Bolts are used to connecting the front axle, the connection sole, the 1/4 elliptic spring guiding arm and the 1/4 elliptic spring guiding arm in the top-down sequence. The utility model, enabling the automobile of well ride and stable operation, has the advantages of the low cost, simple structure, reasonable arrangement and coach demand saturation.
Description
(1) technical field
The utility model relates to a kind of automobile-used draft hitch.
(2) background technology
Automobile-used draft hitch is the general name that elastic joint part divides between automobile chassis frame and vehicle bridge, is used for supporting frame, transmits various power and moment between road surface and vehicle frame, alleviates and absorbs impact and vibrations when travelling.Existing automobile-used draft hitch mainly comprises elastic element and the guiding mechanism that is connected between vehicle frame and the propons, and elastic element commonly used mainly contains laminated spring, coil spring, rubber spring and air bellow.Air bellow all adopts diaphragm type air spring, and diaphragm type air spring is arranged in the vehicle bridge top, and what also have is placed on diaphragm type air spring above the steering swivel.The guiding mechanism of conventional air suspension is to form with two 1/4 oval steel springs, screening glass (bag auricle), be placed on main leaf (roll coil of strip auricle) below, intensity is lower, weight is bigger.Because there is weak point in the traditional suspension structure at aspects such as the coupling of the layout pattern of guiding mechanism, elastic element, gas spring patterns, make suspension frame structure complexity, productive costs height, the gentle spring base of guiding mechanism arrange that relatively difficulty, suspension property can not fully satisfy (comprising vehicle handling stability and ride comfort) operating needs of passenger vehicle.
(3) utility model content
The purpose of this utility model provides a kind of front axial double curve sac type single longitudenal arm air suspension frame structure, and the existing automobile-used draft hitch complex structure of solution, productive costs height, the gentle spring base of guiding mechanism are arranged the technical matters unreasonable, that suspension property can not fully satisfy the passenger vehicle operating needs.
The technical solution of the utility model: this front axial double curve sac type single longitudenal arm air suspension frame structure, mainly comprise the elastic element and the guiding mechanism that are connected between vehicle frame and the propons, it is characterized in that: above-mentioned elastic element is a double-convolution bellows type air spring, the upper end of double-convolution bellows type air spring connects to ground, and the lower end of double-convolution bellows type air spring places on the gas spring base of propons top; Above-mentioned guiding mechanism is the vertical unidirectional 1/4 oval steel spring guide arm of putting, the ear-rolling end of 1/4 oval steel spring guide arm is connected with the guide arm bearing that is fixed in vehicle frame, the postmedian of 1/4 oval steel spring guide arm is sandwiched in gas spring base and is connected between the base plate, in proper order propons, connection base plate, gas spring base are coupled together from bottom to top by bolt, connecting the base plate front end is connected with the rear end of stabilizer rod, the front end of stabilizer rod is connected with the lower end of boom support, and the upper end of boom support connects to ground.
The main leaf of above-mentioned 1/4 oval steel spring guide arm is the changeable section plate spring of an end roll coil of strip earhole; the thickness of main leaf is gradually approached by thick to grasswort hole direction along length; screening glass is the leaf spring such as sheet such as grade that an end encases main leaf grasswort hole, and screening glass is fixed in above the main leaf by fastening bolt.
The utility model is compared the beneficial effect that has with existing conventional art: the utility model has overcome the shortcoming of existing combined type air suspension, the double-convolution bellows type air spring cost is low, air bellow and gas spring base and guiding mechanism connection and reasonable arrangement, 1/4 oval steel spring only plays the guiding mechanism effect, do not bear vertical load, make vehicle under different loads height and the rigidity of suspension remain unchanged substantially, when vibration takes place and impacts in vehicle, can the reasonable distribution load-carrying, relax and impact, damped vibration increases the traveling comfort of taking, and it is in light weight, simple in structure, productive costs is low, makes automobile have good ride comfort and operation stabilization performance, can guarantee that guide arm has higher-strength, can fully satisfy the operating needs of passenger vehicle.
