Vehicle bearing press-mounting tool and method

Abstract

The invention provides a press mounting device of a vehicle bearing, which comprises a column-shaped guider and a column-shaped pressurizing device. The column-shaped guider is provided with a guiding part and a loading part, wherein, the diameter of the guiding part is determined according to the size of a hole on a steering axle for mounting a bearing, while the length of the guiding part is determined according to the mounting position of the bearing inside the hole on the steering axle; the diameter of the loading part is determined according to the internal diameter of the bearing, and the length of the loading part is determined according to the length of the bearing; the column-shaped pressurizing device is connected and fixed with the guider, the diameter of the pressuring device is identical with that of the guiding part, the pressuring device is provided with a ring-shaped bulge at the end connected with guider, the width of the bulge is determined according to the position of a sealing element of the bearing, and the length of the bulge is a pre-determined protective number.

Description

Technical field [0001] The present invention relates to the field of vehicle maintenance, and more specifically, to the press-fitting of vehicle bearings in the process of vehicle maintenance. Background technique [0002] The bearing of a vehicle is a very important part of the vehicle. If the bearing fails or is damaged, it will have a serious impact on the performance of the vehicle and driving safety. reference figure 1 , figure 1 Shows the location of the bearing in the vehicle. It should be noted, figure 1 The mechanism shown is the wheel structure where the drive shaft is located. For example, for a front-wheel drive vehicle, figure 1 Shown is the structure of the front wheel. reference figure 1 , The bearing 102 is placed in a hole 103 of the steering axle 104, and the limit ring 106, the baffle 108, the axle 110 and the brake disc 112 are installed in sequence and fixed by a nut 114. [0003] reference figure 2 As shown, figure 2 The structure of the bearing is sh...

AI Technical Summary

Problems solved by technology

[0005] 1) The force can only be applied to the outer metal shell, and the seal cannot be damaged, otherwise it will cause damage to the seal;

[0006] 2) The direction of the force must be accurate, and there must be no deviation, otherwise there will be a deviation in the position of the steel ball, or the steel ball will leave a pit on the slide rail;

[0007] 3) The applied force must be uniform, and the tilting of the bearing cannot occur. The tilting of the bearing will not only damage the bearing, but also destroy the structure of the hole 103 on the steering bridge 104 to a certain extent.

[0008] The above-mentioned requirements can be precisely controlled by computer in the automatic equipment of the manufacturer, but in the maintenance and inspection industry, it is impossible to have such a large and sophisticated equipment, which basically relies on manual operation, so the direction and uniformity of the applied pressure are not guaranteed

Therefore, the current situation is that the damage rate of the bearing installation is high, and the bearing is often damaged due to the inability to ensure a uniform and horizontal force direction.

In addition, after the bearing is installed, it should be in the middle of the hole 103 of the steering bridge 104, and there is a certain distance from both ends to ensure the safety of other parts. In manual safety, this distance cannot be grasped, often causing Multiple disassembly and assembly, which increases the possibility of damage to bearings or steering axles
