Abstract
The utility model provides a buffer cylinder for rail vehicle steering cylinder, including the steering cylinder assembly, be equipped with buffer cylinder assembly on the steering cylinder assembly, be equipped with two pressure hydraulic fluid ports on the cylinder body of steering cylinder assembly and buffer cylinder assembly's the cylinder body respectively, two pressure hydraulic fluid ports of steering cylinder assembly and buffer cylinder assembly dock mutually. Use a buffer cylinder for rail vehicle steering cylinder, connect rail vehicle automobile body and bogie, during the turn, restrict relative motion between the two, buffer cylinder reduces the system pressure peak value, coordinates each section vehicle and realizes hydraulic steering, jolts when reducing the vehicle turn.
Description
Technical Field
The utility model relates to a steering cylinder for vehicle, especially a buffer cylinder for rail vehicle steering cylinder.
Background
According to the existing railway vehicle, when the vehicle turns, all the vehicles sequentially pass through a curve, all the vehicles are not coordinately controlled by a hydraulic steering oil cylinder, and the vehicles bump when passing through the curve.
The steering oil cylinder is mainly applied to a railway vehicle and is connected with a railway vehicle body and a bogie, and when the railway vehicle turns, the relative motion between the railway vehicle body and the bogie is limited, but when the relative motion is limited, the bumping of the vehicle when the vehicle turns is easy to occur due to the high pressure peak value of the system.
Disclosure of Invention
The utility model aims at providing a buffer cylinder for rail vehicle steering cylinder increases buffer cylinder on the steering cylinder assembly, reduces the system pressure peak value, coordinates each section vehicle and realizes hydraulic steering, jolts when reducing the vehicle and turning.
In order to solve the technical problem, the technical scheme of the utility model as follows: the utility model provides a cushion cylinder for rail vehicle steering cylinder, includes the steering cylinder assembly, its characterized in that: the steering oil cylinder assembly is provided with a buffer oil cylinder assembly, the cylinder body of the steering oil cylinder assembly and the cylinder body of the buffer oil cylinder assembly are respectively provided with two pressure oil ports, and the two pressure oil ports of the steering oil cylinder assembly and the two pressure oil ports of the buffer oil cylinder assembly are in butt joint.
The improvement of the technical scheme is as follows: the cylinder body of the steering oil cylinder assembly is connected with a cylinder cover provided with a groove and provided with a sealing element through a bolt to form a pressure cavity.
The technical scheme is further improved as follows: the steering oil cylinder assembly is characterized in that a cylinder body and a cylinder cover of the steering oil cylinder assembly are processed by alloy steel, and paint layers are arranged on the surfaces of the cylinder body and the cylinder cover.
The technical scheme is further improved: the steering oil cylinder assembly and the buffer oil cylinder assembly are both double-rod hydraulic cylinders.
Has the advantages that:
use a buffer cylinder for rail vehicle steering cylinder, connect rail vehicle automobile body and bogie, during the turn, restrict relative motion between the two, buffer cylinder reduces the system pressure peak value, coordinates each section vehicle and realizes hydraulic steering, jolts when reducing the vehicle turn.
Drawings
FIG. 1 is a schematic view of the hydraulic principle of the present invention;
wherein: 1. The hydraulic control system comprises a steering oil cylinder assembly, 2 a buffer oil cylinder assembly, a pressure oil port A and a pressure oil port B.
Detailed Description
As shown in fig. 1, the buffer cylinder for the rail vehicle steering cylinder assembly 1 comprises a cylinder body provided with an oil passage, wherein the cylinder body is connected with a cylinder cover provided with a groove and a sealing element through a bolt to form a pressure cavity; the cylinder body and the cylinder cover of the steering oil cylinder assembly 1 are processed by alloy steel, and the surface of the cylinder body and the cylinder cover is treated by paint; the cylinder cover is provided with two pressure oil ports which are respectively an A port and a B port; a piston rod and a double-rod hydraulic cylinder are arranged in the cylinder body, and the acting force is the same under the condition of the same pressure in the stroke and the return stroke. The port A and the port B of the steering oil cylinder assembly 1 are respectively connected with the port A and the port B of the buffer oil cylinder assembly 2; when the rail vehicle turns, all the vehicles sequentially pass through a curve, the pressure of the port A of the steering oil cylinder assembly 1 rises, the pressure of the port A of the buffer oil cylinder assembly 2 rises, the pressure of the port B of the steering oil cylinder assembly 1 rises, after the vehicle passes through the curve, the piston is pushed to the middle position by the spring force of the buffer oil cylinder assembly 2, the pressures of the port A and the port B of the buffer oil cylinder assembly 2 change, so that the steering oil cylinder piston moves to the middle position under the hydraulic action, and the steering oil cylinder returns to the original position.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
