Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As documented by background technique, it is some in the prior art, it is steel that actuating plunger device can be integrated in two
It is in parallel therewith inside spring.When actuator locking, even if upper and lower passenger, steel spring will not vibrate, but ought transport on the line
When row, it is filled with hydraulic oil inside actuator, certain damping force can be generated, setting so often influences whether secondary spring
Normal damping effect.
To solve the above-mentioned problems, referring to shown in Fig. 1 to Fig. 3, the present invention provides a kind of train height adjustment device,
In, which includes compartment, the bogie that car bottom is arranged in, the bolster and framework being arranged on bogie, and setting exists
Secondary suspension system between the bolster and the framework, the train height adjustment device include actuating plunger, actuating plunger
It is arranged in inside the secondary spring 10 of secondary suspension system, actuating plunger includes having the piston cylinder 20 of inner cavity and being threaded through piston
Piston rod 30 in cylinder 20, the top of piston cylinder 20 and the bolster of car bottom connect, and the first end of piston rod 30 is movably
It is threaded through in piston cylinder 20, the first end of piston rod 30 is provided with stop lug 31, and the second end of piston rod 30 is connect with framework；
Actuating plunger further includes piston pad 40, and piston pad 40 is movably disposed in inner cavity, and inner cavity is divided into epicoele 21 and cavity of resorption
22, piston rod 30 is movably threaded through in piston pad 40, and piston pad 40, which has, resists the adjusting position of stop lug 31, and and
The isolated evacuation position of stop lug 31, fills hydraulic oil into cavity of resorption 22, and piston pad 40 can be made to switch to from evacuation position
Adjusting position, and then make 30 retraction inner cavity of piston rod, reduce compartment.Since train height adjustment device of the invention includes making
Piston, actuating plunger include piston rod and the piston pad separately positioned with piston rod, are not needing actuating plunger to compartment
When height is adjusted, the stop lug and piston pad of piston rod are separated from each other evacuation, and the hydraulic oil in inner cavity is formed
Resistance very little, do not interfere with the normal damping effect of secondary spring, make passenger during seating have it is good relax
