Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

As shown in fig. 1-4, it shows that the utility model discloses a dual-purpose power bogie of flat ground climbing for sightseeing small train, includes: the front and rear ends of the bottom of the bogie body 1 are respectively provided with a front wheel shaft 11 and a rear wheel shaft 12, and the two ends of the front wheel shaft 11 and the rear wheel shaft 12 are respectively provided with a front wheel 111 and a rear wheel 121. The front wheel shaft 11 is provided with a front wheel driving motor 13 connected with the front wheel shaft 11, and when the front wheel driving motor 13 is powered on, the front wheel shaft 11 is driven to rotate by the front wheel driving motor 13, and the front wheel shaft 11 rotates to drive the front wheels 111 and the rear wheels 121 to rotate in a driven manner. The front wheels 111 and the rear wheels 121 run on the common wheel rail 2, and run on the flat ground of the sightseeing train.

When the train runs on a road section with a high slope or a road section with a high slope, the friction force between the front wheels 111 and the rear wheels 121 and the common wheel rail 2 is small, so that the train cannot climb the slope with the high slope. At this time, the power supply to the front wheel drive motor 13 is cut off, and the power supply is switched to the climbing gear group 14. The climbing gear set 14 includes a climbing gear 141 and a gear driving motor 142 connected to each other, and the climbing gear 141 is sleeved on the rear wheel axle 12.

Therefore, the utility model discloses be provided with damping spring 17 and be used for the shock attenuation of little train. Specifically, the front wheel shaft 11 and the rear wheel shaft 12 are respectively connected to the axle holes of a bearing block 16, the bogie body 1 is provided with a sliding groove 15, the bearing block 16 is slidably connected to the sliding groove 15, the upper part of the bearing block 16 is connected with a damping spring 17, and the other end of the damping spring 17 is connected to the bogie body 1. When the chassis of the small sightseeing train bumps, the whole bogie body 1 can pitch up and down along with the bump, the bearing seat 16 slides up and down along the sliding groove 15 relatively, and the damping spring 17 deforms in a compression or rebound mode, so that the effect of relieving vibration is achieved.

Further, in order to prevent the truck body 1 from moving up too much as it is bumped, the bearing seat 16 slides out of an opening in the rim of the truck body 1. Therefore, the edge of the bogie body 1 is provided with the stop support plate 18, and the stop support plate 18 is positioned below the bearing seat 16, so that the bearing seat 16 can be limited in sliding.

Further, due to the toothed circumference of the creep gear 141, it is different from the round arc circumference of the rear wheel 121. Therefore, the rear wheel shaft 12 is sleeved with an in-wheel bearing 122, and an outer ring of the in-wheel bearing 122 is rotatably connected with the rear wheel 121. The linear velocity difference between the crawling gear 141 and the rear wheel 121 is counteracted through the rotational speed difference between the inner ring and the outer ring of the in-wheel bearing 122, and the stable operation of the sightseeing trolley is realized.

Further, a front wheel brake disk 112 is provided on the front wheel 111 side, the front wheel brake disk 112 is keyed to the front wheel shaft 11, a rear wheel brake disk 123 is provided on the rear wheel 121 side, and the rear wheel brake disk 123 is keyed to the rear wheel shaft 12. Further, a pneumatic brake bracket 161 is fixedly connected to the bearing housing 16, and a pneumatic brake 162 is connected to the pneumatic brake bracket 161. The pneumatic brake 162 floats up and down along with the bearing seat 16 to ensure a gap between the pneumatic brake 162 and the top of the brake disc, so as to prevent the pneumatic brake 162 and the brake disc from colliding when the vehicle moves, and the brake of the pneumatic brake 162 holds the brake disc to perform a braking function during emergency braking.

In addition, a bogie core 4 is provided for connecting the bogie body 1 with the vehicle compartment.

Further, the front wheel axle 11 and the rear wheel axle 12 are arranged in parallel.

The utility model discloses a dual-purpose power bogie of flat ground climbing for small sightseeing train's working process is described below with the accompanying drawing:

when the small sightseeing train runs on the flat ground, the front wheel driving motor 13 is electrified, the front wheel driving motor 13 drives the front wheel shaft 11 to rotate, the front wheel shaft 11 rotates to drive the front wheels 111 and the rear wheels 121 to rotate in sequence, and the running of the small sightseeing train on the flat ground is completed. When the sightseeing train runs on a climbing slope, the power supply to the front wheel driving motor 13 is cut off, the power supply is switched to the gear driving motor 142, the gear driving motor 142 drives the crawling gear 141 to rotate, and the rear wheel 121 and the front wheel 111 are driven to rotate in sequence; at the moment, the rear wheel 121 and the front wheel 111 rotate to run on the common wheel rail 2 in a driven mode, the crawling gear 141 is meshed with a rack in the rack 3 railway to run in the rack 3 railway, and slope climbing and mountain climbing running on the high slope of the sightseeing train are completed.
