The invention relates to a dump truck frame with functions of an auxiliary frame, which is not only provided with components required by an ordinary truck frame, but also is provided with major components of the auxiliary frame of the dump truck. A left longitudinal beam and a right longitudinal beam of the frame are respectively riveted with a slot type reinforcing beam with different cross sections, a turning shaft reinforcing plate, a container turning shaft sleeve and the like; the inner sides with a hydraulic cylinder are respectively riveted with a slot type hydraulic cylinder bracket reinforcing plate, and the inner sides of the left hydraulic cylinder bracket reinforcing plate and the right hydraulic cylinder bracket reinforcing plate are welded with a hydraulic cylinder bracket; and the left longitudinal beam and the right longitudinal beam of the frame are sequentially riveted with all components of the truck frame from the front part to the rear part. By adopting the structure, no auxiliary frame is needed, the functions of the ordinary truck frame can be realized and the functions of the auxiliary frame of the dump truck can be provided, the material consumption can bereduced and the overall mass of the whole truck can be improved, and thus the production cost can be decreased. The dump truck frame can be widely applied on dump trucks, in particular medium-sized and light dump trucks.

The invention discloses a power transmission system of a hybrid forklift and a control method thereof, including an engine assembly, a transmission system, a walking system, an operation system, a vehicle controller and a control system; the engine assembly includes a fuel engine assembly , an ISG motor assembly and a battery assembly, the ISG motor assembly drives the fuel engine assembly to start, and simultaneously drives the walking system and the operating system through the transmission system; the fuel engine assembly drives the ISG motor assembly to generate electricity and supplies power to the battery Assembly charging; the control system controls the clutches and brakes through the vehicle controller to switch between control modes. Beneficial effects: the present invention can make the fuel engine work in a high-efficiency area, and the ISG motor assembly assists the fuel engine to work under severe working conditions, thereby controlling the emission and fuel consumption of the fuel engine. When the fuel engine has surplus power, the ISG motor assembly acts as The generator charges the battery assembly.

The invention relates to an accelerator, aims at solving the problem that an existing electronic accelerator is low in average beam current power and cannot meet the using demand of the fields of material irradiation and the like, meanwhile gives consideration to using economical efficiency and provides an electronic helical accelerator. The electronic helical accelerator comprises a radio-frequency resonance cavity, a pair of ridge-shaped electrodes, a four-pole magnet, a deflection magnet, a beam current motion pore passage, a pore passage inlet, a pore passage outlet and a grid-control electronic gun, wherein the beam current motion pore passage comprises a beam current deflection pore passage and ridge-shaped electrode beam current pore passages, the four-pole magnet and the deflection magnet are arranged outside the beam current deflection pore passage, electronic beams led from the pore passage inlet is subjected to acceleration, focusing and deflection in the beam current motion pore passage and finally jet out of the pore passage outlet, and the whole acceleration process is finished. The electronic helical accelerator is high in radio-frequency utilization efficiency and good in using economical efficiency, effectively improves the average beam current power and can well meet the using demand of the fields of material irradiation and the like.
