Abstract
The utility model discloses a steering system for electric vehicles, relates to a steering system for two-axle four-wheeled electric vehicles, and aims to overcome defects that existing two-axle four-wheeled electric vehicles always utilize mechanical steering systems and are complicated in structure, high in cost and high in dead weight. The steering system for the two-axle four-wheeled electric vehicles is full-automatic in structure and programing in operation, comprises a front axle and a back axle or a front left half axle, a front right half axle, a back left half axle and a back right half axle, a left front wheel, a right front wheel, a left back wheel, a right back wheel, and drive motors corresponding to the different wheels. Rotation planes of the wheels are perpendicular to mounting shafts of the corresponding wheels. The front axle and the back axle are in parallel and mounted fixedly, the wheels driven by the motors are mounted in a bilaterally symmetrical manner, the different motors drive the corresponding wheels by means of gear transmission, belt transmission, friction transmission and chain transmission, or the corresponding wheels are driven by hub motors.
Description
(1) technical field
The utility model relates to a kind of steering system of diaxon four-wheel electric motor car.Be a kind of pure electron steering battery-driven car steering system, save steering control mechanism, deflector and the steering gear of manual steering system.
(2) background technology
Present diaxon four-wheel electric motor car mostly is manual steering system, comprises steering control mechanism, deflector and steering gear, has complex structure, and cost is high, from great shortcoming.
(3) summary of the invention
Shortcoming and deficiency in view of this type of diaxon four-wheel electric motor car steering system, the purpose of this utility model provides a kind of pure electron steering diaxon four-wheel electric motor car steering system, it is parallel all the time when the front axle of battery-driven car is turned with rear axle, remove steering control mechanism, deflector and the steering gear of manual steering system, structure can all electronic, steering program, cost is low, from advantages such as heavy and lights.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of steering system of diaxon four-wheel electric motor car, by front axle and rear axle, perhaps front left half axle, front right axle shaft and rear left half axle, rear right axle shaft, and the near front wheel, off front wheel and left rear wheel and off hind wheel, and driving motor corresponding to each wheel forms.The plane of revolution of each wheel is perpendicular to the installation shaft of this wheel.Front axle and rear axle parallel relation and fixed installation, perhaps front left half axle, front right axle shaft and rear left half axle, rear right axle shaft all is parallel relation and fixed installation, front axle and rear axle can be rotating shafts, stationary spindle, mandrel, when front axle or rear axle are rotating shaft, front axle is divided into front left half axle and front right axle shaft, rear axle is divided into rear left half axle and rear right axle shaft, and each semiaxis independent rotation, when front axle or rear axle are stationary spindle, front axle is divided into front left half axle and front right axle shaft, and rear axle is divided into rear left half axle and rear right axle shaft, and each semiaxis independent rotation, when front axle or rear axle are mandrel, the near front wheel and off front wheel share front axle, and left rear wheel and off hind wheel share rear axle, and perhaps front axle is divided into front left half axle and front right axle shaft, rear axle is divided into rear left half axle and rear right axle shaft, and each semiaxis independent rotation.Front axle or front left half axle, front right axle shaft support separate rotation or the separately-driven the near front wheel of electrical motor and off front wheel, and rear axle or rear left half axle, rear right axle shaft support separate rotation or the separately-driven left rear wheel of electrical motor and off hind wheel.The separately-driven wheel of electrical motor is that the left-right symmetric relation is installed, can be that electrical motor drives respectively the near front wheel and electrical motor drives respectively the off hind wheel combination, can be that electrical motor drives respectively left rear wheel and electrical motor drives respectively the off front wheel combination, can be that electrical motor drives respectively the near front wheel and electrical motor drives respectively the off front wheel combination, can be that electrical motor drives respectively left rear wheel and electrical motor drives respectively the off hind wheel combination, also can be that four-wheel is all driven respectively combination by electrical motor.Each electrical motor transmits with gear, and the mode of belt transport, friction transmission, chain transmission drives corresponding wheel, perhaps uses wheel hub electric motor to drive corresponding wheel.
The principle of work of this battery-driven car steering system is very simple, front axle is parallel all the time with rear axle, when the momentary velocity of left side wheel during greater than the momentary velocity of right side wheels, be the travel cireular frequency of cireular frequency greater than right side wheels that travel of left side wheel, then battery-driven car bends to right, otherwise turn left, when the cireular frequency that travels of left and right sides wheel equates, the battery-driven car straight-line motion.
The beneficial effects of the utility model are, the utility model removes steering control mechanism, deflector and the steering gear of manual steering system, and structure can all electronic, steering program, and cost is low, from advantages such as heavy and lights.
(4) description of drawings
Fig. 1 is the electric vehicle chassis birds-eye view that four wheel hub electric motors of the utility model drive.
Fig. 2 is two electric motor driven electric vehicle chassis birds-eye vieies of the utility model.
Among the figure, 1. front right axle shaft, 2. right rear wheel, 3. left front electrical motor, 4. gear.
(5) specific embodiment
With Fig. 2 example, front left half axle and rear right-hand rotation semiaxis are the power output revolving shafts, are subjected to separately direct motor drive, and with the form transmission torque of gear transmission, front right axle shaft and rear left half axle are stationary spindles, freely rotated by force of rolling friction control.Control respectively the rotating speed of two electrical motors by motor controller, and then the speed discrepancy of control the near front wheel, off hind wheel, just can control easily battery-driven car about turning and straight-line travelling.In view of the wearing and tearing of ground in the face of rubber tire, the driving motor instantaneous power, the utility model technology more is applicable to toy for children or battery-driven car model.
