Description

The automobile front that has steering gear

The utility model relates to a kind of automobile automobile front that night, road lighting was used.

The head light of existing automobile is to be fixedly mounted on the automotive front end both sides, and its key lighting zone is positioned at the dead ahead of automobile.If automobile turning, driver vision will turn to steered wheel (front-wheel).Because automobile front is to be fixedly mounted on the vehicle body, there is not the steering gear that can match with the automotive steering steering unit, this just makes and forms an angle of lag between the key lighting light of head light and the automobile steering roller (that is pilot's line of vision), has only and waits vehicle body to turn to back head light key lighting light just to shine on the road surface after turning to.Can find out that thus in automobile turning, chaufeur is difficult in time see clearly the turning condition of road surface, therefore very easily cause traffic accident, jeopardize traffic safety, particularly even more serious to the harm of traveling automobile on winding road, mountain area.

In view of the foregoing, the purpose of this utility model provides a kind of automobile front that has steering gear, makes it convenient and matches with the automotive steering steering unit, and what realization automobile turning and car light turned to carries out synchronously, makes it to guarantee traffic safety.

The purpose of this utility model is achieved by the following technical solution: it comprises automobile front, it is characterized in that, be provided with the steering gear that places in the housing in the back of this head light, this transmission device comprises main shaft and the driven shaft of two main shaft both sides that are placed in and the tooth bar in two two driven shafts outsides that are placed in that places center in the shell, be with semicircle transmission gear to be meshed on the main shaft with institute's With a driven gear on two driven shafts, two driven gears are meshed with two tooth bars respectively, the both sides hinge joint of the front end of two tooth bars and automobile front base, main shaft and propulsion source output shaft are made gear transmission.Control the forward and reverse rotation of propulsion source output shaft by handling automotive steering, and drive the forward and reverse rotation of main shaft with this, by a rotation in two driven gears of the corresponding drive of the semicircle transmission gear on the main shaft, and drive respective rack and stretch out forward, it is synchronous to make it to realize that automobile front and automobile steering roller turn to.

Improve the shock-resistance features of head light and transmission device for son, guarantee reliable and stable the turning to of head light, also can be provided with on main shaft and the corresponding semicircle brake shoe expander of semicircle transmission gear, this brake shoe expander divides the stop mechanism of controlling two driven shafts with brake cone, brake silpper, brake rocker arm and brake silpper spreading spring formation on corresponding its both sides slide body that is placed in.Make it to guarantee a driven shaft rotation, another driven shaft braking; Tooth bar and tooth bar body are connected and the tooth bar body embeds in the set chute of raceway body, and the bottom surface of this chute is provided with one group of drive balls, and purpose is to guarantee the motion of tooth bar body steadily, and flexibly, loss reduces friction.

Advantage of the present utility model is to have set up on the basis of head light can be convenient to match with automotive steering the transmission device that the control head light turns to, making it this head light is easy to realize turning to synchronously with automobile steering roller, guarantee traffic safety, in addition, aseismicity is good, and head light is turned to steadily.

Below in conjunction with accompanying drawing the utility model is explained
