Abstract
The utility model relates to a new type engine vibration-absorbing device, which comprises a front vibration absorber and a rear vibration absorber. An upper connecting plate of the front vibration absorber and a fixing bracket of an engine are fixed with connecting screws. The lower connecting plate and the fixing bracket of the engine are fixed with connecting screws. A reinforced plate is arranged between the upper connecting plate and the lower connecting plate. A vibration absorbing rubber is arranged between the reinforced plate and the lower connecting plate. The fixing bracket of the engine, a guide bush, an adjusting spacer and a pressing plate are fixed together with a connecting bolt of the rear vibration absorber. The vibration absorbing rubber connecting to the fixing plate which is connected with the fixing bracket of the vehicle frame through a connecting bolt is arranged around the guide bush. The engine vibration-absorbing device has good vibration absorption effect, preventing from the influence caused by the engine's swing without any swinging to lower the vibrating transmission in work and the noise around, easy mounted, repaired and changed, widely used for most engineering vehicles.
Description
Technical field
The utility model relates to a kind of vibration damping equipment of engineering machinery engine.
Background technique
At present, the vibration damping form of the motor of engineering machinery generally is to add a rubber pad between motor fixed bearing and vehicle frame (car body) fixed bearing on the Domestic market, with fixing bolt two fixed bearings is coupled together by rubber pad then, and effectiveness in vibration suppression is bad; Also the front and back fixed form of the motor of some engineering machinery and vehicle frame (car body) all adopts Vertical direction structural type vibration damping, and this structure is big because of swinging of motor, is not easy control, and effectiveness in vibration suppression is bad.
Summary of the invention
The new work engine vibration damping equipment that the purpose of this utility model provides a kind of good damping result, is difficult for swinging.
The purpose of this utility model is achieved in that by preceding vibration damper and rear shock absorber to be formed, the upper junction plate and the motor fixed bearing of preceding vibration damper are fixed with connecting bolt, lower connecting plate and vehicle frame fixed bearing are fixed with connecting bolt, between upper junction plate and the lower connecting plate stiffening plate is arranged, between stiffening plate and the upper junction plate vibration isolation rubber is arranged, between stiffening plate and the lower connecting plate vibration isolation rubber is arranged; The connecting bolt of rear shock absorber passes motor fixed bearing, guide pin bushing, adjustment spacer ring and pressing plate and is fixed as one, and is vibration isolation rubber around the guide pin bushing, and vibration isolation rubber is connected and fixed plate, and fixed plate is connected with the vehicle frame fixed bearing by connecting bolt.
Because the utility model adopts said structure: this vibration damping equipment not only can play the effect of the vibration damping of motor, and, will play very big effect for the other noise of the ear that reduces the driver especially for Noise Control.Simultaneously can overcome the influence that is subjected to engine wobble effectively again.Transfer of vibration when reducing engine operation effectively reduces the other noise of driver's ear; Easy for installation, for ease of maintenaince, change; Each component is easy to processing; Physical dimension is little, is easy to arrange; Simultaneously, applicable to the various engineering vehicle.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.Fig. 2 is preceding damper structure figure of the present utility model.
Fig. 3 is a rear shock absorber structural drawing of the present utility model.Fig. 4 is the plan view of Fig. 3.
1 upper junction plate, 2 vibration isolation rubbers, 3 stiffening plates, 4 lower connecting plates, 5 guide pin bushings, 6 fixed plates, 7 are adjusted the distance between spacer ring, 8 pressing plates, 9 motor fixed bearings, 10 vehicle frame fixed bearings, 11 connecting bolts, 12 preceding vibration dampers, L motor front and back support among the figure.
Embodiment
Form by preceding vibration damper 12 and rear shock absorber, the upper junction plate 1 of preceding vibration damper 12 is fixing with motor fixed bearing 9 usefulness connecting bolts 11, lower connecting plate 4 is fixing with vehicle frame fixed bearing 10 usefulness connecting bolts 11, between upper junction plate 1 and the lower connecting plate 4 stiffening plate 3 is arranged, vibration isolation rubber 2 is arranged between stiffening plate and the upper junction plate, between stiffening plate 3 and the lower connecting plate 4 vibration isolation rubber 2 is arranged, connection rear engine body becomes elasticity with vehicle frame and is connected, the damping effect of vibration isolation rubber 2 can weaken the propagation of engine luggine greatly, during placement will with the angled α of horizontal plane, can prevent the solid failure (is fore-and-aft direction with reference to the engine crankshaft centerline direction) that swinging of motor produced like this, angle [alpha] can be regulated according to the stressing conditions of vehicle.The connecting bolt 11 of rear shock absorber passes motor fixed bearing 9, guide pin bushing 5, adjusts spacer ring 7 and pressing plate 8, around the guide pin bushing 7 is vibration isolation rubber 2, vibration isolation rubber 2 is connected and fixed plate 6, fixed plate 6 is connected with vehicle frame fixed bearing 10 by connecting bolt 11, during installation, guide pin bushing 5 contacts with the engine block rigidity, and fixed plate 6 directly is connected with vehicle frame (car body), guide pin bushing 5 then is connected by vibration isolation rubber 2 with fixed plate 6, and this structure plays effectiveness in vibration suppression effectively.For four point-supported motor fixed systems, in the motor rear and front end (along the crankshaft center direction) respectively with preceding vibration damper 12 and rear shock absorber with motor and vehicle frame link together (as Fig. 1), this vibration damping equipment can prevent the influence of engine luggine to vehicle effectively, can guarantee the constant intensity of motor again.
According to different configurations, adjust the big or small (see figure 1) of L in good time, then this vibration damping equipment can be applicable to various engineering vehicles.
