Planetary type triangular crawler running and driving device

Abstract

The invention discloses a planetary type triangular crawler running and driving device. The planetary type triangular crawler running and driving device is mainly used for vehicles which perform scout, transportation or combat along with soldiers under the environment with complex terrain, many obstacles and dangerous circumstances. The planetary type triangular crawler running and driving deviceis mainly composed of a rocker arm, a triangular supporting frame, gears, a driving motor, transmission devices, hydraulic cylinders, driving wheels and a crawler. The rocker arm is fixed to movable devices such as a vehicle body and supported, the driving motor transmits power to the driving wheels through the gears and the transmission devices, and the driving wheels mesh with the crawler to drive the integrity to move forward. According to the planetary type triangular crawler running and driving device, the triangular supporting frame and the rocker arm are connected through bearings and under a free rotating state, when the crawler meets an obstacle, the triangular supporting frame can overturn freely, the crawler is tightly attached to the obstacle to maintain the ground gripping force or overturn the obstacle, and the whole running device has the high terrain adapting capacity; and meanwhile, when the crawler is broken and fractured, the planetary type triangular crawler runningand driving device can still run under a wheel state due to the fact that the driving wheels have power.

Description

technical field [0001] The invention belongs to the technical field of walking and driving of special vehicles, and in particular relates to a planetary triangular crawler walking and driving device. Background technique [0002] Military ground vehicles are often used as combat outposts in practical applications, and their accessibility and passability in dangerous and harsh environments are essential performances for their missions. The obstacle-surmounting ability and vehicle stability of military ground vehicles mainly depend on the walking and driving devices. However, due to the harsh environment of military ground vehicles, when encountering obstacles such as large obstacles, slopes, ditches and vertical walls, the traditional Walking and driving devices cannot well solve the problems of environmental diversity, complexity and unpredictability in actual use. Contents of the invention [0003] The invention provides a planetary triangular crawler walking and driving...
