Description
Technical field
The utility model belongs to electronic control system of dual-clutch automatic transmission technical field, and more particularly to a kind of installation is fixed
Gear position sensor component on case of transmission.
Background technology
In dual-clutch transmission electric-control system, the effect of gear position sensor (PRNDS position sensors)
It is that the gear shift operation intention of driver is reflected to transmission control unit, it is desirable that the signal that sensor provides is accurately reliable.Shelves
Position position sensor acquisition signal operation principle be：The position of handle bar is changed into the angle of parking axis by mechanical connection
Degree rotation, the through-hole rotor of sensor are connect with parking axis shaft hole matching, and the housing of sensor is fixed on case of transmission.It passes
Sensor acquires the rotational angle of parking axis by rotor, and angle is converted into signal and issues transmission control unit.
The installation and locating method of general gear position sensor is exactly after sensor through-hole rotor is passed through parking axis, to use
Bolt tightens the threaded hole fixation on sensor fixing hole and case of transmission.
But this conventional fastening method is not very accurate, the consistency of sensor positioning to the position positioning of sensor
It is bad, the deviation of signal of sensor can be caused, especially when effective rotation angle range of parking axis is smaller, this deviation is very
The positioning failure of sensor gear can extremely be caused.The reason is that there is also normal mechanical tolerance between gear box casing and parking axis,
It is more importantly clearance fit between the circular fixation hole of PRNDS sensors and installation bolt, this leads to two circles of sensor
Before the bolt of shape mounting hole is not tightened completely, sensor still can be using parking axis as the center of circle, small angle clockwise or counterclockwise
The rotation of degree.Installation bolt is tightened at this time, when sensor is fixed on case of transmission, physical location and the theory of sensor
Position will be there are the deviation of a low-angle, this angle signal for resulting in PRNDS sensors has mistake bigger than normal or less than normal
Difference.
Utility model content
The utility model aim is to provide a kind of gear position sensor component, and which solve due to proper tolerances and gap
Cooperation causes sensor signal error to be caused there are the deviation of low-angle even to lose between the physical location of sensor and theoretical position
The existing issue of effect.
The utility model solves technical problem and adopts the following technical scheme that：A kind of gear position sensor component, including
Gear position sensor and fixture；
Two locating slots, and the cross section of the mounting hole of the housing are opened up on the housing of the gear position sensor
For oblong；
The fixture includes substrate and claw, and flat hole is offered on the substrate, and the flat hole is cut with parking axis
Face is identical, and the substrate is fixed in one end of the claw, and the other end is arranged on the housing of the gear position sensor
In groove.
Optionally, the quantity of the claw is two, and is mutually parallel between two claws.
Optionally, the width of the claw is more than the width of the locating slot.
Optionally, the width of the claw is more than the width 0.5mm of the locating slot.
The utility model has the advantages that：The gear position sensor component of the utility model is by original gear position
The fixed form of sensor is put, by the clearance fit between the housing and case of transmission of gear position sensor, becomes gear
Interference fit between the housing of position sensor and parking axis, gear position sensor position when avoiding original mounting means
It is uncertain, ensure that the installation accuracy and signal accuracy of gear position sensor.

Specific embodiment
The technical solution of the utility model is further elaborated with reference to embodiment and attached drawing.
Embodiment 1
A kind of gear position sensor component is present embodiments provided, including gear position sensor and fixture 1.
Two locating slots 3, and the horizontal stroke of the mounting hole 4 of the housing are opened up on the housing 2 of the gear position sensor
Section is oblong.
The fixture includes substrate 11 and claw 12, and in the present embodiment, flat hole, the flat are offered on the substrate
Hole is identical with the section of parking axis, and the substrate is fixed in one end of the claw, and the other end is arranged in the gear positions and passes
In groove on the housing of sensor.
Preferably, the quantity of the claw is two, and is mutually parallel between two claws, and the width of the claw is slightly larger
In the width of the locating slot, for example, the width of the claw is more than the width 0.5mm of the locating slot, so that the card
It is interference fitted between pawl and locating slot.
The gear position sensor component of the utility model passes through parking when in use, by the rotor of gear position sensor
Axis, it is fixed thereto in a manner of shaft hole matching；The flat hole of fixture is passed through into parking axis, sensing station is adjusted, by the two of fixture
A claw is put at the two of sensor in locating slot, the position between fixed sensor housing and parking axis；It will be sensed with bolt
Device is fixed on gear box casing, takes out fixture, completes the installation positioning of gear position sensor.
As a result, in the utility model, by the way that the cross section of the mounting hole of gear position sensor is changed by common circular hole
For oblong, after fixture positions, the small angle rotation adjustment of the housing of gear position sensor centered on parking axis；It is fixed
Position between gear position sensor housing and parking axis greatly reduces the deviation of signal of gear position sensor, protects
The consistency and accuracy of the installation accuracy signal of gear position sensor are demonstrate,proved.
That is, the gear position sensor component of the utility model is by the fixed form of original gear position sensor, by shelves
Clearance fit between the housing and case of transmission of position position sensor becomes the housing of gear position sensor and parking axis
Between interference fit, gear position sensor position is uncertain when avoiding original mounting means, ensure that gear positions
The installation accuracy and signal accuracy of sensor.
The sequencing of above example is not only for ease of description, represent the quality of embodiment.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
