Power off device for car speed signal control rectifier

Abstract

The invention discloses an outrage device of a vehicle speed signal control rectifier. The outrage device of the vehicle speed signal control rectifier is composed of an outer shell, a relay, a control module, a first line, a second line, a third line, a fourth line, an indicator light, a keyboard and a signal line. The outrage device of the vehicle speed signal control rectifier is characterized in that the relay and the control module are arranged in the outer shell, and the first line and the second line penetrate out of the power supply end of the control module. An output end of the control module is connected with an electromagnetic coil of the relay, the third line penetrates out of the common end of the relay, and the fourth line penetrates out of the normally-closed end of the relay. The signal input end of the control module is connected with the keyboard, and a second output end of the control module is connected with the indicator light. The signal line is led out from the control module, and the signal line is connected with a vehicle speed sensor of a vehicle. The outrage device of the vehicle speed signal control rectifier has the function of setting charging conduction angles of a starting speed and a cut-off speed so as to reduce the temperature of the rectifier and reduce waste of fuel of an engine and enhancing power of the engine.

Description

technical field [0001] The invention relates to a control technology capable of turning on and off a rectifier according to the running speed of a motorcycle, specifically a power-off device for controlling a rectifier by a vehicle speed signal. Background technique [0002] Motorcycles generally adopt the short-circuit voltage stabilization method. This structure is simple, but the load of the magneto is large, and all the excessive voltage of the generator leaks from the ground wire, causing the temperature of the thyristor to be too high. Secondly, in order to overcome the load of the magneto The magnetic cutting force will inevitably cause unnecessary waste of fuel; and as a switch-controlled rectifier, although it has the function of disconnecting the connection between the magneto and the rectifier at full power, the instantaneous high voltage generated when it is disconnected and combined is easy to cause SCR burned out.

Problems solved by technology

[0002] Motorcycles generally adopt the short-circuit voltage stabilization method. This structure is simple, but the load of the magneto is large, and all the excessive voltage of the generator leaks from the ground wire, causing the temperature of the thyristor to be too high. Secondly, in order to overcome the load of the magneto The magnetic cutting force will inevitably cause unnecessary waste of fuel; and as a switch-controlled rectifier, although it has the function of disconnecting the connection between the magneto and the rectifier at full power, the instantaneous high voltage generated when it is disconnected and combined is easy to cause SCR burned out

[0003] At the same time, in the uninterrupted charging mode, although the battery is always fully charged, there is no discharge process, and the life of the battery is greatly shortened

[0004] Furthermore, the displacement of the motorcycle is small, and the load of the magneto causes weak starting, and at high speed, the load of the magneto and air resistance cause disadvantages such as inability to go up at high speed.
