Abstract
The utility model provides a parking gear locking device for an automatic automobile gear shifting lever assembly. The parking gear locking device comprises a magnetic valve and a parking gear microswitch, which are arranged on a base of a gear shifting mechanism; the magnetic valve is connected with a control cam of the gear shifting mechanism, and can respond to signals from the parking gear microswitch and a brake pedal and promote the pull-in action of the magnetic valve to be applied to the control cam for movement; when the magnetic valve is switched on, the control cam drifts leftwards, and a lever body locating pin is positioned in an unlocking state, so that an easy-to-control force can be used for operating the gear shifting lever conveniently.
Description
Technical field
The utility model relates to a kind of gear of the parking for vehicle automatic gear shifting bar assembly Locking Device.
Background technique
For the self shifter bar assembly of automobile, parking gear Locking Device is used mechanical structure conventionally.As shown in Figure 1, traditional mechanical parking gear Locking Device generally includes locking bracing wire 3, and its one end is connected on the control cam 4 of gearshift, and the other end is provided with two keying structures 1 and 2, and they connect respectively ignition key and brake petal.Between ignition key and brake petal, adopt tandem keying structure, only have when ignition key is on positi and could release when simultaneously brake petal is operated.Now, gear level 5 can swap out from parking gear.
Yet this parking gear Locking Device that comprises locking bracing wire is more complicated structurally, and the installation of locking bracing wire is conventionally also more difficult.In addition, when gear level is hung up from parking gear, shaft locating stud need to overcome the resistance of bracing wire self and the Returnning spring power of controlling cam simultaneously, and the gear shifting force that shaft locating stud acts on handle of shift lever button by driver moves, therefore this gear shifting force is wayward, easily bigger than normal and cause driver uncomfortable.
Model utility content
For the problems referred to above, the utility model aims to provide a kind of gear of the parking for vehicle automatic gear shifting bar assembly Locking Device, and it can control gear shifting force effectively.
The utility model provides a kind of gear of the parking for vehicle automatic gear shifting bar assembly Locking Device, comprises solenoid valve and parking gear sensitive switch on the base that is arranged on gearshift.Solenoid valve is connected with the control cam of gearshift, and can actuate and control cam generation motion in response to the signal from parking gear sensitive switch and brake petal.
In one embodiment, solenoid valve is connected by pull bar rigidly with controlling between cam.
In one embodiment, parking gear Locking Device comprises gear level shaft locating stud and the spring being associated with gear level shaft locating stud.
In one embodiment, solenoid valve disconnects under original state, and make to control the restoring force of cam by the spring in solenoid valve and act on pull bar, thus the stroke of restriction gear level shaft locating stud.In addition, solenoid valve can in response to the signal from parking gear sensitive switch and brake petal, closure be actuated control cam offset, thus release gear level shaft locating stud.
According to the utility model, the power of impelling the power of shaft locating stud from lockup state to released state to be acted on gear level by driver provides, and this power only need to overcome the spring force of spring itself.Than traditional mechanical parking gear Locking Device (wherein gear shifting force need to overcome the resistance of bracing wire itself and the spring force of spring itself), gear shifting force is easily controlled, and especially can be not bigger than normal.
Accompanying drawing explanation
To introduce with reference to the accompanying drawings the utility model below.
Fig. 1 has shown traditional mechanical parking gear Locking Device.
Fig. 2 A and 2B have shown according to the perspective view of parking gear Locking Device of the present utility model.
Fig. 2 C and 2D are respectively the partial enlarged drawings of Fig. 2 A and 2B.
Fig. 2 E and 2F are the partial enlarged drawings of Fig. 2 A and 2B, have shown respectively after solenoid valve is connected front and connection and have controlled the state between cam and gear level shaft locating stud.
Embodiment
Fig. 2 A and Fig. 2 B have shown respectively according to the perspective view of parking gear Locking Device 10 of the present utility model.As shown in Figure 2 A, this parking gear Locking Device 10 comprises the solenoid valve 12 on the base 11 that is arranged on gearshift.Solenoid valve 12 has more clearly demonstration in Fig. 2 C.Parking gear Locking Device 10 also comprises the parking gear sensitive switch 18 on the base 11 that is arranged on gearshift, as shown in Fig. 2 B and 2D.
According to the utility model, solenoid valve 12 is configured to be connected with the control cam 13 of gearshift.Controlling cam 13 is the known components in parking gear Locking Device, and its restoring force by the spring 15 in solenoid valve 12 acts on the shaft locating stud 14 of gear level.As shown in Figure 2 E, under original state, control cam 13 acts on pull bar 16 by the restoring force of the spring 15 in solenoid valve 12, thereby the stroke moving down of restriction shaft locating stud 14 causes gear level 20 to move.
In a specific embodiment, solenoid valve 12 is shown in Fig. 2 E by pull bar 16() be connected rigidly with the control cam 13 of gearshift.In addition, solenoid valve 12 be also configured to and parking gear sensitive switch 18 and the brake petal of automobile between signal communication.That is, solenoid valve 12 can be accepted from the signal of parking gear sensitive switch 18 and from the signal of brake petal.
As shown in Figure 2 E, according to the utility model, when parking gear Locking Device 10 is under original state, control cam 13 acts on pull bar 16 by the restoring force of the spring 15 in solenoid valve 12, thereby the stroke moving down of restriction shaft locating stud 14, causes gear level 20 to move.When the brake petal of automobile is operated and when parking gear is actuated, from the signal of brake petal with from the signal of parking gear sensitive switch 12, be delivered to solenoid valve 12 simultaneously, cause solenoid valve 12 closures.Now, solenoid valve 12 attracts to control cam 13 and moves to the left side in figure, thereby discharges locating stud 14.Therefore, shaft locating stud 14 is just no longer controlled the position-limiting action of cam 13, thereby in released state, so the power that just can act on handle button by driver realizes movement.In this case, gear level 20 can freely move and hang up from parking gear.
According to the utility model, the power of impelling the power of shaft locating stud 14 from locking to released state to be acted on gear level 20 by driver provides, and this power only need to overcome the spring force of spring 15 own.Therefore, gear shifting force is easily controlled, and especially can be not bigger than normal.
The foregoing is only preferred implementation of the present utility model, but the utility model protection domain is not limited to this.Any those skilled in the art, in the disclosed technical scope of the utility model, all can carry out suitable change or variation to it, and this change or change and all should be encompassed in protection domain of the present utility model within.
