Description

Technical Field

[0001] This invention relates to the field of hydraulic system technology for car carriers, specifically to an integrated front pillar hydraulic oil tank for car carriers. Background Technology

[0002] Car carriers, as specialized vehicles for transporting cars, typically use hydraulic systems to lift or secure the vehicles being transported. In traditional hydraulic systems, the hydraulic oil tank often has a tank-like structure and is located in the middle to rear of the vehicle frame, as shown in the attached... Figure 1 As shown.

[0003] However, the hydraulic pump in car carriers is typically installed near the front of the vehicle, resulting in a relatively long connecting hose between the pump and the oil tank. Since the hydraulic pump must overcome both frictional and local resistance when drawing oil, a long hose significantly increases this resistance, potentially leading to cavitation, unstable system pressure, or even pump damage. Furthermore, the traditional tank-like oil tank is installed independently and not integrated with the frame pillars, failing to provide structural reinforcement and wasting the vehicle's structural resources. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated front pillar hydraulic oil tank for car carriers. By vertically integrating the tubular oil tank into the front pillar, there is a large height difference between the oil and the hydraulic pump. The gravity of the oil is used to reduce the oil suction resistance of the hydraulic pump, and the strength of the pillar is enhanced by the oil tank structure, while also taking into account the convenience of installation and maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated front pillar hydraulic oil tank for a car carrier includes an oil tank body; its core improvement lies in that: the oil tank body is a tubular body, and the oil tank body is vertically fixed to the front pillar at the very front of the car carrier; an oil pipe is connected to the bottom of the oil tank body, and an auxiliary flow port communicating with the outside is opened on the top of the oil tank body.

[0006] By adopting the above scheme, the tubular oil tank is vertically arranged on the front pillar. At this time, there is a large height difference between the oil and the hydraulic pump, and the hydraulic pump is closer to the oil tank, which greatly shortens the oil suction path, reduces frictional resistance, and improves the stability of the hydraulic system. Secondly, the tubular oil tank is integrated into the front pillar as a structural component, which can effectively share the load borne by the pillar and improve the rigidity and deformation resistance of the whole vehicle structure.

[0007] As a preferred embodiment of the integrated front pillar hydraulic oil tank for a car carrier, a dirt-proof mesh cover covering the flow inlet is installed on the top of the tank body. The dirt-proof mesh cover is located under the rain shield fixed on the top of the front pillar. By installing the dirt-proof mesh cover at the flow inlet, the air pressure inside and outside the tank is balanced to prevent air suction, and external impurities are prevented from entering the oil.

[0008] As a preferred embodiment of the integrated front column hydraulic oil tank of the car carrier, a return oil pipe is fixed in the inner cavity of the oil tank body along the height direction, wherein the top of the return oil pipe extends to the top of the inner cavity of the oil tank body, and the bottom of the return oil pipe extends to the bottom of the inner cavity of the oil tank body and penetrates out of the oil tank body; the built-in return oil pipe guides the oil discharge, mainly applied to the filling during oil replacement in maintenance, and when the new oil reaches the top of the return oil pipe, the oil flows out of the return oil pipe, at which time the oil filling should be stopped.

[0009] As a preferred embodiment of the integrated front column hydraulic oil tank of the car carrier, a plurality of positioning studs are fixed on the outer side of the oil tank body and linearly arranged along the height direction, and the oil tank body is detachably fixed on the front column through the cooperation of the positioning studs and nuts; at least one limiting column is fixed on the outer side of the oil tank body and located in the same plane as the positioning studs; the positioning studs and the limiting column cooperate to realize quick disassembly and assembly, which is convenient for maintenance.

[0010] As a preferred embodiment of the integrated front column hydraulic oil tank of the car carrier, two groups of oil tank bodies are provided, and the two groups of oil tank bodies are vertically fixed on the inner sides of the left front column and the right front column, respectively; the left-right symmetrical double-oil tank structure can expand the capacity or provide redundancy to adapt to different working conditions.

