Description
Technical field
The utility model belongs to automotive field, especially relates to a kind of Automotive transmission that is used to support change-speed box stop gear that suspends.
Background technology
The main effect of automobile power assembly suspending is supporting and is connected dynamic assembly, bears the dynamic and static load under the various operating modes, controls the displacement that dynamic assembly is gone up in any direction, to such an extent as to the cabin in other parts and vehicle body do not interfere; In addition, also to realize absorbing, vibration isolation, noise reduction, satisfy the requirement of car load noise, vibration and traveling comfort.Existing suspending mechanism adopts rubber mounting more, and by sheet metal component and Rubber Parts process sulfidization molding, sheet metal component is as attaching parts, and Rubber Parts is as shock absorber part.Rubber Parts has the space spring performance; Can bear the load of a plurality of directions; Absorbed oscillation and impact energy preferably, but, cause dynamic assembly under limiting conditions such as drag, brish acceleration, low speed collision, to produce bigger position and angular distortion also just because of the space spring performance of Rubber Parts; Interfere thereby cause change-speed box and accessory system and vehicle body to produce, influence complete vehicle quality and parts service life with other annexes; In addition, the existing change-speed box stop gear that suspends has only the not anti-function of reversing of three-dimensional position limiting structure; Structure takes up room greatly, needs secondary to connect (vehicle frame).
The utility model content
The technical matters that the utility model will solve provides a kind of change-speed box stop gear that suspends, be positioned at change-speed box by two and suspend on the center line (car load Y to), through with realize suspending the anti-function of reversing cooperating of the upper and lower skeleton that suspends;
The caging bolt that suspends is that the integral type bolt directly runs through the skeleton that suspends, press-fits the lower skeleton that suspends, and caging bolt is simultaneously as bolt of rear end plate and vehicle frame direct connection, have space hold little, simple to operation, do not need other parts connection characteristics of secondary usefulness.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of change-speed box stop gear that suspends; Comprise the upper skeleton that suspends, the lower skeleton that suspends, rubber bodies; Also comprise two caging bolts that suspend; Rubber bodies the upper skeleton that suspends, suspend between the lower skeleton and with the two integrated vulcanizing moulding, its special feature is: two caging bolt through holes that suspend pass the upper skeleton that suspends and connect the lower skeleton that suspends, the upper skeleton that suspends, lower skeleton and suspend and be the polysulphide rubbers body between the caging bolt suspends.
Be the basic structure of the utility model more than, the upper skeleton that suspends, suspend lower skeleton and suspend caging bolt and rubber bodies integrated vulcanizing shaped structures can prevent that the metal direct contact from producing noise and damaging mounting assembly; Caging bolt is simultaneously as bolt of rear end plate and vehicle frame direct connection.The utility model can realize that three-dimensional is spacing and reverse around the Y axle, specifically is achieved in that the caging bolt nut that suspends, the lower skeleton that suspends accomplishes Z to spacing with the upper skeleton confined planes that suspends; Suspend caging bolt and the upper skeleton spacing hole that suspends accomplish X to Y to spacing; Article two, the caging bolt that suspends is accomplished with the upper skeleton spacing hole (two) that suspends and is reversed around the Z axle.
Qualification as the utility model:
The caging bolt nut that suspends is the setting of formations " worker " font with the lower skeleton that suspends, suspend the caging bolt cap and on suspend and have the gap between the skeleton, suspend upper skeleton and dynamic assembly suspend relatively lower skeleton Z to displacement gap qualification thus.
Said Z to displacement be 10-15mm.
Suspend upper skeleton and dynamic assembly with respect to suspend lower skeleton X, Y to displacement, spacing by the tolerance clearance that suspends the upper skeleton through hole and suspend between the caging bolt.
Said suspend upper skeleton and dynamic assembly with respect to suspend lower skeleton X, Y to displacement be 5-10mm.
Suspend upper skeleton and suspend and have tolerance clearance between the caging bolt, the upper skeleton that suspends is limited said tolerance clearance around the maximum anglec of rotation of Z axle.
The maximum anglec of rotation is 5-8 °.
The effect that suspends is a nonrigid connection to dynamic assembly to be provided, and this purpose is to realize through above-mentioned means, requires can have between respective members certain displacement to cushion the stressed of dynamic assembly.If corresponding gap is too small, buffer action is not obvious; And excessive clearance, thereby rubber section branch excessive deformation causes failure of apparatus, therefore corresponding displacement (control through the gap realizes) has been carried out the optimization restriction on the size, and preferable with the technique effect that guarantees the utility model.
Owing to adopted above-mentioned technical scheme, the acquisition of technology progress of the utility model institute is:
1, two caging bolt through holes that suspend pass the upper skeleton that suspends to connect the lower skeleton that the suspends three-dimensional that realizes suspending spacing and around car load Z axle twisting action; The suspend upper and lower skeleton and the polysulphide rubbers body between the caging bolt that suspends prevent that the metal direct contact from producing noise and damaging mounting assembly.
2, two caging bolt functions that suspend have two kinds: suspend spacing and the installation that suspends, the caging bolt that suspends is realized limit function through running through the upper skeleton that suspends, and caging bolt is simultaneously as bolt of rear end plate and vehicle frame direct connection.
The utility model is applicable to various vehicles, and the change-speed box in the automobile power assembly is carried out mount supports.
The utility model below will combine Figure of description and specific embodiment to do further explain.
