Technical Field

[0001] The utility model relates to the technical field of truck manufacturing, in particular to an external automobile hydraulic retarder oil storage tank. Background Art

[0002] The function of the automobile hydraulic retarder is to enable the retarder when the car is decelerating or going down a long slope, so that the car can decelerate smoothly and avoid the wear and heat of the brake parts caused by the use of brakes. The hydraulic retarder is a device that uses liquid damping to produce a retarding effect, thereby slowing down the vehicle. Installing a hydraulic retarder in the transmission system of a truck has become an urgent need for truck manufacturers and users. At present, most of the oil storage tanks of automobile hydraulic retarders are placed on the upper rear part of the retarder. Since the retarder is generally connected to the rear of the automobile transmission with bolts, it belongs to the cantilever support method; the oil storage tank at the rear will increase the cantilever torque of the retarder, increase the force at the connection between the rear of the automobile transmission and the retarder, and thus cause adverse effects.

[0006] Preferably, the oil storage tank comprises an oil storage tank body, a top cover and an oil outlet pipe. The oil storage tank body is welded together by a surrounding plate, a vertical plate, an oil outlet pipe seat ring, a lower sealing plate, two baffles and an upper sealing plate. The surrounding plate is cut into a rectangular shape with steel plate and then bent into a groove shape; the vertical plate is cut into shape with steel plate and four bolt holes are processed on both sides thereof; the oil outlet pipe seat ring is cut into round steel and a pipe thread hole is processed in the center; the lower sealing plate is cut into a rectangular shape with steel plate and a round hole is processed in the center; the baffle is cut into a rectangular shape with steel plate; the upper sealing plate is cut into a rectangular shape with steel plate and a round hole is processed in the center. A circular hole with a step is machined at the center, and four threaded holes are evenly machined; first, the vertical plate and the enclosure are welded into a box shape, two baffles are welded in the middle section at an offset position, a lower sealing plate is welded at the lower end, and an upper sealing plate is welded at the upper end; the oil outlet pipe seat ring is inserted into the circular hole of the lower sealing plate and welded to the lower sealing plate; the oil outlet pipe is made of hexagonal steel, a round through hole is machined in the center, the upper section is machined into a smooth cylinder, the middle and upper section is machined into an external pipe thread, the middle and lower section is not machined to retain the hexagonal surface, and the lower section is machined into an external thread; the oil outlet pipe is installed into the oil outlet pipe seat ring of the oil storage tank body and tightened.

[0007] Preferably, after the oil inlet seat ring is cut from round steel, a circular hole is processed at the center position, and four hexagon socket bolt mounting countersunk holes are evenly processed around the circular hole. The lower section is processed into a smooth cylinder and the upper section is processed into an external thread; the filter screen is made of steel wire, and the filter screen base is processed from round steel; the filter screen base is welded to the lower end of the filter screen, and the oil inlet seat ring is welded to the upper end of the filter screen; the oil inlet seat ring, filter screen, and filter screen base welded parts are padded with rubber sealing gaskets and inserted into the circular holes of the upper sealing plate of the oil storage tank body, and fastened to the upper sealing plate of the oil storage tank body with four hexagon socket bolts.

[0008] Preferably, the upper top cover is formed by stamping after being cut from steel plate; the lower top cover is also cut from steel plate and a large circular hole is processed in the center, twelve small circular holes are processed evenly around the large circular hole, and finally the lower top cover is stamped into shape, the top cover screw tube is made of seamless steel pipe, the lower section is processed into internal threads, an internal retaining ring groove is processed in the inner hole of the middle section, and the inner hole of the upper section is processed into a matching size; the upper end of the top cover screw tube is firmly welded to the lower top cover; the top cover screw tube and the lower cover assembly are pressed into the upper top cover; a sawdust filter plate is installed in the top cover screw tube and an internal retaining ring is installed for positioning.

[0010] When refueling, unscrew the upper cover, lower cover and cover screw pipe assembly, and the retarder oil is added from the upper end of the oil tank body, and flows to the lower part of the oil tank body after being filtered through the filter. Since the upper end of the oil outlet pipe is higher than the lower sealing plate of the oil tank body, the impurities with higher density in the retarder oil remain at the bottom of the oil tank body, and the retarder oil enters the retarder from the oil outlet pipe through the oil delivery hose. When the retarder is working, the retarder oil-gas mixture enters the oil tank from the retarder through the oil delivery hose and the oil outlet pipe. Since the upper end of the oil outlet pipe is higher than the lower sealing plate of the oil tank body, the retarder oil left in the oil tank body has a certain cooling effect on the incoming oil-gas mixture. Under the action of the baffle, the oil-gas mixture takes an S-shaped path. After being further cooled by the filter, the oil-gas mixture moves upward, leaving the oil through the sawdust filter plate, and the air flows between the lower cover and the upper cover, and finally flows out through the twelve small holes on the lower cover. Similarly, air can also flow into the retarder in the opposite path to keep the retarder connected to the atmosphere. This kind of external automobile hydraulic retarder oil tank not only stores a certain amount of retarder oil, but also ensures that the retarder oil will not spray out from the retarder oil tank, and has a relatively simple structure and is easy to install. It can be widely used in trucks equipped with hydraulic retarders. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and beneficial effects of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model.

