FIELD: transport. ^ SUBSTANCE: device 100 comprises damping system 10 retained in case 11 and provided with flexible element 12, and hydraulic damping device. Device 100 has also piston con rod 2 to displace in lengthwise direction L relative to case 11 and piston head 3 formed in con rod face section. Piston head 3 is retained in hydraulic chamber 7 to displace relative to first hydraulic chamber 17. Piston head divides first hydraulic chamber 17 into front part 17a distant from con rod 2 and rear part located nearby con rod 2. Hydraulic damper has first system to transfer hydraulic fluid from front part 17a via extra valve 4 into rear part and second hydraulic chamber 18 is piston head moves along first hydraulic chamber 17 toward front part 17a. Hydraulic damper has second system to transfer hydraulic fluid from rear part and second hydraulic chamber 18 via ball check valve into front part 17a if piston head 3 moves along first hydraulic chamber toward rear part. ^ EFFECT: reduced wear and device length. ^ 24 cl, 7 dwg |
