Description
Technical Field
The utility model belongs to the technical field of special motor vehicle suspension systems, and particularly relates to a rocker arm type suspension device with a novel structure.
Background
The current road sweeper develops towards high flexibility and diversified functions, the structure of the current road sweeper is gradually complicated, and therefore the space of a chassis is small, and a suspension system is difficult to install. Most road sweeper sacrifice the travelling comfort to function diversification, high compromise of flexibility to because of the whole car does not have suspension system to lead to the road sweeper travelling comfort poor, drawback such as navigating mate occupational disease risk increase. The suspension system of the traditional load-carrying vehicle, namely the suspension system of the plate spring matched with the damper, is installed on part of the road sweeper, and has the defects of large occupied space, limited damping effect caused by large rigidity of the plate spring for carrying and the like. There is a need for a new suspension system that occupies a small space, has a high load-bearing capacity, and is comfortable.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a rocker arm type suspension device which has strong bearing capacity, compact structure and high reliability, lightens impact load and reduces and eliminates chassis resonance amplitude.
The rocker arm type suspension device is characterized by comprising a rocker arm and an hourglass-shaped rubber shock absorption block, wherein the rocker arm is U-shaped, one end of the U-shaped rocker arm is provided with a mounting hole, the mounting hole is used for connecting one end of the U-shaped rocker arm with a vehicle frame through a pin shaft, and the other end of the U-shaped rocker arm is connected with the vehicle frame through the hourglass-shaped rubber shock absorption block.
In order to further achieve the purpose of the utility model, the bottom surface of the U-shaped rocker arm is an axle mounting surface, a composite bearing is arranged in a front end mounting hole, and a mounting seat for mounting an hourglass-shaped rubber shock absorption block is arranged at the rear end.
In order to further achieve the purpose of the utility model, the hourglass-shaped rubber shock absorption block can be formed by integrating two conical ends of two conical rubber shock absorption blocks.
Compared with the prior art, the utility model has the following remarkable characteristics and positive effects: the U-shaped rocker arm is manufactured by welding or casting, the bottom surface of the U-shaped rocker arm is processed into an axle mounting surface, the composite bearing is mounted in the front end mounting hole, the rear end of the U-shaped rocker arm is welded with the hourglass-shaped rubber shock-absorbing block mounting seat, the axle and the U-shaped rocker arm are fixedly connected by using bolts without using riding bolts and pressing plates, and the U-shaped rocker arm is high in bearing capacity, compact in structure and high in reliability; the front end of the U-shaped rocker arm is inserted into the mounting hole through a pin shaft and is connected with the frame, so that the axle can freely move up and down along with the fluctuation of the road surface and can bear the impact load from the road surface; the bottom of the hourglass-shaped rubber shock absorption block is arranged between the U-shaped rocker arm and the frame, the hourglass-shaped structure which is designed by matching the characteristics of the rubber shock absorption block, such as good elasticity, wear resistance, tear resistance, compressibility and the like, is used for bearing rear axle load and replacing a damper to reduce and eliminate chassis resonance amplitude, the diameter of the middle of the hourglass-shaped structure is small, the hourglass-shaped structure is easy to rebound, and the diameters of two ends of the hourglass-shaped structure are gradually increased, so that the shock absorption block is good in elasticity and high in comfort when in no-load, and can be compressed along with the increase of load, and the bearing capacity of the shock absorption block is gradually increased.