[0021] like Figures 1-2 As shown, the mounting base of the device, the left longitudinal beam 7 of the frame, is indicated by a double-dotted line and is made transparent. The utility model provides an external automobile hydraulic retarder oil tank. The oil tank bracket is welded by a bracket plate 2 and a reinforcing plate 3. The bracket plate 2 is cut into a rectangle with steel plate and then bent into a right angle, and four bolt holes are processed in the vertical section and two bolt holes are processed in the horizontal section. The reinforcing plate 3 is cut into a triangle with steel plate. The oil tank bracket is installed on the upper wing surface of the left longitudinal beam 7 of the frame with two bolts 4 and self-locking nuts 5, and the oil tank 1 is installed on the oil tank bracket with four bolts 4 and self-locking nuts 5. An oil delivery hose 6 is installed at the lower part of the oil outlet pipe at the lower end of the oil tank 1, and the other end of the oil delivery hose 6 is installed on the oil inlet of the hydraulic retarder.

[0022] like Figures 3 to 8As shown, the oil storage tank 1 is composed of an oil storage tank body, a top cover, an oil outlet pipe 109 and other components. The oil storage tank body is welded by a shroud 106, a vertical plate 107, an oil outlet pipe seat ring 108, a lower sealing plate 110, two baffles 111, and an upper sealing plate 114. The shroud 106 is cut into a rectangular shape with steel plates and then bent into a groove shape; the vertical plate 107 is cut into shape with steel plates and four bolt holes are processed on both sides; the oil outlet pipe seat ring 108 is cut into round steel and a pipe thread hole is processed at the center; the lower sealing plate 110 is cut into a rectangular shape with steel plates and a circular hole is processed at the center; the baffle 111 is cut into a rectangular shape with steel plates; the upper sealing plate 114 is cut into a rectangular shape with steel plates and a circular hole with a step is processed at the center, and four threaded holes are evenly distributed. First, the vertical plate 107 and the enclosure 106 are welded into a box shape, two baffles 111 are welded in the middle, a lower sealing plate 110 is welded at the lower end, and an upper sealing plate 114 is welded at the upper end; the oil outlet pipe seat ring 108 is inserted into the circular hole of the lower sealing plate 110 and welded to the lower sealing plate 110. The oil outlet pipe 109 is made of hexagonal steel, a round through hole is processed in the center, the upper section is processed into a smooth cylinder, the middle and upper section is processed into an external pipe thread, the middle and lower section is not processed to retain the hexagonal surface, and the lower section is processed into an external thread. The oil outlet pipe 109 is installed in the oil outlet pipe seat ring 108 of the oil storage tank body and tightened. After the oil inlet seat ring 105 is cut from round steel, a circular hole is processed in the center, and four hexagon socket bolt installation countersunk holes are evenly processed around the circular hole. The lower section is processed into a smooth cylinder and the upper section is processed into an external thread. The filter screen 113 is made of steel wire, and the filter screen base 112 is made of round steel. The filter screen base 112 is welded to the lower end of the filter screen 113, and the oil inlet seat ring 105 is welded to the upper end of the filter screen 113. The oil inlet seat ring 105, the filter screen 113, and the filter screen base 112 are welded together with a rubber sealing gasket 104 and inserted into the circular hole of the upper sealing plate 114 of the oil storage tank body, and fastened to the upper sealing plate 114 of the oil storage tank body with four hexagon socket bolts 115. The upper cover 101 is formed by stamping after cutting steel plates; the lower cover 116 is also cut from steel plates and a large circular hole is processed in the center, twelve small circular holes are evenly processed around the large circular hole, and finally the lower cover 116 is stamped. The top cover screw tube 102 is made of seamless steel pipe, the lower section is processed into internal threads, the inner hole of the middle section is processed into an inner snap ring groove, and the inner hole of the upper section is processed into a matching size. Weld the upper end of the top cover screw tube 102 firmly to the lower top cover 116; press the top cover screw tube 102 and the lower top cover 116 together into the upper top cover 101; install the sawdust filter plate 118 in the top cover screw tube 102 and install the inner snap ring 107 for positioning. After putting the sealing ring 103 on the oil inlet seat ring, screw the upper top cover 101, the lower top cover 116 and the top cover screw tube 102 together onto the oil inlet seat ring 105. The installation of a complete oil storage tank is completed.

[0023] When refueling, the upper cover 101, the lower cover 116 and the cover screw 102 are screwed off, and the retarder oil is added from the upper end of the oil storage tank body, and flows to the lower part of the oil storage tank body after being filtered through the filter 113. Since the upper end of the oil outlet pipe 109 is higher than the lower sealing plate 110 of the oil storage tank body, the impurities with higher density in the retarder oil are left at the bottom of the oil storage tank body, and the retarder oil enters the retarder through the oil delivery hose 6 from the oil outlet pipe 109. When the retarder is working, the retarder oil-gas mixture enters the oil storage tank from the retarder through the oil delivery hose 6 and the oil outlet pipe 109. Since the upper end of the oil outlet pipe 109 is higher than the lower sealing plate 110 of the oil storage tank body, the retarder oil remaining in the oil storage tank body has a certain cooling effect on the entering oil-gas mixture. Under the action of the baffle 111, the oil-gas mixture takes an S-shaped path. After being further cooled by the filter screen 113, the oil-gas mixture moves upward, and the oil is retained by the sawdust filter plate 118. The air flows between the lower top cover 116 and the upper top cover 101, and finally flows out through the twelve small holes on the lower top cover 116. Similarly, the air can also flow into the retarder in the opposite path to keep the retarder connected to the atmosphere. This kind of external automobile hydraulic retarder oil storage tank not only stores a certain amount of retarder oil, but also ensures that the retarder oil will not spray out from the retarder oil storage tank, and the structure is relatively simple and easy to install, and can be widely used in trucks equipped with hydraulic retarders.
