Abstract
The utility model relates to a cab floor of a heavy truck. The cab floor comprises a left floor, a middle floor and a right floor which are connected in sequence; the middle floor is provided with an arc transitional protrusion part; the left floor and the right floor are provided with an arc transitional sinking part; the left floor, the right floor and the middle floor are arranged on a cross beam; the force can be transferred to the frame through the cross beam. The cab floor is simple in structure and reasonable in design, can simplify the traditional cab floor consisting of nine parts into the one with four parts, thereby greatly reducing the quantities of parts and welding points, widening the space inside the cab, improving comfort level, and the cab floor can ensure uniform stress, thereby avoiding cracking of the cab floor after the floor is fatigue due to stress.
Description
Technical field
The utility model relates to heavy duty truck field of components, relates in particular to a kind of floor for cab of heavy truck.
Background technology
The cab floor assembly of traditional heavy duty truck is by nine most of assemblies: ,Zhong floor, ,You floor, left floor, seat beam, left longeron, right vertical beam, left floor skirt beam, right floor skirt beam and crossbeam.The number of parts used is numerous, complex structure, stock utilization are low, manufacture and maintenance management cost huge; And cab floor structure design is too weak, longeron bears the load on operator's compartment top, crossbeam bears transverse load and vehicle body reverses the load of transmitting, connection between longitudinal and transverse beam lacks reinforcement structure, stress cannot effectively transmit, concentrate and to act on beam point of connection in length and breadth, the crossbeam effect of impact load stress that is subject to for a long time travelling simultaneously, makes body platform cracking after stressed fatigue.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of floor for cab of heavy truck is provided.
The utility model is to be achieved through the following technical solutions:
A kind of floor for cab of heavy truck, comprise the left floor, middle floor, the right floor that connect successively, described middle floor is provided with arc transition lug boss, described left floor and right floor are provided with the depressed part of arc transition, described left floor, middle floor and right floor are all arranged on a crossbeam, by described crossbeam, suffered power are delivered on vehicle frame.
As preferably, described left floor and right floor are arranged on respectively the both sides of middle floor.
As preferably, described crossbeam is arranged on the end of left floor, middle floor and right floor, by single-piece punching press, is made.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, arrange rationally, nine traditional most of cab floors that form are simplified to four major parts, significantly reduce number of parts and weld nugget quantity, increase and drive inner space, improve comfort level; Make its uniform stressed simultaneously, avoid making body platform cracking after stressed fatigue.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of floor for cab of heavy truck, comprise the left floor 1, middle floor 2, the right floor 3 that connect successively, described middle floor 2 is provided with arc transition lug boss 4, described left floor 1 and right floor 3 are provided with the depressed part 5 of arc transition, described left floor 1, middle floor 2 are all arranged on a crossbeam 6 with right floor 3, by described crossbeam 6, suffered power are delivered on vehicle frame.
Described left floor 1 and right floor 3 are arranged on respectively the both sides of middle floor 2, and described crossbeam 6 is arranged on the end of left floor 1, middle floor 2 and right floor 3, by single-piece punching press, is made.
