Abstract
The utility model relates to a tire technical field, concretely relates to novel notch cuttype tire tread wearing and tearing degree of depth sign, the echelonment sign is located tire tread's decorative pattern piece or the decorative pattern piece edge degree of wear for the mark tire. The utility model relates to a novel notch cuttype tire tread wearing and tearing degree of depth sign, this structure adopts the echelonment form to it is integrated in the decorative pattern global design. Through this kind of wearing and tearing sign, individual character pleasing to the eye more not only, the form of echelonment and the audio -visual wearing and tearing situation that has indicated tire more concrete more than tradition wearing and tearing mark in addition can also the certain degree increases the tire and grip the comprehensive security performance that improves the tire.
Description
Technical field
The utility model relates to tyre technology, is specifically related to a kind of tire protector mark.
Background technology
The Tread Pattern of Meridian Tyre wear limit of China's national Specification car is 1.6mm, and the Tread Pattern of Meridian Tyre wear limit of lorry, passenger vehicle is 2.0mm, and require stream in tire manufacturing plant must be obligatory on tire by standard configuration abrasion indicator.When tread wear is to the above-mentioned limit, namely abrasion indicator should show, to remind the timely changing of tire of chaufeur.
Current stream in tire manufacturing plant traditional method is the crown groove trench bottom at tire, along the boss arranging a high 1.6mm of tire circumference five equally divided positions.When tread wear is to during apart from channel bottom 1.6mm, the groove of this part just starts to disconnect, and thus occurs a crackle clearly.Thus remind the necessary changing of tire of chaufeur.
But tradition abrasion are labeled as primary structure, the limit abrasion operating mode of tire only can be indicated.
Utility model content
The utility model is a kind of Novel step-type tread wear deep identification, as supplementing of tradition abrasion mark, more specifically identify the abrasion situation of tire more intuitively, can also to a certain degree increase tire holding power, the comprehensive safety performance improving tire.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Novel step-type tread wear deep identification, and described stepped mark is positioned at the pattern block of tire protector or pattern block edge in order to mark the degree of wear of tire.
Preferably, described stepped mark is positioned at pattern block sharp corner.
Preferably, the ladder height of described stepped mark is arithmetic progression arrangement.
Preferably, the height of described stepped mark equals tire tread ditch depth.
Multilayer equal altitudes step is set according to tire tread ditch depth, with tire used, often wears away the tread mix of one deck step, represent the tyre surface wearing away corresponding height, when wear away only remaining one deck step time, represented or be about to abrasion to prescribed limit state.
The utility model is a kind of Novel step-type tread wear deep identification, and this structure adopts stepped form, and is integrated in decorative pattern unit design.By this kind of abrasion mark, not only individual character more attractive in appearance, and also stair-stepping form marks more specifically than tradition abrasion and has indicated the abrasion situation of tire intuitively, can also to a certain degree increase tire holding power, the comprehensive safety performance improving tire.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the utility model generalized section.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
A kind of Novel step-type tread wear deep identification, described stepped mark is positioned at the pattern block of tire protector in order to mark the degree of wear of tire.Described stepped mark is positioned at pattern block sharp corner.The ladder height of described stepped mark is arithmetic progression arrangement.The height of described stepped mark equals tire tread ditch depth.
Multilayer equal altitudes step is set according to tire tread ditch depth, with tire used, often wears away the tread mix of one deck step, represent the tyre surface wearing away corresponding height, when wear away only remaining one deck step time, represented or be about to abrasion to prescribed limit state.Such as groove total depth is 8mm, designs 4 layers of step, and every layer of shoulder height difference level is 2mm, therefore, along with the wearing and tearing in tire used, often wears away one deck step, represents the tread-rubber wearing away 2mm; When wearing away 2 layers of step, represent the tread-rubber wearing away 4mm; When only remaining last one deck step, representing and being about to abrasion to prescribed limit state.
