Description
Technical field
The utility model relates to the Independent Suspension field in Vehicle Engineering technology, is specially a kind of integral type lower cross arm that can be used for independent suspension.
Background technology
Along with the progress of auto manufacturing, people more and more pay attention to performances such as the travelling comfort of vehicle and driving safeties, and it is also more and more higher to its requirement.No matter traditional dependent suspension vehicle can not meet the requirement of people far away at road-holding property and driving safety.The exploitation of independent suspension vehicle becomes the inexorable trend of development of automobile.
In the prior art, the independent suspension structure type of vehicle is a lot, but includes at least one group of cross arm structure in its structure, and the version of its transverse arm adopted and arrangement directly affect manipulation stability, traveling comfort and the safety of car load.But traditional transverse arm is mostly the sectional construction that transverse arm adds strut, has difficult processing, assembling difficulty, location inaccuracy and change the defects such as difficulty.And the comparatively large and car load stability in motion of the noise that produces in the process of moving of car body is also had a greatly reduced quality, and badly influences traveling comfort and the safety of driving.
Utility model content
The technical matters that the utility model solves is to provide a kind of integral type lower cross arm, to solve the shortcoming in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of integral type lower cross arm, its lower cross arm body is formed in one, it comprises two support arms, article two, support arm forms a herringbone structure jointly, the free end of two support arms is respectively arranged with a transverse arm lining and a positive stop lug boss of beating, and linked together by screw thread pair and stub bulb at the coupling end of two support arms, and be connected with steering swivel by this stub bulb, described transverse arm lining both sides end face is provided with adjustment pad; Described positive stop lug boss of beating is arranged on a female splines seat, and this beats the boss plane of positive stop lug boss and the perforate direction of the internal splined hole in female splines seat parallel.
In the utility model, described female splines seat is connected with the torsion bar spring on car body independent suspension by spline fitted.
In the utility model, described support arm is also selected a mounting bracket of shock absorber is installed for mounting shock absorber.
In the utility model, described stub bulb is double-threaded screw stub bulb, the simple and relatively dismounting of its structure.
Beneficial effect: the utility model optimizes suspension frame structure, the basis simplifying its structure is convenient to dismounting and safeguards, simultaneously good mechanical property, its accurate positioning, driving noise are little, effectively can avoid constructive interference simultaneously, effectively improve underarm when automobile brake, the shortcoming of stressed difference.

Wherein: 1, lower cross arm body; 2, stub bulb; 3, transverse arm lining; 4, pad is regulated; 5, lower cross arm female splines seat; 6, to beat positive stop lug boss; 7, mounting bracket of shock absorber.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the preferred embodiment of a kind of integral type lower cross arm of Fig. 1, Fig. 2, Fig. 3, in the present embodiment, lower cross arm body 1 is formed in one, comprise two support arms, article two, support arm forms a herringbone structure jointly, the free end of its top support arm is provided with transverse arm lining 3, two side sections of this transverse arm lining 3 are provided with and regulate pad 4, transverse arm lining 3 both ends of the surface regulate pad 4 quantity to regulate the axial clearance of integral type lower cross arm and vehicle frame by increase and decrease, in order to improve underarm when automobile brake, the shortcoming of stressed difference; And the free end of bottom support arm is provided with lower cross arm female splines seat 5, be connected by the female splines in lower cross arm female splines seat 5 and torsion bar spring with vehicles suspension rate.
In addition, lower cross arm female splines seat 5 is provided with a positive stop lug boss 6 of beating, this positive stop lug boss 6 platform plane of beating is parallel with the perforate direction of lower cross arm female splines seat 5; In addition, top support arm is also provided with mounting bracket of shock absorber 7, when suspension frame structure is beated downwards, the bump rubber be arranged on vehicle frame contacts with positive stop lug boss 6 of beating and compresses, and organizes degree of skipping under suspension and loses efficacy; And mounting bracket of shock absorber 7 is convenient to the reasonable Arrangement of bumper, not only simplify suspension integral structure, avoid dependency structure interfere and also can be effectively cost-saving.
And a transverse arm inner threaded surface is provided with at the binding site place of two support arms, and be connected with stub bulb 2 by this transverse arm negative thread, then lock with jam nut, in the present embodiment, stub bulb 2 adopts double-threaded screw stub bulb to connect.Stub bulb 2 one end is threaded with lower cross arm body 1, and with jam nut locking, and other end screw thread is connected with steering swivel and supports steering swivel, effectively can simplify unitized construction, and improves its stability.
When the integral type lower cross arm of the present embodiment is used for torsion bar independent suspension system, upper and lower pair of transverse arm, steering swivel and vehicle frame form four-bar linkage, and the left and right sides is independent mutually, is independent of each other, and have accurate positioning and the advantage being easy to assemble.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
