Device capable of rolling and sliding synchronously

Abstract

The invention discloses a device capable of rolling and sliding synchronously and belongs to the technical field of mechanical design. The device comprises an adjusting body, a rotary shaft, a rotary body, a stretching body, off-center bodies, balls, a pull rod and springs; the rotary shaft and the rotary body are fixedly connected, the stretching body and the off-center bodies are evenly distributed in the rotary body, and the balls are inlaid on the stretching body; one side walls of the off-center bodies make contact with the stretching body through the balls, and the other side walls of the off-center bodies are connected with the inner wall surface of the rotary body through the first springs; the top of the stretching body is connected with the inner wall surface of the rotary body through the second spring. According to the device capable of rolling and sliding synchronously, when the rotating speed of an engine is high, an adjusting board moves upwards, the out-gassing amount of a turbine is large, and pumping loss is small; when the rotating speed of the engine is low, the adjusting board moves downwards, the out-gassing amount of the turbine is small, and exhaust pulse energy can be sufficiently used. The device capable of rolling and sliding synchronously is reasonable in design, simple in structure, and suitable for optimal design of a turbine out-gassing system.

Description

technical field [0001] The invention relates to a rolling-sliding synchronous device in the technical field of mechanical design, in particular to a rolling-sliding synchronous device applicable to a turbine deflation system. Background technique [0002] Turbocharging is a technology that uses the exhaust gas generated by the operation of an internal combustion engine to drive an air compressor. The main function of turbocharging is to increase the air intake of the engine, thereby increasing the power and torque of the engine and making the car more powerful. After an engine is equipped with a turbocharger, its maximum power can be increased by 40% or even higher compared with that without a supercharger. This also means that the same engine can output more power after being supercharged. Take our most common 1.8T turbocharged engine as an example. After supercharging, the power can reach the level of a 2.4L engine, but the fuel consumption is not much higher than that o...

Problems solved by technology

However, the existing turbocharging systems cannot take into account the high and low speed conditions of the engine well.

[0003] In the existing technology, in order to take into account the high and low speed conditions of the engine, the turbocharger often has a wastegate valve, but the wastegate valve is closer to the turbine, resulting in a higher temperature of the valve body, and must pass The engine intake pressure is adjusted, and it cannot be self-adjusted according to the engine speed
