Abstract

A kind of compartment damping rubber pad, between compartment and chassis, including with the matched upper plate in compartment, and the matched lower plate of chassis and buffer layer between the upper and lower plates is set；Both ends are equipped with upper limit item on the upside of the upper plate, are provided with limiting slot in positive stop strip stage casing, trapezoidal buffer part is equipped on the downside of upper plate；Both ends are equipped with lower limit item on the downside of lower plate；The upper limit item and/or lower limit section are right-angled trapezium；Lower plate is equipped with and the matched bolt hole of chassis between two lower limit items.The utility model structure positioning is accurate, can provide reliable support in the crank timing or shaking in compartment.If buffer layer in such a way that dry rubber substance hexagonal prisms are combined, than the bearing capacity that the rubber bodies of integral structure have bigger, provides better elastic buffer.The utility model structure have it is simple in structure, at low cost, bearing capacity is strong, and the good advantage of cushion performance can be widely used for the compartment damping of train.

Description

A kind of compartment damping rubber pad

Technical field

The utility model belongs to train parts technical field, is related to a kind of compartment damping rubber pad.

Background technology

Train in the process of moving, due to rail seam or other situations, will produce larger vibrations, be brought not to seating Comfortable to feel, especially to lorry, larger vibrations are likely to affect transporting safely for cargo.Therefore, usual train vehicle The rubber cushion for reducing vibrations is equipped between compartment and chassis, existing rubber cushion bearing capacity is smaller or is not well positioned to meet damping Requirement or need be arranged many places, it is very inconvenient.

Invention content

The purpose of this utility model is to provide a kind of compartment damping rubber pad, can provide larger bearing capacity, have Good damping effect, to solve the problems of the prior art.

The utility model is achieved by the following technical solution：A kind of compartment damping rubber pad is used for compartment Between chassis, it is characterised in that：Including with the matched upper plate in compartment, with the matched lower plate of chassis and setting in upper plate and Buffer layer between lower plate；

Both ends are equipped with upper limit item on the upside of the upper plate, are provided with limiting slot in positive stop strip stage casing, are equipped on the downside of upper plate trapezoidal Buffer part；Both ends are equipped with lower limit item on the downside of lower plate；The upper limit item and/or lower limit section are right-angled trapezium；Lower plate It is equipped with and the matched bolt hole of chassis between two lower limit items.

Further：If the buffer layer includes dry rubber substance hexagonal prisms, coating is equipped on the outside of rubber hexagonal prisms.

Further：Skid resistant course is equipped on the outside of the upper plate and lower plate.

The utility model has the beneficial effects that：The utility model structure positioning is accurate, can be relatively horizontal to avoid damping rubber pad Beam length direction vibration.It is integrally formed with trapezoidal buffer part on the downside of upper plate, can be carried in the crank timing or shaking in compartment For reliably supporting.It is additionally provided with mutually matched location hole on upper plate and lower plate, positions and uses when with the vulcanization of rubber, so that respectively Partial position is relatively accurate.If buffer layer, in such a way that dry rubber substance hexagonal prisms are combined, the rubber bodies than integral structure have The bearing capacity for having bigger provides better elastic buffer.The utility model structure has simple in structure, at low cost, carrying energy Power is strong, and the good advantage of cushion performance can be widely used for the compartment damping of train.

Description of the drawings

Fig. 1 is the overall structure diagram of the utility model；

Fig. 2 is the sectional view of Fig. 1.

Number explanation in figure：1 is upper plate, and 11 be upper limit item, and 12 be limiting slot, and 13 be buffer part, and 2 be lower plate, and 21 are Lower limit item, 22 be bolt hole, and 3 be buffer layer, and 4 be location hole.

Specific implementation mode

Be a kind of compartment damping rubber pad of the utility model structure as shown in Figs. 1-2, for compartment and chassis it Between, four corners are normally placed at, the vibrations for reducing compartment.Including with the matched upper plate 1 in compartment, it is matched with chassis The buffer layer 3 of lower plate 2 and setting between the upper and lower plates；

Both ends are equipped with upper limit item 11 on the upside of the upper plate, and upper limit item is matched with the crossbeam on carriage frame, prevented Displacement is generated between compartment and damping rubber pad, limiting slot 12 is provided in positive stop strip stage casing, and longitudinal direction can be carried out at limiting slot It is fixed, typically it is spirally connected a bolt in the position of limiting slot in crossbeam, it can be to avoid damping rubber pad with respect to crossbeam length direction Vibration.It is integrally formed with trapezoidal buffer part 13 on the downside of upper plate；Trapezoidal buffer part can be in the crank timing or shaking in compartment Reliable support is provided, when slight shift occurs such as center of gravity, upper plate is slightly slanted, such as when tilting to the left, at this point, left side Rubber part deflection is larger, right side it is relatively small, that is, by rubber elasticity offset a part of strength, to prevent down Plate fall off from chassis or between be subjected to displacement, lower plate between two lower limit items be equipped with and the matched bolt hole of chassis 22, lower plate and chassis can be made to be spirally connected fixation, to increase its safety.Mutually matched positioning is additionally provided on upper plate and lower plate Hole 4 positions when with the vulcanization of rubber and uses, so that the position of each section is relatively accurate.

Both ends are equipped with lower limit item 21 on the downside of lower plate；The upper limit item and/or lower limit section are right-angled trapezium, should The setting of shape can provide maximum limit strength.

Preferably：If the buffer layer includes dry rubber substance hexagonal prisms, coating 32, institute are equipped in 31 outside of rubber hexagonal prisms State coating as a shell by rubber hexagonal prisms tightly be bundled together to form a honeycomb, honeycomb Rubber bodies have the bearing capacity of bigger than the rubber bodies of integral structure, provide better elastic buffer.

Preferably：Skid resistant course is equipped on the outside of the upper plate and lower plate, the skid resistant course is rubber layer, is on the one hand increased Adhesive force between compartment and chassis, while also making that this structure is wear-resisting, antiseptic property increases.

To sum up, the utility model structure has simple in structure, and at low cost, bearing capacity is strong, the good advantage of cushion performance, can It is widely used in the compartment damping of train.
