DETAILED DESCRIPTION

[0019] The utility model provides a centralized lubrication system for a semi-trailer. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0020] See also Figure 1-Figure 4The utility model provides a centralized lubrication system for a semi-trailer, comprising an oil supply mechanism, a main oil pipe 1, a distributor assembly 2 and a plurality of sub-oil pipes 3, the main oil pipe 1 is connected to the input end of the distributor assembly 2, the plurality of sub-oil pipes 3 are connected to the output end of the distributor assembly 2, the output end of each sub-oil pipe 3 is connected with a grease nipple and faces each lubrication point, the input end of the main oil pipe 1 is connected with a quick connector 41, the quick connector 41 is arranged at the outer side of the frame beam through a connector bracket 42, and the oil supply mechanism is used to connect with the quick connector 41 for oil supply.

[0021] The centralized lubrication system provides pressurized lubricating oil through the oil supply mechanism, which is transported to the distributor assembly 2 through the main oil pipe 1, and then accurately controlled and distributed to each sub-oil pipe 3 by the distributor assembly 2. Finally, the lubricating oil is applied to each lubrication point of the semi-trailer's load-bearing mechanism by the grease nipple. The whole process realizes centralized, automated and efficient lubrication of many lubrication points.

[0022] Compared with the traditional manual oiling method, the centralized lubrication system provided by the utility model can lubricate all lubrication points of the semi-trailer load-bearing mechanism synchronously or sequentially at one time, greatly reducing the time and physical effort of manual operation and significantly improving the efficiency of lubrication operations. In addition, the setting of the quick connector 41 makes the connection and disassembly of the oil supply mechanism and the centralized lubrication system simple and quick.

[0023] When the grease fitting is opened, the oil pressure of the sub-oil pipe 3 needs to reach a certain threshold value to overcome the resistance of the one-way valve body inside the grease fitting so that the lubricating oil can be smoothly ejected from the grease fitting. Similarly, the quick connector 41 is also provided with a one-way valve body, which prevents the lubricating oil in the main oil pipe 1 from overflowing in reverse flow.

[0024] In this embodiment, the quick connector 41 is tilted downward, which has the following advantages: 1. It is conducive to the oil supply mechanism to transport lubricating oil, and the lubricating oil enters the distributor assembly 2 more quickly through the main oil pipe 1; 2. By utilizing the effect of gravity, the lubricating oil remaining in the connector or at the interface is easier to flow downward, effectively reducing the possibility of lubricating oil dripping or accumulating outside the connector, thereby avoiding the lubricating oil dripping onto the ground to cause environmental pollution, or contaminating other parts of the vehicle body to affect the appearance and performance; 3. For the operator, the downward-tilted quick connector 41 has a clearer line of sight when docking the oil supply equipment, and the docking action is more natural and smooth, without the need to look up or down excessively, which reduces the difficulty of operation, improves work efficiency, and also reduces safety hazards caused by improper operation.

[0025] The quick connector 41 is installed on the connector bracket 42 through a threaded connector 43 and a gasket 44. The connector bracket 42 is an L-shaped iron block and is welded and fixed to the outer side of the frame beam. The end of the threaded connector 43 away from the quick connector 41 is connected with a plug connector 45. The input end of the main oil pipe 1 is connected to the plug connector 45. The threaded connector 43 is used in conjunction with the gasket 44 to ensure that the quick connector 41 is firmly fixed on the connector bracket 42, while providing reliable sealing performance to prevent lubricating oil from leaking from the connector connection under high pressure. This connection method has a simple structure, high connection strength, and is easy to adjust and maintain, thereby ensuring the stability and reliability of the quick connector 41 under long-term, high-intensity working conditions.

[0026] The joint bracket 42 of the L-shaped iron block makes full use of the outer space of the frame beam, and arranges the quick connector 41 and the auxiliary components in a limited space in a compact and orderly manner, avoiding interference with other important components. The joint bracket 42 is fixed to the outer position of the frame beam by welding, and has a solid structure and strong impact resistance. It can withstand various vibrations and impact forces generated by the semi-trailer during driving, ensuring the long-term stable operation of the quick connector 41 and its connecting parts.

[0027] Preferably, the input end of the quick connector 41 is provided with a protective cover 46, one end of which is a collar structure, which is sleeved on the gasket 44 to prevent loss. When the quick connector 41 is not in operation, the protective cover 46 effectively shields the input end of the quick connector 41, which can prevent dust, impurities, moisture and other external foreign matter from entering the quick connector 41, and prevent these foreign matter from entering the lubricating oil circuit during system operation, causing blockage, wear or other failures, thereby ensuring the normal operation of the lubrication system and extending the service life of the system.

[0028] Specifically, the oil supply mechanism includes an oil tank and an oil pump. During lubrication operation, the oil pump is connected to the quick connector 41 through an oil pipe. The oil pump controls the oil delivery through timers, flow control elements, valves and other components to ensure that each lubrication point is lubricated according to the specified amount.

[0029] In this embodiment, the distributor assembly 2 includes a distributor bracket 21, two six-hole distributors 22 and a two-hole distributor 23 arranged on the distributor bracket 21, and the two six-hole distributors 22 and the two-hole distributor 23 are arranged in series. By setting two six-hole distributors 22 and a two-hole distributor 23, the lubrication path can be finely managed to achieve accurate control of different parts and different lubrication requirements in the semi-trailer load-bearing mechanism. The orifice on each distributor corresponds to a sub-oil pipe 3, which can accurately distribute the flow direction and flow rate of the lubricating oil according to the actual needs of each lubrication point to ensure that each lubrication point is properly lubricated.

[0030] In this embodiment, there are 14 lubrication points, so 14 sub-oil pipes 3 are configured, namely left front wheel hub A, left front wheel axle B, left front adjusting arm C, right front wheel hub D, right front wheel axle E, right front adjusting arm F, left balance beam pin shaft H, right balance beam pin shaft G, left rear wheel hub P, left rear wheel axle N, left rear adjusting arm M, right rear wheel hub L, right rear wheel axle K, and right rear adjusting arm J.

[0031] The distributor structure arranged in series can flexibly cope with the complex lubrication requirements of the semi-trailer load-bearing mechanism by increasing or decreasing the number of distributors, changing the type of distributors, or adjusting the connection method between distributors. For example, two six-hole distributors 22 can meet the synchronous or sequential lubrication of a large number of lubrication points, while the two-hole distributor 23 can perform refined management of specific lubrication points that require individual control or special lubrication strategies. This design enables the centralized lubrication system to adapt to semi-trailers of different models and structures, improving its versatility and scope of application.

[0032] Preferably, the diameter of the main oil pipe 1 is larger than the diameter of the sub-oil pipe 3, which is conducive to increasing the speed at which the lubricating oil enters the distributor. The main oil pipe 1 is made of a pipe material with pressure resistance and high temperature resistance, which is conducive to improving the safety during the working process. In addition, compression joints are provided at both ends of the main oil pipe 1 to facilitate the connection of the quick connector 41 and the distributor.
