Abstract
The utility model discloses a front wheel support rocking arm mechanism for a four-wheel vehicle, which comprises a tyre support frame, a lower rocking arm, a steering rod and a shock absorber, wherein the upper and the lower ends of the tyre support frame are connected with an upper and the lower rocking arms respectively through screw bolts with spherical heads. The upper and the lower rocking arms are connected and fixed with lifting lugs on a vehicle frame. The steering rod is connected with the tyre support frame through the screw bolt with spherical head of the steering rod. The lower end of the shock absorber is fixed with the lower rocking arm through a screw bolt and the upper end is fixed with the lifting lug of the shock absorber on the vehicle frame through a screw bolt. The utility model overcomes the problems of an original mechanism and adopts a double rocking arm mechanism; thereby, the support, the steering and the shock absorption problems of front wheels of the four-wheel vehicle can be effectively improved; simultaneously, the service life of the support mechanism of the front wheels can be extended.
Description
Technical field
The utility model relates to the preceding wheeled support device of a kind of four-wheeled, and particularly a kind of four-wheeled front-wheel supports rocker arm body.
Background technology
Four-wheeled front-wheel supporting mechanism adopts a kind of structure that does not have upper rocker arm usually at present, such structure concentrates on the lower shake-changing arm front-wheel stress point, the stressed all directions that come from because of front-wheel, and stressed size variation amplitude span is big, frequency is high, can cause very big impulsive force to lower shake-changing arm, thereby make lower shake-changing arm bearing easily produce wearing and tearing, and then influence the support and the effectiveness in vibration suppression of lower shake-changing arm, and greatly reduce simultaneously its service life.In addition, the vibrations on the tire support that the structure of no upper rocker arm makes directly act on the deflecting bar, cause turning to of front-wheel dumb, have quickened the wearing and tearing of deflecting bar simultaneously, reduce its service life.In a word, solution support, the vibration damping that existing mechanism can't be good and turn to function and service life.
The utility model content
The purpose of this utility model is to provide the four-wheeled front-wheel of a kind of pair of rocking arm to support rocker arm body, actv. improve small four-wheel car front-wheel support, turn to and the vibration damping problem, prolong the service life of front-wheel supporting mechanism simultaneously.
A kind of four-wheeled front-wheel supports rocker arm body, comprises tire support, lower shake-changing arm, deflecting bar and bumper, and it is characterized in that: the two ends up and down of described tire support are connected with upper and lower rocking arm with ball stud respectively; Upper and lower rocking arm is connected and fixed by the hanger on rocker shaft and the vehicle frame; Described deflecting bar links to each other with tire support by the deflecting bar ball stud; The lower end of shock absorber and lower shake-changing arm are by bolt, and the upper end fixes by the shock absorber hanger on bolt and the vehicle frame.
The bulb position of above-mentioned deflecting bar ball stud is positioned at deflecting bar, and the support ball stud is positioned at the tire support two ends.
Tire support is connected with hanger on the vehicle frame by upper and lower rocking arm in the utility model, and rocking arm can be swung by rocker shaft on the one hand, and tire support can be moved up and down, and upper and lower rocking arm of while can play tire support and locate and directional tagging.Tire support with adopt ball stud during rocking arm is connected, the support ball stud is positioned at the tire support two ends, make tire support when being subjected to the impulse force of all directions, can not make tire support with producing rigid shock between the rocking arm, thereby actv. prolong the service life of part and the traveling comfort of chaufeur.Described shock absorber lower end and lower shake-changing arm are by bolted connection, and the shock absorber hanger on upper end and the vehicle frame has guaranteed its stressed and synchronism lower shake-changing arm, thereby played better buffer action also by bolted connection.Deflecting bar is connected with tire support by a ball stud; the bulb position of ball stud is installed in the deflecting bar, plays buffer action, thereby avoids the vibrations on the tire support to directly act on the deflecting bar; actv. has been protected deflecting bar, makes handling maneuver more flexible simultaneously.
Of the present utility model pair of rocker arm body, actv. improved the four-wheeled front-wheel support, turn to and the vibration damping problem, prolong the service life of front-wheel supporting mechanism simultaneously.

The specific embodiment
A kind of four-wheeled front-wheel supports rocker arm body, comprises tire support 6, upper rocker arm 1, deflecting bar 5 and bumper 2, and the two ends up and down of described tire support 6 are connected with upper and lower rocking arm 1,4 with ball stud 11 respectively; Upper and lower rocking arm 1,4 is connected and fixed by the hanger 8,9 on rocker shaft 3 and the vehicle frame, such structure rocking arm 1,4 on the one hand can be swung by rocker shaft 3, tire support 6 can be moved up and down, and 1,4 pairs of tire supports 6 of upper and lower rocking arm can play location and directional tagging simultaneously.Tire support 6 with adopt ball stud 11 during rocking arm is connected, and support ball stud 11 is positioned at tire support 6 two ends, make tire support 6 when being subjected to the impulse force of all directions, can not make tire support 6 with producing rigid shock between the rocking arm 1,4, thereby actv. prolong the service life of part and the traveling comfort of chaufeur.
Described deflecting bar 5 links to each other with tire support 6 by deflecting bar ball stud 12; the bulb position of ball stud 12 is installed in the deflecting bar 6; play buffer action; thereby avoid the vibrations on the tire support 6 to directly act on the deflecting bar 5; actv. has been protected deflecting bar 5, makes handling maneuver more flexible simultaneously.
The lower end of shock absorber 2 and lower shake-changing arm 4 are by bolt, and the upper end fixes by the shock absorber hanger 9 on bolt and the vehicle frame, thereby have guaranteed its stressed and synchronism lower shake-changing arm 4, play better buffer action.
Total the above, the utility model adopts two rocker arm bodies, actv. improved four-wheeled front-wheel 7 support, turn to and the vibration damping problem, prolong the service life of front-wheel 7 supporting mechanisms simultaneously.
