Abstract
The utility model relates to a heavy forklift steering bridge with improved hub bearing location. The heavy forklift steering bridge is improved as follows: an external check ring is arranged between an inner step of a stepped shaft of a steering knuckle and a big tapered roller bearing position, an O-shaped sealing ring is arranged between the inner step and the external check ring, and a dust ring is arranged between the periphery of the external check ring and a hub; an inner check ring is arranged between an external step and a retaining nut; and the inner side face of a main pin cover, corresponding to the hub end face, is provided with a sealing ring groove, and the sealing ring with O-shaped end face is arranged in the sealing ring groove. The heavy forklift steering bridge comprises the inner check ring and the external check ring, and is convenient to process; the size can be designed as needed; if a locating surface is damaged, the damaged locating surface can be changed conveniently with low cost; and simultaneously, the difficulties in processing of the steering knuckle are reduced greatly.
Description
Technical field
The utility model belongs to the forklift steering bridge technical field, is specifically related to the forklift steering bridge of resetting.
Background technology
The forklift steering bridge hub bearing is the tapered roller bearing that a pair of dos-is installed, and is the most important loading bearing of steeraxle.Character of bearing own and all requirements of bearing operating mode, its locating surface will have good roughness and planeness requirement, and two its working environment lubricating condition will be got well.Existing hub bearing locate mode does, inner ring located with jam nut with steering swivel step surface location inner ring outside the conicle roller in the sub-bearing of the big conical tube outside, and wheel hub step surface location bearing outer ring is all used in the inboard; Sealing means is that big tapered roller bearing end seals with the dust ring seal ring, and conicle Roller Shaft socket end is employed in the mode that increases packing seal between wheel hub cover and the wheel hub and seals or directly do not seal.This kind project organization has following shortcoming: 1, steering swivel need provide a step surface to be used for big tapered roller bearing location; Make the slewing journal structure relative complex; And because this step surface must guarantee good roughness and planeness; Need fine limit work, heavy fork-truck steering joint size is very big, and the fine limit work difficulty is bigger.If this step surface is worn or destroys, be difficult to repair, need directly to change steering swivel.What 2, the forklift steering bridge jam nut adopted is national standard part circular nut, adopts it to conicle coro bearng location, and size is dumb, and its end face roughness and planeness be difficult to reach requirement, and the normal use of hub bearing is had bad influence.3, conicle Roller Shaft socket end utilizes the sealing that form of packers is carried out, and through after working long hours, packing seal might damage; Cause to be used for the lubricated grease of hub bearing and to leak, bearing is worked under few lubricated even unlubricated operating mode, operating mode is abominable; Cause the improper service failure of bearing, this packing seal generally adds glue for guaranteeing sealing effectiveness during assembling simultaneously; Open again after the assembling and will damage, can't second use.
Summary of the invention
For the difficulty of processing that reduces steering swivel, guarantee that the location is reliable, guarantee the lubricating condition of hub bearing simultaneously, and can carry out repeated disassembled and assembled and be not damaged that the utility model provides a kind of heavy forklift steering bridge that improves the hub bearing location that has.
Concrete improvement technical scheme is following:
Having the heavy forklift steering bridge that improves the hub bearing location comprises and turns to pontic; Turn to the two ends of pontic connecting steering swivel respectively; Be provided with wheel hub through big tapered roller bearing, conicle coro bearng and jam nut on the step axle of steering swivel, the step axle of steering swivel has two stage steps, i.e. inner side step and outside step; Big tapered roller bearing is positioned at the inner side step place, and the conicle coro bearng is positioned at step place, the outside; The outer end of wheel hub is provided with kingpin cap, is provided with outer back-up ring between said inner side step and the big tapered roller bearing position, is provided with the O RunddichtringO between inner side step and the outer back-up ring, is provided with dust ring between outer back-up ring periphery and the wheel hub; Be provided with inner shield ring between outside step and the jam nut.
Be provided with closure gasket groove with the cooresponding kingpin cap medial surface of hub end face, be provided with end face O RunddichtringO in the said closure gasket groove.
The utility model is compared with prior art products and is had the advantage of following aspect:
1. slewing journal structure is simple relatively, has significantly reduced the difficulty of processing of steering swivel;
2. simple, the processing easily of inside and outside back-up ring profile, size can design as required; Damage problem if locating surface takes place, it is convenient to change, and cost is low;
3. adopt the sealing of O type circle, sealing is reliable, effectively guarantee the work life and the reliability of hub bearing, and O type circle can be recycled.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model structure is done explanation further through embodiment.
Referring to Fig. 1; Have the heavy forklift steering bridge that improves the hub bearing location and comprise and turn to pontic 1, turn to the two ends of pontic 1 connecting steering swivel 6 respectively, through big tapered roller bearing 3, conicle coro bearng 4 and jam nut 8 wheel hub 9 is installed on the step axle of steering swivel 6; The step axle of steering swivel 6 has two stage steps; Be inner side step and outside step, big tapered roller bearing 3 is positioned at the inner side step place, and conicle coro bearng 4 is positioned at step place, the outside; The outer end of wheel hub 9 is equipped with kingpin cap 7 through bolt.Between inner side step and the big tapered roller bearing 3 outer back-up ring 2 is housed, between inner side step and the outer back-up ring 2 O RunddichtringO 11 is installed, between outer back-up ring 2 peripheries and the wheel hub 9 dust ring 10 is installed; Between outside step and the jam nut 8 inner shield ring 5 is installed.Outer back-up ring 2 is the annulus of band chamfering, and inner shield ring 5 be common annulus, and outer back-up ring 2 is easily manufactured with inner shield ring 5, this locate mode to hub bearing, to steering swivel require lowly, the location is reliably.With offer closure gasket groove on cooresponding kingpin cap 7 medial surfaces of wheel hub 9 end faces, end face O RunddichtringO 12 is installed in the closure gasket groove.Installation through dust ring 10, O RunddichtringO 11 and 12 3 sealing members of end face O RunddichtringO; The working space of hub bearing is sealed fully; The bearing working worsening condition of effectively having avoided lubricating grease to leak causing, and impurity such as dust gets into the bearing working track, causes the damage of the improper property of bearing; Improve the functional reliability of bearing, guaranteed the service life of bearing.
