The invention provides a rear independent suspension structure for a heavy vehicle, which is used for connecting a frame and a hub reduction gear of the vehicle and comprises two symmetrical independent suspension units and a transverse stabilizer bar assembly for connecting the two independent suspension units, and each independent suspension unit is of a double-control-arm structure. The two sides of the long shaft end of the upper control arm are rotationally connected with the frame, one side of the long shaft end of the lower control arm is fixed to the frame through a torsion rod spring, and the other side of the long shaft end of the lower control arm is rotationally connected with the frame. Short shaft ends of the upper control arm and the lower control arm are rotatably connected with a wheel edge connecting shaft. According to the rear independent suspension structure, the double-control-arm structure is adopted, each of the upper control arm and the lower control arm is of a symmetrical trapezoidal structure, the control arms are formed through forging and assembled in a split mode, cost is saved, production efficiency is improved, the overall universality of the rear independent suspension structure can be enhanced so that the rear independent suspension structure can be suitable for vehicles of different models, meanwhile, the machining difficulty is simplified, and the overall strength is improved; therefore, the running requirements of heavy vehicles under the conditions of heavy vehicle body weight and severe road conditions are met.
Description
technical field [0001] The invention belongs to the technical field of vehicle suspension systems, and in particular relates to a rear independent suspension structure for heavy vehicles. Background technique [0002] The suspension system is an important part of the vehicle. As a guiding mechanism for tire movement and a force transmission structure, it has a great impact on the ride comfort and handling stability of the vehicle; the control arm is a key component in the vehicle suspension. Its main function is to constrain the trajectory of the suspension system and transfer loads. [0003] In the prior art, the rear suspension mechanism of passenger car models mostly adopts the form of a rear multi-link suspension. The cost of design, production and logistics is relatively high, and it is not suitable for heavy vehicles. [0004] Most of the existing heavy-duty truck suspensions use leaf springs. Leaf springs belong to non-independent suspension structures, which are he...
