Recently, Allison, a global manufacturer of fully automatic transmissions, announced that it will expand its global headquarters base in Indianapolis, Indiana, USA. The project will add 205 jobs by 2013 and plans to invest US$89 million. . In Indianapolis, Allison Transmission currently has 2,500 employees. As a highly socially responsible manufacturing company, Allison has hired 50 new employees in April this year. With the phased expansion of the project, new jobs will appear one after another. By 2013, 205 new jobs will be created. In addition, the project will also help improve the transportation network needed to expand to Speedway, Indiana. The Allison Headquarters expansion project has been supported by the local government and people. Lawrence E. Dewey, chairman and chief executive officer of Allison Transmission, stated: “Allison has been in peace with Indianapolis, Indianapolis, Speedway and citizens. We have always been with them. Thanks for the support, our park in Indianapolis will grow and expand in the future, and the expansion of land will be a difficult task.The Indianapolis government decided to re-plan the tenth street that straddles our global headquarters. The solution will enable us to grow our business, expand our product offerings, and employ more staff. As a corporate member of the community, we will continue to take root here!" As a global leader in the production of fully automatic transmissions, Allison has always been committed to the development and application of new products. Includes three new fuel optimization programs, the Economic Shifting Program (SESS), Load Based Shift Program Technology (LBSS), and the Vehicle Acceleration Control Function (VAC). These new technologies can really ensure full power shifting, as well as the effective use of engine power to drive the vehicle, electronic control of the gearbox to the shift point, and early engagement of the torque converter lock-up clutch, allowing engine horsepower to The use of a torque converter is optimized to reduce fuel consumption. At present, the company is developing and testing an innovative commercial gearbox for long-distance transport vehicles. This project has been approved by the board of directors and started production. In 1915, Allison Transmission was founded by Jim Allison, one of the four founders of the Indianapolis Race. In 2007, Carlyle Group and Onex acquired Allison Transmission from General Motors. Currently, Allison has regional headquarters in China, the Netherlands, Brazil, India and Japan. It provides a full range of services through 1,500 distributors and agents in 80 countries.
Ball
Joint:
The main function of the Ball Joint is to realize the
upper and lower bounce and turn motion of the wheel.
Structure:
There are two kinds of main structure of
the ball joint: one is spherical joint combined with the whole joint, the other
is a hemispherical joint combined. Before using helical spring structure preloading
and wear compensation, now what is widely used is elastic and lubrication
synthetic resin tee which can reduce the cost and improve the maneuverability
and stability. In addition, the material and shape of the dust cover, oil type
has greatly improved, cancel the grease nozzle,of free maintenance.
Ball joint is mainly composed of an end
cover, ball pin, tee and dust cover form.
Connection
mode:
Due to the size and type of the spatial
arrangement of the Control Arm, ball joint is connected with the control arm is
as follows, bolt or rivet connection, directly pressed into the control arm and
the control arm as one. From the ball head pin development trend, now more and
more with the control arm as a whole the fixed ball pin, to meet the needs of
small space occupation, convenient loading and low cost requirements. But the
type of ball head pin of the service life of the demand is higher, so as to
avoid the abrasion of the ball head pin or a failure. The whole control arm and
the steering knuckle ball pin connection adopt 1/6~1/10 taper fitting manner.
Perforce
Requirement:
It should have sufficient swing angle, in
order to meet the requirements of wheel jumping up and down; small friction
moment is to ensure that the steering important factors and easy manipulation;
should not be caused by clearance of wheel shimmy and abnormal noise; good
sealing performance, to ensure that the ball head pin can be used in water and
low temperature environment should have the strength and durability; enough to
withstand the force and vibration, the wheel came.
Manufacturing:
For independent suspension front and rear
suspension of the ball head pin is an important safety component protection,
must be used to ensure the quality of the production process.
1)Attention to the full joint. For hot
forging, cold forging, pressing or casting method for manufacturing blank, then
cutting. Control of materials and heat treatment is a key factor.
(2) Ball pin machining way for cold forging
products is the mainstream. In the heat treatment of the material control is
the key factor, in addition to the products of conical connection type, its
size accuracy is the key factor of stable fatigue limit, need to take measures
in size control of cold forging;
(3) Polyacrylate and polyester elastomer
synthetic resin material structure with elastic effect to become the
mainstream. In this structure, need tee shape, material design measures, to
ensure the production of stable precision molding in the mold, making the fine
The degree of control is the key factor.
(4) The structure of ball joint assembly,
assembly methods are different, but most of the rolling wheel is the main way.
As to prevent the process of different products, bad products, assembly error
and so on, take corresponding measures to prevent mistakes, also used to check
the torque. Shake angle digital inspection machine, and combining them together
to set in the procedure.
