Abstract

The utility model relates to a turning device for front big lamps of drive vehicles, which is provided with a driven unit which is controlled by a turning mechanism of a motor vehicle, wherein the output end of the driven unit is connected with a front big vehicle lamp which can be turned right and left. The driven unit arranged on the utility model can cause the front big lamp of the vehicle to randomly and synchronously rotate along with a front vehicle wheel. A driver can clearly see a road condition away from a crooked road. Consequently, traffic accidents generated due to indistinct road conditions can be prevented. In addition, the device is realized only through a simple mechanical component. Therefore, the utility model has the advantages of simple structure and lower cost.

Description

Drive car head light steering hardware

The utility model relates to a kind of car head light steering hardware that is used to drive.

For general self-propelled vehicle, its car head light is provided with two usually, and it is mainly used in the road conditions that indicate the place ahead when driving a vehicle night.Yet, the head light of installing on the existing self-propelled vehicle can only be adjusted far and near light up and down, and its light beam is almost identical with the direction that car advances, it is the car head light that most of light beam and vehicle body can not form the random this structure in angle of inclination, when car travels when detour particularly travels at the big detour of radian, its light beam that sends can only rotate gradually with the rotation of vehicle body, rather than with wheel, so, the light beam that it sends will lag behind the light beam that the driver will see path, the place ahead clearly, cause the driver can not see clearly the detour that travels road conditions far away.For this reason, use car head light of the prior art, the driver is expert at and reaches when stating detour, and unique effective solution is exactly Reduced Speed Now, even so, also often because seeing road conditions at a distance traffic accident does not take place.

Task of the present utility model provides a kind of driving car head light steering hardware, and this device can make the car head light move and rotate synchronously with the verticillate right-hand rotation of front truck, and then makes the driver can see any detour road conditions far away easily clearly, in order to overcome above-mentioned weak point.

For finishing above-mentioned task, device described in the utility model have be controlled by steering mechanism of motor vehicle with moving cell, and make this with the mouth of moving cell with can about the car head light that turns to join.

Described input end with moving cell can be directly and the steering swivel of vehicle steering mechanism or join with Steering gear that bearing circle joins.

Described have at least one variable displacement type hydraulic actuating cylinder with moving cell, and piston and a retarder in this hydraulic actuating cylinder join, and its mouth and a swing type hydraulic cylinder join.

The gear of installing on the input end of described retarder and the described wheel steering post is connected.

Also be provided with the power-transfer clutch that can be separated on the described retarder with the gear on the wheel steering post.

But described have one directly or the moving part that joins by power-transfer clutch and car steering swivel operating station with moving cell, this moving part be again by can making the tumbler that turns to about the car head light join, or moving part can be directly or the lateral connecting rod by power-transfer clutch and steering swivel join.

This device is controlled a follow-up unit by steering mechanism of motor vehicle, the car head light can be rotated with front vehicle wheel randomly synchronously, like this, car is when travelling detour, the light beam that its head light sent just can be ahead of the steering angle of vehicle body, make the driver can see detour road conditions far away clearly, thereby can avoid because of the not clear traffic accident that takes place of road conditions; In addition, this device only realizes by simple mechanical part, so, its structure is also quite simple, cost is also lower; Rotating the car head light does not simultaneously need big rotating torque, so, use this device can not produce any influence to the steering hardware of car:

Below in conjunction with drawings and Examples the utility model is elaborated.

Accompanying drawing 1 is the surface structure scheme drawing of this device when being controlled by bearing circle;

Accompanying drawing 2 is section-drawings of variable displacement type hydraulic actuating cylinder and swing type hydraulic cylinder among Fig. 1;

Accompanying drawing 3 is this device surface structure scheme drawings when being controlled by the car steering swivel.

Referring to accompanying drawing 1 and Fig. 2, they provide this schematic appearance of installing a kind of structure: givenly among the figure comprise retarder 11 with moving cell 1, variable displacement type hydraulic actuating cylinder 13 and swing type hydraulic cylinder 16, and the gear 10 that is installed in car wheel steering post bottom.

Wherein, retarder 11 can be made of multipole reducing gear as required, because this kind retarder 11 is that those of ordinary skills just can realize without creative work, so do not provide concrete structure in the accompanying drawing.Retarder 11 tops are provided with a power-transfer clutch 12, and it can be made of two-position four way change valve, and promptly manual and electronic two parts all can make the change-over valve action respectively.The input end gear of retarder 11 is meshed with gear 10 on the Steering gear that is fixed in the bearing circle bottom, when power-transfer clutch 12 is in closed condition, can rotate by driven gear 10 as long as Steering gear rotates, thereby makes the predetermined rotating torque of retarder 11 outputs.

Secondly, the piston 14 of setting is connected on the mouth of retarder 11 and the variable displacement type hydraulic actuating cylinder 13.Piston 14 adopts double rod types, and the end that it extend into retarder 11 is provided with the screw thread 141 that the output interface with this retarder is complementary, and when retarder 11 actions, can make the axial action of piston 14 along hydraulic actuating cylinder 13.Two exits of hydraulic actuating cylinder 13 join with the oil storage portion on swing type hydraulic cylinder 16 both sides respectively by pipe fitting 15, when the hydraulic oil quantitative change at two ends in the variable displacement type hydraulic actuating cylinder 13, can drive rotor 17 actions in the swing type hydraulic cylinder 16, thereby can drive the car head light rotates by predetermined direction, when rotor 17 actions, can make 18 actions of car head light: two car head lights 18 can be respectively by 16 controls of two swing type hydraulic cylinders, also can with connecting rod 19 two head lights be connected in series earlier, by 16 controls of a swing type hydraulic cylinder, make its synchronization action then.

Referring to Fig. 3, it provides the surface structure of another embodiment of the utility model.As can be seen, comprise a moving part 22 on the intermediate rod 24 that can be directly installed on car steering swivel 21 or join with steering swivel 21 with moving cell 2 from accompanying drawing, this moving part is again by making the tumbler 23 that turns to about the car head light join with the car head light.In addition, moving part 22 also can be by being connected with steering swivel 21 behind the above-mentioned retarder again, and this depends primarily on moving part 22 and steering swivel bonded assembly position.
