Description
Technical field
The utility model relates to a kind of anchor fitting of automobile gearbox.Relate in particular to a kind of ball-and-socket hinge style auxiliary suspension mechanism of automobile gearbox.
Background technology
Development along with automotive technology, the use of heavy change speed gear box and retarder, the weight and the axial length of change speed gear box have all been increased, and the moment of deflection that this has just increased engine cylinder-body aft end face and clutch bell junction, clutch bell and clutch case junction greatly is easy to generate cracking phenomena; And long change speed gear box axial length is also totally unfavorable to the vibration of car load.This just need increase auxiliary suspension mechanism on change speed gear box, the basic demand of auxiliary suspension provides support, and rigidity is little, and the excessive displacement of opposing above-below direction does not limit the displacement of other directions.At present, there are following problems in existing auxiliary suspension on the market.The first, the predetermincd tension when change speed gear box auxiliary suspension mechanism installs is excessive, is easy to generate constraint.The second, change speed gear box auxiliary suspension mechanism attachment point is easy to generate stress concentration.The 3rd, change speed gear box auxiliary suspension mechanics limit the displacement of dynamic assembly on some direction.As the Chinese patent notification number: CN 2759824Y, the day for announcing: on February 22nd, 2006, utility model title: " change speed gear box auxiliary suspension ", proposed by stabilizer rod, the auxiliary suspension mechanism that vehicle frame cushion assembly and change speed gear box cushion assembly are formed, the interlude of stabilizer rod is installed on the gear box casing by the change speed gear box cushion assembly, its two ends are fixed on the car body by the vehicle frame cushion, do not need to apply precompressed compression during installation, can carry out spacing effectively, vibration damping, stress concentration is little, good reliability, but limited the displacement of change speed gear box left and right directions too much, be difficult to resist the excessive displacement of above-below direction again.
Summary of the invention
The purpose of this utility model is bigger at existing auxiliary suspension device rigidity, it is serious to cross the constraint phenomenon, the horizontal hunting displacement is little, attachment point stress is bigger, defective that aseismicity is relatively poor and deficiency, it is little to propose a kind of rigidity, little to the horizontal hunting amount of restraint, the ball-and-socket hinge style auxiliary suspension mechanism of the automobile gearbox of vibration damping and good buffer effect.
The purpose of this utility model realizes in the following manner: a kind of ball-and-socket hinge style auxiliary suspension mechanism of automobile gearbox, comprise pipe link, the two ends up and down of described pipe link are respectively arranged with ball pivot and following ball pivot, the ball pivot center of last ball pivot and following ball pivot is equipped with through hole, one end of last ball pivot and cushion carriage all is hinged on the bracket bolt pair, following ball pivot all is hinged on the bracket bolt pair with an end that is connected support, the other end of cushion carriage is connected with cross member of frame, and the other end that connects support is connected with change speed gear box.
The other end of cushion carriage described in the utility model is connected with cross member of frame through cushion assembly.
Cushion assembly described in the utility model is formed by cushion, front band, lower catch hoop and two group cushion assembly bolts are secondary at least, at least be provided with two axially extending bores on the cushion, two groups of cushion assembly bolt pairs are passed the axially extending bore of cushion respectively and are captiveed joint with the other end of cushion carriage, corresponding clip is held front band and lower catch hoop on the outside face of cushion, and front band and lower catch hoop are through being bolted on the cross member of frame.
The following rod end joint set of ball pivot becomes pipe link described in the utility model with being connected down by connecting the last rod end joint of going up ball pivot, and the end correspondence in last rod end joint and following rod end joint is provided with the internal and external screw thread that can screw mutually.
The utility model can also be provided with externally threaded on rod end joint or down be combined with jam nut on the rod end joint.
The utility model can also be provided with joint pad with following ball pivot with the contact site that is connected support with the contact site of cushion carriage at last ball pivot.
The axis of bracket bolt pair described in the utility model and bracket bolt pair and the axis of output shaft of gear-box are perpendicular.
By connecting support the last ball pivot of cushion bracket and last rod end joint one end is coupled together, change speed gear box connects support the following ball pivot of change speed gear box and following rod end joint one end is linked together.When being subjected to the above-below direction application force, rod end joint assembly moves up and down, and drives cushion and produces shear deformation, because the distortion of cushion is limited, so can reach vibration damping and spacing requirement.
When being subjected to other directive effect power, rod end joint assembly will be swung, and center of oscillation is a ball pivot on the last rod end joint that links to each other with cushion bracket, swing point be with the change speed gear box bonded assembly under ball pivot under the rod end joint.The swing of rod end joint assembly, can not produce dynamic assembly spacing, but the distortion by cushion can be played the effect of buffering and vibration damping.
Therefore, compared with prior art the utlity model has following tangible advantage:
By support cushion is fixed on the cross member of frame, support has strengthened the area of contact with cross member of frame, helps preventing stress concentration; And the distortion in cushion when work is shear deformation, and rigidity is little, can better absorb the vibration of change speed gear box, plays the effect of noise reduction.
By regulating the jam nut of rod end joint assembly, change speed gear box is applied certain predetermincd tension, play the effect of support.
By the motion of rod end joint assembly, play vibration damping and spacing effect when making up-and-down movement, and the motion of other directions is not spacing, only plays the effect of vibration damping.Simultaneously, the phenomenon of play before and after the dynamic assembly can play the effect of buffering during to brake and acceleration.
