Problems solved by technology

[0004] Existing vehicles use a unified steering mechanism and differential drive mode in conjunction with the double wishbone structure. The turning radius is relatively large, and in-situ steering cannot be realized, so it is not suitable for wheeled robots.

Abstract

The invention relates to a four-wheel independent steering mechanism including a chassis and traveling wheels, the traveling wheels comprise a front traveling wheel and a rear traveling wheel, the chassis is connected with a bearing seat through a double fork arm structure, A drive shaft is passed through the bearing housing, the transmission shaft is fixedly connected with a traveling wheel, eachof the drive shafts is connected with a drive mechanism, each of the traveling wheels is connected with a steering mechanism, the number of the driving mechanism and the steering mechanism is the same as the number of the traveling wheels, Each of the traveling wheels correspondingly connects a driving mechanism and a steering mechanism to realize independent driving and independent steering of the traveling wheels. The traveling wheel of the invention adopts independent driving and independent steering, can realize small radius turning and in-situ rotation, has strong passing ability and flexibility, and meets the requirements of wheeled robot.

Description

technical field [0001] The invention relates to the technical field of wheeled robots, in particular to a four-wheel drive independent steering mechanism. Background technique [0002] Wheeled robots on the market need to work in an outdoor environment. They need to have strong passability and flexibility, and require the ability to overcome obstacles on complex road surfaces. They can achieve a small turning radius and can rotate in place. [0003] The double-wishbone structure used in the existing vehicle driving system has large lateral rigidity, excellent anti-rolling performance, good grip performance, and clear road feeling. [0004] Existing vehicles use a unified steering mechanism and differential drive mode in conjunction with the double wishbone structure. The turning radius is relatively large, and in-situ steering cannot be realized, so it is not suitable for wheeled robots. Contents of the invention [0005] The purpose of the present invention is to overcom...
