Along with domestic continuous reinforcement, improvement and the user to limit for tonnage, overload improves constantly the requirement of conveying efficiency, and the market demand of two propons car of turning direction continues to increase.Adopt two propons to turn to, harmony when its wheel flutter rotates is most important, and front axle wheel must meet certain angle relation, otherwise will cause abnormal tyre wearing and tearing, driving running deviation, turns to the problems such as shimmy.Above-mentioned angle relation is mainly by kinematic optimal design, and follow-up manufacture, with in during to vehicle craspedodrome state the adjustment of two wheel flutter parallelism guarantee.The adjustment of the two propons car of turning direction front-wheel parallelism of domestic main flow mostly relies on the joint at rotation steering drag link two ends to change steering track rod entire length and realizes, when adjustment, steering drag link joint need be removed from plumbing arm, after adjustment completes, assemble, comfort feature is poor again, time-consuming longer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of steering front wheel mechanism for adjusting parallelism of the two propons car of turning direction that can adjust easily and fast wheel flutter parallelism.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A steering front wheel mechanism for adjusting parallelism for pair propons car of turning direction, comprising: adjust bar; Be arranged on respectively the adapter sleeve at described adjust bar two ends in adjustable depth of penetration mode; Be packed in respectively the steering track rod of described adapter sleeve, the other end.
Preferably, the two ends of described adjust bar have the outside thread that rotation direction is contrary, have the negative thread corresponding with described outside thread in described adapter sleeve, and this adapter sleeve is arranged on described adjust bar two ends in the mode being threaded.Employing this mounting means that is threaded, thus the depth of penetration adjustment steering front wheel parallelism of adapter sleeve just can be changed by rotation adjust bar, and operation is simple.
Preferably, described adjustment steering front wheel parallelism adapter sleeve, outer wall on be respectively arranged with locking hole, the screw bolt and nut for described adapter sleeve being locked to described adjust bar two ends is housed respectively on described locking hole.The setting of locking hole and the mode of locking thereof, can guarantee that adjust bar after adjusting and distance between adapter sleeve keep stablizing constant, guarantee to adjust the precision of steering front wheel parallelism.
Preferably, on described adjust bar, be provided with at least one string wrench clamp port, be convenient to rotate adjust bar by spanner.
Preferably, the described adapter sleeve respectively steering track rod corresponding with it is one-body molded, thereby has guaranteed the Rigidity and strength of adapter sleeve and steering track rod.
The utility model inserts the degree of depth of adjust bar by adjusting adapter sleeve can adjust steering front wheel parallelism as required, is easy to realize and detects and synchronize adjustment, has avoided dismounting steering drag link joint, has improved work efficiency.
Accompanying drawing explanation
The front view of the steering front wheel mechanism for adjusting parallelism of two propons car of turning direction that Fig. 1 provides for the utility model;
The partial view of the steering front wheel mechanism for adjusting parallelism of two propons car of turning direction that Fig. 2 provides for the utility model.
In figure: 1,5-steering track rod, 2,4-adapter sleeve, 3-adjust bar, 6-locking hole.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
A steering front wheel mechanism for adjusting parallelism for pair propons car of turning direction, as shown in Figure 1, comprising: adjust bar 3; Adapter sleeve 2,4; Steering track rod 1,5.
The two ends of adjust bar 3 have the outside thread that rotation direction is contrary, in adapter sleeve 2,4, there is the negative thread corresponding with described outside thread, adapter sleeve 2 is arranged on the left end of adjust bar 3 in the mode being threaded, adapter sleeve 4 is arranged on the right-hand member of adjust bar 3 in the mode being threaded.
In adapter sleeve 2, non-one end being connected with adjust bar 3 is fixed with steering track rod 1, and in adapter sleeve 4, non-one end being connected with adjust bar 3 is fixed with steering track rod 5.In the present embodiment, adapter sleeve 2 and steering track rod 1 are one-body molded, and adapter sleeve 4 and steering track rod 5 are one-body molded, thereby adopt the one-body molded Rigidity and strength that has guaranteed adapter sleeve and steering track rod.But this is not unique selection, those skilled in the art refill and are made into one after also adapter sleeve and steering track rod can being manufactured separately respectively, as adopted the mode being threaded or the mode pressing that the two is assembled.
As shown in Figure 2, on the outer wall of adapter sleeve 2,4, be respectively arranged with locking hole 6, the screw bolt and nut for adapter sleeve 2,4 being locked to described adjust bar 3 two ends is housed respectively on locking hole 6.The setting of locking hole and the mode of locking by bolt and nut thereof, can guarantee that adjust bar after adjusting and distance between adapter sleeve keep stablizing constant, guarantee to adjust the precision of steering front wheel parallelism.
On adjust bar 3, be provided with two string wrench clamp ports, be convenient to rotate adjust bar by spanner.
This regulating mechanism is connected in two front axles steering driving gears, as shown in Figure 1, regulates the distance between the A end of steering track rod 1 and the B end of steering track rod 5 by rotation adjust bar 3, promotes front-wheel and rotates, and adjusts steering front wheel parallelism.This mechanism is connected in two front axles steering driving gears, has steering drag link effect concurrently.
The occupation mode of this regulating mechanism is as follows:
When steering front wheel parallelism is regulated, unscrew adapter sleeve 2, on 4 locking holes 6, lock the bolt and nut of adjust bar 3, by spanner clamping in the spanner clamp port of adjust bar 3, rotation adjust bar 3, due to adjust bar 3 and adapter sleeve 2, 4 are threaded connection, and thread rotary orientation is contrary, when rotation adjust bar 3, the moving direction of adapter sleeve 2 and adapter sleeve 4 is contrary, and then cause respectively and adapter sleeve 2, 4 steering track rods that are fixedly mounted with 1, 5 A, the change of distance of B end, promote tyre rotation, play the parallelism effect that regulates, after adjusting finishes, the bolt and nut of fastening locking adjust bar 3.
