The technical scheme includes that the mounting bracket is fixed on a frame through a mounting hole through a bolt and a nut, and a rubber cushion is sleeved on the bolt. Through the installation the utility model discloses, enable the service environment on the car and satisfy the requirement in the aspect of the ECU controller vibrations, its simple structure, simple to operate, reliability are high, ECU controller long service life.
Description
Technical field
The utility model relates to a kind of vehicle shock-absorbing device, a kind of specifically shock absorption device of light-duty commercial vehicle/comm..vehicle ECU controller.
Background technology
Light-duty at home commercialization has at present begun to develop the light truck that reaches Europe three, Ou Si discharging, this light card is different from Europe two discharging vehicles, aspect engine control, increased the ECU controller, this ECU controller can be integrated on the engine body to be purchased integratively, but price is higher, makes manufacturing cost increase; Be cost-cutting, many producers directly purchase ECU separately, independently arrange on car load then, during installation.The ECU controller directly is connected with the vehicle frame rigidity, owing to can produce significantly vibrations during vehicle is exercised, these vibrations are directly conducted to the ECU controller by vehicle frame, the vibration environment of car load is that amplitude of vibration is when surpassing the ECU controller and limiting shock value, can have a strong impact on ECU controller normal operation and service life, reduce its functional reliability, the repair rate height, even bring potential safety hazard.
ECU controller shock value requires: when the ECU controller required frequency to be 300Hz, the power spectrum linear density was 0.6571 (m/s
2)
2/ Hz, when frequency was 1000Hz, the power spectrum linear density was 0.0596 (m/s
2)
2/ Hz.The ECU rigidity is connected on the car body, and the shock value that records on the ECU controller is: when frequency was 300Hz, the power spectrum linear density was 1.2248 (m/s
2)
2/ Hz, when frequency was 1000Hz, the power spectrum linear density was 2.1389 (m/s
2)
2/ Hz.Numerical value has exceeded the scope of fixed value.
Therefore, at this ECU controller that needs car load to arrange, need the installation shock absorption device of a kind of ECU controller of exploitation, having reduced the influence of car body vibrations, thereby make environment for use on the light-duty commercial vehicle/comm..vehicle satisfy the requirement of ECU controller vibrations aspect the ECU controller.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, provide a kind of simple in structure, easy for installation, reliability is high, can effectively reduce the car body vibrations influence to the ECU controller, prolongs the shock absorption device of the light-duty commercial vehicle/comm..vehicle ECU controller in its service life.
Technical scheme comprises mounting bracket, and described mounting bracket is fixed on the vehicle frame through bolt and nut by mounting hole, is with rubber mount on the described bolt.
Be with the T-shape rubber mount on the described bolt, be with " O " type rubber mount between mounting bracket and vehicle frame on the boss of described T-shape rubber mount hypomere,
Also be provided with center sleeve between described bolt and the T-shape rubber mount.
Also be with big pad on the bolt at described T-shape rubber mount two ends.
Described ECU controller is fixed on the mounting bracket, the mounting hole that the bolt lower end is passed on the mounting bracket passes vehicle frame again, use nut fastening then, suit rubber mount on bolt, make and separated by rubber mount between mounting bracket and the bolt, when cross-car or when vertically shaking, rubber mount can effectively reduce the conduction of vibrations.
Further, described rubber mount is preferably T-shape, be with " O " type rubber mount on its hypomere boss, mounting bracket also is enclosed within T " on the boss of type rubber mount hypomere, mounting bracket and vehicle frame are separated by " O " type rubber mount, avoid its direct contact; like this; when the car body porpoise, also can well reduce the vibrations of transmitting by vehicle frame, make that the ECU controller maintains in the scope of shock value requirement all the time on the mounting bracket.
By center sleeve bolt and T-shape rubber mount inwall are separated, passing through T " the big pad at type rubber mount two ends separates the head and the vehicle frame of rubber mount and bolt respectively; to reduce friction; the partial compression amount of balance rubber mount, improve T " type rubber mount and " O " type rubber soft service life.
The utility model makes that mounting bracket and vehicle frame are soft to be connected, the rubber mount shock-absorbing that the vibrations of car body are crossed by particular design, reduced the influence of car body vibrations to ECU controller on the mounting bracket, thereby make environment for use on the automobile satisfy the requirement of ECU controller vibrations aspect, it is simple in structure, easy for installation, reliability is high, ECU controller long service life.
Description of drawings
Fig. 1 is the utility model scheme of installation.
Fig. 2 is the right elevation of the present utility model that the ECU controller is housed.
Fig. 3 is T-shape rubber mount and the soft scheme of installation of " O " type rubber.
Among the figure, 1-nut, 2-spring shim, 3-flat shim, the big pad of 4-, 5-" O " type rubber mount, 6-center sleeve, 7-T-shape rubber mount, 7.1-boss, the big pad of 8-, 9-bolt, 10-vehicle frame, 11-mounting bracket, 12-mounting hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to accompanying drawing, mounting bracket 11 is provided with mounting hole 12, those skilled in the art can be according to position and the quantity of mounting bracket 11 with the requirement layout mounting hole 12 of vehicle frame 10 fixations, mounting bracket 11 tops have a mounting hole 12 in the present embodiment, the bottom has two mounting holes 12, and bolt 9 lower ends are passed behind mounting hole 12 and the vehicle frame 10 fastening by flat shim 3, spring shim 2 and nut 1 again.Be with center sleeve 6 on the described bolt 9, the center sleeve 6 outer T-shape rubber mounts 7 that are with, described mounting bracket 11 is enclosed within T " on the boss 7.1 of type rubber mount 7 hypomeres; also be with on the described boss 7.1 between mounting bracket 11 and vehicle frame 10 " O type rubber mount 5 also is with big pad 4,8 on the bolt 9 at T-shape rubber mount 7 two ends.Described center sleeve 6 can be selected metallic material for use.
During installation, the ECU controller is fixed on the mounting bracket 11, bolt 9 puts big pad 4 and a center sleeve 6 earlier, on center sleeve 6, put a T again " rubber mount 7 of type; after passing the mounting hole 12 of mounting bracket 11 then, put " O " type rubber mount 5 again, on bolt 9, put big pad 4 at last and contact with the vehicle frame 10 of car body again; bolt 9 passes cooresponding Kong Weihou on the vehicle frame 10, fix by flat shim 3, spring shim 2 and nut 1.
When producing vibrations in the car body traveling process, because T " rubber mount 7 of type and the effect of " O " type rubber mount 5; make that the vibrations of the whichever direction that vehicle frame 10 transmits all can be by T " rubber mount 7 and " O " type rubber mount 5 of type alleviate, thereby make original vehicle frame 10 become soft the connection with the rigidity company property of mounting bracket 11.Effectively reduced the influence of the vibrations of car body to the ECU controller.
The shock value that records on the ECU controller of the light-duty commercial vehicle/comm..vehicle that has installed the utility model shock absorption device additional is: when frequency was 300Hz, the power spectrum linear density was 0.4238 (m/s
2)
2/ Hz, when frequency was 1000Hz, the power spectrum linear density was 0.0325 (m/s
2)
2/ Hz meets the requirement of ECU controller shock value fully.
