Technical Field

The invention relates to a mechanical auxiliary device in the technical field of automobile accessories, and particularly discloses a wheel hub auxiliary device for vehicle escaping.

Background

Vehicles are common transportation means and necessary tools for various engineering operations in daily life. However, the vehicle does not always run on a flat road under good weather conditions, and the vehicle is prone to driving troubles due to weather changes or road condition changes. For example, the tires of the vehicles can slip on the ice and snow road surface caused by severe weather such as rain, snow, ice and the like, and the vehicles are easy to lose control; when the road surface is muddy or various obstacles and other complex road conditions are met, particularly in the engineering operation process of an engineering operation vehicle, the situation that tires slip, sink deeply or the obstacles block the tires and cannot climb over the obstacles easily occurs.

Currently, there are two ways to solve the above-mentioned problem of getting stuck in a vehicle: one is to bind the anti-skid chains on the wheels, although the mode is simple, the anti-skid chains are directly contacted with the ground to cause self abrasion, and when the vehicle runs on uneven mountain road surfaces with more obstacles or in the field, the vehicle has no driving advantage for climbing the obstacles, and meanwhile, if the mud degree of the ground is more serious, the anti-skid effect cannot be ensured; the other type is that an adjustable anti-skid device is additionally arranged on the wheel hub, but the existing anti-skid device basically has a complex structure, more component parts and more grounding support legs, so that the manufacturing, processing and assembling difficulty is higher, the use cost is higher, and the stable running of the vehicle is also difficult to a certain extent. Meanwhile, the more component parts, the inconvenience of maintenance and replacement when the parts are damaged is also implied, and the use cost is further increased.

Disclosure of Invention

The invention aims to solve the defects of the prior art and designs a wheel hub auxiliary device for vehicle escaping, when a vehicle is trapped in mud or is trapped in a rugged road with obstacles, the wheel feet of the auxiliary device additionally arranged on the wheel hub of a power wheel are unfolded, and each power wheel of the vehicle drives the vehicle to move forwards or back backwards in a manner similar to walking, so that the vehicle is helped to escape smoothly.

The invention is realized by the following steps: the utility model provides a wheel hub auxiliary device for vehicle is stranded, includes supplementary fixed wheel hub and locates the caster of supplementary fixed wheel hub surface, its characterized in that: the caster be equipped with one or more, the caster when for the expansion state, its one end be the stiff end, be fixed in through locking bolt group supplementary fixed wheel hub surface, the other end is for stretching out the ground end of touching of wheel surface, the end that contacts to the ground of caster sets up to convex bellied stabilizer blade, still is equipped with supporting lug in the stabilizer blade inboard, is an contained angle with the stabilizer blade, makes the end that contacts to the ground of caster be "people" word form, supplementary fixed wheel hub on be equipped with a plurality of bolt holes that are used for cooperation locking bolt group to carry out the fixing to the caster, supplementary fixed wheel hub still be equipped with a plurality of through-holes of being connected the usefulness with the wheel for wheel hub connecting bolt hole, wheel hub connecting bolt hole length be 5mm ~ 2000 mm.

When the wheel legs are provided with two or more than two wheel legs, the wheel legs are required to be uniformly distributed on the outer surface of the auxiliary fixed wheel hub, a plurality of groups of locking bolt groups correspondingly arranged on the wheel legs are uniformly distributed in the plane of the auxiliary fixed wheel hub, and each wheel leg is provided with at least 3 fixed points which are not positioned on the same straight line. The wheel foot is selected from a stainless steel wheel foot, an aluminum alloy wheel foot or a wheel foot made of the same material as the original vehicle wheel hub. The ground contact end of the caster is provided with a rubber protective layer, and the inner side of the herringbone ground contact end of the caster is provided with a groove for clamping the edge of the rubber protective layer. The supporting lug at the ground contacting end of the wheel foot and the supporting leg form an included angle of 30-120 degrees. The size and dimension of the caster are matched with the vehicle type, the axial thickness of the outer side edge of the caster and the ground contact end of the caster in the shape of the Chinese character 'ren' is set to be 50-2000 mm according to the corresponding load carrying capacity and requirement of the specific vehicle type, and the radial thickness of the outer side edge of the caster is 1-300 mm.

When the two caster wheels are arranged, the outer side edges of the two caster wheels are respectively arc-shaped, the caster wheels are provided with fixing pin shaft holes and are connected with the auxiliary fixing wheel hub through fixing pin shafts, and the caster wheels rotate to the proper position around the fixing pin shafts to enter an unfolding or folding state. The whole body is S-shaped or reverse S-shaped when in the unfolding state. Meanwhile, the fixed end of the caster is arranged into a circular arc groove matched with the circular arc protrusion of the ground contact end, so that when the caster is in a folding state, the circular arc groove of the fixed end of the caster and the circular arc protrusion of the ground contact end of the adjacent caster are matched and folded, and the whole body is circular and matched with the auxiliary fixed hub in size.

The auxiliary fixing hub and the power wheel are matched in shape and size, and the setting position and the number of the hub connecting bolt holes in the auxiliary fixing hub are matched with the model of the original vehicle hub on which the auxiliary device is required to be installed. The bolt hole openings corresponding to the caster and the auxiliary fixing hub are respectively provided with a concave part and a convex part which are matched with each other and have the thickness of 1-5 mm, so that the caster and the bolt hole of the auxiliary fixing hub are correspondingly clamped in place and screwed into the locking bolt group for fixing.

Supplementary fixed wheel hub and caster can set up to the integral type foundry goods, and caster direct fixation is the expansion state, can use after the direct mount when the vehicle is absorbed into the predicament.

When the vehicle directly adopts the wheel hub provided with the bolt hole for fixing the wheel foot, the wheel foot can be directly fixed on the wheel hub of the vehicle through the locking bolt group without adopting an auxiliary fixing wheel hub.

The invention has the beneficial effects that: the auxiliary device for escaping the vehicle is additionally arranged on the hub of the power wheel of the vehicle, when passing through a predicted trapped road section, the wheel feet can be arranged in a unfolding state in advance, or when the wheel feet are stuck in slipping and deep sinking and trapped due to various obstacles, the wheel feet are arranged in the unfolding state, the wheel feet rotate forwards or back up along with the forward driving of the wheel, the support legs and the support lugs arranged on the wheel feet of the auxiliary device intermittently contact the ground, the forward or back-up action is the same as walking and stepping, the automobile is helped to escape without external force, and the escaping can be completed only by self power. The invention effectively improves the ability of the vehicle to get rid of the trouble by depending on the power of the vehicle and saves the related cost generated by waiting and rescuing. The sizes of all parts of the invention can be adjusted adaptively according to the type, the weight, the size of wheels and the working road condition of the vehicle, but the structure and the principle are not changed. The invention has the advantages of few parts, simple structure and lower requirement on processing precision, so the invention is convenient to manufacture and install and greatly saves the use cost. And the design scheme of the invention has both beauty and practicability, and is beneficial to popularization and application of products.
