Description

Wheel rim transmission type vehicle escaping external member

1. Belongs to the technical field

The technical scheme of the invention is a mechanical product, which is used for improving the passing ability of a front-drive SUV and a car to the complex road conditions, the device is prepared on the car, and three corresponding modes of snow antiskid, wet and slippery slope traction and mud pit escaping are flexibly provided for two-drive SUVs and cars with poor passing ability by adopting a method of adjusting the combination mode of the structural kit according to different rescue requirements, so that the passing ability of the car is effectively improved. The device is also suitable for four-wheel drive vehicles to get rid of difficulties.

2. Background of the invention

At present, in the aspect of self-rescue of a skid-resistant vehicle or a trapped vehicle, three methods of additionally installing an anti-skid chain, an electric winch and a bolt fixed hub winch are mainly adopted, wherein the two methods can only be used on a cross-country vehicle with a firm chassis.

The electric winch is too heavy and rarely used at ordinary times, so that the electric winch becomes a encumbrance when being installed on a vehicle for a long time, is too complicated when being installed on site when being used urgently, and the vehicle body and the suspension mechanism must bear a large load when being used;

the hub winch is also a escaping scheme only used for hard off-road vehicles, and is invented by Americans at first. However, for a front-drive SUV or a car with a small bolt spacing, the bolt is easily deformed or even broken due to overlarge moment caused by radial tension and double loads of shear stress. In addition, in order to reach pleasing to the eye and firm purpose, the wheel hub fixing bolt of various small vehicles is whole to be the design of hiding, and the nut falls deep in the spoke plane, and the spoke outside molding is various to be uneven, and these situations make the fixed capstan winch of plus bolt can't bear too big external force more. Moreover, the difference between the winding diameter of the hub and the outer edge of the tire is too large, the difference between the translation linear speeds of the vehicle provided by the hub and the tire is also large, when the vehicle is separated from a mud pit and the tire can move forwards by means of self friction force, the dragging rope is immediately loosened, disorder occurs and even is separated from the winding drum, and if the tire presses on wet and slippery ground again, the traction rope can be instantly tightened and generates a very large impact load, so that the vehicle is damaged. Therefore, the winch type wheel winch can only be used for short-distance towing and is not suitable for long-distance towing. The method can be effective in the occasions where the vehicle needs to be dragged out of the mud pit. The effect of smooth use cannot be achieved for road conditions such as hard, wet and slippery ice and snow ramps, meadow slopes and the like which need to be towed for a long distance.

In the aspect of dealing with the vehicle is stranded, besides the two devices, the antiskid chain is also frequently used on a wet road surface by people, the antiskid chain can relieve the skidding problem of the vehicle to a certain extent, but when the road surface has a steep gradient or a tire is trapped in a mud pit, the limited antiskid effect can be lost.

Therefore, in the aspect of improving the vehicle passing capacity, the existing various self-rescue equipment has great limitations in the aspects of practicability and effectiveness. Then can not invent a new device again, make it can not only be applicable to the vehicle of various different models widely, but also can provide the scheme of saving oneself that deals with various road conditions in a flexible way?

3. Summary of the invention

As people know, when the vehicles run on urban and rural roads, the vehicles run on numerous economically applicable small-displacement front-wheel drive SUVs and popular cars which are comfortable to ride, are popular among people due to the outstanding advantages of light weight and fuel saving, and are vehicles with the highest use rate and the highest popularization rate when people go out. But their poor ability to pass through complex road conditions is an inherent shortboard and pain point. When the road conditions are good, the maneuverability, the comfort and the economy of most two-wheel-drive vehicles can comprehensively surpass those of 4WD off-road vehicles. However, \36834Thedriver and passengers occasionally encounter a slippery mud pit in the road in thousand miles and need to seek external assistance, and if the driver and the passengers have no recourse, the drivers and the passengers can only watch the road exclamation. The front-wheel drive vehicle is poor in passing ability and lacks of self-rescue means and methods, so that when a driver goes out in rainy and snowy days, the driver has a worry, and all self-rescue escaping equipment on the market at present is only used for off-road vehicles. Therefore, the invention aims to solve the problem that a practical self-rescue device, namely a rim transmission type vehicle escaping kit, is specially created for the front-wheel drive vehicle.

4. Technical problem to be solved

Aiming at the defect of narrow application range of the existing escaping equipment, a set of self-rescue scheme which can be generally applicable to various passenger vehicles, is convenient to carry and install and can provide effective self-rescue when the vehicles are trapped is provided, and the scheme is the self-rescue scheme of the rim transmission type vehicle escaping kit. The main components of the external member are composed of a binding type transmission ring, an outer retainer ring, a winch supporting ring, a rope guiding ring and a binding rope, the combination of components can be flexibly changed according to different self-rescue requirements, and various rescue modes with different effects are provided, so that the external member is suitable for different rescue occasions.

