Problems solved by technology

[0002] At present, the chassis suspension system of commercial vehicles mostly uses leaf springs for vibration reduction. Due to the high natural frequency of the leaf springs, when the vehicle is driving on an overturned road, the vibration reduction effect is poor and the service life is short. On the other hand, the weight of the leaf springs cannot meet the requirements of current vehicles. The trend of technology lightweight and comfortable development

Embodiment Construction

[0009] Such as figure 1 As shown, the bottom end of the capsule 5 is press-fitted with the side wall of the piston 6, the upper end of the capsule 5 is buckled and connected with the upper cover plate 3, and one end of the upper cover plate 3 is respectively provided with a trachea joint 1 and a positioning pin 2, and the trachea The joint 1 is hollow and communicates with the inside of the capsule 5. There is a protrusion in the middle of the bottom end of the upper cover plate 3. The emergency stopper 4 is connected with this protrusion. The entire piston 6 is made of metal material and is integrally constructed. The bottom end is also provided with a bolt hole. The gas pipe joint 1 is mainly used to connect the gas pipeline; the main function of the positioning pin 2 is to install and position, and the upper cover plate 3 is used to seal the gas and install; the main function of the emergency stop 4 is to carry out emergency stop in case of accident; the capsule 5 is an el...

Abstract

The invention discloses a chassis air spring, which is characterized in that the bottom end of a capsule is press-mounted with the side wall of a piston, the upper end of the capsule is buckled and connected with an upper cover plate, a gas pipe joint and a locating stud are respectively arranged at one end of the upper cover plate, the gas pipe joint is hollow and communicated with the interior of the capsule, a bulge is arranged in the middle of the bottom end of the upper cover plate, an emergency stopping block is connected with the bulge, the whole piston is made of metal materials and has an integrated structure, and a bolt hole is arranged at the bottom end of the piston. By the above setting, the chassis air spring is lighter than the original steel spring plate and improves the damping effect simultaneously, thus meeting the requirements of the current vehicle technology for light weight and comfort and satisfying the requirements of vehicles for driving on roads with various complicated conditions.

Description

technical field [0001] The invention relates to a novel commercial vehicle shock absorber element, specifically an air spring assembly applied to vehicle chassis suspension. Background technique [0002] At present, the chassis suspension system of commercial vehicles mostly uses leaf springs for vibration reduction. Due to the high natural frequency of the leaf springs, when the vehicle is driving on an overturned road, the vibration reduction effect is poor and the service life is short. On the other hand, the weight of the leaf springs cannot meet the requirements of current vehicles. The trend of technology lightweight and comfortable development. Contents of the invention [0003] In order to improve the disadvantages of the current leaf springs, such as high natural frequency, poor vibration damping effect, short service life and heavy weight, the present invention improves its structure and material on the premise of satisfying the original performance. [0004] Th...
