And extension rods can be additionally arranged on the wheels on the two sides to form winches on the two sides, so that the escape effect is better.

Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle accessories, and in particular relates to a wheel screw winch used for escaping a vehicle wheel from slipping, and can be applied to self-rescue and rescue of vehicles in outdoor off-road under adverse road conditions. Background Art

[0002] At present, when a vehicle is stuck in a bad road condition, or the wheels slip, the vehicle can only be rescued by towing with a special winch or other vehicle winch. Installing a winch on the vehicle increases the weight and cost of the vehicle. Summary of the invention

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present utility model is to provide a wheel screw winch for vehicles with wheel slips to get out of trouble, which is easy to manufacture, low in cost and easy to use. It can help vehicles get out of trouble and rescue themselves or other vehicles without increasing the weight of the vehicle and at extremely low cost.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A wheel screw winch for escaping a vehicle wheel slip, comprising a wheel hub (1), characterized in that a fixing nut (3) of the wheel hub (1) is provided with a connecting thread, and the connecting thread is connected to an extension rod (2).

[0006] The fixing nut (3) is composed of a screw rod (3-1) and an end head, wherein the end head is provided with a countersunk hole B (3-3) or a protrusion B (3-2), the countersunk hole B (3-3) is provided with an internal thread, and the protrusion B (3-2) is provided with an external thread.

[0007] The extension rod (2) is composed of a rod (2-1) and an end, the end is provided with a countersunk hole A (2-2) or a protrusion A (2-3), the countersunk hole A (2-2) is provided with an internal thread, and the protrusion A (2-3) is provided with an external thread.

[0008] The number of the extension rods (2) is greater than or equal to 3.

[0009] The number of the fixing nuts (3) is the same as the number of the hub screw holes.

[0010] The wheel screw winch, in addition to the above-mentioned method of adding an extension rod, can also adopt a method of integrating the extension rod with the wheel hub fixing bolt. When in use, the wheel hub fixing bolt with the extension rod can be replaced with the ordinary wheel hub fixing bolt of the vehicle.

[0011] The beneficial effects of the utility model are:

[0012] Most vehicles do not have a dedicated winch, and installing a winch will increase the weight of the vehicle and increase costs. When a vehicle using this patent is stuck in a wheel slipping situation, an extension rod is screwed onto the head of the wheel fixing bolt or the wheel fixing bolt is replaced with a fixing bolt with an extension rod. Several extension rods form a winch that can rotate with the wheel. One end of the traction rope is fixed with an anchor point, and the other end is wrapped around the winch composed of the extension rods. When the wheel rotates, the traction rope is tightened to drive the vehicle to move. At the same time, the slipping wheel is pulled by the traction rope and no longer slips. The wheel on the opposite side also obtains the transmission force of the engine (for vehicles without differential locks, if one wheel slips, the wheel on the other side will lose power). At this time, both wheels have transmission force, and under the action of the tension of the gradually tightened traction rope, the vehicle can get out of trouble. Extension rods can also be installed on both wheels at the same time to form a double-sided winch, which has a better effect of getting out of trouble. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with the accompanying drawings and working principles.

[0018] like Figure 1 , 2 As shown, a wheel screw winch for escaping a vehicle wheel slipping comprises a wheel hub (1), characterized in that a fixing nut (3) of the wheel hub (1) is provided with a connecting thread, and the connecting thread is connected to an extension rod (2).

[0019] like Figure 3 As shown, the fixing nut (3) is composed of a screw rod (3-1) and an end head, wherein the end head is provided with a countersunk hole B (3-3) or a protrusion B (3-2), the countersunk hole B (3-3) is provided with an internal thread, and the protrusion B (3-2) is provided with an external thread.

[0020] like Figure 4 As shown, the extension rod (2) is composed of a rod (2-1) and an end, the end is provided with a countersunk hole A (2-2) or a protrusion A (2-3), the countersunk hole A (2-2) is provided with an internal thread, and the protrusion A (2-3) is provided with an external thread.

[0021] The number of the extension rods (2) is greater than or equal to 3.

[0022] The number of the fixing nuts (3) is the same as the number of the hub screw holes.

[0023] When manufacturing the wheel fixing bolt, a thread for adding an extension rod can be processed on the head of the existing vehicle wheel fixing bolt, and the thread can be a protruding screw rod or a recessed nut. The wheel fixing bolt and the extension rod can also be made into a whole.

[0024] When in use, the vehicle wheel fixing bolt is screwed onto the extension rod or replaced with a wheel fixing bolt with an extension rod. Multiple extension rods form a wheel winch.

[0025] The working principle of the utility model is:

[0026] Traction effect:

[0027] 1. When using, fix one end of the traction rope with an anchor point, and wrap the other end around the winch composed of extension rods. When the wheels rotate, the traction rope tightens and drives the vehicle to move. The vehicle can then get out of trouble. You can also install extension rods on both sides of the wheels at the same time to form a double-sided winch, which will have a better effect of getting out of trouble.

[0028] 2. Make the wheel on the opposite side of the slipping wheel obtain transmission force:

[0029] Since the slipping wheel is pulled by the traction rope and no longer slips, the wheel on the opposite side also obtains the engine transmission force (for vehicles without differential locks, if one wheel slips, the wheel on the other side will lose power). At this time, both wheels have transmission force.

[0030] When the vehicle is stuck in a wheel slipping situation, screw the extension rod onto the wheel fixing bolt head or replace the wheel fixing bolt with a fixing bolt with an extension rod. Several extension rods form a winch that can rotate with the wheel. One end of the traction rope is fixed with an anchor point, and the other end is wrapped around the winch composed of the extension rods. The wheel rotates, and the traction rope is tightened to drive the vehicle to move. At the same time, the slipping wheel is pulled by the traction rope and no longer slips. The wheel on the opposite side also obtains the engine transmission force (for vehicles without differential locks, if one wheel slips, the other wheel will lose power). At this time, both wheels have transmission force, and under the tension of the gradually tightened traction rope, the vehicle can get out of trouble. Extension rods can also be installed on both wheels at the same time to form a double-sided winch, which has a better effect of getting out of trouble. The extension screw is usually not installed on the vehicle wheel and has no effect on the normal driving of the vehicle.
