Automobile clutch and accelerator linking device

Abstract

The invention discloses an automobile clutch and an accelerator linking device. An upper end of a buffer oil cylinder is connected with the upper and lower ends of a pedal rod of a clutch through a connecting rod; an adjusting lever is movably connected with a vehicle frame; an upper end of a servo oil cylinder is movably connected to the pedal rod of an accelerator through a plunger piston, and the lower end of the servo oil cylinder is connected with the adjusting lever and movably connected to the vehicle frame; and a lower oil chamber of the buffer oil cylinder is communicated with a lower oil chamber of the servo oil cylinder through an oil pipe. When the clutch is stepped on for a gear change, a slide valve in the buffer oil cylinder is pushed to a lower dead center; oil in the lower oil chamber is discharged to an upper part and is pressed down the lower oil chamber of the servo oil cylinder through the oil pipe; and an oil pipe passage is closed at the same time, so that the oil is accumulated in the lower oil chamber of the plunger piston to prevent the accelerator from being stepped on. After the gear change, the buffer oil cylinder restores the clutch based on the technical requirements of fast-slow-fast so as to avoid the phenomenon that the clutch is closed too fast; and an accelerator pedal connected with the servo oil cylinder enables the clutch to be well matched with the accelerator along with the actions of the clutch and the buffer oil cylinder for fuelling.

Description

technical field [0001] The invention relates to a gear shift acceleration and oil supply device of an automobile, in particular to a linkage device for increasing the throttle when the automobile shifts into gear. Background technique [0002] Nowadays, when a car with manual transmission shifts gears too quickly or for beginners, the coordination between the accelerator and the gear position is often not good, so that the output power of the engine cannot keep up with the torque required by the axle for a short time, which will cause the engine to seriously overshoot for a short time. load, causing vibrations and unpleasant noises, and even stalling the engine. The main reason for this phenomenon is that the left leg of stepping on the clutch is lifted too fast when the clutch is released, and the switch is closed too fast, resulting in engine overload and flameout. When the clutch is pressed to change gears, if the gas pedal is not properly stepped on, the engine speed wi...

[0002] Nowadays, when a car with manual transmission shifts gears too quickly or for beginners, the coordination between the accelerator and the gear position is often not good, so that the output power of the engine cannot keep up with the torque required by the axle for a short time, which will cause the engine to seriously overshoot for a short time. load, generate vibrations and unpleasant noises, and even cause the engine to stall

The main reason for this phenomenon is that the left leg of stepping on the clutch is lifted too fast when the clutch is released, and the brake is closed too fast, resulting in engine overload and flameout

When the clutch is pressed to change gears, if the gas pedal is not properly stepped on, the engine speed will be too high, making an unpleasant humming sound, and the fuel consumption will increase.
