Abstract
The utility model relates to a bush type rubber suspended buffering mechanism installed above a transmission gear. A tubular shell of the mechanism is internally provided with a main rubber spring, and a connecting support is arranged outside one end of the tubular shell; the shell is also internally provided with a cylindrical limiting block, one end of the cylindrical limiting block is in contact with an aluminum core, and the other end of the cylindrical limiting block extends outside the shell and is in contact with the connecting support; the outer end surface of the shell is adhered with a rubber gasket, and the aluminum core, the limiting block and the connecting support are fixedly connected together through two bolts; the periphery of the limiting block at the end in contact with the aluminum core is provided with an outwards convex circular bead, and a gap A is axially arranged between the opposite ends of the circular bead and the shell; and a gap B is arranged between end surfaces of the rubber gasket and the connecting support. When a power assembly moves towards the right side, the limiting block can be in contact with the inner wall of the shell, and when the power assembly moves towards the left side, the connecting support can be in contact with the buffering rubber gasket so that the effects of limiting, buffering and protecting the peripheral parts of the power assembly are achieved.
Description
Technical field
The utility model belongs to the fixed installation technical field of automobile power assembly, is specifically related to be used for the damping mechanism that suspends that install the gearbox top.
Background technique
Be used for not only can the decay vibration of power assembly of the hard-wired damping mechanism that suspends of automobile power assembly; Prevent that vibration is to the vehicle body transmission; Can also isolate the influence of vibration engine operation that produces because of Uneven road, thereby the protection motor is the important component part of passenger car vibration performance.Be used for the hard-wired damping mechanism that suspends of automobile power assembly except that the effective attenuation vibration, the effect of restricted power assembly over-large displacement also will be arranged.At present mostly the bush type rubber mounting is rubber spring directly compressed into that standard-sized sheet is put or the semi open model sleeve pipe; Support will be connected then and rubber spring is fixed; This structure is unfavorable for that power assembly is in the horizontal displacement control of car load; Vehicle is when taking a sudden turn or bumping, and the power assembly displacement is excessive, causes peripheral component to lose efficacy and damage.
Summary of the invention
In order to solve the spacing problem of power assembly under the limited conditions, improve spacing reliability simultaneously, the bush type rubber mounting damping mechanism that is used for the installation of gearbox top that the utility model provides a kind of improved limiting stopper and spacing pad to combine.
Concrete improved technological scheme is following:
Be used for the bush type rubber mounting damping mechanism that install the gearbox top, comprise the housing of tubulose, be provided with aluminium core and rubber spring in the housing; The two becomes integral body through sulfuration; The outside end of tubular shell is provided with the connection support, also is provided with limiting stopper in the housing, and limiting stopper is cylindric; The one of which end contacts with the aluminium core, and the other end extends outside the housing, and be connected support contact; The exterior edge face of housing is bonded with rubber pad, aluminium core, limiting stopper and be connected support and link together through two bolt; The limiting stopper periphery that contacts an end with the aluminium core is provided with the shoulder of evagination, is axially arranged with gap A between said shoulder and the housing corresponding end; Be provided with gap B between said rubber pad and the connection bracket end face.
Axial clearance A between the shoulder of said limiting stopper and the housing corresponding end is 7 ㎜.
Said rubber pad and the gap B that connects between the bracket end face are 6 ㎜.
The useful technique effect of the utility model is: when power assembly moves right; Limiting stopper can contact with inner walls; Power assembly is when left movement, and connecting support can contact with buffer rubber gasket, reaches the effect of spacing buffering, protection power assembly and circumferential component.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model sectional view.
Sequence number among the last figure: rubber pad 1, limiting stopper 2, housing 3, aluminium core 4, rubber spring 5, connection support 6, outer skeleton 7, bolt 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Embodiment:
Referring to Fig. 1; The bush type rubber mounting damping mechanism that is used for installing the gearbox top comprises the housing 3 of tubulose; Through columned aluminium core 4 rubber spring 5 is installed in the housing 3, the housing 3 one end outsides of tubulose are equipped with and connect support 6, are laid with three outer skeletons 7 on housing 3 excircles.Limiting stopper 2 also is housed in the housing 3; Limiting stopper 2 is cylindric, and the one of which end contacts with aluminium core 4, and the other end extends outside the housing 3, and contacts with being connected support 6, and the exterior edge face of housing 3 is bonded with rubber pad 1.Aluminium core 4, limiting stopper 2 and be connected support 6 and be fixed together through two bolts 8.Limiting stopper 2 peripheries that contact an end with aluminium core 4 are provided with the shoulder of evagination, are axially arranged with gap A between shoulder and the housing corresponding end, and gap A is 7 ㎜.Be provided with gap B between rubber pad 1 and connection support 6 end faces, gap B is 6 ㎜.
When power assembly amount of exercise to the right surpassed preset gap A value, limiting stopper 2 contacted with housing 3 inwalls; When power assembly when amount of exercise surpasses preset gap B value left, connection support 6 contacts with rubber pad 1, can immediately the motion of power assembly be restrained.
