The slewing bearing is used as a torsion point, the swing angle of the frame is greatly improved, the degree of freedom is larger, and the frame can move to a larger extent, so that the frame has smaller requirements on the turning radius of the track, and the running comfort is higher.

Description

Wheel train and frame connecting mechanism

Technical Field

The utility model relates to a special type vehicle design field specifically says to a train and frame connection mechanism.

Background

In the prior art, a traditional gear train is generally arranged at the bottom of a vehicle and runs along a rail, so that the traditional gear train is limited by large field environment and weak sight visiting effect. Therefore, the rail is arranged at a high position, and the wheel system is arranged below the rail, so that the visual field is wider, and the stimulation is higher.

For the latter scheme, in the prior art, a main shaft is adopted in a wheel train and frame connecting mechanism to penetrate through a joint bearing to realize directional torsion, and the mechanism is generally applied to swinging motion, tilting motion and rotating motion with low speed, the swinging angle of the mechanism is relatively small, and the stress structure is relatively weak.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects in the prior art and providing a wheel train and frame connecting mechanism, wherein the wheel train is positioned above the frame and is connected with the frame through a tailstock slewing bearing and a headstock slewing bearing; the tailstock slewing bearing comprises a hanging bracket, a slewing bearing, a flange part and a pin shaft, wherein the outer ring of the slewing bearing is connected with a wheel train through the hanging bracket, the inner ring of the slewing bearing is fixedly connected with the flange part, an ear plate is arranged at the connecting position of the frame and the tailstock slewing bearing, through holes matched with the pin shaft are arranged on the flange part and the ear plate, the axis of each through hole is parallel to the advancing and retreating directions of the frame, and the ear plate is rotatably connected with the flange part through the pin shaft; the locomotive head slewing bearing comprises a hanging bracket, a slewing bearing and a vehicle connecting rod, wherein the outer ring of the slewing bearing is connected with a wheel train through the hanging bracket, the inner ring of the slewing bearing is fixedly connected with the vehicle connecting rod, and the vehicle connecting rod is fixedly connected with a frame.

Preferably, the number of the tailstock slewing bearing and the number of the headstock slewing bearing are both 1.

Preferably, the number of the wheel trains is two, wherein each wheel train comprises a plurality of wheels.

Preferably, the end of the pin shaft is provided with a buckle or a bolt

Compared with the prior art, the utility model overcomes the defects of the traditional train of the prior art, such as small swing angle, low speed environment, low comfort level, poor stress structure and the like with the frame connecting mechanism. The slewing bearing is used as a torsion point, the swing angle of the frame is greatly improved, the degree of freedom is larger, and the frame can move to a larger extent, so that the frame has smaller requirements on the turning radius of the track, and the running comfort is higher.

Detailed Description

Embodiments of the present invention will now be described with reference to the accompanying drawings. As shown in figure 1, the connecting mechanism for the gear train and the frame comprises a tailstock slewing bearing (1), a headstock slewing bearing (2), a gear train (3) and a frame (4).

The wheel train (3) is positioned above the frame and is connected with the frame (4) through the tailstock slewing bearing (1) and the headstock slewing bearing (2).

As shown in fig. 2, the tailstock slewing bearing (1) comprises a hanger (1.1), a slewing bearing (1.2), a flange part (1.3) and a pin shaft (1.4).

The flange piece (1.3) is connected with the inner ring of the slewing bearing (1.2), and the outer ring of the slewing bearing (1.2) is connected with the gear train (3) through the hanging bracket (1.1).

The frame is provided with otic placode (1.5), be provided with on flange spare (1.3), otic placode (1.5) with round pin axle (1.4) complex through-hole, the axis of through-hole with the frame is advanced and is retreated the direction parallel, realizes that otic placode (1.5) and flange spare (1.3) rotatable is connected through round pin axle (1.4). The end part of the pin shaft (1.4) is provided with a buckle or a bolt to prevent the pin shaft (1.4) from falling off.

Due to the existence of the slewing bearing (1.2), the pin shaft (1.4) and the through hole, the wheel system (3) and the frame (4) obtain larger degree of freedom, more working strokes are achieved, and the comfort level is higher.

As shown in fig. 3, the headstock slewing bearing (2) comprises a slewing bearing (2.1) and a vehicle connecting rod (2.2), and the outer ring of the slewing bearing (2.1) is connected with the gear train (3) through a hanger like the tailstock slewing bearing (1). The frame (4) is connected to the inner ring of the slewing bearing (2.1) through a vehicle connecting rod (2.2) to form a rotating mechanism, and a degree of freedom is greater than that of the traditional technical scheme.

The connecting mechanism between a complete wheel train (3) and a frame (4) is formed by the tailstock slewing bearing (1) and the headstock slewing bearing (2), the headstock slewing bearing (2) bends firstly, a cross-shaped turning mechanism (slewing bearing, pin shaft and through hole) on the tailstock slewing bearing (1) structure bends in a matched mode, the bending, smaller bending rail requirements and running stability of the frame are achieved, and therefore the frame can run in a harsher place.

The gear train quantity is two sets of, is connected with rear of a vehicle slewing bearing (1), locomotive slewing bearing (2) respectively, as shown in fig. 3, can include a plurality of wheels in every group gear train (3), can improve equipment's security like this

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
