Abstract
The utility model relates to a steering straight pull bar arranged on a long front overhang chassis. In the prior art, during the steering process of a vehicle, the distortion of a conventional steering straight pull bar is larger due to the excessively long length of the pull bar, so that the chassis of the vehicle is unsteady and the steering performance of the vehicle is influenced. The steering straight pull bar provided by the utility model aims to solve the above problem in the prior art. According to the technical scheme of the utility model, the steering straight pull bar comprises a front straight pull bar and the front end of the front straight pull bar is hinged to the plumbing arm of a steering gear. The steering straight pull bar is characterized by also comprising a rear straight pull bar and an intermediate plumbing arm. The rear end of the rear straight pull bar is connected with the knuckle arm of a front axle. Both the rear end of the front straight pull bar and the front end of the rear straight pull bar are hinged to the intermediate plumbing arm. The intermediate plumbing arm is movably connected with a bearer assembly. The bearer assembly is arranged on the chassis. The steering straight pull bar has the advantages of simple structure, good steering stability, convenient operation, safety and reliability.
Description
Technical field
The utility model relates to a kind of automobile-used chassis, a kind of specifically steering drag link of growing on the front overhang chassis.
Background technology
For vehicle the front overhang long high floor tourist coach more than 10 meters, long-distance bus (being large and medium bus) or large truck etc.; The length of the steering drag link in the steering swivel system of traditional arrangement form can reach 1.6 meters to 1.8 meters; Find in the actual use that drag link length is above 1.5 meters; Can make the amount of deflection of steering drag link in steering procedure bigger than normal, make the distortion of drag link also can be bigger, cause the chassis unstable at steering procedure; Influence the turning efficiency requirement of car load, also can make the chassis can produce potential danger in the process of moving.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, and the steering drag link on a kind of simple in structure, steering stability good, operation is light, safe and reliable long front overhang chassis is provided.
Technical scheme comprises front end and the preceding drag link of deflector plumbing arm pivotally attached; Also include drag link and middle plumbing arm behind rear end and the propons joint arm bonded assembly; The front end of the rear end of drag link and back drag link is hinged on the middle plumbing arm before said; Plumbing arm flexibly connects with a seat assembly in the middle of said, and said seat assembly is installed on the chassis.
Said seat assembly comprises bearing and through the axle of bearing installation on bearing, said in the middle of the plumbing arm movable set on axle.
Beneficial effect:
The utility model structure is on the basis that traditional drag link is arranged, long drag link is become short forward and backward drag link, and through the middle plumbing arm that is movably connected on the seat assembly forward and backward drag link is linked into an integrated entity.This project organization has not only satisfied large and medium bus to turning to the designing requirement with drag link; Well avoided the long deflection deformation that causes of single straight pull bar; Reduce the deviation of the inharmonious track of divertical motion; What make the chassis turns to layout more simple, flexible, reliable, operate more lightly, has guaranteed steering swivel system stable, reliably on chassis.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of middle plumbing arm.
Fig. 3 is the cutaway view of Fig. 2.
Wherein, drag link, the middle plumbing arm of 3-, 4-prop up seat assembly, 4.1-bearing, 4.2-bearing, 4.3-axle, 5-deflector plumbing arm behind the preceding drag link of 1-, the 2-.
The specific embodiment
With reference to Fig. 1; Drag link 1, back drag link 2 and middle plumbing arm 3 before comprising, the front end and the deflector plumbing arm 5 of said preceding drag link 1 are hinged, and the rear end of back drag link 2 is connected with propons joint arm; The front end of the rear end of drag link 1 and back drag link 2 is hinged on the middle plumbing arm 3 before said; Plumbing arm 3 movable sets are on axle 4.3 in the middle of said, axle 4.3 through bearing 4.1 be installed in the fixing bearing 4.2 in chassis on, said bearing 4.1, bearing 4.2 and the axle 4.3 common bearing assemblies 4 of forming.
During work, drag link 1 swing before deflector drives through deflector plumbing arm 5, preceding drag link 1 affects middle plumbing arm 3 to rotate along axle 4.3, and drag link 2 is swung thereupon after the traction, and this tractive force is passed to propons joint arm the most at last, realizes the function that turns to of car load.
Claims (2)
1. the steering drag link on the long front overhang chassis; Comprise the preceding drag link of front end and deflector plumbing arm pivotally attached; It is characterized in that, also include drag link and middle plumbing arm behind rear end and the propons joint arm bonded assembly, said before the front end of rear end and back drag link of drag link be hinged in the middle of on the plumbing arm; Plumbing arm flexibly connects with a seat assembly in the middle of said, and said seat assembly is installed on the chassis.
2. the steering drag link on the long front overhang as claimed in claim 1 chassis is characterized in that, said seat assembly comprises bearing and through the axle of bearing installation on bearing, said in the middle of the plumbing arm movable set on axle.
