Description
Technical field
The disclosure relates generally to transport Wagon Tech field, is specifically related to transport Truck Frame Model, particularly relates to the end on vehicle frame
Shelf structure.
Background technology
Cargo vehicle is commonly referred to as lorry, also referred to as truck, refers to the automobile being mainly used in transporting goods, now has wide
Market prospect.Such as: along with the rapid rising of ecommerce in recent years, the shopping idea of people is transferred to from solid shop/brick and mortar store the most gradually
In net purchase, thus promote the rise of express delivery industry with fast-developing.
The development of express delivery industry is from not being used for transporting the support of the freight container car of express delivery commodity.Container car generally comprises
Vehicle frame, headstock and truck body.Vehicle frame includes crossbeam, is arranged on the wheel of crossbeam both sides.Vehicle frame is typically chosen on crossbeam perpendicular
Directly being provided with longeron, longeron is fixing with crossbeam to be connected, and then longeron is fixed with frame chassis away from the one end on ground and is connected, underframe
On truck body is set.But along with developing rapidly of express delivery industry, express delivery commodity are the most, and then require the number of freight container car
Amount increases therewith, but this can cause express delivery cost increase.But owing to there is strict size Control in country to freight container car
Including bodywork height, width, length and vehicle frame, requirement, includes that crossbeam does not allow to carry out the transformation operations such as welding, therefore by increasing
Add the overall height of freight container car and length is infeasible to increase railway carriage volume, therefore keep original bodywork height, width
And in the case of length is constant, increase railway carriage volume always this area of container car for solving the technical problem that.
Utility model content
In view of drawbacks described above of the prior art or deficiency, it is desirable to provide a kind of spacing by reducing railway carriage and crossbeam
Increase the Undercarriage structure of railway carriage volume.
This utility model provides a kind of Undercarriage structure, and including frame type base frame body, underframe body includes along underframe body
The spaced body transom of length direction, underframe body also includes the bottom surface of the end face for reducing crossbeam and underframe body
The backing plate assemblies of spacing, backing plate assemblies is fixedly connected on the bottom of body transom, and backing plate assemblies is fixed with body transom
The width of the part connected is more than the width of corresponding body transom, and backing plate assemblies is provided with the peace for removably connecting with crossbeam
Dress hole.
The Undercarriage structure that this utility model provides, by setting backing plate assemblies between crossbeam and underframe body, wherein backing plate
Assembly is fixing with underframe body to be connected, and backing plate assemblies is connected by installing hole and crossbeam are fixing, and then underframe body is fixed on greatly
Above beam, thus remove the use of longeron from, it is achieved that reduce the purpose of railway carriage and the spacing of crossbeam, can ensure that overall height is constant
In the case of, reach to add the effect of the volume of railway carriage, thus lower cost of transportation.Meanwhile, due on backing plate assemblies
The width of the part fixing connection with body transom is more than the width of corresponding body transom, thus adds body transom with big
