Embodiment
The of the present invention structure expressed as Fig. 1 to Fig. 5, the present invention is a kind of clutch position sensor connector of automatic gearbox, comprise set clutch oil cylinder piston 3 and clutch position sensor 8 in clutch oil cylinder 9 in the clutch actuator, the clutch oil cylinder 9, establish sensor axis 7 in the clutch position sensor 8, and adopt two mounting holes 10 on the sensor cover 4 that whole sensor is fastened on the clutch oil cylinder cylinder body 6.Sensor axis 7 produces electrical signal by the variation of position, the variation of this position is passed to sensor axis 7 by the motion generation of clutch oil cylinder piston 3 set in the clutch oil cylinder 9 and by the sensor connection set, the electrical signal that is produced is connected with the speed Control unit by circuit, make the speed Control unit to make and judge and decision-making, and send the corresponding action instruction according to the physical location of clutch.
The present invention is for solving problem related in background technique and overcoming its defective, following technological scheme is proposed: as shown in Figure 1, clutch oil cylinder piston 3 in the clutch of automatic gearbox and sensor axis 7 are connected by slidercrank mechanism, clutch oil cylinder piston 3 is the slide block of this mechanism, if the sensor rocking arm 2 of fixedlying connected with sensor axis 7 and rotating around sensor axis 7 is the crank of this mechanism, establishes two ends and be the connecting rod of this mechanism with the sensor pull bar 1 that clutch oil cylinder piston 3 and sensor rocking arm 2 are articulated and connected respectively.The straight line motion of clutch oil cylinder piston 3 passes motion to sensor rocking arm 2 by sensor pull bar 1, sensor rocking arm 2 is produced rotatablely move, and drive sensor axis 7 rotations.Adopt the linkage mechanism of crank block type, make mechanism simplifying, rational in infrastructure, transmission is more reliable.
The present invention proposes first embodiment according to technique scheme:
As shown in Figure 1 and Figure 4, sensor pull bar 1 with the structure that is articulated and connected of clutch oil cylinder piston 3 is: sensor pull bar 1 and sensor rocking arm 2 are connected for carrying out hinge with pin; Sensor pull bar 1 with the Placement of clutch oil cylinder piston 3 is: sensor pull bar 1 is a spherical head 11 with clutch oil cylinder piston 3 connecting ends, on the axis of the end that clutch oil cylinder piston 3 is connected with sensor pull bar 1, if hemispheric piston end concave surface 12, if cross lining 5 is fastening with this end of clutch oil cylinder piston 3, cross lining 5 and clutch oil cylinder piston 3 junction surfaces and with the same position of clutch oil cylinder piston 3 end piston end concave surfaces 12, also establish a hemispheric lining end concave surface 13, the spherical head of described sensor pull bar 1 places in two formed cavitys of hemispheric concave surface and is Spielpassung, establish tie rod hole 14 on the axis of cross lining 5, sensor pull bar 1 passes from this hole.
As Fig. 1, Fig. 4 and shown in Figure 5, being fastenedly connected to groove-fastening type of described cross lining 5 and clutch oil cylinder piston 3 is connected, be that the endoporus of clutch oil cylinder piston 3 at this place is the cross recess 15 of cross transverse section, the transverse section of cross lining 5 be shaped as its corresponding cross, and cooperatively interact and be Spielpassung, at the place, aperture of clutch oil cylinder piston 3, clutch oil cylinder piston 3 is riveted joint with cross lining 5.The effect of cross recess 15 is the revolutions that prevent cross lining 5.This mounting type is more convenient in when maintenance dismounting, but loosening easily when using.
Second embodiment of the present invention is identical with first embodiment's basic structure, its difference is: being fastenedly connected in the hole for the end that cross lining 5 is pressed into clutch oil cylinder piston 3 of cross lining 5 and clutch oil cylinder piston 3, both are interference fit.The intensity that this riveting connects is bigger, be difficult for becoming flexible, but repair demolition is relatively more difficult.
The 3rd embodiment of the present invention is identical with first embodiment and second embodiment's basic structure, its difference is: described cross lining 5 is fastenedly connected to being threaded with clutch oil cylinder piston 3, be that the endoporus of clutch oil cylinder piston 3 at this place is internal thread, the cylindrical of cross lining 5 is an outside thread, and described internal and external screw thread forms screw-thread fit.This mode need be at the outer end of cross lining 5 tuorbillion clamping tool insertion groove, and the insertion of the screwing tool when screwing with convenient installation also works the effect of screwing.This mounting type is more convenient in when maintenance dismounting, but loosening easily when using.
The present invention on above-mentioned three embodiments' basis, the concrete mode that tie rod hole 14 is taked as shown in Figure 4, promptly tie rod hole 14 adopts the taper hole shapes, its towards the aperture of the outer end of sensor axis 7 greater than the inner aperture that communicates with lining end concave surface and locate.This mode had both guaranteed the intensity of cross lining 5, and particularly the aperture of tie rod hole 14 is excessive, and lining end concave surface 13 can't play the effect of restriction spherical head 11; Make sensor pull bar 1 when motion, can not interfere, run foul of each other and cause losing efficacy again with cross lining 5.
The present invention adopts technique scheme also by specific embodiment, adopt the linkage mechanism of crank block type, the straight line motion of clutch actuator is changed into the rotatablely moving of axle of clutch sensor, be about to straight-line displacement and be transformed into angular turn, simple in structure, easy to detect, the testing precision height.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
