SUMMERY OF THE UTILITY MODEL
To the problem in the background art, the utility model provides a heavily block mounting structure of suspension before driver's cabin to among the solution prior art, the sub-unit connection part of suspension is more before the driver's cabin of heavily blocking, and the relation of connection is complicated, and production efficiency is low, the poor problem of structural rigidity.
The utility model aims at realizing through the technical scheme, it is including:
a mounting structure of a front suspension of a heavy truck cab comprises a left suspension, a right suspension, a left frame longitudinal beam, a right frame longitudinal beam and a bumper; left side suspension is connected with left solebar, right side suspension with right solebar is connected its characterized in that: the left suspension comprises a left lower support and a left shock absorber, the main body of the left lower support is a plate-shaped structural body, a first hinge shaft is arranged on the left side surface of the main body of the left lower support, a plurality of first connecting holes used for being connected with the bumper are formed in the front end surface of the main body of the left lower support, a first hinge lug is arranged at the lower end of the left shock absorber, the main body of the left lower support is connected with the left frame longitudinal beam through a bolt, and the first hinge shaft is hinged to the first hinge lug;
the right suspension comprises a right lower support and a right shock absorber, the main body of the right lower support is a plate-shaped structural body, a second hinge shaft is arranged on the right side surface of the main body of the right lower support, a plurality of second connecting holes used for being connected with the bumper are formed in the front end surface of the main body of the right lower support, a second hinge lug is arranged at the lower end of the right shock absorber, the main body of the right lower support is connected with the right frame longitudinal beam through a bolt, and the second hinge shaft is hinged with the second hinge lug;
the two ends of the bumper are respectively arranged on the front end surface of the left lower bracket main body and the front end surface of the right lower bracket main body, and the left end of the bumper is connected with the left lower bracket through a bolt; the right end of the bumper is connected with the right lower bracket through a bolt.
Preferably, the left lower support and the right lower support are both castings.
Due to the adoption of the technical scheme, the utility model discloses following advantage has: because the bumper bracket is cancelled, the left lower bracket and the right lower bracket are directly connected with the left frame longitudinal beam and the right frame longitudinal beam respectively, and the bumper is directly connected with the two lower brackets, the number of parts is reduced, the installation position is reduced, and the production efficiency is improved; meanwhile, the reliability of connection is greatly improved due to the reduction of the connection parts; as optimization, the left lower support and the right lower support are both castings, and the strength and the rigidity of the front suspension joint of the cab are greatly improved.
