Multi-wheel type hydraulic suspension intelligent control full-electric movable platform

Abstract

The invention relates to the field of new-concept electric vehicles, in particular to a multi-wheel type hydraulic suspension intelligent control full-electric movable platform. The multi-wheel type hydraulic suspension intelligent control full-electric movable platform is characterized in that a controller and speed sensors are arranged on the top of movable platform chassis, the running speeds of the movable platform chassis can be monitored by the speed sensors in real time, distance sensors and image sensors are arranged at the bottom of each tapered roller bearing inner race, angle sensors are arranged on the top of each tapered roller bearing inner race, and rotational speed sensors are arranged on each electric vehicle wheel and are used for monitoring the rotational speeds of the electric vehicle wheel. The multi-wheel type hydraulic suspension intelligent control full-electric movable platform has the advantages that the ground grip capacity can be enhanced by the multiple vehicle wheels, accordingly, the multi-wheel type hydraulic suspension intelligent control full-electric movable platform can effectively adapt to complicated road surfaces, rollover risks can be prevented even if a few wheels are damaged, and a vehicle can run to maintenance places without being affected; the multiple hydraulic suspension electric vehicle wheels are structurally and functionally consistent with one another, and the maintainability and the interchangeability of the multi-wheel type hydraulic suspension intelligent control full-electric movable platform with a multi-wheel structure can be improved as compared with the traditional four-wheel structure.

Description

technical field [0001] The invention relates to the field of new-concept electric vehicles, in particular to an intelligently controlled all-electric mobile platform with multi-wheel hydraulic suspension. Background technique [0002] Automobile is a kind of daily transportation with relatively mature technology, and it is a typical mobile platform. In recent years, electric vehicles or pure electric vehicles have attracted people's attention and developed rapidly. They use batteries as energy storage power sources, and provide electric energy to motors through batteries. Drive the electric motor to run, so as to drive the car; some of these electric vehicles only replace the fuel with the battery, and the internal combustion engine with the electric motor, and still use mechanical transmission, following the "power-transmission-action" energy transmission link, and some pure electric vehicles use Electric transmission, directly combining the motor and the wheel (that is, th...

Problems solved by technology

Existing cars generally have 4 or more wheels, which have relatively good comfort and speed. However, compared with tracked vehicles, wheeled vehicles have poor passability in complex road conditions and relatively high requirements for road conditions. Moreover, although the existing vehicles have a suspension system, the length of the wheels perpendicular to the road surface is limited, and the driving on the uneven road surface is easily restricted; the tracked vehicle is a typical special vehicle, and the track is equivalent to a self-paved road. For example, crawler vehicles such as excavators have good passability in complex road conditions on soft roads or uneven roads. The track is driven by the driving wheel and is surrounded by flexible chains around the driving wheel, road wheels, induction wheels and supporting pulleys. Track pins The track shoes are connected to form a track link. As we all know, the link structure is equivalent to multiple tracks connected in series, so once the track of a tracked vehicle fails (any track shoe breaks or falls off), the vehicle will not be able to drive.
