Gear shifting push-pull cable and automobile

Abstract

The invention discloses a gear shifting push-pull cable. The gear shifting push-pull cable comprises a mounting framework, pistons and a pull cable; an accommodating cavity is formed in the mounting framework; the pistons are arranged in the accommodating cavity in a sliding mode, and a liquid storage cavity used for accommodating hydraulic oil is isolated in the accommodating cavity; one sectionof pull cable penetrates through the first end of the mounting framework, one end of the pull cable is connected with one, close to the first end, of the multiple pistons, and the other end of the pull cable is used for being connected with a transmission gear-shifting rocker arm; and the other section of pull cable penetrates through the second end of the mounting framework, one end of the pull cable is connected with one, close to the second end, of the multiple pistons, and the other end of the pull cable is used for being connected with a shifter gear-shifting rocker arm. The invention further discloses an automobile which comprises the gear shifting push-pull cable. Movement synchronism of the two sections of pull cables is guaranteed through the hydraulic oil and the pistons in the accommodating cavity, and the situation that a gear cannot be engaged due to asynchronous movement of the two sections of pull cables is avoided; two-way transmission of vibration between a gear shifter and a transmission is achieved; and high-frequency low-pair vibration can be converted into heat energy of the hydraulic oil, so that transmission of vibration and noise is blocked, and the gear shifting hand feeling is optimized.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to a shift push-pull cable and an automobile. Background technique [0002] At present, the shift control system uses a mechanical shift cable to transmit the force and stroke transmitted by the driver through the shifter; the mechanical shift cable includes a mounting plate, a cable protection tube assembled on the mounting plate, and a The cable core wire in the lumen of the cable protection tube, the cable core wire can freely slide back and forth in the cable protection tube, and the two ends of the cable core wire are respectively connected to the transmission shift rocker arm and the shifter shift rocker arm ; The mechanical shift cable has the following disadvantages: [0003] The vibration of the powertrain due to the power output will be transmitted from the transmission shift rocker to the shift rocker of the shifter through the cable core wire, which will cause vibration and n...
