Problems solved by technology

However, the vehicle does not always drive on a flat road in good weather, and the vehicle is prone to get stuck in driving difficulties due to changes in weather or road conditions
For example, the icy and snowy road surface caused by rain, snow, freezing and other bad weather will make the tires of the vehicle slip and easily cause the vehicle to lose control; when encountering complex road conditions such as muddy or various obstacles on the road surface, especially when the engineering operation vehicle is in the engineering operation process, Very prone to tire slipping, deep sinking or obstacles stuck tires unable to climb over obstacles
[0003] At present, there are two ways to solve the above-mentioned trapped problem of vehicles: one ...

Embodiment 1

[0021] According to attached figure 1 ~ attached image 3 , the wheel hub auxiliary device for vehicle escape in this embodiment is provided with two casters with the same structure, shape and size, which are respectively the first caster 3 and the second caster 4, and the two casters are symmetrically arranged on the auxiliary fixed hub 2 outer surfaces. The first caster 3 and the second caster 4 are respectively provided with fixed pin shaft holes, and the first caster 3 and the second caster are connected by the first fixed pin shaft 9 and the second fixed pin shaft 10 respectively. 4 is connected with the auxiliary fixed wheel hub 2, and can rotate around the fixed pin shaft respectively until contacting with another caster. When the two casters are in the folded state, the outer sides of the two casters are rounded after being folded, matching the size of the auxiliary fixed hub 2 .

[0022] The outer side of the first wheel foot 3 is in the shape of a semicircle, wher...

Embodiment 2

[0032] In this embodiment, the first caster 3 and the second caster 4 are independent components, and when work is required, they are directly symmetrically fixed to the auxiliary fixed hub 2 by the bolts in the corresponding first locking bolt group 11 and the second locking bolt group 12 The outer surface is unfolded, and it is ensured that each caster is fixed with 3 or more bolts, and at least 3 bolts used for fixing on each caster are not on the same straight line. After the work is finished, all the bolts in the locking bolt group are removed, and then the two wheel casters can be taken off.

[0033] Others are the same as embodiment 1.

Embodiment 3

[0035] In this embodiment, the auxiliary fixed hub 2 and the two casters are set as one-piece castings, and the two casters are directly in the unfolded state. When sleepy, the auxiliary fixed hub 2 is connected and fixed with the hub of the wheel 1 and can directly enter the working state. The advantage of this embodiment is that the auxiliary fixed wheel hub 2 and the two wheels are in a fixed connection state, and there is no need to consider the shape of the wheels after being folded, so that the two wheels can be set to a larger span, but the disadvantage is that in normal driving The auxiliary device must be removed to avoid affecting the vehicle's driving stability and driving experience.

[0036] Others are the same as embodiment 1.

Abstract

The invention provides a hub assisting device for saving a trapped vehicle. The hub assisting device comprises a fixing assisting hub and a caster arranged on the outer surface of the fixing assistinghub and is characterized in that one or more than one caster is arranged; when the caster is in an unfolded state, one end of the caster is a fixed end and fixed to the outer surface of the fixing assisting hub through a locking bolt group, and the other end is a ground contact end extending out of the outer surface of a wheel; the ground contact end of the caster is arranged into a support leg of an arc-shaped projection, and a support projection is further arranged at the inner side of the support leg and forms an included angle with the support leg, so that the ground contact end of the caster is herringbone; a plurality of bolt holes used for fitting the locking bolt group to fix the caster are arranged in the fixing assisting hub; and the fixing assisting hub is further provided witha plurality of through holes, namely hub connecting bolt holes, for the connection of the hub of the wheel, and the hub connecting bolt holes are 5mm to 2000mm in length. The hub assisting device caneffectively improve the capability of the vehicle on leaving a trapped position by self power.

Description

technical field [0001] The invention relates to a mechanical auxiliary device in the technical field of auto parts, and in particular discloses a wheel hub auxiliary device for vehicle escape. Background technique [0002] Vehicles have become the means of transportation commonly used in people's daily life and the necessary tools for various engineering operations. However, vehicles do not always drive on flat roads in good weather, and vehicles are prone to get stuck in driving difficulties due to changes in weather or road conditions. For example, the icy and snowy road surface caused by rain, snow, freezing and other bad weather will make the tires of the vehicle slip and easily cause the vehicle to lose control; when encountering complex road conditions such as muddy or various obstacles on the road surface, especially when the engineering operation vehicle is in the engineering operation process, It is very easy for the tire to slip, sink deep or get stuck in an obsta...
