The beach buggy steering swivel
Technical field
The utility model relates to a kind of beach buggy parts, especially beach buggy steering swivel.
Background technology
At present, general-duty beach buggy steering swivel is made of upper and lower rocking arm hinge component, steering swivel combination and steering swivel main shaft, the steering swivel main shaft is connected a side of steering swivel combination, the two ends up and down of steering swivel combination are set on the bearing pin of upper and lower rocking arm hinge component, and by the nut axial limiting.Its upper and lower rocking arm hinge component of the steering swivel of this structure is connected by the upper and lower rocking arm of ball end and beach buggy.Because upper and lower rocking arm hinge component is depended merely on steering swivel and is connected, and is open circuited between their axle center, front-wheel inwardly outwards rocks significantly when causing beach buggy to travel easily, the less stable of car load.In addition, upper and lower rocking arm turn to the arm of force too short, upper and lower rocking arm hinge component be subjected to force intensity little, can not get service life ensureing.
The utility model content
At the defective and the deficiency of prior art, the purpose of this utility model is to provide a kind of beach buggy steering swivel that front-wheel inwardly outwards rocks significantly can prevent effectively that car load from travelling the time.
The technical solution of the utility model is as follows: a kind of beach buggy steering swivel, comprise upper rocker arm hinge component, lower shake-changing arm hinge component, steering swivel combination and steering swivel main shaft, the installation journal stirrup of steering swivel combination upper/lower terminal is set on the bearing pin of upper and lower rocking arm hinge component, its key is: connect by connection pipe between the bearing pin of upper and lower rocking arm hinge component, described installation journal stirrup is spacing by the end face axial of connection pipe.
The upper/lower terminal of above-mentioned connection pipe is threaded with the bearing pin of upper and lower rocking arm hinge component respectively.
Upper and lower port at above-mentioned connection pipe is provided with position limiting convex ring, and the external diameter of this position limiting convex ring is greater than the diameter that suit hole on the journal stirrup is installed.
Adopt such scheme, owing to connect by connection pipe between the bearing pin of upper and lower rocking arm hinge component, their axle center links together, make the arm of force that turns to of the upper and lower rocking arm of beach buggy increase greatly, thereby overcome the disadvantage that front-wheel inwardly outwards rocked significantly when beach buggy travelled, greatly improved the stability of car load.The force intensity that is subjected to of upper and lower rocking arm hinge component increases longer service life simultaneously.
The beneficial effects of the utility model are: reasonable in design, be skillfully constructed, implement easily, it can effectively prevent from inwardly outwards to rock significantly when the beach buggy front-wheel from travelling, and has strengthened the stability of car load, is suitable for large-scale promotion application.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1: the utility model is made up of upper rocker arm hinge component 1, lower shake-changing arm hinge component 2, steering swivel combination 3 and steering swivel main shaft 4, steering swivel main shaft 4 is connected with a side of steering swivel combination 3, the installation journal stirrup 3a that steering swivel makes up 3 upper/lower terminals is set on the bearing pin 5 of upper and lower rocking arm hinge component 1,2, connect by connection pipe 6 between the bearing pin 5 of upper and lower rocking arm hinge component 1,2, described installation journal stirrup 3a is spacing by the end face axial of connection pipe 6.
Also can further find out from Fig. 1: the upper/lower terminal of connection pipe 6 is threaded with the bearing pin 5 of upper and lower rocking arm hinge component 1,2 respectively; Upper and lower port at connection pipe 6 is provided with position limiting convex ring 6a, and the external diameter of this position limiting convex ring 6a is greater than the diameter that journal stirrup 3a goes up the suit hole is installed.
