Abstract
The utility model discloses a kind of fork axle steering structure, it comprises seal ring, axle housing, needle bearing, O shape circle, thrust ball bearing, steering swivel, knuckle pivot pin and bearing carrier ring; Described seal ring, needle bearing and O shape circle are arranged in bearing carrier ring and form bearing carrier ring assembly, and this bearing carrier ring assembly is arranged on axle housing; Described steering swivel and thrust ball bearing are arranged on axle housing by knuckle pivot pin.Adopting this fork axle steering structure, having when keeping in repair when forklift steering bridge needle bearing premature failure without the need to changing axle housing, maintenance is efficiently convenient, service expenditure is low feature.
Description
Technical field
The utility model relates to a kind of steering hardware, is the steering hardware of forklift steering bridge by it.
Background technology
At present, the little tonnage fork car bridge steering structure of domestic main flow mainly comprises axle housing, oil cylinder, connecting rod, steering swivel, knuckle pivot pin, needle bearing and thrust ball bearing, wherein steering swivel is arranged on axle housing by knuckle pivot pin, thrust ball bearing, two needle bearings, realizes fork-truck steering by oil cylinder pushing connecting rod and steering swivel.Problems existing is: the needle bearing of band drawn cup easily damages in bad working environments use procedure, when this bearing premature breakdown rear steering joint pin easily causes the wearing and tearing of axle housing bearing hole position; So when needle bearing breaks down, maintenance not only must change the associated damage parts such as bearing, also must change axle housing, cause inconvenient maintenance, cost high.
Summary of the invention
The purpose of this utility model is to provide a kind of fork axle steering structure, and without the need to changing axle housing when making to keep in repair at forklift steering bridge needle bearing premature failure, it is efficiently convenient to keep in repair, thus reduces forklift steering bridge after-sales service expense.
For realizing above object, the utility model one fork axle steering structure comprises seal ring, axle housing, needle bearing, O shape circle, thrust ball bearing, steering swivel, knuckle pivot pin and bearing carrier ring; Described seal ring, needle bearing and O shape circle are arranged in bearing carrier ring and form bearing carrier ring assembly, and this bearing carrier ring assembly is arranged on axle housing; Described steering swivel and thrust ball bearing are arranged on axle housing by knuckle pivot pin.
Above-mentioned one fork axle steering structure has following characteristics:
1. the needle bearing, by strengthening axle housing installs aperture, increase a bearing carrier ring, make when bearing break down need keep in repair time simple and fast, only need change the associated damage such as bearing carrier ring and bearing part, and axle housing still can continue to use, solve the problem that axle housing need be changed because of bearing damage.
2., assembling time, first needle bearing is installed in bearing carrier ring, then handle component be installed to axle housing complete assembly install, can directly change bearing carrier ring assembly during maintenance, greatly improve maintenance efficiency.
Adopt the utility model one fork axle steering structure, only bearing carrier ring, needle bearing, knuckle pivot pin and associated seal need be changed when needle bearing occurs that premature failure need keep in repair, and axle housing still can repeated usage without the need to change, there is easy to maintenance, that service expenditure is low feature.
Accompanying drawing explanation
Fig. 1 is the main cross-sectional schematic of the utility model one fork axle steering structure.
Reference numeral: seal ring 1, axle housing 2, needle bearing 3, O shape circle 4, thrust ball bearing 5, steering swivel 6, knuckle pivot pin 7, bearing carrier ring 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model one fork axle steering structure is described in further detail.
The one of the utility model shown in Fig. 1 fork axle steering structure comprises seal ring 1, axle housing 2, needle bearing 3, O shape circle 4, thrust ball bearing 5, steering swivel 6 and knuckle pivot pin 7, installs aperture, add a bearing carrier ring 8 by the needle bearing strengthening axle housing; First seal ring 1, needle bearing 3 and O shape circle 4 are assemblied in bearing carrier ring 8 during assembling, then this bearing carrier ring assembly is arranged on axle housing 2; Steering swivel 6, thrust ball bearing 5 are arranged on axle housing 2 by knuckle pivot pin 7.
Assembling rear steering joint 6 can rotate around knuckle pivot pin 7, and during use, fork truck bridge oil cylinder promotes steering swivel 6 by pipe link and realizes fork truck bridge turning function.The utility model can realize breaking down when needle bearing 3, knuckle pivot pin 7 can not cause wearing and tearing to axle housing 2, bearing carrier ring 8, seal ring 1, needle bearing 3, O shape circle 4 and knuckle pivot pin 7 only need be changed during maintenance, and axle housing 2 still can continue to use, there is convenient for maintaining and the low feature of maintenance cost.
