A kind of illumination equipment with steering box steering box motor-car
Affiliated technical field
The utility model relates to the illumination equipment that uses on a kind of self-propelled vehicle that turns to steering box, particularly relates to the illumination equipment of a kind of employed steering box by the driven off by shaft self-propelled vehicle of spindle arm.
Background technology
At present, employed steering box is by the illumination equipment of the self-propelled vehicle of steering arm shaft transmission (as steering boxs such as worm screw roller type, cam and lever with fixed stud, circulating ball type, worm-and-wheels), as the employed illumination equipment of heavy motor vehicle, mainly comprise head light, captive joint between described head light and the car body.When self-propelled vehicle turned at night,, have a strong impact on pilot's line of vision, so produce the shortcoming of potential safety hazard when its existence makes the self-propelled vehicle night running because the head light of illumination equipment can not make to have large stretch of lighting blind zone on the direct of travel with wheel steering.
Summary of the invention
In order to solve the problem that above-mentioned illumination equipment exists, the illumination equipment that the utility model provides, the lighting blind zone in the time of can reducing self-propelled vehicle and turn night on the direct of travel improves the safety of driving.
A kind of illumination equipment of the present utility model with steering box steering box motor-car, comprise head light, be provided with the turning cylinder that is fixedly linked with head light, be provided with gangbar between the turning cylinder of described head light, described turning cylinder links to each other with described gangbar by connecting arm, between described connecting arm and the described turning cylinder for captiveing joint, be connected for axle between described connecting arm and the described gangbar, described turning cylinder is provided with the transmission arm of captiveing joint with it, this turning cylinder links to each other with transmission device by described transmission arm, also is provided with the transmission arm that links to each other with described transmission device in addition.The effect of described turning cylinder is that head light can be rotated with respect to car body.The effect that described gangbar is set is to make all head lights realize rotating synchronously.The effect that described transmission arm, transmission device, transmission arm are set is by transmission arm is connected with motor turning machine steering arm shaft, the driving torque of motor turning machine is passed to transmission arm through transmission arm, transmission device, drive turning cylinder driving head light by transmission arm and turn to together with front-wheel.Described transmission arm can be multiple parts such as crank, tooth fan, gear, belt wheel, described transmission device can be multiple structure members such as pull bar, hydraulic gear, tooth bar, chain, driving band, and described transmission arm can be multiple parts such as crank, tooth fan, gear, belt wheel.
Because by described transmission arm is connected with motor turning machine steering arm shaft, can pass to turning cylinder and gangbar to motor turning machine steering arm shaft driving torque by described transmission arm, transmission device and transmission arm, driving head light turns to front-wheel, so the lighting blind zone when the utility model has reached and reduced self-propelled vehicle and turn night on the direct of travel improves the purpose of drive safety.
The beneficial effects of the utility model be when self-propelled vehicle is turned night on the direct of travel lighting blind zone reduce, improve travel safety.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 assembles the use scheme drawing for embodiment of the present utility model.
Among the figure 1, head light, 2, head light, 3, lamp support, 4, steering box, 5, transmission arm, 6, the front-wheel steering arm, 7, drag link, 8, the vertical pulling lever arm, 9, front axle, 10, turning cylinder, 11, turning cylinder, 12, gangbar, 13, connecting arm, 14, connecting arm, 15, transmission device, 16, steering arm shaft, 17, transmission arm.
The specific embodiment
A kind of illumination equipment as shown in Figure 1 with steering box steering box motor-car, comprise head light 1,2, be provided with and head light 1,2 turning cylinders that are fixedly linked 10, ll, described head light 1,2 turning cylinder 10, be provided with gangbar 12 between 11, described turning cylinder 10,11 by connecting arm 14,13 link to each other with described gangbar 12, described connecting arm 13,14 with described turning cylinder 11, it between 10 captive joint, described connecting arm 13,14 with described gangbar 12 between for the axle be connected, described turning cylinder 10 is provided with the transmission arm 5 of captiveing joint with it, this turning cylinder l0 links to each other with transmission device 15 by described transmission arm 5, also is provided with the transmission arm 17 that links to each other with described transmission device 15 in addition.The effective length L1 of described transmission arm 5 equals the effective length L2 of self-propelled vehicle vertical pulling lever arm 8 and the ratio of the effective length D2 of front wheels of motor-vehicles spindle arm 6 with the ratio of the effective length D1 of described transmission arm.Because L1: D1=L2: D2 can guarantee that head light 1,2 and front-wheel turn to synchronously, thereby can eliminate the lighting blind zone on the direct of travel well.Described transmission arm 5 effective length L1 are meant that described transmission arm 5 is connected center-point and is connected center-point with turning cylinder 10 in the distance between the projection on the same horizontal surface to it with transmission device 15.Described transmission arm effective length D1 is meant that described transmission arm 17 is connected center-point and is connected center-point in the distance between the projection on the same vertical surface to it with steering box 4 steering arm shafts 16 with transmission device 15.Self-propelled vehicle vertical pulling lever arm 8 effective length L2 are meant that described vertical pulling lever arm 8 is connected center-point and is connected between the center-point distance of projection on same horizontal surface with front axle 9 to it with drag link 7.Front wheels of motor-vehicles spindle arm 6 effective length D2 are meant that front-wheel steering arm 6 is connected center-point in the distance between the projection on the same vertical surface with the center-point that is connected of steering box 4 steering arm shafts 16 to it with drag link 7.Described transmission arm 5 is a crank structure, and described transmission arm 17 is a crank structure, and described transmission device 15 comprises a connecting rod, is connected for axle between this connecting rod and described transmission arm 17, the transmission arm 5.For an axle purpose of connecting is to be connected described transmission arm 17, transmission arm 5, and connecting rod can be moved between described connecting rod and described transmission arm 17, the transmission arm 5 with respect to described transmission arm 17, transmission arm 5.This connection structure combination of described transmission arm 5, transmission arm 17, transmission device 15 has simple in structure, convenient for installation and maintenance, is easy to realize the advantage that turns to synchronously.
During installation, earlier lamp support 3 is fixedly installed in the body of motor vehicle front end, turning cylinder 10,11 with described head light 1,2 is installed on the lamp support 3 again, described turning cylinder 10,11 can be rotated with respect to lamp support 3, described transmission arm 17 is linked to each other with motor turning machine 4 steering arm shafts 16 get final product.
