2results about How to "Disperse impact force" patented technology

The application provides a subframe and a vehicle. The subframe comprises a front cross beam, a rear cross beam and two longitudinal beams, the front ends of the longitudinal beams are connected to the front cross beam, and the tail ends of the longitudinal beams are connected to the rear cross beam; at least two induction grooves are arranged on the upper surfaces of the longitudinal beams in the length direction, and the depth of the induction groove closer to the rear cross beam is greater than the depth of the induction groove closer to the front cross beam in the direction from the front cross beam to the rear cross beam. The subframe increases the collapse energy absorption structure under the condition of meeting the short front suspension requirement, can produce collapse deformation to absorb the collision energy when the collision occurs, can sink the engine located above the subframe and ensure that the tail end of the engine sinks more greatly, so as to prevent the tail end of the engine from being excessively upturned or moved backward to press the cabin, thereby effectively protecting the cabin and passenger safety.

This utility model discloses a hydraulic oil tank for a hydraulic oil pump. The tank body has cross-sections formed at a set of diagonal sides, one of which has an oil suction port and the other has an oil return port. The oil suction port's pipe extends into the tank body and connects to a coarse filter. The coarse filter is connected to a funnel-shaped expansion suction head via a threaded connector. The oil return port's outlet is connected to a fine filter, which is connected to a one-way throttle valve. The one-way throttle valve is connected to a flow-regulating pipe, which is curved and located within the tank body. This invention adds a funnel-shaped expansion suction head at the oil suction port to reduce suction resistance and minimize inlet disturbance. The addition of a flow-regulating pipe at the oil return port slows down the return oil flow. Combined with the 45° oblique cut, this effectively disperses the impact force of the oil and reduces disturbance. Furthermore, the diagonal distribution of the oil suction and return ports extends the oil flow path, promoting impurity sedimentation and air separation.
