Description
Technical field
The invention belongs to field of automobile, specially refer to the connection structure of a kind of steering swivel system instrument beam and middle gangway-floor.
Background technology
Automobile steering system can guarantee that vehicle in the process of moving can be according to the wish of chaufeur, by control bearing circle realization Turning travel.Vehicle if bearing circle produces significantly shake, makes the driver produce tired and irritated mood in the process of moving easily, be unfavorable for driving safety, therefore in the vehicle R﹠D process, control the natural frequency of steering swivel system, reducing the shake of bearing circle, is an index of each strict control of car enterprise.
There is following problem usually in the connection structure of most steering swivel system instrument beam and middle gangway-floor: 1, part instrument beam supporting construction adopts asymmetrical design, cause easily middle passage supporting bracket rigidity lower, can the vibration shape of steering swivel system bearing circle be impacted in addition; 2, the instrument beam supporting construction adopts opening section, cause easily lateral rigidity a little less than; Consider the space arrangement requirement, can with the bending of instrument beam supporting bracket or certain angle that tilts, cause easily vertical stiffness not enough; 3, the restriction of the electrical parts such as CD and middle channel architecture is installed, and the upper end support interval of instrument beam supporting construction is wider, and the lower end support interval is narrower, cause easily supporting bracket root rigidity a little less than, affect the support effect of total.
Summary of the invention
The objective of the invention is to propose the connection structure of a kind of steering swivel system instrument beam and middle gangway-floor, with passage instrument cross beam support poor effect in solving, affect the drawback of steering swivel system modal stiffness.
The connection structure of steering swivel system instrument beam of the present invention and middle gangway-floor comprises steering swivel system instrument beam, middle gangway-floor, mounting bracket, upper bracket and U-shaped connection bracket, key is that described upper bracket comprises symmetrical left socle and right support, captiveing joint with the steering swivel system instrument beam in the top of described upper bracket, captives joint with middle gangway-floor by U-shaped connection bracket in the bottom; Described mounting bracket is welded between left socle and the right support.
Left socle and right support are symmetrical structure, can play the effect that adds persistent erection passage support stiffness, also can avoid because asymmetric structure design impacts the steering swivel system bearing circle vibration shape simultaneously.
Further, described left socle and right support are the closed cavity structure, can increase its side direction and torsional stiffness, avoid can not playing good supporting role to instrument beam because modal stiffness is lower.Also can avoid in addition annex or the shift handles such as CD electrical appliance kit with its connection, because support stiffness is not enough the customer be caused bad sensation.
Further, described left socle is parallel with right support, and the upper end support interval of instrument beam supporting construction is identical with the lower end support interval like this, can not cause supporting bracket root rigidity a little less than, and then affect the support effect of total.
Further, described mounting bracket is welded in the bending position of upper bracket, and its advantage is that bending position is bow-shaped structural spare, can provide stronger support stiffness for mounting bracket.
Further, described middle gangway-floor is provided with projection welding bolt, and described U-shaped connection bracket is connected with middle gangway-floor by described projection welding bolt; Described U-shaped connection bracket is perpendicular to middle gangway-floor.Can guarantee preferably like this root rigidity of connection bracket, on the base plate that can directly transmit in the vertical direction by the power of instrument beam transmission in addition, the bang path of power is simpler.And adopting projection welding bolt to connect U-shaped connection bracket and middle gangway-floor, mounting means is fairly simple, is convenient in the production realize.
Further, the both sides of described U-shaped connection bracket respectively are connected with one perpendicular to the L shaped brace panel of middle gangway-floor, the base of described L shaped brace panel and middle gangway-floor are connected and fixed by projection welding bolt, to strengthen further being connected between U-shaped connection bracket and the middle gangway-floor.
Further, described U-shaped connection bracket and L shaped brace panel are provided with flange, to strengthen the rigidity of U-shaped connection bracket and L shaped brace panel.
The connection structure of steering swivel system instrument beam of the present invention and middle gangway-floor can improve the support stiffness of connection bracket effectively, improve the mode of steering swivel system, can reduce preferably to shake up and down about bearing circle the peak value of response of vibration, increase the driver-operated comfort level.
