Problems solved by technology

Since the motor is completely enclosed in the hub and is in a sealed state, the heat dissipation of the motor is not good during use, which affects the efficiency of the motor; at the same time, due to the space limitation inside the hub, the motor in the hub is generally small, and there is no noise generated by the motor. The power is directly transmitted to the wheel rim through the end cover, resulting in poor overall power of the electric vehicle, and a more obvious lack of power when climbing a slope

Embodiment 1

[0035] Embodiment 1: A side drive device for an electric vehicle

[0036] Such as figure 1 with figure 2 As shown, a side drive device for an electric vehicle includes a substantially L-shaped fork body 1, and the fork body 1 gradually increases from the front end to the rear end. The front end of the fork body 1 is horizontally provided with a connecting hole 11 for being rotationally connected with the vehicle frame and the rear fork 6 matched therewith. There are three reinforcing strips 111 (such as Figure 4 shown). The setting of the reinforcing bar 111 can enhance the structural strength of the connection hole 11 at this place.

[0037] The fork body 1 gradually protrudes from the middle to its inner and outer sides. Such as image 3 As shown, the middle and rear part of the fork body 1 is provided with a motor chamber 17, the motor chamber 17 is recessed inside the fork body 1, the opening of the motor chamber 17 faces the outside of the fork body 1, and the ope...

Embodiment 2

[0042] Embodiment 2: A side drive device for an electric vehicle

[0043] Such as Figure 5 with Image 6 As shown, the difference between the second embodiment and the first embodiment is that the inner surface of the front part of the fork body 1 of the second embodiment is provided with a plurality of intersecting reinforcing ribs 20, and the reinforcing ribs 20 are connected with the flanges 16 at the upper and lower ends of the front part of the fork body 1. The integrated body is used to strengthen the strength of the front end of the fork body 1, so that the structural strength of the fork body 1 is higher, and it is more suitable for the requirements of heavy load and bumpy road surface. The inner side of the front part of the fork body 1 is also provided with a protruding post 13, and the end of the protruding post 13 is provided with a threaded hole. 1 connected as one. At the same time, interlaced reinforcing ribs 20 are arranged in the motor chamber 17 to streng...

Embodiment 3

[0044] Embodiment 3: A side-mounted electric vehicle with a driving device

[0045] Such as Figure 7 As shown, a drive device side-mounted electric vehicle includes a vehicle frame 8, and one side of the rear end of the vehicle frame 8 is provided with the electric vehicle side drive device in Embodiment 1; the other side of the vehicle frame 8 rear end is installed with the The back fork 66 (such as Image 6 shown). The shape of the rear fork 66 is similar to the fork body 11, and the other end of the wheel shaft 3 is rotatably connected on the rear fork 6, and the rear wheel 7 of the electric vehicle is installed in the middle part of the wheel shaft 3. A shock absorber is connected in the shock absorber groove 14 of the fork body 11 , and the other end of the shock absorber is connected with the vehicle frame 8 . Between fork body 1 and the connecting hole 11 of rear fork 6 front ends, be provided with connecting shaft, half of connecting shaft is in the connecting hole...

Abstract

The invention discloses an electric bicycle with a laterally-arranged driving device, and the laterally-arranged driving device thereof. The laterally-arranged driving device of the electric bicycle comprises a fork, a motor is arranged behind the outer side of the fork, a gear cavity is integrally formed in the inner side of the fork, and an output shaft of the motor extends into the gear cavity; and a reduction gear set and an axle are arranged in the gear cavity, power generated by the motor is transmitted to the axle through the reduction gear set, and a cover for fixing the gear set and the axle is arranged at an opening of the gear cavity. The laterally-arranged driving device of the electric bicycle can output large torque for the electric bicycle.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a side-mounted electric vehicle with a driving device and a side-mounted driving device thereof. Background technique [0002] Electric vehicles are generally two-wheeled vehicles driven by electricity and are widely used for short-distance travel in the city. Existing electric vehicles are generally rear-wheel driven, and the drive motor is entirely sealed in the hub of the rear wheel. The driving motor generally adopts a permanent magnet motor, in which a coil is wound on the stator, and a fixed shaft protrudes from both ends of the stator, and the fixed shaft is fixed on the rear fork of the frame. The two ends of the rim are closed on the shaft, and a plurality of magnetic pieces are uniformly distributed on the inner side of the rim to form a rotor. When the wheel hub is working, the coil on the stator is energized to generate a magnetic field, which tends to make the magnetic sheet ...
