Description

Technical Field

[0001] The utility model relates to a brake auxiliary device, in particular to a brake cooling device suitable for a semitrailer. Background Art

[0002] When a semi-trailer or a large truck is driving heavily in an area with extremely undulating terrain, it is necessary to go through a continuous large downhill or large uphill. When driving on a large uphill, it is only necessary to continuously add oil to ensure the vehicle's driving. When driving on a continuous large downhill, in order to control the speed and prevent the danger of speeding, it is necessary to continuously brake the vehicle to control the speed. Continuous braking will cause the brake components to overheat, which will in turn cause the vehicle's brakes to fail, causing the danger of excessive speed, seriously affecting driving safety. The current main method is to stop at each service area and spray water on the wheels to cool them down, so as to ensure the reliable operation of the brake device. However, this method is time-consuming and labor-intensive and will seriously affect the efficiency of vehicle transportation. Another part of truck drivers specially install water tanks on the vehicles to continuously spray water on the brakes to cool them down, but this method cannot accurately control the brake temperature, and the driver can only roughly estimate that continuous spraying will cause the water in the water tank to run out quickly, and intermittent spraying cannot accurately understand the brake temperature state. Water is sprayed when it should not be sprayed, and water is not sprayed when it is needed, affecting the brake temperature control.

[0003] At present, the utility model with patent number CN207984832U discloses a semi-trailer brake cooling water sprayer, including a mounting seat, the bottom end of which is respectively fixed with a baffle, a partition and a connecting column, a buffer plate and a clamp are respectively arranged between the baffle and the partition, a push rod is fixed in the middle of the side of the clamp away from the buffer plate, one end of the push rod penetrates the partition and is fixed with a moving block, a double-axis motor is installed at the bottom end of the connecting column, one end of the output shaft of the double-axis motor is fixed with a driving gear, both sides of the double-axis motor are provided with a driven gear, the middle part of the side of the driven gear close to the partition is fixed with a horizontally placed threaded rod, one end of the threaded rod penetrates the moving block and extends to the inside of the partition, and a plurality of fixed blocks are equidistantly fixed on the side of the baffle close to the buffer plate. The utility model is novel in design, ingenious in structure, simple in operation, convenient for operators to install or disassemble the water sprayer, and at the same time conducive to extending the service life of the water sprayer. However, this patent is mainly used for fixing the sprinkler, which can neither store water nor monitor the brake temperature, and is even more incapable of spraying water to cool down the brakes that are too hot. It must be used in conjunction with the sprinkler, which is not convenient to use. Summary of the invention

DETAILED DESCRIPTION

[0020] The brake cooling device applicable to a semi-trailer according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0021] In the specific implementation mode 1 of the present application, Figures 1 to 4As shown, the brake cooling device for a semitrailer is suitable for a trailer, a trailer cargo box 1 is fixedly installed on the upper part of the beam 4, wheels 3 are installed at the rear positions of the lower two sides of the beam 4 by hanging, tool boxes 2 are fixedly installed on both sides of the middle section of the beam 4, and a brake cooling water tank 5 is fixedly installed in the middle of the beam 4 by a bracket, so that the space of the beam 4 is fully utilized to store as much cooling water as possible for cooling, each wheel 3 is equipped with a water spray cooling mechanism 6, and each wheel 3 is equipped with a separate water spray cooling mechanism 6, so that each system is independent of each other, and the current temperature of a single wheel can be effectively understood, so that the driver can timely understand the actual working condition of the vehicle, and the water spray cooling mechanism 6 is installed on the beam 4, and the water spray cooling mechanism 6 also includes a dustproof shell 6-1, a mounting foot 6-2, telescopic rod 6-3, dustproof plate 6-4, water nozzle 6-5 and temperature sensor 6-6. The dustproof plate 6-4 is installed at the lower part of the dustproof shell 6-1 to form a closed box body. The mounting feet 6-2 are fixedly installed on both sides of the box body. The dustproof plate 6-4 built into the dustproof shell 6-1 is controlled to open and close through the telescopic rod 6-3. The water nozzle 6-5 and the temperature sensor 6-6 are fixedly installed on the inner side of the dustproof plate 6-4. The water nozzle 6-5 is aimed at the brake in the wheel hub of the wheel 3; the temperature sensor 6-6 is connected to the display in the vehicle cab through a line; the brake cooling water tank 5 is connected to the manual valve in the cab through a pipeline, and the manual valve in the cab is connected to the water nozzle 6-5 of the water spray cooling mechanism 6; the brake cooling water tank 5 has a built-in water pump. The temperature sensor 6-6 reports the brake temperature of each wheel 3 to the driver, who then decides whether to open the valve to spray water to cool the brake through the water nozzle 6-5. The dustproof plate 6-4 controlled by the telescopic rod 6-3 can store the water nozzle 6-5 and the temperature sensor 6-6 in the dustproof housing 6-1 on non-downhill sections to prevent the temperature sensor 6-6 from being damaged.

