Abstract

The invention discloses a slide valve element type balance valve treadmill drive control system. The slide valve element type balance valve treadmill drive control system comprises a brushless directcurrent motor, a minitype hydraulic pump, a hydraulic motor, an oil tank, a slide valve balance valve and a controller. The brushless direct current motor drives the minitype hydraulic pump to providepressure oil for the system. An oil inlet in the bottom of the slide valve type balance valve is connected with an oil outlet of the minitype hydraulic pump. An oil return opening in the top of the balance valve is connected with an oil outlet of the hydraulic motor. An oil channel in the lower portion of the balance valve is connected with an oil inlet of the motor, and an oil channel in the upper portion of the balance valve is connected with the oil tank. The brushless direct current motor can adjust the flow of the system by adjusting the rotating speed. The controller is in charge of controlling the system to execute actions according to set actions. The slide valve element type balance valve treadmill drive control system is simple in structure, low in cost, high in integration degree, low in noise, good in reliability and not sensitive to the temperature and the cleanliness of the oil, heat dissipation is convenient, the accuracy and the stability of treadmill speed control andthe safety of the system can be effectively guaranteed, and the slide valve element type balance valve treadmill drive control system can reliably run for a long time.

Description

technical field [0001] The invention belongs to the field of fitness equipment and hydraulic control systems, and relates to a sliding valve spool type balance valve treadmill drive control system suitable for commercial or household treadmills. Background technique [0002] Treadmill is a very popular fitness equipment, fast running or jogging has become a very popular way of fitness. Along with the more and more popular of this kind of fitness mode, also more and more higher to the performance requirement of treadmill itself. As far as user experience is concerned, apart from various human-machine communication, physical condition monitoring, user interface and other additional functions, the most important indicator to measure the performance of the treadmill is the speed control performance of the treadmill, especially the speed control in the work project. accuracy and stability. Due to the working characteristics of the treadmill, the load generated by the running ac...
