Abstract

The utility model discloses a wet-type modified dry type hydraulic suspension which comprises a top support, wherein a bottom film is arranged below the top support, a top sealing cover is fixedly connected to the top of the top support in an inlaid manner, and a dry hole is formed in the center of the upper surface of the top sealing cover in a penetrating manner. According to the utility model, the dry hole is arranged at the top of the top sealing cover, the air in the equipment is exhausted through the dry hole, and then hydraulic oil is injected into the equipment through the dry hole, so that the traditional immersed wet filling is changed into dry filling, the outer wall of the equipment is cleaner, and the inconvenience in cleaning caused by the contamination of the outer wall with oil is avoided.

Description

Wet-type changes dry-type hydraulic suspension

Technical Field

The utility model relates to the technical field of hydraulic suspension of engines, in particular to a wet-type modified dry type hydraulic suspension.

Background

The hydraulic suspension is an automobile part for shock absorption, and the inside of the suspension is filled with oil. The working process of the system is to replace a common shock absorber by using an oil cylinder, and the height of the vehicle body is increased or decreased in a mode of increasing or decreasing hydraulic oil, namely, the ground clearance is automatically adjusted according to the vehicle speed and road conditions, so that the smoothness and the operation stability of the vehicle are improved. Suspension is an automotive powertrain for reducing and controlling the transmission of engine vibrations and serving as a support.

In the prior art, most of the hydraulic suspensions are wet-filled, i.e. the suspension is immersed under the liquid surface for filling, so that the wet assembly is difficult to remove the residual liquid on the surface.

Disclosure of Invention

The utility model aims to solve the technical problems that most of hydraulic suspensions in the prior art are wet suspensions, and residual liquid on the surface is difficult to remove in wet assembly.

In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides a wet-type changes dry-type hydraulic suspension, includes the top support, top support below position is provided with the basement membrane, top support top position inlays fixedly connected with top sealed lid, top sealed lid upper surface central point puts and runs through and has seted up the dry-type hole.

Through above-mentioned technical scheme, through setting up dry-type hole, the air in top support and the die block is evacuated through dry-type hole, and the hydraulic oil is annotated through dry-type hole through filling equipment to wet-type filling into dry-type filling.

The utility model further provides that a decoupling membrane is arranged at the center of the inner bottom wall of the bottom membrane.

The utility model is further arranged that a fixed connecting cylinder is fixedly connected between the bottom film and the top bracket in a clamping way.

The utility model further provides that a runner plate is arranged above the decoupling membrane.

The beneficial effects of the utility model are as follows:

according to the utility model, the dry hole is arranged at the top of the top sealing cover, the air in the equipment is exhausted through the dry hole, and then hydraulic oil is injected into the equipment through the dry hole, so that the traditional immersed wet filling is changed into dry filling, the outer wall of the equipment is cleaner, and the inconvenience in cleaning caused by the contamination of the outer wall with oil is avoided.

Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Referring to fig. 1-6, a wet-type modified dry hydraulic suspension comprises a top bracket 1, a bottom film 5 is arranged below the top bracket 1, a fixed connecting cylinder 4 is fixedly connected between the bottom film 5 and the top bracket 1 in a clamping manner, and a decoupling membrane 7 is arranged at the center of the inner bottom wall of the bottom film 5.

The upper position of the decoupling membrane 7 is provided with a runner plate 6, the top position of the top bracket 1 is inlaid and fixedly connected with a top sealing cover 3, and the central position of the upper surface of the top sealing cover 3 is penetrated and provided with a dry hole 2.

When the utility model is used, after the assembly is completed, the gas in the utility model is pumped out through the dry hole 2, and hydraulic oil is poured into the equipment through the dry hole 2 after the pumping out is completed, so that the wet filling is not changed into the dry filling, and the outside of the equipment is prevented from being polluted by the hydraulic oil.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
