Description

Novel suspension cushion for fuel tricycle Technical Field The utility model relates to the field of vehicle engineering, in particular to a novel suspension cushion for a fuel tricycle. Background The fuel tricycle has become one of the main vehicles in rural and urban and rural joints, and the fuel tricycle mainly adopts a single-cylinder engine as a power source, and the engine and a vehicle body are connected through a suspension cushion. Due to the inherent vibration characteristics of a single-cylinder engine, a vehicle can transmit larger vibration to a vehicle body during running, and with the improvement of the requirements of the market on driving riding comfort, research on reducing the vibration of the vehicle body becomes more and more important. Vibration generated by engine operation can be divided into low-frequency vibration and high-frequency vibration, wherein the amplitude of the low-frequency vibration is larger, the amplitude of the high-frequency vibration is smaller, the design requirement on an engine suspension cushion is higher and higher, the suspension cushion is required to have higher dynamic stiffness and damping coefficient in the low-frequency vibration area of the engine so as to quickly reduce large amplitude, and the suspension cushion is required to have lower dynamic stiffness and damping coefficient in the high-frequency vibration area of the engine so as to absorb vibration more effectively and reduce conductivity. The related technology of a two-stage engine suspension device (publication number CN 2220005281U) for a fuel tricycle disclosed in the prior art can effectively reduce engine vibration and improve driving comfort, but the following problems still exist in the actual use process and need to be solved, but the following problems still exist: The engine suspension device has the advantages of complex design structure, high processing precision requirement and higher manufacturing cost, so that the engine suspension device has the advantages of simple structure, low processing precision requirement and lower manufacturing cost. The installation procedures are more, the requirement of the final assembly process is high, and the maintenance difficulty is high, so that the engine suspension device convenient to maintain and install is urgently needed. Disclosure of utility model The utility model mainly aims to provide a novel suspension cushion for a fuel tricycle, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: A novel suspension cushion for a fuel tricycle comprises an engine bracket, an upper cushion, a lower cushion, a vehicle body bracket and through holes, wherein the upper cushion is arranged at the lower end of the engine bracket, the lower cushion is arranged at the lower end of the upper cushion, the vehicle body bracket is arranged at the lower end of the lower cushion, and hexagon head bolts sequentially penetrate through the through holes of the engine bracket, the upper cushion, the lower cushion and the vehicle body bracket for connection and fixation; The upper soft cushion consists of an upper soft cushion flat cushion and an upper soft cushion rubber body, wherein the upper soft cushion flat cushion is arranged at the upper part of the upper soft cushion, an annular groove is arranged in the middle of the upper soft cushion rubber body, and a circular boss is arranged at the lower part of the upper soft cushion rubber body; The lower soft cushion consists of a lower soft cushion rubber body and a lower soft cushion flat cushion, wherein a circular groove is formed in the upper part of the lower soft cushion rubber body; The circular boss of the upper soft cushion is exactly matched with the circular groove of the lower soft cushion, so that positioning and guiding are realized, and low-frequency vibration and high-frequency vibration generated by an engine are absorbed together. Preferably, the through holes of the engine bracket, the upper cushion, the lower cushion and the vehicle body bracket are arranged at the center position. Preferably, the upper cushion flat pad and the lower cushion flat pad are made of Q235.
