Abstract
The utility model discloses a disc brake steering axle assembly, including wheel hub brake disc assembly, interior foreign steamer hub bearing, knuckle, king pin, disc brake, front axle, knuckle arm, trapezoidal arm, drag link assembly, disc brake arranges directly over the king pin, relative axle assembly longitudinal plane symmetry. The disc brake is connected to two brake connecting plates symmetrically arranged on two sides of the steering knuckle main body. The tie rod assembly adopts a zero-drop tie rod assembly, namely, the ball center of the ball pin is positioned on the axis extension line of the tie rod. Two steering limit bolts are symmetrically arranged on the steering knuckle. The utility model discloses a disc brake arranges relative axle assembly longitudinal plane symmetry, and this is favorable to arranging of peripheral spare part, like drag link, shock absorber etc. is favorable to the stable performance of stopper braking performance, controls the knuckle and can use same blank, has improved the commonality of spare part, has reduced the development maintenance and the expense such as management of part variety and relevant mould. And the rigidity of the tie rod assembly is improved by adopting the zero-drop-difference tie rod assembly.
Description
Technical field
The utility model relates to a kind of plate disc brake steeraxle assembly, belongs to the steeraxle of steeraxle technical field, particularly plate disc brake.
Background technology
Plate disc brake more and more comes into one's own with its superior deceleration and stopping performance and good radiating condition at present, and heavy motor vehicle matees the more and more of plate disc brake.Along with domestic truck high-velocity stream constantly develops, the commercial vehicle/comm..vehicle speed of a motor vehicle is increasingly high, and it also is increasingly high that this deceleration and stopping performance to steeraxle requires, and this has facilitated the application of coupling plate disc brake steeraxle.But there is following problem in present structure:
1, the relative axle assembly longitudinal plane of the layout of drg is asymmetric, or before or after, cause the difficult arrangement of drag link or shock absorber.
2, the left and right blank of steering swivel is a mirror images, and the die cost input is many.
3, existing steeraxle intermediate rod has drop, and rigidity is poor, and is when using equal specification intermediate rod, flexible.
4, existing steeraxle is monolateral spacing.
Summary of the invention
The purpose of the utility model is to solve above deficiency, and preferred arrangement provides a kind of plate disc brake steeraxle assembly.
The technical scheme of the utility model: the plate disc brake steeraxle assembly of the utility model comprises wheel hub brake disk assembly, inside and outside hub bearing, steering swivel, stub, plate disc brake, front axle, track arm, tie rod arm, tie rod assembly; Its plate disc brake be arranged in stub directly over, relative axle assembly longitudinal plane symmetry.
Described plate disc brake is connected on two drg connecting panels of symmetry of steering swivel main body both sides, and three drg connecting bores respectively are set on two drg connecting panels.
Described tie rod assembly adopts withered and fallen poor tie rod assembly, and promptly the centre of sphere of ball pin is on the axis extended line of pull bar.
Described plate disc brake steeraxle assembly is symmetrical set two limiting steering bolts on steering swivel.
The advantage of the utility model:
1, plate disc brake is arranged in directly over the stub, and the axle assembly longitudinal plane is symmetrical relatively, and this helps the layout of peripheral parts, like drag link, shock absorber etc., helps the stable performance of drg deceleration and stopping performance.
2, drg connecting panel symmetry is located at the both sides of main body; The left and right steering swivel of this structure design is identical; Left and right sides steering swivel uses same blank; The problem wide in variety of avoiding the design of traditional mirror images to cause has improved the commonality of parts, has reduced the expenses such as development and maintenance and management of part kind and related die.
3, adopt withered and fallen poor tie rod assembly can improve the rigidity of tie rod assembly, avoid crooked.
4, traditional vehicle bridge is that interior wheel is spacing, and when the wheel right-hand turning, not spacing because of revolver, the rich moment of power steering can cause intermediate rod, drag link distortion.Inside and outsidely take turns simultaneously spacingly, can suppress the distortion of intermediate rod, drag link.

The specific embodiment
Fig. 1, Fig. 2 are the structural representations of the utility model:
The plate disc brake steeraxle assembly of the utility model comprises wheel hub brake disk assembly 1, inside and outside hub bearing 2, steering swivel 3, stub 4, plate disc brake 5, front axle 6, track arm 7, tie rod arm 8, tie rod assembly 9; Its plate disc brake 5 be arranged in stub 4 directly over, relative axle assembly longitudinal plane symmetry.The formed plane of two main pin axis about the assembly longitudinal plane promptly passes through.It is last that described plate disc brake 5 is connected two drg connecting panel 3a, the 3b of symmetry of steering swivel 3 main body both sides.Two drg connecting panel 3a, 3b be last respectively to be provided with three drg connecting bore 3c.On steering swivel 3, be symmetrical set two limiting steering bolt 3d, inside and outside wheel flutter can be simultaneously spacing.Originally be monolateral spacing.
Wheel hub brake disk assembly 1 is fixed on the steering swivel 3 through hub bearing 2; Plate disc brake 5 is fixed on 6 connecting bore 3c on the steering swivel 3 through 6 tie bolts; Steering swivel 3 forms pin with front axle 6 through stub 4 and is connected, and track arm 7 is connected with steering swivel 3 through bolt with tie rod arm 8.
Fig. 3 is the tie rod assembly structural representation: described tie rod assembly comprises joint 9a, the ball pin 9c in the joint 9a, pull bar 9b.Tie rod assembly 9 adopts withered and fallen poor tie rod assembly, and promptly the centre of sphere of ball pin 9c is on the axis extended line of pull bar 9b.Withered and fallen poor tie rod assembly can improve the rigidity of tie rod assembly.
