Abstract
The utility model provides a combination spring of a road roller. Shock-absorbing springs of the road roller are installed between a roller shaft and a girder of the road roller. The combination spring of the road roller is characterized in that the roller shaft of the road roller is provided with two circles of concentric circular convex walls upwards, the position of the girder of the road roller corresponding to the two circles of convex walls is provided with two circles of concentric circular convex walls downwards, the combination spring of the road roller is provided with two coaxial shock-absorbing springs of the road roller, one of the shock-absorbing springs of the road roller is sleeved outside a convex wall with a large diameter, and the other shock-absorbing spring of the road roller is sleeved outside a convex wall with a small diameter. The combination spring of the road roller has the advantages that the vertical concentric circular convex walls are utilized to enable the spring with the small diameter to be sleeved in the spring with the large diameter so as to achieve stable fixing and the mutual interference is avoided. By the arrangement of the two coaxial springs, on one hand, the service life of the springs is prolonged, and on the other hand, when the springs perform actuation, the springs can meet the requirements for actuation strength without a large stroke.
Description
Affiliated technical field
The utility model relates to spring structure, relates in particular to employed spring on the road roller.
Background technology
Forcing press is the pavement construction machinery that generally uses, and it uses heavy weight roller drum, and the road surface of laying pitch or other road surface cladding materials is rolled so that the road surface is driven plain.
Between the roller shaft of road roller and road roller girder, the road roller damping spring is installed, its effect is to alleviate the influence of the vibrations of the roller of road roller to complete machine.But, the working environment of roller drum and abominable, the road surface is rugged, and it is very big to rise and fall, and fluctuations is violent, and often has lump protruding, so the compression frequency of this spring is very big, suppressed range is also unstable.Therefore the rupture failure that causes the road roller damping spring easily.
The utility model content
The utility model provides a kind of road roller combination spring, and its purpose is, overcomes the prior art shortcoming, improves the application life of road roller damping spring.
For realizing the foregoing invention purpose, the technical scheme that the utility model adopted is:
Road roller combination spring; Between the roller shaft of road roller and road roller girder, the road roller damping spring is installed; It is characterized in that: the roller shaft of road roller upwards is provided with the protruding wall of two circle concentric circles, to having the concentric boss wall of two circles, has two coaxial road roller damping springs on the road roller girder position corresponding with the protruding wall of above-mentioned two circles position; A road roller damping spring is set in outside the large diameter protruding wall, and another road roller damping spring is set in outside the protruding wall of minor diameter.
The beneficial effect of the utility model is: obtain stable fixing and can not interfere each other after utilizing concentric boss wall up and down to make the spring housing of minor diameter be located in the large diameter spring; The setting of two coaxial springs makes really being born by two springs of roller drum; Increased on the one hand the application life of spring, spring also need not bigger stroke and just can satisfy the demand of making amount of power when start on the other hand.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1; Roller shaft 1 at road roller upwards is provided with the protruding wall 11,12 of two circle concentric circles; Enclose concentric boss wall 21,22 to having two on road roller girder 2 positions corresponding with the protruding wall of above-mentioned two circles 11,12 positions; The also promptly top concentric boss wall 11,12 of two circles faces the following concentric boss wall 21,22 of two circles; Have two coaxial road roller damping springs 31,32; A road roller damping spring 31 is set in outside the large diameter protruding wall 11,21, and another road roller damping spring 32 is set in outside the protruding wall 12,22 of minor diameter, and with one heart the distance between boss wall 11 and the concentric boss wall 12 and concentric boss wall 21 and the distance between the concentric boss wall 22 equal the diameter of road roller damping spring 32; The top and bottom that also are road roller damping spring 32 be embedded respectively between concentric boss wall 11 and concentric boss wall 12 and concentric boss wall 21 and concentric boss wall 22 between, this spline structure is more firm.
Above-mentioned is one group of road roller combination spring, at the roller shaft and the road roller girder of road roller the such road roller of many groups can be set and make up springs.
Claims (1)
1. road roller makes up spring; Between the roller shaft of road roller and road roller girder, the road roller damping spring is installed; It is characterized in that: the roller shaft of road roller upwards is provided with the protruding wall of two circle concentric circles, to having the concentric boss wall of two circles, has two coaxial road roller damping springs on the road roller girder position corresponding with the protruding wall of above-mentioned two circles position; A road roller damping spring is set in outside the large diameter protruding wall, and another road roller damping spring is set in outside the protruding wall of minor diameter.
