Abstract

The invention discloses a coaxial electric drive axle with a differential lock, which enables a motor to transmit power of the motor to a differential mechanism through a planetary reducer and transmit the power to wheels on two sides. The drive axle is characterized in that the drive axle motor is fixed with a sun gear of the planetary reducer through a spline, power is transmitted to the planetary reducer and then transmitted to the differential mechanism, and the differential mechanism outputs the power to wheels at the two ends through half shafts; a differential lock and a planet carrier are both provided with end face teeth, the differential lock is inserted into a half axle wheel carrier, when a vehicle runs normally, an electromagnetic controller attracts the differential lock to be recovered, and the differential lock is separated from the end face teeth of the planet carrier; when a vehicle slips, the differential lock end face teeth are combined with the planet carrier end face teeth, the planet carrier and the differential lock are fixed into a whole, then the planet carrier and the half axle wheel carrier are combined into a whole, the differential mechanism is locked, and power is evenly output to the two sides.

Description

technical field [0001] The invention relates to the technical field of pure electric light trucks, in particular to a coaxial electric drive axle with a differential lock. Background technique [0002] In traditional pure electric light trucks, the motor transmits the power to the drive axle through the transmission shaft. The car's escape ability. Contents of the invention [0003] In order to solve the above problems, the present invention provides a coaxial electric drive axle with a differential lock. [0004] The technical solution provided by the present invention is: a coaxial electric drive axle with a differential lock, including a motor, which is special in that the motor is fixed to the axle housing; the motor is connected to the The sun gear, the sun gear is meshed with the planetary reducer, and the power is transmitted to the differential through the planet carrier of the planetary reducer, and the planetary reducer and the differential are contained in the...
