Embodiment Construction

[0014] Such as figure 1 shown.

[0015] A double-fixed heavy-duty balance shaft assembly, including a symmetrically arranged bracket 1, a half shaft 2 passes through the bracket 1 and is provided with a bearing hub 3, and the symmetrical bracket 1 is connected as a whole through a connecting plate 4 under the bracket 1, and used The bolt 5 is fixed, and a groove 7 is longitudinally arranged under the bracket 1, and a boss 6 is arranged on the top of the connecting plate 4. tight.

[0016] In the installation method of the present invention, the bracket 1 is used as the parent body, the half shaft 2 is pressed into the bracket 1 with interference, and the bearing hub 3 is assembled in place, and then the left and right brackets 1 are combined with the connecting plate 4 to carry out the groove 7 and Boss 6 has an interference fit and can be compressed with bolt 5 .

Abstract

The invention provides a double-fixed type heavy balance shaft assembly, comprising supports which are symmetrically arranged, wherein a semi-shaft passes through a support and is provided with a bearing hub, the symmetrical supports are connected into a whole through a connecting plate below the supports and are fixed through bolts, a groove is longitudinally formed below each support, a lug boss, corresponding to each groove, is arranged on the connecting plate, and the groove and the lug boss are in interference fit and are finally fixed and compressed through bolts. According to the invention, because the longitudinal grooves below the supports and the corresponding lug bosses on the connecting plate are longitudinally arranged, the displacement of the connecting plate is prevented, and the breakage of the bolts is further prevented; by virtue of the limiting and fixing effects of the grooves and the lug bosses as well as the fixing and compressing effects of the bolts, a double-fixed type structure is formed, thereby meeting the carrying capacity and ensuring the reliable stability; and meanwhile, the grooves and the lug bosses are in interference fit to play a positioning role and are formed into an organic whole through interference fit, thereby meeting the performance and also facilitating installation.

Description

technical field [0001] The invention relates to the field of heavy-duty vehicle engineering, in particular to a double-fixed heavy-duty balance shaft assembly. Background technique [0002] The space of the drive shaft of the original balance shaft assembly is insufficient, and the weight of the whole vehicle is heavy, which is mainly reflected in several aspects: [0003] 1. Adopt the universal connecting shaft structure, which meets the limited carrying capacity and the narrow movement space of the transmission shaft; [0004] 2. Adopting the common connecting shaft structure, considering the overweight situation, the load-bearing requirements for the balance shaft assembly are increased, and the weight of the balance shaft assembly with the corresponding structure is overweight. [0005] The application numbers are: 201310040141, 2013200579157, 2013205993859, 2013205919140, 2010200038167. They are connected by lower beams or connecting plates, and fixed by bolts or hoops...
