In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1, the present utility model provides a charging device for a passenger car, comprising a charging bow 1 and a pantograph 2, wherein the charging bow 2 is contacted with the charging bow 1 to charge the passenger car 3.

An electric traction locomotive obtains electric energy from a contact net and is arranged on the locomotive or a motor train roof. The pantograph 2 can be divided into a single-arm pantograph and a double-arm pantograph, and comprises a sliding plate, an upper frame, a lower arm rod (a lower frame for the double-arm pantograph), a bottom frame, a pantograph lifting spring, a transmission cylinder, a supporting insulator and the like. Diamond pantographs 2, also called diamond pantographs 2, have been very popular in the past, and later have been gradually eliminated due to high maintenance costs and the tendency to break contact lines in the event of a failure, and single-arm pantographs have been used in recent years. The smoothness of the load current passing through the contact line and the contact surface of the contact plate of the pantograph 2 is related to the contact pressure, the transition resistance and the contact area between the contact plate and the contact line, and depends on the interaction between the pantograph 2 and the contact line. Compressed air uniformly enters the transmission cylinder through the electric air valve, the piston of the cylinder compresses the bow-descending spring in the cylinder, at the moment, the bow-ascending spring enables the lower arm rod to rotate, the upper frame and the sliding plate are lifted, the pantograph 2 ascends at a uniform speed, and when approaching the contact line, the pantograph slowly stagnates and then contacts the contact line rapidly. Compressed air in the transmission cylinder is rapidly discharged to the atmosphere through the buffer valve of the pantograph 2, and under the action of the pantograph descending spring, the acting force of the pantograph ascending spring is overcome, so that the pantograph 2 rapidly descends and is separated from the contact net.

The smoothness of the load current passing through the contact line and the contact surface of the contact plate of the pantograph 2 is related to the contact pressure, the transition resistance and the contact area between the contact plate and the contact line, and depends on the interaction between the pantograph 2 and the contact line.

In order to ensure smooth flow of traction current, a certain contact pressure is required between the pantograph 2 and the contact line. The actual contact pressure of the bow net is composed of four parts: the pantograph 2-liter-bow system applies a vertical force upward to the slide plate to be a static contact pressure (generally 70N or 90N); because of the elasticity difference of the contact suspension, the contact line can rise to different degrees under the lifting action of the pantograph 2, so that the pantograph 2 can vibrate up and down in operation, and the pantograph 2 can generate an up-down alternating dynamic contact pressure related to the quality of the contact line; the pantograph 2 generates a rapidly increasing aerodynamic force with increasing speed under the action of air flow in operation; damping forces generated by each joint of the pantograph 2 in the process of lifting and lowering the pantograph.

The contact pressure of the bow net can intuitively reflect the contact condition between the sliding plate of the pantograph 2 and the contact line, and the contact pressure must conform to the normal distribution rule and fluctuate within a certain range. If too small, the offline rate may be increased; if too large, greater mechanical wear between the sled and the contact wire may occur. In order to ensure reliable current-receiving quality of the pantograph 2, the calculated quality of the pantograph 2 should be reduced as much as possible, and the elastic uniformity of contact suspension is increased. The mass and electromechanical properties of the skateboard have a great influence on the quality of the current.
