Damping turns to the carrying bridge
The utility model relates to a kind of damping of carrying and turns to the carrying bridge, can assist a kind of damping of carrying to turn to vehicle bridge when especially automobile is heavily loaded.
Exploitation upgrading along with China's autotruck, supporting with it heavy vehicle bridge had also had continuous development innovation in recent years, one vapour, 457 bridges, the output cumulative year after year of the Steyr bridge of 460 bridges of Second Automobile Works, heavy vapour and benz wheel limit, north bridge is subjected to user's favor.The car load of heavy goods vehicles is arranged also from initial diaxon (forward and backward bridge) and is developed into three of today (before, during and after bridge), four (two propons,, back axle).The multiaxis bridge can increase bearing capacity, but has strengthened operating cost, has particularly increased unnecessary energy resource consumption and resource consumption to the light industrial goods transport vehicle with when the empty wagons.In order to overcome above-mentioned deficiency and defective, a kind of a kind of auxiliary carrying bridge that can be under the situation that does not increase the automobile number of axle of market in urgent need.Therefore, auxiliary carrying bridge is used and is given birth to, as bend pipe bridge, the straight tube bridge that generally uses on the market.
Though auxiliary carrying bridge is widely used on automobile, what body of a bridge structure all adopted is the form of steel plate punching press welding and steel pipe bending and forming, and its major defect: 1, body of a bridge intensity is low, easy deformation fracture in the process that vehicle operating is impacted.2, can not turn to car, produce car resistance, tire formation traction deviation is usually accelerated wear on tyres even the axle assembly torsional deflection is scrapped, and therefore uses unsatisfactory.
Summary of the invention
In order to solve the shortcoming that existing suspension-type floating axle can not follow-up steering, the utility model proposes damping and turn to the carrying bridge.
Technical conceive: utilize the structure of existing propons, one group of damping spring on the intermediate rod of propons dress repacks damping into and turns to the carrying bridge.Utilize the shock damping action of spring to arrange damping and turn to the craspedodrome of carrying bridge and turn to, thereby avoided not having the wigwag motion of steering hardware and the vehicle shake and the tire abrasion that cause.
Technical scheme: damping turns to the carrying bridge, comprises the front axle assy of being made up of H-girder, brake assembly, tierod, knuckle assembly, Hub assembly, it is characterized in that: the installed inside of intermediate rod has compression spring.
Beneficial effect: utilize the structural I-beam of propons to solve body of a bridge strength problem; The utility model is that one group of damping spring is installed on intermediate rod, by the elastic force effect of damping spring, realizes and solve the drawback that auxiliary carrying bridge can not follow-up steering.Reduced the abrasion of tire.Reduce operation cost, improved economic benefit.

The specific embodiment
Shown in Fig. 1,2, it is as follows to further describe the utility model: damping turns to the carrying bridge, comprise the front axle assy of being made up of H-girder 1, brake assembly 2, tierod 5, knuckle assembly 4, Hub assembly 2, the installed inside of tierod 5 has compression spring 7.
As shown in Figure 2, the installation of compression spring is achieved in that and is fixed with two flaps 6 on H-girder 1, and compression spring 7 is enclosed within on the tierod 5, and the outer end of compression spring is spacing by two flaps, 6 corresponding end faces.
