Description

A kind of gear box suspension
Technical field
It the utility model is related to a kind of gear box suspension system, more particularly to a kind of gear box suspension.
Background technology
The noise and vibration of automobile drastically influence the riding comfort of people, and more effective method is to use engine Suspension is vibrated to isolate.Its vibration source comes from engine, especially light truck, its engine quality is larger, and Idling wobble is acute It is strong, it is big that amplitude is overturn in start and stop.At present since configuration aspects limit, universal light truck power assembly all takes longitudinal to arrange, Engine is preceding, and gearbox is rear, and engine needs less dynamic stiffness during idling, and when start-stop needs larger rigidity.For this reason, Need to seek a kind of engine rubber suspension system to solve the above problems, can be saved while vehicle NVH performances are improved Cost.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of simple in structure, handling ease, cost is relatively low, vibration isolation effect The preferable gear box suspension of fruit.
In order to solve the above technical problems, a kind of gear box suspension provided by the utility model, including upper damping block, inner core, Lower damping block and fastener, the upper damping block are integrated with upper supporting plate, lower carrier plate by the vulcanization of rubber, the upper damping block position In bodyside bracket upper end, engine side stent is located at upper supporting plate upper end, and the bodyside bracket lower end is equipped with lower damping block, institute State lower damping block to be integrated by the vulcanization of rubber with spacing shim, the inner core is inserted among damping block and lower damping block, institute Stating fastener includes fastening bolt and clamp nut, and the engine side stent and spacing shim are respectively by fastening bolt and tight Gu nut is fastened on the top and bottom of inner core, and makes to form precommpression between damping block and lower damping block.
Further, the upper supporting plate is circular ring shape, and upper supporting plate is connected by positioning pin and the engine side stent of top.
Further, the lower carrier plate is circular ring shape, and the downward flange of inner ring of lower carrier plate, is inserted into bodyside bracket hole, And form interference fit.
Further, the endoporus upper end of the upper damping block and inner core transition coordinate, the endoporus lower end of upper damping block with it is interior Gap is left between core, and is formed radially spacing.
Further, after the lower damping block is integrated with spacing shim vulcanization and bodyside bracket forms axial limiting.
The beneficial effects of the utility model:The suspension of the utility model, is stuck in vehicle body at the lower carrier plate flange of upper damping block In side stand pilot hole, and it is interference fitted therewith, easy to assemble.Lower damping block is independent rubber block, is turned in engine start and stop When turning, lower damping block effectively can decay it, only can by adjusting lower damping block sizing material hardness in NVH performance adjustments It is convenient and efficient to meet rigidity requirement.I.e. in the utility model, upper and lower damping block is mutually independent component, each firm to it The adjustment of degree is convenient, flexible.
Brief description of the drawings
Fig. 1 is the assembly cross-sectional view of the utility model.
Fig. 2 is the upper damping block structure diagram of the utility model.
Fig. 3 is the lower damping block structure diagram of the utility model.
Embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further It is described in detail, which is only used for explaining the utility model, does not form the restriction to the scope of protection of the utility model.
As shown in Figures 1 to 3, a kind of gear box suspension of the utility model, including upper damping block 4, inner core 9, lower damping block 7 And fastener, upper damping block 4 are integrated with upper supporting plate 3, lower carrier plate 5 by the vulcanization of rubber, upper damping block 4 is located at bodyside bracket 6 upper ends, engine side stent 2 are located at 3 upper end of upper supporting plate,
6 lower end of bodyside bracket is equipped with lower damping block 7, plays the role of axial limiting, and lower damping block 7 is logical with spacing shim 8 Cross the vulcanization of rubber to be integrated, inner core 9 is inserted in damping block 4 and among lower damping block 7, engine side stent 2 and spacing shim 8 divide The top and bottom of inner core 9 are not fastened on by fastening bolt 1, clamp nut 10.
That is, fastening bolt 1 is inserted into inner core 9, and the upper supporting plate 3 of engine side stent 2 and spacing shim 8 are fastened on inner core 9 top and bottom, and make to form precommpression between damping block 4 and lower damping block 7.
Above-mentioned described upper supporting plate 3 is circular ring shape, and upper supporting plate 3 is connected by positioning pin 31 and the engine side stent 2 of top Connect.
Above-mentioned described lower carrier plate 5 is circular ring shape, and the downward flange of inner ring of lower carrier plate 5, is inserted into 6 hole of bodyside bracket, And form interference fit.I.e. upper damping block 4 steps up to subtract between the two, playing master by engine side stent 2 and bodyside bracket 6 Bestir oneself use.
The endoporus upper end of upper damping block 4 coordinates with 9 transition of inner core, between being left between the endoporus lower end of upper damping block 4 and inner core 9 Gap, and formed radially spacing.After lower damping block 7 is integrated with the vulcanization of spacing shim 8 and bodyside bracket 6 forms axial limiting.
The suspension of the utility model be using upper and lower two damping blocks and with bodyside bracket 2 and engine side stent 2 It is assembled into one, the vibration of engine is directly delivered to upper damping block 4, led to by 2 lower face of engine side stent as force surface It is delivered to after crossing rubber decay on bodyside bracket 2,2 upper surface of bodyside bracket and interstitial hole are as stress surface.
Lower damping block 7 is acted on for axial limiting, can improve engine start and stop by adjusting lower 7 sizing material hardness of damping block The phenomenon of upset.Suspension inner core and spacing shim 8 are fastened as a whole with engine side stent 2, when engine start and stop moment, its Upset drives engine side stent 2 to overturn, then spacing shim 8 is overturn at the same time, and damping block 7 can suppress this upset width at present for this Degree, achievees the purpose that to cut down vibration.
