Technical Field

The invention relates to the technical field of automobile articles, in particular to a vehicle auxiliary mechanism.

Background

The traditional cross-country vehicle is limited by a plurality of factors in the process of cross-country or climbing, for example, the angle is too large, the vehicle cannot normally advance due to insufficient power or insufficient adhesion between tires and the road surface, and even the vehicle can slide and turn on one's side. Meanwhile, the mass center of the whole cross-country vehicle is generally at a higher position, so that adverse effects can be caused when the vehicle descends a large-angle slope, if higher deceleration occurs in the driving process, the vehicle can be turned forwards, and the safety of a driver is seriously threatened. In the large-angle lateral driving process, the vehicle can sideslip or even turn over due to the influence of a vehicle suspension structure, the generally higher influence of the mass center height of the off-road vehicle and the influence of the adhesive force of the road surface and the tires. Meanwhile, if a large amount of manual work cannot be carried to clear the obstacles in the cross-country process, vehicles without related auxiliary mechanisms cannot pass through.

Traditional complementary unit is for example the capstan winch, and the manual work of adoption such as tyre chain is arranged and function singleness mostly, can only carry out simple getting rid of poverty, can not quick assurance vehicle pass through and have the artificial condition that can't arrange complementary unit.

Under the extreme off-road working condition of the off-road vehicle, the vehicle is difficult to have higher trafficability without the help of an auxiliary device under the influence of the vehicle structure and the road adhesion. Conventional off-road auxiliary devices such as winches or snow chains can only assist a vehicle in performing an off-road function in a specific scene and require manual arrangement in advance. And a scene that the auxiliary device cannot be arranged by manpower often occurs, and manpower is seriously wasted. And the device can not assist the vehicle to run laterally at a large angle. The prior art or products only provide assistance for the cross-country vehicle to get rid of difficulties on a low-attachment road surface or pull the vehicle to go up a slope, and can not solve the stability problems of the vehicle in large-angle slope ascending, large-angle slope descending and large-angle lateral running.

Disclosure of Invention

In view of the above, the invention provides an off-road driving assisting mechanism which can be used as power and support in an uphill or climbing process, and solves the problem that a traditional off-road vehicle fails to climb due to insufficient power or insufficient adhesive force or slides down and turns over in a mountain off-road climbing process. Meanwhile, the support can be used as an auxiliary support in the process of descending a steep slope, and the phenomenon of overturning is prevented. In the process of large-angle lateral driving, the auxiliary device can be used as a lateral support of the vehicle, and the stability of the vehicle in the lateral driving process is ensured. If the obstacles which cannot be manually carried and cleared and cannot be overtopped by the vehicle appear in the driving process, the obstacles can be carried and cleared through the auxiliary mechanism, and the passing performance of the vehicle is guaranteed. Meanwhile, the auxiliary mechanism can replace manpower to carry and load larger materials, so that manpower is saved, and particularly, the physical strength of people is guaranteed to be very important in the high-temperature or high-altitude anoxic environment in the field. The auxiliary device provided by the invention adopts the device as a power source, is firmly assembled with the vehicle body, does not need to be arranged by manpower for a long time, has rich application scenes and can realize rich functionality.
