In an embodiment, described automobile chassis sealed mode hydraulic mount damping device, is characterized in that: comprise sealing shell, in sealing shell, baffle plate is set, main vibration damper is installed in the side of baffle plate, main vibration damper arranged outside counterdie, counterdie arranged outside drain pan; Arrange rubber spring at the opposite side of described baffle plate, arrange bolt bearing in rubber spring, the afterbody of bolt bearing and fixing bolt is fixed, and the head of fixing bolt stretches out sealing shell outside; At the external part sealing shell arranged outside rubber gasket of described fixing bolt.
Further, the sidepiece of described helical duct dividing plate arranges internal support, and bottom and the rubber spring of internal support are fixed.
Further, described main vibration damper comprises elasticity decoupler and helical duct dividing plate.
Further, described helical duct dividing plate has inertia channel.
The utility model can play good damping effect, by reducing various complex road condition and automobile engine compartment greasy dirt to the sealing exposing rubber on the impact in rubber life-span, improve device overall performance and life-span, and only need change base and just can realize various general, meet the requirement of automobile industry modularized production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: described automobile chassis sealed mode hydraulic mount damping device comprises fixing bolt 1, rubber gasket 2, bolt bearing 3, rubber spring 4, sealing shell 5, internal support 6, baffle plate 7, elasticity decoupler 8, helical duct dividing plate 9, counterdie 10, drain pan 11 etc.
As shown in Figure 1, the utility model comprises sealing shell 5, and sealing shell 5 is stamping part, formed by stamped, for the main vibration damper of closed protective, and sealing shell 5 according to each vehicle actual demand at shell external welding fixed support, can realize the requirement of modularized production; In described sealing shell 5, baffle plate 7 is set, baffle plate 7 is stamping part, formed by stamped, main vibration damper is installed in the side of baffle plate 7, and main vibration damper comprises elasticity decoupler 8 and helical duct dividing plate 9, helical duct dividing plate 9 arranged outside counterdie 10, counterdie 10 arranged outside drain pan 11, drain pan 11 is stamping part, is formed by stamped, does not damage protection internal main vibration damper for the protection of counterdie 10; Arrange rubber spring 4 at the opposite side of described baffle plate 7, arrange bolt bearing 3 in rubber spring 4, bolt bearing 3 is fixed with the afterbody of fixing bolt 1, and the head of fixing bolt 1 stretches out sealing shell 5 outside; At the external part sealing shell 5 arranged outside rubber gasket 2 of described fixing bolt 1, rubber gasket 2 adopts vulcanization of rubber part, is formed by the vulcanization of rubber.
The sidepiece of described helical duct dividing plate 9 arranges internal support 6, and bottom and the rubber spring 4 of internal support 6 are fixed, and internal support 6 is stamping part, is formed by stamped, for being fixed in sealing shell 5 by main vibration damper.
Described fixing bolt 1 is machined piece, by forging and pressing rear machining manufacture, for fixing with motor.
Described bolt bearing 3 is working of plastics, is manufactured by injection moulding, injection moulding in the afterbody of fixing bolt 1, for fixing bolt 1 increases supporting surface.
Described rubber spring 4 is vulcanization of rubber part, is formed by the vulcanization of rubber, and rubber is through the formula rate that multiple test draws and carries out mixing.
Described elasticity decoupler 8 is vulcanization of rubber part, is formed, for controlling the amount of flow of upper and lower two liquid chamber liquid by the vulcanization of rubber.
Described helical duct dividing plate 9 is aluminium diecasting, is formed by aluminium die casting, and liquid helical duct dividing plate 9 has inertia channel, liquid to-and-fro motion between upper and lower liquid chamber.The liquid energy produced that moves in inertia channel makes to suspend the characteristic with large damping, thus vibrational energy is dissipated rapidly, thus reaches the function of attenuation vibration.
Described counterdie 10 is vulcanization of rubber part, is formed by the vulcanization of rubber; For storing liquid.
Working principle of the present utility model: because during automobile normal running, vibration frequency low-amplitude is large, the movement of elasticity decoupler is large, hf channel near elasticity decoupler is sealed, now liquid only flows in low channel, because the resistance in passage produces larger damping constant, be conducive to stoping the vibration passing of motor to vehicle body, improve damping effect.When motor dallies in idling, vibration frequency is high and Oscillation Amplitude is less, certain hysteresis quality is there is in the mobile phase of liquid for external force, cause liquid cannot flow with applied vibration, the flowing of liquid can not be produced in low channel, now because amplitude is less, the amount of movement of elasticity decoupler is little, hf channel near elasticity decoupler can not be sealed, liquid motion is around driven during the motion of elasticity decoupler, the dynamic stiffness of hydraulic mount is reduced, thus improves the damping performance of hydraulic mount when high frequency.
In order to the impact protecting vibration damper not to be subject to road conditions and engine bin greasy dirt, sealed mode shell is increased outward at vibration damper, with rubber gasket sealing, rubber gasket can increase the damping effect that vibration damper is connected with motor simultaneously, improves hydraulic mount damping device overall performance and life-span; And only need change base and just can realize various general, meet the requirement of automobile industry modularized production.
The utility model structure is uncomplicated, overall development cost and processing cost low, and device stability, durability and practicability are higher, can play good damping effect.
