Base of passive hydraulic brake clamp forceps

Abstract

The invention relates to a base of passive hydraulic brake clamp forceps for a low-floor tramcar. The base comprises a brake cylinder mounting portion, bracket pin mounting portions, lever assembly mounting portions and a brake pad assembly mounting portion. The brake cylinder mounting portion comprises semi-closed mounting space composed of an end face supporting plate, reinforcement plates and a supporting bottom plate. Four threaded bosses are evenly distributed on the front end face of the end face supporting plate and around a brake cylinder spigot hole. The reinforcement plates are of a right triangle plate-shaped structure, the vertical right-angle side of the left reinforcement plate and the vertical right-angle side of the right reinforcement plate are connected with the left end face and the right end face of the end face supporting plate respectively, and the horizontal right-angle sides of the reinforcement plates are coplanar with the lower end face of the end face supporting plate. The front end face of the supporting bottom plate is perpendicularly connected with the lower end face of the end face supporting plate. The left end face and the right end face of the supporting bottom plate are connected with the perpendicular right-angle sides of the reinforcement plates. The base of the clamp forceps is additionally provided with reinforcement ribs, the threaded bosses, limiting check blocks and other reinforcement structures, so that the stress stability of the base is improved, the structural layout of the base is optimized, and the weight of the base is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicle braking, in particular to a passive hydraulic brake caliper base for low-floor trams. Background technique [0002] Trams are driven by electric power, which has large transport capacity, low energy consumption, and low environmental pollution. Due to the special track running on the ground, the construction cost is low, and it has obvious advantages over urban public transportation such as buses and subways. . Modern trams adopt a low-floor structure and do not need to set up special platforms. Passengers get on and off easily, and are widely favored in the construction planning of new urban rail transit systems. [0003] Modern trams adopt a low-floor structure for the convenience of passengers getting on and off, which puts forward high requirements for the installation space of the braking system. Modern low-floor trams usually adopt a compact hydraulic braking system to meet the demandi...

Problems solved by technology

[0005] The base of the existing passive hydraulic brake caliper can realize the connection and bearing function of each module. For example, Chinese patent 201310034768.6 discloses a hydraulic brake caliper device, which includes a caliper base, a brake cylinder, a lever member, The lever pin and the clamp assembly and other components, wherein the clamp base includes interfaces such as the brake cylinder installation part, the brake pin installation part, and the lever pin installation part, but the existing clamp base does not have complex bearings for the clamp base. There is also room for optimization in the layout scheme of each interface part.
