Description
Technical Field
The invention relates to a track tire, in particular to a riding wheel tire of a straddle type monorail vehicle.
Background
The straddle type monorail train is an urban rail traffic mode and has the advantages of low line construction cost, strong climbing capacity, low noise, high comfort level and the like. The bogie of the straddle type monorail vehicle is provided with three tires which are respectively a running wheel, a guide wheel and a stabilizing wheel, wherein the running wheel straddles over the track beam to bear the weight of the vehicle body, and the running wheel is directly contacted with the track beam to provide adhesive force for the vehicle to advance and brake. When the track beam is wet and slippery in rainy days, especially the steel box beam and the finger-shaped plates on the track beam are made of steel, the adhesion force between the running wheels and the steel box beam and between the running wheels and the finger-shaped plates is insufficient, the tires easily slip, the driving safety is affected, and the local abrasion of the tires is easily caused. Therefore, the tread wheel must improve the tire grip force when performing pattern design, so that the tire has good anti-skid performance and steering performance, the running safety of the tire and the comfort of passengers are ensured, and the occurrence of differential abrasion due to wet skid, idle running and other reasons is avoided.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a riding wheel tire of a straddle type monorail vehicle, which achieves the effect of enhancing the grip force of a tread, can ensure that the tire is not easy to slip under the wet skid condition, ensures the running safety, reduces the differential abrasion of the tire, and simultaneously has the effect of reducing the rolling resistance and noise of the tire.
The invention is realized by the following technical scheme, and is characterized in that:
a tread pattern of the tire is divided into a center rib, a first middle rib, a second middle rib, a third middle rib, a fourth middle rib, a first tire shoulder rib and a second tire shoulder rib by six circumferential linear grooves; the first middle rib and the second middle rib are respectively positioned at two sides of the central rib, the third middle rib and the fourth middle rib are respectively positioned at the outer sides of the first middle rib and the second middle rib, and the first tire shoulder rib and the second tire shoulder rib are respectively positioned at the outer sides of the third middle rib and the fourth middle rib; the central rib, the first middle rib, the second middle rib, the third middle rib, the fourth middle rib, the first tire shoulder rib and the second tire shoulder rib are all linear longitudinal ribs, so that the skid resistance of the tire during running is improved, and the rolling resistance of the tire is reduced; the width of the groove between the third middle rib and the first tire shoulder rib and the width of the groove between the fourth middle rib and the second tire shoulder rib are 1-2 mm narrower than the widths of the other four grooves; the center rib, the first middle rib, the second middle rib, the third middle rib and the fourth middle rib are all provided with inverted convex three-dimensional steel sheets; the inverted-convex three-dimensional steel sheets form an included angle of 5-20 degrees with a horizontal line clockwise or anticlockwise, the steel sheets on the adjacent ribs are arranged in parallel, the water film of a wet road surface is destroyed, the effect of obviously enhancing the ground grabbing force is achieved, and the good control performance of the tire is ensured; the first tire shoulder rib and the second tire shoulder rib are provided with imitation 'flat-pressing' steel sheets, the 'flat-pressing' is a Chinese character stroke, and the inclined strokes from top to bottom slightly have a wave fold when ending; the imitation flat-pressing steel sheet plays three roles: firstly, the grabbing force with the track beam is increased, particularly when the vehicle turns, the curved tail part of the steel sheet has viscous action with the track beam, so that the tire and the track beam are prevented from sliding friction, and abnormal abrasion of the tire is caused; secondly, the tail part of the steel sheet is not communicated with the outer side of the tire shoulder, so that the pumping of air in the pattern groove during tire running is reduced, and the tire running noise can be reduced; thirdly, the shoulder heat dissipation is facilitated, and the durability and the high-speed performance of the tire are improved.
As further preferable, the parts of the inverted-convex three-dimensional steel sheets close to the two sides of the pattern groove are shallower, so that the whole pattern ribs are firmly connected, and the phenomenon that the pattern blocks fall off or abnormal grinding is caused by dragging of the track beam to the steel sheet groove is prevented.
Preferably, the six circumferential linear grooves are provided with semicircular rectangular glue nail columns at the groove wall positions, two semicircular rectangular glue nail columns of adjacent groove walls are staggered to form a group of glue nail columns, and 20 groups of glue nail columns are uniformly distributed in the circumferential direction in each groove. The rubber nail column can destroy the cavity resonance effect caused by air flow in the linear pattern groove, thereby reducing the running noise of the tire. The rubber nail column can also support the groove wall to reduce tread deformation, reduce heat generation and rolling resistance, reduce differential grinding and improve mileage.
Preferably, the tread pattern has 88-90% of block saturation and the depth of the groove is 10+/-1 mm, so that the gripping property, drainage property and handling property of the tire are ensured, and meanwhile, the better driving mileage is ensured, and the optimal durability is obtained.
Due to the adoption of the tread pattern structural scheme, the running wheel of the straddle type monorail vehicle has excellent ground grabbing performance and control performance on the track beam, is not easy to slip under the wet sliding condition, reduces the local abnormal abrasion of the tire, ensures the running safety, and simultaneously effectively reduces the running noise and the rolling resistance of the tire.
