Abstract
The utility model discloses a special disc type steering gear of a tricycle. The special disc type steering gear of the tricycle comprises a shell, a gear, a rack and a steering arm, wherein the gear and the rack are mounted in the shell and meshed with each other; the steering arm is connected with one end of the rack; a clearance compensation device is mounted at the bottom of the rack; and the rack is connected with the steering arm through two universal ball heads. The clearance compensation device is mounted additionally, so that the tricycle operates stably and reliably, fault rate is reduced and service life is prolonged. In addition, the rack is connected with the steering arm through two universal ball heads, so that the steering arm is capable of swing left and right in an angle of 70 degrees and the tricycle can steer in a large angle; and a rack lining is arranged, so that the rack moves on one straight line all the time.
Description
Technical field
The utility model relates to deflector, refers to especially the deflector of a kind of three-wheel vehicle disc type.
Background technology
The deflector of existing three-wheel vehicle disc type is the motion of rack-and-gear rocker-type, gear makes wheel and rack interlock by fixed pedestal, contact surface between tooth bar and fixed pedestal is little, in the process of motion, easily there is mechanical wear, due to Non-clearance automatic compensation mechanism, therefore in use fault is many in this deflector, and the life-span is short, affects traffic safety.In addition, existing three-wheel vehicle disc type steering gear rack adopts a universal ball end to be connected with spindle arm, and three-wheel vehicle, in the process turning to, can not be realized the requirement that turns to of wide-angle, more inconvenient.
Utility model content
The utility model proposes the deflector of a kind of three-wheel vehicle disc type, solved the wearing and tearing of prior art middle rack and do not there is the technical matters that backlash compensation and three-wheel vehicle can not wide-angle turn to.
The technical solution of the utility model is achieved in that the deflector of a kind of three-wheel vehicle disc type, the spindle arm that comprises housing, is arranged in housing the gear of interlock and tooth bar mutually and is connected with one end of tooth bar, the bottom of described tooth bar is provided with blank compensation apparatus, between described tooth bar and spindle arm, adopts two universal ball ends to be connected.
Wherein, described blank compensation apparatus comprises the spring that the limit base that is connected with tooth bar and one end are connected with limit base, and the other end of described spring is connected with screw rod, and described screw rod adopts jam nut locking.
Particularly, the export-oriented bulb that described two multi-directional ball are wherein connected with described tooth bar is liner ball head, and the export-oriented bulb being connected with described spindle arm is 90 degree bulbs.
Further, between described housing and tooth bar, rack bush is installed.
Further, described rack bush is double focusing ammoniacum laminar texture.
Compared with prior art, the beneficial effects of the utility model are: be provided with blank compensation apparatus, three-wheel vehicle is operated steadily reliably, reduced fault rate, extended service life.In addition, between tooth bar and spindle arm, adopt two universal ball ends to be connected, realize the spindle arm angle that swings and can reach 70 degree, realize three-wheel vehicle wide-angle and turn to.And the setting of rack bush makes tooth bar keep motion point-blank.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, the deflector of a kind of three-wheel vehicle disc type, the gear 3 that comprise housing 1, is arranged on housing 1 interior mutual interlock and tooth bar 2 and the spindle arm 4 being connected with one end of tooth bar 2, the bottom of described tooth bar 2 is provided with blank compensation apparatus, between described tooth bar 2 and spindle arm 4, adopts two universal ball ends to be connected.The utility model is provided with blank compensation apparatus, and three-wheel vehicle is operated steadily reliably, has reduced fault rate, has extended service life.In addition, between tooth bar 2 and spindle arm 4, adopt two universal ball ends to be connected, spindle arm 4 angle that swings can reach 70 degree, realizes three-wheel vehicle wide-angle and turns to.And the setting of rack bush 5 makes tooth bar 2 keep motion point-blank.
Wherein, described blank compensation apparatus comprises the spring 9 that the limit base 8 that is connected with tooth bar 2 and one end are connected with limit base 8, and the other end of described spring 9 is connected with screw rod 10, and described screw rod 10 adopts jam nuts 11 lockings.In the process of using, adjusting screw(rod) 10 after wearing and tearing between limit base 8 and tooth bar 2, makes limit base 8 be held against and be connected with tooth bar 2 by spring 9, reaches the object of automatically carrying out backlash compensation, then locks jam nut 11.Described screw rod 10 is the adjustable screw rod of interior hexagonal.
Particularly, the export-oriented bulb that described two multi-directional ball are wherein connected with described tooth bar 2 is liner ball 6, and the export-oriented bulb being connected with described spindle arm 4 is 90 degree bulbs 7.Shown in liner ball 6 drive the directions 360 degree rotations of 90 degree bulbs 7 upper and lower 70 degree in front and back, realized the object that three-wheel vehicle wide-angle turns to.
Further, between described housing 1 and tooth bar 2, rack bush 5 is installed, the setting of rack bush 5, keeps tooth bar 2 to move point-blank, and tooth bar 2 operates steadily.
Further, described rack bush 5 is polyurethane laminar texture.Polyurethane wear resistant performance is good, mechanical strength is large, adhesive property is good, good springiness, has good nerve, and low temperature flexibility is good, good weatherability, long service life, good, the resistance to biological aging of fuel resistance, moderate cost.
This practicality is in the process of using, gear 3 rotates tooth bar 2 side-to-side movements that drive with its interlock, tooth bar 2 drives the direction of upper and lower 70 degree in liner ball 6 front and back to rotate, thereby drives 90 degree bulbs 7 in the direction 360 degree rotations of 70 degree, and 90 degree bulbs 7 drive spindle arm 4 to turn to; Spindle arm 4 is connected with three-wheel vehicle steering column, thereby drives three-wheel vehicle to turn to.In addition, gear 3 adopts mounting hole to be connected with shell 1, and described mounting hole is three, and gear 3 becomes 90 degree settings with the mounting hole on shell 1.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
