Description
Technical field
The invention provides a kind of buffer structure, specifically relate to a kind of energy disperser that can the adjustable elastic modulus, belong to buffering equipment technology field.
Background technology
Coupling device at car end refers to and connects between two vehicles or connect all machineries, air and the electric apparatus between two car teams.Comprise shock absorber and electrical connection arrangement between hitch, energy disperser, windscreen, car body.The traction shock absorber is the vitals of locomotive, and its purposes is locomotive to be connected or to separate train with vehicle.The transmitting tractive that is in operation power or impulsive force, mitigation and decay train operation are because variation and the braking force inconsequent of tractive force cause shock and vibration.Therefore, it has the effect of connection, traction and buffering.Draw structure, performance and the state of shock absorber, affect to a great extent the running stability of train.The traction shock absorber is comprised of hitch, energy disperser and three parts of coupler centering device.
Generally can be divided into 1. spring friction draft gears, 2. rubber friction draft gear, 3. water bumper etc.
The performance perameter of energy disperser includes: (1) stroke: the maximum deformation quantity of the stressed lower generation of energy disperser is called stroke.Now, elastic element is in killing state, and when continuing to increase external force, deflection no longer increases.(2) maximum resistance: external force action when energy disperser reaches stroke.Impedance operator: the size of draft gear reaction force at rating travel and variation.(3) buffer capacity: energy disperser is when being subject to impacting, and in the full compression process, institute's work is called the capacity of energy disperser.(4) S. E. A.: energy disperser is in compression process, and some impact energy is damped to consume.The ratio that it consumes portion of energy and capacity, be called S. E. A..It shows the ability of apparatus with shock absorbing.Absorptivity is larger, and backwash is little, and impact process stops sooner.(5) resilient energy: the energy that energy disperser is emitted when restoring.(6) durability: energy disperser keeps the ability of its capacity in utilization.
But the modulus of elasticity of existing shock absorber is difficult for regulating, and therefore is not suitable for being applied to multiple occasion, and in addition, shock absorber also needs that extra insurance measure is arranged, after preventing that buffer unit from damaging, still there is certain cushion characteristic.
Summary of the invention
The objective of the invention is: the vehicle that provides a kind of modulus of elasticity to regulate articulates shock absorber, and can have additional insurance cushion characteristic.The technical scheme adopted is:
A kind of vehicle of adjustable elastic modulus articulates buffer structure, comprise that first articulates unit, second and articulate unit, also include wedge-shaped member, wedge-shaped member matches with the first groove articulated on unit, the other end of wedge-shaped member is movably connected on second and articulates unit, first articulates unit and second articulates between unit and is connected by the first elastomeric element, and wedge-shaped member articulates Shang position, unit second, and to adjust direction vertical with the elastic deformation direction of the first elastomeric element.
In use, articulate Shang position, unit by the adjustment wedge-shaped member second and just can control the mated condition of wedge-shaped member and groove, if when wedge-shaped member is put to outside adjusted position, first articulates unit and second, and to articulate the pressurized situation of the first elastomeric element between unit less, and modulus of elasticity can diminish; In like manner, if wedge-shaped member is inwardly adjusted to position, first articulate unit and second to articulate the pressurized situation of the first elastomeric element between unit larger, modulus of elasticity can become greatly, thereby can be adapted to different environments for use.
As the present invention, further improve, the wedge-shaped member middle part is provided with the second elastomeric element.While adopting such structure, to articulate the unit pressurized more when first, and the bearing capacity that the first elastomeric element provides has in limited time, wedge-shaped member will contact with the plane on groove top, this plane can produce pressure-acting to the second elastomeric element, elastic force by the second elastomeric element can provide buffering further, and then has made up the deficiency of the first elastomeric element.
As the present invention, further improve, first articulates on unit and is provided with the first slide bar, second, articulates on unit and is provided with the first slideway matched with the first slide bar.First articulates unit and second articulates unit and can move by slide bar and being connected mutually of slideway, keeps the stable of shock absorber.
Further improve as the present invention, on a side of the second elastomeric element on wedge-shaped member, the second slide bar is set, be provided with the second slideway matched with the second slide bar on opposite side.Also can make the pressurized motion of wedge-shaped member more stable.
beneficial effect
The present invention articulates unit by the employing wedge-shaped member to first and the second modulus of elasticity articulated between unit is adjusted, and can change easily two stress that articulate between unit.
