Abstract

An obstacle surmounting mechanism with integration of wheel track and oscillating arm is provided with a wheel track transmission mechanism arranged on the lower part of a frame (8). The wheel track transmission mechanism comprises a front belt wheel (4) which is arranged on the front lower part of the frame (8) with the lower edge of the front belt wheel (4) higher than that of a guide wheel (7), and a rear belt wheel (2) which has a smaller wheel diameter than that of a rear wheel (15) and is arranged on a rear wheel spindle (1) through a bearing, wherein the front and rear belt wheels (4,2) are driven by a track (3), and the axle of the front belt wheel (4) is driven by the obstacle surmounting mechanism (14). An oscillating arm mechanism is arranged on the upper part of the frame (8). The oscillating arm mechanism comprises an oscillating arm (11) which is hinged onto the frame (8), an oscillating gear (10) which is connected with the cardinal axis (16) of the oscillating arm (11) and meshes with the output gear (5) of an obstacle surmounting motor (14) arranged on the frame, and an oscillating arm wheel (12) which is arranged on the other end of the oscillating arm (11). The mechanism has a simple structure, high obstacle clearance, powerful driving, stable obstacle surmounting and flexible operation on the flat land.

Description

technical field [0001] The invention relates to an obstacle-surmounting mechanism. Background technique [0002] Existing obstacle-climbing mechanisms can be broadly divided into wheeled and crawler-type. The wheeled obstacle-climbing mechanism mainly utilizes the working principle of the center wheel train, and its application is mainly in the field of robotics. But for the straight slope of big slope such as 90 degrees, and when the obstacle is higher, the center wheel train mechanism is just powerless. The crawler-type obstacle-climbing mechanism uses the track to contact the obstacle, and then adjusts the center of gravity of the vehicle through the transformation of the wheel train, and uses a high-power driving source to drive to achieve obstacle-crossing. It is mainly used in military and high-power construction machinery. Because the track is in direct contact with the ground, the contact area is relatively large, and the frictional force is relatively large, so t...
