Description

TECHNICAL FIELD

[0001] The utility model relates to clutch test equipment technical field, concretely is a kind of clutch endurance test device and endurance test room. BACKGROUND

[0002] In the field of automobile manufacturing, as a key component of vehicle cooling system, the performance of clutch directly affects the temperature balance in the engine compartment of vehicle and driving safety. Therefore, the clutch must be subjected to strict durability test in the production process to ensure its reliable operation under various complex use conditions. Durability test usually involves simulating the working environment of clutch in actual use to evaluate its comprehensive performance changes under repeated engagement and periodic operation for a long time.

[0003] Most of the clutch durability test devices on the market currently adopt fixed structure design, and the most critical part is the rotational speed sensor used to detect the rotational speed of clutch. This kind of sensor is usually installed at a fixed position to monitor the rotational speed of clutch during the test process. However, this fixed sensor installation method has obvious defects:

[0004] 1. Limited detection range: Since the position of rotational speed sensor is not adjustable, once the size of clutch changes, the fixed sensor position may not be able to accurately detect the rotation of clutch. This means that the existing test device can only be used to detect clutches of specific size, and cannot adapt to products of different specifications, greatly limiting its application range.

[0005] 2. Poor adaptability: In actual application, the size of clutch may vary depending on the vehicle model. When testing clutches of different sizes, the sensor at fixed position often cannot meet the requirements, resulting in poor versatility of the test device.

[0006] To solve the above problems, the present application provides a clutch durability test device. UTILITY MODEL CONTENTS

[0009] The rotating speed detection assembly comprises a chassis, an aluminum type rod, a support fixed on the chassis, an adjusting disc fixed on the two supports, a vertical rod fixed on the chassis, a clamping block I connected on the vertical rod, an adjusting rod fixed on the aluminum type rod, a rotating speed sensor fixed on the top of the adjusting rod, and a clamping block II fixed on the adjusting rod, the clamping block I and the clamping block II are rotationally connected through a rotating shaft, an arc-shaped connecting groove is arranged on the adjusting disc, and connecting bolts are arranged on the two ends of the aluminum type rod and connected with the arc-shaped connecting groove.

[0010] Further, the support table is further provided with a bearing seat, and the rotating shaft is rotationally connected with the bearing seat.

[0011] Further, the output end of the rotating power device is connected with the rotating shaft through a shaft coupling.

[0012] Further, a support plate extends outward from the bottom of the support table, and a heavy load shock absorber is fixed to the bottom of the support plate.

[0013] Further, a fixing plate extends from one side of the chassis, and the fixing plate is fixedly connected with the support table through bolts.

[0014] Further, the rotating speed sensor is a light-receiving type photoelectric sensor, comprising a transmitting end and a receiving end, and the transmitting end and the receiving end are arranged on the adjusting rod on the two sides of the clutch.

[0015] Further, a rotating speed gear disc is fixed on the rotating shaft, and a main shaft sensor for detecting the rotating speed of the rotating shaft is arranged at the bottom of the rotating speed gear disc.

[0016] The application also provides a durability test chamber, which comprises a test chamber, a cold air device arranged on the bottom sidewall of the test chamber and used for blowing cold air into the test chamber, an air extraction device arranged on the top wall of the test chamber and used for extracting hot air in the test chamber, a temperature sensor arranged in the test chamber, and a clutch durability test device arranged in the test chamber.

[0020] 1. The detection range is improved: by arranging the adjustable rotating speed sensor, the device can be flexibly adjusted according to different sizes of clutches, so that the sensor is always in the best detection position. In this way, the test device is no longer limited to single-specification clutch testing, but can adapt to clutches of various sizes, greatly expanding the application range of the test device.

[0021] 2. Enhance test precision: The traditional fixed speed sensor position cannot be adjusted according to the specific situation of the clutch, which is easy to cause detection error.
