Vehicle motor with differential and braking functions

Abstract

The invention provides a vehicle motor with differential and braking functions, and belongs to the technical field of vehicles. Comprising a shell, a first half shaft and a second half shaft, the first half shaft and the second half shaft are coaxial, a mounting frame is rotationally connected into the shell, a permanent magnet rotor is arranged on the mounting frame, an excitation stator matched with the permanent magnet rotor is arranged on the inner wall of the shell, power is input into a flywheel through a driving motor arranged on a frame, and differential is achieved through a differential mechanism structure. The first differential bevel gear and the second differential bevel gear can be controlled to be combined with the shell, so that rotation of the mounting frame is converted to the first differential bevel gear or the second differential bevel gear, and power distribution of the first half shaft and the second half shaft is achieved. And meanwhile, the first differential bevel gear and the second differential bevel gear are combined with the shell, so that stopping and braking of the mounting frame can be achieved. The system has the advantages of being simple in structure, integrating multiple functions needed by the vehicle and the like.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and relates to a vehicle motor with differential speed and braking functions. Background technique [0002] In the detection process of unknown or harsh environments such as fire sites, large-scale pipe corridors with potential safety hazards, and extremely cold areas, unmanned equipment is often required to replace manual remote detection to collect various data of the environment, and to rescue, Provide basis for follow-up work such as maintenance. [0003] In order to obtain more data, unmanned detection tools need to carry a large number of sensing devices. The longer battery life of unmanned detection tools also requires larger energy storage devices, while the walking, steering, and obstacle crossing of unmanned detection vehicles The basic function can complete the basic conditions of the detection function. How to make the unmanned detection vehicle as simple as possible, with a small s...

AI Technical Summary

Problems solved by technology

[0005] Traditional probe cars generally have a dual-motor structure. The two motors control the two steering wheels respectively. Walking, steering and obstacle surmounting are realized by controlling the respective speeds of the motors. However, this structure has poor performance in terms of road adaptability. The logic is complex, a large number of ineffective transmissions are formed during the passive differential of the two steering wheels, and the power is wasted seriously. Poor, complex structure
