Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 3, the utility model embodiment provides a kind of torsion bar Locking Device utilizing torsion bar to overturn wheel, be installed in amphibious vehicle, comprise torsionoscillation cylinder 1, lock plate 2, locking follower disk 3, torsion bar 4, lockable mechanism seat 5, locking buckle 6, pull back spring 7, bolt 8, nut 9.Described torsionoscillation cylinder 1 is bolted on vehicle frame with lockable mechanism seat 5.Described lock plate 2 is fixed on the rolling disc 10 of torsionoscillation cylinder 1 by socket bolt.Described locking follower disk 3 is pierced into by self bearing pin in the hole at lock plate 2 center, and the two is coaxial, but can relatively rotate.Described torsion bar 4 is coordinated with the spline housing of locking follower disk 3 by its termination spline to be installed.Described locking button 6 and pull back spring 7 by bolt 8 through being arranged in lockable mechanism seat 5, and locked by nut 9, under state of nature after assembling, locking button 6 is subject to the spring force of pull back spring 7 and outwardly, finally because the limit dais of self boss and lockable mechanism seat 5 is spacing and static, as shown in Figure 3.
As shown in Figure 1, described lock plate 2 is made into cams, and there is enough large hole centre to carry out radial location to locking follower disk 3; Have a circle counter sink outside hole, the diameter of the macropore of counter sink and the degree of depth need enough large, to put into suitable socket bolt, are fixed on the rolling disc 10 of described torsionoscillation cylinder 1 by this circle socket bolt by lock plate 2; Correct position between the boss and counter sink of described lock plate 2 cam, there is the alignment pin 11 that is outwardly, described alignment pin 11 is through the waist-shaped hole 12 of one section of arc on locking follower disk 3, when alignment pin 11 turns to the end of waist-shaped hole 12 and is rotated further, alignment pin 11 can drive locking follower disk 3 to rotate together.
As shown in Figure 1, described locking follower disk 3 rear portion is provided with circular bearing pin, and its bearing pin inserts in the macropore of lock plate 2, can carry out radial location to locking follower disk 3; Described locking follower disk 3 front portion is provided with spline housing, and its termination spline inserts so far in spline housing by torsion bar 4, and when described locking follower disk 3 rotates, drive torsion bar 4 rotates by spline housing together; Described locking follower disk 3 is provided with the waist-shaped hole 12 of one section of arc, and its pore diameter size just can make the alignment pin 11 of lock plate 2 pass.
As shown in Figure 1, described locking button 6 has certain thickness, and it can be divided into long-armed and galianconism, and long-armed, galianconism contacts with lock plate 2, locking follower disk 3 respectively, and there is the rounding of larger radian in the place of its contact; As shown in Figure 4, the right of described locking button 6 is spacing by the limit dais of lockable mechanism seat 5; As shown in Figure 2, when this torsion bar Locking Device locking, described lock plate 2 contacts with the long-armed of locking button 6, and locking follower disk 3 contacts with the galianconism of locking button 6.
As shown in Figure 3, a kind of torsion bar Locking Device lockup state utilizing torsion bar to overturn wheel of the present utility model is: locking follower disk 3 radial direction is located by lock plate 2, locking follower disk 3 downwards upset is spacing by the spacing sloping platform of lockable mechanism seat 5 lower end, locking follower disk 3 upwards overturns by locking button 6 spacing, because locking follower disk 3 to be achieved the locking of torsion bar by locking.
When a kind of amphibious vehicle utilizing torsion bar to overturn the torsion bar Locking Device of wheel of the present utility model travels in water, as shown in Figure 5, lock plate 2 left-hand revolution is driven by described torsionoscillation cylinder 1 left-hand revolution, it is inner that locking button 6 is pressed into lockable mechanism seat 5 by described lock plate 2 cam, and locking button 6 is away from locking follower disk 3; Because described locking follower disk 3 is provided with the waist-shaped hole 12 of one section of arc, in the certain angle of described lock plate 2 when initial rotation, its alignment pin 11 is trackslipped in the curved waist nibs 12 of described locking follower disk 3, does not drive locking follower disk 3 to rotate.As shown in Figure 6, described torsionoscillation cylinder 1 continues left-hand revolution, then lock plate 2 is driven to rotate, the now end of locking follower disk 3 curved waist the nibs 12 because alignment pin of lock plate 2 has been trackslipped, therefore locking follower disk 3 left-hand revolution together can be driven, and locking button 6 is now pushed to lockable mechanism seat 5 inside by the cam of lock plate 2 already, described locking button 6 no longer limits the rotation of locking follower disk 3, therefore torsion bar 4 and wheel will be reversed lifting smoothly and got up, now wheel is more than the water surface, greatly reduce the resistance that amphibious vehicle sails on the water.
When of the present utility model a kind of utilize torsion bar overturn wheel torsion bar Locking Device amphibious vehicle need by water in proceed to land locomotion time, this Locking Device initial condition as shown in Figure 6, described torsionoscillation cylinder 1 clickwise drives lock plate 2 clickwise, described lock plate 2 cam will away from locking button 6, locking button 6 pops up and touch the transition face of lock plate 2 cam under the effect of pull back spring 7, when described torsionoscillation cylinder 1 clickwise drives lock plate 2 cw to further rotate, and on lock plate 2 alignment pin 11 on rotary locking follower disk 3 waist-shaped hole 12 lower end after, oscillating cylinder 1, lock plate 2, locking follower disk 3 by synchronous clickwise until locking follower disk 3 is spacing by lockable mechanism seat 5 lower shoe, at this moment locking button 6 upsprings to vertex under the effect of pull back spring 7, its galianconism just in time withstands locking follower disk 3, as shown in Figure 3, at this moment above-mentioned of the present utility model a kind of torsion bar Locking Device lockup state utilizing torsion bar to overturn wheel is.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
