Abstract

A sedan with auxiliary wheel has two main wheels for bearing load and transferring power and two auxiliary wheels capable of being lifted freely. At low speed or in park state, two auxiliary wheels are in touch with ground. At high speed, they are lifted up. Its advantages include simple structure like motorcycle and high safety and comfort similar to 4-wheel sedan.

Description

Sedan with auxiliary wheel

Sedan with auxiliary wheel belongs to mechanical manufacturing field, is a kind of simple in structure, easy to use, the new kind vehicle of ride comfort.

Any vehicle has all required two kinds of state of equilibriums: the one, and static balancing promptly stops, the balance of starting and low cruise state; The 2nd, dynamical equilibrium, the i.e. balance of high-speed cruising state.Motor bike grows up on the bicycle basis, dynamically utilizing inertia to realize balance, has only two wheels, have simple in structure, easy to manufacture, light and flexible, oil consumption few, be subjected to road limits little, drive easily advantages such as (can without special training).But in static state, promptly start to walk, when stopping and speed when very slow, can not keep self balance, must help by manpower.Therefore so motor bike can not seal, seat can not design by comfortable requirement fully, takes uncomfortablely again, drives tiredly easily, is subjected to wind, Exposure to Sunlight, drenching with rain shortcoming such as influences.And safety is relatively poor, and the occupant is in the directly state of injury that is subjected in having an accident.Four-wheel car grow up by the static balancing thinking, and are very stable in static state, ride comfort.But from sport dynamics, object is not to have the strong point more than three could realize balance when high-speed motion, and the strong point is many can to influence its exercise performance on the contrary.When the high speed revolution, only need a strong point as gyro,, change motionless on the contrary if three not in-line strong points are arranged.Therefore, four-wheel car and not in full conformity with the sport dynamics principle, this brings a series of problems for design, manufacturing and use: the one, complex structure, technical requirements height.Will realize turning to flexibly as four-wheeled, drive wheel must have diff; Brake requires two front-wheels or two trailing wheels to be consistent, otherwise in case brake monolaterally, danger will occur; The 2nd, performance is limited.The turned influence of centnifugal force of four-wheeled can only elect aspect speed, dead weight of vehicle, the off-road capability.If raising speed alleviates car weight, must reduce the chassis, sacrifice off-road capability.Though three-wheel vehicle has two-wheeled motor vehicle and some advantage of four-wheeled, move not steady, the easier rollover, speed is restricted.

In sum,, preferably there are four wheels to support, in dynamically the most handy two wheels operation in static state if vehicle is not considered carrying or bearing capacity when very little.Sedan with auxiliary wheel designs two main wheels and two auxiliary wheels according to the different requirements of two kinds of state of equilibriums of vehicle.Two main wheels are used for carrying and transferring power, and two auxiliary wheels are installed on the support that is risen and fallen by manpower or electronic control, can freely put down to land and rise built on stilts.In starting, stop or during low-speed motion, put down two auxiliary wheels, car is 4 supports, realizes steady stability; When high-speed motion, rise two auxiliary wheels, car is realized smooth operation by inertia balance.

Sedan with auxiliary wheel has the advantage of four-wheeled and two-wheeled motor vehicle.(1) simple in structure, easy to manufacture.Sedan with auxiliary wheel is compared with motor bike, though increased by two little auxiliary wheels and alighting gear, itself structure is comparatively simple, and only uses at low speed with when stopping, and technical requirements is low.Other device as turn to identically with motor bike with power transmission does not have the steering hardware, diff of four-wheeled such as complexity etc.(2) ride comfort.Sedan with auxiliary wheel does not need manpower to help in starting, the same with four-wheeled when stopping with low-speed motion, need not adjust health and direction keeps balance yet; When high-speed motion, its stable degree is higher relatively again, thus can realize totally-enclosed, by comfortable safety requirements design seat.

Manufacturing and designing the required various technology of sedan with auxiliary wheel all is existing proven technique, and its novelty is the combination of these technology.The auxiliary wheel alighting gear can manufacture and design with reference to undercarriage, take mechanical drive, oilgear and electronic mode as required, direction, power transmission can manufacture and design with reference to motor bike, totally-enclosed vehicle body can manufacture and design with reference to three-wheel vehicle and four-wheel car, and driving engine, change-speed box etc. can be selected current version for use.

Accompanying drawing 1 is the jockey pulley take-off and landing device by manpower control.When parking or low cruise, pin is depressed pedal and is made the card spring stuck, and jockey pulley is landed.When high-speed cruising, unclamp the card spring, jockey pulley rises built on stilts under the effect of alighting gear controlling spring elastic force.

Accompanying drawing 2 is by motor-driven jockey pulley take-off and landing device.Replace rising and falling of manpower control auxiliary wheel by motor and worm gearing.

Accompanying drawing 3 and accompanying drawing 4 are the integral structure of sedan with auxiliary wheel, are respectively not seal and totally-enclosed, low speed and two kinds of situations of high-speed cruising.Accompanying drawing 5 and accompanying drawing 6 are the integral structure of painted sedan with auxiliary wheel.

Claims

Sedan with auxiliary wheel comprehensively adopts 4 balance support technology of motor bike inertia balance technology and four-wheel car, has the advantage of motor bike and four-wheel car, compares with existing vehicle, it is characterized in that:

1, has and to land and can the unsettled auxiliary wheel of built on stilts;
But 2, both four-wheel walkings, but two-wheel running again.
