[0002] The function of the inner and outer ball cages of a car is to transfer the power of the engine from the transmission to the two front wheels to drive the car at high speed. The inner ball cage is connected to the differential part of the transmission, and the outer ball cage is connected to the wheel part. The function of the outer ball cage is both for power output and when the vehicle turns. The ball cage is generally composed of a bell-shaped case, a tripod bearing or steel balls, a dust cover, a clamping ring, and grease.
[0003] When a vehicle encounters a bumpy road during driving, the existing car ball cage generally performs shock absorption according to other shock absorption systems inside the vehicle. Generally, the car ball cage itself is not equipped with a shock absorption structure, so the shock absorption effect of the car ball cage is relatively limited, which may lead to the stability and service life of the internal parts of the car ball cage are usually low. Therefore, during use, it may be necessary to frequently maintain or replace the internal parts of the car ball cage. The operation process is relatively cumbersome, which increases the use cost of the car ball cage and reduces the practicality of the existing car ball cage. Utility Model Content

DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0031] See also Figure 1-4 The utility model provides a technical solution: an automobile inner ball cage, comprising a bell-shaped housing 1, a plum-shaped retaining ring 2 fixed inside the bell-shaped housing 1, a shock-absorbing structure 200 installed inside the bell-shaped housing 1 for shock-absorbing the internal parts of the bell-shaped housing 1, and a fixing component 300 installed on the right side of the bell-shaped housing 1 for fixing the bell-shaped housing 1;
[0032] By using the bell-shaped housing 1, the plum blossom retaining ring 2, the shock-absorbing structure 200 and the fixing assembly 300 in coordination, a shock-absorbing effect can be provided for the inner ball cage itself, thereby effectively improving the stability and service life of the internal parts of the inner ball cage of the automobile, thereby effectively avoiding the need for frequent maintenance or replacement of the internal parts of the inner ball cage of the automobile, reducing the use cost of the inner ball cage of the automobile, making it more convenient to use and improving the practicality of the inner ball cage of the automobile.
[0033] In this embodiment, the shock absorbing structure 200 is a structure that enables the inner ball cage of the automobile to have a shock absorbing effect.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the shock absorbing structure 200 includes a shock absorbing assembly 201 installed inside the bell-shaped housing 1 , a tripod bearing 202 slidably connected inside the bell-shaped housing 1 , and an internal spline 203 opened inside the tripod bearing 202 .
[0035] It should be noted that the shape of the tripod bearing 202 is adapted to the bell housing 1 , ensuring that the tripod bearing 202 can stably and effectively slide in the bell housing 1 .
[0036] In this embodiment, the shock absorbing assembly 201 is a structure for absorbing shocks of the internal parts of the bell housing 1 .
[0037] like Figure 1 and Figure 2 As shown, the shock absorbing assembly 201 includes a damper 2011 fixed to the right side wall of the bell-shaped housing 1, a shock absorbing spring 2012 fixed to the right side wall of the bell-shaped housing 1, and a fixed cylinder 2013 fixed to the left side of the damper 2011; the damper 2011 and the shock absorbing spring 2012 cooperate to achieve the effect of shock absorbing the fixed cylinder 2013.
[0038] It should be noted that a mounting groove 2014 is provided on the inner right side wall of the bell-shaped housing 1, so that the shock-absorbing spring 2012 and the damper 2011 can be installed more stably. The shock-absorbing spring 2012 is located on the outside of the damper 2011 to ensure that the shock-absorbing spring 2012 can produce the expected deformation.
[0039] In addition, the right side of the shock absorbing spring 2012 and the right side of the damper 2011 are both fixed in the mounting groove 2014, so that the shock absorbing spring 2012 and the damper 2011 are installed more stably.
[0040] In addition, the left side of the shock absorbing spring 2012 is fixed to the inner left side wall of the fixed tube 2013 to fix the shock absorbing spring 2012. The outer diameter of the shock absorbing spring 2012 is equal to the inner diameter of the fixed tube 2013, so that the shock absorbing spring 2012 is installed more stably in the fixed tube 2013.
[0041] At the same time, the outer diameter of the shock-absorbing spring 2012 is equal to the diameter of the mounting groove 2014, the outer diameter of the shock-absorbing spring 2012 is equal to the diameter of the mounting groove 2014, the fixing tube 2013 is a rubber tube, and the fixing tube 2013 is made of hard nitrile rubber, which can effectively prevent the parts in the car's ball cage from rubbing against the fixing tube 2013 when they contact, thereby causing damage to the parts in the car's ball cage, ensuring the normal use of the parts in the car's ball cage, and the hard nitrile rubber has a high strength, which can effectively prevent the fixing tube 2013 from deforming during use, ensuring that the expected use effect is achieved.
[0042] In this embodiment, the fixing assembly 300 is a structure for fixing the CV cage in the vehicle.
[0043] like Figure 1 As shown, the fixing assembly 300 includes a fixing rod 301 fixed to the right side of the bell housing 1, a limiting sleeve 302 fixedly installed on the outside of the fixing rod 301, a bearing body 303 rotatably installed on the outside of the fixing rod 301, and an external spline 304 opened on the right side of the fixing rod 301.
[0044] It should be noted that the left side of the bearing body 303 is in close contact with the right side of the bell housing 1, and the left side of the limiting sleeve 302 is in close contact with the right side of the bearing body 303, ensuring that the bearing body 303 and the limiting sleeve 302 are installed more stably.
[0045] In addition, the diameter of the left end of the fixing rod 301 is smaller than the diameter of the right side of the bell housing 1, ensuring that the left side of the bearing body 303 can be in close contact with the right side of the bell housing 1, thereby making the bearing body 303 more stably installed.
[0046] The working principle of the above embodiment is:
[0047] When in use, the inner ball cage is connected to the internal structure of the automobile through the inner spline 203 and the outer spline 304, and the inner ball cage of the automobile is effectively fixed by using structures such as the fixing rod 301 in conjunction with the inner spline 203 and the outer spline 304, thereby ensuring that the inner ball cage is installed at the location where it needs to be installed. Then, during use, when the automobile encounters a bumpy road section, the tripod bearing 202 will squeeze the fixing cylinder 2013 due to the bumps, thereby squeezing the shock-absorbing spring 2012 and the damper 2011 through the fixing cylinder 2013. At the same time, the restoring elastic force of the shock-absorbing spring 2012 and the acting force of the damper 2011 also act on the tripod bearing 202 through the fixing cylinder 2013, thereby achieving a shock-absorbing effect, thereby effectively improving the stability and service life of the internal parts of the automobile inner ball cage, and improving the practicality of the automobile inner ball cage.
[0048] Compared with the prior art, the automobile inner ball cage, through the coordinated use of the bell-shaped shell 1, the plum blossom retaining ring 2, the shock-absorbing structure 200 and the fixing assembly 300, can provide a shock-absorbing effect for the inner ball cage itself, thereby effectively improving the stability and service life of the internal parts of the automobile inner ball cage, thereby effectively avoiding the need for frequent maintenance or replacement of the internal parts of the inner ball cage, reducing the use cost of the automobile inner ball cage, making it more convenient to use, improving the practicality of the automobile inner ball cage, and solving the problem of low practicality of the existing automobile inner ball cage.
[0049] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
