Abstract

The utility model belongs to an automobile steering device, which is mainly composed of a steering sectionn, a conical bearing, a main pin of a steering section, a front axle, etc. Because the adjustable interstitial conical bearing is used for replacing a traditional nonadjustable lining (a sliding bearing), the main pin of a steering section can not be worn, and the problems of no balance of an automobile direction machine, etc. can be overcome. The service life can exceed 100, 000 kilometers, the repair is very simple and convenient, the winding cutting or the hole enamel technology in the manufacturing and assembling process can be omitted, the working period can be reduced, and the effectiveness can be improved. The utility model which is adopted can achieve the purposes of safety, adjustment, economy, portable steering, durability, etc.

Description

Adjustable king-pin structure for steering knuckle

Adjustable king bdt structure relates to auto steerer.

Existing various 130 serial light trucks, passenger vehicle and other automobile all adopt the bush type steering yoke bolt to be equipped with the conventional confguration of thrust baring.The steering yoke bolt of domestic automobile and the tolerance clearance between the lining generally adopt twists the machine-shaping of cutting or bore a hole, can not adjust, surpass normal safe handling scope so wear and tear easily between steering yoke bolt and the lining, direction machine faults such as " pendulum " takes place when causing running car, has a strong impact on the safety of driver behavior.Wearing and tearing surpass normal operating limit when steering yoke bolt and lining gap, when having a strong impact on driving safety under steam, must in time change stub and lining, and repaired, and this repairing must possess special tool, cutter, and have relatively high expectations technical, cumbersome.Traditional stub structure useful life is short, generally must change, repair at 1～20,000 kilometer stroke, causes expending in a large number of material, accessory and fund.In the real work, the repairing of king bdt and lining is guaranteed that so the quality after repairing also be cannot say for sure card, the used life after the running repair will be than former car shortening 20%-30% being difficult to aspect the technology and equipment by what.Even if Japanese Toyota 130 automobiles, it is occupying clear superiority aspect material and the working accuracy, just needs the replacing accessory to be repaired about 30,000 kilometers but also can only travel, and is expensive very big.

At the above problem that exists in the prior art, the utility model from safety, reliable, durable, turn to several aspects such as light, change traditional lining into the garden cone bearing, the corresponding change of stub shape can be adjusted the tolerance clearance between stub and the steering swivel, keeps in repair extremely simple and convenient, but and expanded service life, in Automobile manufacturing and fitting process, reduce and twist the technology of cutting or bore a hole, the reduction of erection time, increase the benefit.

Structure of the present utility model is in conjunction with the accompanying drawings: Fig. 1 is that spindle and front axle are by main nitre connection diagram.Among the figure, garden cone bearing ［ 2 ］ is installed on the bearing seat ［ 7 ］ of steering swivel ［ 1 ］, steering yoke bolt ［ 4 ］ passes the hole of front axle ［ 9 ］, two ends cooperate with garden cone bearing ［ 2 ］, knuckle pivot pin ［ 4 ］ is by horizontal screw ［ 14 ］ and front axle ［ 9 ］ rigid fit cut, between front axle ［ 9 ］ and steering swivel ［ 1 ］ lower bearing, thrust ball bearing ［ 11 ］ and backing plate ［ 6 ］ are housed also, between thrust ball bearing ［ 11 ］ and backing plate ［ 6 ］, bearing cap shim ［ 12 ］ is housed, between front axle ［ 9 ］ and steering swivel ［ 1 ］ upper bearing lubriplate ［ 5 ］ and woollen blanket ［ 10 ］ are installed, two end faces up and down at the bearing seat ［ 7 ］ of steering swivel ［ 1 ］ are equipped with nut cap ［ 3 ］ in order to regulate bearing space, have zerk ［ 13 ］ on the nut cap ［ 3 ］, fixing between nut cap ［ 3 ］ and the bearing seat ［ 7 ］ with attachment screw ［ 8 ］.King bdt structure as shown in Figure 1 is suitable for the various automobile of what.To the what load carrying ability at the automobile below 2 tons, as shown in Figure 2, show by test, can reduce thrust bearing part, backing plate ［ 6 ］ can change iron sheet oil sealing ［ 16 ］ into, the available retaining oil cap of nut cap ［ 3 ］［ 15 ］ of steering swivel ［ 1 ］ lower shaft bearing lower surface replaces, and between bearing ［ 2 ］ and front axle ［ 9 ］ bearing cap shim ［ 12 ］ is housed all.

Generally speaking, compared with the prior art the utility model mainly is to adopt adjustable garden cone bearing to replace nonadjustable lining (plain bearing), and making steering yoke bolt pass through bearing space can adjust, and steering yoke bolt can not wear and tear.Adopt the utility model can prolong its period of service, useful life can surpass 100,000 kilometers, and can overcome direction machine problem such as " send out pendulum ", repairs also extremely simple and conveniently, can reach safe, adjustable, durable, economical, turn to purposes such as light.Also can reduce and twist the technology of cutting or bore a hole in its manufacturing and the fitting process, the reduction of erection time, increase the benefit.
