Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of universal joint, and relates to a universal joint, in particular to a novel automatic lubrication universal joint. BACKGROUND

[0002] Universal joint is universal joint, is the machine part that realizes variable angle power transmission, is used to the position that needs to change transmission axis direction, it is the "joint" part of the universal transmission device of automobile drive system, universal joint and transmission shaft combination are called universal joint transmission device, on the vehicle of front engine rear wheel drive, universal joint transmission device is installed between transmission output shaft and drive axle main reducer input shaft, and the vehicle of front engine front wheel drive omits transmission shaft, and universal joint is installed between front axle half shaft and wheel which is responsible for driving and steering.

[0003] Because the cross connecting shaft of universal joint and transmission shaft will repeatedly rub, it is particularly important to lubricate it, and its lubrication degree directly affects its service performance and life.

[0004] At present, the main way of lubricating universal joint is to maintain it regularly by artificial, and the lubricating grease is added to the friction connection of universal joint during the maintenance process, but this way of lubricating by artificial adding lubricating grease is more troublesome, and the maintenance is not timely, which can easily cause excessive friction damage. SUMMARY

[0005] The utility model discloses a novel automatic lubrication universal joint to solve the above problems in the prior art.

[0006] The utility model discloses a novel automatic lubrication universal joint, including cross connecting seat and cross connecting column, its characterized in that, the cross connecting seat is provided with transmission shaft, the transmission shaft is connected with cross connecting seat on cross connecting column, the cross connecting column is opened in the oil storage layer, the cross connecting column is opened and is connected with the oil storage layer a plurality of oil outlet holes on the contact with cross connecting seat, a plurality of oil outlet holes all are provided with the ball on.

[0007] In the above-mentioned novel automatic lubrication universal joint, the cross connecting column is opened and is provided with the plug on the oil injection hole.

[0008] In the above-mentioned novel automatic lubrication universal joint, the cross connecting column is fixed with bolt on transmission shaft, and the transmission shaft is provided with the connecting flange.

[0009] Compared with the prior art, this utility model sets an oil reservoir, an oil outlet and a ball bearing in a cross-shaped connecting shaft. The ball bearing converts the original sliding friction into rolling friction, reducing wear. When the ball bearing rolls, it will bring out the lubricant in the oil reservoir to achieve automatic lubrication. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the main structure of this utility model.

[0011] Figure 2 This is a cross-sectional structural diagram of the present invention.

[0012] In the diagram, 1 is the cross connector; 2 is the cross connector post; 3 is the drive shaft; 4 is the oil reservoir; 5 is the oil outlet; 6 is the ball bearing; 7 is the oil injection hole; 8 is the plug; and 9 is the connecting flange. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, this novel automatic lubrication universal joint includes a cross connecting seat 1 and a cross connecting column 2. A drive shaft 3 is provided on the cross connecting seat 1, and the drive shaft 3 is movably connected to the cross connecting seat 1 by the cross connecting column 2. An oil storage layer 4 is provided inside the cross connecting column 2, and a plurality of oil outlet holes 5 connected to the oil storage layer 4 are provided on the cross connecting column 2 at the contact point with the cross connecting seat 1. Each of the plurality of oil outlet holes 5 is provided with a ball bearing 6.

[0015] To elaborate further, the cross-shaped connecting column 2 has an oil injection hole 7, and a plug 8 is installed on the oil injection hole 7.

[0016] To elaborate further, the cross-shaped connecting column 2 is bolted to the drive shaft 3, and the drive shaft 3 is equipped with a connecting flange 9. The original sliding friction is converted into rolling friction by the ball bearings 6, which reduces wear. When the ball bearings 6 roll, they will bring out the lubricant in the oil reservoir 4 to achieve automatic lubrication.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0018] Although the terms cross connecting seat 1, cross connecting column 2, transmission shaft 3, oil storage layer 4, oil outlet hole 5, ball 6, oil injection hole 7, plug 8, connecting flange 9 are used more in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; it is contrary to the spirit of the utility model to interpret them as any kind of additional limitation.
