Abstract
The utility model relates to an intermediate shock absorber used in an automobile steering system, which is characterized in that the intermediate shock absorber is composed of pressure plates(1,5) and an intermediate friction plate(3); a castellated shaft (6) and a spline housing(7) are arranged respectively on the pressure plates; a connecting hole and a clearance hole(2) on the pressure plates are connected through a pin roll (4) with a cap; the pressure plates and the friction plate are in interference fit; the castellated shaft is connected with an internal spline housing of a universal joint fork which is arranged under an automobile steering column, and the spline housing (7) is connected to an external castellated shaft of the output shaft of a steering gear. The intermediate shock absorber has the advantages that the absorber can effectively reduce the shock of the steering system and ensure good superposition of the axial line of the steering column; a steering transmission mechanism swings evenly with even torque, which can effectively prevent the weakening of shock transfer onto the ground during the steering operation without impairing any performance of the steering system; meanwhile, the intermediate shock absorber amends the problem of difficult assembly caused by manufacturing errors on the steering column and a rack and pinion steering gear.
Description
Technical field:
The utility model relates to a kind of auto parts and components, particularly a kind of middle vibration damper that is used for automobile steering system.
Background technique:
The effect of wheel steering system is the wish change vehicle heading according to the driver, and in steering operation, the driver will pass through some information of being transmitted back by the road surface of steering system perception, in time changes steering operation.But the impact on road surface, especially bigger and continuous impact simultaneously,, steering system can cause driver fatigue, influence driver's normal driving, so must possess certain damping capacity, under the prerequisite that does not influence the manipulation of vehicle, effectively reduce driver fatigue.Existing a kind of in steering gear (steering column) increase the method for coupling drive, can reduce the vibration in turning to, as the disclosed technological scheme of Chinese patent CN01263587.1.But because of its complex structure,, cause steering column axis contact ratio poor again, the appearance of problem such as steering gear swing and moment are inhomogeneous, poor effect because foozle is inevitable.
Summary of the invention:
The purpose of this utility model is exactly for overcoming the defective of prior art, a kind of middle vibration damper that is used for automobile steering system that provides.
To achieve these goals, the present invention has adopted following technological scheme:
A kind of middle vibration damper that is used for automobile steering system, it is characterized in that: it is by being made up of the elastic-friction sheet of connecting between two block pressur plates and two block pressur plates, the axial direction of every block pressur plate connects a coupling shaft respectively, be respectively equipped with at least two attachment holes and at least two mesopores on every block pressur plate, attachment hole on every block pressur plate is relative with mesopore on another block pressur plate, every pair of relative attachment hole is connected with the bearing pin of mesopore by the band cap, make every block pressur plate and elastic-friction sheet produce interference fit, and the diameter of mesopore is greater than the diameter of bearing pin.Described elastic-friction sheet can adopt flexible resilient material, as rubber material, perhaps other synthetic fiber and chemical industry composite.
On the basis of technique scheme, also can with: set coupling shaft is a splined shaft on the block pressur plate, and set coupling shaft is a spline housing on another pressing plate; Described mesopore is designed to the half slot of opening; Bearing pin should make the relative deflection angle of two block pressur plates less than 2 ° with maximal clearance between the mesopore.Described splined shaft is used to connect the inner spline housing of steering column lower cardan fork; Spline housing is used to connect the male splined shaft structure of commutator input shaft.
The utility model advantage is: can effectively reduce the wheel steering system vibration, make steering column axis contact ratio good simultaneously, steering gear swing and moment are even, can effectively solve the decay of the road pavement transmitting vibrations in the Vehicular turn manipulation, do not influence simultaneously any steering system performance, can also improve simultaneously because the problems such as difficulty assembling that steering column and rack and pinion steering gear foozle cause.
For the utility model is described in further detail, provide an embodiment of the present utility model below.
Description of drawings:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is from overturn 180 ° stereogram of Fig. 1;
Fig. 3 is a sectional view of the present utility model;
Fig. 4 is the schematic representation of the relative deflection of two block pressur plates.
Embodiment:
Stereogram of the present utility model as shown in Figure 1 and Figure 2, sectional structure as shown in Figure 3, friction plate 3 and alignment pin 4 that vibration damper is made by left side pressing plate 1, right side pressing plate 5, middle flexible resilient damping material are formed.Flexible material can adopt general rubber material, perhaps other synthetic fiber and chemical industry composite.Pressing plate 1,5 and friction plate 3 are interference fit, the edge of pressing plate 1,5 is respectively equipped with the mesopore 2 of two attachment holes and two circular groove types, attachment hole on every block pressur plate is relative with the half gap hole 2 on another block pressur plate, every pair of relative attachment hole is connected with the bearing pin 4 of mesopore 2 by band cap 4a, make every block pressur plate and elastic-friction sheet 3 produce interference fit, and the diameter of mesopore 2 is greater than the diameter of bearing pin 4.Bearing pin 4 can adopt the two ends riveted joint when assembling, bearing pin, pressing plate and friction plate just are pressed together like this.In the steering operation process, frictional force is understood extrusion friction sheet generation resiliently deformable, but is out of shape in certain scope, otherwise will have influence on the rigidity of whole steering system, is out of shape too conference and causes the steering response of car load to lag behind.Vibration damper is realized by a limit structure, as shown in Figure 4, mesopore 2 openings of bearing pin 4 distances one side guide have a little gap when the neutral position, when steering column drives a side guide and bearing pin thereof input angle above one-sided 2 °, bearing pin 4 just contacts with mesopore 2 opposite sides, become and be rigidly connected,, can not impact in the using scope and turn to normally so only in very little input angle, influence steering system stiffness; And opposite, after bus or train route was subjected to road shocks, when reverse impact was passed to vibration damper, the overwhelming majority can be attenuated by flexible material deformation in positive and negative 2 ° scope, and it is level and smooth that the driver will feel on steering wheel.
