Abstract
The present invention relates to a few font cushioning support-saddle of a kind of armored vehicle diesel engine, comprise main damper 3, base plate 6, also comprise a few font support 2, lower a few font support 4, nut 1, lower tie bolt 5, upper tie bolt 7 and bolt of rear end plate 8; Main damper 3 is fixedly connected with upper a few font support 2 by nut 1; Main damper 3 is fixedly connected with lower a few font support 4 by upper tie bolt 7; Upper a few font support 2 is connected with diesel engine by bolt of rear end plate 8; Lower a few font support 4 is fixedly connected with base plate 6 by lower tie bolt 5.The buffer structure adopting main damper 3, upper a few font support 5 and lower a few font support 4 jointly to form can suppress formant effectively, has good anti-vibration and shock effect; Upper a few font support 2 has inhibiting device, and the diesel engine amplitude that causes of preventing from transshipping is excessive; By adopting a few font cushioning support-saddle structure, making the accurate positioning of support, increasing pooling feature better, improve complete machine functional reliability.
Description
Technical field
The invention belongs to armored vehicle diesel engine technical field, be specifically related to a kind of cushioning support-saddle of diesel engine.
Background technology
The combustion pressure of diesel engine, reciprocal inertia force and bank moment all can make diesel engine produce larger vibration, vibrate and pass to vehicle chassis by supporting, cause Vehicular vibration.For armored vehicle diesel engine, because condition of road surface when it uses is severe, because the vibration of the generation of jolting of vehicle is especially serious.Vibration directly has influence on the functional reliability of diesel engine and inner high precision electronic equipment thereof, and the traveling comfort of vehicle and durability.In addition, armored vehicle produces powerful impact strength instantaneously when firing, and passes to diesel engine, can cause damage, directly have influence on the life and reliability of diesel engine to diesel engine and other ancillary system by supporting.
Application number be 201210405172.8 application discloses a kind of engine-mounting bracket, only rise to support and without the shortcoming of cushioning effect for solving available engine erection support, comprise two pieces of vertical stay bearing plates, the horizontal fixed plate being fixedly connected with two stay bearing plates is provided with in the upper end of stay bearing plate, stay bearing plate epimere is connecting portion, the hypomere of stay bearing plate is the support portion for being connected with support platform, the junction of connecting portion and support portion is provided with at least two rows, the long lumbar hole of the arrangement in upside-down trapezoid, the waist length direction of long lumbar hole is horizontal direction, and the long lumbar hole in the vertical direction of upper row and lower row staggers mutually.This invention arranges some holes by regular on the supporting plate, weakens stay bearing plate rigidity, changes the flow direction in stay bearing plate bearing capacity direction, becomes strain energy plate, and air flue relaxes the secondary shock-absorbing function of impact, damping vibrations.
But there is damping effect difference in the erection support of prior art, when engine vibration is larger bearing poor reliability, easily by defects such as conquassation.
Summary of the invention
For the shock resistance demand of armored vehicle diesel engine, a few font cushioning support-saddle of a kind of armored vehicle diesel engine is proposed.
The technical solution adopted in the present invention is: a few font cushioning support-saddle of a kind of armored vehicle diesel engine, comprises main damper 3, base plate 6; Also comprise a few font support 2, lower a few font support 4, nut 1, lower tie bolt 5, upper tie bolt 7 and bolt of rear end plate 8; Main damper 3 is fixedly connected with upper a few font support 2 by nut 1; Main damper 3 is fixedly connected with lower a few font support 4 by upper tie bolt 7; Upper a few font support 2 is connected with diesel engine by bolt of rear end plate 8; Lower a few font support 4 is fixedly connected with base plate 6 by lower tie bolt 5.
Beneficial effect of the present invention: adopt main damper and a few font buffer structure to coordinate and effectively can suppress formant, there is good anti-vibration and shock effect.In addition, by adopting a few font cushioning support-saddle structure, making the support of complete machine realize upper and lower a few character form structure, making the accurate positioning of support, better increase pooling feature, improve complete machine functional reliability.
Accompanying drawing explanation
Fig. 1 is a few font cushioning support-saddle of a kind of diesel engine structural representation.
Tie bolt 8 bolt of rear end plate 9 position limiting structure on a few font support 3 main damper 4 times a few font supports 5 times tie bolt 6 base plates 7 on 1 nut 2
Detailed description of the invention
A few font cushioning support-saddle of a kind of armored vehicle diesel engine, comprises main damper 3, base plate 6; Also comprise a few font support 2, lower a few font support 4, nut 1, lower tie bolt 5, upper tie bolt 7 and bolt of rear end plate 8; Main damper 3 is fixedly connected with upper a few font support 2 by nut 1; Main damper 3 is fixedly connected with lower a few font support 4 by upper tie bolt 7; Upper a few font support 2 is connected with diesel engine by bolt of rear end plate 8; Lower a few font support 4 is fixedly connected with base plate 6 by lower tie bolt 5.
After diesel engine is installed to piggyback pod, when diesel engine faces larger vibration, except main damper, upper a few font support and lower a few font support all can be out of shape absorbing vibrational energy, reduce vibratory impulse, strengthen damping effect, thus improve traveling comfort and the durability of vehicle.
After diesel engine is installed to piggyback pod, a few font support and lower a few font deformation of timbering absorbing vibrational energy in dependence, buffering vibration, diesel engine produces certain displacement with the distortion of lower a few font support relative to piggyback pod with upper a few font support, but the intake and exhaust pipe interface of diesel engine is fixing relative to piggyback pod, once the distortion of upper a few font support and lower a few font support is excessive, the connecting portion of diesel engine and intake and exhaust pipeline must be caused to produce and to misplace, the problem that intake and exhaust are leaked occurs.
For solving upper a few font support and the excessive problem causing intake and exhaust to be leaked of lower a few font support sex change, preferably position limiting structure 9 is set at upper a few font support 2.
After preferably upper a few font support 2 is connected with main damper 3, the spacing gap that position limiting structure 9 and main damper 3 are formed is 3mm.Effectively can ensure that diesel vibration amplitude is less than 5mm, meets the seal request of diesel engine and air inlet system and exhaust system connection structure, ensure that air inlet-outlet pipe can not be revealed.
Preferably upper a few font support 2 adopts QT450 to cast formation; Lower a few font support 4 adopts sheet steel stamped, and thickness is 6mm, and height 67mm, hardness 28 ~ 33HRC after heat treatment, advantage is that cost is low, good damping effect.
