Abstract

The invention relates to a cooling wheel testing device. The cooling wheel testing device comprises a support, a frequency converter, a motor, couplers, bearings, a stepped shaft, a torque meter and wheels, wherein the frequency converter is fixedly mounted below the support; the motor and the torque meter are horizontally opposite to each other, fixedly mounted at the left end and the right end of the support respectively and located in the same axis; the stepped shaft is supported by the two bearings mounted on the support, the two ends of the stepped shaft are connected with an output shaft of the motor and an input shaft of the torque meter through the couplers respectively, and a cooling wheel is mounted on the small-diameter shaft section of the stepped shaft for testing; the wheels are fixedly mounted at the lower ends of the four corners of the support respectively, the support can be moved through the wheels, and meanwhile a locking structure is arranged on each wheel; a base of the support can be stretched to adapt to stepped shafts with different lengths. The cooling wheel testing device is reasonable in structural design, low in manufacturing cost and good in detection effect.

Description

technical field [0001] The invention relates to a cooling wheel test device, in particular to a device capable of measuring the temperature of the wheel surface and the temperature of the brake position of the cooling wheel under different speeds, temperatures and road conditions, and calculating the temperature of the brake position at various speeds. Test device for the extent of temperature reduction of the wheel surface. Background technique [0002] The development of the automobile industry has brought a lot of convenience and joy to people's travel. Unfortunately, traffic safety is always threatening people's property and life safety. In recent years, the tire blowout accidents of vehicles have increased suddenly. According to statistics, tire blowout accounts for more than 70% in traffic accidents on expressways. Car accidents caused by frequent tire blowouts have aroused people's vigilance and confusion. Why were tire blowouts rare in the past when the road condi...
