Embodiment Construction

[0021] The specific technology of this technical solution will be described in detail below in conjunction with the accompanying drawings. In the following description, since multiple motors and multiple speed change gears are involved, when combined with the accompanying drawings, further explanations will be made on the basis of the previous explanations of the accompanying drawings. Therefore, after reading the details of each accompanying drawing, When explaining, it needs to be understood in conjunction with the previous description. In addition, in the specification, the speed change gear refers to the meshing of multiple gears as a whole. express.

[0022] The technical scheme of the present invention is a relay-type multi-motor multi-speed ratio electric vehicle automatic transmission device, including a planetary carrier housing 17 connected with the planetary carrier, a differential planetary shaft 10, and a speed changer connected with the differential planetary sha...

Abstract

The invention discloses a relay type multi-motor multi-speed-ratio electric vehicle automatic transmission device and belongs to the field of electric vehicles. A differential planetary shaft is connected with a motor through a variable gear; a big gear is arranged on a planet carrier shell; a one-way clutch is arranged between the big gear and a differential mechanism; the big gear is connected with different motors through additional variable gears; different speed ratios are achieved among the motors and the variable gears connected with the motors; the motors are connected with current detection devices; and each motor and the corresponding current detection device are connected with a controller. The relay type multi-motor multi-speed-ratio electric vehicle automatic transmission device can prevent the situation that running of an electric vehicle with a single motor is affected due to failure of the single motor, reduce the power consumption of the electric vehicle, improve running flexibility of the electric vehicle, simplify operation of the electric vehicle and prolong the service life of a battery.

Description

technical field [0001] The invention relates to a speed change device, in particular to a relay type multi-motor multi-speed ratio electric vehicle automatic speed change device, which belongs to the field of electric vehicles. Background technique [0002] Most of the current electric vehicles are connected with a reducer and a differential on a motor, and then output from the differential to two semi-shafts, which are respectively connected with two wheels to run on the road. The driving power of the electric vehicle driving mechanism of this structure is limited to a certain extent. Whether it is no-load or loaded, the driving motor uses a single motor. Pulling a small car, the power consumption of a large motor is much greater than that of a small motor when it is no-load. As an electric car using a battery, the power consumption is equivalent to shortening the driving mileage. If the ideal mileage is not reached, there may be insufficient power of the electric vehicle,...