[0011] As a preferred embodiment of the integrated front column hydraulic oil tank of the car carrier, the oil pipe includes three parts: a left section oil pipe, a middle section oil pipe and a right section oil pipe; the side wall of the middle section oil pipe is provided with an oil inlet and an oil outlet, respectively; the oil pipe is hidden under the oil path front guard plate of the car carrier; the left section oil pipe, the middle section oil pipe and the right section oil pipe are connected by threads; the left section oil pipe is connected to the bottom of the oil tank body of the left front column by threads; the right section oil pipe is connected to the bottom of the oil tank body of the right front column by threads; the left section oil pipe, the middle section oil pipe and the right section oil pipe are connected by threads, which can simplify the manufacturing process and reduce the difficulty of transportation and installation.

[0012] The second technical problem to be solved by the present application is to provide an integrated front column hydraulic oil tank of a car carrier, in order to realize the cleaning of impurities on the surface of the anti-fouling cover, the anti-fouling cover is provided as a rotating cover, and the rotating cover is automatically rotated by wind force during driving, which can effectively clean the impurities accumulated on the surface of the rotating cover.

[0013] To achieve the above-mentioned purposes, the present application adopts the following technical solutions: Based on the above-mentioned scheme, the anti-fouling cover is a rotating cover, which is horizontally installed at the flow assisting opening, and a plurality of rotating side wings are fixed on the outer side wall of the rotating cover and arranged in a circumferential array; wind baffles are fixed on the front and rear sides of the oil tank body and block the rotating cover; the wind baffles on the front and rear sides are provided with air guide openings corresponding to the positions of the rotating side wings.

[0014] By adopting the above scheme, since the anti-fouling net cover is a rotating net cover, when the car is running, the wind blows directly from the air guide opening to the rotating side wing, drives the rotating net cover to rotate, and under the action of centrifugal force, can effectively clean the impurities accumulated on the surface of the rotating net cover, thereby playing a role of cleaning impurities.

[0015] The third technical problem to be solved by the present application is to provide a car integral front upright column hydraulic oil tank, in order to reduce the oil leakage caused by oil fluctuation due to sudden braking of the car, an oil blocking plate is installed in the oil tank, which can further limit the oil fluctuation caused by sudden braking of the car, thereby avoiding oil leakage.

[0016] To achieve the above object, the present application adopts the following technical scheme: Based on the above scheme, the front and rear inner walls of the top of the oil tank body are fixed with oil blocking plates inclined and lowered to the middle, and openings are reserved between the oil blocking plates on the front and rear inner walls; wherein the two oil blocking plates on the front and rear inner walls are on the same horizontal plane or have a certain height difference.

[0017] By adopting the above scheme, if the car brakes suddenly during the forming process, at this time the oil surface tilts forward, at this time under the blocking action of the oil blocking plate on the front inner wall of the oil tank body, the oil leakage from the flow assisting opening caused by excessive forward tilting of the oil surface can be effectively inhibited; if the car accelerates suddenly, at this time the oil surface tilts backward, at this time under the blocking action of the oil blocking plate on the rear inner wall of the oil tank body, the oil leakage from the flow assisting opening caused by excessive backward tilting of the oil surface can be effectively inhibited.

[0018] The beneficial effects of the present application are: 1. Reduce oil suction resistance: the tubular oil tank is vertically arranged in the front upright column, at this time there is a large height difference between the oil and the hydraulic pump, and the hydraulic pump is closer to the oil tank, greatly shortening the oil suction path, reducing the resistance along the way, and improving the stability of the hydraulic system.

[0019] 2. Enhance the strength of the column: the tubular oil tank is integrated as a structural part in the front upright column, which can effectively share the load borne by the column and improve the structural rigidity and anti-deformation ability of the whole vehicle.

