The power requirements of vehicle driving and braking are efficiently met by the power input of different speed ratios of the double motors and the speed ratio of the two-gear transmission. Meanwhile, the double-intermediate-shaft two-gear transmission is short in axial size, stable in transmission and suitable for gear sleeve gear engagement.
SUMMERY OF THE UTILITY MODEL
The utility model discloses just based on above technical background, provide a two jackshaft derailleur transmission structures of electricelectric motor car bi-motor input. The structure combines the advantages of double-motor double-speed-ratio input and double-intermediate-shaft transmission, realizes the power splitting of the motor input power and the transmission of the transmission. The system has simple structure, short axial dimension and stable power transmission, and is suitable for gear sleeve gear engagement. The double speed ratio of the motor input is combined with the speed ratio of the two-gear transmission, so that the power requirements of vehicle driving and braking are met efficiently.
The utility model adopts the technical proposal that: a transmission structure of a pure electric vehicle double-motor input double-intermediate-shaft transmission comprises a first motor and a second motor which have the same power and are respectively connected with an input shaft of the transmission through two electromagnetic clutches Clc1, Clc2 and a transmission gear; the separation and combination of the electromagnetic clutch can control the separation and combination of the motor and the transmission.
Further, the input speed ratio of the first motor isi1The input speed ratio of the second motor isi2And is andi1≠i2。
further, the main shaft of the double-intermediate shaft transmission can float and adopt the use of a sliding sleeve for engaging gears.
The utility model discloses the beneficial effect who produces is: the utility model discloses well two motor double speed ratio input and the transmission structure that two jackshaft derailleurs combine have realized two intermediate speed changers and have synthesized the advantage of two kinds of structures in the application on two motor double speed ratio input schemes. The multi-speed ratio is realized, the requirements of vehicle driving and braking are met efficiently, and meanwhile, the gear engaging structure is simple and reliable and the success rate is high.
Drawings
FIG. 1 is a schematic diagram of the transmission of the present invention;
in the figure, 1 is a first motor, 2 is a second motor, 3 is a first intermediate shaft, 4 is a second intermediate shaft.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
The utility model belongs to two motor input double intermediate shaft derailleur transmission structures of electricelectric motor car, it mainly includes two motors 1 that the power is the same and motor two 2 as input power, and motor 1 and motor two 2 use different input speed ratio for two jackshafts (being first jackshaft 3 and second jackshaft 4) derailleur input main shaftsi1Andi2. The motor I1 and the motor II 2 are connected with the input shaft of the transmission through electromagnetic clutches Clc1 and Clc2 and a transmission gear. The double-intermediate shaft transmission is geared by using a sliding sleeve. The sliding sleeve can realize gear engaging operation under the control of the control mechanism.
When the vehicle drives, the two input motors carry out reasonable torque distribution and work independently or cooperatively. The double speed ratio of motor input combines the speed ratio of two jackshaft derailleurs, realizes a plurality of speed ratios, high-efficient drive vehicle. When the vehicle brakes, the double-intermediate-shaft transmission fixes a speed ratio, and the two motors distribute the braking energy through the double speed ratios and the torque, so that the braking energy recovery efficiency is maximized.
It should be noted that the above-mentioned embodiments are illustrative and not restrictive of the technical solutions of the present invention, and equivalents of those skilled in the art or other modifications made according to the prior art are intended to be included within the scope of the claims of the present invention as long as they do not exceed the spirit and scope of the technical solutions of the present invention.