5. Technical scheme

The main characteristics of the rim binding type vehicle escaping structure suite are as follows:

firstly, the external member uses the steel cable to bind, adds the wooden wedge fastening mode, fixes the drive ring firmly on rim and tire. When other members are not added, the binding steel ropes can play a role of skid resistance, and the firmness degree of the binding steel ropes exceeds that of other used skid chains. The antiskid performance can be improved when the vehicle runs at low speed on a wet road surface. The structural key points of the component are as follows: the rope running groove and the rope threading hole arranged on the transmission ring must enable the binding rope to avoid an air nozzle gear and a brake cylinder on the rim, and the arrangement of the groove and the hole must be in proper position and accurate size. The figures show the shape, configuration and combination of components of the kit that is practical for each model of vehicle, but the specific dimensions are configured to be determined in accordance with the specific requirements of the particular model of vehicle. The proposal is not applicable to the cars with the individual gaps between the brake cylinder and the wheel rim smaller than the distance between the binding ropes;

secondly, when the vehicle is trapped in a wet and slippery mud pit and is trapped, an outer check ring can be conveniently and rapidly arranged on the outer side of the transmission ring, then a steel rope with the diameter of 8mm for dragging is wound on the small winding drum, the steel rope for dragging is fixed in the front of the small winding drum, and the wheel bound with the transmission ring can be changed into a small winch. Because the diameter of the small winding drum is only 1/2 of the outer edge of the wheel, under the condition that the output torque of the vehicle engine is unchanged, the traction force provided by the steel rope is twice of the traction force of the original wheel, the vehicle can be easily pulled out of a mud pit, in addition, the tensile strength of the left steel rope and the right steel rope with the diameter of 8mm is greater than 2000 pounds, and the provided tension force is more than enough. Moreover, the steel rope tension action point of the scheme is between the rim, the tire and the ground, the conditions of a vehicle suspension mechanism and a vehicle body structure are not different from those of a common vehicle, the tension brought by the traction rope cannot influence the suspension and the vehicle body, and the special effect only achieved by the rescue scheme is achieved. For vehicles trapped in mud pits, self power is applied, and the vehicle can get rid of difficulties and save self in a dragging mode, which is the most effective method. The design point is that the diameter of the transmission ring reel depends on the ground clearance of the lower edge of the reel, the height is not more than 200mm for the front-drive SUV and not more than 150mm for the car, and therefore the friction between a steel rope and a car body when a front wheel needs to dial a small amount of direction is avoided.

And thirdly, in rainy and snowy days, when the vehicle runs into a wet and slippery steep slope and needs to climb, or when the vehicle runs on a wet and slippery meadow broken surface and needs to climb, the vehicle slips due to the fact that the adhesion coefficient between the tire and the ground is too low, which is a road trouble of another form, and the two aforementioned methods cannot achieve the effect of smooth response. At the moment, the winch outer retainer ring screw is loosened, the winch supporting ring and the rope guiding ring matched with the winch supporting ring are embedded into the winding drum, the outer retainer ring screw is screwed, and the small winch is the body-changing winch mechanism and is used for achieving long-distance traction. The use method comprises the steps of leading the traction rope into the traction rope guide ring by abutting against the outer edge rubber roll at the lower part of the rope guide ring, winding the traction rope by the rope guide ring and the outer side of the rope pulling rubber roll for two circles through the winch, pulling out the tail rope from the inner side of the rope guide ring to the rear side, piling and adding a rubber rib at the rear part of the vehicle to fix the traction rope, or slightly fastening the tail rope by using human power, and fixing the traction rope at the front end for traction climbing. In this mode, the diameter of the winch is slightly smaller than the outer diameter of the tire, the two winches provide very close linear speed, and the towed vehicle runs smoothly. By the implementation, the aim can be smoothly achieved even if the traction distance is hundreds of meters away. When using this kind of mode, the haulage rope has played the effect similar to tank track, has effectively overcome the difficult problem that the wheel skidded, has also avoided under the hoist mode, because of pulling the problem that the distance overlength causes the rope that needs the winding to exceed the reel and hold the limit and can't continue to pull. The design point here is; the traction rope entering the winch is controlled by a rope pulling rubber roll arranged on the rope guide ring, and the rope entering and exiting positions are respectively arranged at two ends of the winch, so that the phenomena of rope pressing and rope releasing can be prevented. The diameter of a rope inlet side winding drum of the supporting ring winch is gradually reduced to a rope outlet side in an excessive mode, so that the traction rope can automatically move axially in the operation process, the tail rope is continuously released backwards, and the smooth operation of the traction mechanism is ensured. A groove and a shape edge structure which are mutually matched are arranged between the winch supporting ring and the transmission ring and are combined in a mortise and tenon mode, so that the power can be transmitted to the supporting ring;

and the rope guide ring consists of a steel ring provided with a rolling rubber roller, fifteen polyurethane rubber rollers and a sled pulled and rotated. The small rubber roller arranged on the steel ring can play the roles of rolling the steel ring, guiding the steel rope and preventing the rope from being separated and pressed, and the sled is pulled to rotate to prevent the rope guide ring from rotating along with the wheel under the abnormal condition. The rope guiding ring has a simple structure and ingenious design and is an important component for ensuring the smooth operation of the whole mechanism in a winch mode.

5. Advantageous effects

The anti-skidding and escaping scheme can be flexibly provided for various small-sized passenger vehicles according to different application scenes, the limitation of the existing self-rescue equipment is overcome, the worries of the low-displacement economical vehicles which can only be used under the good road condition in the past when going out are relieved, drivers and passengers can take a wider rural area and country, the driver and passengers can easily go out, and the driver and passengers can walk even if riding alone.
