Pedal seat three-wheeled motorcycle

Abstract

Pedal seated three-wheeled motorcycle, including a frame composed of four-beam keel and flat frame assembly, a rear compartment is provided on the top of the rear side of the frame, and a rear axle assembly is connected to the bottom of the rear side of the frame through a leaf spring shock absorbing mechanism. The left and right ends of the rear axle assembly are respectively provided with a rear wheel, the frame is provided with an air intake duct for the air-cooled power unit, and the frame is provided with a brake system for braking the rear wheels; the flat frame assembly and the rear compartment There is a self-unloading device between them, and a dual-purpose structure for the backrest and passenger seat, a dual-purpose power device for electromechanical, and an improved self-propelled structure for the front wheels. The invention is strong and durable, has a large load capacity, and has a more uniform load distribution; good braking effect, comfortable and safe control of the handbrake, self-unloading saves manpower, and enhances the function of the backrest; It ensures safety and comfort; it has the functions of energy saving, environmental protection, emission reduction, and continuous long-distance driving.

Description

technical field [0001] The invention relates to a tricycle, in particular to a pedal-riding three-wheel motorcycle. Background technique [0002] In recent years, motorcycle tricycles have become one of the most commonly used means of transportation for carrying people or cargo. But existing motorcycle on the market has following defect or deficiency: [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 tricyc...

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
