The invention relates to a crash-tolerant system arrangement in an engine compartment which is arranged in the front end region of a motor vehicle, comprising an internal combustion engine which is arranged in the engine compartment with an engine block (1), an exhaust-gas manifold (2) which receives exhaust gases of the internal combustion engine, an exhaust-gas turbocharger (3) which is assigned to the internal combustion engine with an exhaust-gas inlet (5) and an exhaust-gas outlet (6), and an exhaust-gas purification system (7) with a substantially cylindrical first catalytic-converter housing (9) which is arranged in front of the exhaust-gas turbocharger (3) in the driving direction (8) and in which a first exhaust-gas catalytic-converter element is arranged. Here, a first exhaust-gas guide element (10) is provided for guiding the exhaust gas from the exhaust-gas outlet (6) of the exhaust-gas turbocharger (3) to the first catalytic-converter housing (9), which first exhaust-gas guide element (10) extends from the exhaust-gas outlet (6) of the exhaust-gas turbocharger (3) to an inlet cone (11) of the first catalytic-converter housing (9) and can transmit a pressure force, which acts on the first catalytic-converter housing (9) substantially counter to the driving direction (8), at least partially to the exhaust-gas turbocharger (3). The exhaust-gas turbocharger (3) is connected mechanically by way of a first fastening device (12) to the exhaust-gas manifold (2) and by way of a second fastening device (13) to the engine block (1), wherein the first and the second fastening device (12, 13) are designed in such a way that a release of the connection of the exhaust-gas turbocharger (3) to the exhaust-gas manifold (2) and / or a release of the connection of the exhaust-gas turbocharger (3) to the engine block (1) take / takes place within a predefined upper value range for the pressure force.

The invention belongs to the technical field of anti-vibration hammers and particularly relates to an automatic locking anti-vibration hammer. The hammer comprises a main hammer head and a connectingrod, the two ends of the connecting rod are connected with connecting ejector blocks, and the connecting ejector blocks are connected with the main hammer head which is connected with an adjusting balancing weight; and a pressing arc plate is arranged in the connecting ejector block and connected with a pressing bolt. The middle part of the connecting rod is connected with a connecting sleeve; theconnecting sleeve is sequentially connected with a middle connecting block, a middle connecting rod and a self-locking wire clamp; the self-locking wire clamp comprises an upper clamping plate, a lower clamping plate and a locking pull rod, the lower part of the locking pull rod is provided with second ring teeth, the outer sides of the second ring teeth are provided with locking ring plates, theinner side surfaces of the locking ring plates are provided with first ring teeth, the outer side surfaces of the locking ring plates are connected with pressure springs and guide rods, and the end part of the locking pull rod is provided with a threaded head; the anti-vibration requirements of various overhead lines can be met by adjusting the balancing weight, the position and the angle of thehammer head and other measures, the rapid installation on the overhead lines can be achieved, and meanwhile, the loosening of wire clamping after long-term work can be effectively avoided.

The invention relates to a coaxiality adjustment device for camera modules, which comprises a fixed module unit, a module clamping unit, a six-axis unit and a connecting unit. The module clamping unitis supported by the six-axis unit, and can be driven by the six-axis unit to move relative to the fixed module unit. The coaxiality adjustment device for camera modules of the invention has the advantages of simple overall structure, high coaxiality adjustment precision, and convenience of operation.
