Problems solved by technology

[0004] Through the analysis of the suspension structure as described in the above patent, the disadvantages of the suspension structure are found: 1. The temperature in the engine compartment is high, the environment of the suspension structure is relatively harsh, and the rubber parts are easy to heat and harden, thus failing , leading to poor shock absorption effect, weak fixation of the powertrain, shaking, etc.; 2. Due to the installation of rubber buffers, the connection stiffness between the powertrain and the subframe 3. Setting a buffer of a single material will easily lead to resonance between the powertrain and the sub-frame assembly, thereby causing damage to the suspension structure or even failure; 4. Poor buffering effect will also cause The noise generated between the powertrain and the sub-frame assembly is relatively large, which affects the comfort of the vehicle

Embodiment 1

[0023] Such as figure 1 Shown, a kind of automobile powertrain suspension structure, automobile comprises powertrain and sub-frame assembly 1, suspension structure comprises the mounting support-21 that is fixedly connected with sub-frame assembly 1 and with power assembly The fixed mounting support two 22 is also provided with a helical damping spring 3 between the mounting support one 21 and the mounting support two 22, and the suspension structure also includes a fixed connection between the mounting support one 21 and the installation support The limiting member 4 between the second support 22 is placed in the helical through hole of the shock absorbing spring 3 and only allows the power assembly to move along the axial direction of the shock absorbing spring 3 . A plurality of above-mentioned suspension structures support the powertrain at multiple points, and a helical shock absorbing spring 3 is used to connect between the mounting support one 21 and the mounting suppor...

Embodiment 2

[0027] The content of this embodiment is roughly the same as that of Embodiment 1, the difference is that cavity 1 43 and cavity 2 44 are filled with hydraulic oil, and the principle of this solution is the same as that of the above solution. The first cavity 43 and the second cavity 44 are filled with hydraulic oil, which makes it easier to seal between the piston 45 and the barrel 42 .

Abstract

The invention provides an automobile power assembly suspension structure and belongs to the technical field of automobiles. The technical problem that an existing power assembly suspension structure can not consider the damping effect and the limiting effect of a power assembly is solved by the automobile power assembly suspension structure. According to the automobile power assembly suspension structure, an automobile comprises a power assembly and an auxiliary frame assembly; the suspension structure comprises a first installation support fixedly connected with the auxiliary frame assembly and a second installation support fixedly connected with the power assembly. A spiral damping spring is arranged between the first installation support and the second installation support. The suspension structure further comprises a limiting piece fixedly connected between the first installation support and the second installation support and arranged in a spiral through hole of the damping spring, so that the power assembly is only allowed to move in the axis direction of the damping spring. The automobile power assembly suspension structure has the advantages that the damping effect is good, the limiting effect between the power assembly and the auxiliary frame assembly is good, and service life is long.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile power assembly suspension structure. Background technique [0002] The suspension system of the automotive powertrain is an important component for multi-point support and limitation of the powertrain. In addition to the basic functions of support and limitation, the suspension system should isolate the powertrain, reduce noise, and eliminate Resonance and other effects to improve the NVH performance of the car. [0003] The suspension system connects the powertrain with the sub-frame assembly through multiple suspension structures. In the prior art, almost all automotive powertrain suspension systems are realized by using multiple anti-torsion tie rods. For example, the Chinese patent [CN202937721U] discloses a novel anti-twist tie rod, which aims to overcome the shortcomings of the anti-twist tie rod in the prior art, such as insufficient stability in longitudi...
