Abstract
The invention discloses a die-casting magnesium alloy steering column. The die-casting magnesium alloy steering column is tubular integrally; at a corresponding position where an adjusting mechanism of a steering wheel adjusting handle is mounted, the steering column is provided with an adjusting block; three sides of the adjusting block are separated from the steering column, and one side of the adjusting block is connected to the steering column. The steering column is formed by die casting once, the accuracy of forms and positions of parts is high, and as magnesium alloy is light in weight and high in damping performance, the requirements on light weight and energy absorption during head-on collision can be met; meanwhile, the steering column is simple in structure, and a crumple tube can be conveniently controlled without an additional mechanism to adjust the working height and the angle of a steering wheel.
Description
Technical field
The present invention relates to a kind of wheel steering tubing string, specifically a kind of diecast magnesium alloy steering column.
Background technology
Automobile turning pipe pillar assembly is as connecting steering handwheel and deflector to realize the vitals of chaufeur manipulation automobile, and its peaceful property and reliability seem particularly important.When automobile normal running; steering column must have enough strength and stiffness with while ensureing that normal direction of rotation power is transmitted, and also will guarantee to be installed on adjusting mechanism on Steering gear and safety guard (as shifter bar, combined switch etc.) normally works.When automobile generation head-on crash, steering column device can be compressed and be absorbed collision energy, to alleviate or to prevent the injury of chaufeur well.For improving the driving comfort performance of automobile, steering handwheel can realize the adjustment of its operating altitude and angle by the regulating mechanism on steering column.
Car steering tube column framing member is generally metal plate punching part and aluminum alloy die casting.Along with modern automobile steering swivel system turn to from hydraulic servo steering to electron servo, electric power steering (EPS), active steering and steering-by-wire (SBW) development, steering column structure and function are day by day complicated, are cast into the main forming technique of the steering tube cylinder for producing accurate labyrinth.Along with energy-conserving and environment-protective regulation increasingly stringent, the requirement of automotive light weight technology is also more and more higher, magnesium alloy is the lightest green metal structural materials, there is strength-to-density ratio and stiffness-to-density ratio is high, damping characteristics is good, and (damping coefficient is 15 times of aluminum alloy, 60 times of steel), be automobile lightweight, the ideal structure material reducing vibrating noise.The accuracy of form and position that employing diecast magnesium alloy steering column not only increases part is high, simultaneously because magnesium alloy light specific gravity, damping characteristics can meet well lightweight and the endergonic requirement of head-on crash.
Summary of the invention
Technical matters to be solved by this invention is to provide that a kind of adjustment structure is simple, weight-saving diecast magnesium alloy steering column.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of diecast magnesium alloy steering column, entirety is tubulose, in the corresponding position that the regulating mechanism of bearing circle regulating handle is installed, described steering column is provided with adjustment block, three limits of described adjustment block depart from steering column, are connected on steering column.
The inner side of described adjustment block is the arc-shaped matched with crumple tube-surface in steering column.
When the regulating mechanism work that steering column support is installed, the adjustment block of regulating mechanism compressing steering column, monolaterally to be connected with steering column owing to regulating block, appropriate elastic deformation will be produced under compressing, such adjustment block just moves in steering column, be close to the crumple pipe in steering column, the friction force between block and crumple pipe is regulated to increase, crumple pipe just can not move, thus on steering column support regulating mechanism adjustment under realize the adjustment of operating altitude to steering handwheel and angle.
Steering column of the present invention passes through one-step die casting, steering column of the present invention passes through one-step die casting, the accuracy of form and position of part is high, simultaneously because magnesium alloy light specific gravity, damping characteristics can meet well the requirement of lightweight and head-on crash energy-absorbing, simultaneously, this steering column structure is simple, just can control to realize the adjustment of operating altitude to steering handwheel and angle without the need to additional mechanism easily to crumple pipe.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is steering column structural representation of the present invention.
Fig. 2 regulates block position enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, diecast magnesium alloy steering column 1 entirety is tubulose, and the crumple pipe arranged in steering column 1, it is arranged on steering column support.Steering column support is provided with regulating mechanism, the adjustment of the operating altitude that regulating mechanism is realized steering handwheel to control crumple pipe by steering handwheel regulating handle and angle.
In the corresponding position that regulating mechanism is installed, described steering column 1 is provided with and regulates block 2, three limits of described adjustment block 2 depart from steering column, are connected on steering column.As can be seen from Figure 2, by stitching 3, adjustment block 2 and steering column 1 are departed from.
When the regulating mechanism work that steering column support is installed, the adjustment block 2 of regulating mechanism compressing steering column 1, monolaterally to link together with steering column 1 owing to regulating block 2, therefore appropriate deformation will be produced under compressing, such adjustment block 2 just moves in steering column 1, adjustment block 2 and the friction force be close between the interior crumple pipe arranged of steering column 1 increase, crumple pipe just can not move, thus on steering column support regulating mechanism adjustment under control crumple pipe and the adjustment of the operating altitude realized steering handwheel and angle.
For the ease of controlling crumple pipe by adjustment block 2, the inner side of described adjustment block 2 is the arc-shaped matched with crumple tube-surface in steering column 1.
Above-described embodiment does not limit the present invention in any way, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection scope of the present invention.
Claims (2)
