Problems solved by technology

Existing large-scale tire-type cranes use a drum brake installed on the wheel axle to form a service braking system. The braking efficiency and heat dissipation of the drum brake are poor, and the braking force stability of the drum brake is poor. The braking force varies greatly and is not easy to control
Due to the poor heat dissipation performance, a large amount of heat will be accumulated during braking.
Brake pads and drums are prone to extremely complex deformations under the influence of high temperatures, which are prone to brake fading and chattering, resulting in a decrease in braking efficiency
As a result, the braking will not work, the braking distance will be large, and the braking force of each wheel will be uneven, which will pose a certain safety hazard.

Abstract

The invention provides a service braking system applied to a large tire type crane. The service braking system comprises a brake air chamber and brakes. The brakes are installed on axles. The axles comprise the front axle, the middle axle and the rear axle. The front axle comprises double front axle bodies. The middle axle comprises double middle axle bodies. The rear axle comprises double rear axle bodies. Each of the double front axle bodies, the double middle axle bodies and the double rear axle bodies is provided with one disc brake and one drum brake. The large tire type crane using the service braking system is good in braking effect and short in braking distance, and the service braking safety is guaranteed.

Description

technical field [0001] The invention relates to a large tire type crane, in particular to a service braking system applied to the large tire type crane. Background technique [0002] Large-tired cranes are swinging jib cranes that use a tire-type chassis to travel. Due to its large lifting capacity and heavy body weight, it requires high braking performance. Generally, the braking system of a large rubber-tyred crane consists of a service braking system, an auxiliary braking system and a parking braking system. The service brake system is operated by the driver with his feet, so it is also called the foot brake system. Its function is to slow down the moving car or stop it in the shortest distance. Existing large-scale tire-type cranes use a drum brake installed on the wheel axle to form a service braking system. The braking efficiency and heat dissipation of the drum brake are poor, and the braking force stability of the drum brake is poor. The braking force varies grea...
