Novel automobile gear device solenoid valve

Abstract

The invention discloses a novel automobile gear device solenoid valve. The novel automobile gear device solenoid valve comprises a valve body. An oil cavity is formed in one side of the interior of the valve body, and an inner barrel is installed on the other side of the interior of the valve body. An oil scraping cavity is formed between the inner barrel and the oil cavity, and an oil scraping device is installed inside the oil scraping cavity. An armature is arranged inside the inner barrel. A valve element is arranged inside the oil cavity, a push rod is fixedly arranged between the valve element and the armature and passes through the oil scraping device, and a heating wire is installed on the circumferential exterior of the end, close to the valve element, of the push rod. According to the novel automobile gear device solenoid valve, the oil scraping device is arranged and can scrape the remaining oil away, and the phenomenon that the oil enters the interior of the inner barrel and affects the work of the armature can be avoided; and the heating wire is arranged, the oil inside the oil cavity can be turned into oil dirt under the condition that the novel automobile gear devicesolenoid valve is not used for a long time or it is cold, the heating wire can be energized to conduct heating, and therefore the generated oil dirt can be molten and be turned into the oil again, and the situation that due to the solidification of the oil, the movement of the valve element is blocked is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a novel electromagnetic valve for a gearshift of an automobile. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator and is not limited to hydraulic and pneumatic. It is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Solenoid valves can cooperate with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, and speed regulating valves. [0003] The gearshift of the car needs to be equipped with a solenoid valve, and th...
