Description
Technical field
The present invention relates to a kind of noise silencer of the exhaust system that is used for flexibly hanging power actuated vehicle and be used for absorbing silencer and vehicle body between the silencer hanging bracket (muffler hanger) of vibration.
Background technology
The function of this silencer hanging bracket be prevent to comprise noise silencer and freeing pipe the exhaust system constituent elements up and down or vertical shake be delivered on the vehicle body, provide resilient mounting for the noise silencer that is draped simultaneously.In order to realize this function satisfactorily, traditional silencer hanging bracket is designed to make its spring rigidity minimum as far as possible in vertical direction, that is to say, makes silencer hanging bracket soft as far as possible in vertical direction.
Fig. 5 A, Fig. 5 B and Fig. 5 C show disclosed design among as an example the Japanese Patent No.2585805.In Fig. 5 A, Fig. 5 B and Fig. 5 C, 200 expressions are had the silencer hanging bracket of the rubber elastomer formation of " θ " shape by integral body.More specifically, silencer hanging bracket 200 comprises: the rubber annulus 202 of the lengthwise that extends continuously in a circumferential direction; On left and right directions (that is left and right vehicle wheel direction), make the interconnective connection rubber part 204 of zone line of vertical direction of the rubber annulus 202 of lengthwise.In the interior zone of the rubber annulus 202 of lengthwise, upper space 206 is respectively formed at upside and the downside that is connected rubber part 204 with lower space 208.Mounting hole 210,212 forms respectively along the top and bottom of fore-and-aft direction by rubber annulus 202 up and down.In addition, in order to limit rubber annulus 202 excessive displacement vertically, retention tab 214,216 is set.
This silencer hanging bracket 200 that is made of rubber elastomer is used for installing in the mode shown in Fig. 5 B, make the supporting pin 218 of body side cooperate with last mounting hole 210, the supporting pin 220 of noise silencer side cooperates with following mounting hole 212, thereby flexibly support the noise silencer that is in suspension status, between vehicle body and noise silencer, provide damping of vibrations simultaneously.
Because the existence of upper space 206 and lower space 208, these silencer hanging bracket 200 integral body produce elastic deformation easily in vertical direction.That is to say that the spring rigidity on the vertical direction is low, therefore, suspension bracket can vertically support noise silencer flexibly and flexibly.
Yet, need to use two silencer hanging brackets 200, the problem that this causes number of parts to increase with this mode resilient mounting noise silencer 222.In addition since on the left and right vehicle wheel direction with respect to the weak holding capacity of the action (waving) of noise silencer 222, this noise silencer 222 also has problems aspect vehicle riding comfort.
For example, along with vehicle ' is passed through bend, vehicle body will a little outwards wave owing to centnifugal force.If the edge of silencer hanging bracket 200 laterally (left and right vehicle wheel direction) holding capacity too a little less than, then noise silencer 222 can not as one man move with vehicle body this moment, but will outwards move after postponing.When vehicle comes off the curve when recovering straight line path and travelling subsequently, vehicle body recovers its initial posture, and noise silencer will return its initial position after postponing.This moment the moving to have and lingeringly be delivered to vehicle body of noise silencer 222, the result, passenger's travelling comfort will suffer damage in the car.

When being installed in silencer hanging bracket 10 on the vehicle with the state on the silencer hanging bracket 10 of acting in a downward direction such as the weight of noise silencer, freeing pipe etc. subsequently, first mounting hole 38 and a pair of about second mounting hole 40 along continuous straight runs is in line, make from left to right to limit straight line.That is to say, in the present embodiment, 3 mounting holes, promptly, first mounting hole 38 and a pair of about second mounting hole 40 arrange with following position relation: under the Centered situation in hole, the position vertically of the position vertically of first mounting hole 38 and second mounting hole 40 partially overlaps, in other words, when when the left and right vehicle wheel direction is seen, these mounting holes 38 and 40 are with overlapping.Under the state that is installed on the vehicle, can be vertically stagger in the scope of ± 6mm in the position at the center, hole of first mounting hole 38 and second mounting hole 40.Under this state, the main portion 30 of rubber arm 14 is disposed in respectively between first mounting hole 38 and a pair of second mounting hole 40.
Though in Fig. 2, first mounting hole 38 is shown to be cooperated with the supporting pin 42 of body side, and illustrate a pair of about second mounting hole 40 cooperate with the supporting pin 44 of noise silencer side, but, also can be as shown in Figure 3, utilize first mounting hole 38 with cooperate from the upwardly extending supporting pin 44 of noise silencer side and utilize a pair of about second mounting hole 40 cooperate fix a silencer suspension bracket 10 with the supporting pin 42 that extends from body side downwards.
