Two-piece type wheel hub used for non-pneumatic tire

Abstract

The invention provides a two-piece type wheel hub used for a non-pneumatic tire. The wheel hub includes a first wheel ring and a second wheel ring which are coaxially and relatively arranged, the second wheel ring and the first wheel ring both includes a wheel disk part and a wheel rim part, and each wheel disk part and the corresponding wheel rim part are formed into an integral structure; the non-pneumatic tire includes a supporting body, the contact surface of the wheel hub and the supporting body is provided with a thermal insulation strip, the radial outer side of the thermal insulation strip is connected with the supporting body, and the radial inner side of the wheel rim part is connected with the wheel rim part in a sleeving mode; the surface, making contact with the thermal insulation strip, of the wheel rim part is uniformly provided with helical teeth, an included angle is formed between each helical tooth and the axial line, and the surface, making contact with the wheel rim part, of the thermal insulation strip is provided with grooves cooperated with the helical teeth. According to the two-piece type wheel hub used for the non-pneumatic tire, the problems that the wheel hub installation of the non-pneumatic tire is difficult, the non-pneumatic tire is easily separated from the wheel hub due to local overheating and aging in the high speed running or emergency brake condition and the thickness of the non-pneumatic wheel hub part is large are solved, and the safety of tire is improved.

Description

technical field

[0001] The present application generally relates to the field of wheels, specifically to the field of tire hubs, and in particular to a two-piece hub for non-pneumatic tires. Background technique

[0002] At present, the wheel hubs suitable for non-pneumatic tires are all ordinary one-piece hub structures. For ordinary non-pneumatic tires and rims, on the one hand, it is difficult to install the rim, which is mainly reflected in the thickness of the non-pneumatic tire and rim. The bolts are connected to the rim, specifically, either the rim is directly formed with the non-pneumatic tire at one time, and the rim cannot be reused; or the excessive interference contact is used between the two, and the radial size of the rim is too large, which is easy to install. cause damage to the support.

[0003] On the other hand, during high-speed driving or emergency braking, tires are prone to local overheating and aging, slipping from the rim, etc., which poses a great...
