Electric automobile transversal travel and clockwise counter-clockwise rotation body steering mechanical drive technology

Abstract

The present invention relates to an electric automobile transversal travel and clockwise counter-clockwise rotation body steering mechanical drive technology. The driving of the electric vehicle is completed by that four wheels are respectively provided with a tributary brushless hub motor or a column-typed motor (the power is generally ranging from 750w to 3000w or arranged according to the design requirement of the manufacturer); a steering wheel is rotated to drive a gear and rack steering gear and link a leading screw (the left half part of the leading screw is a positive thread, the right half part thereof is a reverse thread and the middle part thereof is a turbine reducer); the leading screw respectively drives a thread sliding block which is linked to a left direction steering rod and a right direction steering rod so as to transmit the steering to a left wheel and a right wheel, thus gaining the steering function. When the transverse rotation advancing is required, the turbine reducer drives two thread sliding blocks to motion to two sides simultaneously, thus gaining the required rotation angle: -90 DEG or 45 DEG or -60 DEG (which is controlled according to the angle artificially required by a photoelectric coupling sensor and a position limiting switch), thus gaining the objects of transverse movement or rotation. When the normal driving is required by the automobile, two motors of the front axle and the rear axle drive a worm wheel and a worm to rotate reversely, two leading screws slide back to the initial position, wheels recover to normal position, the power supply of the steering motor is locked and turned off, and the controller is operated so as to lead the automobile to recover to the normal driving state.

Description

technical field [0001] The invention relates to a steering control method and a device thereof for an electric vehicle, in particular to a steering control method and a device thereof for realizing lateral travel and in-situ rotation of an electric vehicle. Background technique [0002] This is the golden age for the development of electric vehicles in my country. Recently, international energy prices have skyrocketed, and international futures crude oil has approached the $100 mark per barrel. This fully shows that energy reserves are decreasing day by day. The storage capacity is on the verge of depletion, but the unrestrained production of oil-consuming machines-cars (a billion vehicles in the world) increases the emission of greenhouse gases in the atmosphere, thus causing the earth's environment and temperature to deteriorate rapidly. It has brought unprecedented opportunities to the diversified utilization of international energy and the development of renewable energy. ...
