Embodiment Construction
[0013] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0014] Please refer to the attached figure 1 and 2 , the embodiment of the present invention includes:
[0015] An electro-hydraulic tilting pressure absorbing device on an outboard motor has four main structures: a trim oil cylinder 1, a push rod assembly 2, and a free piston 3. One end of the push rod assembly 2 is provided with a push rod piston 4, and the other end is provided with a sleeve for external docking. The trim cylinder 1 is an airtight cylinder with both ends sealed, and the push rod piston 4 passes through the upper end cover of the trim cylinder 1 and fits in the inner chamber of the trim cylinder 1 . The upper end cover of th...

The invention provides an electric hydraulic upwarp pressure absorbing device for an outboard motor and relates to the field of auxiliary structures of outboard motors. The electric hydraulic upwarp pressure absorbing device comprises a longitudinally-inclined oil cylinder, a pushing rod assembly and a free piston. A pushing rod piston is arranged at one end of the pushing rod assembly and penetrates through an upper end cover of the longitudinally-inclined oil cylinder to be arranged in an inner cavity of the longitudinally-inclined oil cylinder in a matched mode. A one-way valve communicating with the exterior and adopting one-way oil entering is further arranged on the upper end cover of the longitudinally-inclined oil cylinder. The pushing rod piston is provided with two flow passes communicating with inner cavities of the upper side and the lower side of the pushing rod piston, one of the flow passes conducts one-way return stop through a steel ball supported by a spring, and hydraulic oil flows from the inner cavity of the upper side of the pushing rod piston to the inner cavity of the lower side of the pushing rod piston in a one-way mode. The other flow pass conducts floating return stop through a single steel ball, and the hydraulic oil flows from the inner cavity of the lower side of the pushing rod piston to the inner cavity of the upper side of the pushing rod piston in a one-way mode. The free piston is further fixed to the end face of the pushing rod piston.
Description
technical field [0001] The invention relates to the field of auxiliary structures on outboard motors, in particular to an electrohydraulic lifting pressure absorbing device on outboard motors. Background technique [0002] At present, military assault boats, speedboats, and civilian small boats all use outboard propulsion equipment at the rear end of the hull, referred to as outboard motors. , the machine is located outboard at the rear end of the hull and is axially connected with the side of the boat. When in use, most of the outboard motors are located at the bottom of the boat. Due to the unevenness of the river bottom, there are many protruding reefs and debris located in Hanoi. Therefore, in order to prevent the outboard motor from hitting the reefs and debris when the boat is running at high speed, The outboard motor needs to be tilted to avoid damage due to impact, but if you are not careful, the outboard motor will also be damaged due to hitting reefs and sundries....
