A vehicular torsion bar suspension device, which comprises a front torsion bar spring and a rear torsion bar spring respectively installed at front and rear suspensions of the vehicle. The opposite ends of the front and rear torsion bar springs on the same side are connected mutually by a connection mechanism, and are connected with a vehicle frame through a positioning device. The connection mechanism is mounted between the front and rear torsion bar springs on the same side, so that a linkage relationship is established between the front and rear torsion bar springs. The device improves the vibration situation of the vehicle when driving the vehicle on an uneven ground, and prevents the vehicle frame and vehicle body skeleton from suffering torsional force. As a result, the usage life of the vehicle is prolonged.

A laundry processing apparatus according to the present invention comprises: a cabinet; a tub, arranged in the interior of the cabinet, for storing laundry water; longitudinal dampers connecting the cabinet and tub and supported on supporting ends on the tub, and supporting the tub as same hangs from the cabinet; upper guide pins fixed to the upper parts of the cabinet and extending vertically with respect to the supporting ends; upper transverse dampers, connecting the upper guide pins and tub and vertically movable along the upper guide pins, for reducing the horizontal vibration for the tub; lower guide pins fixed to the lower parts of the cabinet and extending vertically with respect to the supporting ends; and lower transverse dampers, connecting the lower guide pins and tub and vertically movable along the lower guide pins, for reducing the horizontal vibration for the tub. The laundry processing apparatus according to the present invention has the effect of reducing the horizontal vibration for the tub by means of the transverse dampers arranged on the upper and lower parts, with respect to the supporting ends, to connect the cabinet and tub.

The invention discloses a multi-layer sliding type shock insulation pedestal and a shock insulation method thereof. The shock insulation pedestal comprises a base, the base is provided with a lower end steel plate capable of transversely and vertically sliding on the base and returning, and the lower end steel plate is provided with a middle steel plate capable of transversely sliding on the lower end steel plate and returning. The middle steel plate is provided with a carrying steel plate capable of vertically sliding and returning on the middle steel plate. A multi-layer structure design is adopted, so that the horizontal vibration from the ground can be reduced to the maximum extent. The multi-layer sliding type shock insulation pedestal is of a plate-shaped structure, thereby being lighter, the gravity center is low, and the multi-layer sliding type shock insulation pedestal is more stable and can automatically return. The sliding between an upper steel plate and the lower steel plate can be achieved through steel balls, and the shock sensing is more sensitive. A special alloy ball is adopted inside the device, friction is reduced, and the shock absorption effect is improved. The multi-layer sliding type shock insulation pedestal can provide shock insulation protection for exhibits, and reduce the possibility that the exhibits are damaged under the action of external force.

The invention discloses a direct connection air compressor set. The direct connection air compressor set comprises a diesel engine and an air compressor. The diesel engine comprises a diesel engine crankshaft and a diesel engine crankshaft case. The air compressor comprises an air cylinder, an air compressor crankshaft case and an air compressor crankshaft. The diesel engine crankshaft is connected with a diesel engine flywheel, the diesel engine flywheel is arranged in a diesel engine flywheel shell, and the diesel engine flywheel shell is fixedly arranged on the diesel engine crankshaft case. The air compressor crankshaft is connected with an air compressor flywheel, the air compressor flywheel is arranged in an air compressor flywheel shell, and the air compressor flywheel shell is fixedly arranged on the air compressor crankshaft case. The air compressor flywheel shell is in direct rigid connection with the diesel engine flywheel shell, and the air compressor flywheel is in transmission connection with the diesel engine flywheel through a coupler. According to the direct connection air compressor set, direct connection between the air compressor and the diesel engine is achieved, and the direct connection air compressor set is small in occupied space, small in vibration as a whole, high in reliability and not prone to damage.

The invention belongs to the technical field of composite plate rolling and forming and particularly relates to a hydraulic screw-down corrugated roller rolling mill with special-shaped supporting rollers. The hydraulic screw-down corrugated roller rolling mill comprises a mechanical part and a hydraulic part. The mechanical part comprises the special-shaped supporting rollers, a special-shaped supporting roller balancing cylinder, a screw-down oil cylinder, working rollers, a frame and the like. The hydraulic part comprises a transmission side screw-down system, an operation side screw-down system, an upper special-shaped supporting roller balancing system, a self-adaptive lining plate system and an upper working roller balancing system. According to the hydraulic screw-down corrugated roller rolling mill, through the use of the special-shaped supporting rollers, the bending phenomenon of the working rollers under the working condition of large rolling force is avoided, and the service life of the working rollers is prolonged; and through the use of the self-adaptive lining plate system, the stability of the rolling mill is improved, the horizontal vibration of supporting roller bearing seats and working roller bearing seats in the frame is reduced, and the yield of composite plates is increased.
