Abstract
A rubber spring damper is a rubber spring device which can perform a spacing function besides a vibration isolation function. The rubber spring damper is composed of a lower rubber spring (1), an upper rubber spring (2), an upper spacer (3), nuts (4), screw bolts (5), an upper connection seat (6), a lower connection seat (8), a lower spacer (7) and a gasket (11), wherein the lower rubber spring (1) is arranged in the lower connection seat (8); the upper rubber spring (2) is arranged in the upper connection seat (6); the upper spacer (3) is positioned on the upper side of the upper rubber spring (2); the lower spacer (7) is positioned on the lower side of the lower rubber spring (1); screw bolts penetrate through the upper spacer, the upper rubber spring, the upper connection seat, the lower rubber spring, the lower spacer, the lower connection seat and the gasket, and a rubber spring device is formed by fixing both ends of each screw bolt by nuts. The present invention has the advantages of simple structure, small size, low production cost and low running and maintenance expenses.
Description
Technical field
The present invention relates to a kind of rubber spring-loaded device that is applied to the engineering vehicle rubber suspension, belong to the technical field of suspension device for vehicle.
Background technique
Engineering vehicle uses in infrastructure construction, oil exploration, mining and various engineering in a large number as important launch vehicle, be indispensable means of transportation in the national economy activity of countries in the world, the quality of its suspension system performance directly influences the aspects such as working life, productivity and maintenance cost of vehicle driving smoothness, control stability, component.Very little for car load natural frequency under the different loads state that zero load extremely is fully loaded with is changed, thus keep stablizing and good run smoothness, and the suspension system of engineering vehicle adopts the stiffness variable structure more.The major and minor leaf spring form of the normal employing of traditional variable-rate suspension mechanism.In recent years, rubber spring with nonlinear variable-stiffness characteristic has begun to be applied in the suspension system of engineering vehicle, this change rigidity rubber suspension have travelling comfort good, from heavy and light, advantage such as exempt to lubricate, passing ability is good and more and more be subjected to the attention of engineering vehicle manufacturer.Engineering vehicle can relax impact after adopting and becoming the rigidity rubber suspension significantly, and minimizing is jolted, thereby improves driver's working condition and improve the driving speed of a motor vehicle.
For a long time, except the suspension system of rail vehicle often adopts rubber spring to do the main spring of suspension, other vehicle is seldom made the main spring of suspension with rubber spring.The good nonlinear characteristics of rubber spring be the steel spring can't be obtained, it has good stiffness characteristics equally when amount of deflection is very big, distortion that under stretching or compressive load effect, is produced and the non-linear relation characteristic between the load, can guarantee that vehicle is when suffered load changes, the natural frequency of its body vibrations changes very little, thereby improves the smoothness of vehicle driving greatly.Rubber spring has wideer good isolation frequency scope than steel spring, and more in light weight than other type elastic element, be easy to make and cost low.The shape of rubber spring is unrestricted, and the rigidity of all directions can freely be selected as required.In addition, its internal damping is big, has the ability of self attenuation vibration, and optimum bears big impulsive load.Compare with pneumatic spring, hydro-pneumatic spring, its reliability is higher.Therefore, rubber spring has tangible advantage as the main spring of engineering vehicle suspension, has broad application prospects.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of rubber spring-loaded device that is used for engineering vehicle rubber suspension master spring, except having the vibration isolation effect, also can play position-limiting action.
Technological scheme: this rubber spring-loaded device of the present invention is by descending rubber spring, last rubber spring, Upper gasket, nut, bolt, last connection seat, second line of a couplet joint chair and lower levelling plate and packing ring to form; Wherein, following rubber spring is installed in the second line of a couplet joint chair, last rubber spring is installed in the connection seat, Upper gasket be positioned at rubber spring above, lower levelling plate be positioned at following rubber spring below, bolt passes Upper gasket in proper order, goes up rubber spring, goes up connection seat, rubber spring, lower levelling plate, second line of a couplet joint chair form rubber spring-loaded device by two of nut fixing bolt down.Last connection seat is fixed on the vehicle frame, second line of a couplet joint chair links by dunnage and car sedan-chair, packing ring and second line of a couplet joint chair are vacated a segment distance, when vehicle is subjected to uneven road surface excitation and when producing vibration in the process of moving, rubber spring alternately plays the vibration isolation effect up and down, also plays position-limiting action when vibration amplitude is big.
Beneficial effect: the present invention is owing to adopt the main spring of the rubber spring of special shape as suspension, the rigidity of this rubber spring can increase along with the increase of load, makes no matter it is can both good riding comfort is provided and handle stationarity for vehicle under zero load or full load condition.2 rubber springs are connected by unique mode simultaneously, make it can play position-limiting action again.In addition, the utility model is simple in structure, volume is small and exquisite, cost of production is low, the operating maintenance expense is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: following rubber spring 1, last rubber spring 2, Upper gasket 3, nut 4, bolt 5, last connection seat 6, lower levelling plate 7, second line of a couplet joint chair 8, dunnage 9, car sedan-chair 10, packing ring 11.
Embodiment
Structure of the present invention as shown in drawings, this rubber spring-loaded device by following rubber spring 1, go up rubber spring 2, Upper gasket 3, nut 4, bolt 5, go up connection seat 6, second line of a couplet joint chair 8 and lower levelling plate 7 and packing ring 11 is formed; Wherein, following rubber spring 1 is installed in the second line of a couplet joint chair 8, last rubber spring 2 is installed in the connection seat 6, Upper gasket 3 be positioned at rubber spring 2 above, lower levelling plate 7 be positioned at following rubber spring 1 below, bolt 5 passes Upper gasket 2, goes up rubber spring 2, goes up connection seat 6, rubber spring 1, lower levelling plate 7, second line of a couplet joint chair 8 form rubber spring-loaded device by two of nut 4 fixing bolts 5 down.The bottom of second line of a couplet joint chair 8 is fixed in dunnage 9, the car sedan-chair 10, and packing ring 11 is vacated a segment distance with second line of a couplet joint chair 8, and in the suspension compresses stroke, the rubber spring of bottom is subjected to the compression of connection seat 6 and works; In the suspension extension stroke, packing ring 11 contacts with second line of a couplet joint chair 8, and the rubber spring on top is subjected to the pressure of pad 3 and is compressed, and range is subjected to the restriction of bolt 4 simultaneously.
