Abstract
The utility model discloses an elastic damping device for a running system of a dozer, which belongs to the technical field of an elastic damping device of a running system of a crawler dozer. Parts used for installing thrust wheels of a dozer are provided with two-stage swinging racks, the two-stage swinging racks swing around shafts of the two-stage swinging racks according to the state of the ground, and the thrust wheels contact a rail chain all the time; the elastic damping device is arranged between an upper surface of one end of a big swinging rack and a surface corresponding to a trolley; the elastic damping device comprises a supporting plate and a hollow rubber block; the bottom part of the hollow rubber block is connected with the supporting plate in a vulcanization adhering way. In the elastic damping device for a running system of a dozer of the utility model, the elastic damping device can be extruded and deformed through the motion of the swinging racks; the friction of motion among internal molecules can be caused by the self deformation of the device, and impact energy can be converted into heat energy to emit out; thus, the purposes of vibration damping and vibration isolation of the complete machine can be reached.
Description
Technical field
The utility model relates to a kind of vibration absorber, particularly a kind of elastic vibration clamper of crawler dozer running gear.
Background technology
The thrust wheel and the bogie frame of tradition bulldozer running gear pass through bolt, pin is realized rigid connection, impact from ground is passed on the chassis body by thrust wheel, simultaneously because the ground injustice, or during the bulldozer throwing over barrier, the rigid table vehicle frame can not guarantee that all thrust wheels all contact with ground, the weight of machine must be born by indivedual thrust wheels so, a certain thrust wheel is stressed to be the several times of its average and make from the reaction force on ground, even more than ten times situation, its walking mechanism easily produces violent vibration and impact, and this phenomenon is outstanding further with the increasing of bulldozer type.
The utility model content
At the shortcoming that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of in order to overcome crawler dozer running gear thrust wheel unbalance stress, and walking mechanism easily produces high vibration and impacts the elastic vibration clamper of the bulldozer running gear of this shortcoming.
In order to solve the problems of the technologies described above, elastic vibration clamper according to a kind of bulldozer running gear provided by the utility model, in the thrust wheel installation position two-stage rocker is set, the two-stage rocker is swung around its axle according to state of ground, thrust wheel is cheated to be contacted with the rail chain end, described elastic vibration clamper is arranged between corresponding of an end upper surface of big rocker and the chassis, play on the one hand big rocker swing position-limiting action, the elastic deformation by self elastic vibration clamper absorbs the shock loading from ground on the other hand; Described elastic vibration clamper comprises fagging and hollow rubber piece, and the bottom of hollow rubber piece is connected with fagging by the sulfuration adhering method; Described hollow rubber piece by the crown structure of dome have dome shaped outer surface the upper top branch, have the mid portion of outward-dipping annular outer wall and be the cylindric lower bottom part of an external surface and a basal surface that comprises and be grouped into, the horizontal section of each part is circular configuration; The basal surface of the part of going to the bottom is connected with fagging by the sulfuration adhering method; Mid portion is frustum when the rubber damping piece deforms coniform.
The elastic vibration clamper of the bulldozer running gear that the utility model provides, mainly be to make the passive generation crimp of elastic vibration clamper by the rocker motion, cause friction of motion between the interior molecules by this device self-deformation, impact energy is converted into heat energy to be dissipated to reach the complete machine vibration damping, the purpose of vibration isolation.

The specific embodiment
Below in conjunction with description of drawings enforcement of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
Extremely shown in Figure 4 referring to Fig. 1, the elastic vibration clamper of a kind of bulldozer running gear that present embodiment is described, in order to achieve the above object, in the thrust wheel installation position two-stage rocker is set, the two-stage rocker is swung around its axle according to state of ground, thrust wheel is cheated to be contacted with the rail chain end, described elastic damping element is arranged between 4 corresponding in an end upper surface of big rocker 3 and the chassis, play on the one hand big rocker 3 swing position-limiting actions, the elastic deformation by self elastic damping element absorbs the shock loading from ground on the other hand.Its structure is: described elastic vibration clamper comprises fagging 11 and hollow rubber piece 12, mainly bonding the forming of sulfuration of the fagging of being made by steel plate by 12 pairs of hollow rubber pieces 11.The structure of hollow rubber piece 12 mainly is made up of upper, middle, and lower part: the horizontal section of each part is circular configuration.Upper top divides A to be generally the crown structure of dome, has dome shaped outer surface.Mid portion B has outward-dipping annular outer wall, and it is coniform to be frustum when the rubber damping piece deforms, and the portion C of going to the bottom is cylindric, comprises an external surface and a basal surface, and basal surface is connected with fagging by the sulfuration adhering method.As shown in Figure 1 and Figure 2, when rocker is swung, flexible member 1,2 contacts among the figure, crimp, cause friction of motion between the interior molecules by self-deformation, the interior friction energy that most of impact energy is converted into flexible member consumes, and plays vibration isolation, vibration damping purpose.
In addition, on the basis of the foregoing description, to one of ordinary skill in the art, the utility model still can be done many variations.
Claims (3)
1, a kind of elastic vibration clamper of bulldozer running gear, it is characterized in that, this device is arranged between corresponding of an end upper surface of big rocker and the chassis, and described elastic vibration clamper comprises fagging and hollow rubber piece, and the bottom of hollow rubber piece is connected with fagging by the sulfuration adhering method.
2, the elastic vibration clamper of bulldozer running gear according to claim 1, it is characterized in that, described hollow rubber piece by the crown structure of dome have dome shaped outer surface the upper top branch, have the mid portion of outward-dipping annular outer wall and be the cylindric lower bottom part of an external surface and a basal surface that comprises and be grouped into, the horizontal section of each part is circular configuration; The basal surface of the part of going to the bottom is connected with fagging by the sulfuration adhering method; Mid portion is frustum when the rubber damping piece deforms coniform.
