Abstract
The utility model discloses a power transition connection structure of an all-electric vehicle which is characterized in that an annular flat plate is arranged; the annular flat plate is connected with the end surface of a motor by a through hole on the inner periphery of the annular flat plate, and connected with the end surface of a speed changer by a through hole on the outer periphery thereof; the output shaft of the motor passes through the hollow area of the annular flat plate, extends toward the side where the speed changer is positioned, and is concentric with the speed changer. The power transition connection structure adopts the flat type connecting piece, thus not only leading the motor and the multi-gear speed changer to be directly butted, but also leaving enough space for normal releasing and engaging of a clutch, and leading to compact and effective whole structure.
Description
Technical field
The utility model relates to the transition connection structure between motor in electric automobile and the change-speed box, is used for being connected between motor and multi-shifting speed variator.
Background technology
At present, the following miniature electric automobile of storage battery car and 500kg all adopts by motor direct-drive, and change-speed box is not set, and is this simple and practical, but can only be used on the less electronlmobil of quality.And on the bigger pure electric sedan of quality, what generally adopt is automatic transmission with hydraulic torque converter, and automatic transmission with hydraulic torque converter makes integral vehicle cost higher; Other has the fixed drive ratio of employing pattern, connects by spline, and this mode can solve electronlmobil needed high pulling torque problem when starting to walk and climbing brokenly, but it is difficult to satisfy the travel requirement of pure electric automobile under various operating mode.If adopt the speed change pattern of many retainings, again because of the constructional feature of motor itself, be difficult to accomplish that it not only directly docks with multi-speed gear box, and stay enough normal separation and combination of space assurance power-transfer clutch.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of pure electric automobile power transition connection structure is provided, so that realize motor is directly docked with multi-speed gear box, and can also stay enough normal separation and combination of space assurance power-transfer clutch.
The utility model technical solution problem adopts following technical scheme:
The characteristics of the utility model pure electric automobile power transition connection structure are that ring plate is set, described ring plate is connected with the end face of motor with its inner circumference through hole, and be connected with the end face of change-speed box with its neighboring through hole, the output shaft of motor stretches to change-speed box place one side by the hollow region of described ring plate, and remains concentric with change-speed box.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model adopts flat attaching parts, and motor is directly docked with multi-speed gear box, has guaranteed that power-transfer clutch is normal and separates and combination but also leave enough spaces, compact overall structure and effectively.
2, the utility model is simple in structure, cost is low, on pure electronic vapour different motors is connected to become concentric integral body with different change-speed boxs, and the dimensional parameters that changes ring plate is promptly applicable to different vehicles.
3, after the utility model can guarantee motor and change-speed box is connected higher concentricity is arranged, motor effectively reduces the noise of running part with respect to the beating of change-speed box in the time of can reducing vehicle ' with this.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model ring plate structural representation.
Number in the figure: 1 ring plate, 1a inside circumference through hole, 1b neighboring through hole, 1c hollow region, 2 motors, 3 change-speed boxs, 4 power-transfer clutchs, 5 flanges.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, Fig. 2, present embodiment is provided with ring plate 1, ring plate 1 is connected by the end face of bolt with motor 2 with its inner circumference through hole 1a, and be connected by the end face of bolt with change-speed box 3 with its neighboring through hole 1b, the output shaft of motor 2 stretches to change-speed box 3 by the hollow region 1c of ring plate 1.
In concrete the enforcement, the output axle head of motor is connected with flange 5, flange 5 and power-transfer clutch 4 and is connected by bolt, and power-transfer clutch 4 is connected by the input end of spline and change-speed box 3.In this version, the output shaft of motor and the input shaft of change-speed box can keep higher concentricity.The rotation of motor drives power-transfer clutch 4 by flange 5, and then drives the input shaft rotation of change-speed box 3, and powered vehicle is advanced thus.
Claims (1)
