Description
Technical field
The utility model relates to current vortex retarder and is arranged on the parts that safety performance on middle-size and small-size truck, passenger vehicle and damping performance promote, in particular to a kind of shock-damping structure for current vortex retarder.
Background technology
Vehicle retarder is the important spare part that motor vehicle braking system is conventional, mainly comprises the types such as eddy current retarder, magnetic force retarder, hydrodynamic retarder.Shock-damping structure in retarder plays vital effect to the braking of whole retarder, especially in the time that retarder is arranged on middle pickup, passenger vehicle, to shaking sensitivity, the damping effect of shock-damping structure of the prior art a little less than, therefore after installing retarder additional, the balance of car load is had to larger impact, have very big probability to cause vehicle to shake, the traveling comfort to vehicle, stability, safety all affect.
As shown in Figure 1-2, shock-damping structure of the prior art comprises inner sleeve (2), shock reducing structure (4) and large pad (6), described shock reducing structure (4) is the cylinder that has through hole in the middle of, and two shock reducing structures (4) are set in the supporting plate (7) that inner sleeve (2) assembles rear and retarder (20) by hex-head nut (3) and hex bolt (5) after upper and link together; Two shock reducing structures (4) link together by adapter plate (1) and frame beam (20) with the lower end of hex-head nut (3), hex bolt (5) assembly parts.As seen from Figure 2, between two shock reducing structures (4), separated completely by supporting plate (7), and the external diameter curved surface of the aperture curved surface of supporting plate (7) and inner sleeve (2) is fitted completely, because supporting plate (7) and inner sleeve (2) are rigid material, therefore it forms hardness connection in the time of two rigid mechanical parts laminatings, caused the damping effect of whole shock-damping structure to weaken, balance is poor, and greatly the vehicle that causes of probability is shaken, and vehicle riding comfort, stability, safety are all affected.
For example Granted publication number is the Chinese invention patent of CN102050031A, it discloses a kind of mounting structure of current vortex retarder, comprise adapter plate, hexagonal bar iron, large pad, support, upper cushion blocking, inner sleeve, hexagonal nut, etc. structure, adapter plate adopts " L " shape, hanging of the prior art is installed and changed the installation of holder formula into, and on adopting, lower cushion blocking connection structure replaces integral type cushion blocking of the prior art, improve damping effect, before and after adapter plate, both sides are welded with accessory plate, play the effect of good holder lining, increase installation reliability, improve current vortex retarder service life.Between two shock reducing structures, separated completely by supporting plate, and the aperture curved surface of supporting plate and the external diameter curved surface of inner sleeve are fitted completely, because supporting plate and inner sleeve are rigid material, therefore it forms hardness connection in the time of two rigid mechanical parts laminatings, caused the damping effect of whole shock-damping structure to weaken, balance is poor, and greatly the vehicle that causes of probability is shaken, and vehicle riding comfort, stability, safety are all affected.
Again for example with the utility model patent of above-mentioned application of the same clan, Granted publication number is CN201863729, a kind of mounting structure of current vortex retarder, comprise adapter plate, hexagonal bar iron, large pad, support, upper cushion blocking, inner sleeve, hexagonal nut, etc. structure, adapter plate adopts " L " shape, hanging of the prior art is installed and changed the installation of holder formula into, and on adopting, lower cushion blocking connection structure replaces integral type cushion blocking of the prior art, improve damping effect, before and after adapter plate, both sides are welded with accessory plate, play the effect of good holder lining, increase installation reliability, improve current vortex retarder service life.Between two shock reducing structures, separated completely by supporting plate, and the aperture curved surface of supporting plate and the external diameter curved surface of inner sleeve are fitted completely, because supporting plate and inner sleeve are rigid material, therefore it forms hardness connection in the time of two rigid mechanical parts laminatings, caused the damping effect of whole shock-damping structure to weaken, balance is poor, and greatly the vehicle that causes of probability is shaken, and vehicle riding comfort, stability, safety are all affected.
Utility model content
The above-mentioned technological deficiency existing in order to solve prior art, the purpose of this utility model is to provide a kind of shock-damping structure for current vortex retarder, existing structure is that the structure by improving cushion blocking first contacts inner sleeve with cushion blocking, cushion blocking contacts with supporting plate again, so just avoid the hard connection of mechanical part, promote damping effect, vehicle riding comfort, stability, safety have been had to great enhancing.Matching to retarder in entrucking has also obtained reinforcement, has also greatly improved the competitive power of retarder on remoulded car market simultaneously.
In order to realize above-mentioned design goal, the scheme that the utility model adopts is as follows:
A kind of shock-damping structure for current vortex retarder, comprise inner sleeve, shock reducing structure and large pad, described shock reducing structure is a cylinder with boss, centre has through hole, after putting, links together by hex-head nut and hex bolt assembling supporting plate rear and retarder in two shock reducing structures are set in.
Preferably, the lower end of described two shock reducing structures and hex-head nut, hex bolt assembly parts links together by adapter plate and frame beam.
In above-mentioned arbitrary scheme, preferably, described shock reducing structure is selected natural rubber material.Experiment showed, that the shock reducing structure in current vortex retarder selects natural rubber material to have: shock-stiffness reduces, damping effect is good, long service life, the advantage such as cheap, therefore the shock reducing structure in the utility model is selected natural rubber material manufacture.
In above-mentioned arbitrary scheme, preferably, the hardness of described shock reducing structure is 55 to continue you.Shock reducing structure in the utility model is selected natural rubber material manufacture, experimental results show that its hardness to continue by original 70 you are reduced to 55 and continue you, makes the damping effect of shock reducing structure better.
In above-mentioned arbitrary scheme, preferably, the external diameter of the boss of described shock reducing structure is greater than the external diameter of inner sleeve.
In above-mentioned arbitrary scheme, preferably, the external diameter of the boss of described shock reducing structure is less than or equal to the aperture of supporting plate.
When the assembly parts putting in two shock reducing structures are set in and supporting plate link together, because the external diameter of the boss of shock reducing structure is greater than the external diameter of inner sleeve, and the external diameter of the boss of shock reducing structure is less than or equal to the aperture of supporting plate, at this moment together with the external diameter application of a surface of the curved surface of the intermediate throughholes of shock reducing structure and inner sleeve, the external diameter of the endoporus curved surface of supporting plate and the boss of shock reducing structure fits together, because inner sleeve is rigid element, the hard connection of these two mechanical parts of supporting plate and inner sleeve avoided in such improvement design, promote damping effect, to vehicle riding comfort, stability, safety has great enhancing.
