Miniature hydraulic three-wheeled automobile

Abstract

The invention discloses a miniature hydraulic three-wheeled automobile, comprising an automobile body, a steering gear, a lighting instrument operating device, a front wheel arm-swing type vibration absorber (an oil pump), a driving and braking control system, a chassis, a closed hydraulic system power accumulator, a back wheel vibration absorber (an oil pump) and a driving device. 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 [0001] The invention relates to automobiles, in particular to a miniature hydraulic three-wheeled automobile. Background technique [0002] As we all know, due to the increasing depletion of non-renewable energy such as coal and petroleum, and the continuous improvement of people's awareness of low-carbon economy and environmental protection, and the development of various carbon-free clean energy such as solar energy, wind energy, and geothermal energy in recent decades, and the development of various countries In the medium and long-term development plan of electric vehicles, it has become the general trend to gradually reduce and replace gasoline vehicles and diesel vehicles. [0003] At present, the production cost of ordinary electric vehicles is more than 20,000 yuan, the power of the selected motor is about 3 kilowatts, and the power consumption per 100 kilometers is more than 10 degrees. The annual maintenance cost of the batteries currently in use is...

Problems solved by technology

[0003] At present, the production cost of ordinary electric vehicles is more than 20,000 yuan, the power of the selected motor is about 3 kilowatts, and the power consumption per 100 kilometers is more than 10 degrees. The annual maintenance cost of the batteries currently in use is also quite high. The length is 3000 mm, the width is 1400 mm, and the height is 1450 mm. Most of the structure adopts the transmission form of the mid-mounted motor; And the installation is complicated and consumes part of the kinetic energy, the driving efficiency is low, the production cost and the use cost are relatively high
