Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a wheel hub bearing unit with a screw-in sensor mounting housing. Background Technology

[0002] Wheel hub units with ABS sensors are crucial components in modern automobiles, combining the functions of a wheel hub unit and an ABS (Anti-lock Braking System) sensor. The ABS sensor monitors wheel speed in real time, providing accurate data support for the ABS system. When abnormal wheel speed occurs, the ABS system reacts quickly to prevent wheel lock-up, thereby improving vehicle braking performance and driving safety. However, most sensors or sensor mounting housings currently on the market are designed with appropriate interference fits, using a press to press the sensor mounting housing into place.

[0003] This installation method requires special installation equipment and cannot be quickly disassembled, resulting in low efficiency. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings. A hub bearing unit with a screw-in sensor mounting housing includes an inner ring 1 and an outer ring 2. The inner ring is provided with a flange 3, and a retainer 11 is provided between the inner ring and the outer ring. The retainer is provided with rolling elements 111, and a gear ring 4 is also included, which is installed on the circumferential outer wall of the inner ring. A first threaded portion 110 is provided on the inner wall of the outer ring. The sensor mounting housing 5 has a convex ring 51 on its axial outer wall, and the outer wall of the convex ring has a second threaded portion that mates with the first threaded portion. A first clearance groove 12 is provided on the inner wall of the outer ring and is located opposite to the outer side of the first threaded portion. A second clearance groove 52 is provided at the connection between the convex ring and the sensor mounting housing and is located opposite to the first clearance groove. The sharp corners of conventional outer rings and the right angle at the connection between the convex ring and the sensor housing can easily cause interference and affect proper installation. The two clearance grooves provided in this application are more conducive to installation.

[0026] In this embodiment, as shown in the figure, the second clearance groove is an arc-shaped groove.

[0027] In this embodiment, as shown in the figure, the outer wall of the sensor mounting housing is in contact with the outer wall of the outer ring. This results in a more stable installation.
