Problems solved by technology

[0004] In view of the fact that the existing electric vehicle has only one motor, under the condition of small load, the electric vehicle consumes a lot of power, and under the condition of large load, the maximum load capacity is limited, especially on slopes or mountain roads, the power will be insufficient. The invention provides a multi-motor electric vehicle with staggered motors, the purpose of which is to reduce the power consumption of the electric vehicle when the load is small, improve the traction force of the electric vehicle on slopes or mountain roads, meet the demand for electric vehicles in the vast rural market, and expand Market Share of Electric Vehicles

Embodiment 1

[0024] figure 1 It is a structural schematic diagram of the driven transmission gear fixed on the differential planet carrier housing. The rear axle of the electric vehicle is provided with a differential gear 10, and the left and right driven transmission gears 14 are fixed on the planetary carrier housing 13 of the differential gear, and the power of the motor unit is transmitted to the left and right transmission driven gears respectively through the transmission. On the speed change gear 14, the left and right two driven speed change gears 14 are transmitting power to the planet carrier housing 13, and the differential drives the left and right half shafts 11 to rotate.

Embodiment 2

[0026] figure 2 It is a schematic diagram of the structure of a driven transmission gear fixed on the differential planet carrier housing. The rear axle of the electric vehicle is provided with a differential 10, and the differential 10 is arranged between multiple groups of motors. Among the multiple groups of motors, at least The two groups of motors are output to the differential 10 through the driven transmission gears connected to the planet carrier housing 13 of the differential 10 , the output of the differential 10 is output to the half shaft 11 , and other motor groups are indirectly connected to the half shaft 11 .

[0027] In this embodiment, the left and right two motor groups concentrate power on the driven speed change gear 14 through the speed changer, and the driven speed change gear 14 on the right side is connected with figure 1 Also fixedly connected on the planetary carrier housing 13 of the differential, the driven transmission gear 14 on the left side ut...

Embodiment 3

[0029] image 3 It is a schematic diagram of the structure of the driven transmission gears arranged on the axle shafts at both ends of the differential. A differential 10 is provided on the rear axle of the electric vehicle, and the differential 10 is arranged between multiple sets of motors. The output end of the differential 10 A half shaft 11 is connected to the top, and the left and right half shafts 11 are connected with a driven speed change gear 14 through a reverse locking one-way clutch. In this embodiment, the left and right half shafts 11 are respectively provided with a reverse locking one-way clutch. One 21a and reverse locking one-way clutch two 21b, each driven transmission gear is indirectly connected with a group of motors, in the present embodiment, its group of motors is motor one 15a and motor two 15b through speed changer, utilizes reverse lock Only one-way clutch one 21a is connected on the right half-shaft, and another group of motors is that motor is t...

Abstract

The invention provides a multi-motor electric vehicle with motors arranged in a staggered manner and belongs to the field of electric vehicles. Multiple groups of motors are arranged on a rear axle of the electric vehicle, each group of motors comprise two non-coaxial motors arranged oppositely, output shafts of each group of motors are indirectly connected to one variable gear, the variable gears are connected to a planet carrier casing of a differential or indirectly connected to a half shaft, the traction force of the vehicle can be improved by means of a plurality of motors arranged on the rear axle of the electric vehicle, motors or combined motors with different power are used according to load of the vehicle, the power consumption of the electric vehicle can be reduced, and the flexibility of drive power of the electric vehicle is improved.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a multi-motor electric vehicle with interleaved motors, which belongs to the electric vehicle [0002] Motor vehicle field. Background technique [0003] Most of the electric vehicles currently on the market are connected to a motor with a reducer and a differential in succession, and then the differential transmits the power to the two half shafts, and the two half shafts are respectively connected to two wheels on the road. drive. The driving power of the electric vehicle driving mechanism with this structure adopts a larger motor, no matter it is a small load or a large load, because the driving motor uses one motor, it is equivalent to a large horse-drawn car at a small load, and the power consumption of a large motor It consumes much more power than using a small motor at no-load. As an electric vehicle using a battery, the power consumption is equivalent to shortening the driving mi...
