Abstract
The utility model relates to an automotive angular transducer housing comprising an upper cover and a rear cover. A primary gear and a second gear engaged with the primary gear are arranged in the upper cover; a boss structure is arranged at the primary gear; and a first groove matched with the boss structure of the secondary gear is arranged at the upper cover. Preferably, the rear cover includes an outer case and a rear shell connected with the outer case. According to the scheme, because the boss structure of the secondary gear is aligned at the first groove of the upper cover, no phenomena of deviation and axial shaking of the gears occur during the rotating process, thereby improving the work stability. Moreover, the lubricating oil between the gears is prevented from spilling easily, thereby avoiding the circuit board from being polluted; and the structure of the housing is simple and the cost is low.
Description
Technical field
The utility model relates to automobile steering system annex, relates in particular to a kind of automobile angle sensor shell.
Background technology
Automobile angle sensor shell is the vitals that guarantees angular transducer steady operation.Existing angle sensor shell has various ways, and result of use is not all fine.More there is following problem in existing angle sensor shell: angle sensor shell is fixing firm not to gear, and gear has and departs from rotation process, causes product signal output poor accuracy, and the lubricating oil between gear easily overflows, and pollutes wiring board.
As Chinese Patent Application No. 201120472278.0, a kind of automobile angle sensor shell is disclosed, comprise back cover and upper cover, the inferior gear that is provided with main drive gear in described upper cover and is meshed with main drive gear; In described upper cover, be provided with inferior gear on the suitable boss of groove.On described, cover and be provided with the pickup groove that surrounds main drive gear and time gear.Although above-mentioned patent is located by boss is set on housing, gear can be offset in rotary course, improve working stability, if but need to make the lubricating oil between gear be difficult for overflowing, need to pickup groove be set upper covering, increase the complexity of enclosure interior structure.
Utility model content
The purpose of this utility model is to provide a kind of automobile angle sensor shell, and solved existing automobile angle sensor shell annular wheel and be easily offset in rotary course, and the problem of easily overflowing of the lubricating oil between gear.
The utility model solves the technical scheme that its technical matters adopts: a kind of automobile angle sensor shell, comprise upper cover and bonnet, the inferior gear that is provided with main drive gear in described upper cover and is meshed with main drive gear, inferior gear is provided with boss structure, covers on described and is provided with first groove suitable with the boss structure of inferior gear.Preferably, bonnet comprises shell and the back cover joining with this shell.
In order to make gear skew can not occur in rotary course and axially rock, improved the stability of work, on inferior gear, be also provided with the second groove, on described shell, be provided with the packing ring suitable with the second groove of inferior gear.Preferably, the second groove and packing ring are annular.
In order to ensure wiring board fixation, guarantee the stability of measurement of angle, on shell, be also provided with convex tendon.
The beneficial effects of the utility model: aim at the first groove covering by the boss structure on inferior gear, make gear skew can not occur in rotary course and axially rock, improve the stability of work, and made the lubricating oil between gear be difficult for overflowing, avoided wiring board to be polluted; Further, the ring washer matching with the second groove on time gear is set on shell, has further improved the stability of working; Shell is provided with the convenient parallel convex tendon of two rows that wiring board is installed, and guarantees wiring board fixation, guarantees the stability of measurement of angle.
Below with reference to drawings and Examples, the utility model is described in detail.
