Detailed Description

To make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but is merely representative of selected embodiments of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

Example 1

As shown in fig. 1-3, the front axle is taken as an example for description in this embodiment, and the product structure in this embodiment mainly includes a chassis 1, a wedge 2, a wedge guide plate 3, a wedge link 4, a wedge chute 5, and a hanging wheel lever 6. Wherein, two side surfaces of the chassis 1 are provided with a wedge sliding groove 5 which is higher than the highest height of the wedge 2 and has the depth about half of the width of the wedge 2, and then the wedge is embedded in the wedge sliding groove 5, so that the wedge 2 can slide in the wedge sliding groove 5 in a reciprocating way and can not shift. Then, a wedge 2 is arranged at the front wheel 7 and the rear wheel 7 which are on the same side, and the front wedge and the rear wedge are connected into a whole by a wedge connecting rod 4, so that the integral sliding can be realized. Then a hand jack 10 is arranged in the middle of the chassis 1, and a wedge connecting rod 4 is connected to the top of the hand jack 10, so that the reciprocating motion of the wedge is realized by controlling the jack. At the moment, a wedge guide plate 3 and a wedge guide plate slide rail 12 are arranged on the side surface of the chassis 1, the wedge guide plate 3 is matched with a wedge, and the wedge guide plate 3 can slide up and down along the wedge guide plate slide rail 12 in the height direction of the vehicle. The lifting wheel rod 6 is arranged on the wedge guide plate 3, the lower end of the lifting wheel rod 6 is connected with the axle 8, and the height of the wedge guide plate is changed through the wedge so as to drive the lifting wheel rod 6 to move upwards, so that the axle is lifted, and the purpose of single-axle and double-axle conversion is achieved. The damping effect of the damper 9 is changed correspondingly while the single-double bridge is changed. The shock absorbers 9 in this embodiment are used in such a manner that two shock absorbers are combined, and when the double axle is changed to the single axle, the shock absorbers 9 are also changed to one shock absorber, so that the shock absorbing effect is also changed accordingly.

Example 2

As shown in fig. 3-6, this embodiment is described with a rear bridge as an example: the product structure in this embodiment mainly includes a chassis 1, a wedge 2, a wedge guide plate 3, a wedge link 4, a wedge chute 5 and a hanging wheel lever 6. Wherein, two side surfaces of the chassis 1 are provided with a wedge sliding groove 5 which is higher than the highest height of the wedge 2 and has the depth about half of the width of the wedge 2, and then the wedge is embedded in the wedge sliding groove 5, so that the wedge 2 can slide in the wedge sliding groove 5 in a reciprocating way and can not shift. Then, a wedge 2 is arranged at the front wheel 7 and the rear wheel 7 which are on the same side, and the front wedge and the rear wedge are connected into a whole by a wedge connecting rod 4, so that the integral sliding can be realized. Then a hydraulic press 11 is arranged in the middle of the chassis 1, and a wedge connecting rod 4 is connected with a mandril of the hydraulic press 11, so that the wedge can reciprocate under the control of the hydraulic press 11. At the moment, a wedge guide plate 3 and a wedge guide plate slide rail 12 are arranged on the side surface of the chassis 1, the wedge guide plate 3 is matched with a wedge, and the wedge guide plate 3 can slide up and down along the wedge guide plate slide rail 12 in the height direction of the vehicle. The lifting wheel rod 6 is arranged on the wedge guide plate 3, the lower end of the lifting wheel rod 6 is connected with the axle 8, and the height of the wedge guide plate is changed through the wedge so as to drive the lifting wheel rod 6 to move upwards, so that the axle is lifted, and the purpose of single-axle and double-axle conversion is achieved. The number of the shock absorbers 9 in the embodiment is one, so that the effect of the shock absorbers is relatively small when the single-double bridge is switched. This embodiment is through changing the adjusting device of wedge into the hydraulic press by hand jack, and is more laborsaving when whole equipment uses like this.

The utility model discloses the theory of operation: the wedge is adjusted according to the load of a vehicle and the road condition when the vehicle runs, so that the vehicle can be converted on a single-double axle structure or converted between a long shaft and a short shaft, and particularly the adjustment of a main tire and a spare tire of the vehicle is realized by pulling the wedge by using the wedge adjusting device. When the wedge is adjusted to one end, the wheel at one end is lifted off the ground under the drive of the wedge guide plate to form a single-axle vehicle, and meanwhile, the shock absorber is also half softened. The wheel at the end away from the ground becomes a spare tire, which is similar to a two-wheel vehicle or a single-wheel vehicle, thereby improving the passing performance, the operation flexibility and the like of the vehicle. If the vehicle normally runs, the tire bursts suddenly, and after the vehicle stops, the wedge can be adjusted, so that the wheel at one end of the burst tire is separated from the ground upwards, and the vehicle runs as a single-axle vehicle, and the running safety of the vehicle is improved. Generally, the vehicle is in an unadjusted state, and the front wheels and the rear wheels of the vehicle are all grounded, so that the vehicle is a double-axle vehicle and can stably run at a high speed.

When the load exceeds the specified load or the vehicle runs on a concave-convex road surface or is braked at high speed, the wheels at one end separated from the ground contact the ground when the vehicle body inclines forwards and sinks, so that the ground contact brake is formed, the running safety of the vehicle is improved, and when the wheels at one end separated from the ground contact the ground all the time, the vehicle returns to a double-axle vehicle.
