Swinging frame type rear wheel driving structure for spreading machine

Abstract

The invention discloses a swinging frame type rear wheel driving structure for a spreading machine. The swinging frame type rear wheel driving structure for the spreading machine comprises a first driving unit and a second driving unit; the first driving unit and the second driving unit are oppositely arranged; the structures of the first driving unit and the second driving unit are as same as each other; the first driving unit and the second driving unit both comprise brackets, rotating shafts, driving components, first rotating components and second rotating components; hinging holes are formed in the brackets; the rotating shafts penetrate through the hinging holes in the brackets, are arranged perpendicular to the brackets and are used for the brackets to rotate around; the driving components are arranged on the brackets; the first rotating components and the second rotating components are all arranged on the same sides of the brackets; the structures of the first rotating components and the second rotating components are as same as each other; the first rotating components and the second rotating components all comprise wheel axles and driving wheels; one ends of the wheel axles are connected with the driving components; and the other ends of the wheel axles are connected with the driving wheels. According to the swinging frame type rear wheel driving structure for the spreading machine, the tire ground area is increased by using four driving wheels so that the driving capacity is improved; by using the brackets capable of rotating, the road adaptability of the four driving wheels is made better so that the vehicle slipping possibility is reduced in a maximized manner; and by using independent driving units, and the speeds of left and right driving wheels can be independently controlled to improve the flexibility of a product.

Description

technical field [0001] The invention belongs to the technical field of road construction machinery, and in particular relates to a swing-type rear wheel drive structure for a paver. Background technique [0002] For a long time, wheeled paver has been favored by users for its good maneuverability, high driving speed, convenient transition, and flexible use. It is suitable for special fields such as municipal road maintenance and construction, community roads and garden road construction. However, compared with the crawler paver, the wheeled paver also has more obvious disadvantages, such as poor driving force and poor stability of the fuselage. [0003] At present, the more common wheeled paver on the market generally has two rear drive wheels, and the anti-skid performance and road adaptability of the rear-wheel drive structure are poor. , there is a rear 4-wheel drive structure, but the rear 4-wheel drive structure in the prior art uses rigidly fixed driving wheels, which...

Problems solved by technology

However, compared with the crawler paver, the wheeled paver also has obvious disadvantages, such as poor driving force and poor stability of the fuselage.

[0003] At present, the more common wheeled paver on the market generally has two rear drive wheels, and the anti-skid performance and road adaptability of the rear-wheel drive structure are poor. , a rear 4-wheel drive structure has appeared, but the rear 4-wheel drive structure in the prior art uses rigidly fixed driving wheels, which leads to poor turning performance of the vehicle and affects the flexibility of the product
