snow tires

Abstract

The invention discloses a tire for snowfields. The tire comprises a tire body, a tire side and a tire tread, wherein the tire tread is arranged on the tire body and contacts the ground; the tire tread consists of a plurality of tire shoulders which are divided by crossing a plurality of longitudinal grooves and a plurality of transverse grooves and have the same and different shapes; the widths of a plurality of transverse grooves are greater than those of a plurality of longitudinal grooves, so that the snow removal and drainage performance of vehicles can be improved, and the safety of the vehicles which run on roads in winter can be ensured; a plurality of tire shoulders are distributed symmetrically in a staggered mode by taking a center line in the peripheral direction of the tire body as reference; a plurality of fine grooves are also formed on a plurality of tire shoulders and can divide each tire shoulder into a plurality of tire shoulder subblocks which are connected with each other; and the tire shoulders which are close to the tire side in a plurality of tire shoulders are square pattern blocks, so that the grounding area is increased, the traction force is improved, and the stability of the running vehicles is improved.

Description

technical field [0001] The invention relates to the field of tires, in particular to a snow tire. Background technique [0002] The main functions of tires are to transmit driving force, change driving direction, buffer vibration and bear weight, etc., and the safety performance of tires depends to a large extent on its grip and stability. With the decrease of winter temperature and the increase of rain and snow, the situation of road surface icing occurs frequently. If you use ordinary summer tires or all-season tires, the gripping ability of ordinary tires will become smaller when the vehicle is driving on icy and snowy roads, especially on slippery ice surfaces, the adhesion coefficient of the tires will become very small , the most prone to dangerous situations such as skidding, so that the tires will not be able to function normally. Improper operation is also prone to accidents such as skidding, loss of control, and deep sinking, which seriously threaten the personal ...

Problems solved by technology

If you use ordinary summer tires or all-season tires, the gripping ability of ordinary tires will become smaller when the vehicle is driving on icy and snowy roads, especially on slippery ice surfaces, the adhesion coefficient of the tires will become very small , the most dangerous situation such as skidding is the most likely to occur, so that the function of the tires cannot be played normally. Improper operation is also prone to accidents such as skidding, loss of control, and deep sinking, which seriously threaten the personal safety of drivers and pedestrians.
