Abstract

The invention discloses a combined retaining device for an electric vehicle, which relates to the field of new energy automobile parts, and comprises two relatively placed retainers, steel ball grooves are evenly arranged around the retainer, mounting holes are arranged around opposite sides of the retainer, and the retainer A mounting hole is opened, and a first connecting piece is connected to the opposite side of the cage. The first connecting piece includes a first base body. The first base body is a ring structure. The base body is coaxially arranged, the opposite side of the first ring body is fixedly connected to the tubular first ring sleeve, and the opposite side edge of the first ring sleeve is surrounded by a snap-in groove; the opposite side of the first ring sleeve is provided with a ring-shaped second base body. The two bases are respectively connected to the first connectors on both sides, and both sides of the second base are provided with snap-in blocks corresponding to the snap-in slots on the first ring; the snap-in slots and the snap-in blocks are correspondingly provided with fastening hole. Solving the problem of not being able to dissipate heat efficiently, the combined type keeps the device running smoothly for a long time and is easy to disassemble.

Description

technical field [0001] The invention belongs to the field of new energy automobile parts, and in particular relates to a combined holding device for electric automobiles. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] The cage, that is, the bearing cage, refers to the bearing part that partially wraps all or part of the rolling body and moves with it, to isolate the rolling body, and 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 is generated, the result of the combined force and heat will be It will cause the cage to fail, and in severe cases, it will cause the...
