[0002] The main role of balance shaft is to reduce the vibration of engine, reduce noise, improve the comfort of driving, and its working principle is: balance shaft is usually equipped with eccentric weight, and rotates synchronously with crankshaft. The counter-vibration force generated by eccentric weight balances the vibration force of other parts of engine in operation, thereby reducing the vibration of engine.

[0003] At present, automobile balance shaft is usually installed at the front of engine or on the back of crankshaft, and balance shaft mounting seat is needed in the installation process. However, errors are inevitable in the production process of balance shaft mounting seat, and the errors will be larger when assembling multiple components, which will cause errors in the height between the two mounting seats and affect the use of balance shaft.

[0004] Publication No. CN221347741U proposes a new energy automobile balance shaft support. When the height of the mounting seat needs to be adjusted, adjusting washers can be added at the bottom end of the mounting plate. The thickness of the adjusting washer is fixedly set, and multiple adjusting washers can be stacked together according to the required height, so as to compensate for the height error of the support body in use. However, this structure needs to manually disassemble and install the washers when compensating for the height error of the two support bodies, and it is not convenient to stack and install multiple washers, so the use effect of the balance shaft support needs to be further improved.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0031] like Figures 1 to 3 As shown, a car balance shaft mounting bracket includes a support body 1, a first base 2, a fixing plate 21, a screw 31, a drive assembly 32, a guide roller 33, a slider 34, a telescopic rod 36, and a second base. The first base 2 has a mounting cavity formed therein.

[0032] The fixing plates 21 are symmetrically arranged on the first base 2 and the second base, and the fixing plates 21 are provided with fixing bolts (not shown in the figure);

[0033] The screw 31, drive assembly 32 and telescopic rod 36 are all located in the mounting cavity. One end of the screw 31 extends beyond the first base 2 and the screw 31 is connected to the drive assembly 32 (specifically, the drive assembly 32 uses gear transmission, which is a prior art principle and will not be described, and is not labeled in the figure).
