Travelling steering mechanism for electric vehicle

Abstract

The invention discloses a travelling steering mechanism for an electric vehicle and belongs to the technical field of electric vehicle designing and manufacturing. The electric vehicle functions of rotating on the spot and travelling transversely and obliquely can be achieved through the travelling steering mechanism. The lower end of a steering wheel assembly is provided with a first gear engaged with a front rack. First connecting rods are hinged to the two ends of the front rack correspondingly. A front transverse beam and a back transverse beam are arranged at the two ends of two side longitudinal beams of a chassis. The middles of the two side longitudinal beams are provided with a middle shaft. The middle of the middle shaft is provided with a driven gear engaged with a driving gear. The upper portion of the opening end of each coupling is hinged to a corresponding wheel hub steering part. The couplings are hinged to through holes in the two ends of the front transverse beam and the two ends of the back transverse beam. The other end of each coupling is hinged to the corresponding first connecting rod. The middles of driving connecting rods are fixed to the middle shaft. The two ends of each driving connecting rod are hinged to one ends of second connecting rods. The other ends of the second connecting rods are hinged to one ends of third connecting rods. The other ends of the third connecting rods penetrate through positioning holes and are fixed to rack sleeves. The travelling steering mechanism is mainly used for the electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle design and manufacture. Background technique [0002] With the rapid consumption of fossil fuels such as oil and natural gas, and the resulting energy crisis and environmental pollution, the development and utilization of new, clean and safe renewable energy and the reduction of pollution emissions have become global concerns Two focal points. The development of automobiles has not only increased the consumption of earth resources, but also increased pollution emissions. As a big country in the world, our country suffers from shortage of resources and environmental pollution. Therefore, the development of electric vehicles has become an inevitable trend in the development of the automobile industry, and the recent nationwide smog phenomenon has increased this call. The development of electric vehicles is conducive to alleviating the shortage of resources and environmental pollution, so...
