Abstract
The utility model relates to a gear case cover of a heavy-duty car. The gear case cover of the heavy-duty car is more reasonable in structure, high in structural rigidity, and light. The gear case cover of the heavy-duty car is characterized in that a bearing seat is arranged on one side of the upper portion of the case cover, an outer cover part is arranged on the other side of the case cover, a circle of connecting holes is formed in the top of the bearing seat, the section of the outer cover part is arc-shaped, and reinforcing ribs are arranged between the beating seat and the outer cover part. Preferably, the reinforcing ribs are two parallel reinforcing ribs which are in the same shape, and the reinforcing ribs extend to the top of the bearing seat from the top surface of the outer cover part. The outer edge of the gear case cover is oval, and a circle of connecting through holes is formed in the periphery of the outer edge of the gear case cover.
Description
Technical field
The utility model relates to a kind of improvement of cover structure, particularly a kind of heavy-duty car gear-box case lid.
Background technique
Along with China's fast economic growth, China's heavy-duty car industry is also greatly developed, case lid as the heavy-duty car gear-box, guaranteeing the sealing of gear-box, conduct and disseminate the heat from gear-box, Support Gear axle box bearing and transmission shaft also guarantee that the transmission of transmission system is stable, and as the part of gearbox-case body, play isolated and reduce the function from the gear-box interior noise.And existing cover structure material use is insufficient, case lid rigidity deficiency, yielding, manufacture reject rate higher, car load noise and travelling comfort descend.
The model utility content
For deficiency of the prior art, the utility model aim to provide a kind of structure more rationally, high, the light-weighted heavy-duty car gear-box of structural rigidity case lid.
In order to address the above problem, this kind of heavy-duty car gear-box case lid is characterized in that: top one side of this case lid is provided with bearing support, opposite side is the outer cover cap, the top of bearing support is provided with a circle attachment hole, and the section of outer cover cap is arch, between this bearing support and sheath portion, is provided with stiffening rib.
Preferably, described stiffening rib is two strips stiffening ribs identical and parallel to each other, and this stiffening rib extends to the top of described bearing support from the end face of described outer cover cap.
More preferably, this gear-box case lid outer rim ovalize, and this outer rim be circumferentially with a circle connecting through hole.
The beneficial effects of the utility model are: this kind of gear-box cover structure, guarantee under enough rigidity of support prerequisites, reduce unnecessary material, outer covering, according to bionics principle, adopts the fishbone structure, surface is along oblique protuberance, be provided with stiffening rib between bearing support and case lid, under the prerequisite that does not increase quality and cost, increase the part rigidity, reduce the car load noise, enhance product performance.
The accompanying drawing explanation
The structural representation of facing that Fig. 1 is heavy-duty car gear-box case lid of the present utility model;
The plan structure schematic diagram that Fig. 2 is Fig. 1;
Fig. 3 is along the sectional structure schematic diagram of AA line in Fig. 2;
Fig. 4 is along the sectional structure schematic diagram of BB line in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1 to Fig. 4, this kind of heavy-duty car gear-box case lid, the outer rim ovalize of this gear-box case lid, and upwards be provided with a circle connecting through hole week of this outer rim, on the top of case lid, one side is provided with bearing support 1, and opposite side is outer cover cap 3, bearing support 1 adopts the non-wall thickness design that waits, its top is provided with a circle attachment hole, and the section of outer cover cap is arch, is about to the outer cover cap and is optimized for fishbone shape surface elevation structure by more smooth face.Be provided with stiffening rib 2 between this bearing support and sheath portion.This stiffening rib 2 is two strips stiffening ribs identical and parallel to each other, and this stiffening rib extends to the top of described bearing support 1 from the end face of outer cover cap 3.
The case lid of this kind of new structure, the case lid bottom is the connecting flange structure be connected with casing, and bearing support and outer covering are arranged on adpting flange, optimize bearing block structure, guarantee to reduce unnecessary material under enough rigidity of support prerequisites, outer covering is according to bionics principle, adopt the fishbone structure, surface, along oblique protuberance, is provided with stiffening rib between bearing support and case lid, under the prerequisite that does not increase quality and cost, increase the part rigidity, reduce the car load noise, enhance product performance.
