Description

Technical Field

[0001] This invention relates to the field of saddle technology, and more particularly to a centralized lubrication maintenance-free saddle for tractor vehicles. Background Technology

[0002] The saddle is a key component of the tractor unit used to support the semi-trailer. When the vehicle turns, the semi-trailer rotates around the drawbar, and the saddle surface rubs against the semi-trailer. When the saddle surface wears down to a certain extent, it must be replaced, which is costly. The saddle also requires regular lubrication of the right support pin, the hook pin, and the left support pin. The driver must operate from the right side of the vehicle, the upper part of the chassis, and the left side of the vehicle, respectively. Especially when operating from the left side of the vehicle, there is a risk of injury if other vehicles are passing by. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a centralized lubrication, maintenance-free saddle for tractors.

[0004] This invention is achieved using the following technical solution:

[0005] A centralized lubrication maintenance-free saddle for a tractor includes a saddle body; the upper part of the saddle body is detachably provided with an mounting plate, and the lower part of the saddle body is provided with an integrated oil passage. The oil inlet of the integrated oil passage is located on one side of the saddle body, and the oil inlet of the integrated oil passage is connected to the left support pin, the right support pin and the towing hook pin of the saddle body respectively.

[0006] As a further illustration of the invention, the mounting plate is provided with countersunk holes and is connected to the upper part of the saddle body by bolts.

[0007] As a further explanation of the invention, the mounting plate is made of a wear-resistant material.

[0008] As a further explanation of the invention, the integrated oil passage includes a left support oil passage, a right support oil passage, and a locking hook oil passage;

[0009] The left support oil passage, right support oil passage, and locking hook oil passage are arranged in parallel. The oil outlet of the left support oil passage is connected to the oil inlet of the left support of the saddle body through a hose. The oil outlet of the right support oil passage is connected to the oil inlet of the right support of the saddle body through a hose. The oil outlet of the locking hook oil passage is connected to the traction locking hook of the saddle body through a hose.

[0010] As a further explanation of the invention, the oil inlet of the integrated oil passage is provided with a grease nipple and a lubrication switching switch.

[0011] As a further illustration of the invention, the lubrication switching switch includes a drainage groove and a plug; the plug slides within the groove of the drainage groove, and the grease nipple is disposed at the opening at one end of the drainage groove.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention reduces maintenance costs by providing a detachable mounting plate on the saddle, which can be removed when worn, eliminating the need to replace the entire saddle assembly. Furthermore, by incorporating an integrated oil passage at the bottom of the saddle, grease can be injected into the right side of the saddle to lubricate the left support pin, right support pin, and traction hook pin, thus improving convenience and safety.

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise explicitly specified and limited, the embodiments and features described in the embodiments of this application can be combined with each other. In the description of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0022] like Figure 1-4As shown, a centralized lubrication maintenance-free saddle for a tractor includes a saddle body 2; a mounting plate 1 is detachably provided on the upper part of the saddle body 2, and an integrated oil passage 3 is provided on the lower part of the saddle body 2. The oil inlet of the integrated oil passage 3 is located on one side of the saddle body 2, and the oil inlet of the integrated oil passage 3 is connected to the left support pin 221, the right support pin 211 and the towing hook pin 231 of the saddle body 2 respectively.

[0023] Mounting plate 1 has countersunk holes and is connected to the upper part of saddle body 2 by bolts; preferably, the upper surface of mounting plate 1 is slightly higher than the upper surface of saddle body 2; the lower part of saddle body 2 is connected to frame 7, and the upper part of saddle body 2 is in contact with trailer through mounting plate 1. When mounting plate 1 is worn, only mounting plate 1 needs to be removed, without replacing the saddle assembly, thus reducing user maintenance costs.

[0024] Mounting plate 1 is made of wear-resistant material; as long as the contact surface between mounting plate 1 and the trailer is made of wear-resistant material, there is no need to apply additional grease during use.

[0025] The integrated oil passage 3 includes a left support oil passage 33, a right support oil passage 31, and a locking hook oil passage 32; preferably, the integrated oil passage 3 is cast in one piece; the left support oil passage 33, the right support oil passage 31, and the locking hook oil passage 32 are arranged in parallel, the oil outlet of the left support oil passage 33 is connected to the oil inlet of the left support of the saddle body 2 through a hose, the oil outlet of the right support oil passage 31 is connected to the oil inlet of the right support of the saddle body 2 through a hose, and the oil outlet of the locking hook oil passage 32 is connected to the traction locking hook 23 of the saddle body 2 through a hose, thereby achieving lubrication of the left support pin 221, the right support pin 211, and the traction hook pin 231 of the saddle body 2.

[0026] The integrated oil passage 3 is equipped with a grease nipple 4 and a lubrication switching switch 5 at the oil inlet. When adding grease, all lubrication points of the saddle can be filled through only one filling port, namely the grease nipple 4. This centralized lubrication method improves the convenience and safety of adding grease.

[0027] The lubrication switching switch 5 includes a flow channel 51 and a plug 52; the plug 52 slides in the groove of the flow channel 51, and the grease nipple 4 is set at the opening of one end of the flow channel 51; by switching the plug 52 of the lubrication switching switch 5 at the flow channel 51, the lubrication of the left support pin 221, the right support pin 211 and the traction hook pin 231 can be realized.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalent elements of the claims are intended to be included within the present invention.
