Description
Technical field
The invention belongs among automobile steering system technical field more particularly to a kind of bush type of duplex pull rod steering system
Plumbing arm assembly is primarily adapted for use in and solves the problems, such as that looseness easy to wear, use and maintenance is cumbersome, service life is short.
Background technique
Firstly, the intermediate plumbing arm bracket of automobile duplex pull rod steering system is set according to the relative positional relationship of plumbing arm and vehicle frame
Meter, after designing use, the height of plumbing arm is just difficult to adjust bracket；Plumbing arm support Design is not yet among the steerings of different automobile types
Equally, therefore, the versatility for turning to intermediate plumbing arm bracket is poor.Secondly, the general drop for turning to intermediate plumbing arm or length slightly have
Variation just need to redesign and be opened casting, and higher cost, versatility are also poor.Finally, pitman arm is movement the accurate transmission
Control unit, it is very high to clearance requirement to reach higher system stiffness and accurate course changing control；Currently used structure
Gapless adjustment link, gap guarantee difficult, during actual use often have the problem of pitman arm looseness；Looseness is latter
As can not eliminate, need replacing plumbing arm assembly to solve the problems, such as, therefore operation and maintenance higher cost.
Chinese patent, Authorization Notice No. CN202138410U, the utility model that authorized announcement date is on 2 8th, 2012
A kind of pitman arm assembly, including plumbing arm axis, bracket, plumbing arm are disclosed, plumbing arm includes plumbing arm body and its axle sleeve, the shape of plumbing arm body
Shape is symmetrical relative to the plane of symmetry formed by the upper end pin hole axis and plumbing arm axis axis, and plumbing arm body lower end head is ellipse for transverse direction
Circle, left and right is adjustable centered on long axis midpoint on the transverse on lower end head for the axis of lower end pin hole, outside plumbing arm axis
Control gasket is equipped at end stand rank, plumbing arm is assemblied in bracket end face by its axle sleeve and controls on the plumbing arm axis between gasket,
It is equipped with adjustment gasket between the end face and control gasket of axle sleeve, the gap of plumbing arm axial direction is 0.1 millimeter, plumbing arm body lower end pin hole head
For lateral ellipse, the center of circle of lower end pin hole can between each 10 millimeters of the left and right centered on long axis midpoint on the transverse
It adjusts.Although the utility model can adjust plumbing arm axial gap, it still has following defect：Plumbing arm axis in the utility model
It is directly to contact with plumbing arm, after plumbing arm assembly is used for a long time, plumbing arm and plumbing arm axis can generate abrasion, and adjusting pad piece is long-term in addition
Using also will appear damage, therefore, plumbing arm assembly can generate looseness because of abrasion, meanwhile, plumbing arm body is integrated with axle sleeve, so that
When axle sleeve damages, it is not easy to safeguard, service life is shorter.
