Abstract
The utility model discloses a steering knuckle for a disc-type brake front axle of a medium-duty truck. The steering knuckle comprises a main body, a steering-axle upper connecting plate, a steering-axle lower connecting plate, a connecting shaft, and two braking device connecting plates, wherein the steering-axle upper connecting plate and the steering-axle lower connecting plate are connected with the main body; the connecting shaft is used for fixing a braking disc; the steering-axle upper connecting plate and the steering-axle lower connecting plate are respectively provided with a main pin hole; the steering-axle upper connecting plate is provided with an upper steering knuckle arm installation joint; the steering-axle lower connecting plate is provided with a lower steering knuckle arm installation joint; and the two braking device connecting plates are respectively arranged at the top part of the main body and are arranged symmetrically to the main pin holes. The steering knuckle disclosed by the utility model has the advantages that the layout of a compound air chamber is convenient, and the layout space of the whole truck is larger; the structure stress is more reasonable; the weight of a single piece is reduced, and the production cost and the use cost are reduced; and the service life of the front axle is prolonged.
Description
Technical field
The utility model relates to automotive field, relates in particular to a kind of steering swivel new construction of medium and heavy automobile disk-type braking propons.
Background technology
Existing slewing journal structure can only adopt single cavity gas chamber when arranging air chamber, if arrange compound air chamber, then the car load arrangement space is not enough, has perhaps increased the weight of car load, and air chamber is arranged complicated, is unfavorable for that automobile energy-saving reduces discharging the development of new thought.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved in the utility model is, provide a kind of under the situation that does not change original material, by changing the structure of front axle steering knuckle, increase the car load space and arrange, use CAE software the steering swivel new construction to be analyzed implementation structure optimization, and fall and heavily fall cost, thereby improve a kind of medium and heavy automobile disk-type braking propons steering swivel in automobile and axle assembly service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of medium and heavy automobile disk-type braking propons steering swivel, comprise main body, the upper and lower connecting panel of the steeraxle that is connected with main body, fixedly adapter shaft, the two drg connecting panels of brake disc, be equipped with kingpin bore at the upper and lower connecting panel of steeraxle, described steeraxle upper junction plate is provided with the track arm mounting interface, the steeraxle lower connecting plate is provided with down the track arm mounting interface, described two drg connecting panels are located at the top of main body respectively, and are symmetrical arranged with kingpin bore.
Above-mentioned medium and heavy automobile disk-type braking propons steering swivel is equipped with the drg connecting bore at two drg connecting panels.
Above-mentioned medium and heavy automobile disk-type braking propons steering swivel offers the limiting steering bolt hole in main body.
The advantage of the utility model card slot type New Brake is: this new construction has improved the steering swivel space and has arranged, adopts the drg overhead type, and convenient compound air chamber is arranged, makes the car load arrangement space bigger; Improve structure design, made the steering swivel more reasonable stress, improved the service life of automobile front axle, reduced production and use cost.
