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 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 balls Slot 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 a mounting tube 5, the two ends of the device tube 2 are movably sleeved with the mounting tube 5, and the two ends of the device tube 2 are connected to the retaining tube 5. The sides of the frame body 1 are provided with anti-skid lines 6, which are used to drive the device tube 2 to rotate to a certain extent when the retainer body 1 rotates. The two cage bodies 1 are made to rotate synchronously. When the cage bodies 1 stop rotating, the two cage bodies 1 can be independently rotated and disassembled. The oil device 9 is installed on the installation pipe 5, and is used ...

Embodiment 2

[0036] see Figure 1-Figure 3 Embodiment 2 is described. This embodiment further describes 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, the steel balls 4 are rollingly connected in the plurality of steel ball grooves 3, the side surface of the cage body 1 is fixedly connected with the installation pipe 5, the two ends of the installation pipe 2 are movably sleeved with the installation pipe 5, and the two sides of the installation pipe 2 are fixedly connected. The end and the side of the cage body 1 are provided with anti-skid lines 6, which are used to drive the device tube 2 to rotate to a certain extent when the cage body 1 is rotated. 1 When rotating, 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 ...

Embodiment 3

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

[0042] see Figure 5-Figure 10 , the oil delivery device 9 in the figure includes a first through hole 3...

Abstract

The invention discloses a combined cage for new energy vehicles, comprising a cage body, a device pipe, a connecting device, an oil storage device and an oil delivery device, the side of the cage body is fixedly connected with an installation pipe, and the side of the device pipe The two ends are movably socketed with the installation pipe, and the connection device is used to make the two cage bodies rotate synchronously when the cage body rotates. When the cage body stops rotating, the two cage bodies can be rotated and disassembled independently. The device is used to store lubricating oil, and the oil delivery device is used to deliver the lubricating oil in the oil storage device to the steel ball groove when the connecting device is in operation. Oil function, this combined cage for new energy vehicles solves the problem that the existing combined cages for new energy vehicles are not easy to install and disassemble when used, and is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle cages, in particular to a combined cage for new energy vehicles. Background technique [0002] Bearings, as an indispensable part of mechanical equipment, play a very important role in the normal operation of mechanical equipment. Cage, that is, bearing cage, also known as bearing retainer, 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, and there is a large sliding friction between the cage and the rolling elements, and generates a lot of heat, force and vibration. The combined effect of heat can lead to cage failure, and in severe cases, cage burns and fractures. [0003] In order ...
