Bending steering four-wheel motorcycle

Abstract

The invention provides a waist-steering four-wheeled motorcycle, which is composed of a tractor and a carriage, and is hinged to each other through an upper node and a lower node of a steering knuckle. The head of the carriage is a high-strength and impact-resistant truss-type trapezoidal three-dimensional space structure. The upper part is equipped with a steering shaft, steering wheel, and bevel gears; the lower part is equipped with clutches, brakes and accelerator pedals. The bevel rack is mounted on the towing head as a cantilever and meshes with the bevel gear. The driver applies steering torque to the steering wheel, and through the steering shaft, the bevel gear drives the bevel rack to swing to realize bending steering. The tractor is equipped with an engine assembly and turns the front wheels through a drive shaft. Therefore, it provides a short-distance transportation tool with less fuel consumption, less pollution, less road occupation, less cost, low tank compartment, and light for short-distance transport of small batches of goods and passengers scattered in urban and rural areas, rural fairs, and tourism and entertainment. It is an ideal means of transportation for the old, weak, sick and disabled. You can enter families and farmers to pick up two-wheeler and tricycle shifts. It is an ideal model for developing half-electric and half-oil hybrid vehicles.

Description

(1) Technical field [0001] The invention relates to a motorcycle, in particular to a bent-over steering four-wheel motorcycle. (2) Background technology [0002] A kind of known front-wheel steering rear-wheel drive four-wheel motorcycle steering system comprises: steering wheel, steering shaft, steering universal joint, steering drive shaft, steering gear, steering rocker arm, steering straight rod, steering knuckle arm, left steering Knuckle, left steering knuckle kingpin, left steering trapezoidal arm, steering tie rod, right steering trapezoidal arm right steering knuckle, right steering knuckle kingpin, etc. In order to make the steering wheel have steering portability, accuracy and driving stability, a difficult front wheel alignment system must be designed on the steering wheel, that is, the front wheel camber, kingpin inclination, kingpin caster, front toe-in . Thus it can be seen that the structure of the front wheel steering system is quite complicated, the proce...

Problems solved by technology

In addition, the rear wheel drive must adopt an integral rear wheel drive axle and its transmission device including the final drive, differential, and half shaft, resulting in a smaller ground clearance and increased unsprung mass

The ride comfort and riding comfort deteriorate, the floor height of the compartment increases, the center of gravity of the vehicle increases, the roll stability angle decreases, the anti-roll capability decreases, and the safety and reliability deteriorate
