Problems solved by technology

[0005] 1) Due to long-distance continuous braking or frequent use of brakes, the brake drum is prone to heat, which will generate high temperature and even sparks, so it is easy to cause the danger of brake failure or explosion; in addition, If the temperature rise of the vehicle is too high when braking, the brake pads will be easily worn, thus shortening the service life of the brake device;
[0006] 2) In addition, since the service brake device and the parking brake device are controlled by two sets of independent control mechanisms, it often occurs that the service brake and the parking brake are simultaneously performed due to the driver's misoperation, and the This situation is very dangerous in driving, and there will be a phenomenon of vehicle flicking, and it will also greatly affect the wear of the engine and friction plates.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Depend on Figure 2 ~ Figure 6 It can be seen from the structural schematic diagram of the brake mechanism of the explosion-proof vehicle of the present invention that it includes a brake, a service brake control device, a parking brake control device and a flexible shaft, and the service brake control device and the parking brake control device are both It is connected with the brake through a flexible shaft. The service brake control device and the parking brake control device are connected to the flexible shaft at the same time to form an interlock. The brake is an outer shoe brake including a brake disc 4, and the brake disc 4 is a web-shaped hub, adjacent to There is a hollow structure between the two webs.

[0030] The brake also includes a left brake shoe 2 , a right brake shoe 11 , a left friction plate 3 , a right fr...

Abstract

The invention discloses a braking mechanism of an anti-explosion vehicle. The braking mechanism comprises a brake, a driving brake control device, a parking brake control device and a flexible shaft, wherein the driving brake control device and the parking brake control device are both connected with the brake through the flexible shaft and connected with the flexible shaft at the same time to form interlocking. The brake is an outer shoe type brake with a brake disc (4), wherein the brake disc (4) is a radial-plate-shaped hub, and the space between two adjacent radial plates is of a hollow structure. After the structure is adopted, a left brake shoe, a right brake shoe, a left friction plate and a right friction plate are all located outside the brake disc, and therefore ventilation is good, and temperature rise of the brake is restrained to a certain degree; in addition, the brake disc is the radial-plate-shaped hub, the effect of a fan is achieved when the brake disc is rotated, and therefore the cooling effect and the self-cleaning effect are good, the brake is high in thermal stability, and fundamentally, no heat fading phenomenon occurs on the aspect of the friction coefficient.

Description

technical field [0001] The invention relates to the technical field of braking systems of vehicles, in particular to a braking mechanism for explosion-proof vehicles in hazardous environments with explosive gas types I and II and environments with combustible dust. Background technique [0002] With the development of mechanical modernization, industrial electric vehicles are widely used in many places such as cargo handling, loading and unloading, stacking, etc., saving time and effort, and greatly improving production efficiency. However, in some dangerous environments with explosive gas and combustible dust, the explosion-proof performance of vehicles is particularly important. Therefore, the temperature rise control and spark control of explosion-proof vehicles are key technologies. At present, the braking system of explosion-proof vehicles mostly adopts two sets of braking devices. On the one hand, in the driving braking device (commonly known as the foot brake device),...
