Description

Automobile auxiliary steering mechanism

The utility model relates to self-propelled vehicle, belongs to a kind of steering hardware of self-propelled vehicle.

Along with the raising of people's living standard, the urbanization of working environment, people more and more rely on automobile, so the productive output of automobile and also just grow with each passing day with the car amount, and road is also more and more crowded.Situations such as turning or tune must take place in automobile under steam, and existing auto steerer is the tie rod linkage that a kind of and preceding spindle nose links to each other, and tie rod linkage links to each other with the direction machine of being operated by bearing circle by drag link.Such steering hardware, steering dish make front-wheel change angle and the travel direction of conversion automobile.Because this steering hardware is subjected to the restriction of other device, steering angle can not be excessive, and when excessive as if steering angle, automobile influences safe driving with regard to being difficult to control under running at high speed, then if will reverse end for end, certainly will bigger radius of turn will be arranged.Therefore, under the condition of existing steering hardware, during tune, generally can only adopt engage a gear, steering dish to solve with the way of advancing or move backward, operation is quite complicated, effort, wastes fuel and has many safety hazard, and enough wide road surface or vacant lot must be arranged, so one meets the reversing tune in modern city, just causes obstruction to traffic easily.

The purpose of this utility model be for provide a kind of automobile is done in the original place about the automobile assistant steering device that turns to of 360 degree, make automobile can be on any travel pivot turn, and tune processing ease saves time, laborsaving safe again, economical.

Realize in the technical solution of the utility model of above-mentioned purpose that including a rhombus crane, end is that the pulling shaft, of optical axis section is by motor-operated speed reduction gearing and a steering wheel that lands for the thread segment other end.Said rhombus crane, the end of each pole is articulated structure in its four pole, and then this rhombus crane can be done to open (rise) or draw (decline) shape in.The member that makes the rhombus crane do dipping and heaving in the utility model is a pulling shaft, this pulling shaft is set in the angle body of two level attitudes of crane, wherein, the spiral section of pulling shaft is meshed with the negative thread of setting in the body of angle, optical axis Duan Ze is set in the axle sleeve that is provided with in another angle body, and be fixed with a transmission gear at the axle head of this optical axis section, this transmission gear is meshed with final stage gear by motor-operated speed reduction gearing, when then pulling shaft is rotated by the speed reduction gearing drive by electrical motor, one jiao of body with negative thread promptly moves along pulling shaft, and dipping and heaving promptly takes place crane.The said steering wheel that lands is arranged on body place, crane lower position angle, and crane is fixed near automobile front axle or the rear axle bottom of frame with body place, angle, top position, then (first half of crane rises when crane rises, lower part descends), the steering wheel that lands descends, until load-bearing and automotive front (or rear portion) jack-up.After anterior jack-up, automobile is three points of contact---and steering wheel and two groups of trailing wheels land.Angle of inclination (these angle of inclination are to decide according to size and this Unit Installation position of wheelbase, wheelspan) have been put because of giving facing to the ground steering wheel when mounted, at this moment, start a car and when handling engage a gear, differential takes place at the steering wheel that lands under because of the drag effect of giving the angle of inclination put and producing and rotates in back wheels, be a steering wheel and one group of trailing wheel around another group trailing wheel rotation, automobile promptly reaches the purpose of tune in the original place rotation.

The utility model also can be at start a car not and is made the automobile pivot turn, at this moment, can have engine installation on the steering wheel that lands.For this reason, can on the steering wheel that lands, fix a transmission gear in the utility model, and on rhombus crane lower position hinge pedestal, fix one group of gear case that includes driving force motor and speed reduction gearing, and the final stage gear of speed reduction gearing is meshed with transmission gear on the steering wheel.The steering wheel structure that lands like this, when chaufeur in operator's compartment during actuating motor, this electrical motor promptly drives the steering wheel that lands and rotates, at this moment, steering wheel becomes the power wheel of somerset.

Because of the load carrying ability of automobile has difference, under-carriage also has the branch of height, and the automobile lower for under-carriage is hinged on same bearing pin the end of adjacent two poles in four poles of rhombus crane.Use for adapting to high under-carriage automobile, the utility model is as long as change the articulated structure of rhombus crane, promptly the end of adjacent two poles in four poles of rhombus crane is hinged respectively on two bearing pins that are arranged on the even hinge block, improves the height of crane with the relative distance up and down that increases by two bearing pins.The benefit of doing like this is that also the weight of automobile can separately be born by two bearing pins, has improved the safety of device.

Therefore, because of the utility model is arranged on side under near the forward and backward axletree the car, when the rotation pulling shaft rises the rhombus crane, after landing, promptly automotive front (or rear portion) jacking is risen the steering wheel that lands, at this moment after starting and handling automobile (or startup electrical motor relevant) with landing wheel, automobile promptly by land steering wheel and wherein one group of automotive wheels that lands rotate and reach the purpose of automobile pivot turn around another group automotive wheels that lands.After automobile mixes up head, restart that electrical motor makes pulling shaft counter-rotating and the gathering of rhombus crane, four groups of automotive wheels promptly all land, and can handle automobile and move on.This shows that the utility model is simple in structure, easy to operate, solved the difficult problem that automobile is reversed end for end on narrow and small road.