[0020] 3. Optimal design of oil return: the built-in oil return pipe guides the oil discharge, mainly applied to the filling of oil replacement during maintenance, when the new oil reaches the top of the oil return pipe, the oil flows out from the oil return pipe, at this time the oil filling should be stopped.

[0021] 4. Modular installation: the positioning stud cooperates with the limiting column to realize quick disassembly and assembly, which is convenient for maintenance; the left-right symmetrical double oil tank structure can expand the capacity or provide redundancy, and adapt to different working conditions.

[0022] 5. Segmented tubing connection: The left, middle and right sections of the tubing are connected by threads, which simplifies the manufacturing process and reduces the difficulty of transportation and installation.

[0023] 6. Combining breathability, anti-fouling, and cleaning: By installing an anti-fouling mesh cover at the flow inlet, the air pressure inside and outside the box is balanced to prevent air suction, and external impurities are prevented from entering the oil. In order to further clean the impurities on the surface of the anti-fouling mesh cover, the anti-fouling mesh cover is set as a rotating mesh cover. The rotating mesh cover is automatically rotated by the wind during the vehicle, which can effectively clean the impurities accumulated on the surface of the rotating mesh cover.

[0024] 7. Prevent oil leakage: In order to reduce oil leakage caused by oil fluctuations due to sudden braking and other situations in the car carrier, an oil baffle plate is installed inside the oil tank. This can further limit oil fluctuations caused by sudden braking and other situations in the car carrier, thereby preventing oil leakage. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, as Figures 2 to 4 As shown, an integrated front pillar hydraulic oil tank for a car carrier is applied to a car carrier 2. It includes an oil tank body 1. The oil tank body 1 is a tubular body (high-strength square tube) and is vertically fixed to the front pillar 3 at the front end of the car carrier 2. There are two sets of oil tank bodies 1, which are vertically fixed to the inner side of the left front pillar 3a and the inner side of the right front pillar 3b, respectively. The symmetrical double oil tank structure can expand the capacity or provide redundancy to adapt to different working conditions.

[0029] like Figure 4 , Figure 9As shown, the bottom of the fuel tank body 1 is connected to an oil pipe 4, which consists of three parts: a left section oil pipe 41, a middle section oil pipe 42, and a right section oil pipe 43. The middle section oil pipe 42 has an oil inlet 44 and an oil outlet 45 on its side wall. The oil pipe 4 is hidden under the front oil circuit guard plate 10 of the car carrier 2. The left section oil pipe 41, the middle section oil pipe 42, and the right section oil pipe 43 are connected in pairs by threads. The left section oil pipe 41 is connected to the bottom of the fuel tank body 1 of the left front pillar 3a by threads, and the right section oil pipe 43 is connected to the bottom of the fuel tank body 1 of the right front pillar 3b by threads. The left, middle, and right sections of the oil pipe are connected by threads, which simplifies the manufacturing process and reduces the difficulty of transportation and installation.

[0030] like Figures 5 to 6 As shown, the top of the oil tank body 1 is provided with an auxiliary flow port 5 that communicates with the outside; the top of the oil tank body 1 is also equipped with a dirt-proof mesh cover 6 that covers the auxiliary flow port 5, wherein the dirt-proof mesh cover 6 is located below the rain shield 11 fixed to the top of the front column 3; by installing the dirt-proof mesh cover 6 at the auxiliary flow port 5, the air pressure inside and outside the tank is balanced to prevent air suction, and external impurities are prevented from entering the oil.

[0031] like Figures 5 to 7 As shown, a return oil pipe 7 is also fixed in the inner cavity of the oil tank body 1 along its height direction. The top of the return oil pipe 7 extends to the top of the inner cavity of the oil tank body 1, and the bottom of the return oil pipe 7 extends to the bottom of the inner cavity of the oil tank body 1 and passes through the bottom of the inner cavity of the oil tank body 1 to the outside of the oil tank body 1. The built-in return oil pipe 7 guides the oil to be discharged and is mainly used for adding oil during maintenance and repair. When the new oil reaches the top of the return oil pipe 7, the oil flows out from the return oil pipe 7, and the oil filling should be stopped at this time.

