Problems solved by technology

However, affected by the technical structure of pipelines and the durability of parts, oil pipes may burst during work, resulting in a sudden drop in the pressure of the hydraulic system, causing a greater impact on the vehicle and parts, resulting in damage to parts, or even traffic accident
For example, when the car is turning, the rupture of the oil pipe will cause the failure of the hydraulic system to assist the steering system, making the car out of control

Abstract

The invention provides a protective device of a hydraulic oil cylinder. The protective device of the hydraulic oil cylinder comprises a base, an inner circle and an elastic component, wherein the inner circle is arranged in an inner ring of the base, the inner circle is provided with an oil through hole, one end of the elastic component is arranged on the inner ring of the base, the other end of the elastic component is raised towards the direction away from the inner circle, and a part of the oil through hole is shielded when the elastic component deforms and is attached to the inner circle. Damage to related equipment and parts caused by flow and pressure jump of an oil pipe is avoided.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a hydraulic cylinder protection device and a hydraulic cylinder with the device. Background technique [0002] The hydraulic system is a device that transmits pressure through hydraulic oil, which converts the pressure energy of hydraulic oil into mechanical energy through hydraulic cylinders and hydraulic motors, so as to obtain the required linear reciprocating motion or rotary motion. Due to the large transmission force of the hydraulic system, which is easy to transmit and configure, it is widely used in industrial and civil industries, especially in the automotive field. [0003] At present, during the use of the hydraulic system of the automobile, the hydraulic cylinder is connected with other components through the oil pipe for power transmission. However, affected by the technical structure of pipelines and the durability of parts, oil pipes may burst during ...
