Background technology
For improving suitable property of taking advantage of of automobile product and road-holding property, modern automobile, particularly little, miniature car mostly disposes the preceding Biodge device of front wheel independent suspension.Adopting a kind of mode of wishbone-type independent suspension is to adopt coil spring or torsion bar spring and shock absorber to be contained in structure on underarm and the upper arm simultaneously.Upper and lower swing arm realizes the upper and lower displacement of suspension by ball end and vehicle frame and stub hinge joint and turns to.Another kind of mode also has and adopts horizontal leaf spring directly to replace down the structure of swing arm hinge joint on stub as " agricultural vehicle front wheel independent suspension driving and steering system " (China Patent No.: 98200331.5).Adopt first kind of structure, complex structure requires the lining at height and bulb place to wear and tear easily to the vehicle body setting accuracy, maintenance complexity and cost height.Adopt second kind of structure, the not high and vertical stiffness of front-wheel guiding accuracy a little less than, the shortcoming that front-wheel is easily shimmy.
Summary of the invention
The utility model provides a kind of automobile transverse plate spring independent suspension steeraxle, it will solve be have horizontal leaf spring independent suspension turn to the not high and vertical stiffness of sedan-chair motor turning bridge front-wheel guiding accuracy a little less than, the problem that front-wheel is easily shimmy.
In order to address the above problem, the structure of this automobile transverse plate spring independent suspension steeraxle and connect in the middle of include part same as the prior art: i.e. the horizontal end that is connected with leaf spring in vehicle frame bottom, the top of this vehicle frame is hinged with the Connection Block that turns to the pillar upper end by top link, described turning to outside the pillar is equipped with the rotating shaft tube by bearing carrier ring, one side of this rotating shaft tube is connected with the wheel mount pad by bearing, and described rotating shaft tube also is connected with the steering track rod that an end is contained on the described vehicle frame by articulated joint; In addition, unlike the prior art be: the bottom of described vehicle frame is connected with down an end of swing arm by jointed shaft, the other end of this time swing arm is connected with the described Connection Block of pillar lower end that turns to by jointed shaft, also be connected with a rocking arm in the swing arm down by jointed shaft, this rocking arm also is connected with the external part of described leaf spring and the lower end of a shock absorber by jointed shaft, and the upper end of this shock absorber is connected with described vehicle frame by jointed shaft.
In the such scheme, between the pin jointed end and jointed shaft of described leaf spring, between the pin jointed end and jointed shaft of described down swing arm, between described shock absorber and the jointed shaft rubber bush is housed all generally.In above-mentioned each scheme, described rotating shaft tube is to be connected with the described Connection Block of the upper and lower end of pillar that turns to respectively by the bearing that is contained in its upper/lower terminal.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, increased the bonded assembly frame mode of time swing arm, shock absorber and they and horizontal leaf spring external part in the scheme of the present utility model, and be furnished with rubber bush and rocking arm at the leaf spring two ends, make leaf spring Zhan Zhishi under condition of loading avoid movement interference with swing arm, the accurate guiding of in the time of can guaranteeing the pumping arm action campaign front-wheel being carried out, can solve effectively the not high and vertical stiffness of steeraxle front-wheel guiding accuracy a little less than, the problem that front-wheel is easily shimmy.
2, the rotating shaft tube by be contained in its upper/lower terminal bearing respectively with the upper and lower Connection Block bonded assembly structure that turns to pillar in, bearing wherein reduces maintenance cost by adopting in groups conical bearing state tender and can be convenient to maintenance and changing.
3, reliable operation, precision height.Rotating shaft tube and turn between the pillar installing tapered roller bearing in groups can guarantee that the rotating shaft tube has little friction force under condition of loading is to improve service life.Deflector and pull bar directly are contained on the vehicle frame of same fabricated section of upper and lower swing arm, and the steering trapezium that can more be optimized and guarantee cooresponding setting accuracy makes steering structure more reliable.The wheel mount pad is contained on the rotating shaft tube simultaneously, and at glancing impact, upper and lower swing arm provides longitudinal ligament simultaneously, and the stronger work of rigidity is more reliable.
