Abstract
The invention discloses a coaxial type hydraulic retarding braking device, which comprises a transmission shaft, a pulling fork, a positioning mechanism, a clutch assembly, an oil pump rotor, an oil pump casing and an oil pressure control system, wherein the oil pump rotor is born on the transmission shaft through a bearing, a clutch inner sleeve is born on the transmission shaft through a sliding spline in a matching way, a clutch outer sleeve is fixedly connected onto the oil pump rotor for realizing the clutching of the transmission shaft and the rotor, and the oil pump casing is connectedonto a machine frame through screw bolts. The coaxial type hydraulic retarding braking device has the advantages that the size is compact, the weight is light, the energy is saved, the reliability isrealized, and the service life is long. The braking device is convenient to install and refit, the braking force is not attenuated after long-time work, no power consumption is generated during no work, the safety factor is improved, the braking is mild and smooth, no collision is caused, and the coaxial type hydraulic retarding braking device is suitable for vehicle braking, is also suitable forhydraulic motor driving and can also be used for deep wells, deep seas, tool and substance hanging and conveying and the like.
Description
technical field [0001] The invention relates to a hydraulic retarder, in particular to a coaxial hydraulic retarder. Background technique [0002] With the rapid development of my country's economy and the improvement of road infrastructure conditions, the speed of vehicles is getting faster and faster, and there are more and more heavy vehicles. The number of accidents is on the rise year by year. [0003] On May 4, 2009, a major accident occurred in Yunnan Province of my country due to a truck brake failure. Three vehicles collided and one vehicle lost control and drove off the road, killing 14 people and injuring 50 others. The cause of the accident investigation: The truck driven by the perpetrator braked continuously on a 6-kilometer downhill road, which increased the wear time of the brake shoes and brake drum, resulting in an increase in the temperature of the brake drum, resulting in thermal decay, and eventually led to brake failure. In the past two years, the numb...
