Description

Tricycle

Technical field

A kind of tricycle is the utility model is related to, belongs to tricycle technical field.

Background technology

At present, the development of the vehicles such as automobile make it that town road is especially crowded, and resulting vehicle exhaust It is a key factor of amblent air temperature change and global air temperature warming, delays smooth stifled guarantor, energy-saving and emission-reduction, builds good life cycle The target that border is present each metropolitan government and citizen pursue, thus environment-friendly high-efficiency safety and comfort fall three-wheeled electric vehicle also into For important R＆D direction.

The small winged center of existing tricycle engine or motor is typically in front of chain stay axis center, with biography Unite structure drive belt-driven vehicle when, due to rear damping stretching motion when belt can stretch or stretch therewith, when belt is stretched When contracting amount is insufficient, belt slippage can be caused or break situation, the service life of serious curtailment belt；Also have in addition directly by motor Be arranged on chain stay, though when avoiding damping campaign belt it is flexible, aggravated rear overhang weight, reduced vehicle comfort level.

The content of the invention

For above-mentioned weak point of the prior art, the utility model aims to provide a kind of tricycle, is not influenceing On the premise of vehicle comfortableness so that influence belt not by the stretching motion of rear shock absorber using the tricycle of belt transmission Service life, service life is long and stable and reliable operation.

To achieve these goals, the technical solution of the utility model：A kind of tricycle, after including two front-wheels, one Take turns and build the vehicle frame supervisor between two front-wheels, the trailing wheel, it is characterised in that：Vehicle frame supervisor middle part by bottom fork axis with Chain stay is connected between the trailing wheel central shaft, rear shock absorber is connected between the chain stay end and vehicle frame supervisor rear portion, Wherein, the bottom fork axis central axis is parallel with the trailing wheel central axis, and also include by belt drive it is described after The motor of wheel, the central axis of the central axis of the motor and the bottom fork axis coincide.

Further, vehicle frame supervisor include top be used for take support two first supervisors and bottom be used to riding Two second supervisors of support, wherein, the chain stay quantity is two, and it is connected to described in the trailing wheel central shaft both ends and two Between second supervisor, pass through the two chain stay axis connections, the driving respectively between two chain stays and two second supervisors Motor axial direction both ends are correspondingly positioned on two second supervisors, and the central axis of the motor is in two chain stays Coincided between axle and with the central axis of two bottom fork axis.

Further, two it is described second supervisor on be respectively welded be located it is corresponding with motor axial direction both ends Location-plate, it is detachably connected between the electric machine casing both ends of the motor and two location-plates.

Further, there is operation gap between the output gear of the location-plate and the motor.

The beneficial effects of the utility model：Structure is novel, by by the central axis of motor and bottom fork axis central shaft Line coincides, and ensures on the premise of vehicle comfortableness is not influenceed so that using the tricycle of belt transmission not by rear damping The stretching motion of device and influence the service life of belt, service life is long and stable and reliable operation.

Embodiment

The utility model is further described with reference to specific embodiment and accompanying drawing.

A kind of tricycle as shown in Figure 1 and Figure 2, it includes two front-wheels 10, a trailing wheel 11 and built in two front-wheel 10th, the vehicle frame supervisor 13 between trailing wheel 11, the middle part of vehicle frame supervisor 13 between bottom fork axis 17 and the central shaft of trailing wheel 11 by connecting There is chain stay 14, the end of chain stay 14 and vehicle frame supervisor are connected with rear shock absorber 15 between 13 rear portions, wherein, the central shaft of bottom fork axis 17 Line is parallel with the central axis of trailing wheel 11, and also includes the motor 16 that trailing wheel 11 is driven by belt 18, driving electricity The central axis of the central axis of machine 16 and bottom fork axis 17 coincides.

Specifically, two front-wheels 10, a trailing wheel 11 form level triangle structure.Vehicle frame supervisor 13 builds thereon, and Vehicle frame is responsible for 13 front ends with respect to activity orientation handle pipe 12, is used for controlling the direct of travel of tricycle and turning.

Vehicle frame supervisor 13 includes two first supervisors and bottom of the top for taking support and is used to ride the two second of support Supervisor, wherein, the quantity of chain stay 14 is two, and it is connected between the central shaft both ends of trailing wheel 11 and two second supervisors, and two is flat Two rear shock absorbers 15 of corresponding connection between fork 14 and two first supervisors, and pass through two respectively between two chain stays 14 and two second supervisors Bottom fork axis 17 is connected, and 16 axial both ends of motor are correspondingly positioned on two second supervisors, at the central axis of motor 16 Coincided between two bottom fork axis 17 and with the central axis of two bottom fork axis 17.

It is respectively welded on two second supervisors and the location-plate corresponding with 16 axial both ends of motor, motor is located It is detachably connected between 16 electric machine casing both ends and two location-plates, for example is connected using several bolt and nuts or screw etc., By being detachably connected in order to later maintenance and maintenance.Finally, have between the output gear of location-plate and motor 16 There is operation gap, interference is driven to the belt of trailing wheel 11 to avoid influenceing motor 16.

The technical scheme provided above the utility model embodiment is described in detail, used herein specifically Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model Example, the there will be changes in embodiment and application, in summary, this specification content should not be construed as To limitation of the present utility model.
