Automatic guiding transport cart and driving steering mechanism thereof

Abstract

The invention discloses a driving steering mechanism. The driving steering mechanism comprises a shock-proof assembly, a rotary load bearing assembly and a chassis component, the shock-proof assembly comprises an upper mounting plate and a lower mounting plate which are arranged in a stacked mode and can move oppositely up and down, the lower mounting plate is provided with a center hole, and a rotation angle feedback device, multiple shock-proof springs and a limiting pillar used for limiting the largest spacing between the upper mounting plate and the lower mounting plate are arranged between the upper mounting plate and the lower mounting plate; the rotary load bearing assembly comprises a rotary shaft and a rotary shaft fixed base which penetrate through the center hole and are coaxially and rotatably matched, steering synchronous wheels are coaxially and fixedly connected to the upper end of the rotary shaft, the lower end of the rotary shaft is fixedly connected with the chassis component, and the rotary shaft fixed base is fixedly connected with the lower mounting plate. According to the driving steering mechanism, on the condition of not influencing driving and transportation, the structural complexity of the driving steering mechanism is lowered, the mechanism size is reduced, and a low and short field work environment can be adapted to in the traction and transportation process. The invention further discloses an automatic guiding transport cart which comprises the driving steering mechanism.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to an automatic guided transport vehicle and its driving and steering mechanism. Background technique [0002] Automatic guided transport vehicle (AGV for short) is a transport vehicle equipped with electromagnetic, optical and other automatic guidance devices, capable of driving along the prescribed guiding route, with safety protection and various mobile loading functions, belonging to the category of wheeled mobile robots . In order to adapt to the working environment with small moving space and small steering space, the driving mechanism and the steering mechanism are generally integrated into an integrated structure, and the steering methods are generally divided into independent deflection wheel type, differential drive type and Mecanum wheel type, etc. It can realize the all-round steering function of AGV, but the load capacity of the independent deflection wheel type ...
