Damping type car gear shifting variable-speed control mechanism

Abstract

The invention provides a novel damping type car gear shifting variable-speed control mechanism. The novel damping type car gear shifting variable-speed control mechanism comprises a cardan joint crossbearing, a fixed base, a control rod assembly, a gear selecting swing arm assembly, a selector shaft assembly, a selector shaft, a damping block and a flexible shaft fixing support. The novel dampingtype car gear shifting variable-speed control mechanism is characterized in that the cardan joint cross bearing serves as a rotary center motion component, a motion relation is generated by the cardan joint cross bearing, the control rod assembly, the selector shaft assembly and the gear selecting swing arm assembly, a control flexible shaft is approximately pushed and pulled linearly, and the problem that after the control mechanism with a control rod and a gear shifting arm connected selects gears left right to swing, swings front and back to shift the gears, and consequently a gear shifting stay wire at the position where a flexible shaft is fixed suffers from fatigue cracking due to the too large tilt angle is solved. A gear shifting damping device is arranged between the selector shaft and a base and achieves a gear shifting damping function to increase the clear sense of gear shifting gears.

Description

technical field [0001] The invention relates to an automobile gear selection and shifting control mechanism. Background technique [0002] With the continuous progress and development of the automobile industry, people have higher and higher requirements on the performance of automobile transmission control. In the current car gear selection and shifting control mechanism, the joystick is connected to the gear shifting arm, and the gear is shifted back and forth after swinging left and right, resulting in an excessive swing angle of the gear shifting flexible shaft, which makes the cable where the flexible shaft is fixed easily fatigued and broken; At the same time, when shifting gears, the gear sense is not clear, the handling comfort is poor, and the structure fails or the reliability is reduced. Contents of the invention [0003] The present invention proposes a damping type gearshift and speed change control mechanism, which uses a universal joint cross bearing as a r...
