A hydraulic suspension device for an intelligently controlled all-electric multi-wheeled mobile platform

Abstract

The invention relates to the field of new concept electric vehicles, specifically to an intelligently controlled hydraulic suspension device for a full-electric multi-wheel mobile platform. The intelligently controlled hydraulic suspension device for the full-electric multi-wheel mobile platform comprises a tapered roller bearing inner ring and a tapered roller bearing outer ring which are respectively in rolling fit with a roller; the top end of the tapered roller bearing outer ring extends inwards and is fixedly connected with a housing of an electric motor; the interior of the tapered roller bearing inner ring extends inwards and is fixedly connected with an output end of the electric motor; the output end of the electric motor can control relative rotation between the tapered roller bearing inner ring and the tapered roller bearing outer ring; and at least one electromagnetic pin, which is limited by and separated from the tapered roller bearing outer ring is arranged at the top ofthe tapered roller bearing inner ring. According to the intelligently controlled hydraulic suspension device for the full-electric multi-wheel mobile platform, as an elastic material rigid protectionsleeve structure is adopted, a buffering and shock absorbing effect on the hydraulic device is realized; and meanwhile, a problem that slight shaking of the surrounding of a hydraulic rod caused by transverse force generated in the working process of the hydraulic device is effectively solved.

Description

technical field [0001] The invention relates to the field of new-concept electric vehicles, in particular to a hydraulic suspension device for an intelligently controlled all-electric multi-wheel mobile platform. 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 (tha...

AI Technical Summary

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.
