Sitting type motor tricycle provided with pedals

Abstract

The invention discloses a sitting type motor tricycle provided with pedals, comprising a vehicle frame, wherein the vehicle frame consists of a four-beam keel and a flat frame assembly, a rear compartment is arranged at the top of the rear side of the vehicle frame, the bottom of the rear side of the vehicle frame is connected with a rear axle assembly through a plate spring damping mechanism, a rear wheel is arranged at each of the left end and the right end of the rear axle assembly, an air inlet pipeline is arranged on the vehicle frame, and is used for an air cooling power device, a braking system is arranged on the vehicle frame, and is used to brake the rear wheels, a self-unloading device is between the flat frame assembly and the rear compartment, a dual-purpose structure used as both a backrest and a passenger seat is arranged, an electromechanical dual-purpose power device is adopted, and a front wheel is improved as a self-walking structure. The sitting type motor tricycle provided with the pedals disclosed by the invention has the advantages of firmness and durability, large loading capacity, more uniform distribution of loading capacity, good braking effect, comfort and safety for controlling a hand brake, saved labor force for the self-unloading, enhanced function of the backrest and improved safety and comfort as a front-fixed and back-movable plate spring damping structure is arranged, and has the functions of saving energy, protecting the environment, reducing emission and realizing continuous long-distance driving.

Description

technical field [0001] The invention relates to a tricycle, in particular to a pedal-type tricycle. Background technique [0002] In recent years, motorcycle tricycles have become one of the commonly used means of transportation for people or goods. However, the existing motorcycles on the market have the following defects or deficiencies: [0003] 1. Generally, two keels are used, which have low strength, poor load-bearing capacity and uneven force; The keel also has a great influence on the installation strength of the front bumper, and the safety is not high; [0004] 2. The braking system of the rear wheel of a motorcycle tricycle is more complicated and the manufacturing cost is high, and many tricycles do not have a handbrake device. For a motorcycle tricycle with a handbrake device, the handbrake lever is set at the pedal. When using the handbrake, the driver needs to bend over. operation, which will cause a greater safety hazard; [0005] 3. Since the tricycle ne...

AI Technical Summary

Problems solved by technology

[0003] 1. Generally, two keels are used, which have low strength, poor load-bearing capacity, and uneven force; the keel is welded in sections, and there are many solder joints, which not only affects the appearance, but also is easy to break, and the anti-rollover performance is poor; two keels The keel also has a great influence on the installation strength of the front bumper, and the safety is not high;

[0004] 2. The brake system of the rear wheel of a motorcycle tricycle is relatively complicated, and the manufacturing cost is relatively high, and many tricycles do not have a handbrake device. For a motorcycle tricycle with a handbrake device, the handbrake lever is set at the foot pedal. When using the handbrake, the driver needs to bend over operation, which will cause a greater safety hazard;

[0005] 3. Since the tricycle needs to be loaded, manual operation is required for loading and unloading, which consumes a lot of time and physical strength

Especially for materials such as sand, gravel, grain, soil, etc., if there is no self-unloading device, it will be very troublesome

At present, the rear compartments of many motorcycle tricycles are generally fixed on the frame and cannot be unloaded;

[0006] 4. The backrest on the rear side of the driver's seat is fixed. When people need to be carried, there is no seat in the rear compartment. People sitting in the rear compartment should move a bench or sit directly on the side rail of the rear compartment. Occupants can be very dangerous during emergency braking

At present, the lugs at both ends of the leaf spring are connected to the lifting lugs at the bottom of the frame through a swing rod. When the wheel passes through a bumpy road in this connection structure, the leaf spring will swing back and forth, and the bearing capacity is small. The impact force will cause damage to the swing rod, resulting in a car accident and poor safety

In addition, the bushes inside the lugs at both ends of the leaf spring are often damaged by impact;

[0008] 6. The general power devices of existing motorcycle tricycles generally use gasoline engines, and there is no combination of engines and batteries as the power of motorcycle tricycles; using batteries can be more economical and less polluting. When the battery is undervoltage, it can be powered by the engine Driving and charging the battery

[0009] 7. The gasoline engine runs for a long time and generates a lot of heat. There is no radiator on the general motorcycle tricycle, which will seriously affect the service life of the engine over time;

[0010] 8. The existing general motorcycle tricycles are generally riding style, and the driver will be very tired after a long time riding on the driver's seat
