Adaptive brakes for rail vehicles

Abstract

The invention discloses an adaptive brake for a rail vehicle. A guide sleeve is installed on a mounting frame, a two-way oil cylinder is installed in the guide sleeve, and a guide push plate is connected to the front end of the oil cylinder piston rod of the two-way oil cylinder. A spring is installed between the guide sleeves; a guide groove is opened on the lower side wall of the guide sleeve, and a brake caliper connection block is installed on the lower side wall of the guide push plate, and the brake caliper connection block is stuck in the guide groove; The brake arm of the caliper is connected to the brake caliper connection block through a rotating shaft. The present invention has the following technical effects: when the track gauge size deviates from the braking size of the brake, since the guide sleeve can move axially relative to the frame plate, the entire brake can move axially to adapt to the track rail during braking. To avoid one-side contact and the other side not receiving force or not enough force, to achieve the designed braking state and braking force.

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.
