Embodiment 1

[0041] to attach figure 1 It is a schematic diagram of the application embodiment, combined with the attached figure 2 , 3 , a driving motor with a differential output function of the present invention is described in detail as follows:

[0042] The casing 1 of the driving motor casing is a motor fixing part, the differential is installed inside the stator, and the stator 12 and the stator wire group 13 are fixed inside the casing 1 of the driving motor casing, and the motor rotor 14 is fixed to the differential casing 16 Together; the output rotation of the motor rotor 14 is first output to the housing 16 of the differential, and the power is output through the first output half shaft 9 and the second output half shaft 10, when the first output half shaft 9 and the second output half shaft When the loads at both ends of the shaft 10 are the same, the differential planetary gear 17 and the planetary carrier 18 are stationary relative to the differential case 16, and when the ...

Embodiment 2

[0047] Such as Figure 4 As shown, the working process and working principle of the present embodiment are the same as those of the above-mentioned embodiment 1. What is different from the embodiment 1 is that the differential is installed at one end of the drive motor, and is installed on the outside of the rotor 14 through bolts. The first output half shaft 9 protrudes through the space inside the rotor 14.

Abstract

The invention relates to a driving motor with a function of differential speed output, which consists of a driving motor shell, a water cooling system, a differential speed output power system and a differential speed measuring device. The driving motor can be used in the field of special transport vehicle driving or in the field of engineering application needing two-end differential speed output. The driving motor adopts the differential speed output power system which is positioned inside the motor, outputs the differential speed from two axial ends of the motor and achieves the differential speed output of the two output ends according to load demands. The driving motor has the advantages of achieving the differential speed output in two directions by using one motor, saving space and simplifying a driving system. The lubrication of a differential mechanism adopts wet type lubrication, and the differential mechanism is separated from a rotor chamber of the driving motor. By adopting the water cooling system which has high efficiency, high reliability and low environmental requirements, the driving motor can adapt to severe environments with high temperature, high humidity and the like.

Description

technical field [0001] The invention relates to a driving motor, in particular to a driving motor with a differential output function. Background technique [0002] At present, motor drive technology has been widely used in vehicle or equipment drive, showing the advantages of high operating efficiency and low maintenance cost. During the operation of the vehicle, the road adhesion conditions encountered by each wheel may be different. At the same time, the output speed and torque of each wheel are different under the conditions of steering and slope. For the mechanical transmission system, the differential function can be It is realized through a mechanical differential. For electric drive, especially in the form of hub motor drive, the differential speed output can only be realized by controlling the two motors. The control accuracy of the differential speed depends on the detection of conditions such as the wheel speed. Increased the complexity of the control system. In...
