A suspension energy feedback device of a mining wide-body dumper comprises a suspension cylinder, a generator and a hydraulic motor, the suspension cylinder comprises a cylinder body, a piston arranged in the cylinder body and a piston rod connected with the piston, and the piston divides the interior of the cylinder body into a rodless cavity and a rod cavity; the piston rod is of a hollow structure, one end of the piston rod is connected with the rodless cavity, the other end of the piston rod is connected with a first oil port of the hydraulic motor through a second one-way valve, and the rod cavity is connected with a second oil port of the hydraulic motor through a third one-way valve. The second one-way valve and the third one-way valve are arranged on the oil pipeline. Hydraulic oil and high-pressure inert gas are arranged in the suspension cylinder. During the compression stroke of the suspension cylinder, hydraulic oil flows to a rod cavity from the rodless cavity side through a first one-way valve in the suspension cylinder; when the suspension cylinder extends, hydraulic oil sequentially flows to the rodless cavity from the rod cavity side through the third one-way valve, the hydraulic motor and the second one-way valve, and the hydraulic motor rotates to drive the generator to generate electricity.
一种矿用宽体自卸车悬架馈能装置,包括悬挂缸、发电机和液压马达,悬挂缸包括缸体、设在缸体内的活塞和与活塞连接的活塞杆,活塞将缸体内分隔成无杆腔和有杆腔;活塞上设有连通无杆腔与有杆腔的第一单向阀,活塞杆为中空结构,活塞杆的一端与无杆腔连接,活塞杆的另一端通过第二单向阀与液压马达的第一油口连接,有杆腔通过第三单向阀与液压马达的第二油口连接,第二单向阀和第三单向阀设在油管路上,悬挂缸内设有液压油和高压惰性气体。悬挂缸压缩行程时,液压油从无杆腔侧经悬挂缸内第一单向阀流向有杆腔;悬挂缸伸长行程时,液压油从有杆腔侧依次第三单向阀、液压马达、第二单向阀流向无杆腔,液压马达旋转带动发电机发电。
