Detailed Description
As shown in fig. 1-3, the dust cover for the steering rod of the motor vehicle provided by the utility model comprises a dust cover main body 1, wherein the dust cover main body 1 is of a non-axisymmetric structure with one high side and one low side, the upper end of the dust cover main body 1 is provided with a fixed port 2, the middle of the dust cover main body 1 is provided with a buffer cavity 3, and the bottom of the dust cover main body 1 is provided with a fixed ring pad 4; the upper end of the fixed ring pad 4 is provided with a mounting ring pad 5, and a brake anti-lock braking system mounting bracket mounting groove 6 is reserved between the fixed ring pad 4 and the mounting ring pad 5.
As shown in fig. 4-5, the dust cover main body 1 is sleeved at the lower end of the steering rod 9 of the motor vehicle, and the fixing port 2 is tightly matched with the steering rod 9 of the motor vehicle. Then, the fixing ring pad 4 of the dust cover main body 1 is mounted at the bottom of the anti-lock brake system mounting bracket 8, the mounting ring pad 5 is mounted at the upper end of the anti-lock brake system mounting bracket, and the side edge of the middle hole of the anti-lock brake system mounting bracket 8 is positioned in the anti-lock brake system mounting bracket mounting groove 6, namely, the dust cover main body 1 is mounted on the anti-lock brake system mounting bracket 8. Finally, the anti-lock brake system mounting bracket 8 is mounted in the body of the motor vehicle using screws or the like, that is, the dust cover main body 1 is fixed to the body of the motor vehicle. The utility model does not need to use bolts to fix the dust cover main body 1, has simple installation and operation, improves the installation efficiency and saves the cost. The fixed ring pad 4 is positioned at the bottom of the anti-lock brake system mounting bracket 8, is tightly sealed, and does not allow dust, sand and other foreign matters to enter the steering shaft gap.
