Disclosure of Invention
The utility model aims at providing a cylinder body of integrated generator support, it can avoid when dismantling the generator, and generator fastening bolt takes place to interfere with the girder, makes the generator accomplish to dismantle on whole car, needn't tear down the generator again to the engine from the cabin earlier to shorten maintenance duration, reduce cost of maintenance.
The utility model discloses a cylinder body of an integrated generator bracket, which comprises a cylinder body and a generator bracket integrated on the cylinder body, wherein the generator bracket is close to one side of a girder of a whole vehicle; the generator support is provided with two support lugs for mounting a generator, each support lug is provided with a bolt through hole which is transversely penetrated, and a weight reduction window is arranged at the right part of each bolt through hole; the method is characterized in that: a notch is formed in the left part of the bolt through hole of the support lug, and the right end of the notch is communicated with the weight reduction window; the support lug of the generator support is matched with the hanger of the generator and is connected and fastened through a fastening bolt; the width L4 of the notch is greater than the diameter of the fastening bolt.
Further, the width L4 of the notch is larger than the diameter 1mm of the fastening bolt.
The utility model has the advantages that:
because the left part of the bolt through hole arranged on the support lug of the generator bracket is provided with the notch, and the width L4 of the notch is larger than the diameter of the fastening bolt, when the generator needs to be disassembled, the fastening bolt does not need to withdraw from the distance of L3 (namely the distance that the fastening bolt needs to withdraw when the generator is disassembled), and only needs to withdraw from the distance of L5 (namely the distance that the fastening bolt withdraws to the weight reduction groove), the fastening bolt can be taken out from the radial direction of the bolt through hole without interfering with the girder of the whole vehicle, so the generator can be taken off from the whole vehicle; the generator is disassembled on the whole vehicle, so that the operation that the engine needs to be disassembled from the engine room firstly when the generator is disassembled on the cylinder body of the integrated generator support is avoided, the after-sale maintenance time is shortened, and the maintenance cost is reduced.

In the figure:
1-existing cylinder, 11-existing generator support, 12-existing support lug, 13-existing lightening window, 14-existing generator, 15-existing generator hanger and 16-existing fastening bolt; 17-the existing whole vehicle girder;
2-cylinder block, 21-generator support, 22-lug, 23-weight reduction window, 24-generator, 25-generator hanger and 26-fastening bolt; 27-girder of whole car, 28-notch.
Detailed Description
The present invention will be further described with reference to the prior art with reference to the accompanying drawings.
Referring to fig. 1 and 2, an existing generator support 11 integrated with an existing cylinder block 1 is provided, the generator support has two existing support lugs 12, in order to ensure that the existing generator support has sufficient strength and good NVH performance, a span L1 between the two existing support lugs 12 is generally greater than 50mm, and in consideration of avoiding the problem of excessive local wall thickness of the cylinder block, the two existing support lugs are respectively provided with an existing weight reduction window 13. With the requirement of light weight of the whole vehicle and the engine, the space of the engine compartment is smaller, so that the distance L2 between the existing fastening bolt 16 of the existing generator 14 and the existing whole vehicle girder 17 is smaller, and the L2 is generally 25mm at the minimum. However, when the existing generator needs to be disassembled, because the length L3 of the existing fastening bolt 16 of the existing generator exiting from the existing generator hitching leg 15 is much larger than L2, when the existing generator needs to be replaced or maintained, the existing fastening bolt of the existing generator interferes with the girder of the existing whole vehicle, so that the existing fastening bolt of the existing generator and the existing generator cannot be disassembled on the whole vehicle. To accomplish the existing generator disassembly, the entire engine must first be removed from the nacelle, which results in increased maintenance time and costs. The utility model discloses this problem that the cylinder body to current integrated generator support exists provides a cylinder body of integrated generator support.
Referring to fig. 3 and 4, the cylinder body of the integrated generator bracket comprises a cylinder body 2, a generator bracket 21 integrated on the cylinder body, wherein the generator bracket 21 is close to one side of a girder 27 of the whole vehicle; the generator support 21 is provided with two support lugs 22 for mounting a generator 24, the support lugs 22 are provided with bolt through holes which are transversely penetrated, and the right parts of the bolt through holes are provided with weight reducing windows 23; the method is characterized in that: a notch 28 is formed in the left part of the bolt through hole of the support lug 22, and the right end of the notch is communicated with the weight-reducing window 23; the support lug 22 of the generator support is matched with a hanger 25 of a generator and is connected and fastened through a fastening bolt 26; the width L4 of the notch 28 is greater than the diameter of the fastening bolt 26.
The width L4 of the notch 28 is greater than the diameter of the fastening bolt 26 by 1 mm.
Because the left part of the bolt through hole of the support lug is provided with the notch, and the width L4 of the notch is larger than the diameter of the fastening bolt, when the generator needs to be disassembled, the fastening bolt does not need to withdraw from the distance of L3 (namely the distance that the fastening bolt needs to withdraw when the generator is disassembled), and only needs to withdraw from L5 (namely the distance that the fastening bolt withdraws to the lightening groove), the fastening bolt can be taken out from the radial direction of the bolt through hole, and the distance between the fastening bolt and the girder of the whole vehicle is L6 more than 0 at the moment, so that the generator can be taken off from the whole vehicle; the generator is disassembled on the whole vehicle, so that the operation that the engine needs to be disassembled from the engine room firstly when the generator is disassembled on the cylinder body of the integrated generator support is avoided, the after-sale maintenance time is shortened, and the maintenance cost is reduced.
