| The balance axis plays a role | It is effective to slow down the vibration of the whole vehicle, improve driving comfort, make the engine work more smooth and smooth, the balance shaft and the crankshaft together, the rotation direction of the balance shaft is opposite to the crankshaft, so that you can offset part of the jitter.
The function of the balance shaft is to make the engine run more smoothly, reduce the vibration of the car, in order to improve the overall comfort of the car, the balance shaft technology is a simple structure and very practical engine technology, it can effectively slow down the vibration of the whole vehicle and improve the comfort of driving. |
| How it works | It is through the rotary inertia force to produce a force opposite to the direction of engine vibration, so as to achieve the purpose of balancing the engine. The balance shaft usually consists of a long metal rod with both ends fixed to the engine housing. Its main part is a series of counterweight blocks which are mounted at specific positions on the balance shaft to generate a counterweight force. When the engine is running, the piston movement inside the engine produces vibration and vibration forces, and these forces are transmitted to the engine housing. The existence of a balance shaft can counteract these forces, making the engine run more smoothly |
Installation method
The utility model relates to a balance shaft assembly for an
automobile, in particular to a balance shaft assembly of an open
balance suspension. (2) Background technology The core component of
the automotive balance suspension system is the balance shaft
assembly. The balance shaft is integrated through, because the
balance shaft is integrated through, the weight of the balance
shaft assembly increases, and the economy of the vehicle decreases;
In addition, if the balance shaft assembly Angle is slightly
improper, it is easy to interfere with the drive shaft. The
integral balance shaft is a large forging, and its hot processing,
cold processing and heat treatment require special equipment, which
has led to poor performance of the balance shaft assembly, low
production efficiency and high cost. The technical problem to be
solved by the utility model is that the utility model provides a
balance shaft assembly of the broken type balance suspension with
large bearing capacity, reliable performance, simple structure,
easy production and assembly, and low cost. In order to solve the
above technical problems, the utility model comprises a support, a
balance shaft and a balance shaft shell. One end of the balance
shaft is fixed with the support, and the other end is rotationally
connected with the balance shaft shell. In order to reduce weight,
the balance shaft is provided with a blind hole in the middle. In
order to facilitate installation, reduce the intermediate
connecting parts used for installation, and further reduce the
weight of the assembly, the upper part of the support is provided
with a connecting hole for connecting with the frame, the lower
part of the support is provided with a connecting hole for
connecting with the push-down force rod, and the balance shaft
shell is provided with a spring clamping slot and a spring clamping
device. In order to improve reliability and load bearing capacity,
the balance shaft and the balance shaft housing are connected by
spherical bearings. The utility model has the advantages of compact
structure, light weight, low cost, good performance, large bearing
capacity, simple structure and convenient production and
installation. Due to the elimination of the interference point of
the original suspension, the runout of the middle and rear axle is
significantly increased, which greatly reduces the frequency of the
transaxle overload due to the limiting position, thus extending the
service life of the related components of the transaxle. Due to the
perfect match of the new practical model with the plate spring and
the rubber bearing, the impact resistance and compliance of the
vehicle are greatly improved
Improve, enhance the comfort of the occupant, reduce the
probability of damage to the cargo, improve the reliability and
life of the frame. (4)

Concrete implementation mode
A concrete embodiment, shown in Figures 1 and 2, comprises a
support 3, a balance axis 4, and a balance axis housing 9. Balance
shaft 4 is a precision forging with a blind hole in the middle. The
upper part of the bracket 3 is provided with a connecting hole for
connecting with the frame, the lower part is provided with a
connecting hole for connecting with the lower thrust rod, and the
middle part is provided with a mounting hole for a balance shaft 4,
one end of the balance shaft 4 is fixed with the bracket 3, and the
other end is connected with the balance shaft housing 9 through the
ball bearing 13. The balance shaft shell 9 is provided with a
spring clamping groove and a spring clamping device, and the outer
end of the balance shaft shell 9 is provided with a shell cover 18.
The mounting method of the utility model takes the bracket 3 as the
assembly matrix, first spreads the bonding glue in the inner hole
of the bracket 3, then assemps the balance shaft 4 in place, and
drives the cylindrical pin 19 into position after the glue is
solidified. Then install the type ring 6 on the bearing oil seal
cover 8, and then install the inner ring of the seal ring 5, the
bearing oil seal cover 8 and the spherical bearing 13 in turn on
the balance shaft 4; Insert the outer ring of spherical bearing 13
respectively into the two bearing holes of the balance shaft
housing 9, and then insert the shaft sealing ring 7 into the shaft
sealing ring hole, and then install the balance shaft housing 9 on
the balance shaft 4, and then install the spacer bushing 17,
positioning washer 16 and the spherical bearing 13 inner ring, and
fix the bearing block 15 and balance shaft 4 with bolt 14 after
installing the inner ring. After the above assembly is completed,
apply uniform sealant on the outer end face of the balance shaft
shell 9, and fix the shell cover 18 and the balance shaft shell 9
with bolt 11 to achieve seal. After the assembly is completed, add
lubricating oil into the oil hole to achieve lubrication, open the
air hole when refueling, tighten the hexagon head bolt 10 and the
cone thread hexagon plug 12 to keep the seal. The utility model is
used in pairs, respectively installed on both sides of the frame,
so that there is a certain distance between the two balance axles
4, forming a broken open structure, and will not interfere with the
automobile drive shaft. After the utility model is loaded, the
plate spring is assembled in the clamping groove of the balance
shaft shell 9, and then the screw bolt 2 and the flat washer 1
clamp the plate spring.
