Abstract
The utility model relates to a cast thrust rod for a motor truck, which relates to a thrust rod used for automobiles. The utility model comprises a pin shaft, a rod seat and a rod body, wherein the pin shaft in an inner cavity of the rod seat and metal end covers of both ends are cured into a whole through rubber bodies; the rod body is divided into two segments connected with each other through an adjusting connecting rod. The pin shaft is provided with a groove for processing, and the pin shaft presents a spindle shape. One side of the inner cavity of the rod seat is provided with a rabbet, and the other side is provided with a clamp spring groove. A contact surface of a pin shaft assembly and the rod seat of the utility model is a rubber outer circumference surface; compared with the traditional thrust rod, the stress condition is improved and the service life is extended. Because the relative movement of the rod seat and the pin shaft can be realized by deformation of the rubber body, the pin shaft assembly needs no lubrication and service and maintenance cost can be saved. The pin shaft is designed to a spindle shape to improve the bearing capacity of the pin shaft. The length of the thrust rod can be adjusted through a rotary adjusting connecting rod so as to adjust the state of the vehicle bridge conveniently. The utility model has the advantages of convenient installation, reliable performance, etc.
Description
Technical field
The utility model relates to the propelling rod that a kind of automobile is used, particularly a kind of propelling rod that is applicable to that heavy motor vehicle duplex bridge is used.
Background technology
On the heavy motor vehicle of assembling balance suspension, air suspension and rubber suspension propelling rod is housed all at present.Traditional propelling rod generally is made up of shaft and bar head two parts, its king-rod head is a key component, be made up of parts such as pole socket, bearing pin, ball seat, ball seat lining, clamping ring, gland, jump ring, guard shield and end caps as traditional bar is first, amount of parts is many, complex structure; In use, necessary intermittent oiling and maintenance are in the reality driving, owing to road conditions, overload and lubricated reason such as untimely, wherein ball seat lining and ball seat damage especially easily, after above-mentioned two inefficacies, the stressed deterioration of bearing pin and pole socket, take place the two one of fracture cause propelling rod to lose efficacy.Because bearing pin design and process unreasonablely fracture accident takes place in the actual driving easily causes the propelling rod back axle positioning skew of losing efficacy, cause transmission shaft to damage again in addition, the generation that has big train operation accident.Traditional in addition propelling rod length is fixed, and can easily not adjust the motoring condition of vehicle bridge by the length of adjusting propelling rod.
Summary of the invention:
The utility model is at the deficiencies in the prior art, and the goods carrying vehicle cast-type propelling rod of a kind of rational in infrastructure, easy to assembly, dependable performance and shaft adjustable in length is provided.
The utility model is achieved through the following technical solutions: comprise bearing pin, pole socket and shaft, wherein, the bearing pin of pole socket inner chamber and the metal end at two ends are one by rubber bodies curing, shaft is divided into two sections, connects by adjusting extension bar between it.
The groove that processing is arranged on the bearing pin.
Bearing pin is spindle.
Pole socket inner chamber one side has seam, opposite side jump ring groove.
The utility model has promptly replaced the ball seat and the ball seat lining of original rapid wear by changing the pole socket inner structure with rubber bodies, make bonding being integral of rubber bodies and metal piece sulfuration; In order to make rubber bodies and bearing pin bonding more firm, on bearing pin, be provided with the groove of processing; To cut the stressed of axle in order improving,, to have improved working accuracy, avoid processing the stress concentration that tool marks are brought cutting a spindle that is processed into equal stress beam form; With separated in the shaft, process screw thread, load onto a screwed adjustment extension bar in two ends, clamping stirrup is equipped with in the threaded connection place.At work, the bearing pin assembly and the pole socket of propelling rod do relative motion.The utility model is the outer circumference surface of rubber bodies by the contact surface with bearing pin assembly and ball seat, the more traditional propelling rod of stressing conditions is improved greatly, improved service life: owing to rely on the distortion of rubber bodies to realize relative motion with pole socket, so the bearing pin assembly need not lubricate, can save maintenance, maintenance cost greatly.According to the actual loading and the Mechanics Calculation of bearing pin, be spindle with the bearing pin optimal design, the pin bearing loading capability is improved.Adjust extension bar by rotation and can adjust the length of propelling rod, thereby can adjust the state of vehicle bridge easily.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, bearing pin, 2, metal end, 3, jump ring, 4, rubber bodies, 5, pole socket, 6, shaft, 7, clamping stirrup, 8, adjust extension bar, 9, binding bolt.
The specific embodiment
Embodiment: structure becomes an integral body with metal end 2 usefulness rubber bodies 4 sulfuration at bearing pin 1 and two ends is bonding as shown in drawings, is called the bearing pin assembly.Pole socket 5 inner chambers one side is processed into seam, and opposite side is processed with the jump ring groove, then the bearing pin assembly is pressed in pole socket 5 chambeies, is pressed into jump ring 3 after putting in place, is called the pole socket assembly.One end endoporus of shaft 6 is processed with screw thread, the other end and the hot pressing of pole socket assembly are one, the clamping stirrup 7 that will have binding bolt 9 is inserted in the threaded end of shaft 6 processing, with adjusting extension bar 8 two above-mentioned shafts 6 is connected to a complete propelling rod at last.
