Description

Technical Field

[0001] The utility model relates to a suspended expansion water tank for heavy truck models, belonging to the field of heavy trucks. Background Art

[0002] The current water cooling systems for heavy truck models are all forced water circulation systems, that is, the ability of the coolant is improved by a water pump, and the coolant is forced to circulate inside the engine. In this system, a pipeline is usually set at the water inlet of the water pump to connect to the water replenishing port of the expansion water tank. When the expansion water tank replenishes liquid, gas will accumulate inside the water cooling system, and a degassing pipeline needs to be set to discharge the gas inside the water cooling system through the expansion water tank assembly. Currently, the expansion water tanks of heavy truck models are all installed on the chassis, and there are two mainstream layout methods: one is to be arranged behind the cab, which will cause the water replenishing and degassing pipelines to be relatively long; the other is to be arranged on the cooling module, which will cause a large space occupation. Therefore, the existing two installation positions of the expansion water tank are not conducive to the overall vehicle layout and cooling performance. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will provide a detailed description of the technical solutions of the present application through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "front", "left", and "right" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the protected content of the present utility model.

[0021] As Figure 1 , Figure 2 and Figure 3 shown, a suspended expansion water tank for a heavy truck model includes a cab welding assembly 1 and a cooling module 8, and further includes an expansion water tank assembly 2. The expansion water tank assembly 2 is installed at the bottom of the cab welding assembly 1 and above the cooling module 8. The expansion water tank assembly 2 is located at the highest point of the water cooling system, which can ensure the smooth realization of the functions of the expansion water tank to supplement coolant for the water cooling system and accommodate the liquid-gas mixture overflowing due to the high temperature of the engine.

[0022] The expansion water tank assembly 2 includes an expansion water tank body 5. The bottom of the expansion water tank body 5 is respectively connected with a degassing pipeline 3 and a makeup water pipeline 7. In order to meet the height requirements of the expansion water tank assembly 2 in the whole water cooling system, it is necessary to shorten the makeup water and degassing pipelines as much as possible to ensure the makeup water and degassing efficiency, and to minimize the space occupation as much as possible to increase the size of the cooling module 8 and improve the performance of the water cooling system. The other end of the makeup water pipeline 7 is connected to the water pump inlet. An expansion water tank pressure cap 9 is installed at the upper right of the expansion water tank body 5, which is used to discharge expansion air when the system pressure is high and inhale air when cooling. An expansion water tank cap 10 is installed at the front left of the expansion water tank body 5, and the direction is inclined forward to facilitate the filling of coolant. A liquid level alarm sensor 12 is installed at the left side of the bottom of the expansion water tank body 5, which is used to detect the water level information in the water tank in real time and alarm when the water level is too low.

[0023] In some embodiments, as Figure 1 shown, the expansion water tank assembly 2 is fixed to the bottom of the cab welding assembly 1 by bolts, which is convenient for disassembly and assembly, and ensures that when the cab is flipped, the expansion water tank assembly 2 moves together with the cab welding assembly 1.

[0024] In some embodiments, as Figure 1 , Figure 2 and Figure 3 shown, the degassing pipeline 3 is connected to the bottom of the expansion water tank body 5 through a quick connector 4. Two degassing connectors 11 are provided at the bottom of the expansion water tank body 5, and the degassing connectors 11 are connected to the quick connector 4 of the degassing pipeline 3, which is convenient for disassembly and assembly.

[0025] In some embodiments, MIN and MAX scale lines are provided on the front of the expansion tank body 5, facilitating visual observation of the liquid level line and timely replenishment of the coolant.

[0026] In some embodiments, the water replenishing port 6 at the bottom of the expansion tank body 5 is connected to the water replenishing pipeline 7. When the coolant in the cooling system is less, the cooling system can be replenished with water from the expansion tank body 5 along the water replenishing pipeline 7.

[0027] In some embodiments, the heavy truck model is any one of heavy truck fuel, gas, hydrogen energy and pure electric vehicles, with a wide range of applications.

[0028] In some embodiments, the gas removal pipeline 3 is made of nylon pipe, and the water replenishing pipeline 7 is made of ethylene propylene diene monomer (EPDM) rubber pipe, with more stable use performance.

[0029] During use, the gas in the cooling system is transported to the expansion tank body 5 along the gas removal pipeline 3 and discharged through the gas outlet on the expansion tank pressure cap 9; when the cab welding assembly 1 is flipped, the expansion tank assembly 2 moves accordingly. Since the gas removal pipeline 3 and the water replenishing pipeline 7 have a certain flexibility and surplus length, the normal use of the gas removal and water replenishing functions will not be affected.

[0030] The suspension type expansion tank for heavy truck models of the present utility model applies the expansion tank to the heavy truck cooling system, solving the problems of large volume occupation of the expansion tank and long water replenishing and gas removal pipelines; avoiding interference with surrounding components, improving the reliability of the product, and greatly improving the aesthetics; installing the expansion tank above the cooling module (radiator) and fixing it at the bottom position of the cab, being less affected by the remaining chassis components, effectively reducing the types and quantities of components, and at the same time improving the consistency of the product.

[0031] In addition, those skilled in the art can understand that although some embodiments described herein include certain features contained in other embodiments rather than other features, the combination of features of different embodiments also means being within the protection scope of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
