Abstract
A four-front-wheel steering device consists of a built-front steering driving device of an engine and four front wheels; the built-front steering driving device of the engine can be arranged on the front steering drive axle of an auto; two front-wheel handle are arranged between two front wheels of the front axle to change the original pushing-back type into pulling-forward type, thereby keeping the balance of the whole auto, enhancing the working efficiency of the engine and avoiding the accidents of tyre bursting and rollover. The utility model can fully play and improve the working efficiency of auto-engines; and the power active force can be met by increasing the number of the tyre; the utility model has the anti- side-sliding and anti-side-overturning abilities, and can reduce the rolling resistance and also can improve the passing capacity; with low center of gravity, the utility model can reduce the vibration, and improve comfort; driving by four front wheels, the utility model has better power direction to make the operation convenient and flexible.
Description
Technical field
The utility model belongs to automotive proplsion, four-wheel steering actuating device before particularly a kind of automobile.
Background technology
Present automobile (not comprising cross-country car and special purpose vehicle) generally all is that rear axle is an axle drive shaft, front axle is a driven shaft, when load-carrying is travelled, axle drive shaft will carried very big weight resistance on the back and push away and drive a vehicle, its power concentration is between axle and wheel, so power decentralized as the front axle of driven shaft, has only been adorned two wheels and but will have been carried very big pressure, it is very not steady to travel, inefficiency, side slope, turning are easy to cause the headstock Shift of Focus, and it is unreliable to brake, anti-side rollover resistant capability is poor, it should be noted that: front axle is only established single-wheel, in case blow out, accident is unavoidable.The automobile of single-wheel structure before this rear drive, in the driving history in the past, the accident that quick-fried preceding born of the same parents cause happens occasionally.
Summary of the invention
The purpose of this utility model provides the preceding four-wheel steering actuating device of a kind of automobile, the engine behind front wheel steer-drive is installed on the automobile front axle, and it is pull-type before between two front-wheels of propons, installing two front-wheels additional former back driving being changed into, kept the car load balance, improve engine operation efficient height, prevent to blow out, avoid roll-over accident.
The utility model is made up of engine behind front wheel steer-drive and four front-wheels, steering drive axle before automobile (1) is gone up engine behind front wheel steer-drive (2) is installed, install two front-wheels (3) additional between two front-wheels (4) of steering drive axle before automobile (1), front-wheel (3) is identical with front-wheel (4).
The automotive engine work efficiency can be brought into play and improve to the utility model; Increase the tire number, satisfy power traction power.Have anti-side sliding, side rollover resistant capability, reduce rolling resistance, improve traffic potential; The full car weight heart is low, can reduce vibration, increases traveling comfort; Before four wheel drive, have power direction preferably, make the steering operation light and flexible.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, go up installation engine behind front wheel steer-drive (2) at automobile front axle (1), install two front-wheels (3) additional between two front-wheels (4) of propons (1), front-wheel (3) is identical with front-wheel (4).Propons (1) can be driving or does not have driving.Two-wheel setting can effectively prevent the accident that single-wheel is blown out and brought like that, still can cruising when the tire of a quick-fried tire or two symmetries, played the effect of double insurance, and ensured the safety factor of driving greatly.The present invention is fit to big-and-middle-sized lorry, manned passenger vehicle, dangerous material load wagon and trailer and superimposed trailer.
Claims (1)
1. four-wheel steering actuating device before the automobile, form by engine behind front wheel steer-drive and four front-wheels, it is characterized in that upward installation engine behind front wheel steer-drive (2) of steering drive axle before automobile (1), install two front-wheels (3) additional between two front-wheels (4) of steering drive axle before automobile (1), front-wheel (3) is identical with front-wheel (4).
