Steering system for eccentric steering and three-wheeled motorcycle

Abstract

The invention discloses a steering system for eccentric steering and a three-wheeled motorcycle. The steering system is characterized in that a steering center line is a steering axis of a wheel, thesteering system is used for driving the wheel to steer, and a steering column seat is connected to the wheel and drives the wheel to steer. When the steering system is used, the rotating center of a steering driving system and the rotating center of the steering system are arranged to be of a non-concentric structure, the rotation driving axis is close to the front, the steering center line is positioned at the rear relatively and is located on a frame vertical pipe, the whole motorcycle can be arranged more compactly under the condition that the whole length of the whole motorcycle is the same, and the passenger carrying space can be improved; for the scheme in which the cargo carrying space is equivalent to the passenger carrying space, the shaft distance between the front wheel and therear wheel can be greatly shortened, and the strength and the stability are improved; and meanwhile, the rear steering system close to the rear part is relatively low and is relatively separated fromthe frame, so that the driving comfort is increased, the influence of vibration on steering driving can be reduced, the steering stability is kept, and the steering system is suitable for the structure for separating the steering driving system from the frame.

Description

technical field [0001] The invention relates to a vehicle steering mechanism, in particular to a steering system for eccentric steering and a three-wheeled motorcycle. Background technique [0002] Motorcycle is a kind of vehicle that is easy to use and low in energy consumption, and has good market demand; especially three-wheeled motorcycle, which has the function of carrying goods and people, has more demand in rural areas and suburbs. Based on the special structure and functions of the tricycle, it is necessary to have as large a riding or use space as possible, but its structure does not allow the desired length of cargo or passenger space. If the wheelbase is too long, the overall strength and driving stability of the motorcycle will be affected. Adverse effects, resulting in safety hazards. For motorcycles in the prior art, the general structure is that the steering drive directly drives the steering shaft and then acts on the wheels, and the steering center line ext...

Based on the special structure and functions of the tricycle, it is necessary to have as large a riding or use space as possible, but its structure does not allow the desired length of cargo or passenger space. If the wheelbase is too long, the overall strength and driving stability of the motorcycle will be affected. adverse effects, resulting in safety hazards

For motorcycles in the prior art, the general structure is that the steering drive directly drives the steering shaft and then acts on the wheels, and the steering center line extends downwards and forwards. This structure causes the wheels to move forward as a whole, increasing the length of the vehicle (front and rear axles distance), while the length of motorcycles (three-wheeled motorcycles) has standard requirements, and the driving steering and the longer length of the front wheels have a greater disadvantage to the passenger and cargo space of three-wheeled motorcycles. Influence, and in the existing structure, when there is enough seating and cargo space, the wheelbase is longer, and the body frame is also longer (longitudinal length), which affects the overall strength, stability and driving of the vehicle. Safety; Chinese patent 201310151897.3 discloses a steering structure. The steering structure consists of a handle tube steering column and a front fork steering column and is divided into two rotation axes, one front and one rear. The position of the handle tube steering column is the same as that of the prior art. Located in the frame riser; the front fork steering column is located at a certain part of the frame on the rear side of the frame riser; this structure can ensure that the overall length of the vehicle body is reduced under the condition of the same loading space, but due to the setting of the front fork steering column , will reduce the loading space or cause interference to a certain extent, and affect driving comfort; the front fork steering column and the handlebar steering column of this structure are both installed on the frame, although the rearward movement of the front wheels can reduce the The length of the body is small, but the loading space of the vehicle has not changed; if the loading space of the vehicle body is increased, the frame riser needs to be moved forward to increase the length of the frame, thereby increasing the weight of the vehicle, and because the frame is longer, the vehicle Poor stability