[0032] like Figure 8 As shown, multiple positioning studs 8 are fixed on the outer side of the fuel tank body 1, which are linearly arrayed along its height direction. The fuel tank body 1 is detachably fixed to the front column 3 by the cooperation of the positioning studs 8 and nuts. At least one limiting post 9 is also fixed on the outer side of the fuel tank body 1, which is located on the same plane as the positioning bolt. The positioning studs 8 and the limiting post 9 cooperate to achieve quick disassembly and assembly, which is convenient for maintenance.

[0033] Working principle of Example 1: Two tubular (high-strength square tube) oil tanks are vertically arranged on the front pillar 3. Their overall oil storage capacity is no less than that of a traditional tank-type hydraulic oil tank. When the hydraulic system is working, the hydraulic pump draws oil from the outlet 45, and the oil enters the pump body through the left / right section oil pipe 43 and the middle section oil pipe 42. When returning oil, it returns to the oil pipe 4 through the inlet 44 and then back to the main body of the oil tank. The flow aid 5 and the anti-fouling cover 6 ensure the balance of air pressure inside and outside the tank, avoiding cavitation due to oil reduction. Due to the large height difference between the oil and the hydraulic pump, and the fact that the hydraulic pump is closer to the oil tank, the oil suction path is significantly shortened, reducing friction resistance and improving the stability of the hydraulic system. Secondly, the tubular oil tanks are integrated into the front pillar 3 as a structural component, which can effectively share the load borne by the pillar and improve the rigidity and deformation resistance of the entire vehicle structure.

[0034] Example 2, as Figures 10 to 11 As shown, the difference between this embodiment and Embodiment 1 is only that, based on Embodiment 1, the anti-fouling mesh cover is a rotating mesh cover, which is horizontally rotated and installed at the flow aid inlet. Multiple rotating side wings 12 are fixed on the outer side wall of the rotating mesh cover in a circumferential array. Wind shields 13 that block the rotating mesh cover are fixed on the front and rear sides of the oil tank body 1. Wind shields 13 located on the front and rear sides are provided with air guides 14 corresponding to the location of the rotating side wings 12.

[0035] Working principle of Example 2: Since the anti-fouling net cover is a rotating net cover, when the car carrier is in motion, the wind blows directly from the air guide 14 to the rotating side wing 12. The rotating side wing 12 drives the rotating net cover to rotate. Under the action of centrifugal force, it can effectively clean the impurities accumulated on the surface of the rotating net cover, thereby playing the role of cleaning impurities.

[0036] Example 3, as Figures 12 to 13 As shown, the difference between this embodiment and embodiment two is that, based on embodiment two, oil blocking plates 15 that are inclined downwards towards the middle are fixed on the front and rear inner walls of the top of the oil tank body 1, and an opening is reserved between the oil blocking plates 15 on the front and rear inner walls; wherein, the two oil blocking plates 15 on the front and rear inner walls are located on the same horizontal plane.

[0037] Working principle of Example 3: During the formation of the car carrier, if the car carrier brakes suddenly, the oil surface tilts forward. At this time, the oil baffle plate 15 on the inner front wall of the oil tank 1 can effectively prevent the oil surface from leaking from the flow port 5 due to excessive forward tilting. If the car carrier accelerates suddenly, the oil surface tilts backward. At this time, the oil baffle plate 15 on the inner rear wall of the oil tank 1 can effectively prevent the oil surface from leaking from the flow port 5 due to excessive backward tilting.

[0038] Example 4, as Figures 14 to 15As shown, the difference between this embodiment and embodiment three is that, based on embodiment three, the two oil-blocking plates 15 located on the front and rear inner walls are located on the same horizontal plane, which is replaced by: the two oil-blocking plates 15 located on the front and rear inner walls have a certain height difference. The working principle of embodiment four is the same as that of embodiment three.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
