Abstract
The utility model discloses an anti-vibration castor. The utility model has the main technical characteristics that the anti-vibration castor comprises a fixed chassis and a fixed bracket which are connected together through a center shaft. The fixed bracket is fixedly provided with a prong with a wheel. A pressure plate is arranged on the position corresponding to the support plate on the prong. The support plate and the pressure plate are connected with each other through an elastic mechanism. The elastic mechanism comprises a first elastic mechanism with larger elastic coefficient and a second elastic mechanism with smaller elastic coefficient. One end of the second elastic mechanism is fixed on the support plate, and the other end has a certain distance from the pressure plate. The anti-vibration castor has good damping effect under different conditions such as empty vehicle, light load or heavy load and so on.
Description
Technical field
The utility model relates to a kind of castor, relates in particular to a kind of Shockproof castor.
Background technology
Along with industrial expansion, the application of wheel flutter with shock-absorbing function is more and more wider, at present, the Shockproof castor that uses adopts the fork that fixedly has wheel at the fixed mount axle, on fork, be provided with pressing plate with described supporting plate correspondence position, between supporting plate and described pressing plate, connect by elastic mechanism, elastic mechanism adopts the spring or the elastomer block of one or more identical elasticity moduluss, for the little elastic mechanism of elasticity modulus, during light or empty wagons, can play the effect of damping, when load-carrying vehicle when load-carrying vehicle is heavier, elastic mechanism all is crushed, and does not just have damping effect; Equally, if use the big elastic mechanism of elasticity modulus instead, during light or empty wagons, can not play the effect of damping when load-carrying vehicle.
The utility model content
The technical matters that the utility model solves just provide a kind of at empty wagons, carry car and can both play strong damping effect and long service life, use easy to operate a kind of Shockproof castor.
For solving the problems of the technologies described above, the technical scheme that a kind of Shockproof castor of the utility model adopts is: comprise the fixed underpan that links together by axis, fixed mount, the fork that fixedly has wheel at described fixed mount axle, on described fork, be provided with pressing plate with described supporting plate correspondence position, between described supporting plate and described pressing plate, connect by elastic mechanism, described elastic mechanism comprises first elastic mechanism and the second less elastic mechanism of elasticity modulus that elasticity modulus is bigger, described second elastic mechanism, one end is fixed on the described supporting plate, and the described pressing plate of other end distance has certain distance.
Its additional technical feature is:
Described first elastic mechanism is a spring, and described second elastic mechanism is an elastomer block;
The free end and the first elastic mechanism correspondence position in described elastomer block are provided with spring eye, and described first elastic mechanism inserts in the described spring eye;
Described first elastic mechanism is a spring, and described second elastic mechanism is the spring that is placed on described first elastic mechanism;
Described elastic mechanism also comprises the 3rd elastic mechanism that the elasticity modulus and first elastic mechanism are different with second elastic mechanism;
Described fixed mount is provided with the spacing catch of fork.
A kind of Shockproof castor provided by the utility model compared with prior art, have the following advantages: one, owing to comprise the fixed underpan that links together by axis, fixed mount, axle fixedly has the fork of wheel on described fixed mount, on described fork, be provided with pressing plate with described supporting plate correspondence position, between described supporting plate and described pressing plate, connect by elastic mechanism, described elastic mechanism comprises first elastic mechanism and the second less elastic mechanism of elasticity modulus that elasticity modulus is bigger, described second elastic mechanism, one end is fixed on the described pressing plate, the described supporting plate of other end distance has certain distance, when load-carrying vehicle during light or empty wagons, first elastic mechanism that elasticity modulus is big works, at this moment, the effect of damping is better, when load-carrying vehicle was heavier, second elastic mechanism that elasticity modulus is little worked, and plays good damping effect equally; Its two because described first elastic mechanism is spring, described second elastic mechanism is the spring that is placed on described first elastic mechanism, processes convenient; They are three years old, because described first elastic mechanism is a spring, described second elastic mechanism is an elastomer block, and the free end and the first elastic mechanism correspondence position in described elastomer block are provided with spring eye, described first elastic mechanism inserts in the described spring eye, increase the integrated carrying ability, increased damping effect; Its four because described elastic mechanism also comprises the 3rd elastic mechanism that the elasticity modulus and first elastic mechanism are different with second elastic mechanism, increased damping effect more; Its five because described fixed mount is provided with the spacing catch of fork, both prevented that the fork position from moving, prevented again because of the car body preponderance, damage first elastic mechanism and second elastic mechanism by pressure.
Description of drawings
Fig. 1 is the structural representation of a kind of Shockproof castor of the utility model;
Fig. 2 is the structural representation of a kind of damping of the utility model;
Fig. 3 is the structural representation of second kind of damping;
Fig. 4 is the structural representation of the third damping.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing a kind of Shockproof castor of the utility model.
As depicted in figs. 1 and 2, a kind of Shockproof castor of the utility model comprises fixed underpan 1 and is provided with the fixed mount 4 that has supporting plate 41, axle fixedly has the fork 6 of axletree 5 on fixed mount 4, on axletree 5, have wheel 7, correspondence position with supporting plate 41 on fork 6 is provided with pressing plate 61, below pressing plate 61, be fixed with the first bigger elastic mechanism 81 of elasticity modulus, free end at less second elastic mechanism, 82, the second elastic mechanisms 82 of the flexible coefficient of supporting plate 41 upper fixed has certain distance apart from pressing plate 61.Like this, during light or empty wagons, first elastic mechanism 81 that elasticity modulus is big works when load-carrying vehicle, and at this moment, the effect of damping is better, and when load-carrying vehicle was heavier, second elastic mechanism 82 that elasticity modulus is little worked, and plays good damping effect equally.
As shown in Figure 2, first elastic mechanism 81 can be spring, second elastic mechanism 82 is an elastomer block, first elastic mechanism 81 can directly be connected with elastomer block 82, also can be provided with spring eye 84, the first elastic mechanisms 81 at the free end of elastomer block 82 and first elastic mechanism, 81 correspondence positions heads in the spring eye 84.
For easy to process, as shown in Figure 3, first elastic mechanism 81 can be spring, and second elastic mechanism 82 is for being placed in the spring on described first elastic mechanism 81.
As shown in Figure 4, in order further to improve damping effect, also comprise the 3rd elastic mechanism 83 that elasticity modulus and first elastic mechanism 81 are different with second elastic mechanism 82.
In order to prevent that the fork position from moving, and because of the car body preponderance, damage first elastic mechanism 81 and second elastic mechanism 82 by pressure, fixed mount 4 is provided with the spacing catch 42 of fork.
A kind of Shockproof castor that the utility model provides can be wheel flutter, also can be directional wheel, as long as elastic mechanism is two or more elastic mechanism, all drops on the scope of the utility model protection.
