[0030] First embodiment
[0031] This embodiment provides a modular wheeled tractor diesel engine oil pan 100, referring to Figure 1 and Figure 2 As shown, it includes an oil sump body 110 and a pair of side link plates 120 detachably connected to the oil sump body 110 .
[0032] like Figure 1 As shown, the oil pan body 110 includes opposite front and rear ends, and a flywheel housing connecting surface 111 is provided at the front end; a pair of side chain plates 120 are symmetrically arranged on both sides of the oil pan body 110, and the pair of side chain plates 120 extend backward beyond the rear end to form a chassis connecting surface 121.
[0033] The utility model modularizes the diesel engine oil pan 100 for wheeled tractors and divides it into three parts. The oil pan body 110 adopts a unified specification, which reduces the difficulty of mold opening and production costs, and the two side chain plates 120 can be processed into different specifications, so as to adapt to various types of chassis and have better versatility. Figures 2 to 4 , which shows a schematic diagram of the connection between the oil pan body 110 and different types of side chain plates 120 .
[0034] Furthermore, if Figure 1 As shown, a bracket connection surface 112 is provided on both sides of the oil pan body 110. The bracket connection surface 112 is provided near the rear end. The bracket connection surface 112 is provided with a plurality of threaded holes 113 for installing the side chain plate 120. The side chain plate 120 is detachably connected to the oil pan body 110 through the threaded holes 113.
[0035] The bracket connection surface 112 is provided with a plurality of bosses 114 protruding laterally, the bosses 114 are arranged along the height direction of the oil pan body 110, and the plurality of bosses 114 are arranged at intervals along the length direction of the oil pan body 110; a plurality of threaded holes 113 are distributed on the top surface of the bosses 114, and the plurality of threaded holes 113 on each boss 114 are arranged in a row along the height direction of the oil pan body 110. Since the side chain plate 120 and the oil pan body 110 are connected by threads, the force at the connection is relatively large, and the periphery of the threaded holes 113 is prone to cracking. The bosses 114 increase the firmness of the connection and better disperse the stress. At the same time, the grooves formed between the bosses 114 can increase the heat dissipation effect.
[0036] Optionally, the plurality of threaded holes 113 are arranged in a matrix, and the threaded holes 113 at the same height on the plurality of bosses 114 are arranged in a row. The threaded holes 113 arranged in a matrix are conducive to adjusting the position of the side chain plate 120. Different threaded holes 113 can be selected for connection with side chain plates 120 of different shapes, so as to be installed in a suitable position.
[0037] The flywheel housing connection surface 111 extends to both sides to form two side spokes 115. In the case of existing flywheel housings on the market that are only connected by the middle screw hole, the lower part of the flywheel housing is easily torn. The design of the two side spokes 115 increases the contact area between the flywheel housing and the oil pan body 110. At the same time, the increased area can be provided with additional connection bolts, further strengthening the connection strength between the flywheel housing and the oil pan body 110.
[0038] Furthermore, if Figure 1 As shown, an inner cavity 116 is formed inside the oil pan body 110, and a support plate 117 is arranged inside the inner cavity 116. The support plate 117 is arranged along the width direction of the inner cavity 116 and connected to the side walls of the oil pan body 110. Since the side chain plates 120 are installed on both sides of the oil pan body 110, an outward pulling force will be formed under the action of gravity. The support plate 117 reinforces the oil pan body 110 from the inside, increasing the overall strength and stability. There are multiple support plates 117, and the multiple support plates 117 are arranged at intervals along the length direction of the inner cavity 116.
[0039] Second embodiment
[0040] This embodiment provides a modular diesel engine oil pan 100 for a wheeled tractor, which is improved on the basis of the first embodiment.
[0041] like Figure 5 As shown, an inwardly arched groove 118 is provided at the bottom of the oil pan body 110, and the arch groove 118 is provided along the length direction of the oil pan body 110, extending from the front end to the rear end. Since the heights of the front steering / drive shaft sleeves of the gearboxes of different tractors relative to the center of the crankshaft are different, the design of the arch groove 118 can better adapt to various chassis, and at the same time, the arch groove 118 can also improve the bending moment resistance of the oil pan body 110.
[0042] Two longitudinal reinforcing ribs 1191 are disposed at the bottom of the oil pan body 110 , and the two longitudinal reinforcing ribs 1191 are disposed along the two side edges of the arch groove 118 and extend from the front end to the rear end. The longitudinal reinforcing ribs 1191 can further enhance the moment resistance of the oil pan body 110 .
[0043] At the same time, a plurality of transverse reinforcing ribs 1192 are also provided at the bottom of the oil pan body 110. The transverse reinforcing ribs 1192 are provided along the width direction of the oil pan body 110 and extend from the longitudinal reinforcing ribs 1191 to the boss 114. The longitudinal reinforcing ribs 1191 can improve the strength of the bottom of the oil pan body 110 and better overcome the torque applied by the side chain plate 120 to the bottom of the oil pan body 110 under gravity.
[0044] In summary, the embodiment of the utility model provides a modular diesel engine oil pan 100 for wheeled tractors, which includes an oil pan body 110 and a pair of side chain plates 120 detachably connected to the oil pan body 110; the oil pan body 110 includes a front end and a rear end opposite to each other, and the front end is provided with a flywheel housing connection surface 111; the pair of side chain plates 120 are symmetrically arranged on both sides of the oil pan body 110, and the pair of side chain plates 120 extend backward beyond the rear end to form a chassis connection surface 121. The oil pan body 110 adopts a unified specification, which reduces the difficulty of mold opening and production cost, and the side chain plates 120 can be processed into different specifications, so as to adapt to various types of chassis and have better versatility.
[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
