Concealed wheel slot safety wheel

Technical field

The present invention relates to a method of manufacturing a hub, and more particularly to a safety hub for a vacuum tire wheel having a concealed wheel groove.

Back recording technology

Car tires, which are the most frequently used and most vulnerable parts of automobiles, threaten the safety of life and property of drivers and passengers. Tires are prone to puncture or severe pressure loss due to structural inherent weaknesses, manufacturing defects, improper maintenance, external impact or weather. When this happens, the tire's tripping resistance is extremely reduced. The tire will be detached from the hub due to the friction with the ground, and will be drawn into the groove of the rim or fly out of the hub. After the tire loses the supporting force, the metal wheel directly contacts the ground. At this time, the wheel loses the normal driving force, braking force, steering force and other functions to the ground, causing the vehicle to "avalanche" out of control, resulting in serious traffic accidents. Summary of the invention

The present invention provides a safety hub with a concealed wheel groove design. When the lock is locked, the wheel groove can be hidden so that the lost-pressure tire does not get caught in the bottom of the groove or come out, and the under-pressure of the vehicle is used to firmly set the internal concave-convex gear of the hub to "bite" the tire with the wire-bound bead. In this way, even in the absence of air pressure, the tire can be synchronized with the wheel hub, and the rubber pad is formed by the thickness of the tire itself, and the wheel is transmitted to the ground to transmit normal functions such as traction force, braking force, steering force, etc., to ensure that the tire vehicle does not lose control. The wheel groove is exposed when unlocking, and the structure of the hub is the same as the traditional design, which does not affect the normal disassembly and assembly of the tire. The invention is convenient and reliable to use, does not affect the structure and performance of the tire and the hub, and is suitable for mass production vehicles, and is widely used for promotion.

The invention mainly comprises a sliding ring lock which can hide the wheel groove, and an adjusting device corresponding to the valve hole.

The sliding ring lock surface is made of metal with a ring-shaped metal ring with relatively high strength and friction resistance. The inside of the ring-shaped metal ring is a pressure-resistant gasket made of a temperature-resistant material with good load bearing capacity, which provides sufficient for the sliding ring lock. Supporting power.

One end of the slide ring lock is provided with a plurality of positioning sliders, and the sliders form a plurality of concave and convex slide rails with the groove slides on the corresponding hub. In this way, the sliding ring lock can slide left and right on the rim, but can prevent the axial rotation of the sliding ring lock.

The other end of the sliding ring lock is provided with a plurality of positioning rods corresponding to the positioning holes provided on the hub. When the sliding ring lock is locked, the positioning rod is inserted into the positioning hole to prevent the axial rotation of the sliding ring lock.

The inside of the sliding ring lock is provided with a locking device, the traction wire is tightened when the sliding ring is locked, and the brake friction plate holds the wheel hub. This ensures that the sliding ring lock can lock the hub without moving left and right when locked, and also increases the axial friction.

The above measures effectively ensure the reliability of the sliding ring lock when locking, which not only ensures the normal cooperation of the sliding ring lock and the hub without abnormal noise, and also ensures the axial traction force when the tire is rubbed against the wheel hub after the tire is broken. , braking force and steering force will not cause the sliding ring lock to be loose or damaged. The adjusting device is installed in the hidden wheel groove to connect the sliding ring lock to adjust the position of the sliding ring lock and expose the hidden wheel hub.

The adjustment device can use mechanical transmission, electric, pneumatic or hydraulic to complete the position of the transmission to adjust the sliding ring lock. The adjusting device switch corresponds to the valve hole, so that the locking and unlocking can be completed by inserting the key through the valve hole without turning the tire.

Figure 1 is a view of the unlocked state of the present invention. A sliding ring lock 35 is provided in the middle of the rim, and a plurality of positioning sliders 22 are disposed at one end of the sliding ring lock 35. The sliders form a plurality of concave and convex sliding rails 20 with the groove sliding passages 21 on the corresponding hubs. . Thus, the slide lock 35 can slide left and right on the rim and restrict the slide lock 35 from rotating axially.

The positioning slider 22 may be stamped on the annular eyelet 36 or may be attached to the inside. The groove chute 21 is completed when the hub is cast or machined.

The other end of the sliding ring lock 35 is provided with a plurality of positioning rods 38 corresponding to the positioning holes 39 provided on the hub. When the sliding ring lock 35 is locked, the positioning rod 38 is inserted into the positioning hole 39, and the axial direction of the sliding ring lock 35 can be restricted. Turn. The adjusting device 25 is disposed in the concealed wheel groove 18 corresponding to the valve hole 19 for driving the sliding ring lock 35 to move the position to complete the locking and unlocking.

When the slide ring lock 35 of the present invention is retracted to the left as shown in Fig. 1, the concealed wheel groove 18 is exposed, and the safety hub is now unlocked. In this way, the bead 11 can be caught in the concealed wheel groove 18 in the case of opening the tire, so that the bead 11 can be turned over the rim 15 to facilitate the disassembly and assembly of the tire. The two side bead 11 under the action of air pressure during inflation can be inserted over the peak 17 into the bead seat 16.