In the silencer hanging bracket 10 of present embodiment, the elastic deformation vertically by rubber arm 14 absorbs input vertically.Like this, be out of shape the input that fully absorbs vertically by elasticity of shearing.Therefore, spring rigidity vertically will reduce.On the other hand, response is along the input of left and right directions, and rubber arm 14 will bear elasticity of compression distortion, and perhaps more precisely, a side pressure is contracted, and opposite side stretches.Therefore, along the spring rigidity of left and right directions with height.For this reason, when with vehicle travel that noise silencer vertically vibrates explicitly the time because the spring rigidity vertically of rubber arm 14 is low, will absorb this vibration well, thereby reduce effectively or prevent that the vibration of noise silencer is passed to vehicle body.
In addition, at noise silencer when the left and right vehicle wheel direction is shifted with respect to vehicle, because silencer hanging bracket 10, more specifically rubber arm 14 along the spring rigidity height of left and right directions (promptly, bear on the noise silencer along the level height of the power of left and right directions), can prevent effectively that noise silencer is shifted relatively along left and right directions.
In the present embodiment, because silencer hanging bracket 10 only is made of rubber elastomer, therefore, rubber arm 14 wide displacement in vertical direction will cause excessive strain in the connecting portion office between the widened section 20 of the main portion 30 of rubber arm 14 and rubber annulus 12.As a result, this strain will be passed to stopping part 34,36 up and down.Stopping part 34,36 will bear compression/tensile deformation up and down, and this causes the nonlinear spring characteristic of silencer hanging bracket 10, thereby limit the excessive displacement of rubber arm 14 or the excessive displacement of rubber arm 14 is minimized.
In addition, when being flexible rubber arm 14 in vertical direction when equidirectional further bears appreciable relative displacement, will demonstrate stopping function by the contact between last stopping part 34 and 24 or by the contact between the stopping part 36 and 26 down.This stopping function will prevent the excessive displacement vertically of rubber arm 14 effectively.Therefore, although the silencer hanging bracket of present embodiment 10 spring rigidity vertically is soft, it has the high-durability to vertically repetition displacement.
In the present embodiment, second mounting hole 40 is formed on the centre that is positioned at vertical direction of rubber annulus 12 and has widened section 20 places of maximum side-to-side dimensions, this feasible space that can obtain be used to form second mounting hole 40 by rubber annulus 12.
In addition, form because second mounting hole 40 passes through the widened section 20 of rubber annulus 12, therefore, this makes whole rubber arm 14 can bear elastic deformation vertically.This makes and can easily reduce the spring rigidity vertically of rubber arm 14 or the spring rigidity vertically of rubber arm 14 is minimized.
In addition, last stopping part 34 and following stopping part 36 have maximum vertical direction size at the middle body of left and right directions, thereby guarantee to go up the durability of stopping part 34 and following stopping part 36.
In the present embodiment, make the size of fore-and-aft direction at 24,26 places of stopping part up and down of rubber annulus 12 bigger than the size of the fore-and-aft direction at main portion 30 places of rubber arm 14, thereby, rubber arm 14 will demonstrate soft spring performance vertically, and the stopping part up and down 24,26 of rubber annulus 12 will show enough durabilitys effectively.In addition, rubber annulus 12 can demonstrate the shape stability of enhancing.
In the present embodiment, silencer hanging bracket 10 is all only formed by rubber elastomer, thereby can easily make the silencer hanging bracket 10 with the weight that alleviates.
Fig. 4 A and Fig. 4 B illustrate selection embodiment of the present invention.In the present embodiment, rubber annulus 12 is provided with the limiting member 46 of ring-type near its outer peripheral portion, and this ring-type limiting member 46 is buried underground around whole circumference, with restriction rubber annulus 12, and vertically distortion when limiting above-mentioned stopping function.As ring-type limiting member 46, can use iron hoop or other becket, perhaps use the resin ring; Also can use the ring-type limiting member of making by metal filament or fabric 46.In the present embodiment, rubber annulus 12 suppress stopping function in the face of the part of rubber arm 14 effectively from the above and below time vertically distortion, this more effectively limits the excessive displacement vertically of rubber arm 14.
The embodiments of the invention that elaborate hereinbefore only are exemplary.Though in the above-described embodiments, when silencer hanging bracket is installed on the vehicle, first mounting hole 38 and a pair of second mounting hole 40 are positioned such that they are arranged to straight line on left and right directions, but in some cases, for example, can be that the center, hole that first mounting hole 38 and second mounting hole 40 are oriented to them vertically is positioned at ± scope of 6mm.Limiting member 46 can along the circumferential direction form partly.This feasible spring performance that can suitably adjust silencer hanging bracket perhaps can be strengthened silencer hanging bracket as selecting.In addition, should be appreciated that under situation about not departing from the scope of the present invention with aim, those skilled in the art can be to the various variations of the invention process, distortion and improvement.
