Description
Technical Field
The utility model relates to a freight vehicle field specifically says and relates to an obstacle-surmounting crawler wheel for obstacle-surmounting freight vehicle.
Background
The truck is a vehicle for transporting goods in short distance, and has two types of power and no power, and the specific structure is different. The goods shelf is widely used in various places needing to transport goods in short distance, such as supermarkets and various small goods markets. The most common structure of such trucks is a cargo platform with wheels on the lower portion of the platform and a push handle attached to the platform to push the truck to transport a certain amount of cargo over a short distance. And part of the trucks are provided with motors or engines so as to improve the cargo carrying capacity and the cargo carrying speed and save manpower. However, such trucks, whether powered or unpowered, have a significant disadvantage in that they have poor ride-through capability and are generally only suitable for use on flat ground. The current trucks cannot be used once they encounter uneven ground or need to go upstairs, even just a few steps.
Because current trucks do not have obstacle crossing capability, the need for obstacle crossing is realistic for actual cargo handling. In order to solve this problem, there is marketed a trolley using obstacle crossing wheels consisting of three small wheels arranged in an equilateral triangle. When the obstacle crossing wheel is used on the flat ground, two wheels always contact the ground, when an obstacle such as a step is encountered, the front wheel stops, at the moment, the operator increases the force to push the freight car, so that the gravity center of the freight car is raised, the center of the obstacle crossing wheel is driven to be raised, the small wheel positioned on the upper side in the obstacle crossing wheel moves forwards to contact the step, the obstacle crossing wheel realizes rolling, and the obstacle crossing wheel turns over the step and can push the freight car to continue to move forwards. Although the obstacle crossing wheel can realize obstacle crossing, the resistance change of vehicle pushing is large when the obstacle crossing is carried out, the vehicle actually enters an intermittent advancing state when pushed by people, the vibration of cargos on the vehicle is large, and an operator not only has the advantages of hard pushing and difficult advancing, but also has strong jolt, so the obstacle crossing wheel is not friendly to the operator.
