Rope-driven automobile gear shifting robot

Abstract

The invention relates to the technical field of robot automatic driving, and discloses a rope-driven automobile gear shifting robot which comprises a gear shifting rod. A gear shifting rod clamp is arranged at the bottom of the gear shifting rod, a steel wire rope is arranged at the bottom of the gear shifting rod clamp, and a motor and winding drum assembly is arranged at one end of the steel wire rope. The motor and winding drum assembly comprises a first motor winding drum, a second motor winding drum, a third motor winding drum and a fourth motor winding drum, motor bases are arranged at the bottoms of the first motor winding drum, the second motor winding drum, the third motor winding drum and the fourth motor winding drum correspondingly, a base plate is arranged at the bottoms of the motor bases, and a base plate clamping device is arranged at the bottom of the base plate. According to the rope-driven automobile gear shifting robot, the winding drums are driven through four motors correspondingly, then torque is transmitted to the gear shifting rod through the steel wire rope, gear shifting operation is achieved, the device can actively control the spatial three-translational motion freedom degree of the head of the gear shifting rod, the device can be matched with the H-type gear shifting form, control is accurate, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of robot automatic driving, in particular to a cable-driven automobile shifting robot. Background technique [0002] With the development trend of new technologies in the automobile industry, people have put forward higher and higher requirements for the safety and reliability of automobiles, which requires enterprises to do a lot of stability, safety, reliability and durability tests on automobiles. Continuously improving the level, compared with human drivers, self-driving robots have the advantages of high-precision control, good repeatability, and strong fatigue durability. The car shifting robot can accurately collect the data of the car shifting mechanism, eliminate the influence of human drivers on the test results due to differences in driving skills, and improve efficiency. Therefore, it is widely used in vehicle dynamic testing, vehicle operation stability and Shift mechanism life test. [0003] ...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the existing automatic shifting devices for automobiles have problems such as low precision, damage to the original car structure, complicated installation, and bulky volume. At the same time, the existing devices may affect the driver's manual operation and even completely fail to operate after the shifting device is installed. Manual gear shift operation increases the safety hazard during vehicle testing
