Wheel slip control device

Abstract

This application relates to the field of anti-skid technology for motorcycle and electric bicycle wheels. According to the wheel anti-skid device of this application, the device can be electrically deployed and closed. When the wheel slips, a control switch drives a motor to actuate a screw, pushing down and extending an arc-shaped anti-skid device. The concave and convex teeth of the arc-shaped anti-skid part slightly protrude from the tire to increase the grip between the wheel and the road surface, preventing wheel slippage. When exiting a slippery road surface, the motor can be controlled to drive the screw to actuate the annular limit ring upwards, retracting the arc-shaped anti-skid part into a closed state. The diameter of the wheel anti-skid device is similar to that of the wheel hub, allowing the wheel to remain assembled for extended periods without disassembly for normal driving. In summary, this avoids problems such as brake slippage on icy or muddy roads, wheel spin during start-up, and loss of balance leading to falls and inability to ride, thus providing a safer and more convenient way to ride existing motorcycles and electric bicycles.

Description

Technical Field

[0001] A wheel anti-skid device Background Technology

[0002] To prevent motorcycles and electric scooters from slipping on icy, snowy, or muddy roads, especially on uphill sections where the surface is icy, motorcycles and electric scooters are likely to lose traction, skid, and fall, making them unable to ride. Currently, there are no effective anti-skid devices available on the market for motorcycles and electric scooters. Summary of the Invention

[0003] The purpose of this application is to provide a wheel anti-skid device, which includes a lifting limit ring; a lifting device fixing shell; a lifting limit switch; a speed conversion gear; a set screw fixing bearing; a motor; a lifting set screw; a lifting limit switch; a set screw pushing part; an anti-skid device carrying disc; a special-shaped support frame; a wheel anti-skid device and wheel hub fixing screw; a bearing limit bracket; an arc-shaped anti-skid part; a spring; a bearing; a return spring; a shell and anti-skid device carrying disc fixing screw; a special-shaped support frame and arc-shaped anti-skid part fixing shaft; and a bearing fixing shaft.

[0004] The anti-slip device is mounted on a disc on the wheel hub and rotates with the wheel. The anti-slip device includes a lifting limit ring, a lifting device fixing shell, a lifting limit switch, a speed conversion gear, a set screw fixing bearing, a motor, a lifting set screw, and a lifting limit switch. It is fixed on the wheel axle and remains stationary. The motor drives the speed conversion gear to rotate the screw, which in turn drives the set screw to push the lifting limit ring. This pushes down the bearing and the irregular support frame, causing the arc-shaped anti-slip part to pop out. When the lifting limit switch touches the lifting limit ring, it shuts off the motor.

[0005] The lifting limit ring always remains in a downward position. When the wheel rotates and the irregular support bracket bearing is at the bottom, it is pushed out by the lifting limit ring, causing the arc-shaped anti-slip part to unfold downward. The concave and convex teeth of the arc-shaped anti-slip part protrude slightly from the tire to increase the grip between the wheel and the road surface and prevent the wheel from slipping. When driving on a hard road surface, the bearing limit bracket, spring, and bearing play a shock absorption role.

[0006] When driving off a wet and slippery road surface, the motor can be controlled to drive the lead screw to push the annular limit ring upward and retract it. The reset spring drives the irregular support frame to retract the arc-shaped anti-slip part to form a closed state. After the wheel anti-slip device is closed, the diameter size is similar to that of the wheel hub, and the wheel can be installed and driven normally for a long time.

[0014] The first aspect of this application provides a wheel anti-skid device, thereby solving the shortcomings of existing anti-skid devices and the problem of difficulty in riding a vehicle in icy or muddy conditions.

[0015] The following reference Figures 1 to 4 This application describes in detail some embodiments of the wheel anti-skid device. According to this application, an anti-skid wheel, such as... Figure 1 Figure 3 As shown, 100-Tire; 1002-Wheel hub; 1003-Brake disc; 300-Wheel fixing axle; 301-Wheel anti-skid device and wheel hub fixing screw; 200-Lifting limit ring; 2001-Lifting device fixing housing; 2002-Lifting limit switch; 2003-Speed ​​conversion gear; 2004-Setting screw fixing bearing; 2005-Motor; 2006-Lifting setting screw; 2007-Lifting limit switch; 2008-Setting screw Propulsion unit; 4001-Anti-slip device bearing disc; 4002-Irregularly shaped support frame; 4003-Wheel anti-slip device and hub fixing screw; 4004-Bearing limit bracket; 4005-Arc-shaped anti-slip part; 4006-Spring; 4007-Bearing; 4008-Return spring; 4009-Outer shell and anti-slip device bearing disc fixing screw; 4010-Irregularly shaped support frame and arc-shaped anti-slip part fixing shaft; 4011-Bearing fixing shaft.

[0016] Based on the above technical features, the beneficial effects of this application are as follows: When the road surface is slippery or muddy in icy or snowy weather, making it difficult to ride the vehicle, the power switch causes the 2005-motor to drive the 2003-speed conversion gear, which in turn causes the 2006-lifting jack screw to rotate and push the 2008-jack screw pusher to move the 200-lifting limit ring downwards. The 2002-lifting limit switch then touches the top of the 200-lifting limit ring and closes. The 2005-motor and 200-lifting limit ring remain in a downward position. When the wheel rotates, the 4002-irregular support frame and 4007-bearing, which are located below, are pushed out by the 200-lifting limit ring, causing the 4005-arc anti-slip part to pop out and unfold downwards. The concave and convex teeth of the 4005-arc anti-slip part protrude slightly from the tire to increase the grip between the wheel and the road surface and prevent the wheel from spinning, slipping, or skidding. When riding on a hard road surface, the 4006-spring, 4007-bearing, and 4004-bearing limit bracket play a shock-absorbing role.

[0017] When driving off a slippery road surface, the power switch can be used to activate the 2005-motor to drive the 2003-speed conversion gear, causing the 2006-lifting jack screw to rotate and push the 2008-jack screw pusher to move the 200-lifting limit ring upwards. The 2002-lifting limit switch will then contact the 2008-jack screw pusher to close, and the 2005-motor and 4008-reset spring will cause the 4002-irregular support frame to retract, forming a closed state with the 4005-arc anti-slip part. After the wheel anti-slip device is closed, its diameter is similar to that of the wheel hub, allowing the wheel to be installed and driven normally for a long time.

[0018] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the scope of the technology disclosed in this application, or make equivalent substitutions for some of the technical features.
