Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the drawings attached to the specification.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

Example one

Referring to fig. 1 to 2, this embodiment discloses a signal panel for camshaft, including disk body 1, disk body 1 is the bowl form stamping workpiece, and the bowl form outward flange is bent and is had the breach for the round, keyway 2 has still been seted up at disk body 1 center, still be equipped with signal tooth 3 on the edge of disk body 1, signal tooth 3 sets up the breach department of bending at the round, sets up to the bowl form stamping workpiece through disk body 1, greatly reduced disk body 1's weight and processing cost, and simultaneously, disk body 1 compact structure is integrative, and the structural design space of relative positioning tooth is less to make disk body 1 occupy assembly space little.

The disc body 1 is positioned and combined on a camshaft journal through the key groove 2, meanwhile, the diameter of the disc body 1 is determined according to the position of the sensor, in the embodiment, the thickness of the disc body is 5-15mm, the weight of the signal disc is reduced, and light weight is achieved.

The key groove 2 is divided into an upper part and a lower part, the upper part is a rectangular groove, the lower part is a circular hole groove which is concentric with the disc body 1, and the rectangular groove and the circular hole groove are combined to form the key groove 2.

The angle α formed by the two side edges of the signal tooth 3 is 60 degrees, and the angle β formed by the signal tooth 3 and the vertical central line of the disc body 1 is 0-180 degrees.

The working principle of the embodiment is as follows: the proper disc body 1 is well selected through the position determination of the sensor, the disc body 1 is positioned and combined on the camshaft journal through the key groove 2, and signals on the signal teeth 3 are read through the sensor; through setting up this signal panel into the bowl form stamping workpiece, the weight and the processing cost of greatly reduced signal panel, the compact structure of signal panel is integrative simultaneously, and the structural design space of relative location tooth is less to make the occupation assembly space of this signal panel little.

Example two

Referring to fig. 3, the difference between the present embodiment and the first embodiment is that a plurality of lightening holes 4 are further provided on the disc body 1 around the key slot 2, in the present embodiment, the lightening holes 4 are kidney-shaped holes, the number of the lightening holes is four, and the weight of the signal disc is further reduced by the arrangement of the lightening holes 4, so as to achieve light weight.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
