Abstract

The utility model discloses a guider for a vehicle shock absorber. The guider comprises an outer cylinder assembly surface (1), an oil seal end die cavity (2) and a conical surface (3) which are arranged on the guider body. The guider is characterized in that radial grooves (4) for communicating a working cylinder and an oil storage cylinder are formed at the connection between the conical surface (3) and the outer cylinder assembly surface (1) of the guider body, and the radial grooves (4) are distributed along the axial direction of the guider body and communicated with the oil seal end die cavity (2). The guider has the advantages that oil seal blowout in the vehicle shock absorber can be avoided, and the product processing cost can be reduced.

Description

The vehicle shock absorber guider

Technical field

The utility model relates to a kind of auto parts, specifically is a kind of vehicle shock absorber guider.

Background technique

Vehicle shock absorber is one kind damping member, it is one of important composition element of automobile suspension system, smoothness, travelling comfort, Security, steering operation and passing ability to vehicle driving play conclusive effect, and wherein guider is one of strength member in the vehicle shock absorber.Guider has played good leading role to the motion of piston rod in the vibration damper, and has born the huge lateral force that produces therefrom, and the oilhole by guider is communicated with clutch release slave cylinder and oil storage cylinder simultaneously.

As shown in Figure 1, existing guider body is a powder metallurgy forming, promptly form by the upper and lower mould once-through, this oilhole 4.1 is located at the conical surface 3.1 places of guider body, its oilhole 4.1 is general to be adopted the structure of manholes and with the axis of guider body certain angle is arranged, but because the restriction of powder metallurgical technique, the side direction oilhole 4.1 of guider body can't the compression moulding and the demoulding, but needs to adopt follow-up machining.Like this, on the one hand, because the personal factor that machining exists is too many, the phenomenon of processing occurs leaking through regular meeting, all hole even examine the also very difficult product that guarantees entirely, major hidden danger has been buried in this explosion for oil sealing in the vibration damper using process; On the other hand, machining also makes the manufacturing procedure of product increase, thereby has increased the processing cost of product.

The model utility content

Technical problem to be solved in the utility model is that a kind of vehicle shock absorber guider that can avoid oil sealing explosion phenomenon in the vehicle shock absorber, reduce the product processing cost is provided.

For solving the problems of the technologies described above, a kind of vehicle shock absorber guider that the utility model provides comprises the outer cylinder mating face, oil sealing end die cavity and the conical surface that are located on the guider body; The joint of the conical surface of described guider body and outer cylinder mating face is provided with the radial groove that is used to be communicated with clutch release slave cylinder and oil storage cylinder, and described radial groove is communicated with along guider body axial distribution and with oil sealing end die cavity.

After adopting above structure, the utility model compared with prior art, have the following advantages: because the conical surface place of described guider body is provided with the radial groove that is used to be communicated with clutch release slave cylinder and oil storage cylinder, described radial groove is communicated with along the axial distribution of guider body and with oil sealing end die cavity, make the radial groove of guider when die cast, can rely on the direct once-through of mould and the demoulding, need not follow-up machining, the phenomenon that oilhole leaks processing can not appear, can avoid oil sealing explosion phenomenon in the vehicle shock absorber, also reduce the machining cost of product.

As improvement, described radial groove is a rectangle groove, is easy to processing.

Description of drawings

Fig. 1 is to be the structural representation of the vehicle shock absorber of prior art with guider;

Fig. 2 is the structural representation of vehicle shock absorber of the present utility model with guider;

Fig. 3 is the A-A generalized section of Fig. 2.

As shown in the figure:

The utility model: 1, outer cylinder mating face, 2, oil sealing end die cavity, 3, the conical surface, 4, radial groove.

Prior art: 1.1, outer cylinder mating face; 2.1, oil sealing end die cavity 3.1, the conical surface; 4.1, oilhole.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

As shown in Figure 1, the vehicle shock absorber guider of prior art, comprise the outer cylinder mating face 1.1, oil sealing end die cavity 2.1 and the conical surface 3.1 that are located on the guider body, the conical surface 3.1 places of described guider body are provided with the oilhole 4.1 that is used to be communicated with clutch release slave cylinder and oil storage cylinder, and the axis of described oilhole 4.1 has certain angle with the axis of guider body and is communicated with oil sealing end die cavity 2.1.The described oilhole 4.1 general manholes that adopt.

As Fig. 2, shown in Figure 3, vehicle shock absorber guider of the present utility model comprises the outer cylinder mating face 1, oil sealing end die cavity 2 and the conical surface 3 that are located on the guider body; The conical surface 3 of described guider body and the joint of outer cylinder mating face 1 are provided with the radial groove 4 that is used to be communicated with clutch release slave cylinder and oil storage cylinder, described radial groove 4 is communicated with along guider body axial distribution and with oil sealing end die cavity 2, it is the parallel axes of the axis and the guider body of radial groove 4, described radial groove 4 is a rectangle groove, and promptly be communicated with the hole at place with oil sealing end die cavity 2 be rectangular opening to radial groove 4.

Claims

1. a vehicle shock absorber guider comprises the outer cylinder mating face (1), oil sealing end die cavity (2) and the conical surface (3) that are located on the guider body; It is characterized in that: the joint of the conical surface of described guider body (3) and outer cylinder mating face (1) is provided with the radial groove (4) that is used to be communicated with clutch release slave cylinder and oil storage cylinder, and described radial groove (4) is communicated with along guider body axial distribution and with oil sealing end die cavity (2).

2. vehicle shock absorber guider according to claim 1 is characterized in that: described radial groove (4) is a rectangle groove.
