Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the utility model, are within the scope of the utility model.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

As shown in fig. 1 and 2, a wheel speed sensor assembly according to the present invention includes: the wheel edge assembly 10 is provided with a mounting seat 11, the mounting seat 11 is provided with a mounting hole, the bushing 12 is arranged in the mounting hole, and the wheel speed sensor 13 penetrates through the bushing 12. Can be with fast sensor direct mount of wheel in the bush, need not use the bolt to install, simple and convenient has reduced during the assembly man-hour, the cost is reduced, and the length precision requirement of the fast sensor head of wheel is lower, even head length size discrepancy appears, also can the loading, has improved the product percent of pass.

Optionally, the method further comprises: pencil 14, the one end and the fast sensor 13 of wheel of pencil 14 are connected, are equipped with connecting piece 15 on the pencil 14, are convenient for fix pencil 14 or realize connecting through connecting piece 15, and connecting piece 15 can be the buckle, can set up the cassette on the wheel limit assembly, can be with the buckle joint on the cassette.

Optionally, the mounting hole is cylindrical, the bushing 12 is cylindrical, and the axis of the bushing 12 is collinear with the axis of the mounting hole, so that the mounting is facilitated.
