Braking device for preventing throttle failure

Abstract

The invention relates to a braking device for preventing throttle failure. The braking device overcomes the defect that an electronic throttle unavoidably has the risk of being out of control because of a complex structure of an electronic system in the prior art, so that the combustion and the air inlet of the engine cannot be controlled by the electronic throttle and a vehicle has safety risk. The braking device comprises a fixing supporting frame which is arranged at an entrance of an air inlet pipe of an air filter, and is provided with an opening, the edge of the opening is hermetically connected with the edge of the entrance, and a movable sliding plate which is used for closing the entrance is arranged at the opening. The sliding plate is arranged at the opening and movably mounted. The sliding plate can move to close the opening or avoid the opening. The edge of the opening is hermetically connected with the edge of the entrance, so that the opening becomes an extended opening of the entrance of the air inlet pipe of the air filter; and when the opening is closed by the sliding plate, the entrance of the air inlet pipe of the air filter is closed, so that the air for the engine to combust is isolated, the engine is in flameout, and the security of the vehicle is guaranteed.

Description

Technical field [0001] The invention relates to a braking technology, in particular to a braking device for preventing throttle failure. Background technique [0002] The three basic elements of internal combustion engine operation are: fuel, ignition timing and air. [0003] In the era of cable throttle, fuel and ignition timing are controlled by electronic equipment, and air is controlled by a cable connected to the accelerator pedal. Only when the accelerator pedal is depressed can air enter the engine. The cable throttle is directly connected to the throttle, which reacts quickly, but is not smart enough and not accurate. [0004] In recent years, with the demand for automobile intelligence and energy saving and emission reduction, electronic accelerators have been widely used in various vehicles. Electronic accelerators use wire harnesses instead of cables. The accelerator pedal is no longer directly connected to the throttle, but connected to a sensor. Calculate the sensor va...

Problems solved by technology

[0006] The invention solves the defect that the electronic throttle in the prior art is inevitably out of control due to the complex structure of the electronic system, which causes the electronic throttle to be unable to control the combustion and air intake of the engine, which makes the vehicle have safety risks, and provides a braking device for preventing the failure of the throttle , at the inlet of the air filter intake pipe, a movable slide plate is set. After the electronic throttle fails, the intake pipe entrance is closed by controlling the slide plate, and the engine combustion air is cut off, so that the engine is turned off, the vehicle is braked, and the safety of the vehicle is ensured.
