Preferably, the wheel is fixed on frame assembly both sides, three wheels are fixed in wherein side.
Preferably, the towing pin is connected with tractor.
Preferably, it is fixed with vehicle spare tyre on the spare wheel carrier.
The invention also discloses a kind of special semitrailer of bearing-type, including described bearing-type walking mechanism, traction
Car and towing pin, wherein tank body front end weld towing pin, and tank body rear end is bolted bearing-type walking mechanism；The traction
Car is with traction pin assembly by drawing pin connection.
Prior art is contrasted, the beneficial effects of the utility model are：
1. the utility model is by the chassis skeleton of special semi-trailer walking mechanism by half bearing-type that is connected with tank body entire body
The bearing-type being only connected with tank body part has been changed to, has alleviated the weight of chassis skeleton.
2. spare wheel carrier of the present utility model, fire extinguisher bracket, mud guard assembly, valve box, rear molding assembly are designed to mark
It is convenient that quasi- part is later design, manufacture is brought, and more improves the interchangeability of parts.
3. Vehicle preparation quality is small, 40 tons of national Specification walking mechanism and tank body totality freight weight limit, at walking mechanism bottom
In the case of disk skeleton specification identical, the structure is compared to the chassis skeleton being connected with tank body entire body of half bearing-type, chassis bone
Frame length reduces close to half, and quality mitigates about 1100Kg, so as to transport more goods.
4. tractor is no longer attached with walking mechanism, but is attached with drawing pin assembly on tank body, so
The load of vehicle undertakes a part by tank body so that the load of walking mechanism carrying reduces, and reduces the intensity to walking mechanism
It is required that it is easy to the loss of weight of walking mechanism.
5. bearing-type walking mechanism is bolted with tank body, convenient maintenance ensures the tank body life-span with exchanging tank body.
