Driver introductions Bridge
1. Features:
Drive Bridge at the end of powertrain, and the basic function of which is to increase
came from the drive shaft or transmission of torque, and a reasonable distribution of power
to the left and right driving wheel, and also bear in the role of the frame or the road and
Legislative body between the vertical, horizontal and vertical of power. Driven by the
general bridge reducer, differential, wheels, transmission and drive axle housings and other
components.
2. The bridge design driver:
1Drive bridge design should meet the following basic requirements:1. Choice of
the reduction ratio should be able to guarantee that vehicles have the power and the best fuel
economy.
2. Dimensions small to ensure that the necessary ground clearance. 3.
Transmission gears and other pieces of work stable and noise.
4. Under various load and speed with high transmission efficiency. 5. Guarantee
sufficient strength, rigidity conditions, should strive for quality small, particularly unsprung
mass should be as small as possible to improve vehicle ride comfort.
6. Oriented suspension and coordination of movement, to the drive axle, and the
steering mechanism should be coordinated with campaigns.
7. Simple structure, and processing of, and easy to manufacture, enables easy
adjustment.
3. Drive Bridge Category
3.1 non-driving axle-disconnect
Disconnect-general non-driving axle, simple structure, low cost, reliable, widely used in a
variety of truck, bus and the bus, in the majority of off-road vehicles and some cars also
adopt this structure. Their specific structure, in particular the shell structure while the
bridge is not the same, but there is one common characteristic is that Shell is a bridge
support in the drive wheel about the rigid hollow beam, and the half-axle gear transmission
components, such as installation of one of them. Then the whole drive axle, drive shaft
driven wheel and some are in unsprung mass, larger vehicles unsprung mass, which is one
of its shortcomings.
Drive Axle size depends primarily on the outline of the main types reducer. In the tire size
and drive underneath the minimum ground clearance has been determined by circumstances,
it defines the diameter of the driven gear reducer size. Ratio of a given condition, if the
single-stage reducer can not meet the requirements of ground clearance, with the dual-class
structure. In the two-stage reducer, the two usually on a main gear reducer shell reducer, can
also slow gear as a second-class round-reducer. The round-reducer: In order to improve
cross-country motor vehicle ground clearance, can be a spur gear consisting of round-gear
reducer initiatives under its follower of the vertical top gear; buses to reduce vehicle height
and the center of mass of train floors height, so as to enhance stability and the convenience
of the passengers get on and off, can be round-gear reducer initiatives under its vertical
driven gear beneath some double-decker bus in order to further reduce the compartment
floor height in a round-Gear reducer At the same time, the main reducer and differential
assembly also moved to the driver's side wheel.
In a few large-scale high-speed bus engine, multi-bridge drive vehicle and ultra-heavy laden
car, and sometimes used for the worm reducer, it not only has the quality of small, compact
size of circumstances can be large and transmission ratio Smoothing the merits of silent
work, and the overall layout of the car is very convenient.
3.2-drive axle disconnect
Disconnect-drive axle different from the non-driving axle-disconnect the obvious
characteristics of a connection is that the former does not drive the wheels about the rigidity
of the overall casing or beam. Disconnect drive bridge is the bridge sub-shell, and can be
done between the relative motion, such as off-the bridge. In addition, it always match with
independent suspension, it is also known as the independent suspension bridge driver. The
middle of this bridge, the main reducer and differential, are mounting in the frame beams
inside or on the floor, or backbone of the frame. Lord reducer, and the driveshaft and
differential wheel drive part of the quality of transmission quality on all spring. As both
sides of the drive wheel independent suspension can be used to the site relative to each other
frame for the upper and lower compartments or swing, with a corresponding demand on the
drive wheel and the gear casing or casing for the corresponding swing.
The hoisting of the type of vehicle assembly and elastic damping device components and
characteristics of the work is to determine vehicle ride comfort of the main factors, and the
quality of auto parts spring the size of their ride also have a marked impact. Disconnect-
drive axle unsprung mass smaller, independent suspension with the match, which drive the
wheels of contact with the ground and on all-terrain better adaptability, which can greatly
reduce car running on uneven road vibration and the tilt train, travelling to the vehicle's ride
and the average driving speed, reducing the wheels and axles on the dynamic load and parts,
increasing its reliability and service life. However, due to disconnect the drive Bridge and
the independent suspension with the match of the complex structure, this structure is mainly
seen on the ride comfort of the higher part of sedans and some off-road vehicle, and the
latter more than a light following riders Bridge drive vehicles or heavy-duty off-road
vehicle.
3.3 Bridge over drive layout
In order to improve loading and adoption of some medium - and heavy-duty vehicles and all
over the use of off-road vehicles are driven more bridge, and often used 4,6 × 4 × 8 × such
as 6,8-driven type. Multi-Bridge driver in the circumstances, the driving force at the drive
actuator pass in the way the two bridges. The two corresponding power transmission, the
Multi-Bridge drive vehicle driving axle layout patterns into non-hollow and hollow. The
former in order to force the pass at the drive actuator bridge to the actuator from the drive
axle by its own dedicated power transmission drive shaft, not only to increase the number of
drive shaft, and the cause of the drive axle Bridge parts in particular Shell, and other major
parts Semiaxle not universal. On the 8 × 8 vehicle, this non-drive-through bridge is even
more inappropriate, but also a difficult layout.
In order to solve the above problems, modern bridges are used in cars driven through the
drive axle-type layout.
