The three-wheeled automobile is characterized in that the hydraulic motor of the driving device is directly fixed on two back wheels, is connected with the back wheel vibration absorber (the oil pump) and is installed on the rear axle two ends of which are in a dragging arm type. In the invention, a brushless motor drives a main oil pump to supply oil to a closed hydraulic system to control the hydraulic motor to drive the back wheels at two ends of the automobile to rotate, thus eliminating a gearbox, a transmission shaft, a half shaft and a differential mechanism, simplifying the driving structure and improving transmission efficiency. The invention has the advantages of simple transmission structure, high efficiency, low production and usage cost, safety, comfortableness, practicability, low-carbon energy saving, environment protection, elegant shape, simple and economic operation, reasonable performance configuration and the like, thus being an ideal micro-hydraulic three-wheeled automobile.
Description
Technical field
The present invention relates to automobile, especially relate to a kind of miniature hydraulic three-wheeled automobile.
Background technology
As everyone knows, because non-renewable energies such as current coal oil is exhausted day by day, with improving constantly of people's low-carbon economy environmental consciousness, and various countries develop various carbon-free clean energy resourcies such as solar power, wind energy, geothermal energy in recent decades, and various countries formulate in the development program of long-range electronlmobil, gradually reduce instead of gasoline car, diesel-powered vehicle and also become trend of the times.
The productive costs of current common electric automobile is more than 20,000 yuan, select for use motor power (output) about 3 kilowatts, hundred kilometers consumption of currents are more than 10 degree, the maintenance cost in battery every year of now using is also quite high, the specification of its vehicle minimum is: long 3000 millimeters, wide 1400 millimeters, high 1450 millimeters, most of structure adopts the type of belt drive of mid-motor; By change speed gear box, transmission shaft, diff, semiaxis, be connected with back axle, identical with automotive transmission, structure and complicated and consumed a part of kinetic energy not only by dress, drive efficiency is low, productive costs and use cost be all than higher.
Summary of the invention
The object of the present invention is to provide a kind of actuating device simple, the driving efficiency height, productive costs and use cost are all very low, and having advantages such as safety and comfort practicality, low-carbon energy-saving environmental protection, generous, simple to operate economy handsome in appearance, performance configuration be reasonable is that a kind of 3 desirable people sit miniature hydraulic three-wheeled automobile.
The object of the present invention is achieved like this: a kind of miniature hydraulic three-wheeled automobile comprises vehicle body, steering hardware, lighting instrument handling device, front vehicle wheel swing arm type shock absorber (oil pump), travels and braking control system, chassis, closed fhdraulic system accumulator, rear wheel shock absorber (oil pump), actuating device, two-port valve, brushless motor, main oil pump, three-position valve, direction valve, fluid power motor.It is characterized in that the actuating device fluid power motor directly is fixed on two rear wheels, drag on the back axle of arm pattern with the holder of rear wheel shock absorber (oil pump) connection at both ends.This car in the process of moving, the pressure oil that front and back shock absorber (oil pump) up-and-down movement produces, the pressure oil that produces during the fluid power motor brake all deposits in the closed fhdraulic system accumulator.When this car need start: the operation two-port valve was connected the pressure oil in the closed fhdraulic system accumulator earlier, directly reaching fluid power motor starts to walk to travel, it is oily altogether to closed fhdraulic system to control brushless motor drive main oil pump simultaneously, through controlling three-position valve, direction valve respectively, reaching fluid power motor, drive the two ends rear wheel and realize the moving velocity and the reversing of this car, turn to, kill car and braking.(design-calculated major advantage of the present invention is that staring torque is big, the fast stepless change of starting to walk, the moment staring torque and conserve energy of protection brushless motor.)
Actuating device fluid power motor of the present invention directly is fixed on two rear wheels, and the holder of connection at both ends is dragged on the back axle of arm pattern, thereby connects into as a wholely with back axle, can be referred to as the driving rear axle that the arm pattern is dragged in novel holder.Simplified the drive configuration of car load, improved driving efficiency and saved energy (because the pressure oil that front and back wheel shock absorber (oil pump) up-and-down movement produces, the pressure oil that produces during the fluid power motor brake provides the energy of car load power demand about 2/5).
Vehicle body of the present invention is little, the chassis is low, the wide X height of long X is: the 2300X1080X1390 millimeter, axletree is apart from being: 1650 millimeters, complete vehicle weight is light: contain only 460 kilograms of load carrying abilities (3 people), hundred kilometers consumption of currents: below 2 degree, the maintenance cost of 1 year battery is about 300 yuan, and car load batch manufacturing cost is greatly about 6000-7000 unit.Therefore compare with existing any electronlmobil, manufacturing cost, use cost are all very low.Its suitable family of three is gone to work, goes to school and the retired personnel travels every day in 50 kilometers, is a kind of safety and comfort, the economical and practical vehicle.
The present invention and existing electric motor car with two wheels, three-wheeled electric vehicle is compared has safe, comfortable, practical advantage: (1) safety: because this chassis design gravity is low, complete vehicle weight is light, and speed is not easy to turn on one's side slowly, also is not easy to hurt human body because shell is arranged just in case bump; (2) comfortable: the present invention is designed to totally-enclosed the same with car, overcast and rainy pouring not, the sun is shining not, winter, cold wind can't blow, and disposed the backrest seat stearing and controlled by bearing circle, and stepless change travels, operation is driven the same with car, and comfortable safety has also increased the enjoyment of taking and driving; (3) practicality: it is simple that the present invention has a drive configuration, low-carbon energy-saving driving efficiency height, and the productive costs use cost is all very low, and it is simple to take the safety and comfort driver behavior, is the desirable miniature hydraulic three-wheeled automobile of a kind of economical and practical novelty.
