Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the practical application of the utility model embodiment
Fig. 2 is the structural representation (cutaway view) of the utility model embodiment;
Fig. 3 is the structural representation of motor among the utility model embodiment;
Fig. 4 is support bracket fastened structural representation among the utility model embodiment;
Wherein: 1-five-way pipe, 2-motor, 3-motor connection pipe, 4-fixed support, 41-mounting hole, the 42-connecting bore, 43-latch, 5-jam nut, 6-chain wheel, 7-chain guard, the 8-front fork, 9-needle bearing, 10-thrust ball bearing with flat seat, 11-hold-down nut, 12-bicycle middle shaft.
The specific embodiment
As shown in Figure 1 and Figure 2, this mid-motor of portable that is installed on the ordinary bicycle that present embodiment provides comprises five-way pipe 1, the motor 2 along the left and right directions horizontal arrangement and is connected in fixed support 4 between five-way pipe and the motor.
In the present embodiment, the motor housing of motor 2 is provided with a motor connection pipe 3 that penetrates in the described five-way pipe 1, and be shaped on outside thread on this motor connection pipe 3, one end (right-hand member) of motor connection pipe 3 and motor housing are connected as a single entity and are against the right-hand member of five-way pipe 1, and it is outer and be positioned at the left side of five-way pipe 1 that the other end (left end) stretches out five-way pipe 1.
Bicycle middle shaft 12 is assemblied in the motor connection pipe 3 by needle bearing 9, and is arranged with on the bicycle middle shaft 12 by hold-down nut 11 and presses the thrust ball bearing with flat seat 10 that is fixed on described needle bearing 9 one sides.If we select general plain bearing for use, because the restriction of five-way pipe, we can only select very thin thin-walled deep groove ball bearing, but bicyclist's the power of stepping on is bigger, so bearing is easy to damage, needle bearing just can't axial location painstakingly preferably if select.This example utilizes needle bearing and thrust ball bearing with flat seat way of combining well to solve above problem.
As shown in Figure 3, described fixed support 4 is close to five-way pipe 1 left side and is arranged and be shaped on it mounting hole 41 that is enclosed within outside the motor connection pipe 3, is threaded on the described motor connection pipe 3 fixed support 4 is pressed two jam nuts 5 that are fixed on five-way pipe 1 left side.Also be shaped on two connecting bores 42 on the fixed support 4, fixed support 4 is captiveed joint with motor housing by described connecting bore 42 usefulness screws.
And present embodiment also is shaped on a plurality of latches 43 along the circumferential direction spaced apart in the right ports of mounting hole 42 along the place.
The installation method of the mid-motor of present embodiment is as follows:
1, chain wheel 6, chain guard 7 are fixed on the swivel behind the motor double reduction by screw.
2, the motor connection pipe 3 with motor 2 inserts in the five-way pipe 1 of bicycle from right to left, and the left end portion of motor connection pipe 3 is stretched out five-way pipe 1 outside.
3, the one side that fixed support 4 is had latch 43 is towards five-way pipe 1, screw penetrated connecting bore 42 on the fixed support 4, thereby fixed support 4 is locked on the motor housing.
4, motor firmly is pressed on the bicycle front fork 8, nut with a jam nut 5(M33) is tightened on the motor connection pipe 3, the latch 43 of compressing on the fixed support 4 eaten in the entity of five-way pipe 1 into (thereby can avoid fixed support to rotate), and motor just firmly is fixed on the vehicle frame and can rocked like this.
5, with the nut of another jam nut 5(M33) also be tightened on the motor connection pipe 3, further strengthen Joint strenght and the stability of motor.
Certainly, above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow people can understand content of the present utility model and implements according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spiritual essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
