Description
Technical field
The utility model relates to automobile cooling system, relates in particular to the improvement design of the circulating water path of the heat exchanger of hydrodynamic retarder.
Background technique
Brake system of car is one of most important system in vehicle safety travel.Along with the improvement of engine technology development and road conditions, the travelling speed of automobile and single range ability all have a great development, the kinetic energy that travels significantly improves, thereby make traditional friction disk type braking device more and more can not adapt to long-time, high-intensity need of work, because if frequently or for a long time use Service Brake, there will be the phenomenon that causes Braking efficiency heat fade because friction plate is overheated, when serious, can cause braking failure, even cause and blow out or the phenomenon such as tire spontaneous combustion, serious threat is to traffic safety.The road conditions that need long-time braking for mountain area etc., domestic user generally adopts installs water drenching device additional, and braking system is carried out to Physical temperature-lowering, and vehicle is also because frequently change the increase that brake shoe and tire cause cost of transportation.In addition, the enforcement of new national standard GB7258 has had higher requirement to vehicle security, and this will speed up development and the application of development and application, the especially hydrodynamic retarder of auxiliary braking.
Hydrodynamic retarder is made up of stator, rotor, adpting flange, heat exchanger and oil groove etc., and hydrodynamic retarder is to be connected with transmission shaft by adpting flange, and transmission shaft drives adpting flange to rotate while rotation, and adpting flange is connected with rotor by connecting bolt.When carrying out when slow, control system is sent instruction, control control valve is opened, gas is pumped into the medium in oil groove (machine oil) in the active chamber between stator and rotor, because rotor is connected with vehicular transmission shaft, and stator is fixed on the shell of retarder, and rotor is rotated by transmission shaft rotating band moving medium together, after high speed liquid flow impact stator, apply one and the rightabout active force of sense of rotation to rotor like this, this active force can make rotating speed of transmission shaft slowly lower; Along with rotating speed of transmission shaft declines, the speed of a motor vehicle also slows down, and then produces retarded acting.In the time removing retarded acting, control system dead electricity, control valve is closed, and the gas that acts on oil groove upper end is excluded, and like this, the liquid in active chamber can push back medium to oil groove under the effect of centrifugal force, and hydrodynamic retarder is deactivated.Due to the liquid in active chamber, to make at the volley to import and export mineralization pressure poor, and then impel medium circulation, and in the time that liquid is flowed through heat exchanger, the heat energy that automobile kinetic energy is transformed into is taken away and dispels the heat from the cooling water of engine-cooling system.For hydrodynamic retarder, as long as cooling system has enough heat dissipation potentiaies, its slow ability is unlimited.Due to hydrodynamic retarder time work different from motor, therefore under normal circumstances, can not increase the heat load of motor, therefore hydrodynamic retarder can continue lower long slope.
At this, the cooling circulating water of hydrodynamic retarder draws from car load cooling system, is undertaken by the principle of cooling retarder after first cooled engine, and hydrodynamic retarder is the kinetic transformation of vehicle is become to heat energy and taken away and dissipated by engine cooling water at work.The heat exchanger of hydrodynamic retarder self has enough powerful heat exchanging function, as long as have enough cooling water flows and cooling range, when cooling water flow is that 8L/s, import cooling water temperature enter with 80 DEG C, when outlet temperature is controlled at 105 DEG C, heat exchanging function reaches 700kW.But, owing to existing by water pump to the short circle water route between built-in thermostat in current motor, therefore, cannot all the flow through heat exchanger of hydrodynamic retarder of engine cooling water carries out heat exchange, therefore, car load heat dissipation potential is maximum just in 200kW left and right, if the heat dispersion of hydrodynamic retarder is not all right at present, water-exit temperature exceedes after limit value, and hydrodynamic retarder can fall turns round protection; In addition, in this kind of situation, while using hydrodynamic retarder, engine water temperature will significantly change, and cause sometimes engine water temperature to report to the police, and affect hydrodynamic retarder and use.As can be seen here, no matter select that hydrodynamic retarder, improve car load heat radiation, meet user's usage requirement particularly crucial.
