Description
Technical field
The utility model relates to a kind of auto parts and components, especially relates to a kind of supporting structure of tear-away formula subframe.
Background technology
Along with popularizing of automobile, it is more and more frequent that traffic accident takes place, and improves automobile design, and the safety performance that improves automobile becomes more and more important problem.Existing automobile mostly adopts the engine behind front wheel structure; The dynamic assembly of this type automobile comprise driving engine, change-speed box and with side power transmission member such as change-speed box bonded assembly transmission shaft; Driving engine in the dynamic assembly and change-speed box generally are arranged on the subframe through suspending; Like notification number be: the automobile accessory frame connection structure that the Chinese utility model of CN201009934Y provides, the automobile accessory frame connection structure is through sheet auxiliary connection frame assembly and vehicle body in curved boom outer plate and the curved boom, and sheet is as a whole in curved boom outer plate and the curved boom; And run through whole subframe, and stretch out and body contact in the subframe two sides.This utility model is connected with chassis runner through the support on the subframe; Because dynamic assembly is arranged on the subframe through suspending, thereby dynamic assembly can only move backward and can not sink, when in automobile is being run at high speed process, head-on crash taking place; Dynamic assembly will be moved rapidly by the extruding of impact force backward; After the dynamic assembly that moves usually can directly strike dash shield because dynamic assembly can not sink, thus after the dynamic assembly that moves too big to the impulsive force of dash shield; Cause dash shield intrusion amount to exceed standard, easily chaufeur in the car and occupant are damaged.
Summary of the invention
The utility model mainly be to existing subframe existing when the automobile central collision subframe can not sink; Cause the dynamic assembly on the subframe too big to the impulsive force of dash shield; The problem of harm chaufeur and occupant's personal safety; Subframe can separate with chassis runner when a kind of automobile central collision was provided, and makes the impact direction of dynamic assembly change and the impulsive force of dash shield is diminished, and can effectively protect the supporting structure of chaufeur and occupant's tear-away formula subframe.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: a kind of supporting structure of tear-away formula subframe; Comprise be arranged on the subframe both sides and lay respectively at subframe and chassis runner between connecting panel; Connecting panel is provided with mounting hole; Connecting panel is connected with chassis runner through the binding bolt that passes mounting hole; Also be provided with on the described connecting panel can make binding bolt through and the hole that comes off that breaks away from, the described hole that comes off is positioned at the direction setting towards headstock of mounting hole, described hole and the mounting hole of coming off is connected as a single entity.The both sides of existing automobile accessory frame are provided with and chassis runner bonded assembly connecting panel; Connecting panel is fixed through binding bolt and chassis runner; Subframe is fixed on the chassis runner through the right connecting panel that is provided with of a first from left, and after the automobile central collision, dynamic assembly will be moved backward and transmission shaft can collide subframe; This moment, subframe and support still were connected with automobile longitudinal girder through bolt; Dynamic assembly on the subframe causes greater impact over against dash shield and to dash shield, and the intrusion amount of dash shield is excessive, easily chaufeur in the car and occupant is damaged; The utility model has been set up one on adapter plate can make the come off hole of binding bolt through also breaking away from; Come off hole and mounting hole is connected as a single entity, and this hole size that comes off should be greater than the nut of binding bolt, after transmission shaft collides subframe; The subframe extrusion will make binding bolt clamp-on come off hole and the disengaging hole that comes off from mounting hole; Subframe separates in the junction with chassis runner like this, receives self gravitation to influence subframe and dynamic assembly will together sink, and the impact direction of the dynamic assembly of sinking departs from dash shield by becoming over against dash shield under oblique; The impact direction of dynamic assembly changes; Impulsive force to dash shield reduces, and it is little that dash shield is invaded quantitative change, so the utility model can effectively be protected chaufeur and passenger's personal safety.After the automobile central collision, transmission shaft collision subframe, subframe are impacted crimp backward can take place; For binding bolt can be clamp-oned in the hole that comes off, should make the hole that comes off be arranged at the direction towards headstock of mounting hole, if be reference with the vehicle complete vehicle system of axes; The hole that comes off is positioned at the place ahead of mounting hole; Promptly towards the direction of headstock, after subframe squinted backward like this, binding bolt can be clamp-oned in the hole that comes off smoothly.
As preferably, the described hole that comes off is the outward extending sector notch along the mounting hole center.Come off the hole for along the mounting hole center outward extending sector notch; Then come off the hole for being to stretch basic point with the mounting hole, and the sector structure of outside stretching, extension is far away more from mounting hole gradually; The expanded area in hole of coming off is big more; Being the fan-shaped hole size that comes off should be greater than the nut of binding bolt, and after transmission shaft collided subframe like this, binding bolt can be clamp-oned and break away from the hole and the hole that comes off.
As preferably, 0.6～0.9 times of the aperture that the described width that comes off hole and mounting hole junction is a mounting hole.Coming off the width of hole and mounting hole junction should be less than the aperture of mounting hole; This width is 0.6～0.9 times of mounting hole aperture, satisfies operating needs, and the junction of fan-shaped come off hole and mounting hole forms the turning; Can play the effect of placing restrictions on to binding bolt; Prevent that in the automobile bumpiness process, binding bolt slips in the hole that comes off with body oscillating, influences the automobile normal driving.
As preferably, the described hole that comes off is positioned at the diagonal upward direction setting of mounting hole.The hole that comes off is arranged at the oblique upper of mounting hole, helps the binding bolt hole that comes off, and binding bolt is blocked in the upper edge in the hole that prevents to come off, and causes binding bolt can not break away from the hole that comes off.
Therefore; The beneficial effect of the utility model is: increased the groove that comes off in the binding bolt junction of subframe and longeron; Binding bolt can break away from the hole that comes off during the automobile central collision; Make dynamic assembly sink, reduced the impact of dynamic assembly, can effectively protect chaufeur and passenger's personal safety dash shield.
