Description

Technical Field

[0001] The utility model relates to the field of automobile rear axles, in particular to a half-axle bearing seat of an automobile rear axle. Background Art

[0002] The rear axle of a car is an important part of the vehicle. It is located at the rear of the car and connected to the frame through the suspension. Wheels are installed at both ends, which is closely related to the power transmission of the vehicle. If the front axle is not a drive axle, then the rear axle is the drive axle. In this case, the rear axle not only bears the load, but also plays the role of driving, decelerating and differential. In four-wheel drive vehicles, there is generally a transfer case in front of the rear axle to better distribute power.

[0003] The rear axle is a device used to support and connect the wheels. It consists of two half-bridges, which can implement half-bridge differential movement. The rear axle is divided into a solid bridge and a half-bridge. The solid bridge is equipped with a non-independent suspension, such as a leaf spring suspension; the half-bridge is equipped with an independent suspension, such as a McPherson suspension.

[0004] Where there are bearings, there must be support points. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat. The bearing is a component that fixes and reduces the load friction coefficient during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. The bearing seat is a necessary accessory for supporting the rotation of the bearing, which can support the rotation of the bearing. Application number: CN202321572625.6, provides an automotive bearing seat that can adjust the direction of the adaptable shaft, realize the function of multi-stage direction adjustment, and improve practicality. However, when the device is in use, it is more troublesome to install, and the bearing cannot be quickly and stably installed. And if the bearing seat needs to be replaced after installation, it will be more cumbersome to disassemble.

[0005] Therefore, it is necessary to provide a kind of automobile rear axle half-shaft bearing seat to solve the above-mentioned technical problems. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a rear axle half-shaft bearing seat of an automobile provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of a cross-sectional view of a fixing plate shown; Figure 3 for Figure 1 The structural schematic diagram of the upper and lower bearing seats being separated is shown, and a bearing seat for a rear axle half shaft of an automobile comprises: a fixing plate 1, and a mounting assembly 2 is arranged on the inner side of the fixing plate 1;

[0023] The mounting assembly 2 includes a fixing frame 21 arranged on the top of the fixing plate 1, a lower bearing seat 22 is arranged on the inner side of the fixing frame 21, and reinforcement plates 23 are arranged on both sides of the fixing frame 21 so as to slide left and right, and the back sides of the two reinforcement plates 23 are tightly fitted with the front side of the lower bearing seat 22.

[0024] During installation, the lower bearing seat 22 is pushed toward the inside of the fixing frame 21, and then its back side is clamped on the inner side of the fixing frame 21. At this time, the two reinforcing plates 23 are pushed inward so that the two reinforcing plates 23 fix the front side of the lower bearing seat 22, thereby fixing the entire lower bearing seat 22 to the fixing plate 1.

[0025] A bidirectional threaded screw 24 is rotatably arranged inside the fixing plate 1, and the circumferential side surface of the bidirectional threaded screw 24 is threadedly connected to two threaded blocks 25 that can move left and right along its length direction. The opposite sides of the two threaded blocks 25 are fixedly connected to the sides separated from the two reinforcement plates 23 respectively.

[0026] By setting the reverse threads on the side surfaces of the bidirectional threaded screw rod 24, when it rotates, it will drive the two reinforcement plates 23 to move relative to or away from each other, thereby fixing or canceling the fixation of the lower bearing seat 22.

[0027] The left end of the bidirectional threaded screw 24 passes through the inner wall of the fixing plate 1 and extends to the left side thereof. A rotating handle 26 is provided at the left end of the bidirectional threaded screw 24 .

[0028] An upper bearing seat 3 is slidably disposed on the inner side of the lower bearing seat 22 , and threaded holes 4 are provided on both left and right sides of the top of the lower bearing seat 22 .

[0029] The inner sides of the two threaded holes 4 are rotatably connected with screw rods 5, the peripheral side surfaces of the two screw rods 5 are slidably connected to the inner side of the upper bearing seat 3, and gaskets 6 are provided on the peripheral side surfaces of the two screw rods 5 and on the top of the upper bearing seat 3.

[0030] The bottom of the screw rod 5 is slowly screwed into the bottom of the threaded hole 4 by rotating the screw rod 5, so that the distance between the upper bearing seat 3 and the lower bearing seat 22 is continuously reduced until the bearing on the opposite side is fixed.

[0031] An oil filling hole 7 is provided on the top of the upper bearing seat 3 .

[0032] The oil filling hole 7 can conveniently inject lubricating oil into the fixed position, reducing the trouble of oil filling.

[0033] The working principle of the automobile rear axle half-axle bearing seat provided by the utility model is as follows:

[0034] Step 1: During installation, push the lower bearing seat 22 toward the inner side of the fixing frame 21, and then clamp its back side on the inner side of the fixing frame 21. At this time, push the two reinforcing plates 23 inward so that the two reinforcing plates 23 fix the front side of the lower bearing seat 22, and then fix the entire lower bearing seat 22 to the fixing plate 1. Turn the screw 5 and slowly screw its bottom into the bottom of the threaded hole 4, so that the distance between the upper bearing seat 3 and the lower bearing seat 22 is continuously reduced until the bearing on the opposite side is fixed.

[0035] Step 2: When the bearing seat needs to be replaced, the two reinforcing plates 23 are driven to move away from each other by rotating the bidirectional threaded screw 24 in the opposite direction, thereby canceling the fixation of the front side of the lower bearing seat 22, and then the lower bearing seat 22 is moved forward and taken out, which greatly speeds up the disassembly and installation efficiency of the bearing seat.

[0036] Compared with the related art, the utility model provides a rear axle half-axle bearing seat of an automobile having the following features:
