Fig. 1 is the partial side view of the operating stem assembly of the gear shift lock device be provided with according to the first preferred embodiment of the present invention;
Fig. 2 is the worm's eye view of the operating stem assembly of Fig. 1; And
Fig. 3 is the side view of the operating stem assembly of the gear shift lock device be provided with second embodiment of the invention.
Embodiment
Present general is hereinafter with reference to the accompanying drawings in detail with reference to the preferred embodiment of the present invention.To no longer describe with essence of the present invention other parts incoherent of automatic transmission operating stem assembly, and the parts do not described can be used prior art by former state or make to be suitable for the present invention by amendment prior art and be applied to the present invention.
Fig. 1 is the partial side view of the operating stem assembly of the gear shift lock device be provided with according to the first preferred embodiment of the present invention.In Fig. 1, operating stem assembly is the form bar type that operating stem forms the movement locus in zigzag form.As shown in Figure 1, operations according to the instant invention bar assembly 1 comprises pedestal (not shown), bar 20, rotating member 30, gear shift lock cam 40, electromagnet 50 and connector 60.
Bar 20 comprises the knob (not shown) being arranged on its end, makes driver catch this knob with the motion of controlling rod 20.The rotating member 30 joining the lower end of bar 20 to rotates to change speed change pattern according to the motion of bar 20 around axle 15, and rotating member 30 be included in lock the sticking department 150(that corresponding position formed with gear shift and see Fig. 2).Preferably, sticking department 150 is holding claws, and this holding claws is formed as making to be captured by the arm 41 of the gear shift of description lock cam 40 after a while, but sticking department 150 is not limited to particular form.
Gear shift lock cam 40 comprises: the first arm 41, and this first arm 41 is captured to sticking department 150 and rotates to prevent rotating member 30; Be attached with the second arm 42 of permanent magnet 45; And the 3rd arm 43.Second arm 42 is arranged to towards electromagnet 50, and permanent magnet 45 is attached to the second arm 42 and towards electromagnet 50.When the second arm 42 contacts with electromagnet 50, the 3rd arm 43 becomes and does not contact with the noise control pad 53 being set to pedestal.When the second arm 42 does not contact with electromagnet 50, the 3rd arm 43 becomes and contacts with noise control pad 53.But the 3rd arm 43 can not contact with electromagnet 50 all the time.And noise control pad 53 can not be set to pedestal, but be set to the top of electromagnet.
Preferably, electromagnet 50 also comprises another noise control pad 52 at the part place of the second arm 42 be arranged on towards gear shift lock cam 40.This noise control pad 52 can ensure smooth operation, this is because it not only prevents noise but also prevents permanent magnet 45 from contacting with the direct of electromagnet 50.When gear shift lock cam 40 directly contacts with electromagnet 50, due to the magnetization of the metal in electromagnet, and electromagnet is had become the possibility of permanent magnet, therefore, preferably, prevent permanent magnet 45 from directly contacting with electromagnet 50.
Torsion spring additionally can be set to the running shaft 47 of gear shift lock cam 40.That is, when electric current does not flow to electromagnet 50, gear shift lock cam 40 turns back to its home position due to gravity, permanent magnet 45 is made to tend to towards the metal in electromagnet, in this case, return for the ease of gear shift lock cam 40, additionally torsion spring can be installed.
Connector 60 is connected with break side, and when operational brake (not shown), this connector makes current direction electromagnet 50 have magnetic to make this electromagnet, but when break shut-down operation, this connector prevents current direction electromagnet.In this embodiment, the magnetic force formed at electromagnet 50 place is the magnetic force of the repulsion producing opposing permanent magnet 45.
Meanwhile, according to the amendment of the first preferred implementation, electromagnet can be arranged on gear shift lock cam 40 and permanent magnet can be arranged on position towards this electromagnet, and therefore, this layout belongs to scope of the present invention.
Then, the operation of the device shown in Fig. 1 and Fig. 2 will be described.
When driver tramples break, the signal of break is transmitted by connector 60, so, current direction electromagnet 50.
When electric current flows into electromagnet 50, that this electromagnet 50 becomes magnetic thus produce the repulsion of permanent magnet 45 of opposing gear shift lock cam 40, make gear shift lock cam 40 and rotate along the counter clockwise direction of Fig. 1.When gear shift lock cam 40 rotates in the counterclockwise direction, the holding claws 150 capturing rotating member 30 rises therefore rotating member 30 with the first arm 41 preventing this rotating member 30 from rotating and can rotate around running shaft 15.In the above-described state, when driver activates transmission operating bar, rotating member 30 rotates to the position wanted, thus can change speed change pattern.Holding claws 150 is set to the position corresponding with the gear needing gear shift to lock, and is not set to the gear not needing gear shift to lock.When break stops, electric current does not flow to electromagnet 50, therefore, between the permanent magnet 45 that gravity is applied to gear shift lock cam 40 and electromagnet 50, makes gear shift lock cam 40 and turns back to its home position.When additionally arranging torsion spring, gear shift lock cam 40 can turn back to its home position more swimmingly.In this case, when the second arm 42 turns back to electromagnet 50, permanent magnet 45 contacts with noise control pad 52.
If electromagnet is set to gear shift lock cam 40 and permanent magnet is arranged to towards electromagnet, so the present invention can provide release gear shift lock with the structure making to be suitable for this layout.
Fig. 3 is the side view of the operating stem assembly according to the second preferred embodiments of the present invention.Fig. 3 shows the movement locus straight-bar type linearly of transmission operating bar.Straight-bar type make driver can by pressing be set to the knob of transmission operating bar button and between particular gears change speed.
As shown in Figure 3, comprise according to the transmission operating bar assembly of the second preferred embodiments: pedestal 110; Bar 120; Be set to the knob button 130 of the end of bar 120; Can the locating stud 140 of vertical movement according to the operation of knob button 130; Gear shift lock cam 150; Electromagnet 160; And connector 170.
Bar 120 comprises guide portion 125, and locating stud 140 can move slidably along this guide portion 125.Gear shift lock cam 150 can rotate around running shaft 153, and comprise towards electromagnet 160 arm 152 and be set to the permanent magnet 155 of this arm 152.
Preferably, electromagnet 160 comprises the noise control pad 162 towards gear shift lock cam 150.This noise control pad 162 is used as the function identical with previously described noise control pad 52.
Gear shift lock cam 150 comprises holding claws 154.When locating stud 140 is captured to holding claws 154, prevent speed change pattern from changing, even if this is because driver promotes knob button 130 locating stud 140 can not move.In this case, when driver tramples break, the signal of break is transmitted by connector 170, so electric current flows into electromagnet 160.When electric current flows into electromagnet 160, electromagnet 50 produces the repulsion of opposing permanent magnet 155, thus gear shift lock cam 150 rotates around running shaft 153 in the counterclockwise direction.Then, as shown in Figure 3, locating stud 140 discharges from holding claws 154, and when driver promotes knob button 130, and locating stud 140 is along guide portion 125 slide downward thus change gear.
And in the second preferred implementation, the layout of electromagnet and permanent magnet can be put upside down.
Although reference specifically illustrated mode of execution describes the present invention, the present invention is not subject to the restriction of mode of execution and/or accompanying drawing and is only subject to the restriction of appended claim.It should be understood that when do not depart from as appended claim set forth the spirit and scope of the present invention, those skilled in the art can carry out various amendment, change and equivalent to substitute.
