The utility model discloses a motorcycle front magnetorheological damper and motorcycle, including working cylinder, guider assembly, piston assembly, floating piston assembly, magnetorheological fluid, outer tube support assembly, ECU control unit and sensor, guider assembly, piston assembly and floating piston assembly are located in the inside of working cylinder, and piston assembly includes built -in solenoid and damping passage, and damping passage penetrates the upper and lower end of piston assembly, and magnetorheological fluid fills the working cavity between guider assembly and floating piston assembly, and, outer tube support assembly is at least partially coated in the outside of working cylinder, and is connected with guider assembly, and ECU control unit and solenoid electric connection are used for the signal adjustment input to solenoid's current according to sensor, like this through solenoid and the combination of magnetorheological fluid, ECU control unit can real -time regulation magnetic field intensity, change the viscosity of magnetorheological fluid to dynamic control damping force.

The utility model discloses a kind of gas tank flow regulating valves, it includes installation valve body, regulating valve piece and gas outlet component, the upper end of this installation valve body is recessed with adjusting slot, the regulating valve piece can be adjusted and connect in this adjusting slot, the lower side end of this adjusting slot is opened with gas outlet hole, the gas outlet component is fixedly connected in this gas outlet hole, the inner bottom of this adjusting slot is equipped with sealing cone groove, the bottom of this regulating valve piece is equipped with the sealing cone head compatible with this sealing cone groove, the sealing cone head is embedded into the sealing cone groove and forms conical surface sealing connection.The gas tank flow regulating valve of the utility model is realized by screw thread transmission the up-and-down movement of regulating valve piece, so that sealing cone head generates controllable gap in sealing cone groove, to realize the accurate regulation of gas flow, in closed state, sealing cone head and sealing cone groove are closely combined, form high-efficiency conical surface sealing, ensure that gas circuit is completely cut off.

The utility model discloses an adjusting device of an automobile hub spinning machine, which belongs to the technical field of automobile hub spinning machines and comprises a base, a plurality of limit shafts are slidably connected in the base, the tops of the limit shafts are fixedly connected with a supporting plate, the bottoms of the limit shafts are fixedly connected with second plates, and the second plates are fixedly connected with the supporting plate. The bottom of the second plate is rotationally connected with a deflection mechanism. A pushing mechanism meshed with the fluted disc is slidably connected into the base, a second air cylinder slidably connected with one end of the pushing mechanism is fixedly connected into the base, and the other end of the second air cylinder is connected with a ventilation mechanism. Vertical lifting adjustment of the lower die base is achieved through the deflection mechanism, the lever principle is used for amplifying displacement, adjusting sensitivity is improved, air pressure change is converted into fluted disc rotating motion through the pushing mechanism, transmission stability and adjusting precision are ensured, and power is transmitted through the ventilation mechanism by means of air pressure. And the stability of the lower die holder in the lifting process is ensured.

This utility model discloses a presser foot head with automatic pressure adjustment, including a presser foot handle and a presser foot base plate disposed at the bottom of the presser foot handle; the bottom of the presser foot base plate has a recess, and multiple movable plates are engaged in the recess; a first spring rod is longitudinally arranged between the movable plates and the top of the recess; a first airbag is provided at the bottom of the movable plate, and a contact plate is provided at the bottom of the first airbag; a second spring rod is respectively provided on both sides of the recess at the connection of the movable plates, and a friction plate is provided on the second spring rod; a second airbag is provided between the friction plates that are in contact on both sides of the same movable plate through a connecting rod; by setting a linkage structure of movable plates, first airbags and second airbags that are slidably connected to the recess of the presser foot base plate, the friction force between the movable plates and the friction plates can be automatically adjusted according to the fabric thickness, thereby dynamically controlling the pressure applied by the presser foot to the fabric; achieving precise pressing.
