Abstract

The invention discloses a drive braking system of a rack-and-pinion vehicle. The system comprises a shaft axle, a gear box, a rack-and-pinion wheel, a driving device and a braking device, wherein thegear box is arranged around the shaft axle, the rack-and-pinion wheel is arranged on the shaft axle through a rack-and-pinion wheel seat, the driving device drives the rack-and-pinion wheel to rotate,and the braking device limits rotation of the rack-and-pinion wheel; the driving device comprises a driven gear arranged on the shaft axle, the braking device comprises a brake drum arranged on a hollow shaft, the driven gear and the brake drum are arranged on the two sides of the rack-and-pinion wheel seat correspondingly, and the driven gear is fixedly connected with the rack-and-pinion wheel seat; the end, opposite to the brake drum, of the rack-and-pinion wheel seat extends towards the brake drum to form a mounting part, and the mounting part penetrates into the brake drum and is fixedlyconnected with the brake drum; and the driving device and the braking device are both mounted on the gear box. Therefore, the rack-and-pinion wheel, the driven gear and the brake drum can be connectedinto a whole, the driven gear can be driven by the driving mechanism to drive the rack-and-pinion wheel to rotate, and reliable braking of a device provided with a rack-and-pinion wheel driver can berealized.

Description

technical field [0001] The invention belongs to the technical field of rack car driving, and in particular relates to a rack car driving and braking system. Background technique [0002] The rack car is a mining locomotive that increases the climbing ability by means of the rack on the track bed and the gear on the locomotive. There are a large number of physical locomotives running on different mountain routes abroad. Although there is no rack vehicle running on mountain routes in China, its similar technology has certain applications in the field of amusement facilities and coal mining. [0003] The rack car is suitable for rack lines above 60‰, and has extremely high requirements on the braking system of the vehicle. The drum brake device has the characteristics of large braking torque and is more suitable for braking rack cars. Due to the large diameter of the rack wheel and the arrangement of teeth on the outer periphery, the brake drum cannot be braked around the ra...
