Problems solved by technology
However, in the field of commercial vehicles, because the steering axle load is much larger than that of electric vehicles, the electric power steering system is difficult to apply, and the volume of commercial vehicles is very large, which makes reversing extremely difficult.
When a commercial vehicle is reversing, in order to reverse safely, it is usually necessary for someone to instruct the driver to reversing under the car, or the driver gets on and off the car several times to observe the reversing trajectory of the vehicle, which increases labor costs and reduces work efficiency

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] to combine Figure 1 to Figure 5 , the commercial vehicle reverse assist device, which includes: a planetary gear train 1, an intermediate gear 2, a first stepping motor 3, a second stepping motor 4 and a block 5, wherein the planetary gear train includes sun gears meshing with each other 11 and planetary gear 12 and planet carrier 13.
[0018] The specific connection relationship is as follows: the intermediate gear 2 is set on the steering column of the automobile and meshes with the planetary gear set in the planetary gear train. The output shaft of the first stepping motor 3 is connected with the sun gear so that it can drive the sun gear to rotate. The bottom of the planetary carrier in the gear train 1 is provided with a plurality of stop columns, and the output end of the second stepping motor is connected with the stop block 5 .
[0019] When the drive...

The invention provides an electric-controlled commercial vehicle reversing auxiliary device which overcomes the defect that one person needs to get off a commercial vehicle to command or a driver needs to get on or off the commercial vehicle repeatedly to finish reversing the commercial vehicle in the prior art. By means of the commercial vehicle reversing auxiliary device, the driver can get off the commercial vehicle to finish reversing the commercial vehicle by self. Thus, the labor cost is reduced, the labor intensity is reduced, and the work efficiency is improved. The commercial vehicle reversing auxiliary device is characterized by comprising a planetary gear train, an intermediate gear, a first stepping motor, a second stepping motor and a stopping block. A vehicle steering column is sleeved by the intermediate gear, the intermediate gear is further meshed with a planetary gear set of the planetary gear train, the first stepping motor can drive a sun gear of the planetary gear train to rotate, a plurality of blocking columns are arranged at the bottom of a planetary frame of the planetary gear train, and the output end of the second stepping motor is connected with the stopping block. When auxiliary vehicle reversing is needed, the second stepping motor can drive the stopping block to rotate to be in butt joint with the blocking columns at the bottom of the planetary frame, and the first stepping motor can drive the vehicle steering column to rotate sequentially through the sun gear, a planetary gear and the intermediate gear.
Description
technical field [0001] The invention relates to a backing auxiliary device, in particular to a backing auxiliary device on a commercial vehicle. Background technique [0002] As a mechatronics product, automobile has been valued by more and more people for its convenience. Whether it is convenient to reverse the car directly affects the convenience of the car. In the field of passenger vehicles, with the popularization of electric power steering systems, convenient functions such as automatic parking have been widely used. However, in the field of commercial vehicles, because the steering axle load is much larger than that of electric vehicles, the electric power steering system is difficult to apply, and the volume of commercial vehicles is very large, which makes reversing extremely difficult. When a commercial vehicle is reversing, in order to reverse safely, it is usually necessary for someone to instruct the driver to reversing under the car, or the driver gets on and...
