Abstract
The utility model provides an angle sensor (3) of electronic pedal, which comprises a sensor rotating axis (5), an axletree (6), a magnetic stick (7), a magnetic sensitive element (8), a screen cover (9) for the magnetic sensitive element, a sensor housing (10), a control circuit (11), a backward cover (12) and a wiring harness (13). The magnetic sensitive element (8) is provided in the screen cover (9) for the magnetic sensitive element. The screen covers (9) for the magnetic sensitive element and the magnetic sensitive element (8) are provided in a cylinder hole (14). The control circuit (11) is fixed on an end face (16) of the sensor housing (10). The backward cover (12) is embedded into the sensor housing (10) and covers the control circuit (11). The angle sensor of electronic pedal is simple structure, convenient assembly and good screen effect.
Description
Technical field the utility model relates to a kind of electronic pedal sensor, is particularly useful for haulage vehicle.
Background technology is present, known electronic pedal angular transducer assembly structure complexity, and shield effectiveness is not good.
Usually the electronic pedal angular transducer adopts magneto sensor to take measurement of an angle, because the electronic pedal angular transducer is a safety member to vehicle, so it is extremely important that magnetic shielding just seems.
Summary of the invention is in order to ensure the reliable and simplified structure of electronic pedal angular transducer magnetic shielding, the utility model provides a kind of electronic pedal angular transducer, the mode that adopts magneto sensor and control circuit to shield respectively, and be contained in the all-in-one-piece housing, simplified the structure of electronic pedal angular transducer greatly.
The technical scheme that its technical matters that solves the utility model adopts is:
Electronic pedal angular transducer (3) is made up of sensor rotating shaft (5), bearing (6), bar magnet (7), magneto sensor (8), magneto sensor radome (9), sensor housing (10), control circuit (11), rear end cap (12) and wire harness (13).Magneto sensor (8) places in the magneto sensor radome (9), and magneto sensor radome (9) is inserted in the cylindrical hole (14) together with magneto sensor (8), and control circuit (11) is fixed on sensor housing (10) end face (15).Rear end cap (12) embeds in the sensor housing (10) again, covers control circuit (11) simultaneously.
The beneficial effects of the utility model are:
The electronic pedal angular transducer is simple in structure, and is easy to assembly, and shield effectiveness is good.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.

Embodiment
The detailed description of accompanying drawing:
Electronic pedal is formed (Fig. 1) by pedal 1, pedal base plate 2, swing arm 3, angular transducer 4.
Electronic pedal angular transducer 4 is formed (Fig. 2,3,4) by sensor rotating shaft 5, bearing 6, bar magnet 7, magneto sensor 8, magneto sensor radome 9, sensor housing 10, control circuit 11, rear end cap 12 and wire harness 13.
Bar magnet 4 is embedded in the groove of sensor rotating shaft 5 terminations, and sensor rotating shaft 5 is bearing in the cylindrical hole 14 of sensor housing 10 by bearing 6.Magneto sensor 8 places in the magneto sensor radome 9, and magneto sensor radome 9 is inserted in sensor housing 10 cylindrical holes 14 again, and makes magneto sensor 8 relative with bar magnet 7.Control circuit 11 is fixed on the end face 16 of control circuit installation cavity 15 (Fig. 4,5).Rear end cap 12 embeds in the groove 17 of sensor housing 10 again, covers control circuit 11 (Fig. 5).
Sensor housing 10 (Fig. 5,6) has breach 19 and breach 20 at sensor housing 10 tow sides between the cavity 18 of control circuit installation cavity 15 and sensor housing 10, the cavity 18 of control circuit installation cavity 15 and sensor housing 10 is connected.
The wire harness 13 of control circuit 11 is by breach 19 on the sensor housing 10 and the breach 21 on breach 20 and the rear end cap 12, enter the cavity 18 of sensor housing 10, hole 22 is used for alignment bundle 13, and wire harness 13 passes angular transducer 4 through sensor housing 10 breach 23.
For seal, protection against the tide, can be by breach 19 on the sensor housing 10 and the breach 21 on breach 20 and the rear end cap 12 notes fluid sealant in control circuit installation cavity 15 is installed.
Principle of work:
Step on electronic pedal, pedal 1 relative pedal base plate 2 angles change, and swing arm 3 is swung thereupon.Arm shaft drives sensor rotating shaft 5 rotations, and bar magnet 4 rotates thereupon.At this moment, the output quantity of magneto sensor 8 on the other side changes, and handles through control circuit 11, exports required electric signal.There are certain corresponding relation in this electric signal and pedal angle.
