Abstract
The invention discloses a fixing structure of an oil seal check block and a hydraulic cylinder of a steering gear. The fixing structure comprises the hydraulic cylinder, a snap spring, an oil seal and the oil seal check block, and one side of the rounded body of the snap spring is a plane and is matched with an annular groove, composed of a left plane and an arc surface, in the hole wall of the hydraulic cylinder. The fixing structure has the remarkable advantage of reliably preventing the oil seal check block from slipping.
Description
Technical field:
The present invention relates to a kind of Automotive Steering Technology, particularly the fixed sturcture of a kind of redirector oil seal block and hydraulic actuating cylinder.
Background technology:
In the deflector of mekydro tooth bar in order to prevent that oil sealing block from deviating from from hydraulic actuating cylinder, adopt clip spring structure, jump ring is placed in deep-slotted chip breaker in cylinder wall, and the phenomenon that causes deflector to work in use appears block slippage and in this preventing oil seal block slippage structure.
Summary of the invention:
The object of the invention is to provide a kind of a kind of redirector oil seal block of good anti-drop effect and the fixed sturcture of hydraulic actuating cylinder.
Technical scheme of the present invention is, the fixed sturcture of a kind of redirector oil seal block and hydraulic actuating cylinder, comprise hydraulic actuating cylinder, jump ring, oil sealing and oil sealing block, it is characterized in that: a side of the round of described jump ring is that the circular groove that the plane by left side on plane and hydraulic actuating cylinder hole wall and arcwall face form matches.
The present invention has preventing oil seal block slippage failure-free remarkable advantage compared with the prior art.
Accompanying drawing explanation:
Fig. 1 is existing structure schematic diagram of the present invention; Fig. 2 is structural representation of the present invention.
The specific embodiment:
The present invention analyzes prior art, the reason that causes oil sealing block to be deviate from from oil cylinder 1 is, the opening jump ring that jump ring 2 used is made for coil component spring steel wire, jump ring is interference fitted in the circular groove on hydraulic actuating cylinder madial wall, dependence is exposed part outside hydraulic actuating cylinder madial wall and is stopped that the oil sealing block 4 being set on tooth bar 3 deviates from, and for a certain reason, the axial oil pressure in hydraulic actuating cylinder increases, jump ring, just from the deep-slotted chip breaker slippage of cylinder wall, causes oil sealing 5 to lose efficacy.Reason for the slippage from hydraulic actuating cylinder of above-mentioned oil sealing block, adopt following technical proposals, the one, the left side arcwall face of the round of jump ring 2 is made to plane by grinding, the 2nd, the left side arcwall face of the deep-slotted chip breaker in hydraulic actuating cylinder 1 hole wall is become to plane, opening jump ring is interference fitted in the groove on hydraulic actuating cylinder hole wall, make the left side plane of jump ring and the left side plane laminating of the circular groove on hydraulic actuating cylinder hole wall, when oil pressure increases, the jump ring that is provided with plane just can not take off from circular groove, thereby prevent the generation that jump ring slippage causes oil sealing 5 to lose efficacy, oil sealing 5, oil sealing block 4 and tooth bar 3 do not change.
Claims (1)
1. the fixed sturcture of a redirector oil seal block and hydraulic actuating cylinder, comprise hydraulic actuating cylinder, jump ring, oil sealing and oil sealing block, it is characterized in that: a side of the round of described jump ring is that the circular groove that the plane by left side on plane and hydraulic actuating cylinder hole wall and arcwall face form matches.
