Description
Technical field
The present invention relates to rear axle of automobile chassis assembly, divides trailing arm suspension more particularly to a kind of applicable multi link formula
The general chassis front axle assy of multi-vehicle-type.
Background technology
Rear axle assy is made of caliper, brake disc, hub bracket, rear trailing arm, hub bearing.
Caliper, brake disc primarily serve braking action；Hub bearing connects hub bracket and tire, and tire is directly fixed
On it, hub spindle is rotated with tire；Hub bracket is to play the role of connecting together hub bearing with rear trailing arm, at the same time
Connection is not belonging to other connecting rods of chassis rear axle assy；Trailing arm connection body mounting and hub bracket afterwards.
The present invention mainly divides trailing arm suspension structure with reference to multi link formula, is limited according to chassis platform size, rationally
Design each component structural, size, formation meets the front axle assy product that multiple vehicles use, can general vehicle include
J71、J5LA。
The characteristics of multi link formula divides trailing arm suspension is as follows：
The suspension of multi link formula can not only ensure to possess certain comfort, but also since connecting rod is more, can make wheel and ground
Face as much as possible keeps vertical, as much as possible reduces the inclination of vehicle body.Maximum possible maintains the patch ground property of tire.It is manipulated
Performance and double fork arm type equal suspensions are roughly the same, and high-grade car is since space is abundant and focuses on comfort property and manipulation stability, institute
To use multi-link lever suspension fork mostly, it may be said that multi link suspension is the excellent partner of high-grade car.And trailing arm is divided to make
Overall weight it is lighter, comfort is more preferable.
Current China's automobile market has been the big market of the first in the world, volume of production and marketing be respectively completed within 2016 2811.9 ten thousand and
2802.8 ten thousand, the whole world first is continued to hold a post or title within continuous 8 years, is influenced by promoting factors such as purchase tax preferential policies, Chinese automobile in 2016
Monthly sales volume in addition to 2 months, remaining month obviously higher than same period last year, the overall developing state that is presented that both production and marketing thrive.At the same time
Automobile industry competition increasingly encourages, and new model is constantly released, and Automobile Enterprises are in order to ensure that the profitability of oneself must be good
Control cost, and multi-vehicle-type spare part in common use, can effectively amortize reduces R＆D costs, manufacturing equipment cost, simultaneously for
For the disk-like accessory of bottom, technological accumulation, the generation of reduction quality problems can also be passed through.
Existing chassis rear axle assy can not effectively adjust trailing wheel toe-in since it is configured to MacPherson type, to prevent from taking turns
Sidewall is inclined, and damping effect is general, and comfort property is up for further improving.
The content of the invention
The invention aims to provide a kind of to divide the multi-vehicle-type of trailing arm suspension general chassis using multi link formula
Rear axle assy, the rear axle assy divide trailing arm suspension structure with reference to multi link formula, are limited according to chassis platform size, rationally set
Each component structural, size are counted, formation meets the rear axle assy product that multiple vehicles use.
The object of the present invention is achieved like this, and a kind of multi link formula that is applicable in divides the chassis rear axle of trailing arm suspension total
Into the front axle assy includes brake disc, hub bearing, dust blocking tray, hub bracket, rear trailing arm, and the hub bearing is assembled to system
On Moving plate, dust blocking tray is installed to hub bearing, and in the hub bracket connection installation to hub bearing, rear trailing arm is installed to wheel
On hub holder.
The hub spindle includes flange, tire mount, keeps stent, outer ring, end cap, inner ring, steel ball；The flange
Circumferentially direction is uniformly fixed with five tire mounts, and the holding stent is arranged between outer ring and inner ring outside steel ball
Side, the outer ring are also arranged on outer ring in addition to the outer support face for being steel ball by four bolt stationary hub stents, the end cap
Front end, carries ABS harness mounting holes on end cap, the inner ring is arranged on flange front end outer side.
Trailing arm includes trailing arm main body and rubber bushing after described, and the trailing arm main body passes through three bolts and trailing wheel hub holder
Connection, the rubber bushing are the nodes being connected with car body suspension, are arranged in trailing arm body trailing end mounting hole.
The present invention has the advantages that：
1st, the present invention mainly divides trailing arm suspension structure with reference to multi link formula, is limited according to chassis platform size, rationally set
Count each component structural, size, formation meets the front axle assy product that multiple vehicles use, can general vehicle include
J71、J5LA.Each composition design of part, Sizes.
2nd, multi link formula suspension can not only ensure to possess certain comfort, but also since connecting rod is more, can make car
Wheel and ground as much as possible keep vertical, as much as possible reduce the inclination of vehicle body.
3rd, trailing arm type structure is divided make it that overall weight is lighter, comfort property is more preferable.
4th, the present invention can realize the optimum position of castor, and the anteroposterior direction power from road surface is greatly reduced, from
And improve the ride comfort and comfort when accelerating and braking.
