Abstract

The invention discloses a double-input and double-output wheel-sided transmission assembly which comprises a transmission shell. Power input shafts, power output shafts and planetary mechanisms are symmetrically arranged on the left side and the right side of the transmission shell correspondingly; one ends of the two power output shafts externally extend out of the transmission shell for drivingleft wheels and right wheels correspondingly; the other ends of the two power output shafts are fixedly connected with planetary frames correspondingly; the power output shafts are provided with output shaft gears, low-gear teeth are fixed to the transmission shell, high-low-gear tooth seats are arranged between the output shaft gears and the low-gear teeth, and the high-low-gear tooth seats are fixedly connected with gear rings of the planetary mechanisms; the high-low-gear tooth seats are engaged with sliding sleeves, sun wheel input shafts are provided with sun wheel input gears, and sun wheels are engaged with planetary wheels; one ends of the two power input shafts externally extend out of the transmission shell for being connected with driving motors; and the power input shafts are provided with input shaft gears, and the input shaft gears are engaged with the sun wheel input gears through idle wheels. The double-input and double-output wheel-sided transmission assembly is high in efficiency and low in cost.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a double-input double-output wheel-side transmission assembly. Background technique [0002] With the worldwide energy crisis and increasingly severe environmental problems, people have accelerated the exploration of alternative petroleum resources. At present, some countries have proposed to ban the sale of fuel vehicles. The new energy industry has developed rapidly. In recent years, the traditional models of various OEMs proportion gradually decreased. In addition to the direct drive of the motor and the power system of the motor matching the transmission, the powertrain of the pure electric vehicle on the market is also gradually emerging. Wheel-side drive is considered to be an ideal choice for high-end battery vehicles in the future. According to whether the wheels are directly driven by electric motors, the wheel-side drive system is divided into two driving modes: direct dri...
