Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a double-barrelled hydraulic shock absorber that electric motor car used which characterized in that: comprises an outer tube 1, an inner tube 2, an upper end cover 6 and an oil storage cavity 7; the inner pipe 2 is nested in the outer pipe 1 through an upper end cover 6 arranged at the upper end of the inner pipe, the inner pipe 2 is nested with a working piston 3, and the working piston 3 is fixed with a hanging ring 5 through a piston rod 4; the oil storage cavity 7 is arranged below the outer tube 1, and the oil storage cavity 7 is communicated with the cavity of the outer tube 1 through a valve body for controlling on-off. The lower end of the outer pipe 1 penetrates through the oil storage cavity 7 to extend to be provided with a hanging ring 5, the hanging ring 5 is used for being connected to an electric vehicle main body, and in common use, bearings are embedded in the hanging ring 5 to improve the working performance of the electric vehicle.
In the track structure of the preferred embodiment, the outer tube 1, the inner tube 2, the upper end cap 6 and the working piston 3 with the piston rod 4 constitute a working component of the shock absorber, the piston 3 is made of an elastic material (the piston 3 is provided with a damping hole structure through which hydraulic oil can flow), under the action of external force, the piston rod 4 can slide in the inner tube 2, and the inner tube 2 can slide in the outer tube 1 together with the upper end cap 6 (the bottom end of the inner tube 2 is also provided with the damping hole structure), so that a dual shock absorption effect is formed, a certain amount of hydraulic oil is filled in the inner tube 2, a certain amount of hydraulic oil is filled in the middle lower part between the inner tube 2 and the outer tube 1, and a gas (generally nitrogen gas) is filled in the upper part between the inner tube 2 and the outer tube 1.
In the embodiment, the oil storage cavity 7 arranged at the lower end of the outer tube 1 is used for supplementing hydraulic oil to the inner cavity of the outer tube 1, and when the oil storage cavity 7 is not used at ordinary times, a passage from the oil storage cavity 7 to the inner cavity of the outer tube 1 is closed through the valve body; the hydraulic oil reservoir is opened only when the hydraulic oil needs to be supplemented, and a certain pressure is applied to the oil storage cavity 7 after the hydraulic oil reservoir is opened, so that the hydraulic oil flows to the inner cavity of the outer pipe 1.
Specifically, the oil storage cavity 7 is fixed on the lower end face of the outer tube 1 through a fastening thread 8; namely, a flange with a radial hole is formed on the lower end surface of the outer pipe 1, the oil storage cavity 7 also forms a bulge with a corresponding radial hole, and the oil storage cavity 7 and the outer pipe 1 can be fastened together by connecting the radial holes of the two parts through fastening threads 8, as shown in fig. 2; because the oil storage cavity 7 jolts up and down along with the shock absorber, the fixing structure is better, and the fastening effect of the fastening thread 8 can meet the requirement.
Specifically, the oil storage cavity 7 is communicated with the outer pipe 1 through a first through hole 12, a rotary valve 11 and a second through hole 13, and the rotary valve 11 is provided with a rotary rod body 15 and a valve body through hole 14 which is radially communicated with the rotary rod body; this embodiment has specifically adopted the rotary valve 11 of taking the rotatory body of rod 15 to realize the break-make, and the rotatory body of rod 15 and rotary valve 11 structure as an organic whole, and the rotary valve 11 is arranged in 1 outsidely in the outer tube, and inside the rotatory body of rod 15 embedding outer tube 1, can change valve body through-hole 14 pointing through rotary valve 11, is the open mode when valve body through-hole 14 and first through-hole 12 and second through-hole 13 coaxial line, is the closed mode when valve body through-hole 14 is perpendicular with first through-hole 12 and second through-hole 13 axis.
Specifically, an oil pushing plate 9 is placed in the oil storage cavity 7, the oil pushing plate 9 is in threaded connection with a screw rod 10, and the screw rod 10 controls the oil pushing plate 9 to lift through a screw action. So as to better apply pressure to the hydraulic oil, and press the hydraulic oil into the inner cavity of the outer pipe 1, and the embodiment is realized by rotating the screw rod 10 to make the oil pushing plate 9 rise to press the hydraulic oil.
Specifically, the oil storage chamber 7 is made of a transparent material having a certain strength. The transparent material can see the oil level change of the hydraulic oil in the oil storage cavity 7, so that the hydraulic oil can be more accurately added into the inner cavity of the outer tube 1. Similarly, the oil storage cavity 7 can be marked with scales, and the accuracy is higher.
The working principle is as follows: at ordinary times, when the shock absorber is in a working state, the rotary valve 11 on the shock absorber is in a closed state, and the oil storage cavity 7 is not communicated with the hydraulic oil in the inner cavity of the outer pipe 1; when the shock absorber is used and oil leaks, hydraulic oil needs to be supplemented into the inner cavity of the outer tube 1, firstly, the rotary valve 11 is rotated to enable the valve body through hole 14, the first through hole 12 and the second through hole 13 to be coaxial, namely, the valve body through hole is in an open state, then the screw rod 10 is rotated to drive the oil pushing plate 9 to ascend to extrude the hydraulic oil in the oil storage cavity 7, and the hydraulic oil flows into the inner cavity of the outer tube 1 through the first through hole 12, the valve body through hole 14 and the second through hole 13 in sequence; when the hydraulic oil flows in to reach the preset amount, the rotary valve 11 is closed.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
