Abstract
The utility model discloses a kind of closing of trailer balance shaft to cover, including the first ring set and the second ring set；First ring set and the second ring set are all cylindrical structures, and the first ring set is fixedly connected on the top surface of the second ring set, and the first ring set and the second ring set are to be coaxially disposed；The center of first ring set is provided with through hole, and the center of the second ring set is provided with groove, and through hole is connected with groove；The front and rear sides of the groove be with the second ring set outer wall curvature identical circular arc, be the straight line being parallel to each other at left and right sides of groove；Spacing at left and right sides of the groove is more than the internal diameter of through hole；Junction on rear side of the groove with through hole is provided with limited block.The end of former balance sleeve is changed to enclosed construction by the utility model by open type, balance shaft is closely connected with axle sleeve, is effectively increased the mechanical performance and load-carrying properties of axle sleeve, is advantageous to increase the service life.
Description
Technical field
It the utility model is related to trailer accessories field, and in particular to a kind of trailer balance shaft closing set.
Background technology
Balance shaft is to form the important component of trailer hanging device, and it is each with balance to play transmission load by the leaf spring of series winding
Take turns the effect of between centers load.Needing that Upper shaft sleeve is installed in balance shaft, axle sleeve plays fixation, can prevent balance shaft from rotating,
Improve the stability of counter-jib.Existing axle sleeve is typically to be made of 20# seamless tubular goods, and end is open type, works as trailer
When bumpy road travels, the openend of axle sleeve is larger by stress, easily ruptures, and service life is shorter, so as to cause to put down
Weighing apparatus arm swing makes to produce relative rotation between balance shaft and axle sleeve, and potential safety hazard is brought to trailer traveling.
Utility model content
In order to overcome the technical deficiency of existing balance sleeve, the utility model provides a kind of trailer balance shaft closing set,
Current balance shaft sleeve end opening can be improved and be easily broken the problem of causing service life shorter.
Technical scheme is used by the utility model solves its technical problem：A kind of trailer balance shaft closing set, including
First ring set and the second ring set；First ring set and the second ring set are all cylindrical structures, and the first ring set is fixedly connected on the second ring
The bottom surface of set, the first ring set and the second ring set are to be coaxially disposed；The center of first ring set is provided with through hole, in the second ring set
The heart is provided with groove, and through hole is connected with groove；The front and rear sides of the groove are and the second ring set outer wall curvature identical circular arc
Shape, it is the straight line being parallel to each other at left and right sides of groove；Spacing at left and right sides of the groove is more than the internal diameter of through hole；It is described recessed
The front and rear sides of groove and the junction of through hole are provided with limited block.
Further, first ring set and the second ring set are by 25# steel one forging moldings.
Further, the limited block is and the second ring set outer wall curvature identical arc-shaped structure.
Further, first ring set and the top surface of the second ring set and bottom surface are all smooth flats.
The beneficial effects of the utility model are trailer balance shaft closing sets, to existing trailer balance shaft axle sleeve structure
Optimize, the end of former balance sleeve be changed to enclosed construction by open type, balance shaft is closely connected with axle sleeve,
The mechanical performance and load-carrying properties of axle sleeve are effectively increased, is advantageous to increase the service life.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is profile of the present utility model.
Fig. 2 is top view of the present utility model.
Indicated in figure, 1. first ring sets, 2. second ring sets, 3. through holes, 4. grooves, 5. limited blocks.
Embodiment
Reference picture 1-2, a kind of trailer balance shaft closing set, including the first ring set 1 and the second ring set 2；First ring set 1 and
Two ring sets 2 are all cylindrical structures, and the first ring set 1 is located at the bottom surface of the second ring set 2, and the first ring set 1 and the second ring set 2 are coaxial
Set；The center of first ring set 1 is provided with through hole 3, and the center of the second ring set 2 is provided with groove 4, and through hole 3 is connected with groove 4
Logical, balance shaft insertion through hole 3 in groove 4 with installing；The front and rear sides of the groove 4 are identical with the outer wall curvature of the second ring set 2
Circular arc, the left and right sides of groove 4 is the straight line being parallel to each other；The spacing of the left and right sides of groove 4 is more than the interior of through hole 3
Footpath, balance shaft is facilitated to insert；The front and rear sides of the groove 4 are provided with limited block 5 with the junction of through hole 3, and limited block 5 is to balance
Axle is further fixed.
As the presently preferred embodiments, the ring set 2 of the first ring set 1 and second is by 25# steel one forging moldings, is had good
Plasticity and intensity.
As the presently preferred embodiments, the limited block 5 is and the outer wall curvature identical arc-shaped structure of the second ring set 2.
As the presently preferred embodiments, the top surface of the ring set 2 of the first ring set 1 and second and bottom surface are all smooth flats, enter one
Step increase and the contact surface of balance shaft.
