Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] combine Figure 1 to Figure 3 As shown, the wheel hub bearing for installing the wheel speed sensor of ABS (Anti-lock Brake System) in this embodiment includes an inner ring 1 , an outer ring 2 and a sealing cover 3 . Wherein, the sealing cover 3 is located on the axial side of the outer ring 2, and is used to seal the hub bearing to prevent external pollutants (such as water, dust, etc.) from entering the bearing. In addition, the sealing cover 3 is also used for installing and fixing the ABS wheel speed sensor (not shown). In the technical solution of the present invention, the so-called axial direction refers to the axial direction of the bearing.

[0025] Specifically, the sealing cover 3 includes a cover body 32 and a skeleto...

Abstract

The invention discloses a hub bearing used for mounting a wheel speed sensor of an anti-lock brake system (ABS). The hub bearing comprises an outer ring, and a sealing cover located on one axial sideof the outer ring. The sealing cover is used for sealing the hub bearing, and comprises a cover body and a framework ring; the axial end, close to the outer ring, of the cover body is fixed to the framework ring, the framework ring is fixed to the outer ring, and the wheel speed sensor is used for being fixed to the cover body; and according to the cover body and the framework ring, the cover bodyis provided with embedded portions, the framework ring is provided with recessed portions, and the embedded portions are buried in the recessed portions in a relative rotation resistance manner, so that relative rotation resistance between the cover body and the framework ring is achieved. According to the hub bearing provided by the invention, under the effect of relative rotation resistance cooperation of the embedded portions on the cover body and the recessed portions in the framework ring, relative rotation between the framework ring and the cover body can be prevented, accordingly measuring results of the wheel speed sensor are not affected, and the situation that external pollutants enter the bearing due to relative rotation between the framework ring and the cover body is also avoided.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a wheel hub bearing used for installing an ABS wheel speed sensor. Background technique [0002] ABS (Anti-lock Brake System, anti-lock brake system) is an indispensable equipment for modern cars. It automatically controls the braking torque acting on the wheels and controls the slip rate of the wheels during braking to 10%. to 20%, so that the wheel and the ground are always kept near the peak adhesion coefficient for braking, so as to shorten the braking distance. ABS includes wheel speed sensors, electronic control units and brake actuators. ABS senses the wheel speed and body movement speed of the car through the wheel speed sensor installed on the wheel hub bearing, and obtains the two reference control variables of the relevant wheel acceleration and slip rate through a certain algorithm to achieve efficient and stable ABS control. [0003] The hub bearing is one of the ...
