Description
Technical Field
The utility model belongs to the vehicle safety field that traveles, in particular to axletree wheel end overheat protection system.
Background
The axle in the prior art is divided into a drum type structure and a disc type structure, and heat generated in the braking process completely depends on air cooling. Due to the fact that conventional air cooling and heat dissipation are too slow, when the working condition that continuous braking is often needed is met, thermal attenuation occurs to the axle wheels, the vehicle can be subjected to the phenomenon of brake failure, and when the working condition is met, the vehicle is usually additionally provided with a water spraying system, as shown in fig. 1, water is continuously sprayed to the brake drum/disc to reduce the temperature in the braking process, and therefore thermal attenuation of the brake drum/disc is reduced. However, the following problems still exist when the water spraying system is adopted for water spraying cooling:
1. the cooling efficiency is relatively low, and the heat generated by the axle in the braking process is difficult to dissipate in time, so that the braking performance is reduced;
2. the water spraying device needs to add water into the water tank frequently, so that the use is very inconvenient, and the defects of less goods and more oil consumption are inevitably caused by the weight of the water tank and the water;
3. the water spraying system can cause the road surface to be frozen in a cold environment, and serious potential safety hazards are caused to other passing vehicles.

The temperature sensor can detect the temperature of the wheel end of the axle and transmit the temperature information to the control box in the form of an electric signal.
Furthermore, the system also comprises an air supply pipeline and a sequence valve, wherein the air supply pipeline is connected with the air cylinder through the sequence valve.
Furthermore, a power supply is connected to the control box.
Furthermore, an overheating alarm indicator lamp is connected to the temperature sensor. Because the long downhill working condition is considered, the cooling system can not work effectively in order to avoid the situation that the supply of the vehicle air source is not sufficient, the temperature detection display and the overheating alarm are added to remind a driver to stop in time so as to prevent danger. The alarm temperature setting value is greater than the opening temperature of the electromagnetic directional valve in the control box.
Further, the system also comprises a repeater and a display screen, wherein the display screen is connected with the temperature sensor through the repeater, and the repeater is connected with the control box. In the working process of the system, the signal of the temperature sensor is amplified by the repeater and is wirelessly transmitted to a display screen of a cab, so that a driver can conveniently master the temperature of the axle end of the wheel at any time.
Further, the axle wheel end comprises a brake drum and a brake disc.
Furthermore, an electromagnetic directional valve is arranged in the control box, one end of the electromagnetic directional valve is connected with the air storage cylinder, and the other end of the electromagnetic directional valve is connected with the vortex tube.
Further, the system works on the principle that compressed air carried by the vehicle is stored in an air storage cylinder through a sequence valve, and the air pressure is maintained at 500 Kpa-700 Kpa. The control box can automatically open or cut off the compressed air from the air storage cylinder to the vortex tube through a built-in electromagnetic directional valve according to a feedback signal of a temperature sensor arranged at the wheel end of the axle. When the wheel end of the axle is higher than the set temperature, compressed air flows into the vortex tube to form high-temperature gas on the outer layer, and the high-temperature gas is directly discharged to the atmosphere from the pore plate at the edge of one end of the vortex tube; and low-temperature air flow is obtained in the central layer and reaches the nozzle through the pipeline, the low-temperature air flow from the nozzle directly acts on the rotating brake drum/disc, and the brake drum/disc is directly cooled rapidly and uniformly by utilizing the heat conduction and convection principles. When the temperature reaches a safe value, the temperature sensor transmits a signal back to the control box again, compressed air communicated to the vortex tube from the air storage cylinder is automatically cut off, and the system stops cooling. It should be noted that, in the present application, it is the prior art to detect a temperature signal through a temperature sensor and feed the temperature signal back to a control box to realize the switching of the electromagnetic directional valve.
Further, the vortex tube in the application is the prior art, and the working principle of the vortex tube is that when the wheel end of the axle is higher than a set temperature, compressed air flows into the vortex tube to be rapidly expanded and accelerated to the speed of sound, and the compressed air is injected into a vortex chamber of the vortex tube from the tangential direction to form a high-speed free vortex. The greater the rotational angular velocity of the free vortex is near the center, the different angular velocities create friction between the layers of the free vortex. The airflow angular velocity of the central part is maximum, the inner layer drives the outer layer to rotate and spirally advance, so that the energy of the airflow of the central layer is transferred to the airflow with lower angular velocity of the outer layer, the temperature of the airflow of the outer layer is continuously increased, and the airflow is directly discharged to the atmosphere from the pore plate at the edge of one end of the vortex tube; the air flow of the central layer does work on the air flow of the outer layer, so that the energy is gradually reduced, the speed is reduced, the temperature is reduced, the air flow is led out from the other end through the orifice plate at the center of the vortex tube to obtain low-temperature air flow, the low-temperature air flow reaches the nozzle through the air pipe and directly acts on the rotating brake drum/disc, and the brake drum/disc is directly cooled rapidly and uniformly by utilizing the heat conduction and convection principles.
