The purpose of this utility model is to provide a kind of car/heavy duty tire high speed/durability test machine, it adopts the Barrate type structure, as simulated roadway, and detected tyre imposed given load with rotary drum, in the hope of important quality parameters such as the critical velocity that records tire and endurances.

The technical solution of the utility model: a kind of car/heavy duty tire high speed/durability test machine, it is characterized in that it is made of support, frame, propulsion system, drum device, lever arm device, high-voltage oil cylinder device, said drum device comprises drum axle and drum, the drum axle is according to the center of Bearing Installation in frame, drum axle head head is equipped with drum, and the external part of drum axle is equipped with belt pulley and is connected with the output terminal belt wheel of propulsion system according to driving belt; Said lever arm device comprises slideway, lever arm body and trial target spindle nose, slideway is loaded between the gap of drum back and frame, lever arm body one end is tabular, be inserted in the slideway, the two is sliding connection according to linear bearing, the other end fixedly is equipped with a web joint perpendicular to the arm body, the other end of web joint connects the sensor output terminal in the high-voltage oil cylinder device, the input end of sensor is connected with the output terminal of high-voltage oil cylinder, vertical installation test product spindle nose on the lever arm plate, trial target tire and rotary drum were and compress tangent shape when trial target was loaded on this spindle nose.

The above-mentioned said rotary speed parameter that rotary drum is provided and supply with trial target pressure high-voltage oil cylinder pressure parameter all routinely technology send in the switch board by computing machine by electric impulse signal and voltage signal and control adjustment.

The above-mentioned said rotary drum that places frame to rouse on the axle head head can be established symmetrical two, also can establish one-sided one.

The above-mentioned said lever arm plate that the trial target spindle nose is housed can be divided into the rotary drum both sides and be a drum two station forms and also can be two drums, four station forms.

Using method of the present utility model: after installing the trial target tire on each station spindle nose of testing machine, with the simulated roadway of rotary drum as activity, provide given load by the high-voltage oil cylinder device to tire, provide travel speed by propulsion system by rotary drum, above-mentioned parameter can increase step by step, it is destroyed to tire to turn round, and measures the critical load and the critical velocity of tire thus.

Superiority of the present utility model is: 1, be skillfully constructed, a machine dual-purpose can carry out the speed and the endurancing of tire simultaneously; When 2, this machine was a drum two stations or two drums, four stations, its station also can be tested simultaneously and can carry out separately, and was easy to use, high efficiency; 3, the complete machine serviceability meets relative national standards; 4, self-control is strong, and operation labour intensity is little, safe and reliable.

Further specify present technique below in conjunction with drawings and Examples.
