Description

Pinion component on steering wheel angle sensor

Technical field

It the utility model is related to steering wheel angle sensor, and in particular to the pinion group on steering wheel angle sensor Part.

Background technology

Steering wheel angle sensor is the sensor for detecting steering wheel rotational angle and angular speed, has two in its part The pinion of individual carry magnet, and technique common at present is to be secured together magnet and this wheel by way of quadric injection mould, Technology difficulty is higher.

The content of the invention

The utility model in view of the above-mentioned problems, provide the pinion component on steering wheel angle sensor, by magnet with Gear is first individually made two parts, then is assembled together by mounting structure, reduces technology difficulty, also allow for subsequent resolution and Change.

In order to solve the above technical problems, the technical scheme that the utility model uses is：On steering wheel angle sensor Pinion component, including pinion and magnet, pinion is cyclic structure, magnet for matching pinion inner ring cylinder knot Structure, pinion and the detachable assembling of magnet are integral.

As the preferred of such scheme, the inner ring of pinion is stepped in the axial direction, the inner ring specifically include by The first inner ring, the second inner ring that most inner side is outwards sequentially distributed, the thickness of the first inner ring are less than the thickness of the second inner ring；

First inner ring has the first groove of at least one both ends open extended in the axial direction, and the depth of the first groove Difference of the degree less than the internal-and external diameter of the first inner ring；

Also there is the second groove, the quantity of the second groove at least two, the second groove is interior to be set along axle in first inner ring The elastic component of line direction extension, elastic component one end are fixed in inner ring, and the other end has to away from the convex of inner ring edge direction extension Rise, the length of elastic component is more than the thickness of the first inner ring；

Magnet is boss-shaped cylinder, and it specifically includes the lower prop with larger external diameter and the upper prop with smaller external diameter Body, column body outer wall have and can be arranged on the rib of the first fit depressions, rib in the first groove.

As the preferred of such scheme, the thickness of lower prop is equal in raised and the first inner ring between raised end face Distance.

As the preferred of such scheme, the quantity of groove has three, and is symmetrically distributed on inner ring side；Elastic component has three It is individual, and be symmetrically distributed on inner ring side.

As the preferred of such scheme, the thickness of rib is no more than column body and the difference of the external diameter of lower prop.

The beneficial effects of the utility model are：Magnet and gear are first individually made two parts, then pass through mounting structure It is assembled together, reduces technology difficulty, also allow for subsequent resolution and replacing.

Embodiment

With reference to embodiment, specific embodiment of the present utility model is further described.

As Figure 1-4, the pinion component on steering wheel angle sensor, including pinion 1 and magnet 2, pinion For cyclic structure, magnet is the column structure of matching pinion inner ring, and pinion and the detachable assembling of magnet are integral.

The inner ring of pinion is stepped in the axial direction, and the inner ring specifically includes what is be outwards sequentially distributed by most inner side First inner ring 11, the second inner ring 12, the thickness of the first inner ring are less than the thickness of the second inner ring；

First inner ring has the first groove 111 of at least one both ends open extended in the axial direction, and the first groove Depth be less than the first inner ring internal-and external diameter difference；

Also there is the second groove 112, the quantity of the second groove at least two, the second groove is interior to set edge in first inner ring The elastic component 13 of axis direction extension, elastic component one end are fixed in inner ring, and the other end has to away from the extension of inner ring edge direction Projection, the length of elastic component is more than the thickness of the first inner ring；

Magnet is boss-shaped cylinder, and it specifically includes lower prop 21 with larger external diameter and with the upper of smaller external diameter Cylinder 22, column body outer wall have and can be arranged on the rib 23 of the first fit depressions, rib in the first groove.

The thickness of lower prop is equal in raised and the first inner ring close to the distance between raised end face.

The quantity of groove has three, and is symmetrically distributed on inner ring side；Elastic component has three, and is symmetrically distributed in inner ring side On.

The thickness of rib is no more than column body and the difference of the external diameter of lower prop.

Wherein, in the present embodiment, the depth of the second groove is equal to the difference of the internal-and external diameter of the first inner ring.

Wherein, in the present embodiment, the quantity of rib has six, wherein three coordinate with the first groove, the other three and bullet Property part coordinate, be easily installed magnet.

During installation, pinion, rib extruding elastic component so that lower prop position are inserted in column body side where projection on magnet Between raised and the first inner ring, projection blocks column body outer face.

For those skilled in the art, the technical scheme described in foregoing embodiments can still be repaiied Change, or equivalent substitution is carried out to which part technical characteristic, all within the spirit and principles of the utility model, that is made is any Modification, equivalent substitution, improvement etc., should be included within the scope of protection of the utility model.
