High Speed Metal Die Casting Hybrid Gearbox Housing For Flexible Driving

First, the main functions of the traditional Transmission with the engine as the power source

The Gearbox is the power transmission device of the car, which is composed of rows of gears of different sizes. The gear of the gearbox, that is, the transmission ratio, refers to the proportional relationship between the speed of the input shaft and the speed of the output shaft of the gearbox, that is, the output speed = the input speed/speed ratio. According to the power conversion principle, the torque transmission relationship can be expressed as: output torque = input torque × speed ratio × efficiency, because the efficiency of each gear is generally more than 90%, it can also be simply considered that the output torque under each gear and the input torque has a speed ratio multiplier amplification relationship. The Housing can be manufactured by CNC engraving, Sand Casting, transparent acrylic(PMMA/PC) 3D Printing.

The gearbox can expand the torque and speed of the driving wheel by changing the gear position. When the input speed and torque are unchanged, the higher the speed ratio, the smaller the output speed and the larger the torque; The smaller the speed ratio, the larger the output speed and the smaller the torque. When the vehicle is driving, the input end of the gearbox is connected to the engine, so that by selecting different transmission gears, the wheel end output characteristics of the engine can be changed, that is, the speed range can be changed and the wheel end torque capacity can be adjusted. The lower the gear, the greater the corresponding speed ratio, the lower the engine can work speed segment, and the greater the torque capacity of the driving wheel, the stronger the acceleration capacity; The higher the gear, the smaller the corresponding speed ratio, the higher the speed section of the engine can work, and the smaller the torque capacity of the driving wheel, the weaker the acceleration ability.
