Problems solved by technology

However, in order to ensure the sealing performance of the steel ring of the "special tubeless rim", the steel plate of the main wall and the secondary wall must be welded in the whole circle, and it is required to be absolutely seamless. This is not only difficult to weld, but also time-consuming and costly. In addition, once the auxiliary wall steel plate is welded on the main wall steel plate at the bottom of the groove, if you want to adjust the tightness of the steel wire or replace the steel wire, you must disassemble the entire circle of auxiliary wall steel plate and then weld it on , it is a very difficult and troublesome thing

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and typical embodiments.

[0024] In Fig. 1 and Fig. 2, the tubeless rim A of the present invention consists of a steel rim 11, a hub C, and steel wire spokes D which are arranged between the steel rim 11 and the hub C and are arranged radially as a whole. The steel rim 11 The part drawn with a dotted line above is the tubeless tire B, which is characterized in that the steel ring 11 is composed of a steel ring main body 12 and a sealing material 13, wherein: the steel ring main body 12 is made of a hard metal material, and is arranged in the middle The groove 14 and the left and right flanges with flanges 16 on both sides of the groove 14 are formed. The groove 14 is composed of a ring-shaped groove bottom 14a and a ring-shaped left and right side walls 14b. 14a is provided with a limit installation hole 15 for steel spokes, and an outwardly convex curved portion 18 is p...

Abstract

The invention relates to a tubeless rim and manufacturing method thereof. The steel ring is overall sealed to form rim for assembing tubeless tire by setting a groove on a steel ring body, setting steel wire mounting hole on the bottom of the groove, welding a limited location snapping plate on the left and right side walls of the groove and filling and mounting with sealant material in the whole ring annular space between the left and right side walls and limited location snapping plate. Because of the action of limiting location and attaching, the sealant material is reliably lacated in the groove and the sealing is ensured, without coming off. The sealant material is set in manner of active assembling to allow disassembly as required. The invention has features of reasonable and simple structure and simple mountation and safe work, simple maintenace and low cost and provids convenience for installing the tubeless tire on the steel rim.

Description

technical field [0001] The invention relates to the technical field of wheel manufacturing for two-wheeled automatic vehicles mainly based on motorcycles, and is a pioneering technology for installing tubeless tires on spoke wire rims, specifically a tubeless rim and its Manufacturing method. Background technique [0002] Since the two-wheeled automatic car came out, the wheels used on the two-wheeled automatic car mainly contained two kinds of wire spoke wheels and molded wheels. Wire spoke wheels have a kind of classic beauty, plus it has good elasticity, light weight, and better stability than molded wheels when driving, so it is widely used in two-wheeled vehicles, even American cruisers , Off-road motorcycles are still using wire spoke wheels. [0003] But, because the steel rim of steel wire spoke wheel is provided with the limit installation hole that fixed steel wire spoke is used, can not guarantee sealing, so tireless tire can not be installed on it, can only ins...
