The engine front mounting main structure is to come vibration isolation and erosion control through two the V-shaped oblique installing type cushions in front.This structure major defect has:
Occurrence probability is higher when 1. occurring resonance phenomenon, especially motor easily and being in idling mode or high speed;
2. in actual the use, preceding suspending cushion damages easily, and rate of fault is higher, in case cushion damages, the car load vibration and noise will obviously increase the weight of, and travelling comfort seriously descends;
3. suspending cushion is after air-conditioning belt pulley and the tensioning simultaneously of water tank belt pulley; Because the stressed difference in both sides; A side that will suspend before will causing in the cushion of both sides presents compressive state, and the opposite side cushion then is in vacant state basically, and motor is by 4 supports of Design Theory; Become actual asymmetric supported at three point, thereby caused whole engine mounting damping property to descend.
4. owing to the supporting band inclined-plane, manufacturing is difficult to guarantee that assembly error is bigger with installation precision.
Summary of the invention
The object of the invention is exactly that a kind of simple in structure, easy to assembly, dimension precision requirement is low, damping property good, reliability is high motor shockproof structure is provided in order to overcome the defective that above-mentioned existing technology exists.
The object of the invention can be realized through following technological scheme: a kind of motor shockproof structure; This structure is arranged on the vehicle frame; It is characterized in that; Comprise preceding mounting bracket, engine front mounting cushion, motor front-bank rotor housing support; Mounting bracket is provided with the engine front mounting cushion through being bolted on the vehicle frame between described preceding mounting bracket and the motor front-bank rotor housing support before described, and described engine front mounting cushion and motor front-bank rotor housing support are through on the mounting bracket before being bolted to; Described motor front-bank rotor housing support comprises motor front-bank rotor housing left socle and motor front-bank rotor housing right support, and described motor front-bank rotor housing left socle and motor front-bank rotor housing right support are the mirror image symmetry about the surface plate at the central shaft place of vehicle frame.
Mounting bracket is provided with two mutually perpendicular surface plates before described; I.e. first surface plate and second surface plate; Described first surface plate is through being bolted on the vehicle frame, and described second surface plate is fixed together through bolt and engine front mounting cushion, motor front-bank rotor housing support.
