The invention provides an auxiliary hoisting device applied to the assembly of a turbine high-pressure valve, relates to an auxiliary hoisting device applied to the assembly of a turbine valve, and aims to solve the problems that when the conventional turbine high-pressure regulating valve is directly bundled by lifting ropes to be hoisted during valve assembly, the preparation workload before hoisting is large, the hoisting process is unstable, so that the potential safety hazard is easy to generate, and the clamping force is insufficiently large, the lifting ropes are easy to loosen and the valve is bumped and damaged. A mold cavity of an upper shell horizontally penetrates through the upper shell, a mold cavity of a lower shell horizontally penetrates through the lower shell, the upper shell and the lower shell are adhered, the mold cavity of the upper shell and the mold cavity of the lower shell are arranged oppositely, the upper shell and the lower shell are connected, an upper lining tile is fixedly connected with the interior of the mold cavity of the upper shell, a lower lining tile is fixedly connected with the interior of the mold cavity of the lower shell, the upper lining tile and the lower lining tile are arranged oppositely, a turbine high-pressure valve is respectively matched with the upper lining tile and the lower lining tile, and a lifting lug I and a lifting lug II are fixedly connected with the top of the upper shell. The auxiliary hoisting device disclosed by the invention is applied to the hoisting of the turbine high-pressure valve.

The invention provides an arranging structure for sound units (4 and 4a) and storage boxes (2 and 2a) of a vehicle instrument board. The sound units (4 and 4a) and the storage boxes (2 and 2a) are adjacently arranged on the vehicle instrument board. The arranging structure is characterized in that the sound units (4 and 4a) and the storage boxes (2 and 2a) are arranged in the manner that at least part of the storage boxes (2 and 2a) coincide with the sound units (4 and 4a) in the height direction.

The invention discloses a steering gear assembly and a vehicle steering system. The steering gear assembly comprises a steering gear (5) and an auxiliary vehicle frame (6). At least two X-direction installation points (7) are arranged between the steering gear (5) and the auxiliary vehicle frame (6). The steering gear assembly is characterized by further comprising at least one Z-direction installation point (8), the one or more Z-direction installation points (8) are connected with the auxiliary vehicle frame (6) through one or more X-direction installation points (7) corresponding to the Z-direction installation points (8). The steering gear assembly is simple in structure, easy to install, small in required design space and capable of effectively solving the problems that the input moment of a tubular column type electric power-assisted steering gear fluctuates and a lower cross joint of a steering transmission shaft vibrates due to the fact that a steering gear pull rod receives excitation of a road surface.

The invention discloses a passenger bus air filter and exhaust silencer fixing mechanism. The passenger bus air filter and exhaust silencer fixing mechanism comprises an exhaust comprehensive support, an air filter support and a silencer hanger, wherein the exhaust comprehensive support is respectively connected with the air filter support and the silencer hanger; the exhaust comprehensive support comprises a support main body, a silencer installation hanger and an air filter installation support; the air filter support comprises a first hoop and an installation base; the silencer hanger comprises a second hoop and an M-shaped support. The passenger bus air filter and exhaust silencer fixing mechanism solves the problems that the fixing positions of the air filter and the exhaust silencer are independently arranged, the occupied space is large, the inspection cannot be conveniently conducted by operating workers, etc.

The invention discloses a civil truck suspension assembly. The civil truck suspension assembly comprises a left front suspension assembly, a right front suspension assembly and a rear suspension assembly, wherein the left front suspension assembly comprises a front support assembly, a front rubber mat assembly and a front supporting leg assembly; the right front suspension assembly and the left front suspension assembly are symmetric; and the rear suspension assembly comprises a rear suspension connecting plate assembly and a transmission connecting plate assembly. Compared with the prior art, the civil truck suspension assembly has the characteristics that six-point suspension in the prior art is changed into three-point suspension including the left front suspension assembly, the right front suspension assembly and the rear suspension assembly, the span is small, the precision is easily controlled, fixing points of the three-point suspension are easily located on the same plane, the three-point suspension can be attached to a frame well, therefore, the shaking state is reduced to a maximum extent during idling of an engine of a whole vehicle, the number of the fixing points is small, the lightweight effect is remarkable, and the production time is shortened.
