Abstract

Said invention discloses non-steering wheel double cross arm guide mechanism for eliminating additional steering interference generated by vertical bouncing of wheel, which consists of frame, upper cross arm, kunckle and wheel etc wherein one end of upper cross arm in hinged with frame by fixing pin, another end is hinged with knuckle by ball joint.

Description

technical field [0001] This invention relates to a vehicle mechanism and, more particularly, to a double wishbone suspension guide mechanism utilizing non-steering wheels that does not produce additional steering. Background technique [0002] With the improvement of people's living standards, cars are used more and more widely, and people's requirements for cars are getting higher and higher, and the development of cars is developing in the direction of comfort and light weight. The driving form of traditional vehicles is driven by internal combustion engines. In recent years, electric vehicles and hybrid vehicles have developed rapidly. The existing driving schemes of vehicle power include series, parallel and hybrid. There are pros and cons to layout, price, and prime mover selection. Four-wheel drive electric vehicles can directly drive each wheel with four electric drive wheel modules with the same structure, but in a two-wheel steering four-wheel drive electric vehicl...
