vacuum horn 6 and discharging valve 7 are additionally provided with vacuum tank 5.
Further improve is：The joint of vacuum nylon tube 1 and vacuum nylon tube 28 on vacuum tank 5 is quick connector 4.
Further improve is：The volume of described vacuum tank 5 is 12L.
Beneficial effect：
Hydraulic system uses vacuum booster unit in the present invention, according to the fully loaded of vehicle（Overload）Gross mass design uses the model of vacuum booster, the efficiency vacuumized further according to engine and vacuum booster discharge capacity and road conditions, and whether design increases vacuum tank.It must increase vacuum tank more than more than 3.5T in gross mass, increase vacuum tank typically at the crossbeam before vehicle frame water tank, this vacuum tank size is generally 12L（With reference to the displacement volume of oil pressure x boosters）, meet continuous 6 foot brake performance requirement after vacuum failure.
Have four interfaces on vacuum tank, one is entered vacuum port, one goes out vacuum port, one connect display vacuum higher limit alarm mouthful, the exhaust outlet of a draining and impurity.By many experiments, inlet and outlet all uses quick connector, and the flexible pipe of connection engine suction manifold mouthful and vacuum tank uses the nylon tubes of φ 10, and centre connects check valve；The flexible pipe for connecting vacuum tank and vacuum booster uses the nylon tubes of φ 10, this two nylon tube two are all 12 mouthfuls of then lineds of reducing φ, it is directly sleeved on engine suction manifold mouthful and booster air inlet, big suction nylon tube will not also be inhaled flat again, hardly deform, quick connector good airproof performance, it is ensured that the high vacuum of vacuum tank.Alarm and the connection of instrument board indicator lamp, show the higher limit of vacuum, can play warning on vacuum tank；Exhaust outlet periodically discharges water droplet and impurity in vacuum tank, and the face of keeping away is brought into booster, it is ensured that the service life of rubber diaphragm and spring in booster.High vacuum is the important parameter that vacuum booster performance embodies, and directly affects vehicle brakes.
Beneficial effect：
The invention of such a vacuum tank and annex, the vacuum that vacuum tank is stored in system can be ensured, upper and lower fluctuation with vacuum level in inlet manifold is unrelated, and it is not easy gas leakage, good seal performance, the flexible pipe of connection is not easy to deformation, ensure that the vacuum in vacuum tank reaches -70.5KP at any time, the oil pressure of brakes typically can reach 11MP or so, and meet the efficiency continuously braked during heavily loaded descending, and braking ability is good.