[0022] The utility model number is CN207984832U, which is a semi-trailer brake cooling water sprayer (hereinafter referred to as "the patent"). The patent is mainly used for fixed sprayers, which can neither store water nor monitor the brake temperature, and cannot spray water to cool the brake with excessive temperature. It must be used with a sprayer, which is not convenient to use. The patent uses a foldable water spray cooling mechanism 6 and its internal water nozzle 6-5 and temperature sensor 6-6 to sense the temperature of the brake in real time and prompt the driver. The driver then decides when to spray water to cool it down, making it more convenient to use and effectively ensuring that the brake is always in a normal state.

[0023] The second embodiment is based on the first embodiment, and the other structures are the same, the only difference is that Figure 5 As shown, the dustproof shell 6-1 is connected to the surface of the beam 4 through the retractable support 6-7, and the overall height of the water spray cooling mechanism 6 can be adjusted through the retractable support 6-7, so that it can adapt to various types of trailers and expand its application range.

[0024] In order to further optimize the working efficiency of the present application, in order to further improve the working range of the water spray nozzle 6-5 and the temperature sensor 6-6, and thus adapt to more vehicle models, the water spray nozzle 6-5 and the temperature sensor 6-6 are respectively installed on the inner side of the dustproof plate 6-4 through a rotatable turntable. In order to improve the water spray range, the nozzle of the water spray nozzle 6-5 is a duckbill nozzle, which not only ensures the flow rate but also the coverage range. In order to enable the equipment to automatically control the temperature of the wheel 3, the brake cooling water tank 5 is connected to the water spray nozzle 6-5 through a pipeline, and the water spray nozzle 6-5 has a built-in solenoid valve. The control machine in the cab is connected to the built-in solenoid valve of the water spray nozzle 6-5 and the temperature sensor 6-6 through wires. When the temperature sensor 6-6 senses that the temperature of the wheel 3 is too high, the control machine can control the built-in solenoid valve of the water spray nozzle 6-5 to open, and spray water to cool the brake. In order to allow the driver to further observe the status of the brake, the temperature sensor 6-6 is integrated with a camera. In order to allow the driver to better understand the cooling water inventory, the brake cooling water tank 5 has a built-in liquid level sensor.

[0025] When in use, install the brake cooling device suitable for the semi-trailer and connect the corresponding pipelines, and the equipment can be put into use.

[0026] When the utility model is in use, the specific operations are as follows:

[0027] When the vehicle enters a continuous downhill section by manual control, the driver controls the telescopic rod 6-3 through the controller to open the dust shield 6-4, so that the dust shield 6-4 is fixed at a pre-selected angle, so that the water nozzle 6-5 and the temperature sensor 6-6 can be aimed at the brake of the wheel 3, especially the water nozzle 6-5 can spray water to the side and inside of the brake, the temperature sensor 6-6 senses the temperature in real time, and transmits the data back to the display in the cab, and automatically alarms when the temperature is too high, and then the driver opens the valve, and the water in the brake cooling water tank 5 passes through the valve under the action of the water pump and is sprayed onto the brake surface through the water nozzle 6-5, so as to achieve rapid cooling.

[0028] In automatic control, all working steps are the same. When the temperature sensor 6-6 senses that the brake temperature of the wheel 3 is too high, the controller controls the built-in solenoid valve of the water spray nozzle 6-5 to open and spray water to cool the brake.

[0029] In summary, the brake cooling device suitable for a semi-trailer in the embodiment of the utility model senses the brake temperature through the temperature sensor 6-6, and when the brake temperature is too high, the driver controls the water nozzle 6-5 to spray water on the brake, which can effectively improve the driver's control over the brake temperature and effectively ensure driving safety.
