Structural form of engine suspension mount

In the design of engine mount, the purpose of mount, such as the quality of support and limited displacement, must be fully considered, and the reasonable shape must be chosen. There are three basic types of mounting: compression, shearing and tilting (see figure below).(Thanks for the help and support of Chongqing Feilong Jiangli Auto Parts technical department)

If the displacement of the power assembly is too large, the total power cost will be caused, or the intake and exhaust system, control mechanism, pipeline, wiring and other peripheral parts will be damaged. At the same time, the mounting cushion is easy to damage. For this reason, suspension stiffness must be limited from overhanging structure 1, plus larger displacement. For example, when a car is accelerating or turning, the inertia force generated by the power assembly may cause a greater displacement of the power assembly. In order to limit the displacement of power assembly, it is necessary to design rigid suspension, that is, large stiffness suspension cushion 2, nonlinear and variable stiffness suspension structure, in order to reduce the vibration caused by small exciting force and limit the large vibration displacement when large exciting force. For example, the engine output torque is small when the car stops idling, or when the car runs at a constant speed. At this time, the lower stiffness of the suspended cushion should be designed to effectively isolate vibration. But in the fast start, the reaction force of the driving torque is very large, which can make the power assembly produce greater vibration. In addition, when the vehicle is running on uneven road surface, with the large ups and downs of the whole vehicle, the dynamic assembly also produces great up and down inertia. At this time, the stiffness of the suspension cushion is increased, which can effectively limit the vibration and position of the power assembly. Shift

    • OEM vs. Aftermarket Parts for Your Car: How to Choose
      When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.

      Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.

      You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.

      Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.

    • Replacement Intervals For Oil And Air Filters In Today’s Vehicles
      The factory-recommended replacement intervals for filters can vary quite a bit depending on the year, make and model of the vehicle, as well as how it is driven. As a rule, older vehicles (those more than 15 to 20 years old) typically have more frequent service intervals than newer vehicles. Why? Because late-model vehicles require less maintenance, thanks to improvements in motor oils, transmission fluids, engine design and filter media.

      Many long-life air and oil filters use synthetic fiber media or a blend of cellulose and synthetic fibers to extend filter life.

      Changing the oil and filter every 3,000 miles was standard practice decades ago. But it’s no longer necessary because most multi-viscosity oils today are a synthetic blend or a full synthetic that resist viscosity breakdown and oxidation for a much longer period of time. Late-model fuel-injected engines also run much cleaner than their carbureted ancestors, which reduces oil contamination in the crankcase.

      Hello, someone crashed through my fence, ran and left a piece of his truck. Just trying to figure out what exactly the part is, and if it goes to a certain model.

      The number of mounting points depends on the length, mass, use and installation of the power assembly. The mounting system can be mounted at 3, 4 and 5 points. Generally, three-point and four-point mounting systems are used in automobiles, because if the number of mounting points increases when the vibration is relatively large, when the body deformation, some mounting points will be dislocated, so that the engine or mounting bracket force is too large and cause damage to the three points, the advantages of the support is that no matter how bumpy and jumping the car, it can always ensure the support. The point is in a plane, which greatly improves the force condition of the body. The front and rear suspensions of the four-point mount are mainly used to prevent the torsion of the power assembly, and the torsional stiffness is larger than that of the three-point mount.
      Three point mounting system
      Left suspension: connect with gearbox, mainly power assembly limit and supporting function.
      The right suspension: connected with the engine, it can isolate the engine, such as vibration, inertia force and vibration.
      Rear suspension: It is connected with the gearbox, and has the functions of longitudinal limit, bearing torque, driving condition limit and so on.
      Four point mounting system
      It can overcome the large torsional reaction force, but the torsion stiffness is large, which is not conducive to the isolation of low frequency vibration.
      Left and right suspension: close to the torsional inertia axis, support the powertrain up and down, and have the function of vibration decoupling.
      Front and rear suspension: with the transmission, it has longitudinal limit, driving condition limit and torque endurance.

      Rubber bushing is mainly used in the position of automobile front and rear suspension and other frequent vibration. It plays a vital role in the whole vehicle NVH (Noise Vibration Harshness), and it will be invalid and will affect the whole vehicle noise and driving stability. The failure mode of rubber bushing is not only its own quality control, but also its working environment is one of the key factors affecting its life. Thanks for the support of the Feilong Jiangli technical department.
      Automobile suspension is a component that connects the frame (or body) with the axle (or direct and wheel). Its main functions are: D mitigates and inhibits vibration or shock caused by uneven pavement to ensure the car has good smoothness; 2 (2) rapidly attenuates the vibration of the body and axle (or wheel); 3 (3) transfer function in the wheel and frame (car) Various forces (vertical force, longitudinal force, transverse force) and moments (braking moment and reaction moment) between the body; 4) to ensure the necessary stability of the vehicle.
