Abstract

The utility model relates to a motor tricycle driven by a single rear wheel. The motor tricycle changes the upward bending position of the direction shaft of a seat type motorcycle into a forward stretching position, the shaft center of the direction shaft is perpendicular to the ground to form movable connection with the chassis of a carriage through a direction shaft position pin, so that the direction shaft can rotate within the range of 90 DEG in a plane parallel to the ground, and the running speed is controlled by a gasoline throttle. When a direction handhold is pushed to the right or to the left by hands, the direction handhold drives the carriage and two front wheels to make motion to control the running direction. The utility model provides families, women, older adults and individual peddlers with a motor tricycle with the advantages of simply driving, convenience and safety.

Description

Back single wheel drives motor tricycle

Back single wheel drives the technical field that motor tricycle belongs to motor bike, and particularly suitable women, old man's short-distance and medium-distance convey goods.

According to the knowledge of the applicant, the motor bike of being sold in the market, two-wheel can only as ride instead of walk, amusement, motion, sports with, as the railway carriage of the motor-tricycle that conveys goods generally all in the back, convey goods in the chaufeur back, always worry the motor bike of loss of goods, stolen and women, this complexity of old man's difficult handling.Learn according to the applicant, end that it is known public for society still not have technical scheme identical with the application or product by the applying date.There is not same utility model to propose to apply for and announced to Patent Office by other people yet.Do not find identical therewith patent documentation by literature search yet.

The design the purpose of this utility model is: for family, women, old man, individual traders and pedlars provide a kind of drivings simple, safe, motor tricycle easily.

The utility model technical scheme required for protection is as follows: it is that the motor scooter of selling on the market is done following improvement---(1) is the preceding axis of orientation of motor scooter K/UP; change into and stretch suitable length forward, the axial line vertical ground of axis of orientation position seat.(2) quality of the weight in the seat formula motor self-acting clutch is increased by 20～30%.(3) motorcycle direction handle is fixed on the railway carriage.Make railway carriage, two front-wheels with steering handle rotate grasps travel direction, left brake lever is controlled travelling and braking of two front-wheels by two backguys, former service brake is still controlled trailing wheel, right twist grip throttle control control engine throttle, thereby control moving velocity.

(4) install in the railway carriage front two headlights, open or close by former car circuit control.

(5) circuit of former seat formula car, service brake, back shock absorption device etc. do not change.

With reference to the accompanying drawings in conjunction with the embodiments, the technical program is described further:

Fig. 1 be after wheel drive motor tricycle front view only;

Fig. 2 is the frame chassis front elevation.

1---positive three-wheel vehicle rear portion vehicle frame, promptly former motor scooter frame; 2---driving device, the power of driving engine output passes on the trailing wheel by driving device; 3---connect thick stick, be fixed on vehicle frame before, be movably connected with the railway carriage chassis; 4---front-wheel, about each-individual, axial line overlaps, perpendicular to working direction, but mutually noninterfere campaign plays support railway carriage and veer effect; 5---railway carriage, on the chassis, lade; 6---the steering handle assembly, be fixed on the railway carriage, steering handle rotates, and drives railway carriage and rotates, and grasps travel direction, and is right the control throttle, and left brake lever is by two backguys, and transhipment is changeed before the control two; 7---axis of orientation position seat, be fixed on the connection thick stick, direction of passage axial position pin and vehicle frame are movably connected; 8---extension spring, connect about thick stick each one, an end hook is on the chassis, and an end hook makes to turn to return connecting on the thick stick; 9---the direction axial position pin connects vehicle frame and axis of orientation position seat; 10---the railway carriage chassis comprises before two front-wheels of shock absorption device being movably connected with steering shaft position seat; 11---headlight, use as night light; 12---positioning plate, the restriction chassis turns to certain angle.

Back single wheel motor tricycle method of operation is as follows: start the engine, and open the throttle wide, trailing wheel promotes car load to overtake, two hold steering handle, push away then car left-handed turning to the right, on the contrary right-hand turning, shift onto the seat just before then to overtake, throttle is the control speed of a motor vehicle, during brake, revolve little throttle, the right threading service brake, left hand pinch left side brake, the car position of stopping.

The utility model is compared what have beneficial effect with background technology be to be family, women, old man and individuality The retailer provides simple, convenient, the safe motorcycle of driving of a kind of suitable family expenses, short-distance transportation.
