Problems solved by technology

[0003] In order for the rolling elements to roll between the outer flange and the inner flange on the hub unit, it is usually necessary to install the rolling elements on the cage first and then on the inner flange. However, due to the different weights of different vehicles, for When the rolling elements and the cage can carry heavy vehicles, it is necessary to splice the two cages together and then install them on the inner flange of the hub unit, but the two cages are independent and cannot be synchronized Movement, so it is easy to cause serious wear of one of the cages and its internal rolling elements during long-term use
[0004] The existing cage structure is relatively simple and has a single function. It is difficult to realize the function of quickly combining and disassembling the two cages automatically. The cage needs to be clamped or screwed before installation. The replacement is not convenient enough and the work efficiency is reduced.

Embodiment 1

[0030] see Figure 1-Figure 3 , the combined cage for new energy vehicles in the illustration includes a cage body 1, a device pipe 2, a connecting device 7, an oil storage device 8 and an oil delivery device 9, and a plurality of steel balls are opened on the cage body 1 Groove 3, a plurality of steel ball grooves 3 are rollingly connected with steel balls 4, the side of the cage body 1 is fixedly connected with the installation pipe 5, the two ends of the installation pipe 2 are movably socketed with the installation pipe 5, and the two ends of the installation pipe 2 and the retaining The sides of the frame body 1 are provided with anti-slip lines 6, which are used to drive the device tube 2 to rotate to a certain extent when the cage body 1 rotates. The two cage bodies 1 are rotated synchronously. When the cage body 1 stops rotating, the two cage bodies 1 can be rotated and disassembled independently. The oil storage device 8 is installed in the device tube 2 for storing l...

Embodiment 2

[0036] see Figure 1-Figure 3 Describe embodiment 2. This embodiment will further explain embodiment 1. The figure includes a cage body 1, a device pipe 2, a connecting device 7, an oil storage device 8, and an oil delivery device 9. The cage body 1 is provided with A plurality of steel ball grooves 3, steel balls 4 are rollingly connected in the plurality of steel ball grooves 3, the side of the cage body 1 is fixedly connected with the installation pipe 5, the two ends of the installation pipe 2 are movably socketed with the installation pipe 5, and the two ends of the installation pipe 2 Both the end and the side of the cage body 1 are provided with anti-slip lines 6, which are used to drive the device tube 2 to rotate to a certain extent when the cage body 1 rotates. The connecting device 7 is installed in the device tube 2 for the When 1 rotates, the two cage bodies 1 rotate synchronously. When the cage body 1 stops rotating, the two cage bodies 1 can be rotated and disas...

Embodiment 3

[0041] see Figure 5-Figure 7 and Figure 9-Figure 10 Embodiment 3 is described. This embodiment will further illustrate Embodiment 1. The oil storage device 8 in the illustration includes a push block 26, an oil storage tank 27 is opened on the side of the first connecting pipe 11, and an oil storage tank 27 is opened in the first connecting pipe 11. The third chute 28 that communicates with the oil storage tank 27, the push block 26 is slidably connected with the third chute 28, and one end of the push block 26 is fixedly connected with the second extension spring 29 that is fixedly connected with the third chute 28, and the push block The bottom surface of 26 is fixedly connected with the second block 39 which is slidably connected with the third chute 28 , and the first connecting pipe 11 is provided with an oil filling member 30 for adding oil to the oil storage tank 27 .

Abstract

The invention discloses a combined retainer for a new energy automobile. The combined retainer comprises retainer bodies, a device pipe, a connecting device, an oil storage device and an oil conveying device, the side faces of the retainer bodies are fixedly connected with mounting pipes, and the two ends of the device pipe are movably connected with the mounting pipes in a sleeving mode; and the connecting device is used for enabling the two retainer bodies to synchronously rotate when the retainer bodies rotate, the two retainer bodies can independently rotate and be disassembled and assembled when the retainer bodies stop rotating, and the oil storage device is used for storing lubricating oil. The oil conveying device is used for conveying the lubricating oil in the oil storage device into a steel ball groove when the connecting device operates. When the retainer bodies stop rotating, the oil conveying function is stopped, the combined retainer for the new energy automobile solves the problem that an existing combined retainer for a new energy automobile is not easy and convenient to mount and dismount when used, and people can use the combined retainer conveniently.

Description

technical field [0001] The invention relates to the technical field of cages for new energy vehicles, in particular to a combined cage for new energy vehicles. Background technique [0002] As an indispensable part in mechanical equipment, bearings play a very important role in the normal operation of mechanical equipment. Cage, that is, bearing cage, also known as bearing cage, refers to a bearing part that partially wraps all or part of the rolling body and moves with it, to isolate the rolling body, usually guide the rolling body and keep it in the bearing , when the rolling bearing is working, especially when the load is complex and rotates at high speed, the cage has to bear a lot of centrifugal force, shock and vibration, there is a large sliding friction between the cage and the rolling elements, and a lot of heat, force and The result of the combined effect of heat will cause the cage to fail, and in severe cases, the cage will be burned and broken. [0003] In ord...
