Description
Technical field
The utility model relates to the lockable mechanism in a kind of AE field, specifically is a kind of rail dual-purpose vehicle steel spring lockable mechanism.
Background technology
The rail dual-purpose vehicle is in being transformed into the rail running process, require the axle positioning of road running to be higher than track, but the steel spring suspension that highway uses is subjected to the effect of vehicle bridge deadweight, make the steel spring resilience even be in extended state, this can influence ride comfort and the crossing ability of vehicle at rail running.Therefore, need carry out spacing locking to steel spring.
At present, the oleo-pneumatic suspension system can realize the latch functions of vehicle, but it can't adopt current widely used steel spring as suspension system.Chinese patent literature number: CN2871265Y discloses a kind of " resilient suspension rigidity lockable mechanism ", and it can form suspension system, applied range in conjunction with multiple elastic element.But it is designed when it just is in the low speed operation at engineering truck, vehicle bridge still directly contacts with ground by wheel during its lockup state, consider the influence of vehicle bridge deadweight, this patent can not satisfy the requirement that rail vehicle axle positioning when rail running is higher than track, and it adopts spline and pull rope mechanism structure more complicated, manufacturing, assembly precision require high, and maintenance is inconvenient.
Summary of the invention
The utility model proposes a kind of rail dual-purpose vehicle steel spring lockable mechanism at the deficiencies in the prior art, and this mechanism structure is simple, working stability, easy to maintenance, satisfy the driving cycle of rail dual-purpose vehicle, and can regulate the springback capacity of steel spring according to the specific requirement of vehicle.
The utility model is achieved through the following technical solutions, and the utility model comprises: movable component and the corresponding matable assembly that is provided with, when movable component matched with matable assembly, this mechanism was in lockup state.
Described movable component comprises: action tank, thread rod and locking hitch, and wherein: action tank and thread rod are all hinged with vehicle, and thread rod and locking hitch flexibly connect, and action tank is connected with the locking hitch.
Described thread rod and locking hitch adopt screw thread pair to flexibly connect, and by the rotation of locking hitch, regulate the locking hitch in the upper and lower position of thread rod, thereby can control the springback capacity of steel spring.
Described matable assembly comprises: steel spring cover plate, steel spring and spring clip, wherein: the steel spring cover plate is captiveed joint with steel spring by spring clip.
Described steel spring cover plate center is provided with the cantilever cylinder, and when the locking hitch of movable component matched with the cantilever cylinder, this mechanism was in lockup state.The position of restriction cantilever cylinder is exactly the position of having limited steel spring.
When the rail vehicle travels on highway, the cylinder rod of action tank shrinks, the action tank band the hinge-point clickwise of locking hitch around thread rod, make the locking hitch leave the cantilever cylinder of spring bumper cover, at this moment steel spring can not be subjected to the influence of locking structure, lockable mechanism is in released state, and this moment, the rail dual-purpose vehicle can guarantee the traveling comfort and the ride comfort of road running.When the rail vehicle travels in orbit, the cylinder rod elongation of action tank, with locking hitch left-hand revolution under the cantilever cylinder of spring bumper cover, by of the effect of locking hitch to the cantilever cylinder of spring bumper cover, can limit the resilience of steel spring, this mechanism is in lockup state, has prevented the whereabouts of vehicle vehicle bridge in rail running like this, can guarantee rail vehicle travelling comfort in orbit.
The utility model is realized the locking to the resilience that resets of steel spring by the control to action tank.With respect to the lockable mechanism with stay cord, that this example has is simple in structure, reliable operation, characteristics easy to maintenance, and can regulate the springback capacity of steel spring according to the specific requirement of vehicle.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment comprises: movable component 1 and the corresponding matable assembly 2 that is provided with, wherein: when movable component 1 matched with matable assembly 2, this mechanism was in lockup state.
Described movable component 1 comprises: action tank 3, thread rod 4 and locking hitch 5, and wherein: action tank 3 and thread rod 4 are all hinged with vehicle 6, and thread rod 4 flexibly connects with locking hitch 5, and action tank 3 is connected with locking hitch 5.
Described thread rod 4 adopts screw thread pair to flexibly connect with locking hitch 5, by the rotation of locking hitch 5, regulates locking hitch 5 in the upper and lower position of thread rod 4, thereby can control the springback capacity of steel spring 8.
Described matable assembly 2 comprises: steel spring cover plate 7, steel spring 8 and spring clip 9, wherein: steel spring cover plate 7 is captiveed joint with steel spring 8 by spring clip 9.
Described steel spring cover plate 7 centers are provided with cantilever cylinder 10, and when the locking hitch 5 of movable component 1 matched with cantilever cylinder 10, this mechanism was in lockup state.The position of restriction cantilever cylinder 10 is exactly the position of having limited steel spring 8.
As shown in Figure 1, when the rail vehicle travelled on highway, action tank 3 shrank, and at this moment lockable mechanism is in released state, and steel spring 8 is not influenced by the spacing of this mechanism.
As shown in Figure 2, when the rail vehicle travelled in orbit, action tank 3 elongations rotated to locking hitch 5 under the cantilever cylinder 10 of steel spring cover plate 7, can limit the resilience of steel spring 8 by the effect of locking hitch 5 and cantilever cylinder 10, realize the locking of suspension.
The utlity model has simple in structure, cost is low, the life-span is long, reliable operation, characteristics easy to maintenance.
