Abstract
The utility model discloses a guider for automobile shock absorber, it includes the guider body, is equipped with integrated into one piece's oil blanket terminal surface, major diameter lateral wall, lateral wall recess, oil groove and piston mounting hole on the guider body, and the oil groove runs through the straight wall section that major diameter lateral wall forms the oilhole, and the oilhole bottom is equipped with the step face, and the step face leans out, and major diameter lateral wall height is greater than piston mounting hole lateral wall height. The utility model discloses establish the step face in the oilhole for cooperation area of contact between director and the outside steel cylinder part increases, and the high increase of major diameter lateral wall, thereby has increased director bulk strength.
Description
Technical Field
The utility model relates to a technical field of automobile shock absorber, specifically a director for automobile shock absorber ware.
Background
The automobile shock absorber is one of important components of an automobile suspension system as a damping element in an automobile part, plays a decisive role in smoothness, comfort, safety, steering operability and trafficability of vehicle running, and the guider is one of important parts in the automobile shock absorber. The guider plays a good role in guiding the movement of a piston rod in the shock absorber, the working cylinder is communicated with the oil storage cylinder through the oil hole in the guider, the inclined oil hole at the oil seal end of the existing guider is directly communicated to the step end face through the vertical peripheral wall, oil directly drips from the outlet end of the inclined oil hole, the outlet end of the inclined oil hole is usually on the side wall with a large diameter, and the guider is integrally clamped between the outer steel cylinder and the inner steel cylinder, so that the contact surface is few when the guider is installed, and the use strength of the guider is reduced.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: the guider for the automobile shock absorber is provided, the step surface is arranged in the oil hole, so that the matching contact area between the guider and an external steel cylinder part is increased, the height of the large-diameter side wall is increased, and the integral strength of the guider is increased.
The utility model adopts the technical proposal that: the guider comprises a guider body, wherein the guider body is provided with an integrally formed oil seal end face, a large-diameter side wall, a side wall groove, an oil groove and a piston mounting hole, the oil groove penetrates through a straight wall section of the large-diameter side wall to form an oil hole, the bottom of the oil hole is provided with a step face, the step face inclines outwards, and the height of the large-diameter side wall is greater than that of the side wall of the piston mounting hole.
Preferably, the diameter of the bottom surface of the counter bore where the end face of the oil seal is located is larger than that of the end face, and the bottom of the counter bore is rounded, so that the processing is convenient.
Preferably, the large-diameter side wall and the outer wall of the piston mounting hole are directly transited through the inclined side wall, and the transition is different from the transition of the small-diameter side wall in the conventional technology, so that the overall strength of the guider is increased.
After the structure more than adopting, compared with the prior art, the utility model has the following advantage: the oilhole bottom is equipped with the step face, and the step face leans out, has increased the whole area of contact when blocking between outer steel cylinder and interior steel cylinder of director, and in addition, major diameter lateral wall height is greater than the path lateral wall height for the major diameter lateral wall height occupies the director overall height, thereby has all strengthened the bulk strength of director.
Drawings
Fig. 1 is a structural sectional view of the present invention.
The guide device comprises a guide device body 1, an oil seal end face 2, a large-diameter side wall 3, a side wall groove 4, an oil groove 5, an oil groove 6, a piston mounting hole 7, an oil hole 8, a step face 9 and a counter bore.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
The utility model provides a guider for automobile shock absorber, as shown in fig. 1, it includes director body 1, is equipped with integrated into one piece's oil blanket terminal surface 2, big footpath lateral wall 3, lateral wall recess 4, oil groove 5 and piston mounting hole 6 on the director body 1, and oil groove 5 runs through the straight wall section formation oilhole 7 of big footpath lateral wall 3, and 7 bottoms of oilhole are equipped with step face 8, and step face 8 leans out, and big footpath lateral wall 3 highly is greater than 6 lateral wall heights in piston mounting hole. The diameter of the bottom surface of the counter bore 9 where the oil seal end surface 2 is located is larger than that of the end surface, so that the counter bore 9 is in a shape with a large bottom and a narrow top, and the bottom of the counter bore is rounded. The major diameter lateral wall 3 directly passes through oblique lateral wall transition with 6 outer walls of piston mounting hole, need not conventional path lateral wall, not only strengthens director bulk strength, makes processing more convenient moreover.
While the above is directed to the preferred embodiment of the present invention, it is not intended that it be limited, except as by the appended claims. The present invention is not limited to the above embodiments, and the specific structure thereof allows for changes, all the changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
Claims (3)
1. The utility model provides a director for automobile shock absorber ware, it includes the director body, is equipped with integrated into one piece's oil blanket terminal surface, major diameter lateral wall, lateral wall recess, oil groove and piston mounting hole on the director body, and the oil groove runs through the straight wall section formation oilhole of major diameter lateral wall, its characterized in that: the bottom of the oil hole is provided with a step surface which inclines outwards, and the height of the large-diameter side wall is greater than that of the side wall of the piston mounting hole.
