Adaptive brake for railway vehicle

Abstract

The invention discloses an adaptive brake for a railway vehicle. A guide sleeve is installed on an installation frame. A two-way oil cylinder is installed in the guide sleeve. A guide push plate is connected to the front end of an oil cylinder piston rod of the two-way oil cylinder. A spring is installed between the guide push plate and the guide sleeve. A guide groove is formed in the lower side wall of the guide sleeve. A brake caliper connecting block is installed on the lower side wall of the guide push plate and clamped into the guide groove. A brake arm of a brake caliper is connected to the brake caliper connecting block through a rotating shaft. The adaptive brake for the railway vehicle has the beneficial effects that when deviation exists between the track distance and the brake braking dimension, the whole brake can move axially to adapt to the track distance in braking as the guide sleeve can move axially relative to a vehicle frame plate, the situation that single-side contact occurs, and the other side is not stressed or not sufficiently stressed is avoided, and a designed braking state and designed braking force are achieved.

Description

technical field [0001] The invention relates to an adaptive brake for rail vehicles Background technique [0002] Rail vehicle refers to the vehicle running on the track, including the shuttle car used in the endless rope continuous tractor system. The brakes used in the existing shuttle car are all fixed on the frame, and the center size of the two brakes is fixed. However, the gauge of the vehicle running track will be irregular and not uniform due to the size error of the installation and the specified range of the industry. The gauge of the installation track is wide or narrow. The misalignment will lead to a decrease in the braking force. In severe cases, the track will not be clamped, and the brake will fail, which will affect the safe operation of the equipment. Contents of the invention [0003] The object of the present invention is to provide an adaptive brake for rail vehicles. [0004] The technical scheme of the present invention is an adaptive brake for rai...

[0002] Rail vehicle refers to the vehicle running on the track, including the shuttle car used in the endless rope continuous tractor system. The brakes used in the existing shuttle car are all fixed on the frame, and the center size of the two brakes is fixed. However, the gauge of the vehicle running track will be irregular and not uniform due to the size error of the installation and the specified range of the industry. The gauge of the installation track is wide or narrow. Mis-coincidence will lead to a decrease in braking force. In severe cases, the track will not be clamped, and the brake will fail, which will affect the safe operation of the equipment.
