Abstract
The utility model discloses an auxiliary fame connecting structure, which comprises an auxiliary fame main body, a right longitudinal beam, a cross beam assembly, a left installing rack and a right installing rack, wherein a plurality of connecting sleeves are arranged on the auxiliary frame main body, and a bolt is serially connected with an auxiliary frame vibration isolator assembly and is connected and fixed with a vehicle body after penetrating through the connecting sleeve. The utility model has the advantages that because a connecting lining is pressed in the connecting sleeve, the bolt at the front end is serially connected with the auxiliary frame vibration isolator, so that an auxiliary frame is flexibly serially connected with the vehicle body through a lining vulcanization layer and the vibration isolator, and an elastic vibration isolator is additionally arranged on the auxiliary frame installing rack at the rear end and is flexibly connected with the bolt, therefore the vibration isolating and noise reducing functions of the auxiliary frame are enhanced and the control stability of the whole vehicle is indirectly improved.
Description
Technical field
The utility model relates to the field, chassis of automobile, and more particularly, the utility model relates to a kind of subframe frame connecting structure.
Background technology
Subframe is the max architecture spare of passenger-car chassis, and its basic design needs chassis function parts such as assembly chassis deflector, swing arm, stabilizer rod, but also needs the assembling dynamic assembly suspension, constitutes chassis module on this basis.Subframe not only need satisfy the assembling needs of each parts, and needs enough strength and stiffness, is unlikely to deform under the load input to guarantee each; Improve the globality and sturdy sense on chassis, promote the road-holding property of car load indirectly, in the vehicle operating process; Come from ground-surface application force and vibration meeting propagated, finally be fed back to the motion of vehicle body and occupant's subjective feeling, therefore along tire-Control arm-subframe-vehicle body; The cushioning performance of subframe is particularly important, and at present, subframe is connected with vehicle body; Normally through the through hole direct connection, or through the connection of mono-metal sleeve, because above-mentioned connection mode is that metal cooperates with metallo-; Cause vibration and noise directly to be passed to vehicle body, can not reach the purpose of subframe vibration insulation and noise reduction.
Like the Chinese patent Granted publication number is CN 201484497 U, and Granted publication day is the patent application case of 2010-05-26, discloses a kind of sub-frame connecting structure; Comprise the subframe body; Described subframe body is provided with the sleeve that a plurality of line of centerss are level attitude, and sleeve passes sleeve through bolt and the body contact structure is fixed, and this scheme can effectively realize subframe vibration damping purpose in the horizontal direction; Its weak point is that this scheme effectiveness in vibration suppression in vertical direction is relatively poor.
The utility model content
The purpose of the utility model is the problem that solves the vibration insulation and noise reduction function difference of subframe in the prior art, and a kind of vibration insulation and noise reduction function ratio that flexibly connects subframe frame connecting structure preferably is provided.
In order to solve the problems of the technologies described above; The utility model takes following technical proposals to be achieved: a kind of subframe frame connecting structure; Comprise subframe main body, right vertical beam, left longeron, crossbeam assembly and left installation bracket and right mounting bracket; Said subframe main body is provided with a plurality of connector bushings, and bolt serial connection subframe vibration isolating pad assembly is fixed with body contact after passing this connector bushing again.The subframe frame connecting structure of this programme; Because through connector bushing and subframe vibration isolating pad assembly and body contact; Subframe is unlikely down deforms to load input not only to have guaranteed each, strengthens chassis whole property and sturdy sense, and has effectively realized the vibration damping purpose of subframe in level and vertical direction; Reach the engine request of subframe vibration insulation and noise reduction, promoted the road-holding property of car load indirectly.
As preferably, be provided with the connection lining in the said connector bushing.Like this, can alleviate the vibration of subframe and vehicle body.
As preferably, said connection lining comprises inner sleeve and outer tube, between inner sleeve and outer tube, is provided with sulfuric horizon.Realize the decay of vibration transfer through sulfuric horizon thickness.
As preferably, fixing between said connector bushing and the subframe main body through welding, between connector bushing and the outer tube interference fit.This kind connection mode is simple, stable.
As preferably, said left installation bracket and right mounting bracket are provided with the elastic vibration isolation pad.Elastic vibration isolation pad and bolt flexibly connect, can buffering vibration.
As preferably, said subframe main body is provided with the connecting bore that connects right vertical beam, left longeron, is provided with rubber cradle in the connecting bore, and right vertical beam, left longeron are connected with the subframe main body through bolt.Require low point of connection for vibration and noise reducing, this kind connection was both simple, was prone to assembling, can realize vibration damping again.
The beneficial effect of the utility model is: the subframe frame connecting structure of the utility model; Owing in its connector bushing, be pressed into the connection lining, be serially connected with subframe vibration isolating pad assembly at preceding terminal bolt, make and realize flexible linking through lining sulfuric horizon and vibration isolating pad between subframe and vehicle body; The rear end also adds the elastic vibration isolation pad on the subframe mounting bracket; Flexibly connect with bolt, thereby strengthened the vibration insulation and noise reduction function of subframe, promoted the road-holding property of car load indirectly.
