Description

Technical Field

[0001] The present application relates to the field of rail transit equipment, and in particular to a stop-type steering shaft connection device, a steering mechanism, and a vehicle. Background Art

[0002] With the development of rail transportation, suspended monorail has become the preferred solution for solving traffic congestion problems in small and medium-sized cities. Suspended monorail is a new type of rail transit system. As its mileage increases, vibration intensifies, the service environment of various components deteriorates, and structural problems such as the running mechanism and car body are increasingly exposed.

[0003] Suspended monorail transit uses a running mechanism mounted on top of a carriage via a suspension mechanism. The running wheels on the running mechanism run on the track, driving the carriages. When a suspended monorail vehicle needs to turn, a motor drives the steering shaft, which in turn drives the swing arm and steering wheel on the shaft to swing, causing the steering wheel to contact and move along the track side panels, achieving a change in direction.

[0004] However, during the steering process, the track side plates exert force on the steering wheels, causing the rotating shaft to generate torque, which is then transmitted to the motor, causing damage to the motor and greatly shortening its normal service life. Summary of the Invention

[0005] In order to solve one of the above-mentioned technical defects, an embodiment of the present application provides a stop-type steering shaft connection device, a steering mechanism and a vehicle, which offsets the influence of the torsional torque on the motor and is also suitable for connections between different shaft diameters.

[0006] In a first aspect, an embodiment of the present application provides a stop-type steering shaft connection device, comprising a coupling, a stop clamp, and a stop plate. The coupling is provided at both ends with cavities matching the output shaft of the steering motor and the steering shaft, respectively. The lower column of the coupling is located within the central cavity of the stop plate, and the stop clamp is fixedly mounted on the column located within the stop plate.

[0007] The retaining clip is a cylindrical structure with a hole, and the hole is matched with the lower cylinder of the coupling. One side of the retaining clip is cut and separated and fixed by a first fastener. The other side of the retaining clip is provided with a protrusion and a second fastener is fixedly installed on the protrusion. The two ends of the second fastener are provided with top caps.

[0008] The stop plate is a cylindrical structure with a cavity. Two abutment caps are provided on the inner cavity wall of the stop plate. The two abutment caps are arranged in parallel and symmetrically. When the retaining clamp rotates 180° in two directions, the two top caps are in tight contact with the corresponding abutment caps respectively.

[0009] The retaining clip and the coupling are circumferentially fixed via a key connection.

[0010] Keyways are provided on the inner walls of the two cavities of the coupling.

[0011] A through hole is provided on the upper column of the coupling.

[0012] An arc plate convex block is provided on the inner wall of the hole cavity of the stop disk, and two abutting caps are respectively arranged at two ends of the arc plate convex block.

[0013] The rear end of the abutting cap is provided with a threaded column head, and both ends of the arc plate protrusion are provided with threaded holes. The abutting cap is fixed on the arc plate protrusion through threaded connection.

[0014] The first fastening member is a first bolt, and the second fastening member is a second bolt.

[0015] The second aspect of the present application provides a steering mechanism, including a steering motor, a steering shaft, a swing arm and a steering wheel. The steering motor is fixedly mounted on the frame of the running mechanism. The output shaft of the steering motor is vertically upward and fixedly connected to the steering shaft. The upper end of the steering shaft is fixedly connected to one end of the swing arm, and the other end of the swing arm is equipped with a steering wheel. The steering shaft is connected to the output shaft of the steering motor through the stop-type steering shaft connecting device. The output shaft of the steering motor is fixed in the lower cylindrical cavity of the coupling and is circumferentially fixed through a key connection. The steering shaft is clamped in the upper cylindrical cavity of the coupling and is circumferentially fixed through a key connection. The stop plate is fixed on the frame of the running mechanism.

[0016] A third embodiment of the present application provides a vehicle, comprising: a carriage and a running system disposed on the carriage, wherein the running system is provided with a steering mechanism as described above. Using a stop-type steering shaft connection device and its steering mechanism provided in an embodiment of the present application, after the force applied to the steering wheel is transmitted to the steering shaft, causing torque to form, the top cap of the retaining clamp and the stop cap of the stop plate contact and abut against each other to buffer and eliminate the force, thereby avoiding damage to the steering motor and ensuring the normal service life of the steering motor. Furthermore, couplings with different cavity models can be selected based on the different shaft diameters of the steering motor output shaft and steering shaft, thereby achieving connection between shafts of different diameters.

