Description
Technical field
The utility model relates to technical field of automobile engine, is specifically related to a kind of mounting assembly.
Background technology
Noise, vibration and sound vibration roughness (its english abbreviation NVH) are global questions weighing the Automobile manufacturing quality.The NVH technology that suspends and relate to automotive engine of automobile.Suspending is the critical component of dynamic assembly vibration isolation, and reasonably suspension member should be able to realize its functional requirement, and lower cost is arranged, and weight is suitable, and space hold is little, and is easy to assembly, and profile attractive in appearance is arranged.
Existing driving engine back stay suspends as shown in Figure 1, and its large end 10 is circular, and is larger in mandrel requirements of installation space radially, and the installing space of mandrel and vehicle body is from longer, NVH degradation in the vehicle movement process so that in the car.Simultaneously, it adopts circular hole to be connected with large end connection bracket, in total process of assembling of suspension system, for the stressed adjusting that can not carry out appropriateness of the rear-suspending static load of making and assembly error causes, the risk that increases the idling vibration is arranged.Its small end 9 is connected by the bolt that crosses with the driving engine side stand, and the risk of torque creep is arranged.
The utility model content
The utility model provides a kind of and anti-has turned round rod-pulling type rubber mounting assembly, and its demand on installing space is less, can appropriate regulation or to eliminate the anti-static load of turning round the large end of pull bar rubber mounting stressed, be difficult for torque creep; This mounting assembly is lightweight, easy for installation simultaneously, and the NVH performance of car load is improved.
The technical solution of the utility model is as follows:
The utility model proposes and a kind ofly anti-turn round rod-pulling type rubber mounting assembly, comprise large end connection bracket and anti-ly turn round pull bar and suspend; Described anti-turn round pull bar suspend comprise large end connection bracket, greatly hold mandrel, hold rubber damping body, centre link, small end mandrel and small end rubber damping body greatly.The two ends of centre link are large end mounting hole and small end mounting hole respectively.Large end mandrel puts in the large end rubber damping body, and both sulfurations are fixed in the large end mounting hole of centre link.The small end mandrel passes small end rubber damping body, and both sulfurations are fixed in the small end mounting hole of centre link.Described large end mandrel has central shaft hole, holds greatly connection bracket to be connected with large end mandrel by cross bolts, holds greatly the bolt hole that has on the connection bracket with the axis hole perpendicular direction of large end mandrel, is connected with vehicle body by vertical bolt; Described small end mandrel is solid barred body, and its two ends have and bolt hole perpendicular to small end mandrel axis, are connected with the driving engine side stand.
Large end connection bracket is connected with large end mandrel by cross bolts, and the bolt hole that is connected with large end mandrel is waist shaped hole, and length direction is parallel to vehicle body.The large end mounting hole profile of described centre link and to hold greatly the rubber damping body be a nearly ellipsoid, hollow out in the body, ellipsoidal major axis is parallel to vehicle body.
The middle part of described small end mandrel is fluted, and described small end rubber damping body is tubular structure, and the middle part sulfuration has projection in the cylinder, with the groove coupling on the small end mandrel.
The cylinder two ends, outer ring of described small end rubber damping body are formed with the rubber ring of two circle grooves and outer arch.
The middle part of described centre link is provided with lightening grooves or hole.
Described large end rubber damping body has a rubber herringbone structure to connect ellipsoid inner ring and ellipsoid outer ring in the centre sulfuration.This people's font place of converging is a through hole, and on ellipsoid, the position sulfuration corresponding with people's font top and bottom has rubber projections.
The utility model adopts large end rubber damping body to be a near ellipsoid structure, and is less to space requirement radially, is convenient to install, and compares because mandrel and vehicle body installing space are shorter with suspending in the past, and the motion of vehicle body is stressed better.Little to taking assembly space, in the time of in it is connected in the tunnel beam, can reasonably arrange, for the vibration uncoupling of dynamic assembly facilitates, namely reduced the requirement to the suspension arrangement space, satisfied again the NVH performance of the monomer that suspends simultaneously.
Suspend about under the static load state finish installation after, owing to make and assembly error, dynamic assembly generation small angle deflection is compared the generation deviation with desirable design point, adopting waist shaped hole to cooperate by large end mandrel with large end connection bracket can be at a certain amount of small angle deflection of eliminating, make stressed try one's best little of body side under the static load state, thereby can necessarily regulate the rear-suspending under the static load is stressed.
Small end mandrel that this suspends use to lower and on the vertical two bolts that pass through be connected with engine bed, compare with the small end type of attachment that suspended in the past and can not produce torque creep, the while dismounting is more convenient, coupling stiffness is stronger.
Because whole mounting assembly has also been taked the loss of weight groove of centre link or the design in hole, so that the weight saving of this assembly.
