Embodiment Construction

[0011] exist figure 1 , slide the joystick to the right to put the mechanism into the direct drive gear, and the meshing sleeve meshes with the direct drive drive gear. At this time, the power is from the direct drive drive gear nested on the drive shaft through the direct drive gear fixed to the differential housing. The driving driven gear is transmitted to the differential, and the differential drives the left and right half shafts to rotate at the same speed and direction, thus realizing the direct driving condition.

[0012] exist figure 2 , slide the joystick to the left to put the mechanism into the center steering gear, and the meshing sleeve meshes with the center steering driving gear. At this time, the power is steered from the center steering driving gear nested on the driving shaft through the center fixedly connected to the left half shaft. The driven gear is transmitted to the left half shaft; at the same time, the shift fork is engaged and locked with the dir...

Abstract

A mechanical differential drive mechanism mainly comprises a shift fork, a meshing sleeve, driving and driven gears for straight drive position and a central steering position, a differential, a half shaft, a structural support, and the like. The mechanical differential drive mechanism has the advantages of simple structure, fine machinability, low cost, operational reliability and wide range of application. Different positions of the shift fork allow for the linear drive position and the central steering position; operation is facilitated; manual or electric operation is available. The mechanical differential drive mechanism is especially suitable for central-steering AGVs, central-steering EOD robots, special electric buses, electric tracked vehicles, electric wheelchairs for disabled people, and electric medical tables.

Description

technical field [0001] The invention relates to a mechanical center steering mechanism for a center-steering AGV logistics vehicle, a center-steering explosion-proof robot and an electric wheelchair for disabled persons. Background technique [0002] In the past, center-steering AGV logistics vehicles, robots, track-driven vehicles, and wheelchairs for the disabled mostly used dual-motor-driven differential steering modes. This type of layout scheme can increase the driving flexibility of the body and can control the driving trajectory of the body. Precise control. However, since the driving conditions of products such as center-steering AGV logistics vehicles are extremely simple, including only straight-line driving and in-situ center steering conditions, the dual-motor layout and relatively complicated control system make the manufacturing cost relatively high, which is not suitable for large-scale vehicles. Popularity of scale. Contents of the invention [0003] The ...