The lower column of the coupling 1 is located in the central hole of the stop plate 3, and a retaining clip 2 is fixedly sleeved on the column inside the stop plate 3.

[0028] like Figure 3-4 As shown, the retaining clip 2 is a ring-shaped columnar structure with a cavity, and the cavity is matched with the lower column of the coupling 1. One side of the retaining clip 2 is cut and separated and fixed by a first fastener. The other side of the retaining clip 2 is provided with a protrusion and a second fastener is fixedly installed on the protrusion. Top caps 23 are provided at both ends of the second fastener.

[0029] Specifically, the first fastening member is a first bolt 21 , and the second fastening member is a second bolt 22 .

[0030] like Figure 5 As shown, the stop plate 3 is a cylindrical structure with a cavity. Two stop caps 31 are provided on the inner cavity wall of the stop plate 3. The two stop caps 31 are arranged in parallel and symmetrically. Figure 6As shown, when the retaining clip 2 is rotated 180° to two positions, the two top caps 23 are in close contact with the corresponding abutting caps 31 respectively.

[0031] The retaining clip 2 and the coupling 1 are circumferentially fixed via a key connection.

[0032] Keyways 11 are provided on the inner walls of the two cavities of the coupling 1 .

[0033] A through hole 12 is provided on the upper column of the coupling 1 .

[0034] An arc plate protrusion 32 is provided on the inner wall of the cavity of the stop plate 3 , and two abutting caps 31 are respectively provided at both ends of the arc plate protrusion 32 .

[0035] The rear end of the abutting cap 31 is provided with a threaded column 33 , and both ends of the arc plate protrusion 32 are provided with threaded holes. The abutting cap 31 is fixed to the arc plate protrusion 32 through threaded connection.

[0036] like Figure 7 As shown, a steering mechanism includes a steering motor 4, a steering shaft 5, a swing arm 6 and a steering wheel 7. The steering motor 4 is fixedly mounted on the frame 8 of the running mechanism. The output shaft of the steering motor 4 is vertically upward and fixedly connected to the steering shaft 5. The upper end of the steering shaft 5 is fixedly connected to one end of the swing arm 6. The other end of the swing arm 6 is equipped with a steering wheel 7. The steering shaft 2 is connected to the output shaft of the steering motor 1 through the stop-type steering shaft connecting device. The output shaft of the steering motor 4 is fixed in the lower cylindrical hole of the coupling 1 and is circumferentially fixed through a key connection. The steering shaft 5 is clamped in the upper cylindrical hole of the coupling 1 and is circumferentially fixed through a key connection. The stop plate 3 is fixed on the frame 8 of the running mechanism.

[0037] Instructions for use: When using this application, first loosen the first bolt 21 on the retaining clamp 2, fix the retaining clamp 2 on the lower column of the coupling 1 and achieve circumferential fixation through a key connection, then sleeve the lower column of the coupling 1 with the output shaft of the steering motor 4 and achieve circumferential fixation through a key connection, fix the stop plate 3 on the frame 8 of the running mechanism, adjust its position so that one of the top caps 23 of the retaining clamp 2 contacts and presses tightly with one of the stop caps 31 on the stop plate 3, when the rotating motor 4 controls the coupling 1 to rotate 180°, the other top cap 23 of the retaining clamp 2 contacts and presses tightly with the other stop cap 31 in the hole cavity of the stop plate 3, finally fix the steering shaft 5 in the upper column of the coupling 1 and achieve circumferential fixation through a key connection, and install the swing arm 6 and the steering wheel 7 in sequence.

[0038] The installation effect of this application on the frame 8 of the running mechanism is as follows Figure 8 shown.

[0039] During the movement, the steering wheel 7 is subjected to the force exerted by the side wall of the track, which is transmitted to the steering shaft 5 through the swing arm 6 to form a torque. The steering shaft 5 rotates, and due to the circumferential fixation of the key connection, it drives the coupling 1 to rotate. The coupling 1 drives the retaining clamp 2 to rotate. After rotating to a certain position, the top cap 23 is in close contact with the corresponding abutment cap 31, limiting its continued rotation, preventing it from transmitting the torque to the motor shaft and causing damage to the steering motor 4, thereby ensuring the normal service life of the steering motor 4. At the same time, according to the steering motor output shaft and steering shaft with different shaft diameters, locking rings with different cavity models can be selected to achieve connection between different shaft diameters.
