Abstract
The utility model discloses a cylinder cover of a brake cylinder. The cylinder cover of the brake cylinder mainly comprises a cylindrical shell body, wherein the left end face of the shell body is not sealed, hollow cylinders are arranged on the outer circle face of the cylindrical shell body, and threaded holes are formed in the cores of the hollow cylinders. The cylinder cover of the brake cylinder is characterized in that a certain distance exists between the left end face of each hollow cylinder and the left end face of the cylindrical shell body, an oil inlet-and-outlet hole connector is arranged on the right end face of each hollow cylinder, and an oil inlet-and-outlet hole which penetrates to the inner wall of the cylindrical shell body is formed in the core of each oil inlet-and-outlet hole connector. Due to the fact that a gap with a certain size is reserved between the end portion of each hollow cylinder on the outer circle face of the non-sealed end portion of the cylinder cover of the brake cylinder and the corresponding side end face of the cylinder cover of the brake cylinder, the corresponding side end portion of the cylinder cover can be embedded into a cylinder body which is prefabricated and is matched, and the phenomenon of leakage at the position of a bolt installing hole is completely eradicated. Due to the fact that the oil inlet-and-outlet holes are connected to the outer circle face of the cylinder cover of the brake cylinder through the oil inlet-and-outlet hole connectors, the cylinder cover of the brake cylinder can be conveniently connected with an oil pipeline.
Description
Technical field
The utility model relates to a kind of master cylinder cylinder cap, especially a kind of master cylinder cylinder cap of good seal performance.
Background technique
In the rail vehicles system, utilize hydraulic jack as power unit, utilize the corresponding moving element of action drives of oil cylinder to move, the to-and-fro motion of the piston by being placed in hydraulic jack is for single unit system provides driving.Hydraulic jack is comprised of cylinder body and cylinder cap, at present general is to be placed in cylinder body one side end by cylinder cap, by the mounting plate bolt with the periphery of the hollow cylinder tapped hole on the periphery of cylinder cap end and cylinder ends, but do like this because hollow cylinder tapped hole end face is concordant with cylinder body respective side end face, thereby will there be the problem of leakage in the bolt connecting hole position, considers the cylinder cap of a kind of good seal performance of research for this reason.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of master cylinder cylinder cap, has the characteristics of good seal performance.
for solving the problems of the technologies described above, the technical solution of the utility model is: a kind of master cylinder cylinder cap, be mainly the cylindrical body housing of left side open-ended, on the external disc of described cylinder case along being provided with one or more hollow cylinder on the hollow cylinder axial direction, described hollow cylinder core has tapped hole, and described hollow cylinder and cylindrical body housing are structure as a whole, its innovative point is: between the left side of described hollow cylinder and cylindrical body housing left side, certain distance is arranged, the right side of described hollow cylinder is concordant with cylindrical body housing right side, and wherein be provided with turnover oilhole connecting head on the position, right side of a hollow cylinder, the central axis of described turnover oilhole connecting head is perpendicular to the central axis of this hollow cylinder, described turnover oilhole connecting head core has the turnover oilhole that penetrates into cylindrical body housing inwall.
Further, described cylindrical body housing is symmetrically arranged with two support lug structures on the right side, and on described two support lug structures, the corresponding position has the hole that lifts of perforation, describedly lifts the hole central axis and cylindrical body housing central axis is perpendicular.
The utility model has the advantage of: by with the hollow cylinder end of body on the periphery of master cylinder cylinder cap open-ended end, and leave certain gap between master cylinder cylinder cap respective side end face, thereby make cylinder cap respective side end be embedded in the cylinder body of prefabricated cooperation, thereby stopped the leakage problem that occurs from the bolt mounting holes position.To pass in and out oilhole and be connected to master cylinder cylinder cap periphery by turnover oilhole connecting head, thereby be convenient to be connected with the oil pipe pipeline.
On the end face of the non-attachment face of master cylinder cylinder cap, support lug structure is set, and opens the hole that lifts of perforation on support lug structure, thereby be convenient to lift.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the plan view of a kind of master cylinder cylinder cap of the utility model.
Fig. 2 is the left view of a kind of master cylinder cylinder cap of the utility model.
Fig. 3 is the plan view of a kind of master cylinder cylinder cap of the utility model.
Embodiment
Fig. 1 to a kind of master cylinder cylinder cap shown in Figure 3 comprise left side 3, cylindrical body housing left side 4, the hollow cylinder of cylindrical body housing 1, hollow cylinder 2, hollow cylinder right side 5, cylindrical body housing right side 6, turnover oilhole connecting head 7, turnover oilhole 8, support lug structure 9, lift hole 10.
Master cylinder cylinder cap of the present utility model is mainly the cylindrical body housing 1 of left side open-ended, on cylindrical body housing 1 periphery along being provided with one or more hollow cylinder 2 on the hollow cylinder axial direction, these hollow cylinder 2 cores have tapped hole, and hollow cylinder 2 is structure as a whole with cylindrical body housing 1.For strengthening the sealability of master cylinder cylinder cap and the parts that match, there is certain distance 4 of the left side 3 of hollow cylinder and cylindrical body housing left sides, the right side 5 of described hollow cylinder is concordant with cylindrical body housing right side 6, and wherein be provided with turnover oilhole connecting head 7 on 6 positions, right side of a hollow cylinder, the central axis of described turnover oilhole connecting head 7 is perpendicular to the central axis of this hollow cylinder 2, and described turnover oilhole connecting head 7 cores have the turnover oilhole 8 that penetrates into cylindrical body housing 1 inwall.
For ease of lifting, be symmetrically arranged with two support lug structures 9 on cylindrical body housing right side 6, what on this two support lug structure 9, the corresponding position had a perforation lifts hole 10, lifts hole 10 central axis and cylindrical body housing 1 central axis perpendicular.
During concrete the installation, make cylindrical body housing left side 4 exceed hollow cylinder left side 3 parts and be embedded in the cylinder ends of prefabricated cooperation, thereby stopped the leakage problem of bolt link position from the hollow cylinder.
