Embodiment Construction

[0007] The present invention analyzes the prior art and finds that the reason why the oil seal stopper comes out of the oil cylinder 1 is that the used circlip 2 is an open circlip made of circular spring steel wire, and the circlip is interference fit on the inner wall of the hydraulic cylinder In the annular groove on the upper part, the oil seal stopper 4 sleeved on the rack 3 is blocked by the part exposed outside the inner wall of the hydraulic cylinder. For some reason, the axial oil pressure in the hydraulic cylinder increases, and the circlip is released from The arc groove of the oil cylinder wall slips off, causing the oil seal 5 to fail. Aiming at the reason why the above-mentioned oil seal stopper slipped from the hydraulic cylinder, the following technical solutions were adopted, one is to make the left arc surface of the circular body of the circlip 2 into a plane by grinding, and the other is to grind the The arc-shaped surface on the left side of the arc-shaped...

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: [0001] The invention relates to an automobile steering technology, in particular to a fixing structure of a steering gear oil seal block and a hydraulic cylinder. Background technique: [0002] In the hydraulic rack and pinion steering gear, in order to prevent the oil seal block from coming out of the hydraulic cylinder, a circlip structure is adopted, and the circlip is placed in the arc groove on the wall of the hydraulic cylinder. This anti-oil seal block slipping structure, during use There is a phenomenon that the block slips and the steering gear cannot work. Invention content: [0003] The object of the present invention is to provide a fixing structure of a steering gear oil seal stopper and a hydraulic cylinder with good anti-off effect. [0004] The technical solution of the present invention is a fixed structure of a steering gear oil seal block and a hydraulic cylinder, including a hydraulic cylinder, a circlip, an oil seal and an oil seal bl...
