Abstract
The utility model relates to an engineering vehicle engine buffering fulcrum bearing which solves the problem that an engine can be damaged due to the fact that an ordinary rigid connection is adopted on the engine bearing. The engineering vehicle engine buffering bearing comprises a trunnion, a fulcrum bearing seat, an upper elastic end sleeve, a lower elastic end sleeve, an elastic outer ring, an elastic inner ring, a trunnion inner end fulcrum bearing cushion and a trunnion outer end fulcrum bearing cushion, wherein the trunnion inner end fulcrum bearing cushion, the upper elastic end sleeve, the elastic outer ring, the elastic inner ring and the lower elastic end sleeve are sequentially installed between a trunnion body and the fulcrum bearing seat from the inner end of the trunnion to the outer end of the trunnion. The trunnion outer end fulcrum bearing cushion is pressed on the outer end surfaces of the lower elastic end sleeve and the trunnion body, and the trunnion outer end fulcrum bearing cushion and the trunnion body are connected in a fastening mode through bolts, wherein the structures of the upper elastic end sleeve and the lower elastic end sleeve are the same and are formed by a manner that inner metal rings and outer metal rings are glued through elastic sizing materials, the elastic inner ring and the elastic outer ring are glued by the metal rings and the sizing materials, the elastic outer ring is arranged on the elastic inner ring in a sleeved mode, and sizing material parts are opposite. The engineering vehicle engine buffering fulcrum bearing is simple in structure and convenient to install.
Description
Technical field:
The utility model relates to a kind of stand arrangement of engineering truck, particularly a kind of engineering vehicle engine buffering supporting.
Background technology:
Existing engineering truck such as crawler doer, pile driver or development machine etc. are when walking and operation, the high engine speeds rotation (turns scooter 1200～2000r/min), engine crankshaft, connecting rod and piston etc. all act under the reverse stress of circulation, the vibration that brings needs to be delivered to frame by engine mounting, and frame also can produce self-vibration owing to walking and working, therefore at present can lose efficacy because of chronic fatigue when engine mounting adopts common being rigidly connected, finally the normal operation of driving engine can be affected, driving engine can be damaged when serious.
Summary of the invention:
The supporting of the utility model buffering adopts the acting of elastic element buffering to eliminate engine vibration; avoid supporting fatigue failure; thereby play the effect that reduces noise, protection driving engine, eliminates the potential safety hazard of driving engine, solved engine mounting and adopted common being rigidly connected to damage the problem of driving engine.
The utility model is achieved through the following technical solutions:
the supporting of a kind of engineering vehicle engine buffering, comprise gudgeon, supporting base, upper elastic tip cover, lower elastic tip cover, elastic housing washer, the elasticity inner ring, the inner support pads of gudgeon and gudgeon outer end support pads, the inner support pads of gudgeon, upper elastic tip cover, elastic housing washer, elasticity inner ring and lower elastic tip cover are assemblied between gudgeon axis body and supporting base from gudgeon the inner outward successively, gudgeon outer end support pads is pressed on the outer face of lower elastic tip cover and gudgeon axis body and with bolt, gudgeon outer end support pads and gudgeon axis body is fastenedly connected, wherein go up the elastic tip cover, lower elastic tip nested structure is identical, by elastic glue material with in metal, outer ring formation glued together, elasticity inner ring and elastic housing washer form by wire loop and sizing material gummed, elastic housing washer is enclosed within on the elasticity inner ring, the sizing material part relatively.
On the gudgeon axis body of the inner support pads of gudgeon the inner, adjusting pad is installed, adjusting pad is the socket type metallic gasket.
The utility model also can be used for other power system or driving device of requiring vibration damping or eliminating the reverse stress impact.Have simple in structure, easy for installation, buffer shock-absorbing and reduce the function of noise.
Description of drawings:
Fig. 1 is the integral structure schematic diagram of the utility model;
Fig. 2 is the upper and lower elastic tip cover schematic diagram of the utility model;
Fig. 3 is the elasticity inner ring schematic diagram of the utility model;
Fig. 4 is the elastic housing washer schematic diagram of the utility model;
Fig. 5 is the adjusting pad schematic diagram of the utility model.
The specific embodiment:
As shown in Figure 1, this device is comprised of the inner support pads 3 of gudgeon 1, adjusting pad 2, gudgeon, upper elastic tip cover 4, lower elastic tip cover 4 ', supporting base 5, elastic housing washer 6, elasticity inner ring 7, bolt 8, gudgeon outer end support pads 9.Concrete array mode is as follows: adjusting pad 2, the inner support pads 3 of gudgeon, upper elastic tip cover 4, elasticity inner ring 7, elastic housing washer 6, supporting base 5, lower elastic tip cover 4 ' are assemblied on gudgeon 1 axis body successively, gudgeon outer end support pads 9 and fixing with bolt 8 is installed at last
Form an elastic support; Adjusting pad 2 is used for adjusting the installation dimension of driving engine.This device is installed between driving engine and frame, carries out the first-level buffer vibration damping by two elastic tip covers, elastic housing washer 6 and elasticity inner ring 7 carry out the level 2 buffering vibration damping.
As shown in Figure 2, upper and lower elastic tip cover 4 is glued together with metal inner ring 11 and metal outer ring 12 by elastic glue material 10, forms an elastic element.
As shown in Figure 3, Figure 4, elasticity inner ring 7 and elastic housing washer 6 form a kind of elastic element by wire loop 13 and sizing material 14 gummeds, and the sizing material 14 of its Elastic inner ring 7 is positioned at the outside, and the sizing material 14 of elastic housing washer 6 is positioned at the inboard.
As shown in Figure 5, adjusting pad 2 is the socket type metallic gasket, is convenient to dismounting.
The utility model is that gudgeon and supporting base are assembled into a kind of shock absorber by elastic part, driving engine is connected with vehicle frame by this device, support to eliminate the vibration stress of driving engine by buffering when guaranteeing installation dimension, can play the function of buffering, vibration damping.Not only can guarantee the normal operation of driving engine but also can reach the function that extends engine life.
