Detailed description of the invention
Core of the present utility model is to provide a kind of front overhang cylinder of dumping car, and this front overhang cylinder not only course of processing is simple, and can be connected with front wheel spindle failure-free.Another core of the present utility model is to provide a kind of dumping car with above-mentioned front overhang cylinder.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of detailed description of the invention of front overhang cylinder provided by the utility model.
In a kind of concrete embodiment, the utility model provides a kind of front overhang cylinder of dumping car, comprise cylinder body 1 and piston rod 2, described cylinder body 1 is sleeved on described piston rod 2, described cylinder body 1 is divided internally into rod chamber and rodless cavity by the piston of described piston rod 2, the end that described piston rod 2 is positioned at outside described cylinder body 1 has location structure 3, the described end of described piston rod 2 coordinates with front wheel spindle, described location structure 3 locates described front wheel spindle, so that described piston rod 2 is fixedly connected with described front wheel spindle.
The keystone configuration that Mai Fuxun hangs comprises coil spring and bumper, bumper offsets forward, backward, left, to the right when coil spring can be avoided stressed, restraining spring can only do the vibration of above-below direction, and can set soft or hard and the performance of suspension by the stroke length of bumper and degree of tightness.
The structural volume that Mai Fuxun hangs is less, adopts the vehicle that Mai Fuxun hangs, and actv. expands takes space in car, and the comfort level of chaufeur is better.Mai Fuxun hangs and requires that the piston rod 2 of front overhang cylinder is connected with front wheel spindle, and the junction of the two needs to bear certain steering torque.
When front wheel spindle is subject to the load from ground, by dynamic changes process to the piston rod 2 of front overhang cylinder, the load that piston rod 2 is subject to acts on the hydraulic oil of rodless cavity, can play certain buffer action to load; The other end of front overhang cylinder is connected with vehicle frame, and the load after front overhang cylinder buffering is delivered to vehicle frame.
Adopt the front overhang cylinder of said structure; in the end of piston rod 2, location structure 3 is set; when piston rod 2 is connected with front wheel spindle; located by location structure 3, guarantee piston rod 2 and the position relationship of front wheel spindle, be then fixedly connected with the two; the two is made to become to be integrated; when the junction of the two is subject to larger steering torque, can not rotate, the reliability of connection is higher.
Compared with prior art, this front overhang cylinder adds man-hour, can process separately, reduce difficulty of processing, can also be connected with front wheel spindle failure-free, improves the stability of car load and the comfort level of navigating mate.
Concrete, location structure 3 is positioning step, and front wheel spindle has the connecting through hole coordinated with the end of piston rod 2, and the orifice edge of connecting through hole supports the end face of positioning step.
Front wheel spindle has the contiguous block be connected with piston rod 2, contiguous block offers connecting through hole, so that the piston rod 2 of front overhang cylinder runs through, and supports the end face of positioning step by the orifice edge of connecting through hole, positioning step defines the movement of front wheel spindle at piston rod 2 axial direction.Piston rod 2 inserts this connecting through hole, is fixedly connected with piston rod 2 and front wheel spindle by the fixation kit of the orifice edge being arranged at connecting through hole.
Certainly, location structure 3 is not only confined to positioning step, can be also positioning boss, or be arranged on the steady ring that piston rod 2 is fixedly connected with radius stay 2.
Setting like this, improves the convenience that this front wheel spindle is connected with front overhang cylinder, and effectively simplifies the technique of front wheel spindle processing, avoids piston rod Mismachining tolerance and the connection unstability that causes; Meanwhile, improve the Joint strenght of front wheel spindle, ensure that failure-free service life.
One preferred embodiment in, the end face of positioning step has tapped bore, and piston rod 2 is connected by bolt with front wheel spindle.
The orifice edge of the connecting through hole of the contiguous block of front wheel spindle distributes multiple through hole, after piston rod 2 inserts connecting through hole, the end face of positioning step supports the orifice edge of connecting through hole, each tapped bore respectively with each through hole to corresponding, then by bolt, the two is fixedly connected with, realizes being fixedly connected with of piston rod 2 and front wheel spindle.
Further, the end face of positioning step is uniformly distributed multiple tapped bore.
The end face of positioning step can arrange the tapped bore of a greater number, is connected with the reliable of front wheel spindle for realizing piston rod 2.
Concrete, the quantity of tapped bore can set according to the size of front wheel spindle and piston rod 2, or according to load setting that the two bears.
In another preferred embodiment, positioning step has chamfering, and piston rod 2 welds with front wheel spindle.
After piston rod 2 inserts connecting through hole, the end face of positioning step supports the orifice edge of connecting through hole, and the chamfering place at the edge of positioning step forms one gap, as weld seam, can be fixedly connected with by piston rod 2 by the mode of welding with front wheel spindle.
In the respective embodiments described above, as shown in Figure 1, cylinder body 1 has the pin jointed end 4 be connected with vehicle frame.
The end of piston rod 2 is positioned at one end of cylinder body 1, and pin jointed end 4 is positioned at the other end of cylinder body 1, and cylinder body 1 is connected with vehicle frame, by dynamic changes process to vehicle frame by pin jointed end 4.
Except above-mentioned front overhang cylinder, the invention also discloses a kind of dumping car, the front wheel spindle comprise front overhang cylinder, being connected with front overhang cylinder, described front overhang cylinder is the front overhang cylinder described in above-mentioned any embodiment.
Because front overhang cylinder has above-mentioned technique effect, therefore the dumping car with this front overhang cylinder also has corresponding technique effect, and other structures of this dumping car please refer to prior art, repeat no more herein.
Above dumping car provided by the utility model and front overhang cylinder thereof are described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
