What is a trailer crank handle?
The trailer crank handle is the main rotating mechanism of the engine. It is responsible for
transforming the up and down reciprocating motion of the piston into its own circular motion, and
usually what we call the engine speed is the speed of the trailer crank handle. The trailer crank
handle bears the force transmitted from the connecting rod and converts it into torque to output
through the trailer crank handle and drive other accessories on the engine to work. It is subjected
to the combined action of the centrifugal force of the rotating mass, the periodically changing gas
inertial force and the reciprocating inertial force, so that the trailer crank handle bears the bending
torsional load. Therefore, thetrailer crankhandle is required tohavesufficient strengthand rigidity,
and the surface of the journal should be wear-resistant, work uniformly, and have good balance.
Composition of trailer crank handle.
The trailer crank handle is mainly composed of the front end (or free end) of the trailer crank
handle, the connecting rod journal, the main journal, the trailer crank handle, the balance weight
and the rear flange of the trailer crank handle (or the power output end). The main journal is
installed on the cylinder body, the connecting rod neck is connected with the big end hole of the
connecting rod, and the small end hole of the connecting rod is connected with thecylinder piston.
It is a typical trailer crank handle slider mechanism.
The role of trailer crank handle
The function of the trailer crank handle is to convert the reciprocating linear motion of the piston
into its own rotary motion to output power to the outside. During the working process of the
engine, thepiston is burnt and exploded by themixed compressed gas, pushing the piston tomove
in a straight line, and transmits the force to the trailer crank handle through the connecting rod,
and the linear motion is converted into a rotary motion by the trailer crank handle. Therefore, the
rotation of the trailer crank handle is the power source of the engine and the power source of the
entire mechanical system.
The working principle of trailer crank handle
The working principle of trailer crank handle is to convert the thermal energy generatedwhen the
fuel is burned into mechanical energy, and the reciprocating motion of the piston is changed into
the rotary motion of the trailer crank handle through the connecting rod to output power to the

2. outside. The trailer crank handle consists of the body set (mainly including the cylinder block, the
trailer crank handle box, the oil pan, the cylinder liner, the cylinder head and the cylinder head
gasket and other fixed parts), the piston connecting rod set (mainly including the piston, piston
ring, piston pin and It consists of three parts: connecting rod and other moving parts) and trailer
crank handle flywheel assembly (mainly including trailer crank handle, flywheel, torsion damper,
balance shaft and other mechanisms).
Therearethreetypes of trailer crankhandles: double trailer crankhandle, double rocker and trailer
crank handle. A trailer crank handle that can do circular motion is called a trailer crank handle, and
a rocker that can only swing within a range of less than 360° is called a rocker. The double trailer
crank handle means that the trailer crank handle drives the trailer crank handle to rotate, and the
double rocker is the rocker that drives the rocker to swing. Trailer crank handle rocker mechanism,
when the trailer crank handle is the active part, thetrailer crank handle makes a circular motion to
drive the rocker to swing; when the rocker is the active part, the rocker swings to drive the trailer
crank handle to make a circular motion.
The importance of trailer crank handle
The trailer crank handle is an important part of the automobile engine. Its function is to convert
the gas force transmitted by the piston and connecting rod into torque, and convert the piston's
linear motion into rotarymotion, which is used to drive the transmission system and engine of the
automobile. The valve mechanism and other auxiliary devices. To put it bluntly, it is the power
output element on the car. The force of the trailer crank handle is extremely complicated. It works
under the combined action of periodically changing gasforce, inertial force and moment of force,
and bears alternating loads of bending and torsion. Therefore, the trailer crank handle is required
to have sufficient fatigue strength and stiffness to resist bending and torsion; the journal should
have a largeenough bearing surface and wearresistance.
The trailer crank handle is generally die-forged from medium-carbon steel and medium-carbon
alloy steel such as 45, 40Cr, 35Mn2, and the surface of the journal is high-frequency hardened or
nitrided, and finally processed. In order to improve the fatiguestrength of the trailer crank handle
and eliminate stress concentration, the surface of the journal should be shot peened, and the
rounded corners should be rolled. It should be noted that the nitrided trailer crankhandle must be
re-nitrided after grinding, otherwise the trailer crank handle may be broken.
The trailer crankhandle is basically composed of several unit cranks. A trailer crankhandle pin, two
left and right trailer crank handle arms and two left and right main journals constitute a unit crank.
The relative position or arrangement of the cranks depends on the number of cylinders, the
arrangement of the cylinders, and the order of the engine's work.
The trailer crank handle is a moving part that rotates at high speed, so its balance is extremely
important. The balance weight set on the trailer crank handle arm of the trailer crank handle can
only balance the rotating inertia force and its moment, while the balance of the reciprocating
inertia force and its moment requires a special balancing mechanism, which is generally added to

3. the engine. Two balance shafts, its rotation direction is opposite to the trailer crank handle, and
the speed is twice that of the trailer crank handle, so that the reciprocating inertia force and
moment generatedwhen the trailer crank handle rotatescan be balanced.
In theory, the inline six-cylinder engine has the least vibration and the best running smoothness.
Generally, the balance of the trailer crank handle can be achieved without the use of a balance
shaft. Therefore, the vast majority of truck engines on the market adopt an in-line six-cylinder
arrangement.
