Abstract

The utility model discloses a front axle structure of a heavy truck. The front axle structure of the heavy truck is characterized in that an axle tube serves as a bearing portion of the front axle structure, the axle tube is an integrated square tube, master pin installing holes are machined in the two ends of the axle tube respectively, an upper leaf spring base and a lower leaf spring base are welded to the axle tube, steering knuckles are connected with the master pin installing holes of the axle tube through master pins respectively, and hub assemblies are fixed to the steering knuckles respectively. According to the structure, the front axle structure of the heavy truck has the advantages that the leaf spring bases are of a movable and adjustable structure, and thus the mold cost is reduced; due to the fact that after forming is accomplished, the amount of machining on the axle tube is small, the number of applied machining devices and the number of applied clamps are small, the machining cost is reduced, and mechanical performance of the axle tube is improved; the machining cycle and the delivery cycle are shortened; high-strength steel is not needed, and the material cost is reduced.

Description

A kind of front-axle structure of heavy duty truck
Technical field
The utility model relates to production and the manufacture of heavy duty truck, particularly a kind of front-axle structure of heavy duty truck.
Background technology
Existing heavy duty truck propons is comprised of parts such as H-girder, steering swivel, brake wheel, wheel hub, drgs conventionally.Two steering swivels are contained in respectively the two ends of H-girder, and wheel hub is by inside and outside two bearing carrier rings on steering swivel, and brake wheel is connected with wheel hub by wheel bolt.
Propons bearing part is generally structural I-beam at present, its forming process is mostly forging molding, directly punching or milling face conventionally in the junction of propons and other positions of car load on H-girder, easily produces fabrication stress, and H-girder body intensity is weakened to a certain extent to some extent; More because of procedure of processing, required fixture and Fabricating machinery drop into larger, and tooling cost is higher, because the reasons in structure of H-girder, for guaranteeing its intensity under respective loads, needs to adopt the higher material of quality, in material cost, also increase accordingly simultaneously.
For the problems referred to above, the cost and the processing capacity that when improving bearing part intensity, reduce axle assembly are the problems that prior art need to solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of front-axle structure of heavy duty truck, to reach the object that reduces cost and the processing capacity of axle assembly when improving bearing part intensity.
For achieving the above object, the technical solution of the utility model is that a kind of front-axle structure of heavy duty truck, is characterized in that: the bearing part of described front-axle structure adopts the central siphon of integral type square tube form, and two ends are processed with stub mounting hole; On central siphon, be welded with respectively spring block and lower spring block; Steering swivel is connected with the stub mounting hole of central siphon by stub, and Hub assembly is fixed on steering swivel, thereby forms whole front-axle structure.
Described steering swivel is connected with tie rod assembly by spindle arm.
Described central siphon inside is hollow structure, and central siphon adopts round steel pipe machine-shaping, and two ends adopt and are squeezed into solid construction.
On described upper spring block and lower spring block, be respectively equipped with leaf spring knock hole, can be according to main engine plants' vehicle demand option board spring abutment position.
Described steering swivel is provided with air chamber.
Described spindle arm is Forging Parts, by two flange face hexagonal bar irons, is connected with steering swivel; Other end taper hole place is connected with steering drag link bulb by draw-in groove nut.
A front-axle structure for heavy duty truck, owing to adopting above-mentioned structure, the utility model has the advantage of: 1, this structural slab spring abutment employing activity, adjustable structure, saved die cost; 2, less to central siphon processing after moulding, Fabricating machinery and fixture application are less, have saved tooling cost, and have improved the mechanical characteristics of central siphon; 3, process-cycle and delivery cycle have been shortened; 4, without selecting high strength steel, saved Master Cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structural representation of the front-axle structure of a kind of heavy duty truck of the utility model;
Fig. 2 is the top structure schematic diagram of the front-axle structure of a kind of heavy duty truck of the utility model;
Fig. 3 is the structural representation of the front-axle structure central siphon of a kind of heavy duty truck of the utility model;
In Fig. 1-3,1, Hub assembly; 2, vertical pulling lever arm; 3, central siphon; 4, upper spring block; 5, lower spring block; 6, air chamber; 7, steering swivel; 8, spindle arm; 9, tie rod assembly, 10, stub mounting hole.
The specific embodiment
As shown in Figure 1, the utility model bearing part adopts integral type square tube form, and central siphon 3 inside are hollow structure, and central siphon is adopted 3 and used round steel pipe machine-shaping, and two ends adopt and are squeezed into solid construction, then at two ends solid section processing stub mounting hole 10.
On central siphon 3 tops, adopt two free-standing spring blocks, spring block is provided with leaf spring knock hole, can be according to main engine plants' vehicle demand option board spring abutment position, and after adjust position, employing welding manner is welded on central siphon 3 tops by upper spring block 4.The same absolute version that adopts of lower spring block 5 needs to process four U-bolt mounting holes on its position, relatively goes up spring block 4 and adjusts position, is welded on central siphon 3 lower surfaces.
Upper spring block 4, lower spring block 5 are welded on central siphon 3, and steering swivel 7 is connected with central siphon 3 by stub, and Hub assembly 1 is fixed on steering swivel 7 by bearing and jam nut, and tie rod assembly 9 is connected with steering swivel 7 by spindle arm 8 with steering swivel 7.Steering swivel 7 is provided with air chamber 6.
The utility model adopts rectangular tube structural I-beam, in this structure central siphon performance, have that rigidity is high, bending resistance anti-twisting property is strong, in same load situation, be out of shape the advantages such as little, in structure and manufacturing cost, there is the advantages such as flat appearance, smooth, attractive in appearance, easy to process, low cost of manufacture.In addition spring block adopts and is welded on separately structure on central siphon, relevant U-bolt mounting hole and all perforates on spring block of leaf spring dowel hole, and this structure is different from the perforate on H-girder body of common H-girder, is easy to guarantee the intensity of H-girder body.
Spring block employing activity of the present utility model, adjustable structure, can carry out the adjustment of corresponding position to the demand of different leaf spring width between centerss according to main engine plants, without because of the different die sinkings again of leaf spring width between centers, therefore saved die cost; Central siphon 3 is integral forming structure, and less to central siphon 3 processing after moulding, Fabricating machinery and fixture application are less, have saved tooling cost, and have improved the mechanical characteristics of central siphon; In the course of processing, grinding tool application is less, shortened process-cycle and delivery cycle; Rhs-structure carrying is relatively high, without selecting high strength steel, thereby has saved Master Cost.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
